Operation ‘Surgeon’ and Britain’s Post-War Exploitation of Nazi German Aeronautics MATTHEW UTTLEY
After 1945, Allied acquisition of intelligence on Nazi Germany’s wartime aeronautical innovations became one of the most important immediate post-war aims. From July 1945 to July 1947, Operation ‘Surgeon’ became the focus of British efforts to exploit Nazi aeronautical advances. The objectives of the operation were the evacuation of state-of-the-art equipment from aeronautical research institutes and the recruitment of high-grade aviation experts for postwar work in Britain. This article analyzes the conduct and results of Operation ‘Surgeon’. The limited literature on this topic has fuelled a popular orthodoxy which holds that the UK intelligence effort and policies to recruit German defence scientists were classic examples of the ‘British disease’, or a more general inability to exploit a technological opportunity that was harnessed so effectively by the other victorious Allies. Drawing on the experience of Operation ‘Surgeon’, the article challenges this orthodoxy that has dominated the historiography of Britain’s intellectual reparations from the Third Reich.
After 1940, Nazi Germany ‘set to work to investigate every possible idea for new aeronautical development’1 while the Allies, by contrast, pursued a strategy of incremental improvement on proven equipment. By July 1945, the British Chiefs of Staff had concluded that German science was ‘well in advance’ of Britain in the fields of high-speed aerodynamics, ballistics and rocketry.2 Though historians continue to debate relative technological achievement by the end of the war,3 the Chiefs of Staff were convinced that Germany had made ‘fantastic strides in … aero-research generally’,4 whereas the Allies had ‘few advanced projects’ under development.5 From July 1945 to July 1947, Operation ‘Surgeon’ became the focus of British efforts to exploit Nazi advances through the evacuation of state-of-the- art equipment from aeronautical research institutes and the recruitment of high-grade aviation experts for post-war work in Britain. The operation became one element of a wider plan to plunder ‘the enemy’s store of technical and scientific knowledge’; a plan that the Chiefs of Staff identified as one of their most important immediate post-war priorities.6 This article analyzes the conduct and results of Operation ‘Surgeon’. The justifications for an in-depth study are twofold. First, given the significance attached to science, technology and methods of war by the Chiefs of Staff, there has been surprisingly little work on early post-war scientific and technical intelligence.7 Consequently, this study helps to fill an important gap in the history of British intelligence, particularly on the relationship between intelligence and the content and direction of post-war technology policy. Second, in contrast to the vast literature covering US extraction of ‘intellectual reparations’ from Germany after 1945, there are few detailed historical studies of the British experience.8
Instead, the historiography has been dominated by a small number of texts that treat technology transfer from Germany as part of a broader critique of British post-war aviation policy. These studies hold that the UK effort to appropriate German aeronautical developments was a classic example of the ‘British disease’, or a more general inability to exploit a technological opportunity that was harnessed so effectively by the other victorious Allies. In this context, a detailed analysis of Operation ‘Surgeon’ provides a means to evaluate the validity of this popular orthodoxy. The first section outlines the antecedents of Operation ‘Surgeon’ and key phases in its execution, while the second section analyzes the impact of the physical hardware and elite experts who were extracted from Germany on the post-war British aircraft programme. The concluding section challenges the popular assumptions that have dominated the historiography of Britain’s ‘intellectual reparations’ from the Third Reich.
OPERATION ‘SURGEON’: ANTECEDENTS AND EXECUTION After 1939, Germany mobilized resources for high-speed aircraft development in an attempt to offset its numerical inferiority in conventional aircraft production. One consequence was that by mid-1944, German aerodynamic research had access to more than 78 wind tunnels of which 19 could be used for high-velocity aerodynamics in the transonic and supersonic range.9 By late 1944, applied research using these facilities was manifested in the relative performance of the Messerschmitt (Me) 262 twinjet fighter and the Me 163B tailless rocket-propelled interceptor when compared with Allied alternatives. By contrast, with the outbreak of war ‘all thoughts of supersonics’ in Britain had been ‘pushed into the background and forgotten’10 as attention focused on evolutionary refinement of established aircraft designs. Though a ‘high speed’ variable density wind tunnel had been completed by the Royal Aircraft Establishment (RAE) at Farnborough in 1942, this was only capable of operating at subsonic speeds up to Mach 0.8 and no wartime efforts were made to provide workable wind tunnels capable of covering the transonic range from Mach 0.85 to Mach 1.15 or the supersonic range from Mach 1.15 onwards. As Wood points out, ‘while Germany was spending a fortune on high-speed tunnels and trials and developing a variety of new wing shapes and sections, Britain was largely content to soldier on with 600mph (966km) as an approximate objective’.11
In early April 1945, a crucial catalyst for Britain’s post-war exploitation of German wartime innovations was the discovery by the advancing 1st US Infantry Division of the Hermann Göring Aeronautical Research Institute (Luftfarhtforschungsanstalt Hermann Göring) located in the British Zone of Occupation at Völkenrode four miles west of Brunswick. Völkenrode was one of Nazi Germany’s premier aeronautical research centres12 comprising seven elite institutes concerned with aerodynamics, gas dynamics (supersonic), strength of materials, engines, special engines (rockets and gas turbines), weapons and theoretical ballistics. During early May 1945, with Völkenrode under temporary US Army control, the British Ministry of Aircraft Production (MAP) Director of Scientific Research, Ben Lockspeiser, visited the establishment and assessed that the aerodynamic, supersonic and high speed equipment is far ahead of anything in this country, and as far as my knowledge goes, ahead of American equipment also. It is probably true to say that in several directions the technical equipment of this establishment is unsurpassed anywhere.13
Lockspeiser made four recommendations to the Minister of Aircraft Production.1
The first was to send to Völkenrode two British experts in the activities of each institute to interrogate professors and section leaders and produce short accounts of the main lines of activity. The second was that when Völkenrode was handed over to the British Army a member of the Directorate of Scientific Research staff should take over technical responsibility on the grounds that the equipment was ‘of unique value’ which should remain ‘in the hands of scientists’. Third, he recommended transfer of the more vital equipment Britain lacked, and would ‘inevitably lack for some years’, to the new RAE site at Bedford. Finally, Lockspeiser advocated that the German scientists at Völkenrode ‘who are really first class’ should be brought to the UK ‘to wor
k under supervision’. He stressed that time was of the essence because the inter-Allied Law No. 22 decreed that all warlike research in Germany was to cease by 22 June 1946.
Within four days a consensus emerged among senior MAP officials on the proposals. On 14 May 1945, the Controller of Research and Development advised the Minister of Aircraft Production that the MAP should evacuate the equipment and interrogate well-qualified personnel at Völkenrode.15 The Assistant Chief Executive, also Chairman of the Committee to Co-ordinate MAP interests in Germany and Austria, endorsed the urgent need to transfer the Völkenrode equipment to the Bedford site and endeavoured to ‘arrange accordingly’.16 Subsequently, MAP proposals for the exploitation of aeronautical scientific material at Völkenrode and other establishments in the British Zone of Occupation were refined and presented to the Assistant Chief of the Air Staff (Policy), Air Vice-Marshal William Dickson, on 6 July 1945.17
Lockspeiser’s suggestion to bring German aeronautical experts to Britain for long-term exploitation was more problematic. A scheme administered by the British Intelligence Objectives Sub-Committee (BIOS) already catered for the short-term interrogation of German scientists in Britain.18 However, ongoing deliberations between the Whitehall ministries with an interest in German scientists were precluding an overall British decision on long-term employment policy, and difficult questions about potential mechanisms to coordinate the allocation and recruitment of the specialists awaited an edict from the Combined Chiefs of Staff in Washington.
In April 1945, the British Chiefs of Staff Committee established the Deputy Chiefs of Staff (DCOS) Committee to advise on research and development questions affecting the armed services.19 By July 1945, the DCOS Committee had recognized the potential benefits for the British ‘Defence Services by the removal of a limited number of high grade individuals to the UK’.20 Correspondingly, the Joint Intelligence Committee and the Home Office argued on security grounds that such a plan was ‘fraught with danger’ because it would be ‘impossible to prevent the German scientists … obtaining all the information they want and passing this information out of the country’.
This impasse in Whitehall, coupled with ongoing negotiations with the Americans on possible ways to coordinate policies on German scientists, meant that the recruitment of aeronautical experts advocated by Lockspeiser seemed far from resolution.
On 12 July 1945, the extraction of German aeronautical and development facilities was endorsed at the Air Ministry under the codename Operation ‘Surgeon’. The operation was to be ‘essentially a MAP responsibility’ but run largely by the Royal Air Force (RAF) since the former ‘lacked the administrative and command structure to undertake the task’.22 In the absence of a firm decision to bring German experts to Britain, Operation ‘Surgeon’ had three objectives for completion within six months: to acquire information from German scientists on the spot, to evacuate23 important research equipment to MAP establishments and ‘to exploit German development of aircraft by continuing work on unfinished prototypes under construction in German aircraft firms’.24
On 31 August 1945, following a series of bureaucratic compromises the Defence Committee finally accepted the principle that German defence specialists could be recruited for ‘research in the national interest’, so Operation ‘Surgeon’ objectives were extended to include the selection and evacuation of ‘certain top-flight scientists and technologists for employment in Government research establishments and, to a lesser extent, in British aircraft firms’.25 With the issue of German scientists resolved, the essential elements of Lockspeiser’s proposals were in place. The focus of Operation ‘Surgeon’ initially lay with the Luftfarhtforschungsanstalt (LFA) facility at Völkenrode. The remit was quickly extended to include five other ‘Surgeon Stations’ in the British Zone, namely the Kaiser Wilhelm Institute (KWI) and the Aerodynamische Versuchs-Anstatt (AVA) at Göttingen which possessed small wind tunnels, the LFA outstation to Völkenrode at Trauen devoted to rocket motor research, the Reyershausen outstation of the AVA and the laboratories of Focke-Wulf at Detmold which were well equipped with apparatus for structural research. Collectively, these establishments covered all subjects concerned with the study and development of aircraft with the exception of electronics.26
Interrogation of German personnel and the removal of research equipment was the immediate responsibility of the MAP. On 25 July 1945, Professor W. J. Duncan was appointed as the Chief Scientist at Völkenrode with a British Scientific Staff of 35 aeronautical experts from the MAP and munitions experts from the Ministry of Supply. With the merger of the wartime Ministries of Aircraft Production and Supply in October 1945, scientific staff from the former were redefined as Ministry of Supply (MoS) (Air) and the latter as MoS (Munitions).
Though exploitation and the physical removal of the research equipment was a MoS (Air) responsibility, Operation ‘Surgeon’ formed part of the RAF’s remit to liquidate Germany’s air war potential, a task of the British Air Forces of Occupation (BAFO). An RAF ‘Research and Development Branch’ was established at Völkenrode, headed by an Air Commodore, to supervise the operation on behalf of the BAFO, to act as the agent in the British and Allied Zones for the MoS (Air) on all research matters and to satisfy the needs of the equipment removal operation where necessary. The operation was executed in two phases. The ‘scientific exploration’ phase commenced in late July 1945 when Professor Duncan’s team assumed control of the ‘Surgeon Stations’. Working side-by-side with German scientists, the British staff ran plant and equipment for calibration, testing and the collection of essential data. This activity was largely completed by late 1945, though a limited amount of running for special projects continued until 15 June 1946. Subsequently, the British Scientific Staff supervised monograph writing and catalogued the technical libraries. When test data had been acquired, the centre of gravity of Operation ‘Surgeon’ shifted to the ‘removal’ phase. Responsibility for dismantling, removing and re-erecting equipment in the UK lay with the MoS (Air) Director of Construction of Research Facilities (DCRF). Using technical experts from British aircraft firms, engineers and specialists from the Ministries of Works and Supply and German specialist and non-specialist labour, the DCRF organized the removal and transfer of aeronautical plant and equipment.
A crucial task of the British Scientific Staff throughout the ‘scientific exploration’ and the ‘removal’ phases was identifying suitable German scientists for employment in the UK. On 31 August 1945, the Cabinet Defence Committee had agreed that German scientists and technicians should be ‘exploited [in the UK] as fully as political and security considerations permit in the interests of defence research … in order to develop our military potential at Germany’s expense’.27 Responsibility for policy coordination lay with the DCOS Committee and the recruitment programme became known as the ‘DCOS Scheme’.
Following the resolution of acrimonious disagreements with the Americans over the ‘ownership’ of aeronautical experts at Völkenrode and Cuxhaven in late August 1945,28 Anglo-US mechanisms for the allocation and employment of German scientists were agreed.29 A ‘pool’ system was established, whereby specialists in both Zones of Occupation became available for recruitment by either country. Under the aegis of the Combined Chiefs of Staff in Washington, the DCOS Committee and its American counterpart exchanged lists of the scientists Britain and the USA required from ‘Bizonia’ on a regular basis. Inter-governmental agreement was extended to ensure ‘approximate equality of allocation’ of German experts across scientific fields and exchange of the results of work done ‘without reservation or time limit’.
Professor Duncan’s team from the MoS (Air) were a vital element of this process because it was responsible for compiling the lists that were submitted to the DCOS Committee and then on to Washington. Operation ‘Surgeon’, therefore, became the focal point where German manpower requirements for post-war British aeronautical research were defined. By November 1946, the British Scientific Staff had produced records on 500 German aeronautical experts and selected 74 for inclusion in lists for longterm employment in the UK. Scientists from the MoS (Munitions) exploiting rocket technology at Trauen were also instrumental in selecting German missile specialists who contributed to the overall total of 122 scientists in which that branch of the MAP had an interest.30
Between July 1945 and November 1946, the British Scientific Staff interrogated an array of high-grade German aeronautical experts and made their recommendations under the provisions of the DCOS Scheme. Over the same period, acute barriers hindered the translations of these recommendations into a large-scale recruitment programme. The original Defence Committee endorsement for the DCOS Scheme had explicitly restricted German recruitment ‘to that minimum who have a real contribution to make’.31 This policy to limit recruitment reflected an accumulation of security and political considerations.
In part, the strict recruitment limits reflected a perceived security dilemma: how to extract the maximum amount of knowledge the German experts could provide for the post-war military research and development (R&D) programme while at the same time reducing ‘to the absolute minimum the knowledge they [could] acquire of our own work and intentions’.32 The aspiration of the DCOS Scheme was to ‘to bring German scientists to the UK in order that their knowledge might be exploited and after we had obtained what we wanted from them, … they would be sent back to Germany’;33 correspondingly, the concern was that:
Germans who have been employed [in Britain] might, at some future date, choose to return to Germany or go elsewhere, and there can therefore be no real safeguard against leakage of defence secrets which they may acquire while working here.34
Immediately after the war, officials feared that ‘leakage’ of defence secrets could aid future German re-armament, or ‘the risk that [by employing Germans for long-term research would] keep alive a most dangerous part of the German war potential’. By 1946, this had been replaced by anxieties that British defence secrets might be passed to the Soviet Union. ‘Security considerations’ were not limited solely to fears about information leakage to potential adversaries; they also included concerns that reliance on ‘enemy aliens’ could generate critical dependencies in particular fields:
The long term risk is that they [German experts] may make themselves so useful in the defence work on which they are engaged that in an emergency we are faced with the dilemma either that a large number of key positions are held by men of doubtful loyalty, or that the war effort is adversely affected by dismissing them.35
British officials had been prepared to accept that individuals processed through the BIOS Scheme for short interrogation visits to the UK were ‘not screened first’ and may have been ‘black Nazis’.36 However, political sensitivities about the involvement of potential DCOS recruits in the wartime German regime led the Defence Committee to add the stipulation that ‘nobody whose record indicates that he was a convinced Nazi should be brought to the UK to work, however high his scientific qualifications’.37
This edict had two implications. First, it precluded any wholesale recruitment of aeronautical experts residing in the British and American Zones of Occupation. Second, as officials recognized at the time, ‘the necessity of selection of ex-enemy scientists being based largely on political considerations … [limited] … the possibility of selecting the best personnel in the technical sense’.38
Between August 1945 and November 1946, a further factor militating against a large-scale recruitment effort was Defence Committee concerns about public criticism of ‘renumerated employment of ex-enemy aliens’. This led to the decision that ‘in no cases would German experts brought to this country be employed in positions which might otherwise have been filled by British subjects’.39 Consequently, the Germans were to be entirely ‘supplementary’ to trained British scientists and there was no question of DCOS recruits displacing ‘normal’ staff.
Finally, the contracting of selected Germans through Operation ‘Surgeon’ had become the victim of bureaucratic inertia. An evident source of frustration among the British Scientific Staff at the ‘Surgeon Stations’ was that negotiations with 12 separate authorities were necessary to gain exit permits.40 By 4 October 1946, the net effect was that of the 80 specialists selected by the MoS (Air) team at the ‘Surgeon Stations’ and included in lists exchanged with the Americans, just 16 were actually employed in the UK. This reflected a more general pattern: taking the DCOS Scheme as a whole, of the 184 German scientists required by the Admiralty, MoS (Munitions) and the MoS (Air), only 35 had actually arrived in Britain.41
In December 1946, the DCOS recruitment process gained impetus. Responding to reports by the Chiefs of Staff that the Soviet Union was actively enticing specialists from the British and American Zones of Occupation, the Defence Committee agreed the need ‘to deny to the Russians those German scientists and technicians within our influence who would contribute substantially to the building up of Russian war potential’.42 This was coupled with concerns that delays in contracting the Germans already allotted to Britain on defence lists was ‘likely to cause unfavourable repercussions with [the] Americans, who under [Anglo-American] agreement are supposed to receive [the] results of research work done by British in UK and who have renounced their claims to Germans in several cases on [the] understanding [the] British would be taking them’.43
The Defence Committee’s decision in December 1946 meant that British objectives were now extended to include ‘denial’. The revised policy shared key similarities with ‘Project Paperclip’, the American equivalent of the DCOS Scheme. Whereas the original conception of the DCOS Scheme ‘had required the selection of personnel on the basis of their positive merits’ for Britain – ‘the revised plan called, in addition, for the choice of persons primarily for a negative reason – to “deny” their talents to a foreign power’.44 Measures were introduced to speed up the contracting process and the transfer of experts from the ‘Surgeon Stations’ to the UK.
The ‘denial’ imperative also led to a relaxation of the strict rule pre
cluding recruitment of ‘convinced Nazis’, and it now became ‘possible in one or two cases’ for the Admiralty and the MoS ‘to overcome the letter of the ruling by obtaining the approval of the Security Authorities to special arrangements and by reporting each case to the Minister for his personal approval’.45 In the event, the MoS did employ individuals assessed as ‘active Nazis’ during security screening, notably the rocket experts Jurgen Diederichsen and Johannes Schmidt. Both had initially been assessed as ‘unreliable’, were ‘active members of the SA, and … the SS respectively’ from 1933 to 1945 and would, it was considered, become active Nazis ‘again given the opportunity’.46 Similarly, of the 26 Germans at Völkenrode that were hurriedly offered contracts to work in Britain, ‘most had been members of the Nazi Party, but denazification was passed as a mere formality’.47
After December 1946, the contracting of German experts at the ‘Surgeon Stations’ accelerated. By mid-January 1947, of the 57 experts allotted to the MoS (Air) and still required some 30 (43 per cent) were contracted. For the DCOS Scheme as a whole, 159 scientists were allotted and still required, of whom 68 (43 per cent) had arrived in Britain.48 By the time the task of contracting DCOS recruits by the MoS (Air) was finally completed in 1948, some 87 experts had been transferred to British government defence research establishments.
In parallel, as the ‘removal phase’ was completed at the various ‘Surgeon Stations’ the establishments were gradually handed over to the British Control Commission. The Focke-Wulf laboratories at Detmold were cleared and transferred in March 1946, followed by the KWA and AVA laboratories at Göttingen and Reyerhausen in November 1946. The LFA at Trauen was cleared for disposal in January 1947 and, with the release of the LFA at Völkenrode in July 1947, Operation ‘Surgeon’ was brought to a close.
TECHNOLOGY TRANSFER AND ITS EFFECTS It is important to note that various constraints preclude any precise evaluation of the impact of Operation ‘Surgeon’ on post-war British aeronautical development. One constraint arises in attempting to trace the downstream effects of the documents and equipment acquired through the operation on post-war British development and manufacture of final weapons systems. There are also acute difficulties in producing meaningful estimates of the financial value of the Operation ‘Surgeon’ contribution to longer-term British military R&D and production. As Judt and Ciesla point out:
The main problem is to determine the ‘value’ of technical documentation … and above all, the German experts. It was possible to credit material deliveries to reparation accounts at current value, but the ‘value’ of German intellectual property acquired by means of compulsory measures did not materialize before being applied in the victorious countries in a future time.49
Consequently, ‘because one can only speculate on the value of this [knowhow] transfer’50 it is impossible to determine the precise financial worth of the technology transferred from Germany to Britain, or indeed, whether Britain extracted the maximum ‘value’ of the potential contribution that the DCOS Scheme theoretically offered.
Notwithstanding these constraints, there is evidence that Operation ‘Surgeon’ did have beneficial effects. From the ‘scientific exploration’ phase the MoS acquired what it assessed at the time to be probably ‘the finest collection of aeronautical works in the world’.51 Approximately 180 German experts had been retained to write monographs covering the detailed wartime work of the ‘Surgeon Stations’ and at Völkenrode alone some 252 complete monographs were produced. Also evacuated to Britain was the LFA library, comprising 4,900 volumes on air research and allied subjects, and an almost complete technical library on German aeronautical research from the Focke-Wulf library at Detmold totalling 3,300 separate reports.
The ‘removal phase’ and the ‘Gold Dust’ scheme – a secondary effort to gather up equipment from smaller aeronautical stations throughout the British Zone – resulted in the extraction of 14,000 shipping tons of equipment to the UK.52 As a result, Britain acquired an extensive range of highly specialized wind tunnels and equipment for investigating highvelocity flight at stratospheric altitudes. These included, from the LFA, a wind tunnel with an electric motor driving fan with an output of 14,000hp, a 400-metre firing range designed so that air density and temperature could be adjusted to high altitude conditions, a wind tunnel constructed to subject projectiles to cross winds up to 500mph and an engine test rig capable of providing the conditions of density, humidity and temperature of altitudes up to 50,000 feet. From the other ‘Surgeon Stations’, Trauen provided a liquid oxygen plant capable of producing one-and-a-half tons per day and a rocket test stand designed for a thrust of 100 tons. When the equipment was reassembled, Britain had four state-of-the-art aircraft research centres at Farnborough, Bedford, Pyestock and Fort Halstead.53
An equally significant contribution of Operation ‘Surgeon’ was the impact on British aeronautics and rocketry made by the 87 experts recruited under the DCOS Scheme. Of these, 17 experts were employed at the Rocket Propulsion Establishment (RPE), Westcott, on rocket propulsion research and a further 16 undertook missile design in the Guided Weapons Department at the Royal Aeronautical Establishment (RAE), Farnborough. Of the remainder, 54 worked at the RAE primarily in the Aero Department with smaller numbers employed in the Chemistry, Electrical, Radio and Structures departments. Included were individuals that had occupied senior positions in wartime Germany. The RAE acquired first-rate specialists including Hans Multhopp, formerly a senior aerodynamicist with Kurt Tank in the Focke-Wulf design office. Significant rocket specialists were also recruited including Johannes Schmidt, formerly in charge of the development of the Me 163B powerplant at Walterwerke; Hans Ziebland, who was one of Germany’s leading experts on heat transfer in rocket motors; and Botho Demant, who was the Chief Chemist at the Luftwaffe Peenemünde West Establishment.
The contribution to post-war British aeronautical R&D that the DCOS cohort of experts made can be divided into two discrete periods: the initial ‘exploitation’ phase between 1946 and 1950, and longer-term contributions after 1950.
Between 1946 and 1950, one crucial field where the recruits had a tangible impact was high-velocity aerodynamics work at the RAE, Farnborough. In the later stages of the war attention had been given in Britain to developing a straight-wing experimental supersonic aircraft – the Miles M52. A significant discovery that came to light in 1945 was that the Germans had appreciated the value of sweepback as a means of delaying the impact of compressibility at high subsonic speeds – a factor that had not been fully appreciated in Britain either by the aircraft industry or by the government defence research establishments. The Allied missions that entered Germany concluded that the extensive work had been conducted on the swept wing in the transonic regime appeared to suggest that the straightwing approach adopted for the M52 was a mistake, and:
When the German data became available, there was concern in the Ministry [of Supply], not least in the Department of Scientific Research and the Directorate of Technical Development. O
rders were given to cancel immediately any high-speed projects which did not incorporate sweepback.54
Wartime German aerodynamics innovations therefore had a direct impact on the direction of post-war British R&D.
The German aerodynamicists recruited through Operation ‘Surgeon’ were instrumental in advancing these innovations, notably those employed at the RAE Aero Department. An important contribution was made by the aerodynamicists Martin Winter and Hans Multhopp who, in 1948, designed an experimental 55 degree swept-wing transonic research aircraft to be powered by the Rolls-Royce AJ.65 axial flow turbojet.55 This design acted as an important precursor to RAE thinking on supersonic fighter development that ultimately led to the P.1 Lightning jet fighter aircraft. Similarly, Dr Heinz Eggink, previously at the Aerodynamics Institut Aachen and the ‘Surgeon Stations’ at Völkenrode and Göttingen, brought ‘special experience’ to RAE development of supersonic wind tunnels and was assessed by the Aero Department in 1947 as ‘carrying quite a lot of the burden of educating us in supersonic windtunnel techniques’.56
Between 1946 and 1950, the RAE concluded that the theoretical and experimental contributions made by other Aero Department recruits including Professor Adolf Busemann, Dr Karl Doetsch, Werner Pinsker, Dr Gerhard Sissingh, Dr Hans Schuh, Dr Heinz Gorges, Dr Dietrich Küchemann, Dr Johannes Weber, Professor Schlichting and Heinz Kahlert warranted their long-term retention and naturalization in the UK. Rocketry was also a field where the German scientists channelled through the ‘Surgeon Station’ at Trauen influenced the content and direction of early post-war British research. German wartime developments in themselves were the major post-war stimulus to Britain, America and the Soviet Union to adopt rockets as major propulsive devices. The DCOS Scheme led to the recruitment, inter alia, of key German wartime specialists with state-of-the-art knowledge and previous experience that was useful in itself, and many of them had wide expertise on the use of hydrogen peroxide as an oxidizer. German influence was evident in Britain’s decision to develop liquid bi-propellent rockets, using liquid oxygen, hydrogen peroxide and nitric acid as oxidizers in the development of surface-to-air missiles including Red Duster – the forerunner of the Bloodhound, Red Shoes and Seaslug missile systems.57
A noteworthy individual contribution to British rocket propulsion was made by Heinz Walder at the RAE Rocket Propulsion Department (RPD), Westcott. Walder developed the Gamma rocket engine which was assessed by the Director of the RPD in 1952 as ‘perhaps one of the most important liquid rocket advances in the last few years’ which was ‘being adopted by both firms in industry using hydrogen peroxide as oxidant’.58Walder’s work on the Gamma ‘incorporated many pioneering features’ which were a ‘major contributor to the success’ of the Black Knight missile developed by Saunders Roe.59
Between 1946 and 1950, a measure of the importance assigned to the work of the MoS DCOS recruits as a whole was the Defence Research Policy Committee’s (DRPC) assessment that ‘many of our German scientists are settling down and becoming of real value to our long term research programmes’.60
However, over the same period there were also major barriers that militated against the integration of the DCOS Germans into Britain’s military aeronautical R&D programme and exploitation of the specialist knowledge they had to offer. At the inception of the DCOS Scheme, security concerns raised by the Home Office and the Security Services led to the decision that German specialists would be employed in government defence research establishments and have only limited contact with industry. The rationale here was that:
There would be considerable risk in permitting these scientists to have access to firms engaged on highly secret defence contracts … Leakage of information on the long-term trend of secret weapons would indeed be serious.61
The government defence research establishments themselves were directed to ensure ‘that all possible steps are taken to prevent access [by German specialists] to secret material not essential for the individual’s work’. In practical terms, because the Germans were employed on research work rather than applied development linked to projects in industry, aircraft firms were denied first-hand information on practical aspects of design and manufacture. For example, after 1948, Winter and Multhopp were permitted to work on research aircraft but security concerns precluded their extensive experience being applied on the fighter derivative.62
There were also other barriers to integration. In some instances they stemmed from the political records of individual German scientists. In those ‘one or two cases’ where ‘convinced Nazis’ were employed, ‘special security arrangements’ were imposed that took ‘the form of more complete segregation … from the British staff’ at the defence research establishments, ‘both as regards working and living conditions’.63 To diffuse potential Civil Service criticisms about the employment of ‘enemy aliens’, the DCOS recruits were initially placed on six-month contracts and a specially created pay and grading system quite distinct from British staff.64 Moreover, MoS officials took the view that integration should not be encouraged because British staff ‘would probably not willingly work as assistants to Germans’.65 Finally, MoS fears about dependencies on ‘enemy aliens’ were manifested in the decision to spread the Germans over the various activities of the research establishments rather than keep them together in what were previously successful wartime teams.66 Between 1946 and 1950, these factors had two adverse implications. First, complaints by some of the Germans about their terms and conditions of employment led to various acrimonious disputes with the research establishments.67 Second, many aviation designers such as Adolf Busemann chose to leave Britain ‘complaining about the enforced isolation’.68 A measure of the impact of this perceived alienation was that by the early 1950s, 60 of the original MoS recruits had left Britain. Under the aegis of the ongoing Anglo-US ‘denial’ policy many who went secured employment in the USA: for example, concerns that Winter and Multhopp were ‘getting to know too much about the wider policy aspects of Supersonic Research at RAE’ led to American government intervention and offers of employment at the Glen Martin Aircraft Company in the USA during 1950.69
By the early 1950s, however, the barriers that had precluded integration were removed and many of those originally recruited through Operation ‘Surgeon’ remained in Britain to make a long-term contribution to aeronautical development. This shift in attitudes reflected the high value placed by senior MoS officials on the work of the German experts and their evident desire to secure long-term employment contracts for them. Deliberations about the tenure of the DCOS experts stemmed from the Director of the Royal Aircraft Establishment’s (DRAE) suggestion in October 1947 that the MoS should dispense with Germans not essential to the work at RAE and offer ‘the remainder contracts for as long a term as possible’.70
After October 1947, progress towards the aim of long-term contracts for the DCOS Germans appeared straightforward and support emerged within the MoS on the desirability of the DRAE’s proposals. By January 1948, the consensus across the MoS research establishments was firmly that the Germans were doing ‘an excellent job of work and would not be replaceable for a long time by British staff’.71 The Joint Intelligence Committee ‘saw no objection’ to extension of the contract periods for selected German scientists and the DRPC advocated that the term and conditions of DCOS experts should be brought ‘into line with those obtaining for British Staff’.72 Despite this consensus, MoS aspirations faced two formidable barriers. On the one hand, in September 1948, the Treasury pointed out that the 1919 Aliens Acts that forbade government employment of aliens, and which had been temporarily overruled when the DCOS scientists had been recruited, would return into force in December 1950.73 On the other, the MoS were also informed that any German specialists they chose to retain, and who were at that time classed as ‘supplementary’, would forthwith be counted against the establishments’ scientific staff complements.74 Confronted with these barriers, the MoS reiterated the imperative of retaining DCOS Germans on a long-term basis75 on the grounds that most were ‘doing very valuable work for us and … are irreplaceable at the moment’. Again, during March 1949, the RAE’s position remained unequivocal:
The German scientists at RAE because of their specialised knowledge and experience and the time they had been employed, had now become an essential part of the scientific complement, and their loss would be detrimental to the work being carried out. …. The original conception of the DCOS scheme, which had in mind the eventual return of aliens to their own country after having given the information which was required of them, had now changed. The aliens had become an essential part of the scientific structure of the establishments and [‘denial’ considerations meant] it was now too late to send them back.76
A measure of the momentum behind the MoS aspirations was Chancellor of the Exchequer Sir Stafford Cripps’ request to the opposition leader, Churchill,77 for cross-party agreement on a policy change to enable the naturalization of DCOS scientists. By January 1950,78 this high-level pressure led to the removal of legal impediments, and those German specialists required by the government defence research establishments were finally offered unestablished Civil Service appointments on similar terms and conditions to British staff.
After 1950, of the original 87 DCOS recruits some 27 acquired British nationality and many went on to make longer-term contributions to British aeronautics and rocket development. Understanding of the supersonic ‘narrow delta’ configuration for the Anglo-French Concorde airliner owed much to the work of the aerodynamicist Dietrich Küchemann and his associate the mathematician and aerodynamicist Johanna Weber, who were recruited by the RAE from Göttingen in 1946 and 1947 respectively. As Nahum points out, ‘Weber initiated the first interest in the aerodynamics of the narrow delta at the RAE, with a survey paper in 1955 on all the available information on this type of wing, and the configuration was first considered for its “low drag” in supersonic flight.’79 A measure of Küchemann’s overall importance was that he became the highly respected head of the RAE Aero Department from 1966 to 1971.
Another was Werner Pinsker, an expert on aircraft flight dynamics and their implications for aircraft handling and control, who joined the Aero Department in August 1947, again from Göttingen. By the early 1950s, Pinsker had ‘shown exceptional originality’ in proposing methods for dealing with undamped oscillations on high speed jet aircraft which were subsequently adopted in RAF fighter designs.80 Promoted to Senior Principal Scientific Officer in July 1967, Pinsker was ‘closely involved’ in the development of successive generations of British aircraft including the Vampire Mark 5 jet fighter, Concorde and the four-nation Tornado Multi- Role Combat Aircraft (MRCA). Before retiring in 1980, Pinsker had risen to become the UK Adviser to the MRCA Project Office on all matters relating to stability and control on the Tornado aircraft.
Of the rocket experts recruited by the RAE Guided Weapons Department, Siegfried Entres, a wartime Section Leader at the Peenemünde Research Station recruited in 1947, made a long-term contribution to British missile development and space policy. Between 1947 and 1962, his work included the design of a missile targeting computer and missile vibration research. Subsequently, he joined the RAE Space Department and spent five years with the European Space Organization. Between 1973 and his retirement in 1977, Entres was responsible for the development of UK space policy and overall planning of the British space technology programme – a task that included the coordination of the efforts of industry and government establishments. Similarly, MoS personnel records indicate that experts recruited by the RAE Rocket Propulsion Department, Westcott, including Friederich Jessen and Jurgen Diederichsen, made valuable theoretical and practical contributions to the development of liquid and solid rocket fuels and motors from the late-1940s until their retirement in the mid-1970s.
OPERATION ‘SURGEON’, DCOS RECRUITMENT AND THE HISTORIOGRAPHY OF BRITAIN’S ‘INTELLECTUAL REPARATIONS’ A mass of popular and academic literature holds that US programmes to recruit elite German scientists after World War II paved the way for the advances in aerodynamics and the rocketry that underpinned American Cold War technological dominance.81 In stark contrast, few detailed historical studies of post-war British defence science and technology acknowledge any significant input from the German experts Britain recruited. Instead, a limited and largely polemical literature on the British experience has generated a popular orthodoxy that Britain failed to exploit a technological opportunity that was harnessed so effectively by the Americans. Illustrative is Sir Roy Fedden’s assertion that: Only Britain of the wartime ‘Big Three’ victors could not be bothered to appreciate the implications of the new aeronautical techniques which Germany had assimilated in such a remarkable way. Reports of their work into inter-continental guided missiles, today greatly developed and realised in a practical form in the USSR and the US, were dismissed as a Wellsian fantasy or a Jules Verne dream by our people at home.82
The Americans, so the argument goes, could be satisfied that they had ‘captured the best’ German experts,83 whereas the scientists Britain employed were ‘too few in number’ to have any real post-war impact. This assertion is based on comparative recruitment figures: between late 1945 and 1952, the USA employed 642 German defence experts under ‘Project Overcast/Paperclip’, compared with the 172 specialists recruited through the DCOS Scheme.
Moreover, in contrast to the USA, Britain is presented as having frittered opportunity away84 because ‘few German brains were properly utilised’85 as a result of the decisions, inter alia, to limit contact the DCOS experts had with projects, and to fragment former German wartime teams. Overall, the UK’s purported failure to capitalize on Nazi German innovations is presented as a classic case of the ‘British disease’, or a more general inability to exploit technological opportunity.
Correspondingly, this critique implies a particular counter-factual history: had Britain exploited German brains more effectively then it might have developed successful gener
ations of aircraft and missiles on a par with post-war American achievements.
This popular account raises two issues. The first is why German science more generally, and the DCOS Scheme in particular, figure so little in the historiography of post-war British defence science and technology. The explanation stems in part from the fact that the US recruits received considerable public attention, particularly after the successful Soviet launch of Sputnik in 1957, which ‘gave rise to widespread currency of the quip that their Germans were better than our Germans’.86 It has also resulted from the much greater criticism, during the 1960s in particular, of the USA military industrial complex when compared to its British counterpart.87 A more significant factor, however, was relative British and American achievements in the 1940s and 1950s. On the one hand, with Cold War rearmament imperatives and access to large-scale government R&D funding, American industry succeeded in the development and manufacture of successive generations of state-of-the-art aircraft and rockets. On the other hand, a relatively small proportion of British development projects finally proceeded to production. Between 1945 and 1965, the British aircraft industry undertook 165 manned projects that were overtly intended for manufacture, of which just 10 aircraft types were eventually produced in quantities of 500 or more.88
Britain’s questionable performance reflected, inter alia, the policy of ‘parallel development’, or government sponsorship of two or three designs of aircraft in each class in order to safeguard against the failure of any one type, and budgetary constraints which were reflected in Britain’s overall adjustment from a ‘first division’ weapon producer to a leader of the ‘second division’. Consequently, as Edgerton points out, these factors conspired to create a situation where:
… much of the history of the post-war aircraft industry is the history of R&D programmes rather than the history of production aircraft. The Brabazon, the Princess, the V1000, the TSR-2, the Blue Streak, never went into production. Indeed, much of the history of post-war aviation is the history not even of R&D programmes, but of R&D policy decisions.89
Much of the acclaim surrounding the German experts recruited by the Americans reflected their involvement in ‘successful’ programmes that entered service with US armed forces. Correspondingly, the marginalization of German scientists in the historiography of British post-war aeronautics has occurred because many of the DCOS recruits were employed on development lines that ultimately failed to proceed to production for reasons that had little to do with the quality or activities of the German specialists themselves.
This study of Operation ‘Surgeon’ suggests that the DCOS aerodynamicists and rocket scientists did have an impact on the content and direction of post-war British military R&D. This implies the need for more research into the role German scientists played across the range of post-war weapon-related development, if only to augment the history of why Britain undertook the projects it did and further our understanding of how and why those projects ultimately performed the way they did.
The second issue generated by the popular orthodoxy stems from its assumptions about the ‘failure’ of British policies towards German defence scientists and technicians. There is certainly evidence that Britain might have achieved more by recruiting a larger cohort of German scientists and by integrating them more closely into the military R&D programme. For example, throughout the late-1940s, Britain encountered chronic shortages in qualified scientists and engineers (QSEs) in precisely those fields where German expertise seemed to have the most to offer.
During February 1948, the Ministry of Defence’s Defence Research Policy Committee evaluated the impact of QSE levels at the defence research establishments on development times for high-priority defence items.90 The assessment, compiled so that ‘figures for staff excluded German scientists’,91 found that 4,989 personnel in the Scientific, Engineering and Experimental grades were needed to meet stated commitments, whereas actual manpower was over 1,400 staff short. The QSE shortfalls were most acute in the aeronautical and guided weapons sectors with the implication that:
… so far as completion dates are concerned … there will be delays extending up to at least four years on various items. Certain vital Radar equipment, Guided Weapons and AA [anti-aircraft] equipments are among the most seriously affected. Lack of suitable staff in the aeronautical field will affect the efficiency of new aircraft and will lead to delays in reaching higher speeds.92
More might also have been achieved had Britain followed the US armed services in preserving wartime teams or encouraging greater contact between German experts and aircraft manufacturers. In the British case, the majority of the DCOS recruits had left by 1950, many complaining of enforced isolation. By contrast, retention rates were much higher in the US where German wartime teams were fostered and maintained, to the extent that some 90 per cent of ‘Project Paperclip’ recruits elected to remain in America after 1950.93 Similarly, evidence suggests that US Air Force policies which actively encouraged collaboration between German recruits and aircraft contractors provided significant benefits for the American military aircraft programme; potential gains that the British armed services may have sacrificed by keeping the DCOS Germans isolated from applied development connected with projects in industry.
Correspondingly, however, there is evidence that the popular orthodoxy underrates the performance of British policies in three respects. First, the application of hindsight has tended to downplay the constraints on German recruitment that arose from the social and political milieu in which British policy was formulated. Anxieties expressed by the Defence Committee in 1945 about the security implications of employing ‘enemy aliens’ in the defence field, fears of ‘German dominance’, the political ramifications of employing ‘convinced Nazis’ and potential labour relations problems at the defence research establishments all acted as understandable barriers to recruitment and integration in the late 1940s. In this light, British policy can be interpreted as a logical response to the prevailing social and political conditions of the time.
Second, it is a gross oversimplification to say, as the orthodoxy implies, that Britain was somehow denied access by the Americans to the elite scientists it required. Between December 1945 and July 1949, under the inter-governmental agreements implemented by the Combined Chiefs of Staff in Washington, the UK and the US exchanged 35 lists of German scientists required for defence work.94 The UK lists comprised 381 individuals of whom 172 were recruited for the MoS and Admiralty research establishments. Of the 209 German scientists included in British lists but not ultimately employed, some 188 were categorized as ‘no longer required’ after subsequent enquiries revealed that long-term employment was not necessary.
Consequently, when manpower requirements are subjected to closer scrutiny they reveal that Britain either employed or screened all but 21 of the German scientists and technicians listed as required by the defence research establishments. In cases where Britain and the USA required the same individual, the records show that allocations were made i
n accordance with the equity principle agreed by the Combined Chiefs of Staff, so Britain does not appear to have been disadvantaged where competing claims for particular German experts emerged.
Third, the emphasis in the orthodoxy on Britain’s purported failure to exploit German know-how tends to oversimplify the objectives
of UK policy. In addition to long-term exploitation of German experts through the DCOS Scheme, British policy included two other equally important objectives: the coordination of efforts with the Americans to ‘deny’ German experts to the Soviet Union and the fostering of Anglo-US exchange of the results derived from German scientists employed by both countries. The US military’s solution to ‘denial’ was large-scale recruitment of German experts for work in America under ‘Project Paperclip’; an approach made possible because the large-scale post-war American defence programme could absorb German manpower, and because the US military successfully conspired to hide from policy-makers the unpalatable Nazi pasts of many Germans they recruited.95
Britain’s contribution to ‘denial’ focused on the containment of defence scientists in Germany under a scheme codenamed Operation ‘Match Box’: an approach intended in part to keep ‘convinced Nazis’ at arm’s length.96 The existence of Operation ‘Match Box’ suggests, therefore, that any assessment of the impact on post-war security of British policies needs to be extended beyond that subset of scientists employed in the UK under the DCOS Scheme to encompass the performance of its ‘denial’ aspects. British policies also need to be evaluated in terms of the security benefits provided through post-war Anglo-US cooperation on information from German scientists. Evidence suggests that the ‘special relationship’ was enhanced by collaborative policies towards German specialists and that the pooling of information provided benefits for both countries. By late 1945, the British Chiefs of Staff had recognized that British long-term security interests were best served by preserving close technical cooperation with the USA and the ‘interchange’ of results was identified as an essential ‘part of general Anglo-American co-operation in the technical field’.97
After 1945, as the wartime alliance fragmented, substantial ‘underground’ Anglo-American defence cooperation continued, driven partly by the mutual imperative to coordinate policies on exploitation of German know-how, under the aegis of the Combined Chiefs in Washington. A specific aspiration of the British Chiefs of Staff after September 1945 was that ‘all results of work done by German scientists and technicians [employed in Britain and the United States] should be exchanged without reservation or time limit’.98 By early 1946, what was to become a longstanding transatlantic flow of reports on the exploitation of German scientists in Britain and America had commenced.99 The information exchange arrangements codified in the immediate post-war period also appear to have had downstream effects. For example, Britain gave information derived in the early 1950s on German wartime advances on radar absorbent material to the USA that proved to be an important precursor to the development of Stealth technology. Britain’s reward came in the early 1980s in the form of valuable American data derived from this know-how.100
Consequently, collaboration on the German science question, coupled with broader scientific, technical and intelligence information exchange, seems to have assisted British Cold War security interests by enhancing transatlantic defence and intelligence links.101
In conclusion, there is an orthodoxy arising from a small number of polemical studies which has reflected Fedden’s assertion that: The lesson of the research facilities discovered in Germany at the end of the war and their indications of the patterns of future technical development, far in advance of our own conception at the time, went largely unheeded by government and industry alike.102
This analysis of Operation ‘Surgeon’ and associated policies to exploit German aeronautical equipment and expertise suggests that Britain gained considerably more than this orthodoxy is prepared to acknowledge. Moreover, it points to the need for more research into the impact of British policies towards German scientists, above and beyond the cohort recruited for work in the UK, on wider Cold War national security interests. In this regard, the evidence indicates that Operation ‘Surgeon’ and similar initiatives should remain anything but a marginal sideline in the history of British post-war defence science and technology policy.
