On May 22, Section 1 replied with a letter drafted by Zanssen and approved by the Chief of Army Ordnance. It endorsed the feasibility of a joint rocket aircraft program but expressed great reluctance about revealing anything at all to Junkers. Ordnance ruled out working with the Winkler group altogether for secrecy reasons, because the primary application of the rocket was the “liquid-fuel long-range missile,” a revolutionary weapon that could achieve its greatest psychological impact through sudden deployment. “A considerable development lead over foreign countries has been achieved here, the loss of which is regarded as intolerable, above all because of the value to national defense of the moment of surprise.”9
A little over a month later, the ballistics and munitions section and the Technical Office held a major meeting to work out the terms of the alliance. Professor Otto Mader, Junkers Engine Company’s development chief, also attended. For that June 27 meeting at Kummersdorf, twenty-three-year-old Wernher von Braun wrote an official position paper that must be regarded as Peenemünde’s birth certificate. Because a rocket engine differed little according to its application, he stated, it is “therefore advantageous that in the future as well, the development of the free-flying liquid-fuel rocket and the aircraft rocket engine could be carried out by the same center. Section 1 believes that this goal can be achieved through the future creation of an ‘experimental rocket establishment’.” This center should have some air force personnel, but they would be transferred to the employment of the Army or the center.10
Von Braun went on to raise a second reason why the rocket group was reluctant to become involved with private corporations:
Because the previous development of liquid-fuel rocket propulsion has been financed by the state, Section 1 continues to place decisive importance on an agreement that drawings and design documentation of all sorts grounded in that experience not be made available to industry. Otherwise there is the danger that profit-making opportunities in industry would arise from development the state has carried out at a considerable expense.11
Not only military secrecy was at issue; working with an aircraft firm raised the specter of the commercial exploitation of rocket technology, for example, through the construction of takeoff-assist rockets for heavily loaded airplanes, one of the goals of Winkler’s work at Junkers. But that would contradict the direction in which the Ordnance group was going: toward a large, secretive military laboratory in which corporations were only subcontractors.
Von Braun’s misgivings about a corporate role in the rocket program not only reflected the attitudes of his superiors; it also accorded with the rather empty anticapitalist rhetoric of National Socialism. But von Braun did not join the Party until asked to do so in 1937, and although he and the officers in the program showed every sign of enthusiastically embracing Hitler’s rearmament and “national regeneration,” none shows any sign of having been a Nazi ideologue. Ordnance’s construction of an empire of Army-owned munitions factories during the Third Reich drew less on National Socialist ideology than on centuries-old traditions of state ownership in Prussia and Germany. Ultimately, however, the obsession with secrecy and surprise and the distrust of the independent groups and inventors were the crucial factors in the rocket group’s desire to restrict corporate access to the technology. Secrecy and von Braun’s success at Kummersdorf had launched the Army firmly down the path of in-house development.12
As von Richthofen pointed out at the June 27 meeting, Ordnance’s restrictive conditions would effectively obstruct cooperation with an aircraft firm like Junkers. Nor would the Luftwaffe accept junior-partner status in any joint “experimental rocket establishment.” That statement did not, however, undermine the friendly tone of the meeting. Von Richthofen then sketched his rocket interceptor concept: an aircraft that could, after a forty-five-second boost, coast up to 15,000 meters (50,000 feet) and then glide or cruise at high altitude for some minutes. As a preliminary step, a small experimental rocket plane could be tested, perhaps by towing it into the air and igniting the engine. The projected contractor was Junkers, he announced; von Richthofen had earlier cleared this arrangement with the company representative, Professor Mader.13
During the summer of 1935 the Air Ministry brought a second large firm into the program, Ernst Heinkel Aircraft. Its owner and namesake was fascinated by high-speed flight. The Ministry may also have wished to mollify him after his company lost the single-engine fighter competition of that year. In September Ordnance, the Technical Office, Junkers, and Heinkel signed a joint agreement protecting the secrecy of Ordnance rocket development. Only five or six people at each firm were to receive access to the plans and documents, and they were to work on rocket aircraft in closed shops. Winkler’s name was conspicuously absent from the list of Junkers employees inside the charmed circle. Sometime after late October the Kummersdorf group received a Junkers “Junior” single-engine light plane and experimented with the installation of a 300-kg-thrust A-2-type rocket in the tail. The funding and arrangements for the tests were made through the Research Division of the Technical Office in collaboration with the quasi-governmental German Experimental Establishment for Aviation in Berlin. The experiments aimed at developing takeoff-assist rockets for overloaded bombers as well as gaining experience in rocket-plane work. For unknown reasons the Junkers firm itself dropped out of the picture in the fall of 1935.14
Ernst Heinkel’s firm thus became the sole aircraft contractor. On October 16, 1935, at Heinkel’s plant near Rostock on the Baltic coast, Wernher von Braun, Walter Riedel, and two Air Ministry engineers met company managers, including the short, bald, bespectacled owner himself. They discussed how Ordnance’s rocket technology might be accommodated in an aircraft.15 The eventual decision was to proceed with an interim project before the construction of a pure rocket aircraft. A rocket engine would be installed in the tail of a Heinkel He 112 single-engine fighter, the loser to the soon-to-be-famous Messerschmitt Bf 109 in the 1935 competition. In December the firm specified an engine thrust of 1,000 kg, which became the Kummersdorf “4B” series of motors. (The variants of the 1,500-kg engine for the ongoing A-3 project formed the “3B” series.) During the same month von Braun requested 200,000 marks from the Air Ministry for “Project 112 R,” noting that speed was of the essence since the work had already begun.16
By the end of 1935, then, both the Junkers Junior and the He 112 projects had been launched as part of the new Army-Luftwaffe alliance in rocketry. But the most important product of this alliance was yet to come. Shortly after New Year’s Day 1936, von Braun’s concept of an “experimental rocket establishment” would bear fruit.
