Part I Post #2: Spoils of War
In 1945, with Allied armies pressing from all sides, the most technologically advanced rocket programme in the world was to be found in the rubble-filled husk of Hitler’s broken Reich. In the last six months of the war, prioritised by a desperate leadership and manufactured using slave labour, over 3 000 V-2 missiles were fired by German forces. Despite the rocket’s high failure rate, it was still an incredible feat for a nation on its knees. As soon as victory was won, the Allied powers set out to find the men who had made this possible.
Following an initial political struggle in Moscow, responsibility for the development of Soviet rocket technology had been assigned to the Ministry of Armaments under Central Committee member Dimitry Ustinov. Unlike many of his contemporaries, Ustinov saw rockets as the weapon of the future, especially if used to carry the atomic bombs currently being developed under the direction of Lavrentiy Beria. In a secret directive approved by Stalin in May 1946, a network of research institutions was established under Ustinov’s control with the objective of systematically exploiting the captured German rocket technology for the benefit of the Soviet military.
The lead institute, NII-88 (the Russian acronym for “Scientific-Research Institute No.88”), was to be the central institute responsible for rocket designs, with an initial focus on developing Soviet versions of the V-2, Wasserfall, Schmetterling and Rheintochter missiles. Another institute, OKB-456 (“R&D Institute No.456”) , would focus on rocket engine development, reproducing and then exceeding the V-2 engine capabilities. Additional institutions were established for guidance and control systems (NII-885), gyroscopes (NII-10), and launch equipment (GSKB). Together, these institutes would allow the development of a complete range of ballistic, cruise and ground-to-air missiles for the defence of the Motherland.
The May 1946 decree also affected the future of the Soviet specialists then working at Bleicherode in occupied Germany, with many promoted to leadership positions in the new institutions. Valentin Glushko was assigned to be Chief Designer of OKB-456 in Khimki, whilst Vasily Mishin was assigned to NII-88, working under Chief Designer Yevgeny Sinilshchikov. The decree also ordered that the German rocket scientists who were working with the Soviets in Bleicherode, led by Helmut Gröttrup, be relocated to the USSR at the earliest opportunity. The purpose of this was not so much to have the Germans design Soviet weapons, but rather to pass their knowledge and expertise on to Soviet workers, with the aim of eventually ending the USSR’s reliance on the German specialists.

The first priority for the Soviet Union’s rocket scientists was to reproduce a domestic version of Germany’s V-2 rocket. Many of the scientists and engineers involved, eager to try out their own new ideas, saw this approach as a pointless waste of time. After all, despite being an impressive technological achievement for the time, in combat the V-2 had proven itself to be militarily useless. Far from turning the Allied tide, Hitler’s “wonder weapon” had if anything accelerated the Third Reich’s downfall by diverting critical resources from conventional forces. What was needed were larger, longer ranged rockets capable of carrying the future Soviet atom bomb direct to enemy cities, not a puny V-2 clone.
Ustinov disagreed. The USSR had been devastated by the war, both in terms of physical destruction and in the loss of a generation of workers to the front. Moreover (though he would never raise this point in public), the purges of the pre-war years had decimated the ranks of the nation’s brightest and best. Ustinov realised that the USSR of 1946 simply didn’t have the industrial or intellectual capacity to design and build all-new rockets from scratch. Far better, in his opinion, to use the captured and re-created V-2 plans as a starting point to train a new cadre of technicians, engineers and specialists in rocket production, and only then taking the next step to a fully domestic rocket. Studies could and would be started into designs for potential longer ranged rockets, but the R-1 (the designation given to the Soviet version of V-2) would be the priority.
Work proceeded rapidly, and the first launches of the N-series V-2s that had been built with German components in Bleicherode took place from the new test range at Kasputin Yar in October 1947. The first launch attempts failed due to faulty wiring, and a team of Gröttrup's specialists were brought out to the site to help fix the problems. Even with their assistance (or perhaps, as some darkly alluded, because of their sabotage), many of the rockets veered off course, exploded, or otherwise failed. Given that the operational reliability of the V-2 had never been much more than 50% this was perhaps unsurprising, but it did nothing to convince people like Glushko or Mishin that they had anything left to learn from the Germans. Many in the military and political hierarchy agreed, and the Germans found themselves increasingly isolated, with Soviet plans to duplicate the V-2 kept secret from them.
Despite this widespread distrust and disdain for the Germans’ contributions, the experiences of next year seemed to validate Ustinov’s view of the lack of readiness of Soviet industry to support missile production. In building the R-1, Sinilshchikov’s team faced daunting problems, ranging from the duplication of delicate guidance instrumentation to the more basic problem of simply sourcing the numerous specialist grades of steels and synthetics needed from Soviet industry. Entire chemical and metallurgical factories were handed over to NII-88 control in order to create local substitutes for German materials, and the most prestigious Soviet scientific institutes were instructed to provide the rocket industry with support in radar technology and aerodynamics. Only Beria’s atom bomb project received a higher priority from the State.
By November 1948, Sinilshchikov was ready to begin flight tests of the R-1. The extra experience gained and greater understanding of the systems meant that the R-1 tests went far better than the V-2 launches had, with only two of the eight missiles failing. A second test campaign in 1949 went even better, confirming the missile’s range at 280 km, and the R-1 quickly entered into full production for operational deployment. Regardless of the statistics from the R-1’s test campaigns, its main purpose, that of training up the Soviets in missile development, had been a complete success.
Underutilised by the Chief Designers, when the captured German specialists were given substantial work they applied themselves with vigour. In May 1947 Gröttrup's group were given the task of designing a rocket with a range of 600 km. Designated G-1, the intention was to use the German design as a benchmark against which to assess a design proposed by NII-88 to meet the same specification. When the designs were compared in December 1948, Gröttrup's G-1 was found superior to Sinilshchikov’s R-2. A similar competition in June 1949 for a multi-stage missile able to launch a 3 tonne warhead over 3 000 km again saw Gröttrup's design, the G-4, preferred to Sinilshchikov’s R-3.
Despite these apparent victories for the German team, they were still denied access to experimental equipment, and so had no hope of developing their designs any further. Instead, aspects of Gröttrup's rockets were incorporated into Sinilshchikov’s designs. The R-2, now a Gröttrup-inspired cylindrical shape rather than Sinilshchikov’s original ogive, began state trial flights in September 1949, and was accepted into military service in 1951. The R-3A technology demonstrator incorporated numerous aspects from the G-4, including the distinctive sloped first stage. By the beginning of 1951 the Germans had been almost completely isolated from the real work of the Soviet rocket programme, and by the end of 1953 all had been repatriated to East Germany.
Although progress was being made, Ustinov and his deputies weren’t entirely happy with the output of NII-88. The relative poor quality of the original R-2 and R-3 design submissions had been bad enough, but there was also a palpable discontent with Sinilshchikov’s management style amongst the workforce, as well as friction between the NII-88 Chief Designer and his counterparts at other institutes. Finally in May 1952, following slow progress on development of an ICBM, a major restructuring of NII-88 was proposed. OKB-1 was created within NII-88 with its focus purely on land-based long range ballistic missiles. Sinilshchikov would remain as Chief Designer of OKB-1, but all responsibility for ground-to-air, cruise and naval missiles would be removed to other departments. Additionally, Mikhail Yangel was appointed as the institute’s Director, and therefore as the immediate superior of Sinilshchikov, with instructions to whip OKB-1 into shape and get the ICBM project back on track. However, at first it was far from clear if this change of leadership was a good idea.
Yangel had joined NII-88 from the aviation industry in April 1950 as head of the the guidance systems section. Despite some initial friction with Sinilshchikov (not uncommon amongst the Chief Designer’s subordinates), Yangel soon developed a productive working relationship, and became heavily involved in the re-assessment of NII-88’s design approach following the shortcomings exposed in comparison to Groettrup’s designs. During the course of his work on the R-5, R-11 and R-12 draft projects, Yangel became convinced that the kerosene-oxygen propellants being proposed by NII-88 were not well suited for military purposes. Although giving good performance, they were bulky and posed severe difficulties in maintaining the launch readiness at short notice needed by the military. Glushko had been experiencing his own problems in attempting to scale up kerolox engines for their rocket designs (the failure of his RD-110 being one of the main issues with the original R-3 design), and this reinforced Yangel’s impression that “high boiling point” storable, hypergolic propellants, that could be pumped around without complex insulation and kept on-station in their rockets’ tanks for weeks at a time, would be a much better fit to the military’s needs. Indeed, such propellants were already being successfully used in the smaller ground-to-air, air-to-air and naval missiles coming from other design bureaux.
When a decree in December 1950 authorised a project for the "Development requirements for a liquid rocket with a range of 5 000 to 10 000 km and a warhead of 1 to 10 tonnes", the initial expectation was that this would be a scaled-up hydrocarbon-liquid oxygen rocket along the lines of the R-1, 2 and 3 proposals. However, as the draft projects proceded over the following year, Yangel started to push for a storable propellant solution. Sinilshchikov was willing to listen to Yangel’s approach, but the proposal faced strong internal dissent within NII-88, led by Vasili Mishin. Mishin and his supporters argued that not only were the storable propellants extremely toxic, but they also had a considerably lower theoretical performance than kerolox. Even at this early point, Mishin had one eye on an eventual space launcher, and he knew that every second of specific impulse would be crucial in orbiting a useful payload. Additionally, all of NII-88’s experience for large ballistic missiles up to then had been with liquid oxygen/hydrocarbon vehicles. Proposing the new storable approach on their largest missile yet would be to throw away the knowledge gained so painfully on earlier projects.
The debate raged within NII-88 and between the Chief Designers and their staffs for the next one and a half years until finally, tipped by Yangel’s newfound influence as OKB-1 Director from 1952 onwards, Sinilshchikov selected the storable propellant option. The former artillery man did not have the same romantic vision for future spaceflight as Mishin, and following his recent dressing-down from the leadership he wasn’t prepared to risk producing a sub-standard ICBM in the hope that it could one day send men into orbit. At Yangel’s suggestion a compromise was reached whereby Mishin was put in charge of a team that would continue to study kerolox rockets as a potential fall-back option should the preferred design prove to be unfeasible, but the draft concept of the R-6 missile for presentation to the Council of Ministers would be fueled with storable propellants.
Despite the time lost to the propellant debates and the leadership shake-up, the R-6 requirements project was completed and a proposal for further development ready for presentation by the end of February 1953. But just as it was due for discussion by the Council of Ministers, Joseph Stalin died. All other government and Party business was put on hold as various factions began the drawn-out and highly dangerous process of choosing a successor to the dead dictator. When the initial dust had settled, Georgy Malenkov was the new Chairman of the Council of Ministers (and so
de jure head of the Soviet government), whilst Nikita Khrushchev was elevated to the re-created role of General Secretary of the Communist Party’s Central Committee (head of the Party, and therefore the
de facto leader of the nation). Dimtry Ustinov, who had been such an active patron of Soviet rocketry, remained on the Central Committee, and even saw his role in government expanded as the Armaments Ministry and Aviation Ministry were consolidated under him in the Ministry of Defence Industry.
Following this reorganisation of the Soviet government, a decree was issued in December 1953 authorising the start of development on a slew of rocket programmes, including the R-5, R-11, R-12 and R-6 missiles. At the same time, at Khrushchev’s insistence, it was decided that a new, autonomous rocket development institute should be created in the Ukrainian SSR to ensure that in the event of a nuclear strike on Moscow, the USSR would still retain an effective missile industrial capability at a separate location. Following his success as Director of NII-88, Yangel was quickly chosen to be Chief Designer of the new OKB-586, charged with development of the R-12 MRBM. Development of the Soviet Union’s first Intercontinental Ballistic Missile, the R-6, would remain with Sinilshchikov at OKB-1. It would not be an easy job.
As soon as the end 1953 it was realised that the 3 tonne warhead initially specified for the R-6 (or “Article 8K61” as it was referred to in all official documentation) would be insufficient. The USSR had exploded its first atom bomb in 1949, and it was hoped that this would soon be followed by a thermonuclear “Hydrogen” bomb, but despite these efforts to catch up with the US, Soviet bombs remained for the time being cruder and heavier than their American counterparts. The R-6 would have to deliver a payload of at least 5.5 tonnes to be an effective weapon of war. Fortunately, this change of requirements occurred early enough in the programme that adaptations were manageable, and the basic design of the R-6 was completed in October 1954. The missile was to be a two-stage design, with both stages using Sinilshchikov’s favoured nitric acid/UDMH propellants rather than Gröttrup's kerosene and liquid oxygen. The first stage would be powered by four of Glushko’s twin-chambered RD-215 engines working in parallel, with the second stage using a altitude-optimised engine dubbed RD-221. This combination would be more than capable of delivering the heavy warhead over 8 000 km. It was on the basis of this concept that development of the R-6 was authorised in January 1955. However, there was one more external factor that would significantly affect the R-6 project.
In 1950, the International Council of Scientific Unions had declared that the period from 1st July 1957 to 31st December 1958 would be designated as the International Geophysical Year. Modelled on the earlier International Polar Years of 1882-83 and 1932-33, the IGY was intended to encourage East-West scientific cooperation in various fields of Earth sciences. Plans proceded throughout the early fifties, propelled by a strange mixture of cooperation and one-upmanship between the two Superpowers, with each side seeing it as an opportunity to demonstrate that they, not their Cold War opponent, were the leading scientific nation of the world. The pinnacle of this competition came in July 1955 when the Eisenhower administration announced plans to launch Earth orbiting satellites during the IGY. Not to be outdone, just a few days later the Soviet government announced that they too would soon launch a satellite. With that announcement, the Space Race was on.
