Scientific director of the USSR's second nuclear weapons design centre
"The best way to avoid a problem is to ask your superior for permission. Nine times out of ten you'll get a 'no.' So if you really want to solve it, decide yourself and then report. It's rarely overturned."
A key designer in Soviet nuclear weapons physics, he served as scientific director of the second nuclear weapons design centre (VNIITF, Chelyabinsk-70) from 1960 until his death. His 1947 dissertation on converging shock waves brought him into the atomic bomb project; he contributed to the first Soviet nuclear test (RDS-1) and provided the theoretical basis for the first fully original Soviet charge (RDS-2). In 1955 he moved to the newly created Ural centre as head of theory, leading development of the first weaponized thermonuclear charge adopted by the Soviet Army in 1957. Over 25 years VNIITF under his leadership designed the majority of Soviet nuclear warheads. He pioneered peaceful nuclear explosion technologies and in his final years received the Keldysh Gold Medal for his work on unlimited cumulation.

Korolev's successor who delivered Soyuz and Salyut, and bore the N-1 lunar failure
14 January 1966: Korolev died on the operating table. The Kremlin phoned Mishin—by nightfall he carried the Soviet space programme.
Born in a peat-cutting settlement outside Moscow, he started as a fitter's apprentice at TsAGI. In 1945 he met Korolev while studying the V-2 in Germany, and served as his first deputy for two decades. After Korolev's death in 1966 he became Chief Designer of OKB-1 (TsKBEM), delivering the Soyuz spacecraft, the Salyut orbital station, and the N-1 lunar rocket. All four N-1 launches failed, and a 1974 letter from senior colleagues to the Central Committee ended both his tenure and the Soviet moonshot. He spent the next three decades as a professor at the Moscow Aviation Institute, writing the textbooks that trained generations of rocket engineers.

The long-hidden manager of crewed spaceflight
On April 12, 1961, Yuri Gagarin slept soundly before humanity's first spaceflight. Kerimov, monitoring the cosmonaut's sleep via bed sensors, spent a far more anxious night than the man about to ride the rocket.
His career began in World War II inspecting Katyusha rockets and gathering intelligence on the German V-2. He served on the State Commissions for Sputnik 1 and the Vostok programme, then chaired the State Commission for crewed flights from 1966 to 1991, twenty-five years in which he gave the final launch approval for every Soviet crewed mission. He was the administrative gatekeeper of Soviet crewed spaceflight's golden age, from Salyut and Soyuz-Apollo to Mir, yet his identity was kept strictly secret until perestroika.

Founder of CEMI and architect of SOFE: the mathematician who tried to redesign the planned economy
Late 1960s: CEMI forecast Soviet growth would slow. Gosplan's chairman refused to send it to the Politburo. To avoid charges of 'ideological heresy,' the authors burned the report on a bonfire in Moscow's Neskuchny Garden.
The economist who institutionalized mathematical optimization in Soviet central planning. Appointed in 1963 on Nemchinov's recommendation as CEMI's first director, he led it for 22 years and built the theoretical foundations of SOFE, extending Kantorovich's linear programming into a nationwide planning architecture. As Academician-Secretary of the Economics Department (1971–1986), he elevated mathematical economics to an official agenda of Soviet economic science and served as scientific director of Gosplan's Automated System of Planned Calculations.

Soviet military scientist who designed the world's first operational anti-ballistic missile defense system
A few hours before his death, he told his wife: "I need to call the guys. I solved the problem — the one they gave me."
Soviet radiophysicist and pioneer of missile defense. After contributing to the S-25 Berkut and S-75 surface-to-air missile systems, he became Chief Designer of System A in 1956, the world's first operational anti-ballistic missile defense, and on March 4, 1961, achieved history's first successful intercept of a ballistic missile in flight. As General Designer of the A-35 and A-35M systems defending Moscow, he established the Soviet Union's strategic defensive edge, earning the Lenin Prize and the title Hero of Socialist Labor. In 1975, however, he was removed from his post amid conflicts with the leadership of the Ministry of Radio Industry, never seeing his system's final modernization through; in retirement he wrote his memoir Secret Zone, testifying to a body of work that history had nearly buried.

Korolev's key partner in shaping the R-7's packet design
On 21 August 1957, the R-7 whose design Kryukov helped shape finally completed its planned flight.
Sergei Kryukov was a Soviet rocket and space-technology designer who helped define the R-7's overall form and its packet arrangement of four strap-on blocks around a central stage. If Korolev directed the programme as chief designer, Kryukov turned its concept into an integrated structure and working design through the project department he led. He later directed automated interplanetary-station and launch-vehicle work at the Lavochkin bureau and Energia. His career shows that the space programme was built not by a lone genius but by specialised collective design and production systems.

A Soviet nuclear physicist from Kharkov University. Demobilized after being wounded at the front, he joined Kurchatov's Laboratory No. 2 in 1944, where he carried out radiation dosimetry measurements and gamma-ray shielding experiments during the assembly of the F-1 reactor, built neutron counters from scratch, and performed the plutonium accumulation calculations. He was one of the handful who remained in the control room when F-1 went critical on 25 December 1946; he went on to found the Soviet reactor radiation safety system and directed the physical startups of the Obninsk nuclear power plant (1954) and the Mayak plutonium production reactors.

Korolev's right hand who led the R-7 through design, mass production, and every successive variant
The 24-year-old lieutenant who lost his left arm in the fighting north of Vyborg in July 1944 was, thirteen years later, the lead designer of the world's first intercontinental ballistic missile, the R-7.
Appointed by Korolev as lead designer of the R-7, he directed the design of the 'Semyorka' and was then dispatched to Kuibyshev (Samara) to organize serial production of the R-7 family at the aviation plant there. In 1974 he founded the Central Specialized Design Bureau (TsSKB), spun off from OKB-1, as its first head and general designer, developing the Vostok, Molniya, and Soyuz launchers alongside reconnaissance and scientific satellite families. Across design, mass production, and successive variants of the R-7, his life's work built the spine of space transport from Sputnik to the Soyuz rockets of today.

The small-arms designer who became the face of Soviet defence industry: father of the AK-47
Six months before his death, to the Russian Orthodox Patriarch: "If my rifle claimed people's lives, can it be that I … a Christian and an Orthodox believer, was to blame for their deaths?"
The Soviet Union's defining small-arms designer and one of history's most consequential weapons engineers. Born into a kulak-deported peasant family, self-taught, Kalashnikov turned soldiers' frustration with unreliable rifles into the AK-47, adopted in 1949. It grew into a family (AKM, RPK, PK, AK-74) whose simplicity and low cost made it the most distributed infantry weapon on earth. He spent his postwar career at Izhevsk Machine-Building Plant, rising from sergeant to lieutenant general and serving six terms in the Supreme Soviet. Twice a Hero of Socialist Labour and winner of the Stalin, Lenin, and State prizes, he embodied Soviet military-industrial technocracy: a state-honoured designer who never grew rich. In old age he wrote the Orthodox Patriarch of his spiritual pain over the deaths his weapons caused, while insisting the AK was a weapon of defence.

Father of the Soviet hydrogen bomb and the conscience who laid its privileges down. His decisive break came through the secret letter of 21 July 1967 opposing ABM deployment and the essay "Reflections on Progress, Peaceful Coexistence, and Intellectual Freedom", completed in May 1968 and circulated in samizdat, after which he was removed from weapons research; he denounced the Soviet entry into Czechoslovakia that August.

Physicist from Sakharov's group who became the lead declassifier and historian of the Soviet H-bomb project
Against the mystery of the 'Third Idea' that Sakharov himself left ambiguous, Goncharov concluded that its seed lay in Klaus Fuchs's 1948 report.
A Soviet nuclear physicist who began his career in Sakharov's theoretical department, Goncharov participated directly in the development of the RDS-6s (1953), RDS-37 (1955), and Tsar Bomba (1961), and proposed a new design direction for megaton-class thermonuclear charges. In the late Cold War, as the lead declassifier of Soviet nuclear archives under Yeltsin, he compiled the multivolume 'USSR Atomic Project: Documents and Materials' and published key papers analyzing Klaus Fuchs's 1948 report and the origins of the 'Third Idea,' placing himself at the center of the historiographical debate. His archival work provided the empirical foundation for arguments over whether the 1955 radiation implosion design was an indigenous achievement or aided by espionage.
Soviet cosmonaut who flew humanity's first multi-day spaceflight aboard Vostok 3
The moment Vostok 3 reached orbit, Nikolayev unstrapped himself and floated free inside the cabin: Gagarin had not done it, nor had Titov. It was the first time a human being had ever slipped free of gravity's hold in space.
Born to a Chuvash peasant family, Nikolayev became the third Soviet cosmonaut in space. In August 1962, aboard Vostok 3, he orbited Earth 64 times over four days, humanity's first multi-day spaceflight, and his joint flight with Pavel Popovich's Vostok 4 established the dual-launch precedent later used for the women's space mission. His flight data proved that missions exceeding three days were feasible. In 1970, his 18-day Soyuz 9 mission with Vitaly Sevastyanov revealed the severe physiological toll of prolonged weightlessness, the 'Nikolayev effect', while his 1963 marriage to Valentina Tereshkova, presided over by Khrushchev, became a signature Cold War propaganda spectacle.
