FOBS Chronology


16 March 1961 UR-200 (8K81) launch vehicle development authorised. Launch Vehicle: UR-200.

An enabling decree was issued on 1 August 1961 by the Central Committee and Politburo. The UR-200 was designed not only to send a thermonuclear warhead over a range of 12,000 km, but also to orbit all of the Kosmoplan military variants: the IS ASAT; the US nuclear-powered naval intelligence satellite; and the Kosmoplan combat re-entry vehicle.


31 August 1961 FOBS threat.

U.S.S.R. announced policy of resumption of nuclear weapon testing which had been suspended March 31, 1958, and that bombs can be delivered anywhere in the world by "powerful rockets like those Majs. Yuri Gagarin and Gherman Titov rode to begin their unrivaled space flights around the Earth."


13 October 1964 Khrushchev ousted from power. Launch Vehicle: UR-200, Proton 8K82K.

Brezhnev faction assumes control of Politubro. Brezhnev was adverse to all projects Khrushchev had supported. These included those of Chelomei and his OKB-52.


24 August 1965 Development of R-36-O and Tsyklon launch vehicles authorised Launch Vehicle: R-36-O, Tsyklon, Tsyklon 2, UR-200.

Decree 'On Creation of an R-36 Based Carrier Rocket for Launching the IS and US KA--start of work on an R-36-based launch vehicle for the IS and US programs' was issued. After Khrushchev was ousted from power, Chelomei's projects were examined by an expert commission under M V Keldysh. It was found that Yangelís R-36 rocket was superior to Chelomeiís UR-200. The UR-200 was cancelled; the IS and US satellites would be launched by the R-36 11K67. The Tsyklon 2 definitive operational version replaced the 11K67 launch vehicle from 1969.
