Tsyklon 2 Chronology 1965 August 24 - Launch Vehicle: R-36-O, Tsyklon, Tsyklon 2, UR-200. - Development of R-36-O and Tsyklon launch vehicles authorised Nation: USSR. Spacecraft: IS-A, US-A, OGCh. 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 Yangel’s R-36 rocket was superior to Chelomei’s 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.References: 474.
1967 July 1 - Launch Vehicle: Tsyklon 2. - Tsiklon-2 launch vehicle authorised. Nation: USSR. Spacecraft: US-A, IS-A, Meteor. Council of Soviet Ministers (SM) Decree 'On use of the R-36-based launcher for the Kosmos and Meteor satellites' was issued. References: 474.
1967 July 21 - Launch Vehicle: R-36-O, Tsyklon 2, Soyuz 11A511M. - US Project reassigned; R-36-O booster development approved; Yantar-2K and Zvevda 7K-VI approved. Nation: USSR. Spacecraft: US-A, US-P, Yantar-2K, Yantar-4K1, Soyuz VI. Decree 715-240 'On the Creation of Space Systems for Naval Reconnaissance Comprising the US sat and the R-36-based booster -further work on the US naval reconnaissance satellite, approval of work on the Yantar-2K, and course of work on 7K-VI Zvezda'.
An entire family of Yantar spacecraft was proposed by Kozlov’s design bureau during the initial development; information on two film return models has been declassified. Yantar was initially derived from the Soyuz spacecraft, including systems developed for the Soyuz VI military model. During design and development this changed until it had very little in common with Soyuz. Following numerous problems in the first flight tests of the Soyuz 7K-OK, Kozlov ordered a complete redesign of the 7K-VI manned military spacecraft. The new spacecraft, with a crew of two, would have a total mass of 6.6 tonnes and could operate for a month in orbit. The new design switched the positions of the Soyuz descent module and the orbital modules and was 300 kg too heavy for the standard 11A511 launch vehicle. Therefore Kozlov designed a new variant of the Soyuz launch vehicle, the 11A511M. The project was approved by the Central Committee of the Communist Party, with first flight to be in 1968 and operations to begin in 1969. The booster design, with unknown changes to the basic Soyuz, did not go into full production.References: 474.

However factory markings on the recovered material proved to the Air Force analysts that they were dealing with an ASAT weapon.References: 1, 2, 5, 6.
