The R-36O 8K69 was manufactured by Yuzhnoye Design Bureau with the first launch on 1965-07-28. R-36O 8K69 has 19 successful launches and 2 failed launches with a total of 21 launches. The R-36O was the only orbiting military nuclear weapon ever deployed, although in order to remain legal under international treaties it was a ‘fractional orbital’ weapon. Although American infrared early warning satellites invalidated the ‘surprise attack’ component of the concept, 18 missiles were operational from 1969 to 1983.
