RSS-40 Buran

The Buran (Russian: Буран, named for the Buran wind) cruise missile, designation M-40 (М-40) sometimes referred to as RSS-40, was a Soviet intercontinental cruise missile by Myasishchev capable of carrying a 3,500 kg hydrogen bomb payload.^[1] The project was canceled before flight tests began.^[2] It is unrelated to the later Buran reusable orbiter.

The project was authorized on 20 May 1954, parallel to the development of the Burya missile. The development however, began in April 1953 as a rocket-aircraft system by Myasishchev OKB with internal designation M-40.^[3] The project was canceled in November 1957, when two prototypes were just ready for flight testing, in favor of the R-7 Semyorka, since ICBMs were considered unstoppable. Like the Burya, the Buran consisted of two stages, the booster rockets designated M-41, and the cruise missile stage designated M-42.^{[citation needed]}
