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. The project was canceled before flight tests began. It is unrelated to the later Buran reusable orbiter.
