Per start preparation at Kasputin Yar
The Burya ("Storm" in Russian; Russian: Буря) was a trisonic, intercontinental cruise missile developed by the Lavochkin design bureau (designation La-350), based on a request for proposal issued by the Soviet government in 1954.[1] The purpose of the design competition was to develop a cruise missile capable of delivering a nuclear payload to the United States. Analogous developments in the USA were the SM-62 Snark and SM-64 Navaho cruise missiles, particularly the later, which used parallel technology and had similar performance goals.
Development[]
The Burya was planned as a Mach 3 intercontinental nuclear armed ramjet cruise missile. After cancellation, testing continued as a technology demonstration. The Burya was remarkably advanced for its time, and despite setbacks and several crashes, the vehicle demonstrated a range in excess of 6,000 km with a thermonuclear (hydrogen) bomb-sized payload at speeds greater than Mach 3. The Burya had a two stage design - the daring concept for an intercontinental missile was the second stage, which was powered by a ramjet engine at its operational speed of Mach 3. This varied from the original Trommsdorff concept of World War II in that no mother aircraft launch preceded the rocket boosted phase. The first stage was a ballistic-rocket-derived booster, which accelerated the Burya to altitude and the speed necessary to light up its ramjet engine: the ramjet was basically worthless at subsonic speeds, and would have become more complex as its operating speed range was broadened.
Successful tests were achieved only several years after the project was cancelled for operational purposes. It was a casualty, like the USAF Navaho, of the greater simplicity and relative invulnerability to interception of pure ballistic missiles. The missile was an early precursor to the Zvezda and Buran projects.[2]
