RSM-56 Bulava

The Bulava (Russian: Булава, lit. "mace"; designation RSM-56, NATO reporting name SS-NX-30 or SS-N-32 , GRAU index 3M30) is a submarine-launched ballistic missile (SLBM) developed for the Russian Navy and deployed in 2013 on the new Borei class of ballistic missile nuclear submarines. It is intended as the future cornerstone of Russia's nuclear triad, and is the most expensive weapons project in the country. The weapon takes its name from bulava, a Russian word for mace. Bulava has slightly greater range but a 30%+ lower throw-weight than the 1979 American Trident C4 missile.

Designed by Moscow Institute of Thermal Technology, development of the missile was launched in the late 1990s as a replacement for the R-39 Rif solid-fuel SLBM. It is expected that the first three Borei-class submarines will carry 16 missiles, while the following five vessels will carry 20 missiles. Development and deployment of the Bulava missile within the Russian Navy is not affected by the enforcement of the new START treaty.

The missile's flight test programme was problematic. Until 2009, there were 6 failures in 13 flight tests and one failure during ground test, blamed mostly on substandard components. After a failure in December 2009, further tests were put on hold and a probe was conducted to find out the reasons for the failures. Testing was resumed on 7 October 2010 with a launch from the Typhoon-class submarine Dmitri Donskoi in the White Sea; the warheads successfully hit their targets at the Kura Test Range in the Russian Far East. Seven launches have been conducted since the probe, all successful. On 28 June 2011, the missile was launched for the first time from its standard carrier, Borei-class submarine Yury Dolgorukiy, and on 27 August 2011 the first full-range (over 9,000 km (5,600 mi)) flight test was conducted. After this successful launch, the start of serial production of Bulava missiles in the same configuration was announced on 28 June 2011. A successful salvo launch on 23 December 2011 concluded the flight test programme. The missile was officially approved for service on 27 December 2011, and was reported to be commissioned aboard the Yuri Dolgorukiy on 10 January 2013. The missile did however continue to fail in the summer of 2013 and was not operational as of November 2013. The Bulava is finally operational aboard Yury Dolgorukiy as of October 2015. However, recent developments put this in question. In November 2015, the Vladimir Monomakh sub fired two missiles while submerged. One of the missiles self-destructed during the boost phase and the other failed to deliver its warheads to the specified target. After being sent back to the manufacturer, it was determined that the missiles failed due to manufacturing defects.
