The R-29RM Shtil^[2] (Russian: Штиль, lit. "Calmness", NATO reporting name SS-N-23 Skiff) is a liquid propellant, submarine-launched ballistic missile in use by the Russian Navy. It has the alternate Russian designations RSM-54 and GRAU index 3M27.^[3] It is designed to be launched from the Delta IV submarine, each of which is capable of carrying 16 missiles.

Operation Behemoth

On 6 August 1991 at 21:09 Novomoskovsk, under the command of Captain Second Rank Sergey Yegorov, became the world's only submarine to successfully launch an all-missile salvo, launching 16 R-29RM (RSM-54) ballistic missiles of total weight of almost 700 tons in 244 seconds (operation code name "Behemoth-2"). The first and the last missiles hit their targets; the remaining missiles were intentionally caused to self-destruct in flight.

Previously, the largest number of missiles launched from a submerged SSBN was four Trident II missiles.

Performance

The R-29RM carries four 100 kiloton warheads and has a range of about 8,500 kilometres (5,300 mi).^[4]

End of service

The last boat carrying R-29RM, K-51 Verkhoturye, went into refit to be rearmed with the newer R-29RMU Sineva on 23 August 2010. ^[5]

Space Launch Vehicle

Several R-29RM were retrofitted as Shtill carrier rockets to be launched by Delta-class submarines, the submarines being mobile can send a payload directly into a heliosynchronic orbit, notably used by imaging satellites. Outside the confines of the Russian military, this capability has been used commercially to place three out of four microsatellites into a low earth orbit with one cancellation assigned to the Baikonur Cosmodrome for better financial terms.
