Overview
Overview

Development
Development
Development of the R-29RM started in 1979 at the Makeyev Rocket Design Bureau. The navy accepted the armament in 1986 and subsequently installed the D-9RM launch system consisting of a cluster of 16 R-29RM on board the nuclear-propelled Project 667BDRM submarines.
Operation Behemoth
Operation Behemoth
On 6 August 1991 at 21:09, K-407, 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 the total weight of almost 700 tons in 244 seconds (operation code name "Behemoth-2"). All the missile hit their designated targets at the Kura Missile Test Range in Kamchatka.
Space launch vehicle
Space launch vehicle
Several R-29RM were retrofitted as Shtil' carrier rockets to be launched by Delta-class submarines, the submarines being mobile can send a payload directly into a heliosynchronous 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.

End of service
The last boat carrying R-29RM, K-51, went into refit to be rearmed with the newer R-29RMU Sineva on 23 August 2010.
