The R-29RMU2 Liner is a Russian liquid-fuelled submarine-launched ballistic missile developed by the Makeyev Rocket Design Bureau and produced by the Krasnoyarsk Machine-Building Plant.[1] Although derived from the R-29RMU Sineva SLBM, the Liner can carry twelve nuclear warheads, twice that of the Sineva's. Reportedly capable of piercing anti-ballistic missile defences, the Liner, with its high payload-mass ratio, was described by its developer as the best ballistic missile in existent. It is expected to enter service with the Russian Navy's Delta IV class submarines shortly after a successful test programme that spanned from May to September 2011.

History and design

On 9 August 2011, the Russian Ministry of Defense disclosed the details of the Liner SLBM, the first launch of which occurred on 20 May earlier that year.[1][2] The authorities originally claimed the launch to be of a Sineva missile, but on 23 May revealed the missile fired was actually the Liner.[3][4] The successful firing, aimed at the Kura Test Range, was conducted from the submarine Ekaterinburg.[1][5]

The second launch of the Liner missile took place on 29 September 2011, from the submarine Tula in the Barents Sea aimed at the Kura Test Range.[6][7] Following the second, successful Liner test, the Russian Navy decided to accept the missile into active service to augment the RSM-56 Bulava missile and improve the future viability of the Delta IV class submarines until at least 2030.[8][9]

The Liner missile is a highly-advanced derivative of the three-stage liquid-propelled R-29RMU Sineva SLBM, which was accepted into service in 2007.[1][10] While many technical details have not yet been disclosed, it is known that the missile is capable of carrying up to twelve low-yield nuclear warheads called MIRVs capable of striking several targets individually.[10] This is twice the number of warheads the Sineva can carry, and, unlike those of the Sineva, these warheads can be of various yields with less warheads.[9] While it shares flight characteristics with the Sineva, the Liner is equipped with improved systems to overcome anti-ballitic missile shields.[11] Due to its high payload-mass ratio, the missile reportedly outclasses all solid-fueled strategic missiles in the Western Hemisphere and China.[10]
