disclosed the details of the Layner SLBM, whose first launch occurred on 20 May earlier that year. The authorities originally claimed the launch to be of a Sineva missile, but on 23 May 2011 it was revealed that the missile fired was actually the Layner. The successful firing, aimed at the Kura Test Range

The second launch of the Layner missile took place on 29 September 2011 from the submarine K-114 ''Tula'' in the Barents Sea

Missile was recommended by the State Commission for adoption as of December 2012. Missile weapons complex D-29RMU2.1 with missile R-29RMU2.1 accepted for service by decree of the President of the Russian Federation in January 2014.
The Layner missile is a highly advanced derivative of the three-stage liquid-propelled R-29RMU2 Sineva SLBM, which was accepted into service in 2007.[ While many technical details are not disclosed, it is known that the missile is capable of carrying up to twelve low- yield ]nuclear warhead

s capable of striking several targets individually. This is twice the number of warheads the solid-propellant RSM-56 Bulava SLBM can carry, and, unlike those of the Sineva SLBM, these warheads can be of a mixed set with various yields.[ While it shares flight characteristics with the Sineva, the Layner is equipped with improved systems to overcome anti-ballistic missile shields.] The missile can carry twelve low-yield warheads without penetration aid
A penetration aid (or "penaid") is a device or tactic used to increase an intercontinental ballistic missile (ICBM) warhead's chances of penetrating a target's defenses.
These can consist of both ''physical devices'' carried within the ICBM (as p ...
