Open in interactive gallery →

The R-29RMU2.1 Lajner is a Russian liquid-fuelled submarine-launched ballistic missile (SLBM) and the newest member of the R-29 missile family, developed by the Makeyev Rocket Design Bureau and produced by the Krasnoyarsk Machine-Building Plant. Derived from the R-29RMU2 Sineva SLBM, the Lajner can carry twelve nuclear warheads, three times as many as Sineva. It was expected to enter service with the Russian Navy's Delta IV-class submarines after a successful test programme that spanned from May to September 2011. The Russian Navy confirmed in 2014 that the system was now in use.
