The R-29RMU2 Sineva (Russian: Синева, lit. "blueness"), code RSM-54, is a Russian liquid-fueled submarine-launched ballistic missile with GRAU index 3M27, designation SS-N-23A Skiff.^{[citation needed]} It can carry four warheads and is designed to be launched from Delta IV-class submarines, which are armed with 16 missiles each. As of 2017, there are 96 launchers deployed on the submarines.^[6]

The first full-range test was reportedly conducted on October 11, 2008; the reported range was 11,547 kilometres (7,175 mi). The R-29RMU2 entered service in 2007 and is expected to remain in service until at least 2030.^{[citation needed]}

Current plans call for the construction of approximately 100 such missiles.^[7]

The Sineva missile has reportedly been modified into R-29RMU2 Layner missile as of 2012.^[8]
