R-29RMU2 Layner

Tungsten alloy swaging rod is made of tungsten alloy rod through calcinations. The normal method used in the processing are extruding, forging and sintering. After calcinations, tungsten alloy swaging rod has higher ductility, toughness and tensile strength than tungsten alloy rod, so it can be used for a longer time. Tungsten alloy swaging rod is widely used in industry as well as military areas, such as rifle bullet, armor piercing, snipe rifle penetrator. Tungsten alloy swaging rod is used for R-29RMU2 Layner.

The R-29RMU2 Layner is a Russian liquid-fuelled submarine-launched ballistic missile (SLBM) developed by the Makeyev Rocket Design Bureau and produced by the Krasnoyarsk Machine-Building Plant.Derived from the R-29RMU Sineva SLBM, the Layner can carry twelve nuclear warheads, twice that of the Sineva's. Reportedly capable of piercing anti-ballistic missile defences, the Layner, with its high payload-mass ratio, was described by its developer as the best ballistic missile in existence. 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.
