The SS-NX-13 submarine-launched ballistic missile is a short-range, two-stage, storable liquid-propellant missile apparently designed for an anti-ship role. It is capable of delivering a reentry vehicle in the 2500-lb class, containing a warhead with a yield of 2.0 to 3.5 MT, to a minimum operational range of 80 nm or a maximum operational range of 360 nm. The missile flies a lofted trajectory, and is unique in that it has an impact-point correction capability of up to 30 nm through use of a restartable second-stage. The missile uses an inertial guidance system aided by an onboard passive ELINT target sensor. In a pure ballistic mode the SS-NX-13 is capable of a CEP of about 0.3 nm, and against cooperative targets, i.e., a target emanating radio-frequency transmissions, the SS-NX-13 is capable of a CEP of 0.1 to 0.2 nm.
