Wuhan-class Trials Submarine

The single unit Wuhan-class Trials Submarine is a Modified R-class submarine with YJ-1 (CSS-N-4) anti ship missiles launchers. The six YJ-1 missiles have active radar homing to 40 km (22nm) at 0.9 mach sea-skimming and has a 165kg war head. It's also armed with 533mm torpedoes with passive homing to 15 km at 40 knots and has warhead of 400 kg. The sub can also carry 20 mines in lieu of torpedoes. This sub is built as a trials SSM platform, and others may be converted in due course. The six missile tubes are built into the casing abreast the fin and elevate to fire much as in the Soviet Juliett class. To provide target acquistion an additional radar mast (snoop tray) is mounted between two periscopes.
