Type 037-IG Houxin Class Missile Corvette
Last updated: 12 October 2007
The Type 037-IG (NATO reporting name: Houxin class) is a missile corvette developed from the hull of the Type 037I (Haijiu class) anti-submarine patrol craft. The vessel was developed as an low-cost alternative to the more capable Type 037-II (Houjian class) missile corvette introduced roughly the same time. A total of 24 hulls were built by Shanghai-based Qiuxin Shipyard between 1991 and 1997, with six of them sold to the Myanmar Navy in the mid-1990s.
Inventory
24 hulls, all in the South Sea Fleet: 651~656, 751~769
Weapons
The Type 037IG is generally similar to the Type 037I in hull design, but has the VDS equipment and depth charge projectors and racks on the stern deck removed to give room for two three-cell YJ-8 anti-ship missile launchers. The missile uses active radar homing and is powered by a solid rocket engine with a solid rocket booster. The missile has a range of 40km and approaches the target in sea skimming mode at a speed of Mach 0.9. The 165kg shaped charge warhead has time delayed impact proximity fuses.
