Date of Introduction
1991
Description
The Type 037IG missile boat (NATO: Houxin class) were first built by Qiuxing and Huangpu Shipyard from 1991 through 1999 for the People's Liberation Army Navy (PLAN). In addition to the PLAN, 6 were exported to Myanmar: 2 in 1995, 2 in July 1996, and 2 in late 1997. This boat is the anti-ship version of the Type 037 submarine chasers, armed with missiles rather than torpedoes. It is most effectively used in conjunction with multiple missile boats to send a swarm of missiles towards its intended target and then egress from the area immediately. The swarm of anti-ship missiles will hopefully slip past the target's air defenses for at least one or possibly more hits.

Note
The Type 76A is a fully enclosed and fully automatic model in the Type 76 series. Unlike the Type 76F, the gun is fully automatic, with the semi-automatic operational mode and the one-man operator console removed. In addition to the optronic FCS found in the Type 76F, the Type 76A is linked to radar FCS. The maximum rate of fire, however, is reduced in comparison to Type 76, dropping from the original 400 rd/min/barrel to 375 rd/min/barrel. In addition to anti-aircraft and anti-surface roles, the Type 76A can also be used as a close-in-weapon system.
