37mm Type 76

History

The Type 76 37mm twin naval gun (Chinese: 76式双37舰炮) was developed by CSIC No.713 Institute in 1970s, project name "Type 715". In 1976, it adopted as Type 76 (later renamed as H/PJ-76 due to naming system change). The gun mounting is often confused with 37mm Type 61 (Chinese copy of Soviet V-11M), many sources do believe it's an improved variant of Type 61, but they are actually different systems, the development work of Type 76 started even earlier than that of Type 61. The gun mounting is capable to aim automatically under the direction of fire control, but still need in-turret crews to fire the guns. Manual operating is also available. The gun is belt feed, firing special "37mm Naval" round which is different to Soviet 37×252mm.SR round used on Type 61 and V-11M, a drum magazine contains 1600 rounds is placed belowdecks. Rate of fire is 800 rpm, effective range is about 4.5km.

Fire control system of Type 76 is H/LJP-341 radar. As for Type 76A, newer H/LJP-347 radar and JPT4 optics control station are also available.
