Type 081 / 081A Wochi-class mine countermeasure vessel

The Type 081 / 081A Wochi class is a Chinese People's Liberation Army Navy mine countermeasure vessel family that covers the original Type 081 batch and the enlarged Type 081A follow-on ships. Open sources describe the class as a PLAN minesweeper and minehunter family built by Qiuxin Shipyard in Shanghai and later expanded with the Type 081A variant, which carries a 30 mm gun and larger displacement than the earlier 37 mm-armed batch.
