The Yu-11 (Chinese: 鱼-7; pinyin: yú-7; lit. 'fish 7'; from Chinese: 鱼雷; lit. 'fish bomb', meaning ‘torpedo’) is a lightweight torpedo developed by the People's Republic of China.

Description

It entered service in the 2010s as the principal anti-submarine weapon of major People's Liberation Army Navy (PLAN) warships. It was first publicly identified in July 2015. Compared to its predecessor Yu-7 torpedo, the major improvement appears to be the pump-jet propulsor. The Yu-11 torpedo is quieter and may potentially operate at depths greater than 600 metres. The Yu-11 is longer, at three metres, and heavier than the Yu-7.

The Yu-11 is likely to become the standard PLAN lightweight torpedo and may have started equipping modern PLAN warships since 2012. The overall capability is said to be similar to the US Mark 50 torpedo.

The export version Yu-11E or ET-81 was unveiled in 2022. It can be launched from a C802 platform, or from export variants of 056A and 054A. The payload is based on the ET52C or ET60.
