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

Description

[edit]

It entered service in the 2010s as the principal anti-submarine weapon of major People's Liberation Army Navy (PLAN) warships.[1] 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.[1]

The Yu-11 is likely to become the standard PLAN lightweight torpedo and may have started equipping modern PLAN warships since 2012.[1] The overall capability is said to be similar to the US Mark 50 torpedo.[2]

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.[3]
