The Yu-7 (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. It entered service in the 1990s as the principal anti-submarine weapon of major People's Liberation Army Navy (PLAN) warships. The Yu-7 is a derivative of the Whitehead Alenia Sistemi Subacquei (WASS) A244/S torpedo.
Development of an effective lightweight anti-submarine (ASW) torpedo for the PLAN began in the 1980s. The program was probably based on 40 A244/S torpedoes purchased for evaluation from Italy in 1987. Additional technology may have been reverse engineered from a United States Mark 46 Mod 2 torpedo recovered from the South China Sea in 1978 by Chinese fishermen. The torpedo was initially equipped with electric propulsion, but inadequate performance led to a redesign powered by Otto fuel II. Testing was carried out at the 750 Testing Range in Kunming up to 1988.
The Yu-7 has contrarotating propellers. Aboard surface warships, it is fired from Type 7424 tripled 324 mm torpedo launchers; these are copies or derivatives of the WASS B515/ILAS-3.
The Yu-7 entered service in the 1990s.
The Yu-11 (Chinese: 鱼-11; pinyin: yú-11; lit. 'fish 11') is the successor to the Yu-7. It was first publicly identified in July 2015. 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.
