The Yu-1 is China’s first indigenously made torpedo. A Chinese copy of the Soviet 53-51 non-homing torpedo, the Yu-1 is designed to be launched from Type 033 (Romeo class) submarine and Type 25 (Huchuan class) torpedo fast attack craft (FAC). The torpedo is obsolete and has been replaced by the more capable indigenous and imported designs. The improved Yu-1A uses passive acoustic-homing and is still in service.

鱼-1（Yu-1）型是中国第一种自行研制鱼雷。苏联53-51非-导引鱼雷的中国仿制型，鱼-1设计用于从033型（罗密欧级）潜艇和25型（湖川（Huchuan）级）鱼雷快艇（FAC）发射。鱼雷已过时并且已经被更有能力的中国自行研制和引进设计的新型鱼雷代替。改进的鱼-1A型采用被动声导并且仍然在服役中。

PROGRAM

Under the 1950 Treaty of Friendship, Alliance, and Mutual Assistance between China and Soviet Union, Moscow agreed to help the newly established People’s Republic of China (PRC) to build a modern military and defence industry. As part of the agreement, the Soviet Union transferred its torpedo technologies and some samples to China for reverse-engineering and licensed production. The indigenous torpedo development was carried out by Xi’an-based 507 Institute (now Xi’an Precision Machinery Institute).

计划

在1950年《中苏友好同盟互助条约》之下，莫斯科同意帮助新成立的中华人民共和国（PRC）建立一个现代化的军队和国防工业。当做协议的部分，苏联转移它的鱼雷技术和一些样品到中国用于反向工程和许可生产。中国本国自行研制鱼雷发展由西安507所（现在西安精密机械研究所）进行。

Assessment between different Soviet torpedo designs led to the decision to develop a kerosene-air wet heater propulsion, non-homing torpedo on the basis of the Soviet 53-51 torpedo. Experienced technicians and engineers were recruited from across the country to join the torpedo development team. The first torpedo was finished in March 1966, but various design flaws were identified in the following test launch. A joint development team with engineers from the PLA Navy, a number of factories and research institutes was formed to solve these problems. After extensive tests which lasted for 18 months, the development was successful in 1971. The torpedo received its design certificate in March 1971 and entered operational service shortly after.

在不同的苏联鱼雷设计之间评估后决定以苏联53-51型鱼雷为基础，去发展一种瓦斯湿式热动力、非-自导引鱼雷。富有经验的技术人员和工程师从跨跃整个中国招集参加鱼雷发展队伍。第一枚鱼雷在1966年3月完成，但是在接着的试射中发现各种不同的设计瑕疵。一个联合开发组，由来自PLA海军、许多的工厂和研究所的工程师组成，去解决这些问题。在持续18个月的广泛测试之后，发展在1971年获得成功。鱼雷在1971年3月接受了它的设计证明书并在之后不久进入了操作服役。

DESIGN

The Yu-1 is a heavyweight, non-homing, wet heater propulsion torpedo designed to engage surface ships. The torpedo is powered by a kerosene-air wet heater propulsion, giving a maximum speed of 50kt. The torpedo has a range of 9km and is armed with a 400kg warhead. An improved variant Yu-1A is fitted with passive acoustic-homing.

设计

鱼-1型是一种重型、非-自导引、湿式热动力鱼雷，设计去同水面舰艇交战。鱼雷采用瓦斯湿式热动力，最大速度50节。鱼雷射程9公里，配备一个400公斤弹头。改进型鱼-1A配备有被动声导头。
