The Yu-2 is a Chinese copy of the Soviet RAT-52 air-launched, solid-fuel rocket-propelled, anti-ship torpedo. China obtained the torpedo in 1954, and all related technical documents in 1958. The licensed production was carried out by 123 Factory. The first torpedo rolled out in July 1960 but the test launch was failed. 347 Factory resumed the production in 1964 and the torpedo received its design certificate in 1971.

鱼-2型是苏联RAT-52型空射、固体燃料火箭推进反舰鱼雷的一种中国仿造型。中国在1954年获得了鱼雷，并在1958年获得了所有的相关技术文件。获得许可下由三机部123工厂进行生产。最初鱼雷在1960年7月生产，但是试射失败。347工厂在1964年重新开始生产，并且鱼雷在1971年接受到了它的设计证明书。

Carried by H-5 bomber or Q-5 attacker, the Yu-2 was designed to fly using rocket engine in air at high speed before it hits the water at a very close distance to the surface target. Only a small number was delivered to the Navy before the production was completely stopped. The torpedo is no longer in service.

由轰-5型轰炸机或强-5型强击机携带，鱼-2型设计采用火箭发动机在空中高速飞行，当在非常接近到水面目标的距离时进入水面。在被完全停止生产前只有少量的鱼-2型交付给海军。鱼雷目前不在服役中。
