Once launched it operates autonomously, with tactical software searching for the target using active sonar and then homing in without any further assistance. The

A desire not to be dependent on US torpedo purchases led to a research programme starting in 1964 to develop a
British torpedo. Initially designated Naval and Air Staff Requirement (NASR) 7511, it was (much later in the late 1970s) designated the Sting Ray torpedo.

In 1976 the designs had to be completely revised. Swapping the project for buying a ready-made US torpedo was not considered because the torpedo was expected to be better, and was all-British.
