The Shorts Blowpipe is a man-portable (MANPADS) surface-to-air missile that was in use with the British Army and Royal Marines from 1975. It also saw service in other military forces around the world. Most examples were retired by the mid-1990s. It is unique among MANPADS in that it is manually guided to its target with a small joystick, sending guidance corrections to the missile over a radio control link. Several advanced variants and alternative launchers, including a submarine-based system, did not see production. Approximately 35,000 missiles were produced in total.
