Seaslug was a first-generation surface-to-air missile designed by Armstrong Whitworth for use by the Royal Navy. Tracing its history as far back as 1943's LOPGAP design, it came into operational service in 1961 and was still in use at the time of the Falklands War in 1982.

A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground or the sea to destroy aircraft or other missiles. It is one type of anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles.
