RIM-7 Sea Sparrow is a ship-borne short-range anti-aircraft and anti-missile weapon system, primarily intended for defense against anti-ship missiles. The system was developed in the early 1960s from the AIM-7 Sparrow air-to-air missile as a lightweight "point defense" weapon that could be retrofitted to existing ships as quickly as possible, often in place of existing gun-based anti-aircraft weapons. In this incarnation it was a very simple system, guided by a manually aimed radar illuminator. Since its introduction, the Sea Sparrow has undergone significant development and now resembles the AIM-7 only in general form; it is larger, faster and includes a new seeker and launch system suitable for vertical launch from modern warships. The Sea Sparrow remains an important part of a layered air defense system, providing a short/medium-range component especially useful against sea-skimming missiles.
