Sea Dart

Sea Dart, also known as GWS.30, followed earlier British naval missile work and became the Royal Navy's principal area air-defense missile of the late Cold War. It was associated most strongly with Type 42 destroyers but also equipped larger ships. The system reflected the Royal Navy's need to defend task groups from Soviet bombers, maritime strike aircraft, and high-altitude threats.

Technically, Sea Dart was a ship-integrated weapon system rather than only a missile round. It used a launcher, magazine, fire-control radar, and command systems to engage aircraft and some missile targets. The weapon offered greater range than point-defense systems such as Sea Cat or Sea Wolf, but it required shipboard sensor support and had performance limits against very low-level or cluttered targets.

Operationally, Sea Dart shaped Royal Navy air-defense doctrine for decades. It saw combat in the Falklands War, where Type 42 destroyers used it for task-force air defense under difficult low-level attack conditions, and it later remained relevant in Gulf operations. Its eventual retirement with Type 42 destroyers marked the transition to Type 45 destroyers and the Sea Viper/Aster generation.
