About this Unit
Helicopter Anti-Submarine Squadron (Light) 84 (HSL-84) was a United States Navy helicopter squadron established as part of the Navy's growing need for anti-submarine warfare (ASW) capabilities during the Cold War era. Commissioned in 1978 and based at Naval Air Station North Island, California, HSL-84 operated the SH-2 Seasprite helicopter, providing ASW, search and rescue, and utility support primarily to surface combatants. The squadron's missions included protecting carrier battle groups and convoys against submarine threats, as well as supporting surface warfare operations. HSL-84 was ultimately disestablished in 1988 as part of a force restructuring and modernization of naval helicopter assets.
