HSL NAS Coronado

Helicopter Anti-Submarine Squadron Light (HSL) at NAS Coronado was a key component of the U.S. Navy’s rotary-wing anti-submarine warfare capabilities. Established during the Cold War, HSL squadrons operated SH-2 Seasprite and later SH-60B Seahawk helicopters, providing surface fleet support from the strategically vital Naval Air Station North Island in Coronado, California. These squadrons played a crucial role in maritime patrol, anti-surface warfare, search and rescue, and logistical support missions. Their operations contributed significantly to the Navy’s readiness and power projection in the Pacific and beyond until HSL units were reorganized into Helicopter Maritime Strike (HSM) squadrons in the mid-2000s.
