HS-3

Helicopter Anti-Submarine Squadron THREE (HS-3), known as the "Tridents," was established on June 18, 1952. Operating primarily from Naval Air Station Jacksonville, Florida, HS-3 played a pivotal role in anti-submarine warfare (ASW) during the Cold War, employing a variety of aircraft including the SH-3 Sea King and later the SH-60F/HH-60H Seahawk helicopters. The squadron participated in numerous deployments aboard aircraft carriers, supporting NATO and U.S. Navy operations across the Atlantic and Mediterranean. In December 2009, HS-3 was redesignated as Helicopter Sea Combat Squadron NINE (HSC-9), transitioning to a broader mission set with the MH-60S Seahawk.
