Nas Jax hs1

Helicopter Antisubmarine Squadron One (HS-1), known as the "Seahorses," was established at Naval Air Station Jacksonville (NAS Jax), Florida, in 1951. As the U.S. Navy’s first helicopter antisubmarine warfare (ASW) squadron, HS-1 pioneered tactics and training for rotary-wing ASW operations during the Cold War. Throughout its history, HS-1 played a key role in developing helicopter doctrine, serving as the Fleet Replacement Squadron (FRS) to train generations of pilots and aircrew. The squadron was decommissioned in 1997, leaving a lasting legacy in naval aviation and antisubmarine warfare.
