HSL-46

Helicopter Anti-Submarine Squadron Light 46 (HSL-46), known as the "Grandmasters," was established on April 7, 1988, at Naval Air Station Mayport, Florida. The squadron’s primary mission was to provide anti-submarine warfare (ASW), anti-surface warfare (ASUW), and search and rescue (SAR) capabilities using the SH-60B Seahawk helicopter. HSL-46 deployed detachments aboard various U.S. Navy surface combatants, supporting fleet operations and exercises worldwide, particularly in the Atlantic and Mediterranean regions. In 2012, as part of the Navy's helicopter reorganization, HSL-46 was redesignated as Helicopter Maritime Strike Squadron 72 (HSM-72), transitioning to the MH-60R Seahawk and continuing its legacy of excellence.
