Helicopter Anti-Submarine Squadron Light 31 (HSL-31), also known as the "Arch Angels," was a U.S. Navy helicopter squadron established in 1969. Based at Naval Air Station North Island, California, HSL-31 served primarily as a Fleet Replacement Squadron, training pilots and aircrew to operate the SH-2 Seasprite helicopter for anti-submarine warfare and other naval missions. Over its years of service, the unit played a critical role in preparing crews for deployment aboard surface combatants. HSL-31 was disestablished in 1994 as part of a broader reorganization of Navy helicopter units.

Navy Reserve Training Center (NRTC) Orlando served as a critical hub for training and supporting Navy Reserve personnel in Central Florida. Established to provide administrative, operational, and logistical support, NRTC Orlando enabled reservists to maintain readiness and integrate seamlessly with active-duty forces. Throughout its history, the center hosted drills, professional development, and mobilization preparations for sailors assigned to various reserve units. Its presence contributed significantly to the Navy’s mission by ensuring a well-prepared reserve force ready to respond to national and global requirements.

Helicopter Anti-Submarine Squadron TEN (HS-10), known as the "Warhawks," was established by the United States Navy in 1952. The squadron served as a Fleet Replacement Squadron tasked with training pilots and aircrew in anti-submarine warfare (ASW) helicopter operations. Over its history, HS-10 operated a range of helicopters, including the HSS-1 Seabat, SH-3 Sea King, and later the SH-60 Seahawk. The squadron played a crucial role in developing ASW tactics and supporting fleet readiness until its disestablishment in 2012.
