The former NAS Lakehurst also hosted the U.S. Navy's first helicopter squadrons, HU-1 (later HC-1) and HU-2 (later HC-2); the "A" and "C" enlisted training schools for the Aerographer's Mate (AG), Aviation Boatswain Mate (AB, ABE, ABF, ABH), and Parachute Rigger / Aircrew Survival Equipmentman (PR) ratings until their transfer to other Naval Air Technical Training Centers; and an Overhaul & Repair (O&R) facility for fixed-wing aircraft, the forerunner of the former Naval Air Rework Facilities and Naval Aviation Depots (NADEPs) now known as Fleet Readiness Centers (FRCs).
