The SPARS were assigned to every USCG district except Puerto Rico, and served in Hawaii and Alaska as well. Most officers were general duty officers, although some served as communication, supply and recruiting officers. Most of the enlisted women performed clerical duties, but they also rigged parachutes and drove jeeps. A select few officers and enlisted personnel were assigned to work with the Long Range Aid to Navigation at monitoring stations in the Continental United States. Better known as LORAN, it was a top-secret radio navigation system developed for ships at sea and long-range aircraft. The SPARS peak strength was approximately 11,000 officers and enlisted personnel. Commodore J. A. Hirschfield, USCG said that the SPARS volunteered for duty when their country needed them, and they did their jobs with enthusiasm, efficiency, and with a minimum of fanfare. Two United States Coast Guard Cutters were named in honor of the SPARS.
