in
US Coast Guard

The US Coast Guard evaluated the Sikorsky S-62A prototype N880 during 1959-1960. It was sufficiently impressed with the S-62s performance over the HO4S-3G/HH-19G that it ordered 99 to fulfill its short range SAR requirement. Intitially designated HU2S-1G Seaguard, it was re-designated as the HH-52A Seaguard in October 1962. Deliveries commenced in 1963 and were completed in 1967 along side its larger stablemate, the Sikorsky S-61R/HH-3F Pelican long-range SAR helicopter.

The HH-52 saved over 15,000 lives in its twenty-five years of service with the United States Coast Guard.
