In 1962, the U.S. Coast Guard selected a version of the civil Sikorsky S-62 amphibian helicopter to serve as its medium-range search and rescue helicopter.  The S-62 was the first amphibious helicopter built with a flying boat type hull, and was the first turbine powered helicopter in Coast Guard service.  The first HH-52A Seaguards entered service in 1963, with an eventual total of 99 in the Coast Guard.  In addition to their service from shore bases, the Seaguards also flew from Coast Guard icebreakers.  The Seaguard remained in service until 1989 and was credited with saving the lives of over 15,000 people.
