Lla Garde-mer Sikorsky HH-52 (désignation de la société S-62) était un hélicoptère amphibie à rotor à turbine unique et à trois pales. Développé à l’origine comme une entreprise commerciale par la Sikorsky Aircraft Corporation de Stratford, Connecticut, il a été utilisé par la Garde côtière des États-Unis principalement pour le sauvetage air-mer. Le HH-52 a été remplacé par des types non amphibies tels que le HH-65 Dolphin, qui reposent uniquement sur l’utilisation d’un treuil à partir d’un vol stationnaire bas pour mener des opérations de sauvetage.

General Characteristics and Role
The Sikorsky HH-52 Seaguard was a crucial amphibious helicopter used primarily by the United States Coast Guard (USCG) for shipboard and shore-based search and rescue (SAR) operations, as well as law enforcement missions. It was based on the S-62 commercial helicopter and was the world’s first amphibious helicopter in large-scale production, a key feature that defined its service. The HH-52’s ability to land directly on water, thanks to its boat-like hull and outrigger pontoons, gave the USCG a major advantage in maritime rescue operations. Its service spanned over 26 years, making it one of the most reliable and successful assets in the Coast Guard’s history, credited with saving thousands of lives.
