这 西科斯基HH-52海员 （公司名称S-62）是一架单涡轮发动机，三叶片转子两栖直升机。最初由康涅狄格州斯特拉特福德的西科斯基飞机公司开发，主要用于海空救援。HH-52已被非两栖类型所取代，如HH-65海豚，它完全依靠低悬停的绞车进行救援行动。

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.
