ザ シコルスキー HH-52 シーガード (会社指定S-62)は、単一のタービンエンジン、3ブレードローター水陸両用ヘリコプターでした。もともとストラトフォード、コネチカット州のシコルスキー航空機公社によって商業ベンチャーとして開発され、それは主に空海救助のために米国沿岸警備隊によって使用されました。HH-52は、救助活動を行うために低ホバーからのウィンチの使用だけに依存するHH-65ドルフィンのような非水陸両用タイプに置き換えられました。

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.
