Tá Sikorsky HH-52 Seaguard (označení společnosti S-62) byl jednomotorový turbínový motor, třílistý rotorový obojživelný vrtulník. Původně byl vyvinut jako komerční podnik společností Sikorsky Aircraft Corporation ve Stratfordu v Connecticutu a byl používán pobřežní stráží Spojených států především pro záchranu vzdušného moře. HH-52 byl nahrazen neobojživelnými typy, jako je HH-65 Dolphin, které se při provádění záchranných operací spoléhají výhradně na použití navijáku z nízkého vznášedla.

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.
