Teh Σικόρσκι HH-52 Ναυαγοσώστης (ονομασία εταιρείας S-62) ήταν ένας κινητήρας μονής τουρμπίνας, αμφίβιο ελικόπτερο τριών πτερυγίων. Αρχικά αναπτύχθηκε ως εμπορική επιχείρηση από την Sikorsky Aircraft Corporation του Στράτφορντ του Κονέκτικατ, χρησιμοποιήθηκε από την Ακτοφυλακή των Ηνωμένων Πολιτειών κυρίως για διάσωση από αέρος-θαλάσσης. Το HH-52 έχει αντικατασταθεί από μη αμφίβιους τύπους όπως το HH-65 Dolphin, οι οποίοι βασίζονται αποκλειστικά στη χρήση βαρούλκου από χαμηλή αιώρηση για τη διεξαγωγή επιχειρήσεων διάσωσης.

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.
