Den Sikorsky HH-52 Sjøvakt (selskapsbetegnelse S-62) var et enkelt turbinmotor, trebladet rotor amfibisk helikopter. Opprinnelig utviklet som et kommersielt venture av Sikorsky Aircraft Corporation i Stratford, Connecticut, ble det brukt av United States Coast Guard primært for luft-sjøredning. HH-52 har blitt erstattet av ikke-amfibiske typer som HH-65 Dolphin, som utelukkende er avhengige av bruk av vinsj fra et lavt svev for å utføre redningsoperasjoner.

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.
