Two S-62 prototypes were completed, with 1,050 shp T58-GE-6 engines derated to 670 shp. The design utilized the main and tail rotor of the S-55. The maiden flight occurred on May 22, 1958 by c/n 62-001, N880. Subsequently, world-wide demonstration flights were made and the FAA type certificate was awarded on June 30, 1960. The prototypes were followed by the S-62A for civil passenger and utility use. One S-62B was built utilizing the four bladed main rotor of the S-58, however, shortened by .33m. The improved S-62C was built and ordered by the US Navy for the US Coast Guard, initially as the HU2S-1G, then redesignated in 1962 as the HH-52A Seaguard. Mitsubishi built the type under license as the S-62J for Japanese domestic use.
