Sikorsky XHJS
Introduction The '''Sikorsky XHJS-1''' (manufacturer designation '''S-53'''),  was developed by Sikorsky Aircraft to meet a Naval requirement for a utility helicopter. The XHJS-1 was not ordered into production and only two prototypes were built.
Design and development Powered by a  Continental R-975-34, the S-53 was a development of the S-51 designed for use on aircraft carriers. The tail rotor was raised above head-height to give more clearance and the landing gear was made stronger to enable operations from a moving deck. Other enhancements were a folding main rotor and the option for amphibious landing gear. Two prototypes were ordered by the United States Navy as the '''XHJS-1''' and the first flew on 22 September 1947.The type was evaluated against the Piasecki XHJP-1.With the Piasecki design being ordered as the HUP-1 by the Navy, the S-53 was not developed further.
