Development

Entwicklung

IThe Sikorsky HNS-1 (R-4) was a two-place helicopter designed by Igor Sikorsky with a single, three-bladed main rotor and powered by a radial engine. The HNS-1 was the world's first mass-produced helicopter and the first helicopter to enter service with the Navy, and Coast Guard.

The first flight of the new helicopter was made in January 1942, and 130 production examples were soon produced. The R-4 recorded two firsts: it accomplished the first helicopter landing aboard a ship, and the first rescue by a helicopter. Twenty-five HNS-1 were operated by the U.S. Navy and U.S. Coast Guard.
