The H-5 was designed to provide a helicopter having greater useful load, endurance, speed, and service ceiling than the Sikorsky R-4. The first XR-5 of four ordered made its initial flight on August 18, 1943. In March 1944, the United States Army Air Forces ordered 26 YR-5As for service testing, and in February 1945, the first YR-5A was delivered.

In December 1946 an agreement was signed between Westland and Sikorsky to all and anglicized version of the S-51 to be manufactured under license in Britain as the Westland-Sikorsky WS-51 Dragonfly.
