Sikorsky Aircraft Corporation designed the XR-5 in 1942 for the U. S. Army Air Forces. This two-seat helicopter could lift more than three times the maximum payload capacity of the Sikorsky R-4 helicopter. The Royal Navy enthusiastically endorsed the design as an anti-submarine patrol aircraft that could accompany and protect convoys crossing the Atlantic. However, manufacturing delays prevented any production R-5 aircraft from entering service before the end of World War II.
