This was officially accepted in May, 1942 and although not the first helicopter to see military service, the XR-4 was the first mass-produced helicopter and the first successful production rotorcraft of single-rotor configuration. The XR-4C came to the Smithsonian Institution in 1947 as part of a larger gift of aircraft transferred from the USAF to the new National Air Museum. It is now on display at the Udvar-Hazy Center.
