Despite the short period of the development, flight trials proved the airframe's flight characteristics satisfactory and the aircraft was rated very highly. In May 1945 a letter of intent for 598 production was signed. The name "Skyraider" was officially approved for the aircraft in February of the following year, and the distribution to units was started at the end of the same year.
