It was delivered on January 10, 1945 and immediately transferred to the USN as an R5D-2 and was subsequently used by the USMC. With the introduction of a new designation system in 1962, the aircraft was redesignated C-54P. It was placed in storage at the MASDC in February 1972 and was scrapped on December 26, 1974."
