The single Douglas XC-116 was a sister to the XC-114, and like that aircraft was a version of the C-54 with a longer (100ft 7in compared to 93ft 10in) fuselage. The only difference was the use of thermal de-icing equipment on the XC-116 in place of the pneumatic boots used on the XC-114 and C-54s. Neither the XC-114 nor XC-116 entered production, while the Packard V-1650 powered XC-115 never even reached the prototype stage. The end of the Second World War, and the existence of large numbers of C-47s, C-53s and C-54s allowed the USAAF to wait for the development of more powerful transport aircraft.
