Consolidated C-87 Liberator Express

The Consolidated C-87 Liberator Express was a transport derivative of the B-24 Liberator heavy bomber built during World War II for the United States Army Air Forces. A total of 287 C-87s were officially delivered from Consolidated Aircraft plant in Fort Worth, Texas. The plant also developed and delivered a USAAF flight engineer trainer designated as the AT-22. The AAF C-87A was an executive transport version of the C-87. The United States Navy VIP transport designated as the RY. The last development was a Navy contracted, single tail version with an extended fuselage. Built in San Diego, its USN designation was RY-3 and the AAF had order the design as the C-87C. Those were cancelled and allotted to a Royal Air Force VIP transport designated as the Liberator C.IX

In contrast, the C-109 Liberator was a fuel-transport converted from existing B-24 Bombers.
