Consolidated 39 Liberator Liner



The Model 39 Liberator Liner was derived from the B-24 Liberator bomber via the PB4Y-2 Privateer patrol bomber and RY-3 Liberator Express transport. It retained the basic wing, landing gear, empennage, and engine nacelles of the Privateer; however, the fuselage was completely redesigned to carry 48 passengers in a day-time configuration or 24 at night. Like the Privateer, the Liberator Liner had four 1,350hp (1,000kW) Pratt & Whitney R-1830-94 Twin Wasp engines. The normal cruising speed was 240mph (385km/h), and the maximum range was 4,000ml (6,400km). Two were built and the first was used briefly for experimental all-cargo service in American Airlines markings, but the Liberator Liner never really had a chance because of the many Douglas C-54s that were about to be released for civilian use. Both were scrapped late in 1945 after it became obvious that the design had no potential.
