With the onset of World War II, the TWA aircraft entering production were converted to an order for C-69 Constellation military transport aircraft, with 202 aircraft intended for the United States Army Air Forces (USAAF). The first prototype (civil registration NX25600) flew on 9 January, 1943, a simple ferry hop from Burbank to Muroc Field for testing.[1] Eddie Allen, on loan from Boeing, flew left seat, with Lockheed's own Milo Burcham as copilot. Rudy Thoren and Kelly Johnson were also on board.

Lockheed also proposed its model L-249 which was to be a long range bomber. It received the military designation XB-30 but the aircraft was never developed or built. A plan for a very long-range troop transport, the C-69B, was cancelled. A single C-69C, a 43-seat VIP transport, was built in 1945 at the Lockheed-Burbank plant.

The C-69 was largely used as a high-speed, long-distance troop transport during the war.[7] Only 22 C-69s were completed before the end of hostilities, and not all of those entered military service. The USAAF cancelled the remainder of the order in 1945.
