The gallery above reproduces the “Lockheed Constitution Development Story,” a publication from December 1950 summarizing the design and development of the Lockheed XR6O-1 Constitution, a huge aircraft initiated in 1942 by Lockheed as a long-range, high capacity transport and airliner for Pan American Airways and the U.S. Navy. Only two Constitutions were ultimately built, both serving with the Navy, where it proved to be underpowered and too large for practical airline use at the time.

The brochure presented here appears to have been part of an unsuccessful marketing effort by Lockheed for a turbine-powered commercial version of the aircraft. It contains many detailed photographs and drawings of the Constitution as built, as well as deck plans of the unrealized commercial version. To view the document in high resolution, please click through the gallery above.
