The Lockheed XR6O-1 Constitution Naval Transport (four 3,500 h.p. Pratt & Whitney R-4-360 engines).
In spite of its bulk, the Constitution presented quite an elegant outline when flying “clean”.

On February 2, 1949, following its formal introduction into the US Navy by Rear Admiral Lynde McCormick, one of the XR6Os made a jet-assisted take off from Alameda, California, and buzzed the airfield.

After commissioning, a Constitution made an inaugural non-stop flight across the USA. One of the pair survives, languishing near Opa-Locka airport, Florida, as N7673C.

The first XR6O-1, 85163, lifts off from Burbank for its flight on November 9, 1946, after a take off run of only 1,820ft. Note the extended tail-bumper and the tandem pairs of main wheel units with twin legs.
