On display at Udvar-Hazy. Shortly after delivery on 6 Nov 1943, this P-38J was converted to a two-seat trainer, spending its time at Wright Field as an experimental aircraft. It was flown there on 16 Apr 1945 by Maj. Richard I. Bong, America's highest scoring fighter ace. He had planned to fly for an hour but the right engine blew up, cutting the test short. On 20 Jun 1945 it was earmarked for storage as a museum aircraft. The J had redesigned oil cooler intakes and larger radiator scoops. Turbo-supercharger cooling intakes on top have replaced the carburetor air scoop on earlier models.

Built at Lockheed's Burbank plant in November 1943 and used in various test and development roles during WW2 and then stored. It has never been repainted. Serial repeated under port wing leading edge.

This P-38 never saw combat, rather was allocated to be an experimental airframe at Wright Field, OH and then at the end of WWII it was placed into storage. It is now on display with this unrestored finish at the super NASM Udvar-Hazy center.
