Boeing (Martin) JTB-29J 44-86402 X-7 Mothership

These are 1/72 scale decals for Boeing (Martin) JTB-29J 44-86402, serving as a mothership for the Lockheed X-7 program, United States Air Force.

The Lockheed X-7 was an unmanned ramjet-powered test vehicle developed in the 1950s to evaluate ramjet propulsion and aerodynamics at high speeds — research directly relevant to the development of supersonic missiles and early hypersonic flight. The JTB-29J was a specially modified B-29 configured to carry and air-launch the X-7 from altitude, acting as the airborne platform for these cutting-edge propulsion experiments.

As a mothership, 44-86402 represents a fascinating and highly specialized corner of postwar American aerospace research — a wartime heavy bomber repurposed at the frontier of the jet and missile age. A unique subject for modelers interested in experimental aircraft and Cold War-era test programs.
