Eleven B-50Ds were modified as crew training aircraft and redesignated TB-50D. All armament was removed and special equipment used to train crew members was installed. The aft bomb bay was replaced by an electronics bay housing most of the additional avionics used in training.

The primary mission of the TB-50D was to train navigator-radar operator-bombardier triple duty crewmen. Since most of the bombers of the early 1950s had relatively small crews, many crew members had to do more than one job.

The forward fuselage compartment was used to conduct navigator training. One instructor and two student stations for were installed. The aft fuselage was modified for radar operator training and also had seats for one instructor and two students.

Bombardier training was generally conducted with a trainer or operational version of the specific aircraft the crewman would fly operational missions in.
