It was originally assigned the Victor (unit-assigned identification) number 6 but on 1 August was given the triangle N tail markings of the 444th Bomb Group as a security measure and had its Victor changed to 86 to avoid misidentification with actual 444th BG aircraft. It was named Next Objective and its nose art applied after the atomic bomb missions.
While at Tinian, Devore and crew A-3 flew Next Objective on 12 practice bombing missions and three pumpkin bomb missions against Japanese industrial targets at Toyama, Niihama, and Nagoya, and one which was aborted. Major Charles Sweeney, commanding officer of the 393d BS, used the bomber to rehearse procedures using a dummy "Little Boy" test assembly on 26 and 29 July. On the latter mission Next Objective landed on Iwo Jima where the inert bomb was unloaded, then reloaded to practice a contingency in which a spare aircraft would take over the mission.
On 25 May 1949, 44-27299 was assigned to a navigation training mission. Shortly after takeoff an engine fire broke out in the right outboard engine, resulting in a crew bailout. The navigator assigned struck his head on the machinery that operated the nose landing gear as he exited the aircraft and was killed when his parachute did not deploy. The pilotless Next Objective circled in a two-mile orbit before crashing 35 miles northeast of El Paso, where it exploded on impact.
Other aircraft named Next Objective
Two FB-111A strategic bombers of the USAF 509th Bomb Wing, serials 68-0257 and 68-0284, carried the name Next Objective on their nosewheel doors, and 68-0257 carried the B-29 nose art, while based at Pease Air Force Base, New Hampshire, in the 1970s and 1980s.
