Assigned to Crew B-6 (Captain John A. Wilson, Aircraft Commander), Jabit III was flown to its home base at Wendover Army Air Field, Utah, in April 1945, departing Wendover for North Field, Tinian on June 5, 1945, arriving on June 11.

Jabit III was originally assigned the Victor (unit-assigned aircraft identification) number 1 but on August 1 was given the large 'A' tail markings of the 497th Bomb Group as a security measure and had its Victor number changed to 71, to avoid misidentification with actual 497th BG aircraft.

Jabit III was used by the group commander, Col. Paul Tibbets, on July 24 and 25 to drop two dummy Little Boy atomic bomb assemblies into the ocean off Tinian to test fire their radar altimeter components.

The aircraft had been unnamed when it left Tinian but was possibly given a name and nose art during its return to the United States.

Crew B-6 (regularly assigned to Jabit III) Two FB-111A strategic bombers of the USAF 509th Bomb Wing, serials 67-7193 and 68-0258, carried the original nose art of Jabit III on their nosewheel doors while based at Pease Air Force Base, New Hampshire, in the 1970s and 1980s.
