Operations on Tinian

In early 1945, the massive American base being constructed at North Field, Tinian, was selected to be the operational base for the 509th. Subsequently many of the group's pilots flew to Tinian on ATC planes to familiarize themselves with the routes to be flown by the units Boeing B-29 Superfortresses and C-54s. The short-legged C-47s would remain at Wendover.Ossip All through April 1945, the group's ground echelon was processed for overseas deployment.

At Wendover, Major Sweeney was transferred to be the commander of the 393d Bombardment Squadron and he was replaced by Captain John J. Casey, Jr. In May 1945 the squadron moved to North Field, Tinian, transporting men and materiel of the 509th group as the group moved to its operational base. For the reason that freight took priority over passengers, the rear air element of the 320th remained at Wendover, and flew the squadron's C-47s to ferry necessary equipment to the base, which would be transshipped to Tinian on the C-54s.

Operation Crossroads

Finally in November with the mission on Tinian completed, the squadron moved to Roswell Army Air Field, New Mexico in the fall of 1945. Although it remained active, demobilization resulted in the loss of almost all squadron personnel. The unit was, however, manned and equipped to enable it to participate in atomic testing. During

the squadron operated as Air Transport Unit 1.54 (Provisional). Prior to the weapons drop, it transported personnel and material (including radiological test samples) to support the testing. When special observation aircraft failed to arrive in the Kwajalein Atoll test area seven days before the test, the squadron substituted for them. On the first and second day after testing, the 320th flew scientists and high-ranking personnel on low-level observation flights over the test area.


Inactivation

The 320th Troop Carrier Squadron was inactivated on 19 August 1946. The mission, however remained and its equipment and personnel were transferred to the 1st Air Transport Unit, which was organized on 10 July at Roswell.
