The airfield was attacked on numerous missions by Tenth Air Force and Royal Air Force fighter and bombers until it was captured by Merrill's Marauders (officially named the 6th Ranger Battalion-5307th Composite Unit (provisional)) on 17 May 1944, but fighting continued in Myitkyina town until August 1944.
Once in Allied hands, the 3d Combat Cargo Group moved in with C-47 Skytrains and used Myitkyina as a combat resupply airfield, air-dropping pallets of supplies and ammunition to the advancing Allied forces on the ground. In January 1945, the 80th Fighter Group flew P-47 Thunderbolts from the field until 24 May 1945. The 1st Combat Cargo Group then moved in with C-47s and remained until August when elements of the 4th Combat Cargo Group replaced them. The 4th CCG operated supply and passenger flights between the airfield and China until December 1945 when American forces pulled out of the area at the end of the war.
