The 350th Air Refueling Squadron is a United States Air Force unit assigned to the 22nd Air Refueling Wing at McConnell Air Force Base, Kansas. It operates Boeing KC-135 Stratotanker aircraft conducting aerial refueling missions.
The squadron was originally established as one of the original Boeing B-17 Flying Fortress heavy bombardment squadrons of the 100th Bombardment Group in mid-1942 under Third Air Force but was immediately transferred to Second Air Force for training. It remained a paper unit until the initial cadre of the ground echelon (4 officers and 27 enlisted men) were assigned at Gowen Field, Idaho. Two days later, the squadron departed for Walla Walla Army Air Base, Washington for Phase I training. There the first aircrew arrived on 1 December 1942.
