In the 1940s the airport handled war materials for the former adjacent New Cumberland Army Depot and hosted the Naval Photographic Reconnaissance Training School. The Army Air Corps stationed the 101st and 103d Observation Squadrons at Harrisburg early in the war to train pilots in observation and aerial photography. Later the Army Air Force formed the 6th Fighter Wing and 47th Bombardment Wing at the airport before their deployment overseas. New Cumberland Army depot remains although it has gone through several name changes over the years. It has been known as Defense Distribution Center (DDC) New Cumberland, Defense Distribution Region East (DDRE), and the Defense Distribution Supply Point (DDSP) Susquehanna. Currently it is known as the Defense Logistics Agency (DLA) Susquehanna, one of the largest military distribution centers for supplies and equipment for the U.S. Armed Forces
