Consolidated Vultee received an order to build 1,100 TBY-2 Sea Wolf torpedo bombers for the Navy. However, production delays of almost a year caused the first aircraft to come off the line at Plant 5C on 20 August 1944, and the first production aircraft to be delivered to the Navy on 7 November. By this time, the usefulness of the plane became limited as the Grumman TBF Avenger was the primary torpedo bomber in combat, equipping all Navy torpedo squadrons. Subsequently, only 180 TBY-2s were produced and none saw combat, being used as trainers by the Navy in the United States. With the end of the war in 1945, aircraft production was shut down. Plant 5C was returned to Mack Trucks and the remainder of the facility was declared surplus by the War Assets Administration. Civil airport On 10 July 1947, ownership of Convair Field was transferred from the federal government to the City of Allentown. As part of the transfer, the City agreed to keep it open as an airport and as an emergency landing field. In 1948, the Pennsylvania Air National Guard signed a lease to take over the aviation facilities for flight training in support of the 148th Fighter Squadron at Reading Airport. During the 1950s, a series of training exercises was carried out at Convair Field. Due to budgetary cutbacks the Reserve Training Center at Reading was inactivated on 1 May 1950 and reassigned to New Castle County Airport, Delaware. The Air Force closed its facilities at Reading Airport and it returned to civil control. In 1951, the Air National Guard facilities in Allentown were turned over to Air Products and Chemicals. Air Products paid $12,000/year in rent and that money was used to maintain the airport. The runways were used by the Allentown Jaycees for drag racing in order to get "hot rods" off the city streets. This did not last long, due to objections by local residents and also by the CAA as the runways were not being used by aviation. During the 1950s several plans were made to re-develop the land, but all never materialized due to the aviation clause in the transfer document to the City of Allentown in 1947. In 1961, the City of Allentown took over full control of the facility and renamed it "Queen City Airport". Aviation facilities were contracted to Reading Aviation for operation of the airfield. In
