Post-war, North American's employment dropped from a high of 91,000 to 5,000 in 1946. On V-J Day, North American had orders from the U.S. government for 8,000 aircraft. A few months later, that had dropped to 24.
Two years later in 1948, General Motors divested NAA as a public company. Nevertheless, NAA continued with new designs, including the T-28 Trojan trainer and attack aircraft, the odd-looking F-82 Twin Mustang, B-45 Tornado jet bomber, the FJ Fury fighter, AJ Savage, the revolutionary XB-70 Valkyrie Mach-3 strategic bomber, Shrike Commander, and T-39 Sabreliner business jet.
The Columbus, Ohio division of North American Aviation was instrumental in the exclusive development and production of the A-5 Vigilante, an advanced high speed bomber that would see significant use as a naval reconnaissance aircraft during the Vietnam War, the OV-10 Bronco, the first aircraft specifically designed for forward air control (FAC), and counter-insurgency (COIN) duties, and the T-2 Buckeye Naval trainer, which would serve from the late 1950s until 2008 and be flown in training by virtually every Naval Aviator and Naval Flight Officer in the US Navy and US Marine Corps for four decades. The Buckeye's name would be an acknowledgment to the state tree of Ohio, as well as the mascot of Ohio State University.
