After the end of World War II, large numbers of Beech C-45 Expeditors were kept and used as light transport, training and liaison aircraft. In 1951 the Air Force authorized a large upgrade program for several hundred C-45, AT-7 and AT-11 aircraft.

During the major overhaul process, the planes were completely torn down and inspected. Worn and damaged parts were replaced along with several planned upgrades. The center wing section was replaced with a new and stronger assembly. The landing gear was replaced with a stronger version. The propellers were replaced by constant speed, feathering models. The instruments were replaced and in many cases, upgraded to more modern versions. Finally, an autopilot system was added.

Because of the extensive modifications done to the aircraft, all were re-designated as C-45G and assigned new 1951 serial numbers. A total of 372 aircraft were converted and continued to serve the USAF throughout the 1950s and into the 1960s, gradually being transferred to Air National Guard units.

A separate, but similar program was established in 1951 to convert 96 C-45s to navigation trainers. These aircraft had most of the same upgrades as the C-45Gs and also had an interior upgrade to accommodate a pilot, co-pilot/navigator instructor and three navigator students. These aircraft were designated as TC-45G.
