The military versions of the popular civilian Model 18. The AT-7 was the Army Air Forces' first dedicated navigation trainer and featured a rotatable astrodome behind the cockpit. The AT-11 featured a glass nose, Norden bombsight, and a bomb bay and was used to train 90 percent of World War II bombardiers. Both types were first purchased in 1941. The C-45 was used as a utility transport and for advanced training. The F-2, like the C-45, was first purchased in 1940 and was the AAF's first specialized mapping and photoreconnaissance aircraft and featured up to four fuselage-mounted cameras. These aircraft also had uprated engines and an oxygen system for the crew. This aircraft type also saw service with the US Navy as the JRB (C-45) and SNB (AT-7/AT-11). Approx 900 USAF aircraft (mostly C-45s) were remanufactured by Beech in Herington, Kan., after the war. The C-45G/Hs (the remanufactured aircraft) stayed in USAF use until 1963.
