The B-25C was an improved version of the B model featuring improved Wright R-2600-13 radial engines, deicing and anti-icing equipment, a sighting blister for the navigator and increased nose armament of one fixed and one flexible .50-cal. machine gun. The -C model was the first mass produced B-25 version and 1,625 were built with 1941 and 1942 serial numbers. The B-25C was also used by Great Britain as "Mitchell II," the Netherlands, China, Russia and Canada (later models were used by Brazil and Australia).
A few B-25Cs were modified for special purposes or to become prototype test-bed aircraft. One was modified for use as a staff transport by Gen. Henry H. "Hap" Arnold and was redesignated RB-25C. Three more aircraft were modified and redesignated XB-25E, F and G while another became the prototype B-25H. Five more aircraft were rebuilt to become the first production B-25Gs.
