The Army Air Corps ordered 38 improved B-17Bs as B-17C in 1940. The B-17C changed from 1,000-hp to 1,200-hp Wright R-1820-65 radial engines. Flat sliding gun panels were installed instead of waist gun blisters, providing greater crew safety and cleaner design. The ventral gun blister was replaced by a "bathtub" turret also.

Twenty B-17Cs were transferred to the RAF (Fortress I), which used them during the early stages of World War II. The remaining 18 C models were modified to the D model configuration and became second line RB-17Ds late in their service lives.
