In 1935, after the success of the Model 10 Electra, Lockheed set out to design a similar, but smaller, twin-engined aircraft. The resultant Model 12 was one of the first aircraft intended for business use, seating six passengers in a well-furnished cabin. A total of 114 were built before production ceased in 1942. The U.S. military also acquired a number of Model 12-As for transport duty, these being designated JO-1 and JO-2s for the U.S. Navy and Marines, and C-40s & UC-40s for the U.S. Army Air Corps. Military Model 12s were initially built in a seven-seat configuration. Sixteen armed versions (with two .50 caliber machine guns and underwing bomb racks) were also ordered by the Netherlands.
