Twenty-two B-36As were built in four production blocks. The -A model featured the domed canopy first seen on the YB-36 and a redesigned four-wheel main landing gear system that replaced the single-wheel main landing gear of the two earlier aircraft (XB-36 and YB-36).

The first flight of the B-36A was on Aug. 28, 1947. The -A model actually flew six months earlier than the YB-36, but this was because the first production B-36A (S/N 44-92004) was completed with just enough equipment to make a ferry flight to Wright Field, Ohio. Once at Wright Field the aircraft was used as a test bed for structural tests. These tests were often conducted to test maximum loads until structural failure occurred. Thus, the first B-36A was destroyed.

Although the B-36A was technically a production aircraft, no defensive armament was installed. The -A model was used by the 7th Bomb Group at Carswell Air Force Base, Texas, for crew training and testing only.
