The B-50D was an improved version of the B-50B. Changes included the addition of two 700-gallon fuel tanks mounted on outboard wing pylons, and a redesigned nose compartment "greenhouse" with an improved bomb sight window. Most of the D models were fitted with in-flight refueling receptacles also.

The USAF received 222 D models with the first being delivered in the summer of 1949. B-50s served with the Strategic Air Command as medium bombers between 1949 and 1954 when they were replaced by jet-propelled B-47s. Many were modified for other roles such as weather reconnaissance, crew training, photo-mapping and aerial refueling. In these support roles, some B-50s remained in service until the late 1960s.
