The B-52G was a designed to reduce the overall aircraft weight in an effort to improve performance. The most obvious change was the redesigned tail. About eight feet of the vertical stabilizer was removed and the chord (width) was increased. The wing was extensively modified also. The seal-sealing bladder-type fuel cells were removed and the wing itself was sealed for fuel (wet wing). The tail gunner's position was moved from the tail turret to a remote firing station in the forward crew compartment.
Boeing (Wichita) built all 193 B-52Gs with the first aircraft rolling out of the production plant in the summer of 1958. The G model was capable of carrying two AGM-28 "Hound Dog" missiles like the F model, but it was also equipped to carry the GAM-87 "Skybolt" and later the Air Launched Cruise Missile and the Short Range Attack Missile.
The B-52G was used extensively in the 1991 during Operation Desert Storm before being phased out of operational service in 1994.
