The B-52G was proposed to extend the B-52's service life during delays in the B-58 Hustler program. At first, a radical redesign was envisioned with a completely new wing and Pratt & Whitney J75 engines. This was rejected to avoid slowdowns in production, although a large number of changes were implemented. The most significant of these was a new "wet" wing with integral fuel tanks, increasing gross aircraft weight by 38,000 pounds (17,235 kg). In addition, a pair of 700 US gallon (2,650 L) external fuel tanks were fitted under the wings on wet hardpoints. The traditional ailerons were also eliminated, and the spoilers now provided all roll control (roll control had always been primarily with spoilers due to the danger of wing twist under aileron deflection, but older models had small "feeler" ailerons fitted to provide feedback to the controls). The tail fin was shortened by 8 feet (2.4 m), water injection system capacity was increased to 1,200 US gallons (4,540 L), and the nose radome was enlarged. The tail gunner was relocated to the forward fuselage, aiming via a radar scope, and was now provided with an ejection seat. Dubbed the "Battle Station" concept, the offensive crew (pilot and copilot on the upper deck and the two bombing navigation system operators on the lower deck) faced forward, while the defensive crew (tail gunner and ECM operator) on the upper deck faced aft. The B-52G entered service on 13 February 1959 (a day earlier, the last B-36 was retired, making SAC an all-jet bomber force). 193 B-52Gs were produced, making this the most produced B-52 variant. Most B-52Gs were destroyed in compliance with the 1992 Strategic Arms Reduction Treaty; the last B-52G, number 58-0224, was dismantled under New START treaty requirements in December 2013. A few examples remain on display for museums.
