The Navy's B-17G variant included additional fuel tanks for longer-range missions
The B-17 Flying Fortress, a heavy bomber used by the United States Army Air Forces during World War II, had a range of variants. The Navy's B-17G variant was one such version, which included additional fuel tanks for longer-range missions.
During the final year of World War II and shortly thereafter, the United States Navy acquired 48 ex-USAAF B-17s for patrol and air-sea rescue work. The Navy obtained a B-17F (later modified to B-17G standard) and a B-17G for various development programs. These aircraft were initially designated PB-1, and 32 B-17Gs were used by the Navy under the designation PB-1W, indicating an airborne early warning role.
The B-17G variant of the Flying Fortress featured additional internal fuel tanks, with provisions for extra underwing fuel tanks, allowing for extended range. The B-17G also incorporated all changes made to its predecessor, the B-17F, including an increase in the number of guns from seven to 13.
The B-17G's internal fuel tanks added to the aircraft's range, addressing the B-17's previously shorter range compared to other aircraft. This range extension was further enhanced by the installation of Tokyo tanks, which added approximately 900 miles to the bomber's target capability.
The Navy's B-17G variant, with its additional fuel tanks, contributed to the versatility of the B-17 platform, showcasing its adaptability to different mission requirements and its enduring legacy in military aviation.

A typical B-17G consumes 2200 US gallons of fuel on a mission to Eastern Germany
The B-17 Flying Fortress, manufactured by Boeing, was a versatile aircraft that played a significant role in World War II. It was widely used by the USAAF and, to a lesser extent, the RAF, particularly in the European theater. The B-17G was the final iteration of the aircraft, with improvements over its predecessor, the B-17F, including an increased number of guns and finalized gun station designs. A total of 8,680 B-17Gs were built, with the last one completed on July 28, 1945.
The B-17G, like its previous versions, was renowned for its durability and stability. It had a shorter range and could carry a smaller bomb load compared to other aircraft, but its performance and survivability were highly regarded. This particular version, the B-17G, could consume around 2,200 US gallons of fuel on a mission to Eastern Germany. This fuel consumption was necessary to power the aircraft over long distances and enable it to carry out its strategic bombing missions effectively.
The B-17's fuel consumption was not only dependent on the distance travelled but also on the weight of the aircraft. A heavier aircraft, loaded with bombs and ammunition, would consume more fuel than one on a reconnaissance mission with a lighter load. Additionally, factors such as headwinds or evasive maneuvers during combat could further impact fuel usage.
To enhance the B-17G's range for specific missions, additional internal fuel tanks were sometimes installed, and provisions were made for underwing fuel tanks. These modifications allowed the aircraft to fly further and remain airborne for extended periods, increasing its operational flexibility.
The B-17 Flying Fortress left a lasting legacy, with its durability and performance playing a crucial role in the war effort. Even after World War II, the aircraft continued to serve in various capacities, including air-sea rescue, engine testing, and atmospheric sampling during atomic bomb tests. Today, only a handful of B-17s remain operational, preserved in museums and collections, reminding us of their significant contribution to aviation history.
