The Navy used the B-17G, with extra fuel tanks for longer-range missions
The Navy used a modified version of the B-17G, known as the PB-1W, which featured additional fuel tanks to extend its range. Thirty-two of these aircraft were utilised by the Navy, painted in the standard dark blue colour scheme adopted in late 1944. The B-17G was chosen as the basis for this variant due to its heavy defensive armament, which was removed in the PB-1W variant to accommodate the extra fuel tanks and equipment.
The PB-1W was fitted with a large radome underneath the fuselage to house an S-band AN/APS-20 search radar, enhancing its airborne early warning capabilities. This modification, along with the additional fuel capacity, made the PB-1W well-suited for long-range missions. The exact amount of additional fuel that could be carried in these tanks is not readily available, however, the standard fuel capacity of the B-17G was likely augmented significantly to facilitate extended operations.
The B-17, affectionately known as the "Flying Fortress," played a crucial role during World War II, serving in every combat zone. Its versatility and adaptability were key factors in its widespread adoption by various branches of the military, including the Navy. The extended range provided by the additional fuel tanks in the PB-1W variant further enhanced the capabilities of the B-17, allowing it to undertake longer missions and contribute to its reputation as a reliable and formidable aircraft.
The PB-1Ws served in the USN until 1955 when they were gradually phased out in favour of the Lockheed WV-2, a military derivative of the Lockheed 1049 Constellation commercial airliner. Despite the eventual transition to newer aircraft, the modified B-17Gs with their extended fuel capacity played a significant role in bridging the technological gap, ensuring that the Navy could continue to meet its operational requirements during that period.
