A self-sealing fuel tank (SSFT) is a type of fuel tank, typically used in aircraft fuel tanks or fuel bladders, that prevents them from leaking fuel and igniting after being damaged. Typical self-sealing tanks have layers of rubber and reinforcing fabric, one of vulcanized rubber and one of untreated natural rubber, which can absorb fuel when ...
Tokyo tanks were internally mounted self-sealing fuel tanks used in the Boeing B-17 Flying Fortress and Consolidated B-24 Liberator bombers [1] during World War II.The tanks increased the B-17's total range at combat weight with 4,000–5,000 pounds (1,800–2,300 kg) of bombs by about 1,000 miles (1,600 km) and the combat radius was doubled to about 650 miles (1,050 km).

A major problem with welded aluminium tanks is weld decay and metal fatigue in the seams due to vibration in service. In response to this, the company started to develop flexible fuel bladders in the early 1940s. One of the earliest examples of this was a composite flexible fuel bladder with self-sealing coatings for the Supermarine Spitfire MkIX.
The engine was in the rear of the hull side by side with two self-sealing fuel tanks, of 100 and 410 litres respectively, separated from the fighting compartment by a firewall bulkhead. The nominally 200 hp engine, designed by Javier-Sabin, drew fuel from the smaller tank, which was itself automatically replenished from the larger one.
The fuel tanks, as was standard for Italian multi-engined aircraft, were metal self-sealing fuel tanks using materials developed by SEMAPE, the specialized manufacturer. Eight tanks were fitted, with six in the centre wing (4 × 150 L/40 US gallon and 2 × 1,140 L/301 US gal tanks) and two 370 L (100 US gal) tanks (or 780 L/210 US gal with ...
