....The Air Portable Fuel Containers Mk 5 are enormous rubber balls which enable essential fuel supplies to be delivered by air to more remote areas of operations.
The balloon-like containers, which hold up to two tonnes of fuel each, also contain the polymer Kevlar, a flexible plastic commonly used in body armour, to keep the contents protected from enemy fire.
Measuring 4.5 feet (1.37m) in diameter when full, the Mk 5 containers can be easily transported in a sling under a helicopter or in the back of a transport aircraft. The Kevlar protection means they can also be parachuted into locations or dropped from heights of up to 25 feet (7.62m).
