The Royal Australian Air Force operates five KC-30A Multi Role Tanker Transports (MRTT), which are a heavily modified Airbus A330 airliner used for air-to-air refuelling and strategic transport. The KC-30A is able to refuel Air Force's F/A-18A/B Hornets and F/A-18F Super Hornets, as well as the E-7A Wedgetail Airborne Early Warning and Control aircraft, C-17A Globemaster III, and other KC-30As. It will be compatible with refuelling the P-8A Poseidon surveillance aircraft and F-35A Lightning II when these aircraft enter Air Force service.
The aircraft are fitted with two forms of air-to-air refuelling systems - an Aerial Refuelling Boom System mounted on the tail of the aircraft, which comprises a 'fly-by-wire' boom refuel system; and a pair of all-electric refuelling pods underneath each wing, which unreel a hose-and-drogue to refuel probe-equipped aircraft. These systems are controlled by an Air Refuelling Operator in the cockpit, who can view refuelling on 2D and 3D screens.
The KC-30A has a fuel capacity of more than 100 tonnes, and can remain 1800km from its home base with 50 tonnes of fuel available to offload for up to four hours. In its transport role, the KC-30A will be capable of carrying 270 passengers, comes with under-floor cargo compartments and will be able to accommodate 34,000kgs of military and civilian cargo pallets and containers.
Advanced mission systems will also be fitted. They include the Link 16 real-time data-link, military communications and navigation suites, and an electronic warfare self-protection system for protection against threats from surface-to-air missiles.
The KC-30As are operated by No 33 Squadron located at RAAF Base Amberley.
