The KC-30A is the Royal Australian Air Force (RAAF) designation for the Airbus Defence and Space A330 Multi Role Tanker Transport (MRTT).
The aircraft is a military conversion of the A330 airliner, capable of carrying up to 110 tonnes of fuel without sacrificing space in either the passenger cabin or cargo hold. In service with Saudi Arabia, United Arab Emirates and the Royal Air Force, Airbus also has orders from Korea, Singapore and France.
The Australian KC-30 differs from the RAF Voyager in that is equipped with the Aerial Refuelling Boom System, as well as two hose and drogue wing pods. The 'boom' allows the KC-30A to refuel fighters such as the F-15 and F-16 and larger aircraft including the P8A Poseidon and the E-7 Wedgetail, both of which are in service with the RAAF.
Air Tattoo 2016 marks the first time an RAAF KC-30A has visited a UK airshow. The RAAF last attended the Air Tattoo in 2006 with a Boeing 707, provided then by 33 Squadron.
