Airbus Defence and Space has demonstrated automatic air-to-air refueling of a large aircraft. The company’s own A310 development tanker made seven contacts with an approaching A330 Multi-Role Tanker Transport (MRTT) owned by the Royal Australian Air Force (RAAF). Airbus previously demonstrated automatic refueling of a fighter aircraft. The A330 MRTT is designated KC-30A in service by the RAAF.
