On 10 February 2016, a RAAF KC-30A Multi-Role Tanker Transport (MRTT) conducted its first air-to-air refuelling with a C-17A Globemaster III transport, flying from Edwards Air Force Base in California. The five-hour sortie saw 39 contacts between the KC-30A and C-17A aircraft, with approximately 6,800 kilograms of fuel transferred to the C-17A via the KC-30A’s Advanced Refuelling Boom System (ARBS). The trial is part of a series of flights being made by a KC-30A with a range of USAF aircraft, and is a precursor to refuelling the RAAF's own C-17As in the near future.
