The squadron operates six Airbus KC-30A Multi Role Tanker Transports, the first of which entered service in June 2011. A seventh, for VIP passenger transport as well as aerial refuelling, is due for delivery in 2019. The aircraft are crewed by pilots, refuelling operators and flight attendants. Air-to-air refuelling is considered a force multiplier, permitting the RAAF to increase the range and loiter time of its aircraft. The ability to refuel in flight also enables aircraft to take off with more ordnance than they might otherwise.
