Royal Australian Air Force F-35As Train for In-Flight Refueling to Prepare IOC

Eagle-eyed residents have spotted high-flying Royal Australian Air Force (RAAF) training missions over Taree on the NSW mid-north coast. A local Facebook page featured images shot by a Taree resident of a Airbus KC-30A multi-role tanker transport conducting air-to-air refuelling with a pair of F-35A Lightning II fighter aircraft. Commanding Officer of No. 33 Squadron, Wing Commander Sarah Stalker, said skies over the area were frequently used for training. RAAF often use a block of airspace, which allows aircraft from Williamtown and Amberley to ‘meet in the middle’ when training. Air-to-air refuelling is usually conducted at an altitude of 20,000 feet or more, so will often go unnoticed by the local community.

The KC-30A is a converted Airbus A330 airliner, and the RAAF operates a fleet of seven of these aircraft. While the KC-30A’s interior is almost exactly like a normal airliner, the rest of the aircraft has been modified with systems to perform the air-to-air refuelling. The KC-30A can carry more than 100 tonnes of fuel and have two methods of offloading that fuel to another aircraft. The receiver aircraft will need to maintain a precise formation with the tanker whilst they fly together at 600 kilometres per hour. The receiver aircraft will either ‘plug in’ to a hose-and-drogue being trailed out by the tanker, or be ‘plugged’ by the refuelling boom on the tanker, depending on the refuelling system of the receiving aircraft.

The Airbus KC-30’s boom can offload fuel at a rate of 4500 litres a minute and its hose-and-drogues can offload fuel at 1600 litres a minute. An air refuelling operator uses a console in the cockpit and 3D monitors to direct the refuelling process behind the aircraft. Regular training and precise skill from the tanker crew and receiver pilot is necessary for safe air-to-air refuelling, however, this training activity presents very little risk to the wider public. Typically, there is no fuel that escapes during each airborne refuel, and if fuel is released, it evaporates into the atmosphere, rather than falling directly onto the ground.

Regular training ensures the RAAF is able to respond to events at short notice and travel long distances. Anyone who has flown over Australia or overseas can appreciate the long distances that need to be covered to get somewhere, and the RAAF is no exception. Air-to-air refuelling isn’t just limited to our fighters – RAAF can use it to keep surveillance aircraft in the air for longer, and even refuelled other transport aircraft. In 2017, RAAF refuelled a RAAF C-17A Globemaster on a non-stop mission from Tasmania to air-drop supplies in Antarctica – a round-trip of 7000km. The current round of air-to-air refuelling training is expected to continue high above the mid north coast of NSW until June 25.
