Eagle-eyed photographer snaps rare bird formation

Eagle-eyed residents in Taree on the NSW mid-north coast have spotted high-flying Air Force training missions – with a local photography enthusiast posting images of a KC-30A multi-role tanker transport conducting air-to-air refuelling with a pair of F-35A Lightning II fighter aircraft on Facebook.

Commanding Officer of No. 33 Squadron Wing Commander Sarah Stalker said skies over the area were frequently used for training.

“We’ll often use a block of airspace that extends from Williamtown to Coffs Harbour, which allows aircraft from Williamtown and Amberley to ‘meet in the middle’ when training,” Wing Commander Stalker said.

“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.”

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 that allow it to perform the air-to-air refuelling role.

“We can carry more than 100 tonnes of fuel and have two methods of offloading that fuel to another aircraft,” Wing Commander Stalker said.

“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 KC-30A’s boom can offload fuel at a rate of 4500 litres per minute and its hose-and-drogues can offload fuel at 1600 litres per minute.

An air refuelling operator uses a console in the cockpit and 3D monitors to direct the refuelling process behind the aircraft.

Wing Commander Stalker said regular training and precise skill from the tanker crew and receiver pilot are necessary for safe air-to-air refuelling, however this training activity presents very little risk to the wider public.

“We conduct a lot of this training away from built-up areas, in airspace that is away from where other aircraft will be flying.

“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 of this nature ensures the RAAF is able to respond to events at short notice and travel long distances.

The current round of air-to-air refuelling training is expected to continue high above the mid north coast of NSW until June 25.
