The two additional KC-30A aircraft will be delivered in 2018 and provide a substantial increase to the air-to-air refuelling capacity of the RAAF.
Defence has signed an update to the existing acquisition contract with Airbus Defence and Space for the two aircraft and associated conversion at a cost of approximately AUD $408m.
Each KC-30A has a fuel capacity of more than 100 tonnes, and can offload fuel via the 17-metre-long Aerial Refuelling Boom System or the two hose-and-drogue refuelling pods.
The aircraft is capable of refuelling F/A-18A/B Hornets, F/A-18F Super Hornets, E-7A Wedgetail, C-17A Globemasters and other KC-30A aircraft.
In the future it will refuel EA-18G Growler, P-8A Poseidon and the F-35A (Joint Strike Fighter) providing a force-multiplier so aircraft can remain on station longer, extending their range and persistence.
The KC-30A continues to play an important role in the Middle East region as part of Operation OKRA, refuelling both a growing number of Australian and Coalition fighter aircraft.
Since September 2014, the KC-30A deployed to Operation OKRA has delivered more than more than 10,800 tonnes of fuel.
The additional two aircraft will be based at RAAF Base Amberley, increasing our KC-30A fleet to seven.
