The Boeing F/A-18E and F/A-18F Super Hornet are twin-engine, carrier-capable, multirole fighter aircraft variants based on the McDonnell Douglas F/A-18 Hornet. The F/A-18E single-seat and F/A-18F tandem-seat variants are larger and more advanced derivatives of the F/A-18C and D Hornet.
The Super Hornet has an internal 20 mm M61 rotary cannon and can carry air-to-air missiles and air-to-surface weapons. Additional fuel can be carried in up to five external fuel tanks and the aircraft can be configured as an airborne tanker by adding an external air-to-air refuelling system.
📑 ➖➖➖ On 3 May 2007, the Australian Government signed a A$2.9 billion contract to acquire 24 F/A-18Fs for the Royal Australian Air Force (RAAF) as an interim replacement for its ageing F-111s. It was reported, in July 2007, that the order for the F/A-18F would also prevent, in the event of significant delays to the F-35 program, any difficulties that might be caused by a need to quickly replace the RAAF's existing fleet of "Classic Hornets" (F/A-18A/B). The total cost of the Super Hornet purchase, with training and support over 10 years, was expected to be A$6 billion (US$4.6 billion). The Block II package aircraft offered to the RAAF include installed engines and six spares, APG-79 AESA radars, Link 16 connectivity, LAU-127 guided missile launchers, AN/ALE-55 fibre optic towed decoys and other equipment. The government has also sought U.S. export approval for Boeing EA-18G Growlers. On 27 February 2009, Fitzgibbon announced that 12 of the 24 Super Hornets would be wired on the production line for future modification as EA-18Gs. The additional wiring would cost A$35 million. The final decision on conversion to EA-18Gs, at a cost of A$300 million, would be made in 2012. The first RAAF Super Hornet was completed in 2009 and first flew from Boeing's factory in St. Louis, Missouri on 21 July 2009. RAAF crews began training in the U.S. in 2009. The RAAF's first five F/A-18Fs arrived at their home base, RAAF Base Amberley in Queensland, on 26 March 2010; and were joined by six more aircraft on 7 July 2010. Following the arrival of another four aircraft in December 2010, the first RAAF F/A-18F squadron was declared operational on 9 December 2010. In December 2012, the Australian government sought information from the United States about the cost of acquiring a further 24 F/A-18Fs, which may be purchased to avoid a capability gap due to F-35 program delays. In February 2013, the U.S. Defense Security Cooperation Agency notified Congress of a possible Foreign Military Sale to Australia for up to 12 F/A-18E/F and 12 EA-18G Growler aircraft with associated equipment, training and logistical support. In May 2013, Australia announced they would retain the 24 F/A-18F instead of converting them and will order 12 new EA-18Gs. In June 2014 Boeing was awarded the contract for the 12 EA-18Gs, and the first EA-18G for Australia was rolled out on 29 July 2015.
