 A government decision on whether to purchase a further 28 F-35s, to be based at Amberley, will depend on how long the Super Hornets are to be retained.According to "Australian Aviation", continuing delays to the F-35 program have increased the likelihood that the Super Hornets of Nos.1 and 6 Squadrons will, rather than being disposed of early as originally planned, continue to be operated by the RAAF for their full service life of over 20 years.
