Last week the US House of Representatives voted to allow US allies to potentially purchase the F22. The US Senate has not voted on Representative K. Grangers amendment yet but as the Washington Post notes, the Senate has normally been more tolerant of international involvement in US military programs.
As noted in a Parliamentary Research Note on the JSF [pdf] the APH covered the options for Australia should the JSF project prove sub-optimal.
The two options offered were the F22 and the F15K variant.
The F22 is very expensive, currently thought to be in the area of 200 million USD each, but
Maj. Gen. Richard B.H. Lewis claims the next production run of one hundred F22s will bring the unit cost down to 116 million per aircraft.
That makes it cost competitive with the JSF which is thought to currently cost somewhere between 95 million and 100 million. ..
While the government re-affirmed its support for the JSF project, the interesting political statements came from the other side of parliament. Both Kim Beazley and Robert McClelland made statements saying that Australia should seriously look at purchasing the F22 to plug the projection hole.
For instance McClelland;
... we will
closely examine the option of
acquiring F-22 Raptors, at least in the initial procurement phase, to ensure Australia does not forfeit regional air superiority between retirement of the F-111s in 2012 and delivery of replacement JSFs in 2015 at the earliest and more likely 2017.
And Beazley a couple of days later;
It's a very serious situation. A big capability gap is building up now - Australia versus the region ... We have always enjoyed technological superiority. We are now about to lose it. ..
The procurement of the F22 would send a large message of Australian power, seriousness, deterrence and prestige.
