    Defying physics... how, exactly?

    Australia has ordered a number of these planes at large cost. There have been constant problems and cost overruns. I'm not convinced it's worth every penny at this point.

    Australia hasn't ordered a single F-22. The Congress has not legalized their sale to our allies (even the close ones like Canada, the UK and Australia; which I would be okay with). The F-35 is, however, available to the US's partners.,

    maybe its the act of spending 200+ million on it

    What are the names of the F-22 and the F-35? Australia has ordered something called the "Joint Strike Fighter", I believe.

    the F-22 is the raptor. Its the one we SHOULD have bought insted of getting involved in the stupid F-35 joint strike fighter disaster

    In a way you never seen a plane to fly. Like going in a loop around its nose...

    The Russian jet's costs is only 20% of the American's, so Australians should have bought that ones against the aboriginals....

    If the Russian one is only 20% of the cost of F-22 how does that make F-22 worth every penny?

    It isn't: it's over-budget, under-spec and already out of production.
    Edit: that's the F-22.
    Oz has ordered the F-35 - which is having its own problems.

    interesting, i herd a debate in the senate (Australian) which critised the F35 sure but was quite complemtry of the F-22. Basically the way it went was that rather than replacing the F-18 hornates (which are falling apart NOW) with the F-35 which MAY or may not get working at some stage in the future we should be buying a plane which is on the shelves now and there for is reliable and efficent where as the F-35 (even if it does get delivered on time) will be the first batch and there for full of bugs

    The Joint Strike Fighter is not an F22 it is the F35.

    Wrong.
    The Joint Strike Fighter is a US/ UK initiative, (purely US at the start) with smaller participation from other nations.
    It is intended to replace F-16, A-10, F/A-18 (excluding newer E/F "Super Hornet" variants) and AV-8B.

    Europe doesn't want an F-22 equivalent - too pricey.
    For example the UK has Typhoon Eurofighter (80% of the capability for 50% of the cost, roughly), France has Rafale.

    Edit: I just noticed that Grim Reaper deleted the post I quoted.
    I'll leave mine just for background info.

    True, but that sort of maneuverability doesn't actually matter that much in modern air-to-air combat. It's now mostly about your plane's top speed, rate of climb, radar cross-section, and avionics.

    Part of the reason why the F-22 is so much more expensive than the Su-30 is that the F-22 uses a very sophisticated solid-state radar system that costs tens of millions all by itself. The radar spreads its beam over a wide swath of the radio spectrum so that each individual wavelength is being emitted at a very low power, and it can continuously vary what swath of the spectrum it's using. This makes it extremely hard for other planes etc. to detect when they're being illuminated by it, because it's very difficult to separate the radar's radio signals out from the background radio noise.

    First off, Australia never even had the "option" of getting involved with the F-22. It was a wholly American project, one that was restricted away from anybody else from day one.

    Second off, the Joint Strike Fighter is the second generation that the USA decided to undergo to (a) help/involve our allies and (b) save a boat load of money on.

    While the F-22 is truly an amazing aircraft, it's amazing-ness is dulled down when compared to the "bang for your buck" that the F-35 delivers at significantly lower costs. I do love the F-22, but it's so ungodly expensive and cranky, that--despite the pain of losing it--the USA should stop production and go forward with the F-35 (the "Joint Strike Fighter").

    Hmm, F-35.
    Costs were predicated on sales of 7,500 IIRC (of all variants -A, -B & -C) and so far there are orders (including MoU [Memoranda of Understanding - i.e. not firm commitments to buy]) of just under 2,5000. Which will increase unit flyaway costs.
    Here.
    Also:
    Not only more expensive to buy, but more expensive to operate.

    Here.

    And a quote from me: this is my entry in my list of photos that I took at Farnborough one year.
    Every time they run into increased costs they seem to decide on cutting capability to reduce those costs.
    Given that cost increases are inevitable anyway eventually they'll end up with a fairly expensive aircraft that can't do anything...

    The Russian one is worths every rubel. It is just a saying, you know...

    Actually it isn't a contradiction, because if you can buy only one kind, it doesn't matter that it is aviable for cheaper somewhere else.

    By the way I agree these are just impressive toys but in modern warfare a drone is more useful...

    The total cost of the F-22 is around 500 million when we add the R&D divided by the number of planes planned to be made...
