Let me ask you, what threat do you see the US facing in the next 5 years that would need 100 more F-22's? China and the J20? If you remember it took the us 6 years to go from first-flight to production. By the time China is fielding the J-20, the US will be probably putting 2+ UCAV's in production. China is playing games with the J-20 making the US scared.
Nothing like a threat from China to get the lobbiest scaring the public, and President, up!
Same thing happed with the US/Russia Cold War, when the US said their was a "missile gap" when in fact, it was purposely blown out of proportion to buy more weapons systems.
Also, how is China going to threaten the US when they have been talking about a Carrier for the past 8 years, and again this year? Are Chinese J-20's going to fly the entire Pacific? No, it is to counter regional threats, Russia and India and the PAK FA.
It's Defense "smoke-and mirrors" from the Military Industrial Complex. Like I said on another thread. The US Defense Budget, that was just signed by Obama, is up 7%.
The US Army has been trying to kill the, Air Arm part of the Navies’ Army, from day one and they haven’t succeeded yet. The Marine air arm has had a good record no matter what they have been called upon to do. Better, man for man and plane for plain, than the US air force. But the final reason why this will never happen is what the Marine Air dose better than anyone else in the world including the much hyped Israeli Air Force, and that is to provide close air support for closely engaged ground troops, where they have always made a big difference in the number of US infantry causalities. Just ask any ground pounder that has called in an air strike close to friendly troupes, which they prefer every time.
As to the other part, I agree that the Chinese J20 is over hyped, both in when it will be operational and in its abilities, (Big plane big target). But it is what we eventually perceive is the Chinese goverments intentions, (righty or wrongly) not their hardware that will be the deciding factor and that question is still open. Just one deadly Incident ,even if unintended, could cause a change of direction on either side. I am not predicting this will happan; I am only saying things like this have happened before. In the final analyses it is about trust and that is in short supply.
