There will never be a replacement for the raptor, not in my lifetime at least. It was/is the replacement for the 30 year old F-15, the dominate air to air fighter of the world, and a darn good one at that. Washington plans on the F-35 JSF to do the job. The two platforms are not even comparable. The F-22 is a stealth, vectored thrust, supersonic cruiser that ensures air superiority. IMO, the Raptor was too good for its own good. The USAF refused to allow the sale of the Raptor to ANY foreign service, not even Israel. The F-35, on the other hand, is supposed to make all the services happy and be a major player on the international arms sale stage. Everyone makes more money...... Hopefully we'll never go to war with an enemy flying 5th generation Sukois.
