Good point - and I was having that same argument in my head even while making my post -
But my thinking is....an updated F-14 and F-15 would surly be able to handle the "threats" of tomorrow for at least the next 5 years - and considering that the huge costs the F-22 is showing now....when resources are somewhat limited....currently we are involved in more "smaller scaled engagements" - (though, a big engagement could pop-up tomorrow as well!..and we must be prepared for that...I know).
I just somewhat think we blew it by not upgrading the F-14 - It seems the F-18E/F we replaced it with...(for cost reasons)...has bore out well - with the F-18F proving to be no real replacement for the F-14 -
The bottom line is....We definitely need aircraft that can win the sky's for us - Since we have abandoned the F-14....The Navy definitely needs a new air superiority jet (be it the F-22 or YF-23) The Navy needs one of these jets and we definitely have to bite the bullet and fund it!!
As for the air force.....and upgraded F-15 could still be an option....but at the same time....They don't want the Navy getting a "newer" toy without them getting one as well.
