They want slow speed manouverability abilities and fast transit speed.
So why they're retiring Tomcat (and Aardvark) if they want those?
Well, at least they aren't retiring Bone.

the Tornado was already retired, right?
Tomcats are just bloody flying missile launchers, no more. Also, Tomcats are not much more youthful than Aardy's.
You can only put so many hours into airframes before you have to throw them away, just out of sheer age related risk. That's why all the B-52's flying today are National Guard etc, all airframes that were only ever used on Sundays by little old ladys going on Bombing runs to the supermarket.
Otherwise you'd still see masses of the old dears flying. As far as getting ordinance up, nuthin beats an ole B-52, just as long as you have air superiority and you've wiped out the long range Air ro Air sites..:)
As far as the actual wing warping aircraft, they aren't really a direct comparison to the slingwings as mentioned. Same reasons and principles, waaaay waaay different tech.
I’ve never heard of “sling-wings” – “swing wings” or “variable sweep wings” are more common.
As far as this morphing wing stuff goes – I had heard that the superhornet and even the 7E7 were going to incorporate the technology, but it has taken much to long to develop and it’s going to have to wait for the next generation.

Yep, it's called swing-wing most commonly.
One of the beiggest things which affects to maximum speed is angle of leading edge
Good example is that if you look Tomcat flying at high speed it looks very much like arrow.

I think that they are talking about physically distorting the shape of the airfoil, not just changing the wing's presentation angle to the airstream. Think of the wing with a balloon inside, or some such thing..
The (potential) benefits could be great, if they can find the right smart materials to make it work such that itwould also naturally return to a "failsafe lift mode" if power to the control systems were lost.

[B]the correct term is "Sling Wing" aircraft...the Tornado was already retired, right? [/B][/QUOTE]
Actually, the correct term is "variable geometry wing." The colloquialism isn't "sling wing," it's "swing wing."
BTW, I managed to tour the CG-51 today. It's an amazing ship and a shame they will be retiring it in 2006 as part of the move to get rid of all non-VLS surface warships.
The term Variable Geometry is the correct usage here. It refers to the variable geometry wing meaning the damn things move.
And it is considered an Aircraft with variable geometry wing configuration, thats straight from General Dynamics and Grumman (maker of the F14).
[B]No. The term "variable geometry" refers to the wings only. [/B][/QUOTE]
Yep
And BTW, JSF's maxmimum speed is much smaller than what F-22 have because leading edge's angle is much closer to 90 degree. (or saying otherway, it's optimized for slower speeds)

That isn't why the JSF has a lower maximum speed. It's an end
result (not a cause) of the fact it's mission doesn't require it
to go as fast.
