Platform for Future AWACS.

What aircraft would make the best conversion to an AWACS plat form in the future.

For the USA.

I am thinking the 7E7 Dreamliner, its small but will be very efficient long range platform, with maybe enven higher endurance then most of its competitors.

For India, maybe the transport aircraft it is producing with Russia

For UK, maybe one of the Airbus Family of aircraft (i think the A380 would be over kill but they might be able to provide CAS by parachuting Stryders where needed from an A380)..

France ?

your thoughts please.
