Hansundfranz, it's probably a good idea to have a radar in the jet, but with today's datalink technology, having an AWACS around probably makes it nearly redundant. If you can tell where you are by GPS and the AWACS knows where it is the same way, then the AWACS can datalink you his radar data and the software can compensate for the different positions. Now you have a virtual radar that doesn't disclose your position. Just let the software feed position data to the AMRAAMs and watch the enemy jets start fallin'...
Another possibility for the future is space based radar. Give a pilot the same data in the same manner as described for the AWACS above and now he has a very long range radar system that would be VERY difficult to shoot down!
Like I said before, it's probably a good idea to keep a radar on the jet, but if the datalink technology could be made reliable enough, losing the onboard radar wouldn't be that bad an idea as a way to save weight and space for more avionics!
