For the longer term, the USAF and USN are already looking at an all-new missile that could eventually replace the AMRAAM. The Joint Dual Role Air Dominance Missile (JDRADM) would be a single design suitable for air-to-air and air-to-ground missions. Intended for use on the F/A-22 Raptor, F-35 Joint Strike fighter, legacy fighters, and unmanned combat air vehicles (UCAV), it is expected to offer enhanced propulsion, agility, and lethality, allowing engagements at longer stand-off ranges. The project is still at a very early stage. Studies of potential capabilities and platform integration have already begun, and work is underway on the development analysis process.

This sounds like what I was talking about in the MULTI-ROLE METEOR thread.http://forum.keypublishing.co.uk/showthread.php?t=29303
