They're continuing to upgrade it. Why don't we buy some of these?
400kts, same weapons (including development for GBU-38 and GBU-49; bet they could even integrate PWIV and DMS if we asked nicely), same ground station, same instrumentation, same radar, adds the JSF EOTS, similar endurance.
We could have our existing REAPER (thanks iRaven!) aircrew flying them on missions pretty much immediately, I imagine.
