V-22 sorted? Not hardly....it is still in use. One small example of the problems is an engine change aboard ship. It has to be done on the flight deck and not in the hangar deck due to height problems in the configuration required to change the engine.
Check the dimensions of the cabin and ramp entrance when you consider it as a COD aircraft. Also consider the payload as compared to current COD aircraft.
Bottom line....consider it's cost vice an airplane of any description that would fill these roles. The E-2 does the AEW role admirably (probably a bad use of word considering some of the Admirals about today). At approximately 51 Million USD per copy.....it beats the hell out of the V22. The E-2D is coming off the line and will be state of the art when it comes into service.
Rotorheads forum has an ongoing discussion of the V-22 in this thread:
