From Flightglobal:
Operating from Sikorsky’s flight-test centre in West Palm Beach, Florida, the first engineering development model (EDM) recently achieved 120kt, just 21kt shy of its advertised speed of 141kt.
What happened to the cruise speed of 170 Knots? For $25 Billion+ the US should be getting something faster that an ASTAR or 407. So the V-22 is twice as fast.
