U.S. Marine Corps MV-22s in Iraq in the last couple of weeks have begun flying aerial scout missions in support of raids in Al Anbar province. That’s according to the Marine commandant, Gen. James Conway, who met with reporters at the Pentagon yesterday. While raids have become less frequent, he said, the Ospreys are demonstrating one of their advantages. "The 22 is very quiet," Conway said. "It's an added advantage when it comes to getting troops on the ground without hearing a helicopter coming from a couple miles out."
That kinda surprises me because I've been on the golf course here in Yuma when one or two have flown over. The first time I was curious as to what it was, not having heard one before. Second and subsuquent times I knew what the noise was and was excited to see one in flight. I would estimate the noise level to be less than a UH-1 but more than a TH-57. You definitely know something is in the neighborhood. My experience was with birds in F/W mode and not hovering so that could make the difference, I guess.
