The Osprey Goes to War
By Richard Whittle
SNIP
"I don't think it's going to be any more vulnerable than the 46 or the
53," Glueck said. A CH-46 can "usually come into a zone a little bit
quicker than the 53s. The V-22 is kind of in between the two."

Maybe no more vulnerable to being shot at.. but the effect of being hit?


The V-22 will have fighter or helicopter gunship escorts when going
into zones where there's a known threat, Glueck said, and the Marines
have mounted a 7.62-caliber M240G machine gun on the rear ramp. The
Osprey also has chaff dispensers, infrared suppressors, and electronic
defenses.

If it has a cobra escort.. Well.. It loses it's altitude/ speed
advantage over alternative modern helicopters..

Can the V-22 fly "like a plane" with the ramp down? At what penalty?

I know the CH47 has a MG on the rear ramp, but that's a wider, bigger
ramp.. How much of an obstruction is it for troops trying to get out in
a hot LZ?
