I am a bit skeptical of the ac, but let's see what it does.

AHS

"The MV-22 Osprey is a very capable medium-lift military transport
aircraft the Marine Corps has needed for a long time. It is twice as fast,
can carry three times as much, and goes six times farther than the CH-46E,
the aircraft it is replacing."

Twice as fast.. close enough
three times as much? 25 men vs 32.. Nope. Cargo? loaded - empty = V-22 @
~6,000 pounds, CH-46 ~ 2000 pounds.. So in the cargo role, yes.. In the
troop landing role, (@ max take off - 8763 lb (CH-46) vs 27360 lb V-22 ..
~3 times..
6 times farther... Combat radius 370 nm vs 184.. Call it twice the
distance... ferry range.. 2417 vs 420 nm ~ 6 times..

Very selective choice of statistics...

Precision high-performance components mean close tolerances - and fine
Arabic sand is the enemy of close tolerance bearings and fittings.

Marines hate uncertainty more than they fear failure. It is time for the
V-22 to step up.
