Media,
It does not matter how efficient the machine is on fuel...if it cannot accomplish the mission....it is the wrong aircraft for the job. The key point is the loss of mission by the Air Force and the overburdening of the Army as a result. Just why would a former Special Ops Squadron mission be going to a helicopter and one from another service of all things?
Throw in the consideration of Spec Ops missions in Afghanistan and other high altitude locations....just how is the Osprey supposed to do the work?
The MH-53M cannot...two engines...but the three engine version is the cats meow...or the Chinook with the right avionics fit.
