The Osprey, which takes off and lands like a helicopter but flies like a plane, was designed to replace the Corps' aging and less-capable helicopter fleet.
The military, which has ordered 360 of the aircraft, said the 10 deployed to Iraq are doing what they are supposed to do -- carrying troops faster, farther and safer than the copters can.
In December, commanders gave the planes a more risky mission called "aero-scout" in which a group of V-22s flies into a relatively unsecured location and drops off Marines for a search mission.
The Osprey seems to have become a favorite of commanders who need to get to places quickly, including Gen. David Petraeus, the top U.S. military commander in Iraq. Petraeus used one to fly around the country on Christmas Day to visit troops.
"Gen. Petraeus flew in the jump seat and was very impressed by the aircraft's capabilities," according to Col. Steve Boylan, a spokesman for the general.
"The rate of climb is exceptional, and it can fly about twice as fast as a Black Hawk [helicopter], without needing to refuel as frequently," Boylan said. "Beyond that, its automatic-hover capability for use in landing in very dusty conditions, even at night, is tremendous."
Petraeus chose the Osprey for that mission because it was the only aircraft in the inventory that could fly around the country without refueling and not rely on runways, Boylan said.
Another indicator that helicopters are going to yield the scene to other flying apparatuses, like ospreys and drones.
