As compared to the MV-22B, the Navy variant has extended operational range, a beyond line-of-sight HF radio, improved fuel dump capability, a public address system for passengers, and an improved lighting system for cargo loading. The CMV-22B will be capable of transporting up to 6,000 pounds of cargo/personnel to a 1,150 NM range.
The CMV-22B is expected to field with Initial Operational Capability (IOC) and deploy for the first time (projected) in 2021.
Weight: Max. gross, vertical take-off: 52,600 lbs. Short take-off 57,000 lbs (testing in progress to increase)
Airspeed: Cruise: 269 knots
Ceiling: 25,000 feet (7,620 meters).
Range: 1,165 nautical miles
Crew: 4 – pilot, copilot, crew chief, second aircrewman; 23 passengers
Not to minimize the work, but it does sound quite similar to the MV. Should cut down on surprises. I don't think the main cabin has pax air- at least in the MV, so ceiling may be seldom reached.
