The Bell Boeing CMV-22 tilt-rotor aircraft is the United States Navy's (USN) chosen successor to the long-running, storied Northrop Grumman C-2 "Greyhound' fixed-wing carrierborne transports. The type utilizes all of the inherent strengths of the existing V-22 Osprey tilt-rotor line with some refinements to suit over-water, carrierborne operations for the USN service. The C-2 family line will, however, continue to operate aboard American carriers in the at-sea, long-range aerial logistics support mission resupply role into 2024 at which point the new fleet of CMV-22 tilt-rotor aircraft is set to take over.
The venerable C-2 Greyhound fleet was introduced during the peak of the Cold War (1947-1991) period, in 1966 with its first-flight had some two years earlier in November of 1964. Despite these dated origins, the series has remained a vital component in USN actions for decades, providing all manner of support over-water and at-sea. Seventeen C-2A models were procured by the USN followed by 39 of the newer C-2A(R) types. All C-2A models have since been retired by the service while the C-2A(R) series remains active as of this writing (April 2019). The USN is the sole operator of this Grumman / Northrop Grumman product.
Its successor, the CMV-22B, is nothing more than a navalized variant of the all-modern, and proven, Bell Boeing V-22 "Osprey" tilt-rotor aircraft line. The design is neither helicopter nor fixed-wing aircraft as it can accomplish both vertical and horizontal flight by way of maneuvering its tilting engine nacelles. This gives the design unparalleled capabilities in reaching those "hard-to-reach" areas through pinpoint landings or stable hovering actions. Each engine, Rolls-Royce turboshafts built by Allison, drive large-diameter, three-bladed main rotors which power the V-22's impressive capabilities.
The Navy's B-model is based in the earlier MV-22B, which was developed to a USMC requirement to fulfill an assault transport role for ground troopers. This model introduced a shipborne operating functionality while also retaining cargo-hauling capabilities. The service has used this mark to replace an aging stock of Boeing CH-46E and Sikorsky CH-53D helicopters since introduction. In USN service, the modified CMV-22B is designated specifically for the Carrier Onboard Delivery (COD) role and improves upon the existing framework by introducing improved communications equipment as well as increased operational ranges - both qualities vital to carrierborne aircraft.
