Bell Boeing CMV-22B Osprey: Mach 0.6, 6,000 lb Cargo & Carrier-Based Tiltrotor COD Specs
1. Overview
The Bell Boeing CMV-22B Osprey is a tiltrotor aircraft developed for the United States Navy as the replacement for the C-2A Greyhound carrier onboard delivery (COD) aircraft. As a variant of the V-22 Osprey family, the CMV-22B combines the vertical takeoff and landing capabilities of a helicopter with the speed and range of a fixed-wing aircraft, enabling it to deliver critical cargo, mail, and personnel to carriers at sea. The CMV-22B entered service in 2020 and has since become an essential part of carrier logistics.
The CMV-22B was developed under the Navy's requirement for a more capable COD aircraft that could carry the F-35's F135 engine—a load that would not fit in the C-2A. The Osprey's unique tiltrotor configuration allows it to carry oversized cargo internally while maintaining the speed and range needed to support carriers operating far from shore. Unlike the C-2, which required a catapult launch and arrested landing, the CMV-22B can take off and land vertically, operating from carriers without the need for catapults or arresting gear.
The aircraft's designation "CMV-22B" indicates its mission: Carrier, Multi-mission, Vertical lift. The CMV-22B differs from the Marine Corps MV-22 and Air Force CV-22 in several ways, including extended-range fuel tanks, a public address system for deck operations, and improved high-frequency radios for long-range communications. With 48 aircraft planned for the Navy, the CMV-22B ensures that carriers can receive the supplies they need, when they need them.

3. Velocity Engineering
The CMV-22B Osprey's tiltrotor design is the key to its unique capabilities. Two 38-foot diameter, three-bladed rotors mounted at the wingtips rotate 97 degrees from vertical (helicopter mode) to horizontal (airplane mode), transitioning the aircraft through the most demanding flight regime in aviation. The conversion takes approximately 12 seconds and is fully automated, with flight control computers managing the complex aerodynamics.
Power comes from two Rolls-Royce AE 1107C Liberty turboshafts, each producing 6,150 shaft horsepower—making them among the most powerful engines ever fitted to a rotorcraft. The engines are cross-shafted, allowing either engine to power both rotors in the event of a failure. This cross-shafting runs through the wing's leading edge and is rated for 7,500 hp continuous, a remarkable piece of mechanical engineering that ensures the aircraft can continue its mission even with an engine failure.
In helicopter mode, the CMV-22B achieves hover performance comparable to the CH-46 it replaces, with a vertical rate of climb of 2,300 ft/min and the ability to hover out of ground effect at 10,000 ft on a hot day. Rotor downwash velocity is approximately 80 knots—significantly higher than conventional helicopters—requiring special procedures for deck operations. The aircraft's folding rotor system allows compact storage on crowded carrier flight decks, reducing the footprint by 50%.
In airplane mode, the CMV-22B's wing provides efficient high-subsonic lift, with a cruise speed of 280 knots—twice that of conventional helicopters. The CMV-22B features extended-range fuel tanks in the wings, increasing range by 200 nautical miles compared to the MV-22. This additional range ensures the aircraft can reach carriers operating at extended distances from shore, a critical requirement for the COD mission.
4. Systems & Technology
Cargo Handling System: The CMV-22B is optimized for COD operations. The cabin features a powered ramp, roller system, and winch for rapid loading and unloading of cargo pallets. The aircraft can carry a 463L master pallet, allowing it to interface with the Navy's existing logistics system. The cabin accommodates the F-35's F135 engine in a protective cradle—a load that would not fit in the C-2A Greyhound and was a key requirement for the CMV-22B.
Extended Range Fuel System: The CMV-22B features additional fuel tanks in the wings, increasing internal fuel capacity by 4,000 pounds. This extended range ensures the aircraft can reach carriers operating at 1,150 nautical miles from shore while carrying 6,000 pounds of cargo. The fuel system includes provisions for aerial refueling, though the CMV-22B is typically refueled on the ground.
Carrier Suitability: The CMV-22B is designed for safe operation from aircraft carriers. The aircraft includes a public address system for communicating with deck crews during spotting and movement. Enhanced lighting improves visibility during night operations. The landing gear is strengthened for the high sink rates typical of carrier vertrep (vertical replenishment) operations, and the rotor brake stops the rotors quickly after landing.
Communications Suite: The CMV-22B carries enhanced communications equipment for long-range COD operations. High-frequency radios provide beyond-line-of-sight communications, while satellite communications ensure connectivity with the carrier and shore stations. The aircraft can receive secure data links for mission updates and weather information.
Avionics: The glass cockpit features four 6x8-inch multifunction displays, with moving map, FLIR, and radar imagery. The digital map system integrates with GPS/INS for precise navigation, essential for locating carriers at sea. The aircraft includes a Terrain Awareness Warning System (TAWS) and Traffic Collision Avoidance System (TCAS) for safety in crowded airspace.
5. Operational Role
The CMV-22B Osprey performs the critical carrier onboard delivery mission for the US Navy:
Critical Parts Delivery: The CMV-22B's most important mission is delivering high-priority parts, including F-35 engines, to carriers at sea. A broken F-35 engine can ground multiple aircraft; the CMV-22B can deliver a replacement engine within hours, keeping the air wing operational. This capability was a key requirement for the program.
Mail and Personnel Transport: The CMV-22B carries mail, supplies, and personnel to and from carriers. The aircraft's speed and range ensure that sailors receive mail and supplies faster than with the C-2A. The cabin accommodates up to 27 passengers in airline-style seating, or 20 passengers with cargo pallets.
Vertical Replenishment: The CMV-22B can transfer cargo between ships using its vertical takeoff and landing capability. The aircraft can lift 20,000 pounds externally, moving pallets of ammunition, food, and supplies between supply ships and combatants.
Medical Evacuation: The CMV-22B can be configured for medical evacuation, with space for litters and medical equipment. The aircraft's speed and range enable rapid transport of casualties to shore-based medical facilities.
The US Navy plans to acquire 48 CMV-22Bs, with initial squadrons at NAS North Island, California, and NAS Norfolk, Virginia. The aircraft has already supported carrier deployments in the Pacific and Middle East, proving its value for COD operations. The CMV-22B replaces the C-2A Greyhound, which had served since the 1960s.
6. Performance Analysis
CMV-22B vs C-2A Greyhound: The C-2A Greyhound was a carrier-based turboprop that served as the Navy's COD aircraft for 50+ years. The C-2A could carry 10,000 lb payload but required a catapult launch and arrested landing. The CMV-22B operates vertically, freeing up catapults for combat aircraft. The CMV-22B is faster (280 knots vs 250 knots) and has longer range (1,300 nm vs 1,200 nm). The CMV-22B can carry the F-35 engine; the C-2A could not. The C-2A is being retired as CMV-22Bs enter service.
CMV-22B vs MV-22 Osprey: The CMV-22B shares 95% commonality with the Marine Corps MV-22, but with key differences. The CMV-22B has extended-range fuel tanks (4,000 lb additional), a public address system for deck operations, and enhanced HF radios. The CMV-22B's mission is logistics, while the MV-22 is optimized for assault support. The CMV-22B sacrifices some cargo capacity for range, ensuring it can reach distant carriers.
CMV-22B vs CH-53K King Stallion: The CH-53K is a heavy-lift helicopter with higher payload (36,000 lb vs 20,000 lb) but slower speed (150 knots vs 280 knots). The CH-53K is optimized for ship-to-shore heavy lift; the CMV-22B is optimized for long-range logistics. The two aircraft complement each other: CH-53Ks move heavy equipment ashore; CMV-22Bs move critical parts and personnel between shore and carrier.
7. Carrier Logistics Revolution
The Bell Boeing CMV-22B Osprey represents a revolution in carrier logistics. For 50 years, the C-2A Greyhound did the job well, but it had limitations: it required a catapult, couldn't carry the F-35 engine, and was limited in range. The CMV-22B overcomes all these limitations, providing the fleet with a logistics aircraft that can go where needed, carry what's needed, and get there faster than ever before.
The CMV-22B's ability to carry the F-35 engine is perhaps its most significant capability. The F-35 is the most advanced fighter in the world, but its engine is complex and occasionally needs replacement. Before the CMV-22B, a broken engine meant the aircraft was out of action until a ship could return to port or a C-2A could deliver a replacement—a process that could take days. Now, a replacement engine can be delivered within hours, keeping the air wing at full strength.
The CMV-22B's impact extends beyond engine transport. It delivers mail, parts, and personnel faster than ever before, improving quality of life for sailors and maintaining combat readiness. Its vertical takeoff and landing capability frees up catapults for combat aircraft, increasing the carrier's striking power. And its range ensures that carriers can operate at greater distances from shore, keeping them safer from land-based threats.
For the Navy, the CMV-22B is more than a replacement for the C-2A—it's a force multiplier. It ensures that the carrier strike group has the logistics support it needs to stay on station, ready to fight. For the sailors who fly it and the deck crews who handle it, the CMV-22B is a welcome addition to the fleet, bringing with it the promise of faster, more reliable logistics. The Osprey has found a new home at sea, and the Navy is better for it.
