V-22 (Tilt/Rotor ACFT) Osprey

The V-22 (Tilt/Rotor Aircraft) Osprey Modification Program is managed by the Department of the Navy (DON) with support from the United States Air Force (USAF), and is designed to enhance the operational capabilities, safety, and readiness of the V-22 fleet. The program supports the amphibious and vertical assault needs of the Marine Corps (MV-22), the Carrier Onboard Delivery (COD) mission for the Navy (CMV-22), and special operations for the USAF and USSOCOM (CV-22). The FY26 budget line item funds modifications for MV-22s and CMV-22s, focusing on improvements in safety, reliability, maintainability, and mission capability. Key objectives include accelerating safety initiatives such as the Osprey Drive System Safety and Health Information (ODSSHI) and the Proprotor Gearbox (PRGB) Triple Melt upgrade, as well as implementing readiness and configuration enhancements.

MV-22 Correction of Deficiencies (OSIP 022-01) targets documented safety, maintainability, and system deficiencies across the fleet. This includes avionics upgrades to improve display reliability and resolve communication security and obsolescence issues, as well as cockpit enhancements such as the installation of crash-survivable Cockpit Voice Recorders (CVR), Iridium Antennas for improved communication, and quick-disconnect Cockpit Intercommunications System (ICS) harnesses for increased mission availability. These modifications are implemented via field retrofit and are designed to address both immediate and long-term fleet needs. Procurement and installation schedules reflect aircraft availability and the criticality of the upgrades.

MV-22 Readiness (OSIP 028-12) focuses on correcting factors that degrade aircraft readiness, increase cost per flight hour, and contribute to obsolescence. The program funds upgrades to the power transmission and control systems, cockpit safety improvements, and structural changes to enhance survivability and maintainability. Notable engineering changes include upgrades to the Aircraft Bus Tie Circuit, Auxiliary Power Unit (APU) contactors, Conversion Area Harness (CAH), Drive Link/Proprotor Hub Spring, and Engine Thermo-Couple Wire Harness.

The program also accelerates the ODSSHI initiative, which uses high-frequency accelerometers to monitor gearbox health, and begins procurement of advanced gear diagnostics and leading-edge angle upgrades to further improve reliability and reduce maintenance requirements.

MV-22 Common Configuration (OSIP 011-17) is structured around block upgrades to ensure fleet-wide standardization and alignment with the Commandant of the Marine Corps Force Design 2030 (FD2030) objectives. The program aims to optimize inventory management and capitalize on aircraft downtime by implementing block upgrades that improve readiness, achieve common configuration, and reduce life cycle costs. FY26 funding supports the start of Block 25 and Block 30 modifications, including upgrades to environmental control systems, weather radar, crash position indicators, and cockpit displays. The removal of obsolete systems is also planned to streamline aircraft capabilities.

MV-22 Avionics Improvements (OSIP 009-19) addresses safety of flight, maintenance, and obsolescence issues within the avionics systems. The program supports upgrades to the Advanced Multifunction Display (AMFD), Mission Computer, Traffic Collision Avoidance System (TCAS), and Integrated Aircraft Survivability Equipment (IASE). Additional efforts include the implementation of Platform Data Services (PDS), Vibration Structural Life & Engine Diagnostic (VSLED), Fuel Management Unit (FMU), Drive System Interface Unit (DSIU), and the Common Electronic Standby Indicator (CESI). These enhancements are designed to improve navigation, communication, survivability, and maintainability, while ensuring compliance with Federal Aviation Administration and International Civil Aviation Organization standards.

CMV-22 Improvements (OSIP 005-20) are tailored to support the Navy's COD mission and enhance interoperability within Carrier Strike Groups and Expeditionary Strike Groups. Key objectives include the integration of Link-16 and secure Military Satellite (MILSAT) communications via the Mobile User Objective System (MUOS), compliance with Beyond Line of Sight (BLOS) Air Traffic Control requirements, and upgrades to terrain awareness and warning systems. The program also funds reliability improvements to the Coanda Valve, PRGB Input Quill/Clutch, Conversion Area Harness, and APU contactors, as well as upgrades to cockpit displays, infrared countermeasures, and cargo handling systems. Safety initiatives such as ODSSHI and PRGB Triple Melt are accelerated to address critical drivetrain and gearbox risks.
