Upgrades to the Osprey's nacelle and pylon assemblies aim to bolster the aircraft's reliability and sustain its demanding operational tempo.Ridley Park TodayThe Bell Boeing Joint Program Office has been awarded a $157 million contract by the U.S. Department of Defense to deliver nacelle and pylon upgrades for the Navy's MV-22 and CMV-22 Osprey fleets. The work will be completed by December 2028 across facilities in Amarillo and Fort Worth, Texas, and Ridley Park, Pennsylvania.
Why it matters
The Osprey's nacelles and pylons are among the most maintenance-intensive and operationally critical components of the aircraft. Upgrading these systems is crucial for extending the platform's service life and reducing mechanical issues that have drawn congressional and public scrutiny in recent years. The upgrades will help sustain the operational tempo demanded of the Osprey fleet, which is a core element of the Marine Corps' distributed maritime operations concept and the Navy's carrier onboard delivery capabilities.
The details
The $157 million contract covers the delivery of 10 Nacelle Improvement Kits and 3 shipsets of Pylon Support Assemblies. The majority of the work, 84%, will be performed at Bell Boeing's facility in Amarillo, Texas, with an additional 15% in Fort Worth, Texas, and 1% in Ridley Park, Pennsylvania. The nacelle upgrades target the rotating mechanism and drive systems that allow the Osprey to transition between helicopter and turboprop flight modes, while the pylon upgrades focus on the structural interface between the nacelles and the wing.
- The contract was awarded on April 10, 2026.
- Completion of the work is expected by December 2028.
