The V-22 program office is studying the future of the tiltrotor aircraft, weighing both a technology refresh as well as whether it could rip off the wings and nacelles to add decades of additional life to the airframes.
U.S. Marine Corps Col. Brian Taylor, the joint program manager for the aircraft, told an audience at the Modern Day Marine conference in Washington that the U.S. military is the only one flying a tiltrotor because itâs a complicated plane with a complicated drive system.
That said, Osprey operators continue to find âthe mission sets the V-22 are getting into is absolutely unlimitedâ because the plane is so robust and flexible.
The program office is eyeing a V-22 Cockpit Technology Replacement, or VeCToR, upgrade effort that will begin research and development in 2026 and would be fielded from 2032 to 2042. That effort aims to bring more off-the-shelf technology to the screens, keyboards, computers and radars in the cockpit, for example.
The office is also in the early stages of studying a Renewed V-22 Aircraft Modernization Program, or ReVAMP, effort that would consider how to keep the fuselage for decades beyond what would otherwise be the end of the planeâs effective life in the early 2060s.
Research and development for the ReVAMP effort would formally begin in 2036, according to his briefing slides, and installations would take place in 2042 to 2050.
âIf we had to do V-22 all over again, what would that look like? And really focusing on keeping the fuselage, and maybe you replace the wing and the nacelle, maybe you donât,â he said during his presentation.
âSomething weâre learning about the fuselage is that it is actually kind of life-unlimited, that thereâs enough margin in it. And so if we put a new wing and a nacelle on there, weâre probably good for another 40 years,â he added. âSo that is a study thatâs ongoing, but itâs [all about] how you take this platform and make it available to the servicesâ into the 2070s.
Taylor said the effort is in its infancy and that his office is soliciting ideas and input from industry to shape the effort.
Asked if a V-22 fuselage with new wings and drive system would continue carrying out transport missions or take on other work, Taylor said: âI donât know, and thatâs the fun part.â
Taylor added that the office is considering an optionally unmanned version while it looks at how to make the plane more reliable, maintainable, affordable and safe.
The drive system has been at the heart of several challenges for the platform. In February 2023, the program office halted operations for an undisclosed number of planes until their input quill assembly was replaced. This input quill assembly, which attaches the Ospreyâs engine to its proprotor gear box, was causing hard clutch engagements in cases when the assembly was over a certain age.
Taylor said a new input quill assembly prototype that incorporates 15 design changes will be delivered in the next month or so to begin testing.
The proprotor gear box itself may also see changes in the near term, as it has seen reliability issues, including âchipping,â where metal shavings come off during routine operations and can damage the rest of the drive system. Taylor said the Navy is investing in a gear box upgrade for its CMV-22 planes.
Taylor said the idea was that the program office would work with industry to engineer a plan to extend V-22 fuselages for the next chapter of their service lives. That plan would then go to the Marine Corps, Navy and Air Force so they can decide if they want to spend their money on this life-extension plan or if technology is changing such that theyâd rather pursue something entirely new to meet their mission needs.
âIâm a little bit biased; I would love to see the V-22 stay in service for the next 100 years. But if thereâs a better thing that we need to pivot to, then thatâs really kind of up to the services,â Taylor said.
On the VeCToR cockpit effort, Taylor said the program office is struggling to support displays that were developed in the 1980s.
âWe are kind of at the tipping point where we are spending enough on just maintaining what we have, that itâs time to do something different,â he said. âHonestly, it was a keyboard that pushed me over the edge, the astonishing bill to keep the keyboard on the aircraft. Itâs 26 letters, 10 numbers, maybe a couple other buttons, but it seems like thereâs a smarter way to do this stuff.â
As the Marines undertake this effort, Taylor said he also wants to help the plane become more software-centric to allow for faster capability upgrades.
