Operators of the C-17 Globemaster III have been reaching out to Boeing about possibly restarting the product line, and the company has been “encouraged” by these engagements. Separately, Congress recently directed the U.S. Air Force to prepare a formal briefing on the feasibility of acquiring new Globemaster IIIs. The Air Force’s C-17 fleet is critical for U.S. power projection globally. At the same time, a succession of crises in recent years has put serious strain on these aircraft, and questions have already been raised about the viability of the current plan to keep them flying through 2075.

The House Committee on Armed Services added the requirement for the C-17 production restart briefing to a report accompanying the latest draft of the annual defense policy bill, or National Defense Authorization Act (NDAA), last week. The Air Force took delivery of its last Globemaster III in 2013, and has some 222 of these airlifters in service today. The air arms of Australia, Canada, India, Kuwait, Qatar, the United Arab Emirates, and the United Kingdom also have smaller fleets of these airlifters. Three more of these aircraft are operated under the Strategic Airlift Capability (SAC) initiative, a multi-national arrangement with several European members, as well as the United States. Boeing shuttered the C-17 line entirely in 2015.

“The committee recognizes that the existing C-17 fleet continues to bear significant operational demands supporting combatant commander requirements, humanitarian assistance missions, and global mobility operations,” the provision in the House Committee on Armed Services’ report notes. “The committee is concerned that future operational demands may place additional strain on the existing C-17 fleet.”

“Therefore, the committee directs the Secretary of the Air Force to provide a briefing to the House Committee on Armed Services not later than March 1, 2027, assessing the feasibility of restarting the production line for the C-17 aircraft,” it adds.

The committee wants the Air Force’s briefing to at least include the following:

• “An assessment of the technical and industrial feasibility of restarting the C-17 production line, including the status of tooling, supplier base viability, workforce availability, and potential reconstitution costs.”
• “An estimate of the timeline required to reestablish production and deliver the first newly produced aircraft.”
• “A cost estimate for restarting the production line and procuring additional aircraft, including options for limited procurement and multi-year procurement.”
• “An evaluation of alternative approaches to increasing strategic airlift capacity, including service life extension programs, modernization of existing aircraft, procurement of commercial derivative cargo aircraft, and expansion of the Civil Reserve Air Fleet.”
• “An assessment of potential international partner interest in participating in or contributing to a restarted production line.”

TWZ subsequently reached out to Boeing to ask about the company’s current position on rebooting C-17 production.

“Our goal is to help our customers be successful, and we work with them to develop innovative solutions to meet their mission needs, including development and production partnerships,” a Boeing spokesperson told us this week. “We are proud of our continued support for the unique, mission-proven capabilities that the C-17 Globemaster III delivers to the U.S. Air Force and eight allied nation partners.”

At the Paris Air Show last year, Turbo Sjogren, Vice President and General Manager of Boeing Global Services-Government Services, had told Shephard Defense that talks with an unnamed country about a possible C-17 production restart were in their “early infancy.”

“It is a very extraordinary effort to do” and is “reflective of the utility of the aircraft,” he also said at the time, according to Shephard.

Boeing has also now said that it is always willing to work to better understand the requirements and needs of its customers. Any talk about the prospect of restarting C-17 production would also have to be viewed in the broader context of the Air Force’s still-evolving requirements for the Next Generation Air Lift (NGAL) program. The service’s current NGAL plans envision a single aircraft replacing the very different C-17 and C-5 Galaxy fleets, as you can read more about here.

TWZ also reached out to the U.S. Air Force about the recently requested briefing.

It is unclear what it might cost to get the C-17 line restarted and what the unit price of these new-production aircraft would be in the end. There are various factors at play, including whether Boeing retains any relevant tooling, the knowledge base of its current workforce, the state of third-party supply chains, and the availability of physical space to build the airplanes. Back in 2019, the company sold off the facilities in Long Beach, California, where it built the original run of Globemaster IIIs.

More than a decade ago, the RAND Corporation did conduct a detailed, independent analysis that explored options for resuming production of the baseline C-17A, a new C-17B, and a significantly revised “fuel efficient” C-17FE derivative.

The C-17B was “a variant Boeing has proposed that adds centerline landing gear, a tire deflation/inflation system, higher-thrust engines, advanced flaps, and an advanced situational awareness and countermeasures system,” according to RAND’s report. The C-17FE derivative “would have a narrower fuselage, up-rated engines, a double-element flap system, winglets, a longer loading ramp, a shorter cargo door, and a modified horizontal tail.”

RAND said that it could cost between $2.1 and $2.7 billion in 2011 dollars to begin making C-17A models again after a pause, depending on how much tooling Boeing retained. The cost ranges would be $4.6 to $6.4 billion for new production of the improved C-17B version, and $6.2 billion to $7 billion to start building the C-17FE derivative. Billions more would be required to actually procure the aircraft, with unit prices being highly dependent on the total size of the production, as outlined in the table below. If nothing else has changed, these cost projections would still be significantly higher today just due to inflation.

As an aside here, RAND published a similar assessment of the options for restarting production of the F-22 Raptor in 2011. That report factored heavily into a study the Air Force subsequently delivered to Congress on that topic back in 2017, which you can read more about here.

Foreign participation in new production of C-17s could help defray costs, and is one of the points the House Armed Services Committee specifically wants the Air Force to address in its briefing. As TWZ noted last year after Turbo Sjogren made comments at the Paris Air Show, Boeing’s discussions at that point might not have been with the U.S. government. Earlier in 2025, then-Japanese Prime Minister Shigeru Ishiba had expressed interest in buying Globemaster IIIs, raising immediate questions about where those aircraft might come from.

It should be noted here that the U.S. Air Force’s C-17s have received various upgrades over the years, and the service continues to move ahead with other plans to improve their performance and expand their capabilities. This includes the installation of 3D-printed microvanes on the fuselage, which offer a very minor reduction in drag (approximately one percent), but that translates into real reductions in fuel consumption. All Air Force C-17s are expected to have this feature by the end of next year. Communications and data-sharing upgrades have also been a major focus area across all of the Air Force’s airlift and tanker fleets.

Boeing is now under contract for a more extensive upgrade of the flight decks on Air Force C-17s. The company says this will aid in “resolving avionics obsolescence” and integrate new open systems architectures to make it easier to add new and improved capabilities and functionality in the future.

The prospect of a re-engining effort for the Globemaster III fleet has also been raised in the past, but the Air Force downplayed the value of doing so earlier this year.

When it comes to discussions about restarting C-17 production, another key factor is the lack of immediate alternative options. There is really no other aircraft in this class in production now in the United States or anywhere else in the West. Airbus has long positioned its turboprop-powered A400M as sitting in a capability space between Lockheed Martin’s C-130 family and the C-17. Embraer’s KC-390 Millennium design, which is also offered as an aerial refueling tanker, has generally been pitched as a jet-powered competitor to the C-130. China’s Y-20 and Russia’s Il-76 are really the only in-production analogs on any level to the C-17 globally.

The House Armed Services Committee has now also asked the Air Force to speak to the possibility of buying “commercial derivative cargo aircraft” and/or an “expansion of the Civil Reserve Air Fleet,” or CRAF, to help bolster airlift capacity. The CRAF is an arrangement by which the U.S. military can call upon commercial airlines and charter companies to help move cargo and personnel, which you can learn more about here.

A key issue here is that the C-17 is specifically designed for tactical operations right at the tactical edge. This includes the ability to bring combat-ready forces to far-flung locations without the need for an established airfield. Additional commercial alternatives could still be utilized in rear areas to help free up C-17s for more demanding missions and otherwise relieve stress on the Globemaster III fleet.

Questions have been increasingly raised about the survivability of the C-17 itself, especially in the context of a future high-end fight, as the threat ecosystem continues to expand and evolve. The Air Force has made clear that it is working to find new ways to bolster the defensive capabilities of all of its existing airlifters, as well as its tanker fleets, and that this is a key consideration in the evolving NGAL requirements.

TWZ has long been sounding the alarm on the need for more survivable cargo planes and tankers. The Air Force already has decades’ worth of experimental work and studies on concepts for stealthy cargo aircraft and tankers, as well as non-stealthy ones with blended-wing-body (BWB) planforms, under its belt. Over the years, several companies have publicly put forward prospective designs that could be relevant for NGAL, as well.

When any new platform developed under NGAL actually enters service remains to be seen. The stated plan the Air Force has put forward to date would see those new aircraft replacing its C-5s first, with C-17s flying through 2075. By that point, the Globemaster III, as a type, will have been in service for 80 years.

“The C-17 is the most amazing airplane ever made. I have a lot of time in it, so I can say that. We have asked it to do a lot of things, and it’s done more than we ever planned for when we bought that airplane,” Air Force Lt. Gen. Rebecca Sonkiss told TWZ and other outlets at a roundtable on the sidelines of the Air & Space Forces Association’s (AFA) annual Warfare Symposium in February. “It has performed flawlessly, but it’s getting old too.”

Sonkiss is Deputy Commander of Air Mobility Command (AMC). She has been serving as the interim head of the command since her predecessor, Gen. John Lamontagne, became Vice Chief of Staff of the Air Force in January.

“I cannot have a gap in my strategic airlift forces, and we’re working forward on the NGAL to combine the view of the C-5 and the C-17 fleet and figure out what the next strategic airlifter needs to be. That conversation, in my book, can’t happen enough, or can’t happen fast enough,” she added at the roundtable in February. “We have to get after what next looks like, and we can’t wait until we’re shoveling it into the boneyard before we get to that discussion.”

Whether the Air Force’s future airlift plans also include buying new-production C-17s remains to be seen. For its part, Boeing does not appear to have ruled out the possibility just yet.

The U.S. Air Force has confirmed that the VC-25B “Bridge” aircraft is now wearing its new (and controversial) red, white, and blue livery as it undergoes final preparations for its official delivery.

Aviation photographer Travis Ghormley shared the first picture of the modified Boeing 747-8i with its new paint scheme yesterday. It was taken the day before in Waco, Texas. The aircraft had been undergoing modification and flight testing at L3Harris’ facility in Greenville, also in Texas, as part of the conversion into its new role, since at least April, before subsequently moving to Waco to be painted. The jet, gifted to the Trump administration by the government of Qatar last year, is set to serve as an interim Air Force One aircraft ahead of the much-delayed arrival of two fully outfitted VC-25Bs from Boeing.

“The VC-25B Bridge aircraft has been painted and is going through final modifications,” an Air Force spokesperson told TWZ today when asked for more information about the aircraft’s current status. “I don’t have any additional details I can provide on delivery dates at this time.”

A press release the Air Force put out on May 1 said that the “VC-25B Bridge aircraft has officially completed modification and flight testing” and was “being painted.” We have confirmed that the completed modifications referred to here were on the contractor side, but the U.S. government still has additional modifications to make to the jet.

Ghormley’s picture does clearly show the jet wearing the same red, white, and blue scheme that has already been appearing on various Air Force and other U.S. government VVIP jets. The livery also includes a large American flag, depicted blowing in the wind, painted on both sides of the tail and “UNITED STATES OF AMERICA” written on both sides of the fuselage. The paint job is virtually identical to what President Donald Trump had previously chosen for the future VC-25B Air Force Ones during his first term. President Joe Biden had previously reversed that decision, bringing back plans to paint the VC-25Bs in the iconic scheme that dates back to President John F. Kennedy’s administration.

The Bridge aircraft’s current location is also unclear. Video posted on social media yesterday, seen below, purported to be of the jet departing for its new home at Andrews Air Force Base just outside of Washington, D.C. This is where the two current VC-25A Air Force One jets, as well as a host of other Air Force VVIP aircraft, are based.

Full blown operation to get this thing out without us seeing. Fueled, loaded crew, and preflighted in the hangar. Flipped CRANE01 to face me at the south end and beam me with landing lights. Entire airport blacked out, crew and grounds crew all wearing NOD’s.

Online flight tracking data does show that another U.S. military Boeing 747-8i flew from Waco, Texas, to Andrews on June 7, using the callsign Crane 01. However, this callsign has been associated with an ex-Lufthansa 747 the Air Force has also acquired for use as a trainer in support of future Air Force One operations. This aircraft, which may now carry the serial number 25-3200, has been tracked multiple times flying between facilities in Texas and Andrews in recent months. There does not appear to be tracking data for the VC-25B Bridge jet, which may also now have the serial number 25-3300, but it could have made the trip without broadcasting on ADS-B.

Past reports have indicated that the Bridge aircraft could make its public debut on July 4, which this year is also wrapped up in additional celebrations of the 250th anniversary of the founding of the United States. President Trump’s birthday (June 14) is also this weekend.

Otherwise, TWZ has previously laid out significant questions about the general feasibility of actually using the VC-25B Bridge aircraft in the Air Force One role, given the kinds of modifications that should be required for this demanding mission. Potential operational security concerns have been raised about using the gifted jet as a presidential aircraft, as well.

“L3Harris, known for its executive communications systems and services, was selected to undertake a complex modification of the bridge aircraft. L3Harris not only delivers secure, reliable and resilient communications for VC-25A and the executive airlift fleet but has extensive experience with self-protection and customization of VIP aircraft,” the Air Force wrote in the May 1 press release. “The accelerated timeline was further made possible by a mission-focused partnership with Boeing, who provided the necessary engineering data to support the required structural modifications.”

“Additionally, elite specialists from multiple government agencies developed advanced protocols to detect and-if necessary-neutralize potential technical hazards on previously owned aircraft,” it added. “Their rigorous approach on the Bridge aircraft has literally ‘written the book’ and set the benchmark for integrating used airframes into the secure military inventory.”

“Safety and security were at the forefront of this program. We deliberately minimized interior aesthetic modifications to focus on modifications for safety, security and mission execution. We assessed which requirements were necessary for an interim capability. We had greater flexibility in developing our mission requirements,” the Air Force also told TWZ directly at that time. “After safety and security, we focused on the mission communications systems.”

“We have made deliberate decisions such as the reduction of the number of airstairs, less chiller space, and exclusion of the Golden Eagle mission [to fly the remains of former presidents] to minimize structural modifications, while prioritizing modifications focused on safety, security and secure communications,” the service added.

Getting a new Air Force One aircraft of some kind into service on an accelerated timetable has long appeared to be a major goal for President Trump. The fully-equipped VC-25Bs from Boeing are years behind schedule. Last year, the Air Force announced that there had been some improvement on that front, but that it still did not expect to have the first of the two jets in hand until mid-2028, which would be just months before Trump is set to leave office.

What we do know for sure is that the VC-25B Bridge aircraft is now wearing Trump’s preferred red, white, and blue paint scheme ahead of its official rollout later this summer.
