The Boeing C-17 Globemaster III has been out of production since 2015, but the US military may now be considering something that seemed impossible just a few years ago: bringing the aircraft back. The House Armed Services Committee has directed the US Air Force to study whether the dormant production capability can be restored and report its findings to Congress. The C-17 remains one of the world's most capable strategic airlifters, combining a 77.5-tonne payload with the ability to operate from relatively short and austere runways.
That flexibility is what has kept the C-17 relevant decades after its introduction. The aircraft can transport tanks, helicopters, troops and oversized equipment while operating from locations that are inaccessible to many other strategic transports. Its ability to land on short or unprepared runways, reverse using its own thrust reversers and operate with a relatively small crew makes it particularly valuable for military logistics. The US Air Force is already investing in upgrades to keep the aging fleet operational, including aerodynamic improvements and cockpit modernisation.
The problem is that there is currently no Western aircraft in production that directly replaces the C-17. The Airbus A400M and Embraer KC-390 occupy smaller categories, while China's Y-20 and Russia's Il-76 are not realistic alternatives for existing Western operators. The US plans to keep its C-17 fleet flying for decades, potentially into the 2070s, while its next-generation airlift programme is not expected to become operational until around 2040. That creates a significant capability gap if the existing fleet begins to decline faster than its successor arrives.
Restarting production, however, would be far more complicated than simply reopening a factory. Boeing sold the original Long Beach facility, while much of the tooling, workforce and supplier network have moved on. Rebuilding the industrial base could cost billions before the first aircraft is even produced. India and other C-17 operators could potentially provide additional demand, but the US Air Force must determine whether restarting production makes more sense than extending existing aircraft or investing directly in a new airlifter. The Air Force's assessment is expected to address these options before March 2027.
Boeing hasn't built a new C-17 Globemaster III aircraft since 2015.
The factory that made them was sold off years ago, and the supply chain that supported it
has moved on to other work.
That should have been the end of the story.
But this past June, the U.S. House Armed Services Committee ordered the Air Force to formally
study whether that dead production line could be brought back, with a hard deadline to report
back.
So in today's video, we're taking a closer look at the C-17 Globemaster III, what it
can carry, where it can land, why nothing built since has been able to replace it, and
what it would actually take to bring production back.
Let's dive in.
Widely considered the most flexible cargo aircraft to enter an airlift force, the C-17
Globemaster III is a four-engine strategic airlifter originally developed by McDonnell
Douglas and now built by Boeing.
It entered the U.S. Air Force service in 1995.
A total of 279 were built before production ended in 2015, going to nine operators, and
roughly 275 remain in service worldwide today.
The C-17 is powered by four Pratt & Whitney F117 turbofans, the military version of the
engine used on the Boeing 757, giving it a cruise speed of around 830 kilometers per
hour and a maximum takeoff weight of about 265 tons.
Maximum payload is 77.5 tons, which covers a main battle tank, three attack helicopters,
or well over 150 troops.
With a full load, it can fly roughly 4,400 kilometers unrefueled and considerably further
when empty or aerially refueled.
It is also unusually easy to operate for its size, since a crew of three can fly it, where
older heavy lifters needed five or more.
The cargo hold itself is large enough to load vehicles too abreast, and the aircraft can
using thrust reversers, a feature almost no other jet transport has, letting it back out
of a parking spot with no ground support at all.
The specification that matters most is not the payload, but where the payload can be
put down.
The C-17 can land on an unpaved strip of 900 meters or less, then reverse itself back out
under its own power.
That combination is what lets it deliver a tank to a dirt airfield rather than to a distant
hub, and it is why it can operate into places like Kargil, sitting nearly 3,000 meters up
in the Himalayas.
Everything from micronuclear reactors to grounded F-35s has been flown inside one.
The famous Kabul evacuation flight that carried 823 people out on a single aircraft was a
C-17 as well.
The Air Force is also steadily modernizing the type rather than letting it age in place,
fitting three D-printed drag-reducing micro vanes to the fuselage across the whole fleet
and contracting Boeing for a flight deck overhaul aimed at fixing avionics obsolescence and
opening the door to future upgrades.
The U.S. Air Force holds the overwhelming majority with around 222 aircraft and took
delivery of its last one in 2013, meaning the newest airframe in American service is
already well over a decade old.
Outside the U.S., the operators are the United Kingdom with eight, Australia, Canada, India,
Kuwait, Qatar, and the UAE, plus three aircraft flown collectively under NATO's Strategic
Airlift Capability Arrangement out of Hungary, whose members now include Finland and Sweden.
India is the second-largest operator, with 11, based at Hinden Air Force Station.
And Indian defense outlets report the fleet has maintained near-total availability rates
since it entered service.
There is no aircraft in this class in production anywhere in the West.
Airbus has always positioned the turboprop A400M as sitting between the C-130 and the
C-17 rather than replacing either.
And Embraer's KC-390 is pitched squarely against the C-130.
The only true analogues still being built are China's Y-20 and Russia's IL-76, neither
of which is an option for existing C-17 operators.
That leaves existing airframes carrying an increasing load, with the Air Force currently
planning to fly the type until 2075, by which point it will have been in service for 80
years.
Air Mobility Command's deputy commander said in February that the aircraft has done far
more than anyone planned when it was bought, but that it is getting old and that a gap
in strategic airlift simply is not an option.
The intended successor, the Next Generation Airlift Program, aims to replace both the
C-17 and the larger C-5 Galaxy with a single new design, and current planning does not
have it flying operational missions until around 2040, meaning the C-17 has to carry
the load for at least another decade and a half, regardless of what Congress decides
on a restart.
Boeing says existing operators have been approaching it directly about restarting production, and
the company has described those conversations as encouraging.
India is the most concrete case since its Soviet-era Il-76 fleet carries roughly 28
tons against the C-17's 77.5, and is increasingly hard to sustain, with Indian reporting suggesting
the Air Force would seek around five more aircraft if a line reopened.
Japan has expressed interest too.
The obstacle is money and industrial capacity rather than demand.
Boeing sold the original Long Beach factory outright in 2019.
So a restart means a new site, rebuilt tooling, and a supplier base that has sat idle for
over a decade.
RAND's independent analysis put the cost of simply resuming baseline production at
between $2.1 and $2.7 billion in 2011 money, depending on surviving tooling, rising to
for an improved variant with new engines and landing gear, with billions more required
on top of that to actually build aircraft.
Inflation alone would push all of those figures significantly higher today.
The Air Force's assessment is due to Congress by March 2027, and is required to cover tooling
status, supplier viability, workforce availability, delivery timelines, and alternatives, including
So what do you think?
Is restarting a decade-cold production line worth it, or should that money go straight
into a genuinely new airlifter instead?
