Air Force Considers Reviving C-17 Production to Fill 2041 Capability Gap
The United States Air Force is considering a surprising solution to its 2041 airlift capability gap: restarting production of the Boeing C-17 Globemaster III, an aircraft whose assembly line shut down in 2015. On September 16, Air Mobility Command chief Lt. Gen. Daniel Tulley confirmed that the Air Force is formally evaluating this option as part of the Next-Generation Airlift (NGAL) Analysis of Alternatives. Congress has set a deadline of March 1, 2027, for a feasibility report covering tooling status, supplier viability, and cost.
The current C-17 fleet, consisting of 219 to 222 aircraft out of 279 built, is heavily utilized, with the backup Lockheed Martin C-5M Super Galaxy having just 37% availability. This strain has led the Air Force to explore options, including converting commercial aircraft or waiting for NGAL. However, the C-17's proven capability makes it a compelling option despite the challenges of restarting production.
The primary obstacle is the state of the tooling and the specialized workforce that has moved on since the line's closure. Recovering these resources has been described as "industrial archaeology," requiring the Air Force to determine what tooling still exists and whether it can be used. The cost of restarting production is also a significant factor, with estimates ranging from $2.1 billion to $2.7 billion for the C-17A variant and up to $6.4 billion for a more capable C-17B variant.
The Air Force is also preparing a digital cockpit overhaul for its existing C-17 fleet, as critical mission computers and multifunction displays are expected to run short of spare parts by fiscal year 2027. While reviving old hardware is one option, restarting an old production line presents a much greater challenge. The decision will ultimately hinge on whether the costs and logistical hurdles of restarting the C-17 line are outweighed by the benefits of having additional aircraft to fill the capability gap.
