A restart decision hinges on two numbers Tulley did not provide: the unit cost of a restarted airframe and the calendar time to restart the line. If restart costs exceed $400M per airframe (the historical unit cost adjusted for inflation and tooling restart), the case for C-17 production competes directly with NGAL acceleration — same O&M dollar pool, different timelines.
The deeper constraint is that Boeing's Long Beach facility is now fully committed to KC-46 tanker production; restarting C-17 either delays tanker deliveries (which AMC also needs urgently) or requires a second facility. That facility cost is not in Tulley's calculus yet, but it will be in the Analysis of Alternatives report.
The Air Force is confronting a capacity math problem it cannot solve with service-life extensions alone.
The Iran conflict has burned through airlift sorties at a pace the current C-17 fleet cannot sustain — a reality that forces AMC to compress the NGAL development timeline or accept a ten-year gap where the C-17 fleet ages without replacement. Tulley's explicit question about restart cost and the machinery-preservation problem signals that the service is serious about the option, not just exploring it theoretically. Watch whether the FY27 FYDP includes an Analysis of Alternatives contract with a Boeing restart cost estimate — that filing would confirm the timeline is slipping.
What is the current C-17 utilization rate in Operation Epic Fury, and has it exceeded the peacetime sortie-generation assumptions baked into the mid-2040s NGAL schedule?
