A 2017 Pentagon report to Congress detailing production retail costs for Lockheed Martin’s F-22 Raptor show that reviving the powerful stealth air superiority fighter would be prohibitively expensive. Moreover, it would take so long to reconstitute the production line that it would not be until the mid to late 2020s before the first “new” F-22s would have flown. By that time, the F-22 would be increasingly challenged by enemy—Russian and Chinese—capabilities.
