The Air Force has worked up some numbers on what it will cost to add F-22s to the fleet beyond the three-year multiyear buy of 60 aircraft.

Boosting the one-year buy to 24 aircraft would cost $4.25 billion, for a flyaway cost of $144.2 million, or a per-airplane savings of about $9 million. The numbers come from an unclassified briefing given to staffers on Capitol Hill last week. The service is still working up the cost of a four-year multiyear at 24 per year—which would bring the fleet up to 283 aircraft—but service officials said they think doing so would trim unit costs by as much as $25 million per airplane.
