Estimates for the fighter jet range from as little as $132 million to as much as $312 million. So far, the Air Force has invested as much as $28 billion in the Raptor's research, development and testing. That money, referred to as a "sunk cost," is already spent and is separate from money used for future decision-making, including procuring a copy of the jet.
By the time all 183 jets have been purchased, around $28 billion will have been spent on research and development. An additional $34 billion will have been spent on actually procuring the aircraft. That's about $62 billion for the total program cost. Divided out, that's comes to about $338 million per aircraft.
But the reality is, if the Air Force wanted to buy just one more jet, it would cost the taxpayer less than half that amount. The current cost for a single copy of an F-22 stands at about $137 million. And that number has dropped by 23 percent since Lot 3 procurement, General Lewis said.
"The cost of the airplane is going down," he said. "And the next 100 aircraft, if I am allowed to buy another 100 aircraft ... the average fly-away cost would be $116 million per airplane."
Our government has no mandate if it cannot defend us.
