The Number of F/A-22s Set at 183: 
USAF officials say the QDR will limit F/A-22 Raptor production to 183 aircraft (number corrected from 185 following official USAF briefing on 12/13/05). They plan to extend the production line—allowing a peak rate of 20 per year. Stretching the program this way will enable them to bridge the gap to start of F-35 Joint Strike Fighter production, but they admit it will drive the per unit cost of the Raptor higher.
The Air Force has embraced new technical approaches like open mission systems and rapid software updates for cutting-edge aircraft like the B-21 and Collaborative Combat Aircraft. Increasingly, though, the service is also working to apply these to its older, “legacy” aircraft, officials said this week.
