In the 2007 defense spending bill, just signed into law by President Bush, Congress approved the Air Force’s controversial multiyear procurement plan for the F-22A Raptor. According to the conference report, House and Senate appropriators agreed to an MYP for 60 aircraft, beginning with 20 in Fiscal 2007 and followed by 20 each in 2008 and 2009. They also stated that they “expect the Department of the Air Force will continue to seek improved efficiencies in this program.” The Air Force believes the MYP will save money, considering the overall reduced buy of the new stealth fighters, but, more importantly, would extend the fifth-generation production line should there be a delay with the F-35.
The Air Force overall reduced its size by 120 aircraft in fiscal year 2021, but kept about the same number of fighter, bomber and attack aircraft, according to data supplied by the service. The F-35 fleet saw the biggest increase while the B-1B bomber fleet saw the largest decline.
