Procurement of F-22s began in FY1999, and a total of 195 (177 production aircraft, 16 test aircraft, and 2 development aircraft) were procured through FY2009. Recent Developments

		F-22 Oxygen Issues

Following a November 2010 fatal crash of an F-22 in Alaska, the Air Force began an effort to understand why pilots were "reporting hypoxia-like symptoms in the air. At least 25 "physiological incidents" were recorded among F-22 pilots; 14 prior to the Raptor being grounded from May to September 2011, for investigation of the issue, and at least 11 subsequently. FY2013 F-22 Funding

The Administration's proposed FY2013 defense budget requests $283.9 million in FY2013 procurement funding for modification of in-service aircraft and $36.7 million to equip Air Logistics Centers to perform F-22 maintenance. The Senate Appropriations Committee mark of H.R. In August 2012, the Air Force announced that the oxygen deprivation issue was due to "a 'mosaic' of interrelated cockpit equipment issues that led to a chain reaction of glitches resulting in symptoms similar to hypoxia." The Administration's proposed FY2013 defense budget also requests a new start program, funded at $140.1 million in research and development, for the Increment 3.2B software; and $371.7 million in FY2013 research and development funding for F-22A Squadrons. FY2013 Defense Appropriations Bill (H.R. None of the funds made available in this Act may be used to approve or license the sale of the F-22A advanced tactical fighter to any foreign government: Provided, That the Department of Defense may conduct or participate in studies, research, design and other activities to develop a future export version of the F-22A that protects classified and sensitive information, technologies and U.S. warfighting capabilities.
Procurement of Air Force F-22 Raptor fighters began in FY1999, and a total of 195 (177 production aircraft, 16 test aircraft, and 2 development aircraft) were procured through FY2009. In the FY2010 budget, the Administration proposed to end F-22 procurement at 187, and Congress approved that termination. The F-22 assembly line in Marietta, GA, has been shut down, with its tools and equipment placed in storage.
Since 2010, operational issues have arisen. Following a November 2010 fatal crash of an F-22 in Alaska, the Air Force recorded at least 25 "physiological incidents" of F-22 pilots reporting hypoxia-like symptoms while flying, possibly indicating oxygen deprivation. Following a lengthy investigation and grounding of the F-22 fleet, the Air Force attributed the oxygen deprivation to "a 'mosaic' of interrelated cockpit equipment issues." Following corrective actions, the F-22 fleet has returned to the air.
The Administration's proposed FY2013 defense budget requests $283.9 million in FY2013 procurement funding for modification of in-service aircraft and $36.7 million to equip Air Logistics Centers to perform F-22 maintenance. The Administration's proposed FY2013 defense budget also requests a new start program, funded at $140.1 million in research and development, for the Increment 3.2B software, and $371.7 million in FY2013 research and development funding for F-22A Squadrons.
The Senate Appropriations Committee markup of the FY2013 defense appropriation bill includes language prohibiting funds from being used to approve or license the sale of the F-22 to other countries. The bill does permit the Department of Defense to conduct studies and design activities to develop a future export version of the aircraft that protects classified and sensitive information. This language is similar to provisions passed by Congress each year since 1998.
