Potentially the replacement combat search and rescue aircraft program, if it runs through the full 141 aircraft buy, is valued at up to $15 billion. First, though, CSAR-X competition winner Boeing must work through Block 0—system development and demonstration—and delivery of 10 production aircraft to meet the Air Force’s 2012 timetable for initial operational capability. If the Air Force pursues the full procurement, production likely would extend to 2019.
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.
