Retired Colonel Richard Sheffield has published a memoir detailing the factors behind the U.S. Air Force decision to retire the SR-71 Blackbird. The aircraft was officially decommissioned in January 1990.
Why it matters
The memoir highlights how the Air Force prioritized the F-22 contract over the reconnaissance platform. It also notes shifting leadership preferences toward satellite intelligence assets over manned aircraft.
The SR-71 operated at altitudes of 80,000 feet and reached speeds of Mach 3.2. Operational costs for the 10-aircraft fleet totaled $200 million per year.
