There is a proposal under consideration to re-engine the remaining B-52H aircraft to extend the service life. B-52 re-engine plans, if implemented, call for the B-52 to be utilized through 2025. Current engineering analysis show the B-52's life span to extend beyond the year 2040. The limiting factor of the B-52's service life is the economic limit of the aircraft's upper wing surface, calculated to be approximately 32,500 to 37,500 flight hours. Based on the projected economic service life and forecast mishap rates, the Air Force will be unable to maintain the requirement of 62 aircraft by 2044, after 84 years in service මේන් ඇමරිකාව</blockquote>
