U.S. Air Force To Fly B-1B Lancer And B-2 Spirit Well Into Late 2030s
The United States Air Force has no plans to retire its remaining fleet of Boeing B-52 Stratofortress bombers for at least a couple more decades, and the old "BUFFs" as they are known, will be in service until the late 2040s or early 2050s, perhaps even longer. However, even as the Air Force will adopt the Northrop Grumman B-21 Raiders in the coming year, the B-52s won't be the only old workhorses that will remain in the bomber fleet.
