Warplanes: B-52 Stays, B-1B Retires

The U.S. Air Force has decided to retire its B-1B bombers, which were built in the 1980s, before the B-52Hs, which were built in the 1960s. It’s all about cost. One of the two older heavy bombers has to go when the new B-21 stealth bomber begins entering service in 2030. If that happens the B-1Bs will start to retire in 2025 and the last will be gone by 2035. The B-52s are to serve until the 2040s.
