The Pentagon has been looking for a new model to replace them, and Northrop Grumman has won for the next half-century with a major new order for state-of-the-art bomber aircraft. The bomber will be capable of carrying nuclear weapons, and the contract is worth almost $60 billion. The Atlantic reports, "While the current fleet remains useful, the Air Force wants a bomber that can evade the advancing air defenses of Russia and China—if ever the need arises. The long-range bomber would act as a deterrent against actions designed to keep U.S. forces out of a designated area—what the military calls 'anti-access aerial denial.'"
