The B-21 Raidermanufactured by Northrop Grumman, is the new US Air Force nuclear bombersthe first to be built more than thirty years after the B-2 Spirit’s launch in 1988. It costs $692 million – the US Air Force plans to buy at least a hundred – and It is the most advanced fighter aircraft ever developed: It can carry both long-range nuclear and conventional warheads and is capable of penetrating enemy air defense lines and conducting strikes anywhere in the world. Above all, it is difficult to identify by enemy radar. And all of these features were made possible through the use of artificial intelligence.
