The US Air Force has unveiled the new B-21 Raider bomber. The manufacturer positions the bomber as the world's only sixth-generation aircraft. According to Northrop Grumman, the aircraft is capable of reaching anywhere in the world, carrying nuclear and conventional weapons, and overcoming the most advanced air defense systems thanks to improved stealth technology. Since the introduction of the B-2 Spirit aircraft, the B-21 Raider has become the first new US Air Force bomber in 34 years. It is reported that using cloud technologies, you can create a "digital twin" of the aircraft, which will help track the performance of combat missions. The B-21 Raider bomber has evolved from the B-2 bomber and should incorporate all the best. As previously reported, the B-21 should become cheaper in terms of purchase and operation costs than its predecessor, the B-2. This should be achieved by reducing the size of the new bomber and its carrying capacity, as well as partial unification with other US Air Force aircraft. The B-21 has been given a more durable surface material for stealth, requiring less maintenance effort and minimizing operating costs and downtime. The price of the aircraft is $750 million. The first flight of the B-21 Raider bomber should take place in 2023. Detailed specifications of the B-21 are classified.
