US bomber B-21 creates a sensation

The US Air Force has created a worldwide sensation when it unveiled the first rough design of its under-development long-range strike bomber, tentatively named 'B-21'. The futuristic military aircraft will be developed at a cost of $80 billion by Northrop Grumman. However, there are no existing prototypes of the aircraft. The US Air Force will procure around 100 B-21s, the futuristic jet, at a cost of around $500 million each. The program has been shrouded in secrecy since its inception for fear of revealing military secrets to potential enemies. The all-black plane has a distinctive, zigzagging shape and a super-low profile that will make it hard to spot on the radar. It bears more than a passing resemblance to the Air Force's B-2 bomber, which is also made by Northrop Grumman. The bomber can fire at a target anywhere in the world and return to base.
