Over the last few months following various websites it suprises me how much about the new B-21 is being talked about. Secretary of the Air Force Frank Kendall talked about how five of them are in final assembly. The B2 was first flown in 1989 and was so secret that maybe a dozen people in total knew about it. The F-117A flew for close to 10 years before any real acknowledgment of its existence. It seems odd how out in the open its existence has been. Secondly how much stealthier can we get? Supposedly when the B2 Spirit debuted it was the size of a small bird, the F-22 was said to be the size of a bee. What's everyones thoughs on this. I figured it would have been a decade or longer before any information would have come out on its existence.
