With the U.S. Air Force revealing concept art and a designation for its shadowy Northrop Grumman B-21 Long Range Strike-Bomber (LRS-B) last week, there are many details that we can now glean about the new warplane.First and foremost, the new B-21 looks very similar to its B-2 Spirit predecessor. In fact, the new aircraft look startlingly similar to the original Advanced Strategic Penetration Aircraft (ASPA) and the later Advanced Technology Bomber concept from the 1980s that ultimately resulted in the B-2.
