The Northrop Grumman-designed prototype LRS-B B-3 (Long Range Strike Bomber B-3).
Artist’s rendering of the LRS-B B-3 flying east over Area 51.
Reportedly, this prototype has been replaced by a newer Northrop Grumman design, designated the B-21.
But, I haven’t seen any pictures of the B-21 that are as cool as the one above.
(you know, where the government keeps the bodies of the aliens
captured after the flying-saucer crash in Roswell, New Mexico).
