SENIOR PEG is Lockheed’s entry in the B-2 stealth bomber design competion of the 1980s. The Lockheed entry was developed based on the Echo One (Hopeless Diamond) angular-faceted stealth-RCS reduction codec and resembles the Skunkworks earlier F-117 and Have Blue prototypes design philosophy, except it bore a large twin V-tail located on a boom aft of the trangular flying-wing.
