It can be said that the B-2 actually derives more from the Horten brothers' flying wing designs and prototypes of late WWII - there are many design
similarities, and although the concept of radar absorption and deflection away from the transmitter/receiver was initially fully explored by the Have
Blue, the initial aircraft project itself was almost entirely German in origin. There is a clear line of design philosophy from the Horten IX through
to the B-2. (The Northrop flying wing, in my opinion, was not the predecessor of the B-2).
Northrop's b-2 was developed on its own, not from the wing or german plane, the stealth in the german plane was crude and radars were crude then so
it couldnt have descended to the b-2, the desighns and performances r the same thats all.
The Northrop B-2's design originally came from a "form follows function" philosophy, and indeed is claimed by the Chief Designer of Northrop's B-2
(Irv Waaland) to have originated on Northrop's ATB drawing boards after 6 weeks of design analysis to meet the requirement of both stealth, heavy
lift capabilities and low altitude penetration.
The claim not only disassociates Northrop's B-2 from the Horten designs but also from the Northrop YB-49 designs - with the small exception that the
YB-49 test pilots were questioned about YB-49 flight test experiences and ground handling... but this came
after the B-2 design was decided
upon.
Some in the aerospace engineering community find this a hard pill to swallow seeing how it was known at the end of WW2 that the Horten and subsequent
Northrop YB-49 flying wing designs were stealthy to radar signals.
The reality seems to be that the B-2A design developed at Northrop's own version of Skunkworks, known as the Advanced Design Area is probably
influenced by all, but not developed from or based on any of the earlier flying wing designs... but that is conjecture.
In fact the original drawing-board concept of the B-2 was actually diamond shaped, but it underwent a major re-design to the now familiar "ww"
trailing edge bat-shape due to a change in USAF stated mission profile requirements from high altitude target ingress to low altitude TFR ingress.
Two other factors to consider that are key to the B-2's design, that were for all intents and purposes non-existent during the days of Horten's and
Jack Northrop's early 'wings', are digital computers and composite material technology. These, combined with the tail-less planform, make the B-2
what it is - stealthy.
One additional note in a book by Jay Miller on the B-2 the following touching anecdote is mentioned:
"Jack Northrop was still alive but in poor health early in the ATB/B-2 program.
He was around 86 years old. He was not consulted on the ATB/B-2 design, but
Northrop corporate management requested special clearance for Jack to see the
B-2 design. The USAF granted this request as an honor to Jack. In a small
luncheon in the Hawthorne Advanced Design Area, they showed Jack Northrop a
small model of the ATB/B-2 design. He of course was quite touched and he asked
lots of questions about the ATB/B-2 and people were impressed as he contrasted
it with the details of the YB-49, which he still remembered. Jack said that
now he knew why he had been kept alive all these years. He died one year later."
