In response to an earlier thread regarding this
aircraft: Quiet Supersonic Platform

and to address the possibilities of a "B-3" bomber,
I just wanted to give out some other information
which I found and made some discreet inquiries into...
The quiet supersonic platform is a year 2000 program
to create a long range recon AND bomber test aircraft to
explore BOTH passive and active audio & visual stealth technologies.
A contract awarded to Northrop Grumman, McDonnell Douglas
and Lockheed Martin Corp. on November 9, 2000 outlined
a research program for white world acoustic and visual stealth
technologies not only for publically-displayed military
craft but also as a technology demonstrator for commercial
aviation noise reduction in addition to exploring generic
methods to reduce infra-red and visual signatures.
The shape of the aircraft is errily reminsicent of a widened
and flattened B1-Lancer bomber with some added shaping for acoustic
reduction of airflow noise, engine noise and sonic boom reduction
so that long range supersonic cruise in a fuel efficient manner could be realized.

The Quiet Supersonic Platform particular craft is an exercise
in passive audio stealth by custom-shaping engine inlets and
outlets and special reformation of the plane's nose superstructure
so that the shockwave created by supersonic flight can be moved and
then shaped within a flight plane so as to reduce it's acoustic signature.
The inward facing tail fins also shape trailing vortices
so that shockwave formation can be broken up as air pressure
mounts upon the aircraft hull when it approaches the sound barrier.
Again this is a White-World technology demonstrator more geared
for general recon, tactical bombers and commercial aircraft.
The more that 40 Billion Dollar Black Budget for 2008
has a few disbursements for more Active Audio & Visual Stealth
under SAP (Special Access Program) projects that
use DSP (Digital Signal Processing) to emit a 180 degrees out-of-phase
version of a plane's acoustic signature to essentially
cancel out (er...reduce) noise much like what Noise Cancelling Headphones do.
Other acoustic signature reduction technologies include
using high electromagnetic energies to push the atmosphere
away from the hull of the craft so as to create an elongated
virtual airfoil which can also used for aircraft performance
enhancement in addition to audio stealth purposes.
Large super-capacitors that are charged and discharged in a
pulsed manner can create a large electromagnetic field at the leading edges,
wing tips, canards, or any other part of a hull to form a virtual aircraft shape
that can be dynamically changed by pulsing the capacitors at specific
energies and timings. The atmosphere is literally deflected into user-specified
airflow modalities that fit either specific mission profiles or desired
levels of acoustic signature refinement.
If you can shape the airflow into a defined hull shape or engine thrust
outflow shape, it also means you can mimic the acoustic signatures of
common commercial or enemy aircraft.
By also defining specific airflow shapes, you can also define
lift profiles such as extra wide virtual wings for extra lift
or a long slender needle-like shape for extra speed.
Airflow shaping can also be used for reduction or shaping of
heat signatures so as to confuse Surface-To-Air or Air-to-Air missiles
by either masking the infrared profile or shaping the heat signature
profile to mimic another type of aircraft.
