That type of craft sounds like the Blackworld equivalent of the
Switchblade aircraft which is DIFFERENT than the oft-derided white
world craft that is called Switchblade.
The "Black Budget" Switchblade is supposed to go way beyond simple
variable sweep wing technology into fully deformable wing and
super-structure for both low-and-slow flying plus high-speed
long range attack and bomb.
From what I understand LMCO (Lockheed Martin) is using at least
one technology called "Metallic Glass" :
which has an ability to both flex AND be strong at the same time
in both the wing portions and some body panels.
In some test demonstrators another technology called
Peizo-Actuation on flight surfaces to deform wings to perform
maneuvers that are pretty much beyond the physical capabilities
of a human pilot to take.
These new "Smart Materials" allows aircraft bodies and wings
to deform and change shape based upon sensing the current environment
and surroundings OR change shape based upon the application
of electro-magnetic energies or other type of initiators
or environmental stressors
On a side note we've pretty much WAY EXCEEDED the abilities
of the human body and mind in terms of G-Force loads and cockpit
workload so it's pretty much CUAV and remote piloting that will
BE THE FUTURE of aerial warfighting.
