Boeing's design features a composite wing body inspired by the success of the X-48.
Northrop Grumman
Northrop Grumman
Northrop Grumman also chose to go with an aerodynamic flying wing design, one with four Rolls Royce engines implanted within the aircraft’s upper surfaces that looks like the company’s earlier B-2.
Lockheed Martin Boxed Wing
Lockheed Martin Boxed Wing
Lockheed Martin’s proposal looks quite different, relying on a boxed wing design and a Rolls Royce Liberty Works Ultra Fan Engine with a bypass ratio 5 times higher than technology in use today.
Supersonic Aircraft

Double Bubble D8
Double Bubble D8
The Double Bubble D8 is a design undergoing testing at MIT.
Double Bubble D8
Double Bubble D8
The design features low-swept wings and a wide fuselage.

GE Turboprop
GE Turboprop
This turboprop design, put forth by GE, is constructed to fly at Mach 0.55 while carrying 20 passengers.
SELECT
SELECT
SELECT, a design submitted by Northrop Grumman, would rely on ceramic composite materials and shape memory alloys.
Boeing Volt
Boeing Volt
The Boeing Volt is a hybrid model that relies on gas turbine and battery technology.
