Supersonic business jet planned by Lockheed Martin
Gulfstream Aerospace | November 23, 2016
The single-engine Mach 1.4-plus X-Plane is intended to mimic the shockwave signature of a 100-120-seat supersonic airliner and show that a shaped sonic boom is quiet enough to permit supersonic flight over land. Gulfstream Aerospace, which is part of NASA’s consulting review panel on the project, has been conducting its own preliminary design studies for a supersonic business jet.
