X-59 Supersonic Plane

Quieting the Sonic Boom

In collaboration with NASA's Quesst Mission, the Lockheed Martin Skunk Works® team is solving one of the most persistent challenges of supersonic flight – the sonic boom.

The X-59 will be used to collect community response data on the acceptability of a quiet sonic boom generated by the unique design of the aircraft. The data will help NASA provide regulators with the information needed to establish an acceptable commercial supersonic noise standard to lift the ban on commercial supersonic travel over land.

This advancement would open the door to an entirely new global market for aircraft manufacturers, enabling passengers to travel anywhere in the world in half the time it takes today. 

Breakthroughs Achieved:

  • First flight
  • More than a dozen flights at subsonic test points
  • First supersonic flight
  • First mission conditions flight at Mach 1.4 and 55,000 ft
One Step Closer to Quiet Supersonic Flight   ___
On Oct. 28, 2025, X-59 flew for the very first time. From takeoff at our Skunk Works’® Palmdale facility to landing at NASA's Armstrong Flight Research Center, everything performed exactly as planned.
