NASA’s X-59 quiet supersonic research aircraft is unveiled at a January 12, 2024 event at Lockheed Martin Skunk Works in Palmdale, California. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land, currently banned in the United States, by making sonic booms quieter.
This is an overhead view of the X-59 aircraft at Lockheed Martin Skunk Works in Palmdale, California. The nose was installed, and the plane awaits engine installation. Technicians continue to wire the aircraft as the team preforms several system checkouts to ensure the safety of the aircraft. The X-59 aircraft will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump and help enable commercial supersonic air travel over land.

A new supersonic probe seen affixed to a F-15B flight test fixture might one day measure the sonic booms of a new generation of supersonic aircraft.
The CISBoomDA display allows the pilot of a supersonic aircraft to monitor the locations of any sonic booms produced, to prevent the aircraft from positioning booms in restricted area.
NASA's F-15B Research Testbed aircraft recently flew in the supersonic shock wave of a U.S. Navy F-5E in support of the F-5 Shaped Sonic Boom Demonstration (SSBD) project, part of the Defense Advanced Research Projects Agency's (DARPA) Quiet Supersonic Platform (QSP) program. The flights originated from the NASA Dryden Flight Research Center at Edwards, California. Four flights were flown in order to measure the F-5E's near-field (close-up) sonic boom signature at Mach 1.4, during which more than 50 shockwave patterns were measured at distances as close as 100 feet below the F-5E.

The pilot of NASAÕs X-59 Quiet SuperSonic Technology, or QueSST, aircraft will navigate the skies in a cockpit unlike any other. There wonÕt be a forward-facing window. ThatÕs right; itÕs actually a 4K monitor that serves as the central window and allows the pilot to safely see traffic in his or her flight path, and provides additional visual aids for airport approaches, landings and takeoffs. The 4K monitor, which is part of the aircraftÕs eXternal Visibility System, or XVS, displays stitched images from two cameras outside the aircraft combined with terrain data from an advanced computing system. The two portals and traditional canopy are real windows however, and help the pilot see the horizon. The displays below the XVS will provide a variety of aircraft systems and trajectory data for the pilot to safely fly. The XVS is one of several innovative solutions to help ensure the X-59Õs design shape reduces a sonic boom to a gentle thump heard by people on the ground. Though not intended to ever carry passengers, the X-59 boom-suppressing technology and community response data could help lift current bans on supersonic flight over land and enable a new generation of quiet supersonic commercial aircraft.

The stabilators, the outer surfaces also seen in the photo, attach to the lower empennage and are used to help regulate the aircraft pitch which controls the up and down movement of the motion of the plane. The 13-foot engine will pack 22,000 pounds of propulsion and energy and power the X-plane to its planned cruising speed of Mach 1.4. Once complete, the X-59 aircraft will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump and help enable commercial supersonic air travel over land.

The X-59’s nose is 38-feet long – approximately one third of the length of the entire aircraft. The aircraft, under construction at Lockheed Martin Skunk Works in Palmdale, California, will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump.

This is an up-close view of the X-59’s engine inlet – fresh after being painted. The 13-foot F414-GE-100 engine will be placed inside the inlet bringing the X-59 aircraft one step closer to completion. Once fully assembled, the X-59 aircraft will begin flight operations, working toward demonstration of the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump, helping to enable commercial supersonic air travel over land.
NASA’s X-59 quiet supersonic research aircraft sits outside Hangar 4826 at NASA’s Armstrong Flight Research Center in Edwards, California, on Nov. 19, 2025. The aircraft’s arrival at NASA Armstrong on Oct. 28, 2025, marked its transition into flight operations in support of NASA’s Quesst mission to gather data on quiet supersonic flight.
NASA’s X-59 quiet supersonic research aircraft during engine run testing on Thursday, March 12, 2026, at NASA’s Armstrong Flight Research Center in Edwards, California. Engineers and technicians monitored the aircraft’s systems as the engine powered up, gathering data to verify performance and prepare the X-59 for its next series of experimental flights. The X-59 will support NASA’s Quesst mission, which aims to demonstrate technology that can reduce the loud sonic booms of supersonic flight.
A Lockheed Martin technician prepares holes for installation of the fuselage panel on the X-59. The fuselage is the section of the aircraft that contains the cockpit. The aircraft, under construction at Lockheed Martin Skunk Works in Palmdale, California, will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump.
NASA’s X-59 test pilot Mike Lippert stands in front of the agency's X-59 quiet supersonic research aircraft at NASA's Armstrong Flight Research Center in Edwards, California, on Wednesday, June 24, 2026. Lippert joins NASA as the third X-59 pilot supporting the Quesst mission, which will eventually fly over U.S. communities to demonstrate quiet supersonic flight and collect feedback from the public about the aircraft’s quiet sonic “thump.”
NASA’s X-59 quiet supersonic research aircraft flies above NASA’s Armstrong Flight Research Center in Edwards, California, during testing focused on lower-speed and lower-altitude flight conditions in support of NASA’s Quesst mission. NASA continues two-flight days during envelope expansion testing as teams work to better understand how the aircraft responds throughout its operating range.
NASA’s X-59 quiet supersonic research aircraft sits inside Hangar 4826 at NASA’s Armstrong Flight Research Center in Edwards, California, on Nov. 18, 2025. Following its first flight on Oct. 25, 2025, in support of NASA’s Quesst mission, the aircraft entered scheduled maintenance as part of its transition into flight operations. Quesst aims to demonstrate quiet supersonic flight and reduce the disruptive sonic boom to a quieter sonic thump.

NASA's F-15B research testbed jet from NASA's Dryden Flight Research Center flew in the supersonic shockwave of a Northrop Grumman Corp. modified U.S. Navy F-5E jet in support of the Shaped Sonic Boom Demonstration (SSBD) project, which is part of the DARPA's Quiet Supersonic Platform (QSP) program. On Aug. 27, 2003, the F-5 SSBD aircraft demonstrated a method to reduce the intensity of sonic booms.
