Mechanical technician Dan Pitts prepares a scale model of Lockheed Martin's Quiet Supersonic Technology (QueSST) X-plane preliminary design for its first high-speed wind tunnel tests at NASA's Glenn Research Center.

NASA's F/A-18 research aircraft takes off from Ellington Field in Houston, Texas for a quiet supersonic research flight off the coast of Galveston, as part of the QSF18 flight series. The F/A-18 will climb to 50,000 feet over the Gulf of Mexico, where it will perform the quiet supersonic dive maneuver.

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.

NASA Administrator Bridenstine stands with AFRC center director McBride by model NASA's Supersonic X-Plane, X-59 Quiet Supersonic Technology or QueSST. Bridenstine spoke at press event at Mojave Air and Space Port in California. The goal of X-59 is to quiet the sound when aircraft pierce the speed of sound and make a loud sonic boom on the ground.

While the quiet supersonic dive maneuver produces a quieter version of the sonic boom in a necessary area, it produces a loud sonic boom out over the ocean. Doing so over the busiest waterway in the country makes it necessary to provide high levels of situational awareness to vessels below, through communications between NASA public affairs officers and the U.S. Coast Guard command center.

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.

A technician is working on the engine inlet of NASA’s X-59 Quiet Supersonic Technology (QueSST) aircraft at Lockheed Martin’s Skunk Works facility in Palmdale, California.

Following the successful installation of mounting brackets, technicians successfully installed the pallet for the eXternal Visibility System, or XVS, onto the X-59 Quiet SuperSonic Technology X-plane, also known as X-59 QueSST. The pallet installation marks an assembly milestone as the first NASA flight systems hardware to be installed onto the vehicle. X-59 will fly to demonstrate the ability to produce quiet thumps at supersonic speeds, instead of the typical, loud sonic booms associated with supersonic flight.

NASA test pilots perform the quiet supersonic dive maneuver off the coast of Galveston, Texas to create a quieter version of the sonic boom, in order to obtain recruited community survey feedback data. The test pilot climbs to around 50,000 feet, followed by a supersonic, inverted dive. This creates sonic boom shockwaves in a way that they are quieter in a specific area. Meanwhile, NASA researchers match community feedback to the sound levels of the flights, using an electronic survey and microphone monitor stations on the ground. This is preparing NASA for community response models for the future X-59 QueSST.

Following the successful installation of mounting brackets, technicians successfully installed the pallet for the eXternal Visibility System, or XVS, onto the X-59 Quiet SuperSonic Technology X-plane, also known as X-59 QueSST. The pallet installation marks an assembly milestone as the first NASA flight systems hardware to be installed onto the vehicle. X-59 will fly to demonstrate the ability to produce quiet thumps at supersonic speeds, instead of the typical, loud sonic booms associated with supersonic flight.

NASA test pilot Jim Less prepares to exit the cockpit of the quiet supersonic X-59 aircraft in between electromagnetic interference (EMI) testing. The EMI testing ensures an aircraft’s systems function properly under various conditions of electromagnetic radiation. The X-59 is the centerpiece of the NASA’s Quesst mission, designed to demonstrate quiet supersonic technology and provide data to address a key barrier to commercial supersonic travel.

NASA’s X-59 quiet supersonic research aircraft sits inside its run stall in preparation for maximum afterburner testing at Lockheed Martin’s Skunk Works facility in Palmdale, California. Teams conduct final checks on the aircraft before its high-thrust engine runs. The X-59 is the centerpiece of NASA’s Quesst mission designed to demonstrate quiet supersonic flight over land, addressing a key barrier to commercial supersonic travel.

The X-59 Quiet SuperSonic Technology (QueSST) aircraft is taking shape at the Lockheed Martin Skunk Works facility in Palmdale, California. The team positioned the X-59 QueSST's nose at the front of the aircraft. As one of the more recognizable features of the X-59, the nose makes up almost a third of the aircraft length and will be essential in shaping shock waves during supersonic flight, resulting in quiet sonic thumps instead of loud sonic booms. The nose was attached and then removed from the front of the aircraft in preparation for its shipment to Fort Worth, Texas where it will undergo additional testing. The X-59 will fly at supersonic speeds above communities as part of the Low-Boom Flight Demonstration mission, during which NASA will gather community feedback to the sound of quiet supersonic flight. These findings will be shared with regulators to inform decisions on current restrictions of supersonic flight over land.
