After some scrubbed makes an attempt, NASA’s X-59 QueSST flew for the primary time from Air Pressure Plant 42 in Palmdale on Oct. 28, 2025.
In a landmark milestone for aeronautical analysis, NASA’s experimental X-59 QueSST (Quiet SuperSonic Know-how) carried out its maiden flight as we speak. The plane, designed and constructed by Lockheed Martin’s Skunk Works on the Air Pressure Plant 42 in Palmdale, California, shall be used to pave the best way for the return of supersonic airliners.
The sortie has been deliberate to test vital onboard programs, in addition to verifying system integration, dealing with qualities, avionics, instrumentation. The primary flight additionally permits for the brand new plane to maneuver from Palmdale to NASA’s Armstrong Flight Analysis Heart on the close by Edwards Air Pressure Base. After take-off, the plane quickly climbed to the highest of Flightradar24’s ‘most tracked’ plane listing with tens of 1000’s of individuals following the maiden flight.

This milestone now marks the transition from floor testing to airborne operations in NASA’s push towards quiet supersonic flight. The info gathered from the X-59 flights will assist the FAA and worldwide regulators consider potential adjustments to current guidelines that at present prohibit civilian supersonic flight over land.

The truth is, the FAA is getting ready to exchange the decades-old ban with new noise-based certification requirements. This follows the White Home’s government order in June 2025 which directed the FAA to repeal the ban to permit overland supersonic flights for civilian plane.
On Oct. 27, the QueSST was named as 2025’s ‘Coolest Factor Made in California’.

Transferring to the First Flight
From the outset, the mission was designed to stay comfortably inside subsonic boundaries. Fairly than chase velocity or altitude information, the emphasis was on verifying system integration, dealing with qualities, avionics, instrumentation, and structural habits beneath actual aerodynamic masses.
NASA had already stated final month that the primary flight would take the type of a lower-altitude loop at about 240 mph (210 knots) and attain round 12,000 ft, with an approximate length of 1 hour. The check crew is mapping each step from taxi and takeoff to cruising and touchdown, and, throughout subsequent check flights, the X-59 will go increased and quicker, ultimately exceeding the velocity of sound.
All through the primary and the next flights, the X-59’s Flight Check Instrumentation System (FTIS) will acquire and transmit audio, video, knowledge from onboard sensors, and avionics info. The pilot and floor crew may also monitor engine response, aerodynamic dealing with, management authority, air knowledge programs, telemetry integrity, and system redundancy.
“We file 60 completely different streams of information with over 20,000 parameters on board,” stated Shedrick Bessent, NASA X-59 instrumentation engineer. “Earlier than we even take off, it’s reassuring to know the system has already seen greater than 200 days of labor.”
Security Measures
Behind the X‑59’s superior programs is a devoted crew of engineers, technicians, and security and high quality assurance consultants. Central to this crew is the crew chief, chargeable for sustaining the plane and making certain it’s totally prepared for flight.
“I attempt to all the time stroll up and shake the crew chief’s hand,” beforehand stated Nils Larson, NASA X‑59 lead check pilot. “As a result of it’s not your airplane – it’s the crew chief’s airplane – and so they’re trusting you with it. You’re simply borrowing it for an hour or two, then bringing it again and handing it over.” For the primary flight, NASA stated Larson would certainly be borrowing the plane from Matt Arnold of Lockheed Martin and Juan Salazar from NASA.
The X‑59 is supplied with a number of programs designed particularly to guard the pilot. Its life help system delivers oxygen to compensate for low atmospheric stress at altitudes round 55,000 ft, whereas additionally powering Larson’s g‑swimsuit. As one other security layer, the plane options an ejection seat and cover tailored from a U.S. Air Pressure T‑38 coach, outfitted with necessities equivalent to a primary support equipment, radio, and water.
“All these programs type a community of security, including confidence to the pilot and engineers as we method first flight,” Larson stated. “There’s a number of belief that goes into flying one thing new. If the engineers belief the plane and I belief them, then I’m all in.”
What it Achieved
In NASA’s phrases, the primary flight “kicks off a primary section of flight testing centered on verifying the plane’s airworthiness and security.”
Though modest in efficiency envelope, the primary flight is vital for a number of vital validations. Amongst these are engine habits, management floor responsiveness and authority, stability and dealing with habits beneath predicted aerodynamic masses.
Different vital validations will contain the touchdown, probably the most vital phases of flight. That is very true because the X-59 has an elongated nostril which makes up for a 3rd of the jet’s complete size.
The nostril is an important a part of the X-59, designed to manage the aerodynamic stress waves, resulting in quieter sonic booms. Nonetheless, this additionally reduces the visibility, and the plane has been geared up with the eXternal Imaginative and prescient System (XVS), which provides quite a lot of cameras changing a ahead cockpit window.
Background & Preparatory Work
The trail to flight concerned a number of key steps, as we lined beforehand right here at The Aviationist. In January 2024, we reported on the X-59 rollout at Lockheed Martin’s Skunk Works in Palmdale. Later, in November 2024, we lined the engine check milestone, when the X-59’s propulsion system was powered for the primary time.

Following rollout and engine testing, this system carried out low-speed taxi assessments starting in July 2025, validating steering, braking, and stability on the bottom in preparation for flight. Extra floor operations included high-speed taxi till early this month.
On the modeling facet, superior computational approaches had been additionally used to simulate numerous facets and programs. A few of these had been additionally examined in dwell situations, just like the XVS which was examined on NASA’s Beechcraft King Air UC-12B.
