NASA’s X-59 experimental aircraft reached a major milestone Friday, June 5, when it flew faster than the speed of sound for the first time.  

The 81-minute flight achieved a speed of Mach 1.1 (approximately 713 mph) at an altitude of 43,400 feet, with the X-59 performing as expected. For NASA test pilot Jim “Clue” Less, the plane’s instruments were the only indication of flying supersonic — exactly what the team wanted. 

“You know you are supersonic when gauges say you are supersonic. I didn’t feel anything,” Less said. “It went smoothly, and we easily got to Mach 1.1.” 

The X-59 is designed to fly at supersonic speeds while creating only a quiet thump instead of a loud sonic boom. For this flight, a NASA F‑15 chase plane flew nearby to monitor the test. Its loud sonic booms obscured any sound made by the X-59. The X-59 will conduct flights focused on its sound profile during a later phase of testing. 

Now that the X-59 has officially kicked off supersonic flight tests, the next big step is its first mission conditions flight. During this test, the X-59 will fly at the same speed and altitude planned for future tests, where the aircraft will fly over several U.S. communities to gather data from people on the ground about its noise levels: Mach 1.4 (925 mph) at 55,000 feet.  

“The plane wants to go faster, and we are looking forward to that,” Less said. 

The X-59 is the centerpiece of NASA’s Quesst mission, which aims to demonstrate quieter supersonic flight and to help enable commercial supersonic flight over land.  

This flight was also the first time the X‑59 appeared in NASA’s flight tracker.

NASA’s experimental X-59 aircraft marked a major milestone Friday, June 5, when it flew faster than the speed of sound for the first time, setting the stage for demonstrating its quiet supersonic capabilities later this year. 

NASA test pilot Jim “Clue” Less took off and landed at Edwards Air Force Base in California, reaching a top speed of approximately Mach 1.1 (713 mph) and altitude of 43,400 feet. The X-59’s flight began at 11:08 a.m. PDT and lasted 81 minutes, with the team focusing on flying qualities at both subsonic and then supersonic speeds.  

”X-59 is getting ready for its quiet supersonic debut. Since the aircraft’s first flight on Oct. 28, 2025, the team has made tremendous progress, flying 16 times in the last 90 days and getting into a steady test rhythm. In the coming days, we expect to take the next step and push to Mach 1.4,” said NASA Administrator Jared Isaacman “I’m grateful to the NASA team and Lockheed Martin Skunk Works for their help getting us to this point, and I hope this is the first of many collaborations as we rebuild NASA’s X-plane portfolio.” 

The X-59 is designed to fly at supersonic speeds while creating only a quiet thump instead of a loud sonic boom. For this flight, a NASA F‑15 chase plane flew nearby to monitor the X‑59. The loud sonic booms from the F-15 obscured any sound made by the X-59.  

“The X-59’s first supersonic flight is a testament to America’s enduring leadership in science, engineering, and aerospace innovation,” said Michael Kratsios, Assistant to the President for Science and Technology and Director of the Office of Science and Technology Policy. “This achievement comes as the Trump Administration continues work to unleash supersonic flight and enable American ingenuity.” 

This first supersonic flight is a significant milestone, but an event even more critical to the mission is upcoming. In just days, the aircraft is expected to make its first “mission conditions” flight, reaching a cruising speed of Mach 1.4 (925 mph) and altitude of approximately 55,000 feet. The X-59 also will be accompanied by a chase plane for this flight.  

This speed and altitude are the base conditions for the X-59 when it will eventually fly over several U.S. communities enabling NASA to gather data about how people may perceive its quiet thump. NASA will share this data with U.S. and international regulators to help establish new data-driven noise standards to enable a future viable market for supersonic commercial flight over land. 

For the last several months, the X-59 has been participating in an ongoing series of flights where the plane has been flying at a wide range of speeds and altitudes – a process known as envelope expansion. These tests are the first phase of the X-59’s flight testing. They are focused on performance and involve chase plane monitoring. When the aircraft completes this phase it will enter another, focused on its sound profile in order to verify its quiet thump capability.  

The X-59 is the centerpiece of NASA’s Quesst mission, which aims to demonstrate quiet supersonic flight and help enable commercial supersonic flight over land worldwide. These advancements will help travelers reach their preferred destinations faster, spending less time in the air. 

Through Quesst’s development of the X-59, NASA also will deliver design tools and technology for quiet supersonic airliners that will achieve the high speeds desired by commercial operators without disturbing people on the ground. NASA will validate design tools through ground and flight testing, providing U.S. aircraft manufacturers the ability to explore new quiet supersonic concepts, and provide them with confidence that their resulting designs will meet quiet flight requirements.

Days after successfully flying its Quarterhorse unmanned aircraft at supersonic speeds, an industry-first defense aviation company, Hermeus, has received the largest-ever contract awarded by the Defense Innovation Unit (DIU) to demonstrate high-Mach flight combined with high-Mach payload release.

The new $ 159 million award, which increases the original contract to a total of $219 million, will allow Hermeus’ engineers to expand on previous high-Mach test flight milestones in direct partnership with the U.S. Air Force and the U.S. Navy, with the goal of providing the American warfighter with the most advanced arsenal capable of delivering munitions and payloads around the world at record-setting speeds.

“By delivering flight-ready aircraft and demonstrating payload release at speed, we will prove this technology can create a decisive military advantage on a timeline that matters,” explained Hermeus CEO and co-founder, AJ Piplica. “Our focus is on providing the Air Force and Navy with the validated data they need to transition these platforms into the future force.”

High Mach Payload Release: “A Game Changing Warfighting Capability”

When announcing the new DIU award, Hermeus executives noted that the program will include a series of “intensive flight tests.” The first is expected later this year, while the final flights are expected sometime in 2027.

Although few specifics were provided, the company said the flights will “prove the aircraft can maintain high speeds and expand its performance limits” while also demonstrating the successful carry and release of payloads at high velocity. The company also noted that all flight data gathered during the development and testing phases “will directly inform service experimentation and future acquisition decisions.”

Although the U.S. Military has several aircraft capable of exceeding the speed of sound, and several more hypersonic (exceeding five times the speed of sound) aircraft and missile prototypes, delivering payloads from high-Mach aircraft has remained a challenge. However, some military experts argue that the U.S. would benefit greatly from the capability.

When discussing the need for high-speed payload release, DIU Military Deputy Major General Joe “Solo” Kunkel said that the largest problems the military is facing in the future are “generally around time and distance,” and the associated challenges with getting to distant locations “in a timeframe that matters.”

“I care about the warfighting capability, providing advantage to our partners and us in the fight, and making sure that we can walk into every fight with swagger,” General Kunkel said, adding that mass producing the technology developed by Hermeus could move it from a test platform to a “game-changing warfighting capability.”

“I think we found a significant number of use cases where it can be used as a weapon,” the General added. 

Moving High-Mach Capability Out of the Lab

When discussing the company’s approach that convinced the DIU to offer its largest award in the organization’s history, including what they describe as “reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today,” Hermeus noted that directly partnering with the USAF and USN allows their engineers to align tests with future mission needs and shorten the path from testing to deployment.

“By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield,” the company’s statement explained. “We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.”

When discussing the significance of the upcoming tests and the overall need for high-Mach flight payload deployment, including the benefit of the performance data, the company CEO heralded the DIU’s award, noting that the financing will help them move their successful demonstrations into real-world high-Mach platforms.

“This program is about moving high-Mach capability out of the lab and into an operationally relevant environment,” Piplica said.
