Stratolaunch released a new video documenting the completion of its second hypersonic flight and full recovery of its Talon-A2 autonomous vehicle, showing off the capabilities of this sleek reusable hypersonic aircraft. This successful follow-up mission, recently undertaken on March 24 of this year, follows in the wake of the Talon-A2 vehicle's initial first hypersonic flight and runway recovery back on Dec. 20, 2024. The Talon-A2 is an advanced air-launch plane lifted aloft by a gigantic dual-fuselage aircraft designed by Scaled Composites with a world-leading 385-foot (117 meters) wingspan and nicknamed "Roc." When positioned and deployed at altitude over 20,000 feet, the dart-shaped hypersonic marvel is dropped from Roc's center wing pylon before its Ursa Major Hadley rocket engine comes alive to propel it to Mach 5 and beyond. "With the data collected from this second flight, we are able to apply lessons learned to enhance the strength and performance of the Talon-A vehicles," said Dr. Zachary Krevor, President and CEO of Stratolaunch in a statement. "While the team needs to complete its data review of flight two, the first flight review confirmed the robustness of the Talon-A design while demonstrating the ability to meet the full range of performance capabilities desired by our customers."

Both December's and March's flights packed payloads and Department of Defense experiments. These thrilling missions mark America's first return to reusable hypersonic flight testing since that manned X-15 program ended in 1968. Stratolaunch is a revolutionary air-launch enterprise founded back in 2011 by the late Microsoft co-founder Paul Allen. Cerberus Capital Management formally purchased Stratolaunch back in 2018, transferring its headquarters from Seattle, Washington to Mohave Air and Space Port in California with an emphasis on evolving and operating world-class hypersonic aerospace craft. A second launch platform is currently being developed using a Boeing 747-400 once owned by the now-defunct Virgin Orbit and now renamed "Spirit of Mojave." This updated aircraft will provide a more convenient, compact carrier than the mighty "Roc" for future flights and testing of the next generation of Stratolaunch vehicle dubbed the Talon-A3, which should be ready to fly sometime in late 2025. Stratoluanch previously tested the single-use prototype Talon-A1 on March 9, 2024, which was not equipped with landing gear and executed a perfect ocean splashdown.

This US Company Just Successfully Tested a Reusable Hypersonic Rocket Plane
Stephen Clark, Ars Technica May 7, 2025 5:00 PM Stratolaunch completed two flights of its autonomous Talon-A2 rocket plane earlier this year, as the US aims to gain ground in its race for hypersonic supremacy with China. Stratolaunch has finally found a use for the world's largest airplane. Twice in the past five months, the company launched a hypersonic vehicle over the Pacific Ocean, accelerated it to more than five times the speed of sound, and autonomously landed at Vandenberg Space Force Base in California. Stratolaunch used the same vehicle for both flights. This is the first time anyone in the United States has flown a reusable hypersonic rocket plane since the last flight of the X-15, the iconic rocket-powered aircraft that pushed the envelope of high-altitude, high-speed flight 60 years ago. Stratolaunch announced the results of its two most recent test flights Monday. In December and again in March, Stratolaunch's Talon-A2 rocket plane launched from the belly of an enormous carrier aircraft over the Pacific Ocean and flew several hundred miles to Vandenberg, a military spaceport about 140 miles northwest of Los Angeles. There, the aircraft touched down on a concrete runway that NASA and the Air Force once considered for Space Shuttle landings. Mach 5 or Bust Zachary Krevor, president and CEO of Stratolaunch, spoke with Ars on Monday afternoon. He said the Talon test vehicle advances the capability lost with the retirement of the X-15 by flying autonomously. Like the Talon-A, the X-15 released from a carrier jet and ignited a rocket engine to soar into the uppermost layers of the atmosphere. But the X-15 had a pilot in command, while the Talon-A flies on autopilot. 'Why the autonomous flight matters is because hypersonic systems are now pushing the envelope in terms of maneuvering capability, maneuvering beyond what can be done by the human body,' Krevor said. 'Therefore, being able to perform flights with an autonomous, reusable, hypersonic testbed ensures that these flights are exploring the full envelope of capability that represents what's occurring in hypersonic system development today.' Stratolaunch's Talon-A is a little smaller than a school bus, or about half the size of the X-15. Stratolaunch's Talon-A2 vehicle lands at Vandenberg Space Force Base, California. Photograph: Stratolaunch 'Demonstrating the reuse of fully recoverable hypersonic test vehicles is an important milestone for MACH-TB,' said George Rumford, director of the Test Resource Management Center, in a statement. 'Lessons learned from this test campaign will help us reduce vehicle turnaround time from months down to weeks.' Krevor said Talon-A carried multiple experiments on each mission but did not offer any details about the nature of the payloads, citing proprietary reasons and customer agreements. 'We cannot disclose the nature of those payloads, other than to say typical materials, instrumentation, sensors, etc.,' he said. 'The customers were thrilled with their ability to recover the payloads shortly after landing.' Stratolaunch completed the first powered flight of a Talon-A vehicle last year, when the rocket plane launched over the Pacific Ocean and fired its liquid-fueled Hadley engine—produced by Ursa Major—for about 200 seconds. The Talon-A1 vehicle accelerated to just shy of hypersonic speed, then fell into the sea as planned and was not recovered. That set the stage for Talon-A2's first flight in December. Military officials previously stated they set up the MACH-TB program to enable more frequent flight testing of hypersonic weapon technologies, including communication, navigation, guidance, sensors, and seekers. Stratolaunch aims for monthly flights of the Talon-A rocket plane by the end of the year and eventually wants to ramp up to weekly flights. 'These flights are setting the stage now to increase the cadence of hypersonic flight testing in this country,' Krevor said. 'The ability to have a fully reusable hypersonic flight architecture enables a very high cadence of flight along with a lot of responsiveness. The DoD can call Stratolaunch if there's a priority program, and we can have a hypersonic flight next week, assuming the readiness of all the other technologies and payloads.' Pentagon officials in 2022 set a goal of growing US capacity for hypersonic testing from 12 to 50 flight tests per year. Krevor believes Stratolaunch will play a key part in making that happen. Catching Up So, why is hypersonic flight testing important? The Pentagon seeks to close what it views as a technological gap with China, which US officials acknowledge has become the world's leader in hypersonic missile development. Hypersonic weapons are more difficult than conventional missiles for aerial defense systems to detect, track, and destroy. Unlike ballistic missiles, hypersonic weapons ride at the top of the atmosphere, enhancing their maneuverability and ability to evade interceptors. Hypersonic flight is an unforgiving environment. Temperatures outside the Talon-A vehicle can reach up to 2,000° Fahrenheit (1,100° Celsius) as the plane plows through air molecules, Krevor said. He declined to disclose the duration, top speed, and maximum altitude of the December and March test flights but said the rocket plane performed a series of 'high-G' maneuvers on the journey from its drop location to Vandenberg.

Photograph: Stratolaunch/Brandon Lim Engineers know less about the conditions of the hypersonic flight regime (in excess of Mach 5) than they do about lower-speed supersonic flight or spaceflight. The only vehicles that regularly fly at hypersonic speeds are missiles, rockets, and spacecraft reentering the atmosphere. They spend just a short time flying in the hypersonic environment as they transition to and from space. There are two things you should know about hypersonic missiles. First, rockets have flown at hypersonic speeds since 1949, so when officials talk about hypersonic missiles, they are referring to vehicles that operate in the hypersonic flight environment, instead of just transiting through it. Second, hypersonic vehicles come in a couple of variations. One is a glide vehicle, which is accelerated by a conventional rocket to hypersonic speed, then steers itself toward its destination or target using aerodynamic forces. The other is a cruiser that can sustain itself in hypersonic flight using exotic propulsion, such as scramjet engines. The military recently tested an intermediate-range hypersonic weapon, known by the Army as Dark Eagle and by the Navy as Conventional Prompt Strike, using the glide vehicle architecture. The Army's version could be operational later this year. Meanwhile, the Air Force is working on a scramjet-powered hypersonic cruise missile, but it likely won't be ready for combat for a few more years. Not only must a vehicle operate in the extreme hypersonic flight regime, but any operational hypersonic weapon must be 'affordable' and 'manufactured at high rate,' two Pentagon officials wrote in prepared testimony to the House Armed Services Committee last year. 'Our goal is to enable the nation's industrial base to manufacture hypersonic systems at a cost comparable to traditional weapon systems and at the capacity necessary to achieve a decisive advantage for the warfighter on the battlefield,' the officials wrote. A test launch of the US Navy's Conventional Prompt Strike weapon occurred April 25 at Cape Canaveral, Florida. Photograph: Kyle Ryan/ US Defense Department The Pentagon has spent about $12 billion on hypersonic weapons development and testing since 2018. None of the weapons are operational yet. All of these initiatives aim to match China's hypersonic capabilities. US officials believe China's first hypersonic weapon, using the glide vehicle architecture, became operational in 2019. Russia's government claimed it deployed a hypersonic weapon named Avangard the same year. China began testing a scramjet-powered hypersonic cruise missile in 2018. Paving the Way The Pentagon's emphasis on hypersonic weapons is relatively new. After the X-15's final flight in 1968, the government lacked any major hypersonic flight test programs for several decades. NASA flew the autonomous X-43 test vehicle to hypersonic speed two times in 2004, and the Air Force demonstrated an air-breathing scramjet engine at Mach 5.1 with the X-51 Waverider aircraft in 2013. While some of the X-43 and X-51 test flights failed, they provided early-stage data on hypersonic propulsion systems that could power high-speed aircraft and missiles. But these were expensive government-led programs. Together, they cost nearly $1 billion in 2025 dollars, with only a handful of flight tests to show for it. The military now wants to lean heavier on commercial industry. Since its founding 14 years ago, Stratolaunch has pivoted its mission from the airborne launch of satellites to hypersonic testing. Stratolaunch was one of the first US launch companies to capitalize on the US military's growing interest in hypersonic technology. Rocket Lab now flies a suborbital version of its Electron satellite launcher to carry hypersonic experiments. ABL Space Systems, now known as Long Wall, last year announced it was walking away from the space launch business entirely to focus on hypersonic testing. The military's MACH-TB program offers a lucrative source of revenue for these rocket companies. Through its subsidiary Dynetics, the defense contractor Leidos manages the first phase of the MACH-TB program, which aims to develop and demonstrate commercial hypersonic test vehicles. In January, the Pentagon awarded a nearly $1.5 billion contract to Kratos Defense & Security Solutions for MACH-TB 2.0, which will transition the program from flight demonstrations to hypersonic test services. Stratolaunch and Rocket Lab will launch hypersonic experiments under MACH-TB 2.0, while a range of government, commercial, and academic institutions will develop the materials and technologies to be tested. Quilty Space, a space industry research firm, estimates the market for hypersonic testing is worth between $6 billion and $7 billion. This illustration from the Government Accountability Office compares the trajectory of a ballistic missile with those of a hypersonic glide vehicle and a hypersonic cruise missile. Illustration: GAO It has taken a long time for Stratolaunch to find its footing. At one time, Stratolaunch partnered with SpaceX to use an air-launched version of the Falcon 9 rocket to deliver satellites to orbit. When that partnership fell through, Stratolaunch worked with Orbital Sciences, now part of Northrop Grumman, to design an air-launched rocket. Stratolaunch's founder, Microsoft billionaire Paul Allen, died in 2018, putting the company's future in doubt. Stratolaunch flew its huge carrier aircraft, named Roc , for the first time in April 2019 but ceased operations the following month. Cerberus Capital Management, a private equity firm, purchased Stratolaunch from Allen's heirs later that year and redirected the company's mission from space launch to hypersonic flight testing. Through it all, Stratolaunch continued flying Roc , a twin-fuselage airplane with a wingspan of 385 feet (117 meters). For a time, it appeared Roc might share a fate with Howard Hughes' 'Spruce Goose' flying boat, which held the record as the airplane with the widest wingspan, until Roc (officially designated the Scaled Composites Model 351) took off for the first time in 2019. The Spruce Goose flew just once after its business prospects faded in the aftermath of World War II. Now, the Pentagon's hunger for hypersonic weapons seems likely to feed Stratolaunch's coffers for some time to come. The company is building a second rocket plane, Talon-A3, scheduled to enter service in the fourth quarter of this year. It will launch from a Boeing 747 carrier aircraft that Stratolaunch acquired from Virgin Orbit after it went bankrupt in 2023. The longer range of the 747 will allow Stratolaunch to stage hypersonic tests from other locations beyond the West Coast. This story originally appeared on Ars Technica.

Pentagon's Hypersonic Drone Hits Mach 5 in Record-Breaking Tests
A California-based startup pulled off two hypersonic flights of its reusable aircraft, which became the first fully autonomous drone to reach Mach 5 speeds. Stratolaunch's Talon-A2 completed a series of test flights for the Pentagon's Missile Defense Agency, part of a hypersonic testbed program that echoes Cold War-era efforts like the X-15, which retired in 1968. The hypersonic vehicle exceeded Mach 5 speeds during the tests that took place in December 2024 and March 2025, Stratolaunch revealed this week. 'We've now demonstrated hypersonic speed, added the complexity of a full runway landing with prompt payload recovery, and proven reusability,' Zachary Krevor, president and CEO of Stratolaunch, said in a statement. The Talon-A prototype is an autonomous, reusable aircraft capable of flying at least five times the speed of sound. During its test flights, Roc—the largest airplane ever built—released the vehicle over the Pacific Ocean. Stratolaunch's Roc took off with Talon-A1 tucked in its belly before the hypersonic vehicle conducted its own flight and landed at Vandenberg Space Force Base. When it was founded in 2011, Stratolaunch intended to use Roc to launch Orbital ATK's Pegasus XL rocket into space. Following its founder Paul Allen's death in 2018, the company switched gears to focusing on developing, deploying, and flying hypersonic vehicles instead. In December 2021, Stratolaunch announced a contract with the Pentagon's Missile Defense Agency to provide a testbed for developing defense strategies against hypersonic threats. In March 2024, Talon-A1 launched for its first powered test flight, reaching hypersonic speeds that didn't quite make it to Mach 5. Unlike Talon-A1, Stratolaunch's latest prototype, Talon-A2 is fully reusable. The company is developing future versions of the Talon-A, which will be rocket-powered and capable of carrying customizable payloads at hypersonic speeds. Stratolaunch is also working on a larger hypersonic vehicle, dubbed Talon-Z, and a spaceplane nicknamed Black Ice, that would carry payloads—and possibly passengers—to Earth orbit. Talon-A2's recent flights mark the first hypersonic flights since the X-15 program conducted by the U.S. Air Force and NASA. The X-15 hypersonic aircraft were air-launched from a B-52 aircraft, and flew a total of 199 times over the span of 10 years. The program ended in the late 1960s due to a lack of funding and a shift of focus toward orbital missions. The Department of Defense has shown a renewed interest in hypersonic vehicles as other nations like China and Russia are working on developing their own. The U.S. has never operated a reusable hypersonic vehicle, a capability that could significantly reduce costs. 'Demonstrating the reuse of fully recoverable hypersonic test vehicles is an important milestone for MACH-TB,' George Rumford, director of the Department of Defense Test Resource Management Center, said in a statement. 'Lessons learned from this test campaign will help us reduce vehicle turnaround time from months down to weeks.'

Stratolaunch goes hypersonic with reusable Talon-A vehicle
Two hypersonic flight tests were completed mere months apart using the same autonomous vehicle, a milestone for the U.S. as it jockeys with other world powers for speedy, maneuverable weapons. Why it matters: The Talon-A flights handled by Stratolaunch contribute to the Pentagon's Multi-Service Advanced Capability Hypersonic Test Bed program (MACH-TB). The U.S. has lacked a recoverable hypersonic aircraft for decades, since the X-15 was ditched. What they're saying: "We've now demonstrated hypersonic speed, added the complexity of a full runway landing with prompt payload recovery, and proven reusability," Stratolaunch CEO Zachary Krevor said in an announcement. In both instances, Talon-A launched from a larger aircraft known as Roc and landed at Vandenberg Space Force Base, California. What we're hearing: There are additional chefs in the kitchen. Leidos, for example, oversees MACH-TB. Northrop Grumman tested its Advanced Hypersonic Technology Inertial Measurement Unit aboard Talon-A. The company said it collected "hours of critical ground and flight data." Ursa Major's Hadley engine sustained the speeds. CEO Dan Jablonsky in March told Axios the company is pouring money into "hypersonics, hypersonics and hypersonics."

Stratolaunch took its uncrewed Talon-A2 prototype to hypersonic speeds for the first time this past December, then repeated the feat in March, the company announced on Monday (May 5). "We've now demonstrated hypersonic speed, added the complexity of a full runway landing with prompt payload recovery and proven reusability," Stratolaunch President and CEO Zachary Krevor said in a statement on Monday. "Both flights were great achievements for our country, our company and our partners." Stratolaunch's Roc carrier plane — seen here with the dart-shaped Talon-A2 hypersonic vehicle still attached — has a wingspan of 385 feet (117 meters). | Credit: Stratolaunch/Brandon Lim Microsoft co-founder Paul Allen established Stratolaunch in 2011, with the goal of air-launching satellites from a giant carrier plane called Roc, which has a wingspan of 385 feet (117 meters). That vision changed after Allen's 2018 death, however; the company is now using Roc as a platform to test hypersonic technology. Hypersonic vehicles are highly maneuverable craft capable of flying at least five times the speed of sound. Their combination of speed and agility make them much more difficult to track and intercept than traditional ballistic missiles. The United States, China and other countries view hypersonic tech as vital for national security, and are therefore developing and testing such gear at an ever-increasing pace. Stratolaunch, Roc and the winged, rocket-powered Talon-2A are part of this evolving picture, as the two newly announced test flights show. They were both conducted for the U.S. military's Test Resource Management Center Multi-Service Advanced Capability Hypersonic Test Bed (MACH-TB) program, under a partnership with the Virginia-based company Leidos. On both occasions, Roc lifted off from California and dropped Talon-2A over the Pacific Ocean. The hypersonic vehicle then powered its way to a landing at Vandenberg Space Force Base, on California's Central Coast. "These flights were a huge success for our program and for the nation," Scott Wilson, MACH-TB program manager, said in the same statement. "The data collected from the experiments flown on the initial Talon-A flight has now been analyzed and the results are extremely positive," he added. "The opportunity for technology testing at a high rate is highly valuable as we push the pace of hypersonic testing. The MACH-TB program is pleased with the multiple flight successes while looking forward to future flight tests with Stratolaunch."

But we do know at least one piece of tech that Talon toted — Northop Grumman's Advanced Hypersonic Technology Inertial Measurement Unit, which is designed to help hypersonic vehicles navigate. "Survivability of the navigation unit, also known as a hemispherical resonator gyroscope, is a major accomplishment due to the harsh environment hypersonic speed presents and the intense forces experienced as the technology operates within Earth's atmospheric boundary," Northop Grumman representatives said in a different statement. "This technology collected hours of critical ground and flight data, pivotal for future development."

HASTE has flown three times to date, on each occasion from the Mid-Atlantic Regional Spaceport in Virginia. And the cadence could pick up in the near future: Both the U.S. and U.K. militaries recently picked Rocket Lab as a potential partner for their hypersonic-tech programs.
