NASA is taking a modest but meaningful step toward making hypersonic flight testing more routine, awarding two contracts aimed at closing one of the biggest gaps in hypersonic development: the ability of conduct affordable, repeatable flight testing.
The agency announced it has selected study proposals from SpaceWorks Enterprises and Stratolaunch as part of its Hypersonic Technology Project. The six-month awards total $1.7 million and focus on how existing vehicles could be adapted to support higher-cadence hypersonic flight tests in the future.
Rather than pushing new experimental aircraft concepts, NASA is targeting a practical problem. Hypersonic research still relies heavily on wind tunnels and short-duration ground tests, which cannot fully replicate the heat, pressure, and airflow seen in real flight. Actual flight testing remains rare, expensive, and slow, creating a bottleneck that has limited progress for decades.
NASA now wants to ease that barrier. The agency’s focus is on “airbreathing” hypersonic vehicles, which use atmospheric oxygen rather than relying on rockets. Airbreathing designs promise longer endurance and reusability, but they are also harder to test, researchers say. Sustained hypersonic flight exposes vehicles to extreme thermal and structural loads that are difficult to model without real-world data.
The two studies aim to explore how commercially developed platforms might help bridge the gap between laboratory testing and full-scale flight programs. SpaceWorks will examine research using its X-60 platform, while Stratolaunch will focus on its Talon-A hypersonic test vehicle, which is designed to be air-launched from the company’s massive carrier aircraft.
NASA officials say the goal is not to field an operational vehicle, but to define what kind of flight-test infrastructure would make hypersonic development more predictable and affordable. That includes assessing cost, schedules, and how frequently test flights could realistically occur.
In practical terms, the awards signal that NASA is looking beyond one-off demonstration flights. Instead, the agency wants repeatable access to hypersonic flight conditions, similar to how subsonic and supersonic aircraft testing became more routine over time.
The work could also feed into a future NASA initiative known as Making Advancements in Commercial Hypersonics, or MACH. While still conceptual, MACH would focus on supporting commercial hypersonic development by helping industry overcome testing and infrastructure hurdles rather than designing government-owned aircraft.
The dollar amounts attached to the current awards are relatively small by aerospace standards, but the intent is clear. NASA is positioning itself as an enabler, working with industry to lower barriers that have kept hypersonic flight largely confined to military and experimental programs.
