U.S. Expands SkyRange Program With $92.2M AEVEX Deal to Accelerate Hypersonic Weapons Testing.

The United States is expanding its SkyRange program to accelerate hypersonic weapons testing across domestic and Pacific corridors, with AEVEX Corp. selected under a three-year contract worth up to $92.2 million to support airborne tracking and test operations. By using high-altitude Range Hawk drones instead of relying mainly on fixed ranges and scarce tracking ships, the program is designed to increase test frequency and give U.S. developers more flexibility to evaluate hypersonic systems under operationally relevant conditions.

The Range Hawk aircraft will provide airborne instrumentation, communications, flight operations, and integration support needed to track high-speed weapons over long distances. Expanding this mobile test infrastructure could shorten development cycles for future hypersonic missiles while strengthening the U.S. ability to validate long-range strike capabilities across the Indo-Pacific.

SkyRange is a U.S. Department of Defense airborne test-range concept that converts high-altitude RQ-4 Global Hawk unmanned aircraft into Range Hawk test assets equipped with upward-looking sensors, telemetry receivers, and communications systems. By moving instrumentation into the air, SkyRange is designed to track hypersonic vehicles across long flight corridors and reduce dependence on fixed ground ranges and specialized tracking ships, giving the Pentagon more flexibility to schedule and support complex U.S. hypersonic weapons tests.

AEVEX announced the contract on September 16, 2026, and it supports the U.S. Test Resource Management Center under the Training and Readiness Accelerator II, or TReX II, Other Transaction Authority. The investment addresses a critical Pentagon hypersonic program bottleneck: obtaining enough instrumented flight opportunities to develop long-range weapons for increasingly demanding Pacific operating requirements.

Under the contract, AEVEX will provide airborne-range integration and engineering, flight operations, airborne telemetry relay and resilient communications, payload and mission-system integration, distributed range networking, instrumentation, and mission-data support. Together, these capabilities are intended to create a mobile test architecture able to follow hypersonic vehicles across very large geographic areas while collecting the telemetry and tracking data required to evaluate propulsion, aerodynamics, thermal protection, guidance, navigation, and control. The central advantage is mobility: traditional hypersonic tests depend heavily on fixed ground sensors and specialized tracking ships positioned along a planned trajectory, meaning test planners must coordinate scarce assets around a missile flight path, while Range Hawk drones can carry instrumentation aboard long-endurance aircraft that reposition along the corridor and configure sensor coverage around the mission.

The Range Hawk is based on former RQ-4 Global Hawk high-altitude unmanned aerial vehicles converted from their original intelligence, surveillance, and reconnaissance role into airborne test-range assets. Equipped with upward-looking sensors, telemetry receivers, communications equipment, and other instrumentation, the aircraft are designed to observe hypersonic vehicles from altitude while remaining airborne for extended periods across long test corridors. The RQ-4 airframe is well suited to this role because its high operating altitude, long endurance, and extensive range allow it to remain beneath or near extended missile trajectories for many hours, which is particularly valuable for Pacific missile testing where flight paths can span enormous distances and where permanent instrumentation is geographically limited.

This airborne approach could offer important advantages over traditional tracking ships and fixed ranges. Ships remain useful because they can carry large sensor suites and support maritime testing, but they require transit time, crews, suitable positioning, and favorable scheduling before a test can proceed. A Range Hawk drone can fly directly to an assigned sensor station, shift position when a trajectory changes, and potentially support successive missions without the same maritime deployment burden. Fixed ground sensors, meanwhile, provide high-quality coverage where they are installed, but extending that coverage across new or very long trajectories can require substantial infrastructure investment, while a network of Range Hawk aircraft can reposition existing instrumentation to meet each test's needs.

The concept does not eliminate the need for ships or ground stations. Hypersonic flight testing requires multiple sensor types, redundant collection points, and different geometries to reconstruct a vehicle’s trajectory and performance accurately, and fixed and maritime assets can provide capabilities that airborne systems cannot fully replace. SkyRange instead adds another layer to the test architecture, giving the Pentagon more options for building instrumented corridors without depending exclusively on the availability of traditional range assets.

AEVEX’s work on resilient communications and airborne telemetry relay matters because losing data during a hypersonic test can sharply reduce the value of an expensive flight. A missile traveling at several times the speed of sound moves rapidly between sensor coverage zones, while propulsion, structural, guidance, and thermal events can occur within seconds, making continuous data capture essential. Distributed networking is intended to connect airborne and terrestrial range elements so mission data can be relayed through multiple paths rather than depending on a single collection point, increasing the likelihood that engineers retain the information needed to diagnose failures, validate models, and prepare the next flight configuration.

This matters because the challenge facing U.S. hypersonic weapons development is not limited to designing missiles capable of sustained hypersonic flight. The Pentagon must also maintain enough launch opportunities, test vehicles, telemetry coverage, tracking sensors, data-processing capacity, and specialized personnel to repeatedly fly developmental systems and learn from each event. Test infrastructure can therefore become a pacing factor even when the missile itself is technically ready for another flight, and SkyRange addresses that problem from the instrumentation side by making it easier to assemble coverage around a mission rather than waiting for a narrow combination of available ships, fixed sensors, and range windows.

More flexible range availability can shorten the interval between identifying a technical issue, modifying a weapon, and returning it to flight testing. That is especially important for hypersonic systems because ground facilities and computer modeling cannot completely reproduce the aerodynamic heating, propulsion behavior, communications conditions, structural loads, and guidance challenges encountered during actual high-speed flight. The Test Resource Management Center has also pursued a higher hypersonic test cadence through initiatives such as the Multi-Service Advanced Capability Hypersonics Test Bed, or MACH-TB, which is intended to provide more opportunities for components and technologies to reach flight conditions, while SkyRange complements that effort by expanding the sensing and communications infrastructure needed to collect useful engineering data when those flights occur.

The Pacific dimension gives the AEVEX contract additional strategic significance. U.S. long-range strike development increasingly requires test corridors that can support weapons over distances relevant to operations across the Indo-Pacific, where geography places a premium on extended-range missiles, distributed sensing, and resilient communications. Repositionable airborne instrumentation lets test planners establish temporary sensor coverage across those distances without building permanent range infrastructure along every possible trajectory, while also allowing tests to be configured around the weapon's characteristics rather than the limitations of a fixed sensor network.

The contract also demonstrates how retired RQ-4 aircraft can be repurposed into specialized assets supporting U.S. hypersonic weapons development. The Global Hawk family was originally designed for persistent high-altitude surveillance, but the same endurance, altitude, payload capacity, and communications characteristics that supported intelligence missions can be adapted to carry test instrumentation over long distances. This reuse lets the Pentagon extract additional value from existing airframes while expanding a test enterprise that increasingly depends on mobile, distributed sensing rather than only conventional range infrastructure.

For the U.S. defense industrial base, the SkyRange program highlights how hypersonic development depends on a much broader ecosystem than missile manufacturers alone. Launch systems, telemetry networks, tracking sensors, communications links, test aircraft, modeling tools, targets, and data-processing systems all affect how quickly a weapon can move from engineering development to operational deployment. The up-to-$92.2 million AEVEX award therefore represents an investment in test capacity rather than simply another support contract, because it combines Range Hawk drones, airborne telemetry, resilient communications, distributed networking, and mission-data support into a system intended to make U.S. hypersonic flight testing less dependent on the availability and geography of traditional fixed ranges and tracking ships.

If the airborne approach delivers the intended flexibility, its most important effect will be more usable, data-rich flight tests. For the Pentagon hypersonic program, that could mean faster identification of technical problems, shorter redesign cycles, and more opportunities to validate long-range weapons under Pacific-scale conditions before they enter operational service.
