A $43 million Department of Defense contract awarded to AeroVironment in May 2026 will put a software-steered radar antenna aboard high-altitude drones, giving the Pentagon its first airborne system designed to track multiple hypersonic test vehicles at the same time. The deal pairs the company’s PANTHER phased-array antenna with its SkyRange airborne telemetry platforms, a combination meant to replace aging ground-based tracking stations that were never built for weapons traveling at Mach 5 or faster.
The contract lands at a moment when the Defense Department is accelerating flight tests of several hypersonic programs, including the Long-Range Hypersonic Weapon (LRHW) for the Army and Navy and the Hypersonic Attack Cruise Missile (HACM) for the Air Force. Each of those programs needs range infrastructure that can collect precise flight data in real time. If the ground sensors watching those tests cannot keep up, engineers lose the measurements they need to refine the weapons.
What the contract covers
AeroVironment, the Arlington, Virginia-based defense drone and sensor company, announced the award through a Business Wire release. The core task is integrating the PANTHER Phased Array Antenna onto SkyRange platforms so the combined system can perform hypersonic telemetry, meaning it will capture real-time speed, trajectory, and performance data from test shots in flight.
PANTHER is an all-digital antenna. Instead of physically rotating a dish to follow a target, it steers its radar beams electronically through software. That distinction is critical: a mechanical antenna must reposition to track each object one at a time, while a digital array can jump between multiple targets in microseconds. For a test range that needs to monitor several hypersonic glide vehicles or boost vehicles launched in quick succession, that speed difference is the gap between useful data and missed measurements.
AeroVironment has been developing SkyRange as an alternative to the fixed ground instrumentation that traditional test ranges depend on. Those ranges rely on chains of radars and telemetry receivers spread across hundreds of miles of desert or open ocean. A single drone flying at high altitude can look down on a test corridor and cover geometry that would otherwise require dozens of ground stations. Pair that altitude advantage with a digitally steered antenna, and the system can hold track on more than one fast mover without losing lock on any of them.
Because PANTHER is software-defined, its behavior can be updated through code rather than hardware swaps. In principle, range operators could adjust beam patterns, revisit times, and data-collection modes as hypersonic test profiles evolve, all without grounding the aircraft for a major refit. That modularity aligns with the Pentagon’s broader push toward open-architecture sensors across its test and operational fleets.
The ground-station problem
The United States built its primary test ranges, including the Pacific Missile Range Facility and the Reagan Test Site at Kwajalein Atoll, during an era when intercontinental ballistic missiles followed predictable arcs and cruise missiles flew at subsonic speeds. Hypersonic glide vehicles break that model. They fly at extreme speeds along unpredictable, maneuvering trajectories that can skip along the upper atmosphere, making it difficult for fixed ground sensors to maintain continuous coverage.
The Government Accountability Office has flagged test-range modernization as a concern in multiple reports on hypersonic programs, noting that schedule slips in weapons development are sometimes compounded by gaps in range instrumentation. Moving tracking sensors into the air does not solve every problem, but it addresses one of the most stubborn: line-of-sight limitations. A ground radar sitting at sea level loses track of a low-flying or maneuvering vehicle once it dips below the radar horizon. An airborne node at 50,000 feet or higher has a vastly wider field of view.
Where MIDAS fits in
Defense Department records list a separate effort called the Millimeter-Wave Digital Arrays program, known by the acronym MIDAS. That program reflects a broader institutional bet on software-defined, scalable sensor arrays operating at millimeter-wave frequencies, the same part of the electromagnetic spectrum where high-resolution tracking data is easiest to collect.
MIDAS and PANTHER are not the same program, but they share a design philosophy: replace analog, mechanically steered hardware with digital arrays whose capabilities grow through software updates rather than physical rebuilds. Available records do not specify whether MIDAS feeds technology directly into PANTHER or whether the two run on parallel tracks with separate funding. That distinction matters. If PANTHER draws on common digital beamforming hardware or software toolkits developed under MIDAS, advances in one program could propagate quickly to the other. If not, each effort may be solving similar engineering problems independently.
What is still unknown
The public record leaves significant gaps. No released contract documents specify how many simultaneous targets a PANTHER-equipped SkyRange node can track, at what range, or at what data rate. The difference between tracking two hypersonic vehicles and tracking a dozen is enormous, and the Pentagon has not published performance benchmarks that would let outside analysts evaluate the system’s real capacity.
The integration timeline is similarly unclear. The $43 million covers development and integration, but neither AeroVironment nor the Defense Department has said when the first PANTHER-equipped platform will fly an operational telemetry mission. Antenna integration on an airborne platform typically requires extensive flight qualification, electromagnetic compatibility testing, and software safety certification, a process that can stretch across multiple test seasons.
Cost and scale remain opaque as well. The contract does not reveal the unit cost of each PANTHER array, the price of modifying each SkyRange airframe, or how large the eventual fleet will be. A handful of highly capable nodes might cover a single test corridor but fall short if the Pentagon wants to run simultaneous tests at multiple ranges or track longer trajectories arcing over the Pacific.
No independent test-and-evaluation office has published results on PANTHER’s airborne performance, and no Government Accountability Office review of hypersonic test infrastructure in the current cycle references this specific integration. The evidence base, for now, rests on one contract award and one program-level reference.
Why execution speed will decide the impact
The underlying technology concept is well established. Digital phased arrays have proven their value in ground-based air defense radars, shipborne combat systems like Aegis, and satellite communications. Extending that logic to airborne telemetry platforms is consistent with where the defense industry has been heading for years. The question is not whether the physics works but whether AeroVironment can move from integration and lab testing to repeatable, real-world data collection over live hypersonic shots on a timeline that matches the Pentagon’s accelerating test calendar.
The United States is not the only country pushing hypersonic development. China has conducted more hypersonic flight tests than any other nation over the past decade, according to assessments from the Congressional Research Service, and Russia has fielded the Avangard hypersonic glide vehicle. Keeping pace requires not just building the weapons but building the test infrastructure to refine them quickly. A modernized airborne range that can handle dense, fast-moving target sets would shorten the feedback loop between a test shot and the engineering data needed to improve the next one.
Until flight schedules, verified performance metrics, and independent evaluations enter the public record, the PANTHER-on-SkyRange effort is best understood as a concrete and well-funded step toward that goal, not yet proof that the goal has been reached.
