On May 15, 2026, the Department of Defense quietly posted a contract award worth $325,531,920 to Northrop Grumman for a prototype drone that does not carry weapons, does not conduct surveillance on enemy territory, and will never see combat. Its job is to fly high enough and long enough to watch America’s own hypersonic missiles scream across the sky at more than a mile per second, collecting the test data that ground-based radars increasingly cannot.
The program is called RangeHawk. According to the DoD contracts bulletin, the cost-plus-fixed-fee award funds a “high-altitude long-endurance airborne test resource” built around what the Pentagon calls a universal payload architecture, essentially a modular sensor bay that can be reconfigured for different missions. A separate $43 million contract, awarded to AeroVironment through the Test Resource Management Center, will equip the aircraft with phased-array antennas capable of electronically steering radar beams fast enough to maintain a lock on targets that change direction at extreme velocity.
Together, the two awards total roughly $368 million and represent the Pentagon’s most concrete investment yet in solving a problem defense officials have acknowledged for years: the nation’s test ranges were designed for subsonic and supersonic weapons, not for glide vehicles that skip along the upper atmosphere at Mach 5 and above.
Why ground radars are losing the picture
Traditional test ranges, like the sprawling facilities at White Sands Missile Range in New Mexico or the Pacific Missile Range Facility in Hawaii, rely on ground-based radars and downrange telemetry stations to track weapons in flight. That architecture works well when a missile follows a predictable ballistic arc at moderate speed. Hypersonic glide vehicles break the model. They fly lower and more erratically than ballistic reentry warheads, hugging the upper atmosphere while executing unpredictable lateral maneuvers. At shallow tracking angles, a ground radar’s beam must punch through hundreds of miles of dense atmosphere, degrading signal quality and sometimes losing the target entirely during critical phases of flight.
An airborne sensor solves the geometry. A drone orbiting at high altitude along a pre-positioned corridor can look down or across at a hypersonic vehicle from a much shorter, cleaner path. It does not need to match the missile’s speed. Instead, it needs endurance (to loiter for hours before and after a test window), altitude (to stay above weather and atmospheric distortion), and antennas fast enough to slew electronically rather than mechanically. That is precisely the combination RangeHawk appears designed to deliver.
What Northrop Grumman is actually building
The Pentagon has not released technical specifications for RangeHawk, including its maximum altitude, sensor range, data throughput, or flight endurance. The contract’s cost-plus-fixed-fee structure, in which the government reimburses allowable expenses and pays a fixed profit margin on top, signals that the design is still maturing. That format is standard for early-stage development work where final costs are hard to predict.
Northrop Grumman’s San Diego division, which received the award, is the same organization that produces the RQ-4 Global Hawk, the Air Force’s long-endurance surveillance drone that routinely operates above 55,000 feet for more than 30 hours at a stretch. While no official source has confirmed that RangeHawk shares Global Hawk’s airframe or subsystems, the contractor’s deep experience in high-altitude, long-endurance unmanned aircraft makes the pairing logical. The “universal payload architecture” language suggests the airframe is designed to swap sensor packages depending on the test event, a philosophy Northrop Grumman has applied to Global Hawk variants like the MQ-4C Triton used by the Navy.
AeroVironment’s phased-array antenna system adds the tracking muscle. According to a press release from the office of U.S. Senator John Hoeven, the antennas will convert aircraft into mobile sensor stations for tracking hypersonic test vehicles. Phased-array systems steer their beams electronically in microseconds, a necessity when the target covers a mile every second and can change course without warning. Hoeven’s statement refers to the broader effort as “SkyRange” and describes the equipped aircraft as “SkyRange aircraft,” suggesting RangeHawk is one platform within a larger airborne test infrastructure.
SkyRange vs. RangeHawk: untangling the names
The Pentagon’s contract bulletin uses only the name RangeHawk. Senator Hoeven’s office uses SkyRange. No single official document published to date defines the hierarchy between the two labels. The most defensible reading, based on available records, is that SkyRange is the overarching campaign to field airborne hypersonic test assets and RangeHawk is a specific unmanned platform within it. But until the Test Resource Management Center or another Pentagon office publishes a program overview that maps the relationship explicitly, that interpretation remains an informed inference rather than documented fact.
The hypersonic race driving the spending
The investment makes more sense against the backdrop of an accelerating global competition. The Congressional Research Service’s report R45811 catalogs active hypersonic programs in the United States, China, and Russia, noting that all three nations are pursuing both hypersonic glide vehicles and hypersonic cruise missiles. China has conducted multiple flight tests of its DF-ZF glide vehicle, and Russia has declared its Avangard glide vehicle operational. The United States, meanwhile, has pushed forward with programs like the Army’s Long-Range Hypersonic Weapon and the Navy’s Conventional Prompt Strike, both of which require extensive flight testing before they can be fielded with confidence.
Every one of those tests demands instrumentation that can capture high-fidelity data on speed, trajectory, thermal signatures, and maneuvering behavior. Without that data, engineers cannot validate designs, identify failure modes, or certify weapons for operational use. If the existing test infrastructure cannot keep up, the entire development pipeline slows down. That is the bottleneck RangeHawk is meant to break.
Open questions taxpayers should track
Several gaps in the public record deserve scrutiny as the program moves forward. First, no cost-benefit analysis or alternatives assessment has been released. The Pentagon may have considered upgrading manned test aircraft, expanding ground-based radar networks, or leaning more heavily on space-based sensors before committing $368 million to a new drone platform. Without that context, it is difficult to judge whether RangeHawk represents the most efficient path.
Second, cost growth is common in early-stage aerospace programs, particularly those integrating new sensor suites and software-defined payloads. The $325 million ceiling on the Northrop Grumman contract could rise as the prototype moves through design, fabrication, payload integration, and flight testing. Congress and the Government Accountability Office will need to monitor actual expenditures against that estimate.
Third, endurance and altitude figures, once disclosed, will determine whether a single RangeHawk can shadow a hypersonic vehicle through its full flight profile or only capture data during specific phases like boost, midcourse, or terminal descent. If coverage gaps remain, the Pentagon may need multiple drones airborne simultaneously, multiplying operational costs.
Finally, the program’s timeline is unclear. The contract bulletin does not specify a delivery date for the prototype or a target for first flight. Hypersonic weapon tests are already underway across multiple services, meaning every month of delay in fielding RangeHawk is a month of test flights conducted with less-than-ideal instrumentation.
What $368 million buys, and what it does not
The public record as of late May 2026 supports a narrow but significant conclusion: the Pentagon is spending hundreds of millions of dollars on unmanned aircraft and advanced antennas to close a testing gap that hypersonic weapons have forced open. RangeHawk will not chase missiles in the way a fighter jet chases a target. It will orbit, watch, and listen, turning raw sensor data into the engineering feedback that determines whether a weapon works or fails. That role is less dramatic than the speeds involved but no less critical. The United States cannot field reliable hypersonic weapons if it cannot accurately measure what those weapons do in flight. RangeHawk is a bet that the best way to see a Mach-5 missile clearly is to put the eyes in the sky rather than leave them on the ground.
