U.S. Army Awards Northrop $325M Contract for RangeHawk Hypersonic Missile Testing Drone.

Northrop Grumman has secured a $325.5 million U.S. Army contract to develop the RangeHawk high-altitude uncrewed aircraft, a specialized airborne platform designed to track and collect data from hypersonic and long-range weapon tests, according to a contract announcement released on May 14, 2026. The program addresses a critical weakness in U.S. hypersonic weapons development by giving the Army a persistent airborne sensor platform capable of following missiles traveling at extreme speeds beyond the effective coverage of fixed or ship-based test infrastructure.

RangeHawk is intended to carry telemetry, tracking, and data-relay payloads that can remain close to a missile’s flight path for extended periods, improving the quality and reliability of test data during high-speed trials. The capability supports faster refinement of next-generation strike weapons and reflects the growing importance of flexible airborne test networks as the United States accelerates hypersonic modernization and long-range precision strike development.

RangeHawk is derived from the RQ-4 Global Hawk family, whose baseline characteristics explain why the airframe was selected. The U.S. Air Force lists the RQ-4 as a high-altitude, long-endurance remotely piloted aircraft with a Rolls-Royce F137-RR-100 turbofan producing 7,600 pounds of thrust, a 130.9-foot wingspan, a 47.6-foot length, a maximum takeoff weight of 32,250 pounds, a 3,000-pound payload, a 310-knot speed, a 12,300-nautical-mile range, more than 34 hours of endurance, and a 60,000-foot operating ceiling. The same fact sheet lists its armament as “none,” which is important for interpreting the Army contract correctly: RangeHawk’s military value is not weapons carriage but persistent airborne instrumentation.

The technical “armament” of RangeHawk is therefore its mission payload. Instead of missiles, bombs, or guided rockets, the aircraft is expected to carry telemetry receivers, phased-array antennas, electro-optical and infrared tracking sensors, timing references, mission processors, data-storage equipment, and secure communications links. A related May 2026 AeroVironment award for the PANTHER, or Phased Array Next-gen Telemetry Hypersonic Emitter Receiver, shows the type of equipment being inserted into the broader SkyRange architecture: an all-digital phased-array antenna intended to support hypersonic telemetry and track multiple targets simultaneously from a rapidly deployable airborne node. This is directly relevant to boost-glide tests, where engineers need speed, trajectory, thermal, vibration, navigation, and separation-event data before the vehicle is lost, impacted, or recovered.

The universal payload architecture is the most significant element of the new Army award because it addresses integration speed rather than only aircraft availability. A conventional sensor installation can require aircraft-specific mounts, wiring, power conversion, cooling changes, software interfaces, electromagnetic compatibility work, and flight safety certification. A modular architecture should allow the Army and the Test Resource Management Center to change telemetry receivers, antennas, processors, or optical sensors as test requirements evolve, without redesigning the aircraft for every missile program. For U.S. hypersonic testing, that flexibility matters because Dark Eagle, Conventional Prompt Strike, air-breathing hypersonic missiles, rocket-boosted test vehicles, and thermal-protection experiments may all require different viewing angles, frequencies, bandwidths, and data formats.

Operationally, RangeHawk changes the geometry and tempo of missile trials. The Pentagon has historically used instrumented ships for parts of long-range missile testing, but moving those ships to the correct ocean area can take weeks or months and requires crews, range scheduling, and sea-state coordination. TRMC Director George Rumford said SkyRange allowed support for hypersonic tests over the Atlantic and Pacific only days apart, and C4ISRNET reported that SkyRange supported 10 hypersonic flight tests in fiscal 2023, with expectations of more than 15 in fiscal 2024. That difference is not administrative; it determines how often engineers can expose designs to real flight conditions and how quickly failures can be diagnosed.

The Army's need is tied to the maturity of Dark Eagle, formally designated on April 24, 2025, as the Long-Range Hypersonic Weapon. A Congressional Research Service report carried by USNI News states that Dark Eagle has a reported range of 1,725 miles and is intended to give the Army a conventional precision-strike capability against time-sensitive and heavily defended targets in contested environments. The missile uses the Common Hypersonic Glide Body, while the missile component serves as the common two-stage booster for both the Army LRHW and the Navy Conventional Prompt Strike weapon. On March 31, 2026, Army Contracting Command–Redstone Arsenal awarded a $2.7 billion production contract supporting Dark Eagle, and Reuters reported that Leidos said the contract moves hypersonic weapons from prototype development into production.

This is why the United States needs RangeHawk even though it does not add a firing unit to the order of battle. Hypersonic weapons are sensitive to thermal protection, guidance accuracy, booster-glide body separation, communications blackout, structural loads, and terminal maneuver behavior; many of those variables cannot be fully validated in wind tunnels or digital models. A high-altitude uncrewed aircraft with long endurance can trail or bracket a test corridor, collect line-of-sight telemetry that might otherwise be masked by curvature or distance, and provide independent tracking data for post-flight reconstruction. The likely result is not automatic success for any individual missile program, but a better test cadence, fewer data gaps, and a lower probability that a costly flight ends without enough evidence to guide the next engineering decision.

For the Army, the broader implication is acquisition risk reduction. Dark Eagle and related Navy systems depend on a common industrial and technical base that includes Lockheed Martin, Northrop Grumman, Leidos subsidiary Dynetics, Sandia-derived glide-body work, booster integration, launchers, canisters, command vehicles, and test ranges. If range availability becomes a bottleneck, production contracts can outpace confidence in design maturity. RangeHawk is a comparatively indirect investment, but it targets that bottleneck: it turns retired or repurposed high-altitude aircraft into mobile range assets that can follow the geography of the test rather than forcing the test to conform to fixed infrastructure. For U.S. long-range fires modernization, that makes the aircraft a measurement system with strategic consequences, not a surveillance aircraft repainted for a secondary mission.
