U-Hawk Autonomous Black Hawk Status and Claimed Specs

Is the U-Hawk Real? Where the Program Stands

The Sikorsky U-Hawk is a physical prototype built by modifying an existing UH-60L Black Hawk helicopter into an uncrewed aircraft system (UAS).

Developed under the formal designation S-70UAS U-Hawk, the aircraft was unveiled publicly in October 2025 at the Association of the United States Army (AUSA) annual exposition. Lockheed Martin and its subsidiary Sikorsky stated that their rapid-prototyping unit, Sikorsky Innovations, brought the conversion from initial concept to a physical airframe in 10 months.

No source reports that the U-Hawk has flown as of October 15, 2026. In October 2025, Sikorsky Advanced Programs representative Ramsey Bentley told Defense One that first flight was targeted for the second quarter of 2026. That timeline slipped without a maiden flight taking place.

In an October 2026 Sikorsky-sponsored feature in The War Zone, Sikorsky business development director Jason Wrigley said Sikorsky plans to fly the U-Hawk later in 2026. Lockheed Martin's product page says the program is targeting first flight in 2026. The same sponsored feature says the U-Hawk is in Sikorsky's innovations hangar in Bridgeport, Connecticut, for final work.

No source names a U-Hawk customer, order or program of record. Sikorsky developed the prototype using internal corporate research and development funding rather than an active military contract. Breaking Defense reported that Sikorsky bought the baseline UH-60L back from the U.S. Army, which is divesting that model. The War Zone reported that Sikorsky had discussed logistics interest from the U.S. Army and U.S. Marine Corps.

What Sikorsky Changed on the Black Hawk

The U-Hawk conversion replaces the UH-60L's entire cockpit section with a clamshell cargo nose. Sikorsky removed the pilots, crew seats, crew chief stations, and internal components. In their place, Sikorsky installed actuated clamshell doors alongside an integrated loading ramp. This modification allows forward loading while retaining side-door cargo loading.

Sikorsky and Lockheed Martin say the forward ramp and the extra usable cabin space allow oversized loads up to the same maximum gross weight as the UH-60L.

To fly the helicopter without human pilots, Sikorsky installed a third-generation fly-by-wire system connected to its proprietary MATRIX autonomy architecture. As reported by Armada International, ground operators manage the aircraft using a tablet interface. A single button on the tablet commands the clamshell doors to open and deploys the ramp, and the system reverses that sequence before flight.

Sikorsky told Defense One it kept the UH-60L's transmissions, engines and rotor blades. According to Lockheed Martin, the U-Hawk has 95% commonality with the UH-60 fleet. Lockheed Martin also says the uncrewed design reduces operating and maintenance costs.

Verified vs Claimed: U-Hawk Figures

No U-Hawk flight has been reported, so every published U-Hawk performance figure is a Sikorsky or Lockheed Martin claim rather than a flight-test result.

Published U-Hawk cargo figures disagree in two places. Lockheed Martin marketing literature claims the aircraft provides 25% more cargo space than a standard Black Hawk, while Shephard reported that Sikorsky executives cited a 20% increase. Similarly, early press reports from Breaking Defense listed internal capacity as three Joint Modular Intermodal Containers (JMIC), whereas Lockheed Martin's press release stated the cabin holds up to four containers.

How MATRIX Flies It

Sikorsky's MATRIX autonomy software is designed to fly the U-Hawk. Lockheed Martin says the operator enters mission goals on a tablet, and MATRIX generates a flight plan using cameras, sensors and algorithms. MATRIX forms the core of the Defense Advanced Research Projects Agency (DARPA) Aircrew Labor In-Cockpit Automation System (ALIAS) program. DARPA describes ALIAS as an automation architecture for existing crewed aircraft.

Sikorsky flew MATRIX on an optionally piloted Black Hawk, which keeps its cockpit, before it built the U-Hawk. According to DARPA, a UH-60A Black Hawk retrofitted with MATRIX flew with no one aboard for 30 minutes on February 5, 2022, at Fort Campbell, Kentucky. DARPA says a second uninhabited flight followed on February 7, and Lockheed Martin gives the aircraft's tail number as N60-OPV.

Lockheed Martin's account of the mission says the pilots stepped out first. The aircraft then ran its preflight checklist, started its engines, took off, flew through a simulated cityscape and landed on its own. In March 2026, Sikorsky delivered an experimental UH-60MX equipped with MATRIX to the U.S. Army Combat Capabilities Development Command (DEVCOM) for military evaluation.

Sikorsky claims that MATRIX has logged more than 1,000 flight hours across 500 tests and demonstrations and is integrated on over 20 platforms. Lockheed Martin's product page says the U-Hawk can fly solo, in groups of U-Hawks, or alongside piloted Black Hawks.

U-Hawk vs the Optionally Piloted Black Hawk

The U-Hawk differs from the optionally piloted Black Hawk (OPV) that Sikorsky flew without crew in 2022. The OPV Black Hawk is an existing UH-60 that retains its full cockpit and pilot seats. Lockheed Martin says the OPV can be flown with or without crew.

In Lockheed Martin's account of the February 2022 Fort Campbell mission, the pilots re-boarded afterward and switched the aircraft back to piloted mode.

By contrast, Sikorsky removed the U-Hawk's cockpit section and crew stations entirely. The War Zone reports that the U-Hawk uses a different hardware backend for MATRIX and a revised fly-by-wire system. Sikorsky said the OPV's off-the-shelf components met human-rated aircraft standards, which the U-Hawk does not currently have to meet.

Igor Cherepinsky, director of Sikorsky Innovations, stated that the vehicle management computers developed for the conversion cost tens of thousands of dollars, far below the cost of a human-rated system.

Missions Sikorsky Describes

Sikorsky's Ramsey Bentley told Breaking Defense that Sikorsky sees the U-Hawk "being used across the Army for contested logistics mission support".

Sikorsky states that the internal cargo cabin can accommodate up to four standard military intermodal containers, or roll-on wheeled vehicles such as the HDT Hunter Wolf 6x6 uncrewed ground vehicle. Sikorsky claims example internal loads include one HIMARS pod of six rockets or two Naval Strike Missiles.

Beyond cargo, Sikorsky says the U-Hawk can deploy sensor or munition launched effects from quivers secured to the cabin. Lockheed Martin's product page calls this a new Quiver launching system for massed launched effects. Sikorsky's Ramsey Bentley told The War Zone the quiver holds 24 to 50 small or medium launched effects, while Breaking Defense reported 40 to 50.

What Is Not Published

Several U-Hawk program and performance figures are unpublished. Sikorsky has not disclosed the unit purchase cost for a newly converted aircraft, nor the price to convert an existing customer-owned airframe. Cherepinsky's figure of tens of thousands of dollars covers only the vehicle management computers.

Sikorsky has also not published the U-Hawk's speed, service ceiling, empty weight or hover endurance.

Sikorsky has not published a production schedule or a targeted conversion rate, and no source describes a U-Hawk production line. For readers tracking military drone companies, the next U-Hawk milestone to watch is its first flight. Breaking Defense calls the U-Hawk "a large Group 5 drone", but Lockheed Martin's release and product page do not place it in a UAS size group.
