Sikorsky Presents Unmanned S-70UAS U-Hawk at AUSA 2025

Sikorsky has transformed a UH-60L Black Hawk helicopter into the S-70UAS U-Hawk, an autonomous unmanned aircraft  that has 25% more cargo space than a typical Black Hawk.

Sikorsky replaced the cockpit section with actuated clamshell doors and ramp, and swapped conventional flight controls with a fly-by-wire system integrated with the MATRIX autonomy technology.

The S-70UAS U-Hawk aircraft on display at this week’s Association of the United States Army (AUSA 2025) exposition shows a larger cabin space to:

Accept longer cargo, such as missiles,

Drive on/off an uncrewed ground vehicle,

Roll-on/off supplies,

Launch swarms of reconnaissance or strike drones, and

Carry internal fuel tanks for increased range or extended time on station.

Said Rich Benton, Sikorsky vice president and general manager. “We developed this prototype from concept to reality in under a year, and the modifications made to transform this crewed Black Hawk into a multi-mission payload UAS can be replicated at scale quickly. The U-Hawk continues the Black Hawk legacy of being the world’s premier utility aircraft and opens the door to new capabilities as a UAS.”

Redesign and structural modification of the UH-60L aircraft into its uncrewed U-Hawk configuration is led by rapid prototyping group Sikorsky Innovations. First flight is expected in 2026.

Forward loading and additional useable cabin space of the U-Hawk aircraft now offers the flexibility to accommodate oversized loads up to the same maximum gross weight.

S-70UAS U-Hawk Features

Air-ground team — Drive on/off an uncrewed ground vehicle, such as the HDT Hunter Wolf 6x6 UGV.

Cargo — Transport up to four Joint Modular Intermodal Containers (vs. two today).

Missile transport — Carry a HIMARS pod of six rockets, or two Naval Strike Missiles.

Launched effects — Deploy launched effects carrying sensors/munitions from quivers secured to the cabin.

Endurance — Self-deploy over 1600nm or loiter for up to 14 hours without refueling.

Like a UH-60L aircraft, a U-Hawk variant retains the ability to load cargo from the side door, and externally lift 9,000 pounds (4,080 kg) using its cargo hook.

Remote Operators – not pilots – fly U-Hawks

A tablet gives an operator full command of the U-Hawk aircraft from start-up to shut down.

At the touch of a button, the two clamshell doors open and a ramp lowers to allow easy cargo loading or drive-on capability. To prepare for flight, the automated sequence is reversed.

Once loaded, an operator inputs mission goals via the tablet. The MATRIX autonomy system automatically generates a flight plan, relying on cameras, sensors and algorithms to help navigate the U-Hawk aircraft safely to its destination.
