Sikorsky and DARPA have teamed up to build an autonomously piloted Black Hawk helicopter for dangerous resupply or casualty evacuation missions. Lockheed Martin, the parent company of Sikorsky, announced the tests of the system, writing:
Sikorsky, a Lockheed Martin company, and the Defense Advanced Research Projects Agency (DARPA) successfully demonstrated these autonomous mission scenarios to the U.S. Army in mid-October 2022.
Three demonstration flights totaling 2.4 hours were performed at Yuma Proving Ground in Arizona as part of the U.S. Army’s Project Convergence 2022 (PC22) Technology Gateway exercise.
“During PC22 Technology Gateway, we showed how the optionally piloted Black Hawk helicopter can be flown by human pilots, who then land the aircraft and simply flip a switch to activate flight with zero pilots,” said Igor Cherepinsky, Sikorsky Innovations director.
“With no humans on board, the aircraft flew at 100 knots, to deliver a large quantity of blood product, an external cargo load, and rescue a casualty.”
Sikorsky’s MATRIX™ technology is the enabling technology for optionally piloted flight, which includes the option for no pilots on board. MATRIX forms the core of DARPA’s ALIAS (Aircrew Labor In-cockpit Automation System) project, an ongoing collaboration between Sikorsky and DARPA since 2015.
Long endurance medical resupply
Loaded with 14 boxes containing 400 units (500 lbs./226 kg) of real and simulated blood rigged to the cabin floor, the aircraft flew 83 miles (133 km).
During the 50-minute flight, the aircraft descended as low as 200 feet (61 m) above ground level through valley terrain to mask its signature while maintaining 100 knots airspeed.

External cargo delivery and casualty evacuation (combined mission flight)
The Black Hawk aircraft lifted off with a 2,600 lbs. (1179 kg) external load attached to a 40-ft (12 m) sling suspended from the cargo hook
The aircraft flew at 100 knots for 30 minutes to the designated landing site.
On approach, Sikorsky demonstrated how a ground operator with a secure radio and tablet can take control of the autonomous aircraft. Ground control of the helicopter simulated a scenario in which a threat needed to be neutralized near the landing site.
The ground operator commanded the aircraft to release its sling load safely onto the ground, then directed the helicopter to land at a nearby site to evacuate a casualty.
A manikin on a litter was quickly loaded into the cabin, and the ground operator commanded the aircraft to fly to a field hospital.
During the flight, the BATDOK health status monitoring system relayed the manikin patient’s vitals to ground-based medical personnel via the helicopter’s communications system.

Optionally piloted
The Black Hawk aircraft flown for the autonomous demonstrations is optionally piloted — meaning the same aircraft can be flown by two pilots, one pilot, or no pilots, depending on the mission requirements.
Unlike other uninhabited aircraft that rely on a ground-based pilot to fly the aircraft, the MATRIX system gives full control to the aircraft’s flight computer, which compiles a flight plan based on high level goal inputs, such as destination location, distance, and topography.
