The Aircrew Labor In-Cockpit Automation System (ALIAS) program completed a first-ever flight of a UH-60A Black Hawk helicopter without anyone onboard. 

Sikorsky, a Lockheed Martin company, completed 30 minutes of uninhabited flight with the optionally piloted vehicle (OPV) over the U.S. Army installation at Fort Campbell, Kentucky, on Feb. 5, 2022. 

Funded by DARPA’s Aircrew Labor In-Cockpit Automation System (ALIAS) program, a UH-60A Black Hawk helicopter retrofitted with Sikorsky’s MATRIX autonomy technologies flew without anyone onboard for the first time in February 2022, over the U.S. Army installation at Fort Campbell, Ky.

Additional flights in October showed how existing and future piloted utility helicopters could one day fly complex missions in reduced crew or autonomous mode. This would give commanders and aviators greater flexibility in how and when aircraft and pilots are used, especially in limited visibility or contested environments.
