The Sikorsky UH-60 Black Hawk is one of the most ubiquitous and iconic military helicopters, filling multiple roles for the US military, including air assault, general support, medevac, command and control, and special operations support.

The aircraft involved in the January 29 crash was flying with the call sign PAT25 and had three occupants, according to the Aviation Safety Network, a public database of aviation accidents.

More than 5,000 Black Hawks have been built since production began in the mid-1970s.
