This US Customs and Border Protection (US CBP) Black Hawk belongs to the largest federal law enforcement agency of the United States, the Department of Homeland Security. The UH-60A was based at Holloman and flew regularly its missions alongside the Mexican border. It was once delivered to the US Army as UH-60A 77-22718 but was converted to UH-60L by Sikorsky Aerospace Service at Chase Field, Beeville (TX) late 2010. The Mike was delivered to the Aviation Flight Test Directorate for trials in 2011 and redelivered to the US CBP mid-2011.
