SIERRA VISTA, Ariz - US authorities took possession of an additional high-tech surveillance drone on Tuesday to overfly the rugged Arizona borderlands to look for drug smugglers and illegal immigrants crossing from Mexico.
The Predator-B drone is based at the National Air Security Operations Center in Sierra Vista, a few miles north of the Mexico border in southeast Arizona, the US Customs and Border Protection agency said.
The addition brings CBP's fleet of surveillance drones along the nearly 2,000-mile southwest border with Mexico to six. Four are based at the Arizona center, and two more overfly the border from Corpus Christi, Texas.
