The Trump administration is taking the unusual step of deploying a Navy warship off the waters of the U.S. as part of its broader crackdown on security and migration along the Mexico border.

USS Gravely is the fifty-seventh destroyer in its class and has served the Navy in various capacities over the years.

The Department of Defense described the move as a significant shift, giving the U.S. Navy a direct role in stopping threats before they reach American shores.
