Jeffrey Alcantara, from Los Angeles, Calif., the anti-terrorism officer assigned to the Arleigh Burke-class guided-missile destroyer USS Barry (DDG 52), stands ballistic missile defense (BMD) officer watch in the ship’s combat information center during bi-lateral exercise Resilient Shield 2021.

As the U.S. Navy's largest forward-deployed fleet, U.S. 7th Fleet employs 50 to 70 ships and submarines across the western Pacific and Indian Oceans. U.S. 7th Fleet routinely operates and interacts with 35 maritime nations while conducting missions to preserve and protect a free and open Indo-Pacific region.
