FST-J 71, the maritime component of the Japan-U.S. Joint Integrated Air and Missile Defense (Defensive) Exercise, provided computer-generated training to commands ashore and ships at sea, enabling combined forces to refine ballistic missile defense coordination in a complex operational environment. The exercise focused on strengthening command and control, decision making, and defensive responses while protecting sensitive capabilities.

“Fleet Synthetic Training allows our U.S. and Japanese teams to rehearse demanding scenarios and improve how we operate together,” said U.S. Navy Rear Adm. Eric Anduze, commander of Task Force (CTF) 70, “This training strengthens deterrence by ensuring our forces remain ready to defend the United States and Japan while maintaining security across the Indo-Pacific.”
