The chief of naval operations is hosting the 22nd International Seapower Symposium from Wednesday through Friday in Newport. The event draws senior military representatives from more than 110 countries.
Two U.S. Navy ships, a fast transport and an amphibious transport dock ship, and a Coast Guard national security cutter are visiting Newport as part of the symposium. The ships are not open for public tours.
The Naval station asks that people not go to the gate to request access.
It says more than 100 cars were turned away at the gate when the stealthy and futuristic Zumwalt destroyer visited this month, causing traffic backups.
