Beginning this week, the Navy is holding an annual anti-terrorism exercise that could mean extra traffic and delays around bases across Hampton Roads.
Dubbed Solid Curtain-Citadel Shield, the nationwide training is meant to help the service practice how it would respond to terrorist threats at home. The Coast Guard and local emergency responders also are taking part.
It'll start Tuesday and last through the end of the month, Navy officials said. They're telling people who live near or commute to bases to plan for delays and expect to see and hear extra activity, including loudspeaker announcements and sirens.
The exercise is not related to any specific threat, officials said. It's the Navy's biggest anti-terrorism training.
It will help to "build cohesion, test communications (and) response procedures, and identify any shortfalls," officials with Joint Expeditionary Base Little Creek-Fort Story said in a news release.
Yorktown Naval Weapons Station said it's planning to simulate an "active shooter" situation as part of the exercise Wednesday.
"While mitigations to alleviate traffic are in place, the potential for base-access delays exists," a base release said.
In years past, the exercise has occasionally caused significant delays.
