Things may look very real around the Portsmouth Naval Shipyard Thursday but it's actually just a drill.

The shipyard is conducting an active shooter drill Thursday between noon and 3 p.m. in the vicinity of Dry Dock #3, the closest dry dock to Kittery Foreside. The location makes it possible residents may see response activity and hear the shipyard-wide loud speaker announcements while the drill takes place.

The drill is part of Exercise Citadel Shield-Solid Curtain 2023 which takes place at all U.S. Navy facilities located in the continental United States. between Feb. 6 and Feb. 17.

"The exercise is designed to enhance the readiness of Navy security forces and ensure seamless
interoperability among the commands, other services and agency partners," public affairs specialist Jeremy Lambert said in a statement.

There will likely be similar activity visible on the last day of the drill.
