A security exercise will take place at BAE Systems in Barrow this weekend.
It will take place on Saturday, November 22, between 10am and noon.
BAE Systems said the exercise would be fully contained within the site boundary at the Devonshire Dock complex so there should be no interruption to the wider community.
It added people should not be alarmed and there would be no need to take any action.
There will be an increased emergency services presence in the area to assist with the exercise.
