100 Emergency Services and Military personnel are taking part in a security exercise at Portsmouth Naval Base.
Emergency services and the military are staging a routine security exercise at Portsmouth Naval Base on Sunday (July 3).
One hundred personnel from the Navy, Army, Ministry Defence Police and civilian police, fire and ambulance services will take part.
The exercise - between 6.30pm and 9.30pm - involves blank ammunition which is likely to be heard outside the base, particularly along Queen Street, The Hard and parts of Gosport. Emergency services will be using vehicle sirens within the base.
Naval Base Security Officer Simon Harfield said: "The exercise is part of routine security contingency planning and training and is not in response to any specific threat or any increase in the threat level.
"The aim of the exercise is to practice close multi-agency working, emergency service incident response and to test command and communications."
