Work has just started demolishing the existing building. It will be replaced with a new factory complete with indoor firing range and staff facilities including restaurant and car park.
The new factory, which will manufacture small arms ammunition for the British troops, is one of three manufacturing sites that BAE Systems is committed to modernising to make them more highly automated and energy efficient.
The new build is scheduled to complete in May 2011.
Peter Millett, managing director for Shepherd Construction said: “During the build, the project will require specialist construction of the ammunition propellant storage facilities and production areas to incorporate explosive and bullet-proof design elements.”
