During the COVID-19 lockdown many residents are hearing sounds they may never have noticed before or have not heard as they were at their place of work. This is especially true for people living in the close vicinity of the naval base. Devonport Naval Base is the largest base in Western Europe, covering 650 acres across almost five miles. The nuclear sirens are tested every Monday morning at 11.30am. Nearby residents and businesses will be used to the wailing sound, like the sirens heard during WW2. But often the noise travels further and can be heard in parts of Cornwall – especially of late, as things have been so quiet. The reason the sirens were installed around the site is to provide a warning to all personnel on site that an off-site nuclear emergency has been declared. Although they are to alert staff in the naval base to take emergency action, members of the public around the site will be able to hear them.
