After more than 15 years, the largest naval base in Western Europe is once again opening its doors to the public.
The Royal Navy and Babcock have announced open days for July this year, 2025.
On Friday, 25 July, the navy base will be open to the public.
A family only open day will be held on Thursday, 24 July.

Public open days were previously scrapped by the Ministry of Defence over security concerns on the public being within the vicinity of the nuclear facility.
Local events company PL1 Events Limited will be managing the HMNB Devonport open days.
Further information on how you can secure tickets will soon follow.
