The reunion of the HMS Penelope Association will be held in Blackpool later this month.
Members of the association are inviting Blackpool residents to take part in a service to mark the 71st anniversary of the sinking of the ship, which was adopted by Blackpool.
Mike Bee, secretary of the association, said: “The wartime cruiser HMS Penelope was the adopted warship of Blackpool until she was sunk on February 18, 1944 with the loss of 417 of her crew.
“Attending the reunion weekend will be a number of survivors of the sinking, as well as others who served with her on previous occasions, as well as some who served in the more recent frigate Penelope, now sadly departed from the Royal Navy.”
A church service will be held at St John’s Church, St John’s Square, Blackpool, at noon on Sunday, February 22.
Mr Bee added: “The Mayor and Mayoress will be joining us, and we again invite the people of Blackpool to join with us to remember those who died.”
