Branch members commemorate HMS Sidon (P259)

On Tuesday 16 June 2026, 7 members of Portland Branch RNA gathered with members of the local Submariners Association to remember those that perished in 1955 on HMS Sidon.

Launched in 1944 and built by Cammell Laird, HMS Sidon served with the Royal Navy in the post‑war years. On 16 June 1955, while alongside in Portland Harbour, an experimental torpedo exploded on board, sinking the submarine and taking the lives of 13 submariners.  The boat was later raised but too badly damaged to return to service, and she was finally laid to rest as a target in 1957.

Today, the Portland community and the Royal Naval Association continue to honour the men of Sidon and ensure their sacrifice is never forgotten.

We will remember them.
