HMS Untamed was a Royal Navy U-class submarine built by Vickers-Armstrongs, High Walker.

[2][3] Untamed was subsequently salvaged and renamed HMS Vitality, another unique name, and lasted until 1946 when she was scrapped.

Shemara located Untamed with sonar and heard the sounds of her engines being run and tanks being blown.

There was no outward sign of damage and it was not until after Untamed was salvaged on 5 July 1943 that it was found that she had been flooded through a sluice valve.

The Sandbank War Memorial at Hunters Quay is in part dedicated to the crew of Untamed[5] who were buried in Dunoon Cemetery.
