Submarine HMS Otus (S18)

HMS Otus (S18) was a British Royal Navy Oberon class submarine. Built in 1962 at Scotts Yard in Greenock, Scotland.

The first commission of HMS Otus included large-scale missile trial exercises in the Atlantic Ocean and visits to the United States and Halifax, Canada.

HMSS Otus was decommissioned in the early 1990s and was purchased by a German entrepreneur, who moored her in the harbour of the town of Sassnitz on the island of Rügen in Germany to act as a floating naval museum.
