HMS Otus (S18)

HMS "Otus" (S18) was a Royal Navy "Oberon"-class submarine. Built in 1962 at Scotts Yard in Greenock, Scotland, the sub's trials were conducted in Scottish waters, mainly Loch Long and Loch Fyne. Her pennant number (S18) was carried in white paint on the ship's conning tower fin, however this was removed in 1964 as a discontinued practice.

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.

HMS "Otus" was decommissioned in the early 1990s and resided at Pound's scrapyard in Portsmouth for several years [http://virtualglobetrotting.com/map/16174/] . She was later 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 [http://www.hms-otus.com/englishpage/indexenglish.php] .
