Construction

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.

Royal Navy service

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

Otus attended the 1977 Silver Jubilee Fleet Review off Spithead when she was part of the Submarine Flotilla.[2]

In July 1987, a team of British, Commonwealth and international submariners took part in trials in Bjornafjorden, near Bergen, Norway, aboard Otus. They ran a series of progressively deeper escapes, starting at 30 metres (98 ft). At 90 metres (300 ft), individuals started to drop out. At the end of the trials two submariners reached a depth of 183 metres (600 ft). This set a new world record which to date has not been broken. Of the two record breakers, the first (the commander of the Submarine Escape Training Tower at HMS Dolphin) was a regular ascent under control. The second, a petty officer instructor from the Submarine Escape Training Tower suffered an emergency release having given the alarm signal whilst flooding up the chamber. It was considered safer and quicker to escape him rather than depressurise and drain down. Both escapees suffered no lasting effects and returned to normal service. Both received military honours of the British Empire in the following years for this act.

Otus was deployed to the Persian Gulf during the 1991 Gulf War under Operation Granby. On her return to Gosport, she was flying a Jolly Roger; the only indication that the submarine had been involved in deploying and recovering Special Air Service and Special Boat Service personnel.[3][4]

Decommissioning and museum

Otus was decommissioned in the early 1990s and resided at Pound's scrapyard in Portsmouth for several years. 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.[5]
