U-10, Submarine museum in Wilhelmshaven, Germany.

The U-10 (S189) is a diesel-electric Type 205 submarine of the German Navy, built by Howaldtswerke-Deutsche Werft in Kiel and launched on 5 June 1967. It now rests outdoors on grey supports as a museum ship at the Deutsches Marinemuseum in Wilhelmshaven, its dark grey hull marked "S189" in white on the conning tower. Near the bow sits a circular array of open torpedo tubes, and torpedo-shaped objects lie on the ground beside the hull.

Howaldtswerke-Deutsche Werft in Kiel built U-10 as a Type 205 diesel-electric submarine. It was launched on 5 June 1967 and commissioned into the German Navy on 28 November 1967. After decommissioning on 6 February 1993, it became a museum ship at the Deutsches Marinemuseum in Wilhelmshaven.

The narrow passageways and low ceilings show how confined daily life was for the crew aboard. Walking through the galley and sleeping quarters makes the limited personal space at sea feel real.

The visit involves climbing steep ladders and passing through narrow hatches, so sure footing is needed. Anyone uncomfortable in tight spaces can ask staff beforehand if a shorter tour is available.

The control room still holds the original instruments, including the periscope once used to spot ships. Looking through the lens now reveals the harbour instead of open water.
