Schnellboot S-103

The German Torpedo Schnellboot sunk on the last day of World War II killing 20 men. Location: Southern Little Belt, approx. 3 nautical miles southeast of Mommark (Als, Denmark). Depth: 33 meters (standing upright on the seabed). Coordinates (WGS 84): 54°53.97′ N, 10°07.18′ E

Due to large amounts of live explosives (depth charges) on and around the site anchoring and fishing are strictly prohibited within a 500-meter radius of the position.

The History: The Last Day of WWII
On May 4, 1945—the very day Germany signed its unconditional surrender—the German E-boat S 103 was ordered to sail from Svendborg to Flensburg to scout British troop advancements. Commanded by Oberleutnant Hans Wulf Heckel, the boat was carrying 32 people, including many non-crew evacuees. Around 3:00 PM, an Allied fighter-bomber spotted the vessel through a gap in the clouds. Despite a desperate half-hour struggle, S 103 was heavily struck by rockets and cannon fire, destroying its engines and defense systems. The ship sank just hours before the official ceasefire. Only 12 of the 32 people onboard survived, rescued by a local fisherman from Mommark.

The Wreck Condition
Discovered by sports divers in the 1970s and later surveyed by the Danish Navy, the S 103 is historically a “ghost wreck” that remained hidden for 31 years because it sat outside shipping lanes at 33 meters.

The Hull stands perfectly upright and intact on the seabed, showing very little damage from commercial trawlers.
Armament: The forward automatic cannon is missing, but the stern cannon remains completely intact.
The Wheelhouse: Very cramped, but historically featured the original aluminum engine telegraph just inside the door.
Hazards: Aside from some light fishing nets, the primary hazards are unexploded WWII depth charges lying on the deck and scattered next to the stern.

The Dive

6 Degree water temperature in 34m depth. The ship didn’t anchor and we didn’t touch the wreck or anything else during the dive.
