UB II Submarine is a boat accessible salt water dive site, located in Zeebrugge, Belgium. The maximum depth is 91-100ft/28-30m.

Location needs to be updated One report places it near the port of Ostende

from PM; The submarine is reportedly a Type UB II U-boat, a smaller class of submarine that typically operated in coastal waters. Just 88 feet long, the submarines had a crew of 23, carried six torpedoes, and were armed with a 88-millimeter deck gun. Thirty Type UB II subs were built. And not all were accounted for at the end of the war.

ABC News claims the submarine suffered extensive damage to its bow and that it "may have struck a mine." This sounds remarkably similar to the fate of the German Type UB II submarine UB-20, which, on July 28, 1917, reportedly struck a mine off the coast of Zeebrugge, Belgium during diving trials. UB-20 was lost with all hands. The submarine just discovered off the coast of Belgium had a full crew onboard when it went down.

The 93 German U-boats stationed in Belgian ports downed more than 2,500 ships but were also a target themselves, with 70 of them lost at sea, killing 1,200 sailors.

It was not yet clear which of the 11 known U-Boats had been found.

Belgium’s North Sea minister said he would investigate whether the wreck could be recognised as a heritage site.

The use of submarines in World War One to disrupt British trade routes in the English Channel and the North Sea was a key part of Germany’s military tactics.
