SM UB-10
1915 Type UB I submarine
SM UB-10 was a German Type UB I submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I.
UB-10 was ordered in October 1914 and was laid down at the AG Weser shipyard in Bremen in November. UB-10 was a little under 28 metres (92 ft) in length and displaced between 127 and 141 t (125 and 139 long tons), depending on whether surfaced or submerged. She carried two torpedoes for her two bow torpedo tubes and was also armed with a deck-mounted machine gun. UB-10 was broken into sections and shipped by rail to Antwerp for reassembly. She was launched in February 1915 and commissioned as SM UB-10 in March. The U-boat was the first of her class to commence operations when she entered service on 27 March 1915.
UB-10 was the first boat assigned to the Flanders Flotilla, the unit in which she spent her entire career. Her first two commanders were Otto Steinbrinck and Reinhold Saltzwedel, fifth and eleventh, respectively, among the top-scoring German submarine commanders of the war. UB-10 was credited with sinking 37 ships, about two-thirds of them British fishing vessels. The first ship sunk, the neutral Dutch steamer Katwijk, provoked outrage in the Netherlands and helped turn Dutch public opinion against Germany.

Why this record matters
The phrase “1915 Type UB I submarine” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 7, 2026. The linked authority identifier is Q7391618. Authority coordinates are 51.350, 3.200. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1914 and 1915.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
