SM UB-10
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. That sinking was also the impetus behind a renewed effort to avoid attacking neutral ships by U-boats. In a 13-day span in July and August 1915, UB-10 sank 23 ships, and by herself accounted for nearly all of the tonnage sunk by the Flanders Flotilla in the latter month. She was also responsible for sinking the British destroyer HMS Lassoo in August 1916. UB-10 had two close calls with British submarines near the Schouwen Bank off Zeebrugge in 1916 and 1917, but survived both.
By 1918, UB-10 had been converted into a minelayer by the replacement of her torpedo tubes with four mine chutes. UB-10 was seriously damaged in a British air raid on Flanders in July 1918, and was decommissioned in September 1918 in a worn out condition. She was not deemed seaworthy to sail to Germany when the bases in Flanders were being evacuated by the Germans in October 1918 and was scuttled off Zeebrugge in early October.
After the German Army's rapid advance along the North Sea coast in the earliest stages of World War I, the German Imperial Navy found itself without suitable submarines that could be operated in the narrow and shallow seas off Flanders. Project 34, a design effort begun in mid-August 1914, produced the Type UB I design: a small submarine that could be shipped by rail to a port of operations and quickly assembled. Constrained by railroad size limitations, the UB I design called for a boat about 28 metres (92 ft) long and displacing about 125 t (123 long tons) with two torpedo tubes.
UB-10 was part of the initial allotment of seven submarines—numbered UB-9 to UB-15—ordered on 15 October from AG Weser of Bremen, just shy of two months after planning for the class began. UB-10 was laid down by Weser in Bremen on 7 November. As built, UB-10 was 27.88 metres (91 ft 6 in) long, 3.15 metres (10 ft 4 in) abeam, and had a draft of 3.03 metres (9 ft 11 in). She had a single 60-metric-horsepower (44 kW) Körting 4-cylinder diesel engine for surface travel, and a single 120-metric-horsepower (88 kW) Siemens-Schuckert double-acting electric motor for underwater travel, both attached to a single propeller shaft. Her top speeds were 7.45 knots (13.80 km/h; 8.57 mph), surfaced, and 6.24 knots (11.56 km/h; 7.18 mph), submerged. At more moderate speeds, she could sail up to 1,500 nautical miles (2,800 km; 1,700 mi) on the surface before refueling, and up to 45 nautical miles (83 km; 52 mi) submerged before recharging her batteries. Like all boats of the class, UB-10 was rated to a diving depth of 50 meters (160 ft), and could completely submerge in 33 seconds.
UB-10 was armed with two 45-centimeter (17.7 in) torpedoes in two bow torpedo tubes. She was also outfitted for a single 8-millimeter (0.31 in) machine gun on deck. UB-10's standard complement consisted of one officer and thirteen enlisted men.
After work on UB-10 was complete at the Weser yard, she was readied for rail shipment. The process of shipping a UB I boat involved breaking the submarine down into what was essentially a knock down kit. Each boat was broken into approximately fifteen pieces and loaded onto eight railway flatcars. In early 1915, the sections of UB-10 were shipped to Antwerp for assembly in what was typically a two- to three-week process. After UB-10 was assembled and launched on 20 February, she was loaded on a barge and taken through canals to Bruges where she underwent trials.
