SM UB-42
SM UB-42 was a Type UB II submarine or U-boat for the German Imperial Navy (German: Kaiserliche Marine) during World War I. UB-42 operated in the Mediterranean and the Black Seas during the war. She was broken up at Malta in 1920.
UB-42 was ordered in July 1915 and was laid down at the AG Weser shipyard in Bremen in September. UB-42 was 36.90 m (121 ft 1 in) in length and displaced between 270 and 305 tonnes (266 and 300 long tons), depending on whether surfaced or submerged. She was equipped to carry a complement of four torpedoes for her two bow torpedo tubes and had an 5 cm (1.97 in) deck gun. As part of a group of six submarines selected for Mediterranean service, UB-42 was broken into railcar sized components and shipped to Pola where she was assembled, launched and commissioned in March 1916.
In 21 patrols during the war, UB-42 sank eleven ships of 16,047 gross register tons (GRT), captured one 97 GRT vessel as prize, and damaged HMS Veronica a British Acacia-class sloop. In October 1916, UB-42 delivered five Georgians who had gold to help finance a Georgian independence movement. After the surrender of the Ottoman Empire in late October 1918, UB-42 fled to Sevastopol, where she was surrendered in November. UB-42 was taken to Malta, where she was broken up in 1920.
The German UB II design improved upon the design of the UB I boats, which had been ordered in September 1914. In service, the UB I boats were found to be too small and too slow. A major problem was that, because they had a single propeller shaft/engine combo, if either component failed, the U-boat became almost totally disabled. To rectify this flaw, the UB II boats featured twin propeller shafts and twin engines (one shaft for each engine), which also increased the U-boat's top speed. The new design also included more powerful batteries, larger torpedo tubes, and a deck gun. As a UB II boat, U-47 could also carry twice the torpedo load of her UB I counterparts, and nearly ten times as much fuel. To contain all of these changes the hull was larger, and the surface and submerged displacement was more than double that of the UB I boats.
The German Imperial Navy ordered UB-42 from AG Weser of Bremen on 31 July 1915 as one of a series of six UB II boats (numbered from UB-42 to UB-47). UB-42 was 36.90 metres (121 ft 1 in) long and 4.37 metres (14 ft 4 in) abeam. She had a single hull with saddle tanks and had a draught of 3.75 metres (12 ft 4 in) when surfaced. She displaced 305 tonnes (300 long tons) while submerged but only 272 tonnes (268 long tons) on the surface.
The submarine was equipped with twin Daimler diesel engines and twin electric motors—for surfaced and submerged running, respectively—that drove one propeller shaft. UB-42 had a surface speed of up to 9.06 knots (16.78 km/h; 10.43 mph) and could go as fast as 5.71 knots (10.57 km/h; 6.57 mph) while underwater. The U-boat could carry up to 28 tonnes (28 long tons) of diesel fuel, giving her a range of 7,030 nautical miles (13,020 km; 8,090 mi) at 5 knots (9.3 km/h; 5.8 mph). Her electric motors and batteries provided a range of 45 nautical miles (83 km; 52 mi) at 4 knots (7.4 km/h; 4.6 mph) while submerged.
UB-42 was equipped with two 50-centimeter (19.7 in) bow torpedo tubes and could carry four torpedoes. The U-boat was also armed with one 8.8 cm (3.5 in) Uk L/30 deck gun.
UB-42 was laid down on 3 September 1915. As one of six U-boats selected for service in the Mediterranean while under construction, UB-42 was broken into railcar-sized components and shipped overland to the Austro-Hungarian port of Pola. Shipyard workers from Weser assembled the boat and her five sisters at Pola, where she was launched on 4 March 1916.
