Type 93 was a class of U-boats built during World War I by the Kaiserliche Marine.

Contents

Type 93 U-boats carried 16 torpedoes and had various arrangements of deck guns. As with the type 81 and 87, some had only one 8.8 cm (3.5 in) SK L/30 deck gun while others had a single 10.5 cm (4.1 in) SK L/45 gun and some were initially equipped with both. In 1917 some of the boats were refitted with a single 10.5 cm gun and 220 rounds.

These boats carried a crew of 39 and had excellent seagoing abilities with a cruising range of around 9,000 nautical miles (17,000 km; 10,000 mi). Many arrangements from the Type 81, 87 and 93 were also seen on World War II Type IX U-boats when their design work took place 20 years later.

Compared to the previous type 87, the 93s were 5.75 metres (18 ft 10 in) longer, while the pressure hull was 5.98 m (19 ft 7 in) longer. [3] They were 1.2 knots (2.2 km/h; 1.4 mph) faster on the surface, and unchanged at 8.6 knots (15.9 km/h; 9.9 mph) submerged. Range decreased 2,360 nmi (4,370 km; 2,720 mi) at 8 knots (15 km/h; 9.2 mph), to 9,020 nautical miles. They still carried 16 torpedoes with four bow and two stern tubes. Crew size was increased by 3 to 39.

Compared to the following type Large MS, the 93s were 11.95 m (39 ft 2 in)shorter, and 610 tonnes (600 long tons) lighter. [4] Their range was 980 nmi shorter, and speed was .2 knots (0.37 km/h; 0.23 mph) slower on the surface but .5 knots (0.93 km/h; 0.58 mph) faster submerged. The Large MS was intended for the deepest waters and the increased size made it more comfortable and very seaworthy.

Type 93 boats were responsible for sinking 3.201% of all allied shipping sunk during the war, taking a total of 412,419 combined tons. They also damaged 71,202 combined tons.

List of Type 93 submarines

There were 24 Type 93 submarines commissioned into the Kaiserliche Marine.

By the end of World War I, 375 U-boats of 33 separate classes belonging to 7 general types had been commissioned. More boats were finished after the war and either destroyed or awarded to victorious nations.

SM U-90 was a Type U-87 U-boat of the Imperial German Navy during World War I. Its commander Walter Remy made regular stops at remote island North Rona for provisions such as fresh mutton. On 15 May 1918, U-90 shelled the Hirta wireless station in St Kilda, Scotland. On 31 May 1918, U-90 torpedoed and sank USS President Lincoln, a former Hamburg America Line steamer that had been seized by the United States for troop transportation. From the U.S. Navy crew that abandoned the sinking vessel, U-90 captured Lieutenant Edouard Izac, eventually taking him to Germany. Izac later escaped German captivity and reported to the US Navy about German submarine movements.

SM <i>UC-1</i>

SM UC-1 was a German Type UC I minelayer submarine or U-boat in the German Imperial Navy during World War I. The U-boat had been ordered by November 1914 and was launched on 26 April 1915. She was commissioned into the German Imperial Navy on 5 July 1915 as SM UC-1. Mines laid by UC-1 in her 80 patrols were credited with sinking 41 ships. UC-1 disappeared after 18 July 1917. UC-1 was sunk on 24 July 1917 by F2B Felixstowe flying boat. Standard practice was to fly along the U boat and drop 2 250lb bombs astride it, hoping to cause leaks and give time for a destroyer to collect the submariners and sink it. On this occasion, by fluke, one bomb went through the conning tower and blew the base out of UC1. MFG Mill was awarded the DFC for this but he refused to wear it because of the total loss of life <london Gazette> <MFG Mill Diaries>

Mines laid by UC-14 in her 38 patrols were credited with sinking 16 ships, one of which was the Italian pre-dreadnought battleship Regina Margherita, which at 13,427 tonnes displacement was one of the largest ships sunk by U-boats during the war. UC-14 was mined and sunk on 3 October 1917.
