SM U 9 was a petroleum-electric submarine of the German Imperial Navy that was used in the First World War .
Technical specifications
The two-hull high seas boat was 57.38 m long, 6.00 m wide, had a draft of 3.13 m and a displacement of 493 tons above and 611 tons under water. The diameter of the pressure hull was 3.65 m. This allowed it to descend to a maximum of 50 m in 50–90 seconds.
The drive took place over water with 1000 HP strong petroleum motors and under water with electric motors (1160 HP). This enabled speeds of 14.2 knots (above water) and 8.1 knots (under water).
The six torpedoes carried along could be fired through two bow and two stern tubes.
history
U 9 was first boot in its class ( U 10 , U 11 and U 12 given) on 15 July 1908 in order and at the Imperial Shipyard in Gdansk on keel down. The launch took place on February 22, 1910, the delivery on April 18, 1910. On July 16, 1914, the team of U 9 managed - for the first time ever - to reload torpedoes during a dive .
On September 22, 1914 U 9 sank the three British armored cruisers HMS Aboukir , HMS Hogue and HMS Cressy one after the other under the command of Kapitänleutnant Otto Weddigen about 50 km north of Hoek van Holland . Around 1,500 people lost their lives and around 800 were saved. On the next patrol on October 15, the boat was able to sink the British protected cruiser HMS Hawke off Aberdeen . After Weddigen and its crew, the boat itself received an award, as it was allowed to carry an iron cross on the tower. Except for U 9 , only the small cruiser SMS Emden received this honor during World War I.
On January 12, 1915, the previous First Watch Officer, Johannes Spieß, became Weddigen's successor. Under his command, U 9 moved to the Baltic Sea and was converted into a mine-layer there. On August 16, 1915, SM U 9 sank the British steamer Serbino by torpedo fire near the Baltic Sea island of Worms . On November 5, 1915, a Russian minesweeper was sunk. This was the fifth warship success of U 9 . Spieß commanded U 9 until April 19, 1916. Then the boat was used as a school boat in Kiel until the end of the war . On November 26, 1918 the boat was delivered to Great Britain and in 1919 it was scrapped in Morecambe , Lancashire .
U 9 undertook a total of seven enemy voyages and sank five warships with 44,173 tons and 13 merchant ships with 8,636 GRT. No other boat sank more warships during the First World War.
