On 16 July 1914, the crew of U-9 reloaded her torpedo tubes while submerged, the first time any submarine had succeeded in doing so. See also: Action of 22 September 1914 Action of 22 September 1914 The boat's complement was 4 officers and 31 enlisted. When U-9 underwent a major refit in 1916, two mine-laying rails were added, which were later removed again. In 1915, an additional 5 cm (2.0 in) gun was fitted. Originally, the boat was equipped with a machine gun, which was augmented with a 3.7 cm (1.5 in) Hotchkiss gun when war broke out in 1914. The U-boat was armed with four 50 cm (20 in) torpedo tubes, two fitted in the bow and two in the stern, and carried 6 torpedoes.
These engines powered two shafts, each with a 1.45 m (4.8 ft) propeller, which gave the boat a top surface speed of 14.2 knots (26.3 km/h 16.3 mph), and 8.1 knots (15.0 km/h 9.3 mph) when submerged.

U-9 was fitted with two Körting 8-cylinder plus two Körting 6-cylinder two-stroke petrol engines with a total of 1,000 metric horsepower (735 kW 986 bhp) for use on the surface and two Siemens-Schuckert double-acting electric motors plus two electric motors with a total of 1,160 PS (853 kW 1,144 shp) for underwater use. The boat displaced 493 t (485 long tons) when surfaced and 611 t (601 long tons) when submerged. She had a draught of 3.13 m (10 ft 3 in) with a total height of 7.05 m (23 ft 2 in). The boat's beam was 6 m (19 ft 8 in) (o/a), while the pressure hull measured 3.65 m (12 ft 0 in). U-9 had an overall length of 57.38 m (188 ft 3 in), her pressure hull was 48 m (157 ft 6 in) long. She was launched on 22 February 1910 and commissioned on 18 April 1910. Her construction was ordered on 15 July 1908 and her keel was laid down by Kaiserliche Werft in Danzig. She was one of 329 submarines serving in the Imperial German Navy, and engaged in commerce raiding ( Handelskrieg) during World War I. four 45 cm (17.7 in) torpedo tubes (2 each bow and stern).2 × Körting 6-cylinder and 2 × Körting 8-cylinder two stroke paraffin motors with a total of 1,000 PS (740 kW 990 shp).Atom-U-Boote haben gegenüber den meist kleineren und kostengünstigeren U-Booten mit konventionellen Antrieben, wie etwa dem dieselelektrischen Antrieb, vor allem den Vorteil einer fast unbeschränkten Reichweite und der Tatsache, dass bei Atom-U-Booten die Dauer der Tauchgänge nur durch die Nahrungsvorräte an Bord begrenzt ist.Surrendered 26 November 1918. Gegenwärtig betreiben sechs Nationen nuklear getriebene Boote dies sind die Vereinigten Staaten von Amerika, Russland, Frankreich, Großbritannien, die Volksrepublik China und Indien. September 1954 das erste Atom-U-Boot in Dienst gestellt. Mit der amerikanischen USS Nautilus wurde am 30. Ein Atom-U-Boot ist ein Unterseeboot, das die Energie für seinen Antrieb und seine Bordsysteme aus einem oder mehreren Kernreaktoren bezieht. Atomic submarines have the advantage of an almost unlimited range compared to the usually smaller and more cost-efficient submarines with conventional drives, such as the electric drive, and the fact that in the case of atomic submarines, the duration of the dives can only be reduced by The food supplies on board is limited. At present, six nations are operating nuclear-powered boats These are the United States of America, Russia, France, Great Britain, the People's Republic of China and India.
The first nuclear submarine was put into service on Septemwith the American USS Nautilus. Atom-U-Boot An atomic submarine is a submarine that refers to the energy for its propulsion and its system of one or more nuclear reactors.
