The Königsberg class, sometimes referred to as the K class, was a class of light cruisers of the German Reichsmarine and Kriegsmarine. The class comprised three ships named after German cities: Königsberg, Karlsruhe, and Köln, all built between 1926 and 1930. These ships were the first of the Reichsmarine with a modern cruiser design; their predecessor, Emden, was based on World War I-era designs. They were armed with a main battery of nine 15 cm (5.9 in) guns and with twelve 50 cm (20 in) torpedo tubes.
The Admiral Hipper class was a group of five heavy cruisers built by Nazi Germany's Kriegsmarine beginning in the mid-1930s. The class comprised Admiral Hipper, the lead ship, Blücher, Prinz Eugen, Seydlitz, and Lützow. Only the first three ships of the class saw action with the German Navy during World War II. Work on Seydlitz stopped when she was approximately 95 percent complete; it was decided to convert her into an aircraft carrier, but this was not completed either. Lützow was sold incomplete to the Soviet Union in 1940.
The German torpedo boats of World War II were armed principally, if not exclusively, with torpedoes and varied widely in size. They were not small schnellboote but small seagoing vessels, the larger of which were comparable to destroyers. During World War II, German torpedo boats were administratively grouped into several torpedo-boat flotillas.
The Type 35 torpedo boat was a class of a dozen torpedo boats built for Nazi Germany's Kriegsmarine in the late 1930s. Although the first boats were completed a few months after the start of World War II in September 1939, none of them were able to participate in the Norwegian Campaign of April–June 1940. They began escorting convoys and minelayers as they laid their minefields in the North Sea and English Channel in July. Most of the boats were transferred to Norway in November where they made an unsuccessful attempt to attack shipping along the Scottish coast that saw one boat sunk.
The Moltke class was a class of two "all-big-gun" battlecruisers of the German Imperial Navy built between 1909–1911. Named SMS Moltke and SMS Goeben, they were similar to the previous battlecruiser Von der Tann, but the newer design featured several incremental improvements. The Moltkes were slightly larger, faster, and better armored, and had an additional pair of 28 cm (11 in) guns.
SMS G42 was a 1913 Type Large Torpedo Boat of the Imperial German Navy during World War I, and the 18th ship of her class.
The Brummer class consisted of two light mine-laying cruisers built for the Imperial German Navy in World War I: SMS Brummer and SMS Bremse. When the war broke out, the Germans had only two older mine-laying cruisers. Although most German cruisers were fitted for mine-laying, a need for fast specialized ships existed. The Imperial Russian Navy had ordered sets of steam turbines for the first two ships of the Svetlana-class cruisers from the AG Vulcan shipyard in Stettin. This machinery was confiscated on the outbreak of war and used for these ships. Both vessels were built by AG Vulcan.
The Karlsruhe class of light cruisers was a pair of two ships built for the German Imperial Navy before the start of World War I. The ships—SMS Karlsruhe and Rostock—were very similar to the previous Magdeburg-class cruisers, mounting the same armament and similar armor protection, though they were larger and faster than the earlier ships. Both vessels were laid down in 1911, and launched one day apart, on 11 and 12 November 1912. Karlsruhe joined the fleet in January 1914, but fitting out work lasted slightly longer on her sister; Rostock was commissioned the following month.
The S90 class of torpedo boats was a group of large torpedo boats built for the German Imperial Navy in the early 20th century. They were Hochsee-Torpedoboot built to varying designs by Schichau at Elbing and Germaniawerft at Kiel. German torpedo boats were designated by shipbuilder, with the first letter of their designation reflecting their builder.
The Siegfried class was a group of six coastal defense ships built by the German Kaiserliche Marine in the late 19th century. The ships were intended to protect the German coastline from naval attacks. The class comprised the lead ship Siegfried, along with her sisters Beowulf, Frithjof, Heimdall, Hildebrand, and Hagen. All six ships were named after Norse mythological figures. Two further vessels, the Odin class, were built to a similar design but were not identical.
The Bremen class was a group of seven light cruisers built for the Imperial German Navy in the early 1900s. The seven ships, Bremen, Hamburg, Berlin, Lübeck, München, Leipzig, and Danzig, were an improvement upon the previous Gazelle class. They were significantly larger than the earlier class, and were faster and better armored. Like the Gazelles, they were armed with a main battery of ten 10.5 cm SK L/40 guns and a pair of torpedo tubes.
The Kolberg class was a group of four light cruisers built for the German Imperial Navy and used during the First World War. The class comprised four vessels: SMS Kolberg, the lead ship, Mainz, Cöln, and Augsburg. The ships were built between 1908 and 1910, and two, Kolberg and Augsburg, were modernized in 1916–1917. The ships were armed with a main battery of twelve 10.5 cm SK L/45 guns and had a design speed of 25.5 knots. The first three ships were assigned to the reconnaissance forces of the High Seas Fleet; Augsburg was instead used as a torpedo and gunnery training ship.
The V25 class was a class of torpedo boat built for the Imperial German Navy. It was numerically the largest class ever built for the High Seas Fleet, consisting of 71 ships. Of the class, 32 were sunk during World War I, several to mines in the North Sea and Baltic Sea. Of those that survived the war 29 were scuttled with the German fleet at Scapa Flow, one was destroyed by a mine on the way there, four were given to Britain and were not scuttled while one was given to Italy and France.
The Type 37 torpedo boat was a class of nine torpedo boats built for Nazi Germany's Kriegsmarine during World War II. Completed in 1941–1942, one boat helped to escort a commerce raider passing through the English Channel into the Atlantic Ocean in late 1941, but their first major action was in early 1942 when they formed part of the escort for a pair of battleships and a heavy cruiser through the Channel back to Germany in the Channel Dash. Two pairs of boats were sent to France at different times in mid-1942 and were part of the escort during an unsuccessful attempt to pass a different commerce raider back through the Channel in October. One boat was assigned to the Torpedo School as a training ship in mid-1942 and the others followed in the next year.
SMS Sachsen was the third of four dreadnought-type Bayern-class battleships built, but never finished, for the German Kaiserliche Marine in the 1910s. This ship is sometimes considered to be part of a sub-class with her sister Württemberg. Like the other members of the class, she was to be armed with the same main battery of eight 38 cm (15 in) guns in four gun turrets, but she differed from the other members of her class in her propulsion system. She exchanged the steam turbine on her center propeller shaft in favor of a diesel engine. She was laid down in April 1914 at the Germaniawerft shipyard, but the start of World War I in July slowed work on the ship; she was launched in November 1916, but as resources were diverted to more pressing projects, including U-boat construction, work stopped completely when the ship was about nine months from completion. Some components of her propulsion system were reused in several of the Type U 151 submarines. The Treaty of Versailles that ended the war in June 1919 specified that all warships under construction in Germany were to be destroyed, and Sachsen was accordingly sold for scrap in 1920 and dismantled the following year.
Torpedo boats had been operated by the Imperial German Navy from the very beginning. The "Imperial Navy" existed between 1871 and 1919. In 1870 there had been 14 tugboats and harbour vessels and 7 rowing boats, which had been armed with spar torpedoes to protect the Elbe and Weser during the Franco-Prussian War.
SMS G196 was a S-138-class large torpedo boat of the Imperial German Navy. She was built by the Germaniawerft shipyard at Kiel between 1910 and 1911, and was launched on 25 May 1911, entering service later that year. She served throughout the First World War, taking part in the Battle of Heligoland Bight on 28 August 1914. She was renamed T196 in February 1918.
The German torpedo boat T3 was one of a dozen Type 35 torpedo boats built for the Kriegsmarine during the late 1930s. Completed during the Second World War in 1940, she was assigned to escort duties between Germany and Occupied Norway in August before beginning to escort minelayers in the North Sea the following month. The boat was sunk in France by British bombers in September and was refloated the following year. T3 was assigned to the Torpedo School when her repairs were completed in 1943. She returned to active duty a year later and escorted German ships as they bombarded Soviet positions. The boat sank a Soviet submarine in early 1944 and she struck a mine in March 1945 and sank with heavy loss of life.
The German torpedo boat T14 was one of nine Type 37 torpedo boats built for the Kriegsmarine during World War II. Completed in mid-1941, she helped escort several commerce raiders passing through the English Channel in 1941 and 1942 in addition to blockade runners through the Bay of Biscay into the Atlantic. The boat remained in France until November 1943, during which time she laid several minefields, and was then assigned to the Torpedo School before beginning a lengthy refit in 1944. T14 was assigned to convoy escort duties in the Skagerrak around the beginning of 1945 and survived the war. The boat was allocated to the United States after the war, but she was transferred to France in 1947 and renamed Dompaire. Unused by the French Navy, the boat was stricken from the Navy List in 1951 and subsequently scrapped.
The Ålesund class was a proposed class of destroyers planned for the Royal Norwegian Navy. Construction began on two ships in 1938, but the incomplete ships were captured during the German invasion of Norway in 1940. While Germany continued construction works on the two destroyers, neither were completed, with one sunk by sabotage in 1944 and the other by British bombers in 1945. The Norwegians raised one of the destroyers and attempted to complete it, but the incomplete ship was sold for scrap in 1956.
