The Imperial German Navy or the Kaiserliche Marine was the navy of the German Empire, which existed between 1871 and 1919. It grew out of the small Prussian Navy, which was mainly for coast defence. Kaiser Wilhelm II greatly expanded the navy. The key leader was Admiral Alfred von Tirpitz, who greatly expanded the size and quality of the navy, while adopting the sea power theories of American strategist Alfred Thayer Mahan. The result was a naval arms race with Britain, as the German navy grew to become one of the greatest maritime forces in the world, second only to the Royal Navy.
The Kriegsmarine was the navy of Nazi Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war Reichsmarine (1919–1935) of the Weimar Republic. The Kriegsmarine was one of three official branches, along with the Heer and the Luftwaffe, of the Wehrmacht, the German armed forces from 1935 to 1945.
Otto Ernst Lindemann was a German Kapitän zur See. He was the only commander of the battleship Bismarck during its eight months of service in World War II.
Hermann Bauer was a German naval officer who served as commander of the U-boat forces of the Kaiserliche Marine during World War I. In addition to his World War I career, Bauer is well known as the author of the book Das Unterseeboot, a treatise on the design and operation of U-boats, which was later translated into English by Hyman G. Rickover. Rickover's translation became a basic text for the US submarine service.
SMS Zähringen was the third Wittelsbach-class pre-dreadnought battleship of the German Imperial Navy. Laid down in 1899 at the Germaniawerft shipyard in Kiel, she was launched on 12 June 1901 and commissioned on 25 October 1902. Her sisters were Wittelsbach, Wettin, Schwaben and Mecklenburg; they were the first capital ships built under the Navy Law of 1898, brought about by Admiral Alfred von Tirpitz. The ship, named for the former royal House of Zähringen, was armed with a main battery of four 24 cm (9.4 in) guns and had a top speed of 18 knots.
SMS Preussen was the fourth of five pre-dreadnought battleships of the Braunschweig class, built for the German Kaiserliche Marine. She was laid down in April 1902, was launched in October 1903, and was commissioned in July 1905. Named for the state of Prussia, the ship was armed with a battery of four 28 cm (11 in) guns and had a top speed of 18 knots. Like all pre-dreadnoughts built at the turn of the century, Preussen was quickly made obsolete by the launching of the revolutionary HMS Dreadnought in 1906; as a result, she saw only limited service with the German fleet.
SMS Braunschweig was the first of five pre-dreadnought battleships of the Braunschweig class built for the German Kaiserliche Marine. She was laid down in October 1901, launched in December 1902, and commissioned in October 1904. She was named after the Duchy of Brunswick. The ship was armed with a battery of four 28 cm (11 in) guns and had a top speed of 18 knots. Like all other pre-dreadnoughts built at the turn of the century, Braunschweig was quickly made obsolete by the launching of the revolutionary HMS Dreadnought in 1906; as a result, her career as a front-line battleship was cut short.
SMS Mecklenburg was the fifth ship of the Wittelsbach class of pre-dreadnought battleships of the German Imperial Navy. Laid down in May 1900 at the AG Vulcan shipyard in Stettin, Germany, she was finished in May 1903. Her sister ships were Wittelsbach, Zähringen, Wettin, and Schwaben; they were the first capital ships built under the Navy Law of 1898, championed by Admiral Alfred von Tirpitz. Mecklenburg was armed with a main battery of four 24-centimeter (9.4 in) guns and had a top speed of 18 knots.
SMS Hannover was the second of five Deutschland-class pre-dreadnought battleships of the German Imperial Navy. Hannover and the three subsequently constructed ships differed slightly from the lead ship Deutschland in their propulsion systems and slightly thicker armor. Hannover was laid down in November 1904, launched in May 1905, and commissioned into the High Seas Fleet in October 1907. The ship was armed with a battery of four 28 cm (11 in) guns and had a top speed of 18 knots. The ships of her class were already outdated by the time they entered service, being inferior in size, armor, firepower, and speed to the revolutionary new British battleship HMS Dreadnought.
SMS Schwaben was the fourth ship of the Wittelsbach class of pre-dreadnought battleships of the German Imperial Navy. Schwaben was built at the Imperial Dockyard in Wilhelmshaven. She was laid down in 1900, and completed in April 1904. Her sister ships were Wittelsbach, Zähringen, Wettin and Mecklenburg; they were the first capital ships built under the Navy Law of 1898, championed by Admiral Alfred von Tirpitz. Schwaben was armed with a main battery of four 24-centimeter (9.4 in) guns and had a top speed of 18 knots.
SMS Elsass was the second of five pre-dreadnought battleships of the Braunschweig class in the German Imperial Navy. She was laid down in May 1901, launched in May 1903, and commissioned in November 1904, though an accident during sea trials delayed her completion until May 1905. She was named for the German province of Elsass, now the French region of Alsace. Her sister ships were Braunschweig, Hessen, Preussen and Lothringen. The ship was armed with a battery of four 28 cm (11 in) guns and had a top speed of 18 knots. Like all other pre-dreadnoughts built at the turn of the century, Elsass was quickly made obsolete by the launching of the revolutionary HMS Dreadnought in 1906; as a result, her career as a frontline battleship was cut short.
SMS Deutschland was the first of five Deutschland-class pre-dreadnought battleships built for the German Kaiserliche Marine. The ship was armed with a main battery of four 28 cm (11 in) guns in two twin turrets. She was built at the Germaniawerft shipyard in Kiel, where she was laid down in June 1903 and launched in November 1904. She was commissioned on 3 August 1906, a few months ahead of HMS Dreadnought. The latter, armed with ten large-caliber guns, was the first of a revolutionary new standard of "all-big-gun" battleships that rendered Deutschland and the rest of her class obsolete.
Hans-Jürgen "Hansjürgen" Rudolf Reinicke was a Kapitän zur See, commander of heavy cruiser Prinz Eugen, in Nazi Germany's Kriegsmarine during the Second World War and recipient of the Knight's Cross of the Iron Cross.
Walter Hennecke was a German admiral during World War II. He was awarded the Knight's Cross of the Iron Cross by Hitler for "a feat unprecedented in the annals of coastal defense", when he comprehensively damaged Cherbourg Harbour prior to surrendering it to Allied forces.
SMS Medusa was a member of the ten-ship Gazelle class of light cruisers that were built for the German Kaiserliche Marine in the late 1890s and early 1900s. The Gazelle class was the culmination of earlier unprotected cruiser and aviso designs, combining the best aspects of both types in what became the progenitor of all future light cruisers of the Imperial fleet. Built to be able to serve with the main German fleet and as a colonial cruiser, she was armed with a battery of ten 10.5 cm (4.1 in) guns and a top speed of 21.5 knots. Medusa served in all three German navies—the Kaiserliche Marine, the Reichsmarine of Weimar Germany, and the Kriegsmarine of Nazi Germany—over the span of over forty years.
SMS Amazone was the sixth member of the ten-ship Gazelle class of light cruisers that were built for the German Kaiserliche Marine in the late 1890s and early 1900s. The Gazelle class was the culmination of earlier unprotected cruiser and aviso designs, combining the best aspects of both types in what became the progenitor of all future light cruisers of the Imperial fleet. Built to be able to serve with the main German fleet and as a colonial cruiser, she was armed with a battery of ten 10.5 cm (4.1 in) guns and a top speed of 21.5 knots.
SMS Hamburg was the second member of the seven-vessel Bremen class of light cruisers, built for the German Kaiserliche Marine in the early 1900s. She and her sister ships were ordered under the 1898 Naval Law that required new cruisers be built to replace obsolete vessels in the fleet. The design for the Bremen class was derived from the preceding Gazelle class, utilizing a larger hull that allowed for additional boilers that increased speed. Named for the city of Hamburg, the ship was armed with a main battery of ten 10.5 cm (4.1 in) guns and had a top speed of 22 knots.
A type commander in the Kriegsmarine was a permanently assigned administrative officer in the organization of the Kriegsmarine which oversaw the development, deployment, and in some cases operational activities of the various classes of German naval vessels. Due to cross jurisdiction with the Navy group commanders, who tactically commanded all vessels at sea, some type commanders were little more than ceremonial officers who held a title with little authority. Others, such as Karl Dönitz who commanded the German U-boat force, exercised near total independence and held enormous authority, both operationally and administrative.
Hans Karl Meyer, was a German naval officer and Konteradmiral in the Kriegsmarine during World War II and later Flotilla admiral of the German Navy. Meyer was most notable for being commander of the battleship Tirpitz, of 1/Seekriegsleitung (SKL) Operations of Naval Command and being one of six Kriegsmarine admirals who were subordinated after World War II in the new German Navy.
SMS G11 was a V1-class large torpedo boat of the Imperial German Navy. She was built by the Germaniawerft shipyard at Kiel between 1911 and 1912, completing on 8 August 1912.
