HDW
Howaldtswerke-Deutsche Werft GmbH (often abbreviated HDW) is a German shipbuilding company, headquartered in Kiel. It is part of the ThyssenKrupp Marine Systems (TKMS) group, owned by ThyssenKrupp. The Howaldtswerke shipyard was founded in Kiel in 1838 and merged with Hamburg-based Deutsche Werft to form Howaldtswerke-Deutsche Werft (HDW) in 1968. The company's shipyard was formerly used by Friedrich Krupp Germaniawerft until the end of World War II. History HDW was founded October 1, 1838 in Kiel by engineer August Howaldt and entrepreneur under the name ''Maschinenbauanstalt und Eisengießerei Schweffel & Howaldt'' (Machine Factory and Iron Foundry Schweffel & Howaldt), initially building boilers. The first steam engine for naval purposes was built in 1849 for ''Von der Tann'', a gunboat for the small navy of Schleswig-Holstein. In 1850, the company built an early submarine, ''Brandtaucher'', designed by Wilhelm Bauer. It had been intended to build the boat in Rendsburg ...

August Howaldt
August Ferdinand Howaldt (23 October 1809 – 4 August 1883) was a German engineer and ship builder. The German sculptor Georg Ferdinand Howaldt was his brother. Biography Born in Braunschweig, the son of the silversmith David Ferdinand Howaldt, with whom he got his first practice working in metal, Howaldt made an apprenticeship in Hamburg and became a ''practical mechanicus''.

U-boat
U-boats are Submarine#Military, naval submarines operated by Germany, including during the World War I, First and Second World Wars. The term is an Anglicization#Loanwords, anglicized form of the German word , a shortening of (), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also known as U-boats. U-boats are most known for their unrestricted submarine warfare in both world wars, trying to Commerce raiding, disrupt merchant traffic towards the UK and force the UK out of the war. In World War I, Germany intermittently waged unrestricted submarine warfare against the United Kingdom, UK: a first campaign in 1915 was abandoned after strong protests from the US but in 1917 the Germans, facing deadlock on the continent, saw no other option than to resume the campaign in February 1917. The renewed campaign failed to achieve its goal mainly because of the introduction of Convoys in World War I, convoys. Instead the campaign ensured final defeat ...

Kiel
Kiel ( ; ) is the capital and most populous city in the northern Germany, German state of Schleswig-Holstein. With a population of around 250,000, it is Germany's largest city on the Baltic Sea. It is located on the Kieler Förde inlet of the Bay of Kiel and lies in the southeast of the Jutland Peninsula, on the mouth of the Schwentine River, approximately northeast of Hamburg. The world's busiest artificial waterway, the Kiel Canal, has a terminus in Kiel's Holtenau district. This canal connects the Baltic to the North Sea, with its other end in Brunsbüttel. Most of Kiel is part of Holstein. The boroughs north of the Schwentine also belong to Wagria, while those north of the Kiel Canal are historically part of Southern Schleswig. Kiel is one of Germany's major maritime centres, known for a variety of international sailing events, including the annual Kiel Week, which is the biggest sailing event in the world. Kiel is also known for the Kiel mutiny, Kiel Mutiny, when sailors re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunboat
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies. History Pre-steam era In the age of sail, a gunboat was usually a small undecked vessel carrying a single smoothbore cannon in the bow, or just two or three such cannons. A gunboat could carry one or two masts or be oar-powered only, but the single-masted version of about length was most typical. Some types of gunboats carried two cannon, or else mounted a number of swivel guns on the railings. The small gunboat had advantages: if it only carried a single cannon, the boat could manoeuvre in shallow or restricted areas – such as rivers or lakes – where larger ships could sail only with difficulty. The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and quick to build, naval forces favoured swarm ...

Schleswig-Holstein
Schleswig-Holstein (; ; ; ; ; occasionally in English ''Sleswick-Holsatia'') is the Northern Germany, northernmost of the 16 states of Germany, comprising most of the historical Duchy of Holstein and the southern part of the former Duchy of Schleswig. Its capital city is Kiel; other notable cities are Lübeck and Flensburg. It covers an area of , making it the 5th smallest German federal state by area (including the city-states). Historically, the name can also refer to a larger region, containing both present-day Schleswig-Holstein and the former South Jutland County (Northern Schleswig; now part of the Region of Southern Denmark) in Denmark. Schleswig, named South Jutland at the time, was under Danish control during the Viking Age, but in the 12th century it became a duchy within Denmark due to infighting in the Danish Royal House. It bordered Holstein, which was a part of the Holy Roman Empire. Beginning in 1460, the King of Denmark ruled both Schleswig and Holstein as the ...

Submarine
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as ''boats'' rather than ''ships'' regardless of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navy, navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; Blockade runner, blockade running; Ballistic missile submarine, nuclear deterrenc ...

Brandtaucher
''Brandtaucher'' ( German for ''Fire-diver'') was a submersible designed by the Bavarian inventor and engineer Wilhelm Bauer and built by Schweffel & Howaldt in Kiel for Schleswig-Holstein's Flotilla (part of the '' Reichsflotte'') in 1850. The ''Brandtaucher'' is the oldest known surviving submarine in the world. History In January 1850, Bauer, a cavalryman during the German-Danish War, designed ''Brandtaucher'' as a way to end the Danish naval blockade of Germany. A submarine could affix mines on hulls of enemy ships undetected, and detonate them from a safe distance. Bauer's early sketch attracted the attention of the Minister of Marine, who allowed him to construct a model. The model was demonstrated in Kiel harbour in front of naval dignitaries. Its satisfactory performance led to the construction of a full-scale model, which was funded by contributions from army personnel and local civilians. Due to the inadequate funding, the scale of the boat had to be downgraded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rendsburg
Rendsburg (, also ''Rensborg'', , also ''Rensborg'') is a town on the Eider (river), River Eider and the Kiel Canal in the central part of Schleswig-Holstein, Germany.

Wilhelm Bauer
Wilhelm Bauer (; 23 December 1822 – 20 June 1875) was a German marine engineer and inventor who built several hand-powered submarines. Biography Wilhelm Bauer was born in Dillingen in the Kingdom of Bavaria. His father was a sergeant in a Bavarian cavalry regiment. After an apprenticeship as a wood turner, Bauer also joined the army. Working as an artillery engineer, he witnessed the German/Danish war for Schleswig-Holstein between 1848 and 1851. Seeing how the Prussian coast was easily blockaded by the Danish navy, Bauer quickly developed a plan to build a new type of submersible ship to help break the blockade. He began studying hydraulics and ship construction. However, before his studies could get very far, the troops of the German Confederation decided to withdraw and surrendered Schleswig-Holstein to Denmark. However, Bauer was determined to realize his plan and left the Bavarian Army to join the forces of Schleswig-Holstein. It proved very hard for Bauer, wh ...
