Nazi Germany
Nazi Germany, officially known as the German Reich and later the Greater German Reich, was the German Reich, German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a Totalitarianism, totalitarian dictatorship. The Third Reich, meaning "Third Realm" or "Third Empire", referred to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which the Nazis referred to as the Thousand-Year Reich, ended in May 1945, after 12 years, when the Allies of World War II, Allies defeated Germany and entered the capital, Berlin, End of World War II in Europe, ending World War II in Europe. After Hitler was appointed Chancellor of Germany in 1933, the Nazi Party began to eliminate political opposition and consolidate power. A 1934 German referendum confirmed Hitler as sole ''Führer'' (leader). Power was centralised in Hitler's person, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Type XXIII Submarine
German Type XXIII submarines were the first so-called elektroboote ("electric boats") to become operational. They were small coastal submarines designed to operate in the shallow waters of the North Sea, Black Sea and Mediterranean Sea, where larger Type XXI electric boats were at risk in World War II. They were so small they could carry only two torpedoes, which had to be loaded externally. As with their far larger sisters—the Type XXI—they were able to remain submerged almost all of the time and were faster than conventional U-boats, due to the improved streamlining of their shape, batteries with larger capacity and the snorkel, which allowed the diesel engines to be used while submerged. The Type XXI and XXIII U-boats revolutionized post-war submarine design. Nearly a thousand Type XXIII boats were projected towards the close of World War II, but most of these were either cancelled, scrapped incomplete, or only projected. Background When development began on the Type XX ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

HMS Unicorn (1824)
HMS ''Unicorn'' is a surviving sailing frigate of the successful ''Leda'' class, although the original design had been modified by the time that the ''Unicorn'' was built, to incorporate a circular stern and "small-timber" system of construction. Listed as part of the National Historic Fleet, ''Unicorn'' is now a museum ship in Dundee, Scotland, United Kingdom. She is the oldest ship in Scotland, one of the oldest ships in the world, and one of the last intact warships from the age of sail. As of January 2025, the ship is due to undergo restoration and relocation to a newly restored dry dock (Dundee's East Graving Dock). History HMS ''Unicorn'' was built in peacetime at Chatham Dockyard, Kent and launched in 1824 This was a transitional period for shipbuilding, as suitable timber was becoming more difficult to obtain, and iron was increasingly available. Under the direction of Sir Robert Seppings, then Surveyor of the Royal Navy, ''Unicorn'' was built with diagonal rid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dundee, Scotland
Dundee (; ; or , ) is the List of towns and cities in Scotland by population, fourth-largest city in Scotland. The mid-year population estimate for the locality was . It lies within the eastern central Lowlands on the north bank of the Firth of Tay, which feeds into the North Sea. Under the name of Dundee City, it forms one of the 32 Council areas of Scotland, council areas used for local government in Scotland. Within the boundaries of the Shires of Scotland, historic county of Angus, Scotland, Angus, the city developed into a burgh in the late 12th century and established itself as an important east coast trading port. Rapid expansion was brought on by the Industrial Revolution, particularly in the 19th century when Dundee was the centre of the global jute industry. This, along with its other major industries, gave Dundee its epithet as the city of "jute, jam and journalism". With the decline of traditional industry, the city has adopted a plan to regenerate and reinvent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship's Company
A ship's company or complement comprises all officers, non-commissioned officers and enlisted personnel aboard a naval vessel, excluding civilians and guests. United States Aircraft-capable ships An exception to this rule is the definition of ship's company as it applies to the U.S. Navy and U.S. Marine Corps personnel assigned to aircraft-capable ships of the U.S. Navy, primarily aircraft carriers and amphibious assault ships. In the case of aircraft carriers in the U.S. Navy, the total ship's complement is divided into three categories: # the ship's company physically assigned to the ship, and # the carrier air wing, with its associated strike fighter, U.S. Marine fighter/attack, electronic attack, airborne early warning and helicopter squadrons, and a detachment of a fleet logistics squadron, which is considered a separate "embarked" command, and # the carrier strike group commander and staff, which is also considered an "embarked" command The number of personnel assigned ...

Silent Running (submarine)
Silent running is a stealth mode of operation for naval submarines. The aim is to evade discovery by passive sonar by eliminating superfluous noise: nonessential systems are shut down, the crew is urged to rest and refrain from making any unnecessary sound, and speed is greatly reduced to minimize propeller noise. The protocol has been in use since the latter part of World War I, when hydrophones were invented to detect U-boats. The propellers have a characteristic RPM band in which no cavitation noise arises. Since this rotation speed is usually relatively low, the first electric submarines had special "silent running" engines designed for optimum performance at reduced speed. These required less active cooling (further reducing noise), and were generally equipped with plain bearings rather than ball bearing A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oberleutnant Zur See
(''OLt zS'' or ''OLZS'' in the German Navy, ''Oblt.z.S.'' in the ''Kriegsmarine'') is traditionally the highest rank of Lieutenant in the German Navy. It is grouped as Ranks and insignia of officers of NATO Navies, OF-1 in NATO. The rank was introduced in the Imperial German Navy by renaming the former rank of ''Premier Lieutenant'' in 1890. Within the navy, officers of this rank were simply addressed as ''Herr Oberleutnant''. To distinguish naval officers from those of the army, the suffix ''zur See'' (at sea) was added in official communications, sometimes shortened to ''z.S.'' (''Oblt.z.S.''). The rank has since been used by the ''Reichsmarine'', ''Kriegsmarine'', and ''Bundesmarine''. In the ''Volksmarine'', the rank was originally used in the same way until the suffix ''zur See'' was dropped. In the ''Kriegsmarine'', engineers (''Ingenieur – Ing.'') of the same rank were distinguished as ''Oberleutnant (Ing.)''. See also * Ranks of the German Bundeswehr * Rank insign ...

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before it is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and Electronics, electronic systems, Galley (kitchen), galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performing of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back millennia, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and in addition to the size and weight of the vessel represents a considerable engineering challenge as well as a public spectacle. The process also involves Sailors' superstitions, many traditions intended to invite good luck, such as baptism#Boats and ships, christening by breaking a sacrificial bottle of champagne over the bow (ship), bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The ol ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a shipbuilding, ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in a ship's life; the others are Ceremonial ship launching, launching, Ship commissioning, commissioning, and Ship decommissioning, decommissioning. Earlier, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel ...
