SM UB-4
Seiner MajestätGerman: "His Majesty's" ''UB-4'' was a German Type UB I submarine (U-boat) in the German Imperial Navy () during World War I. She was sunk by a British Q-ship disguised as a fishing smack in August 1915. ''UB-4'' was ordered in October 1914 and was laid down at the Germaniawerft shipyard in Kiel in November. ''UB-4'' was a little more than in length and displaced between , depending on whether surfaced or submerged. She carried two torpedoes for her two bow torpedo tubes and was also armed with a deck-mounted machine gun. ''UB-4'' was broken into sections and shipped by rail to Antwerp for reassembly. She was launched and commissioned as SM ''UB-4'' in March 1915."SM" stands for "Seiner Majestät" () and combined with the ''U'' for ''Unterseeboot'' would be translated as ''His Majesty's Submarine''. ''UB-4'' conducted the first sortie of the Flanders Flotilla in April, during which she sank the Belgian Relief ship , the first ship credited to the flotilla. ...

German Type UB I Submarine
The Type ''UB I'' submarine (sometimes known as the ''UB-1'' class) was a class of small coastal submarines (U-boats) built in Germany at the beginning of the First World War. Twenty boats were constructed, most of which went into service with the German Imperial Navy () Boats of this design were also operated by the Austro-Hungarian Navy (''Kaiserliche und Königliche Kriegsmarine'' ''or'' K.u.K. Kriegsmarine) and the Bulgarian Navy. In the Austro-Hungarian Navy, it was called the ''U-10'' class. Built to meet the need for small maneuverable submarines able to operate in the narrow, shallow seas off Flanders, the vessels were intended to be quickly constructed, then shipped by rail and assembled at their port of operation. The design effort began in mid-August 1914 and by mid-October the first 15 boats were ordered from two German shipyards. The German Imperial Navy subsequently ordered an additional pair of boats to replace two sold to Austria-Hungary, who ordered a f ...

Smack (ship)
A smack was a traditional fishing boat used off the coast of Britain and the Atlantic coast of America for most of the 19th century and, in small numbers, up to the Second World War. Many larger smacks were originally Cutter (ship), cutter-rigged sailing boats until about 1865, when smacks had become so large that cutter main booms were unhandy. The smaller smacks retained the gaff cutter rig. The larger smacks were lengthened and re-rigged and new Ketch, ketch-rigged smacks were built, but boats varied from port to port. Some boats had a topsail on the mizzen mast, while others had a bowsprit carrying a jib. Large numbers of smacks operated in fleets from ports in the UK such as Brixham, Grimsby and Lowestoft as well as at locations along the Thames Estuary. In England the sails were white cotton until a proofing coat was applied, usually after the sail was a few years old. This gave the sails its distinctive red ochre colour, which made them a picturesque sight in large numbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cora ...

Minelayer
A minelayer is any warship, submarine, military aircraft or land vehicle deploying explosive mines. Since World War I the term "minelayer" refers specifically to a naval ship used for deploying naval mines. "Mine planting" was the term for installing controlled mines at predetermined positions in connection with coastal fortifications or harbor approaches that would be detonated by shore control when a ship was fixed as being within the mine's effective range. An army's special-purpose combat engineering vehicles used to lay landmines are sometimes called "minelayers". Etymology Before World War I, mine ships were termed mine planters generally. For example, in an address to the United States Navy ships of Mine Squadron One at Portland, England, Admiral Sims used the term "mine layer" while the introduction speaks of the men assembled from the "mine planters". During and after that war the term "mine planter" became particularly associated with defensive coastal fortifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Type UC I Submarine
The Type UC I coastal submarines were a class of small minelaying U-boats built in Germany during the early part of World War I. They were the first operational minelaying submarines in the world (although the Russian submarine Krab (1912), Russian submarine ''Krab'' was laid down earlier). A total of fifteen boats were built. The class is sometimes also referred to as the ''UC-1'' class after , the class leader. The Italian X-class submarine (1916), X-class submarine was a reverse-engineered and modified type of the UC-1-class. Design These submarines were designed by Dr. Werner of the Torpedo Inspectorate, and based on the German Type UB I submarine, Type UB I small coastal submarines, with a revised bow section housing inclined minelaying tubes and uprated engines to compensate for the increased displacement and less streamlined form. The boats' sole armament was six internal mine tubes with 12 mines, although SM UC-11, ''UC-11'' was fitted with a single external torpedo tub ...

Mine (naval)
A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to anti-personnel and other land mines, and unlike purpose launched naval depth charges, they are deposited and left to wait until, depending on their fuzing, they are triggered by the approach of or contact with any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to create "safe" zones protecting friendly sea lanes, harbours, and naval assets. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake a resource-intensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flanders
Flanders ( or ; ) is the Dutch language, Dutch-speaking northern portion of Belgium and one of the communities, regions and language areas of Belgium. However, there are several overlapping definitions, including ones related to culture, language, politics, and history, and sometimes involving neighbouring countries. The demonym associated with Flanders is Flemings, Fleming, while the corresponding adjective is Flemish people, Flemish, which can also refer to the collective of Dutch dialects spoken in that area, or more generally the Belgian variant of Standard Dutch. Most Flemings live within the Flemish Region, which is a federal state within Belgium with its own elected government. However, like Belgium itself, the official capital of Flanders is the City of Brussels, which lies within the Brussels, Brussels-Capital Region, not the Flemish Region, and the majority of residents there are French speaking. The powers of the Flemish Government in Brussels are limited mainly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Army (German Empire)
The Imperial German Army (1871–1919), officially referred to as the German Army (), was the unified ground and air force of the German Empire. It was established in 1871 with the political unification of Germany under the leadership of Prussia, and was dissolved in 1919, after the defeat of the German Empire in World War I (1914–1918). In the Federal Republic of Germany, the term refers to the German Army, the land component of the . Formation and name The states that made up the German Empire contributed their armies; within the German Confederation, formed after the Napoleonic Wars, each state was responsible for maintaining certain units to be put at the disposal of the Confederation in case of conflict. When operating together, the units were known as the Federal Army (). The Federal Army system functioned during various conflicts of the 19th century, such as the First Schleswig War from 1848 to 1852. However, by the time of the Second Schleswig War of 1864, tensio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flanders Flotilla
The Flanders U-boat flotillas were Imperial German Navy formations set up to prosecute the Atlantic U-boat Campaign (World War I), U-boat campaign against Allied shipping in the Western Approaches (British Home Waters) during the First World War. Originally operating as a flotilla, it was split in two during the latter part of the war. The Flanders flotilla was constituted in March 1915 at the port of Bruges in occupied Belgium. Commanded by Karl Bartenbach, the force comprised nine German Type UB II submarine, UB- and seven German Type UC II submarine, UC- type U-boats, small mass-produced coastal types suited for operations in the closed waters of the English Channel, Channel and the North Sea. UB boats were prefabricated in Germany and brought in sections to Bruges and assembled. The boats used Zeebrugge and Ostend as exit ports; UC minelayers joined in late 1915. Throughout the campaign the Flotilla grew, though losses also remained high, as the unit bore a considerable propo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Launch (ship)
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 many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the 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 oldest, most familiar, and most widely used is the end-on la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
