German Submarine U-105 (1940)
German submarine ''U-105'' was a Type IXB U-boat of Nazi Germany's ''Kriegsmarine''. She was ordered on 24 May 1938 as part of Germany's naval rearmament program. Her keel was laid down in Bremen on 16 November 1938. After roughly seven months of construction, she was launched on 15 June 1940 and formally commissioned into the Kriegsmarine on 10 September 1940. During her three-year career, ''U-105'' sank 23 vessels for a total loss of and 1,546 tons before being sunk by the Free French Forces off the coast of Dakar (Senegal) on 2 June 1943. Construction and design Construction ''U-105'' was ordered by Nazi Germany's ''Kriegsmarine'' on 24 May 1938; her keel was laid down on 16 November 1938 by DeSchiMAG AG Weser in Bremen as yard number 968.

Type IXB Submarine
The German Type IXB submarine was a sub-class of the German Type IX submarine built for Nazi Germany's ''Kriegsmarine'' between 1938 and 1940. The U-boats themselves were designed to be fairly large ocean-going submarines. The inspiration for the Type IXB submarine came from the earlier original Type IX submarine, the Type IXA submarine. The design of the IXA was developed to give an increased range, a change which resulted in a slightly heavier overall tonnage. This design was improved even further in the later Type IXC submarines. The class comprised 14 submarines, , , , , , , , , , , , , , and ; twelve were sunk during the war and two scuttled by their crews at the end of the war. The Type IXB submarines were the most successful class of submarine in the war in terms of the total amount to tonnage sunk, with each U-boat sinking an average of over during its career. Design and construction Construction All Type IXB submarines were ordered by the Nazi Germany's ''Kriegsmarine' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Draught (ship)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull (watercraft), hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted Load line (vessel), load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull (watercraft), hull, propellers, or other reference point". That is, the draft or draught is the maximum depth (coordinate), depth of any part of the vessel, ... [...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 ...

Type IXA Submarine
The German Type IXA submarine was a sub-class of the German Type IX submarine built for Nazi Germany's ''Kriegsmarine'' between 1937 and 1938. These U-boats were designed between 1935 and 1936 and were intended to be fairly large ocean-going submarines. The inspiration for the Type IXA submarine came from the German Type I submarine, German Type IA submarine, which had a similar diving depth and identical submerged horsepower. Two of the eight Type IXA submarines ( and ) would become the 6th and 10th most successful U-boats that saw service in World War II, sinking 53 and 35 ships respectively. All of the Type IXA submarines were sunk fairly early in the war except for ''U-37'' and ''U-38'', which were scuttled in May 1945 to prevent them from falling into the hands of the Allies. Construction All Type IXA submarines were ordered by the ''Kriegsmarine'' between 29 July 1936 and 21 November 1936 as part of Plan Z and the overall German plan of re-armament in violation of the Treat ...

Dakar
Dakar ( ; ; ) is the capital city, capital and List of cities in Senegal, largest city of Senegal. The Departments of Senegal, department of Dakar has a population of 1,278,469, and the population of the Dakar metropolitan area was at 4.0 million in 2023. Dakar is situated on the Cap-Vert peninsula, the westernmost point of mainland Africa. Cap-Vert was colonized by the Portuguese people, Portuguese in the early 15th century. The Portuguese established a presence on the island of Gorée off the coast of Cap-Vert and used it as a base for the Atlantic slave trade. Kingdom of France, France took over the island in 1677. Following the abolition of the slave trade and French annexation of the mainland area in the 19th century, Dakar grew into a major regional port and a major city of the French colonial empire. In 1902, Dakar replaced Saint-Louis, Senegal, Saint-Louis as the capital of French West Africa. From 1959 to 1960, Dakar was the capital of the short-lived Mali Federation. ...

Free French Forces
__NOTOC__ The French Liberation Army ( ; AFL) was the reunified French Army that arose from the merging of the Armée d'Afrique with the prior Free French Forces (; FFL) during World War II. The military force of Free France, it participated in the Italian and Tunisian campaigns before joining in the Liberation of France with other Western Allies of World War II. It went on to join the Western Allied invasion of Germany. History The French Liberation Army was created in January 1943 when the Army of Africa () led by General Giraud was combined with the Free French Forces of General de Gaulle. The AFL participated in the campaigns of Tunisia and Italy; during the Italian campaign the AFL was known as the French Expeditionary Corps in Italy ( ''en Italie or CEFI)'' making a quarter of the troops deployed. The AFL was key in the liberation of Corsica, the first French metropolitan department to be liberated. The troops that landed 2 months after D-Day were the 2nd A ...

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 ...

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 ...
