Stickleback-class Submarine
The ''Stickleback''-class submarines were midget submarines of the British Royal Navy initially ordered as improved versions of the older s. They were designed to allow British defences to practice defending against midget submarines since it was theorised that the Soviet Union had or could develop such craft. The Royal Navy developed plans to use these craft to carry a 15-kiloton nuclear naval mine (based on the Red Beard weapon) codenamed Cudgel into Soviet harbours. The project was unsuccessful as there were problems finding and paying for the necessary fissile material. Boats There were four boats, launched 1954–1955:Gardiner and Chumbley, p. 527 *X51 ''Stickleback'', launched 1 October 1954, sold to the Royal Swedish Navy in 1958 and was renamed ''Spiggen'' (Swedish name for "Stickleback"). After a period on display at the Imperial War Museum Duxford, and then in storage at Portsmouth Naval Dockyard, X51 was moved to the Scottish Submarine Centre The Scottish S ...

Midget Submarine
A midget submarine (also called a mini submarine) is any submarine under 150 tons, typically operated by a crew of one or two but sometimes up to six or nine, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff. Both military and civilian midget submarines have been built. Military types work with surface ships and other submarines as mother ships. Civilian and non-combatant military types are generally called submersibles and normally work with surface ships. Most early submarines would now be considered midget submarines, such as the United States Navy's and the British Royal Navy's (both named for the same John Philip Holland, designer). Military submarines Uses Midget submarines are best known for harbor penetration, although only two World War II boats, the British X-class submarine, X-craft and the unsuccessful Welman subm ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. 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 superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive 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 mined areas, precise locations remain secret; and non-complying individ ...

Red Beard (nuclear Weapon)
Red Beard was the first British tactical nuclear weapon. It was carried by Royal Air Force (RAF) English Electric Canberra medium bombers and the V bomber force and by Supermarine Scimitars, de Havilland Sea Vixens, and Blackburn Buccaneers of the Royal Navy's (RN) Fleet Air Arm (FAA). Developed to Operational Requirement OR.1127,Public Record Office, London. AIR 2/17322-e041-P01. it was introduced in 1961, entered service in 1962. It was replaced by the WE.177 in the early 1970s and was withdrawn from service in 1971. Design Red Beard was an unboosted fission weapon that used a composite core (mixed core in British terminology of the time). The composite core used both weapons-grade plutonium and weapons-grade uranium-235, and was intended to minimise the risk of pre-detonation that was a feature of all-plutonium designs of that period with yields larger than 10 kilotons (kt). An added benefit of the composite core was a more economical use of fissile material. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, 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 th ...

Royal Swedish Navy
The Swedish Navy ( sv, Svenska marinen) is the naval branch of the Swedish Armed Forces. It is composed of surface and submarine naval units – the Fleet () – as well as marine units, the Amphibious Corps (). In Swedish, vessels of the Swedish Navy are given the prefix "HMS", short for (His/Her Majesty's Ship). In English, this is sometimes changed to "HSwMS" ("His Swedish Majesty's Ship") to differentiate Swedish vessels from those of the British Royal Navy. Founded under King Gustav I in 1522, the Swedish navy is one of the oldest continuously serving navies in the world, celebrating its 500th anniversary in 2022. History Early Swedish kings ( 9th–14th centuries) organised a Swedish Navy along the coastline through . This involved combined rowing and sailing ships (without artillery). This system became obsolete with the development of society and changes in military technology. No later than in the 14th century, the duty to serve in was replaced by a tax. ...

Portsmouth Naval Dockyard
His Majesty's Naval Base, Portsmouth (HMNB Portsmouth) is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Clyde and HMNB Devonport). Portsmouth Naval Base is part of the city of Portsmouth; it is located on the eastern shore of Portsmouth Harbour, north of the Solent and the Isle of Wight. Until the early 1970s, it was officially known as Portsmouth Royal Dockyard (or HM Dockyard, Portsmouth); thereafter the term 'Naval Base' gained currency, acknowledging a greater focus on personnel and support elements alongside the traditional emphasis on building, repairing and maintaining ships. In 1984 Portsmouth's Royal Dockyard function was downgraded and it was formally renamed the 'Fleet Maintenance and Repair Organisation' (FMRO). The FMRO was privatized in 1998, and for a time (from 2002 to 2014), shipbuilding, in the form of Shipbuilding#Modern shipbuilding manufacturing techniques, block construction, returned. Around 2000, the designat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Helensburgh
Helensburgh (; gd, Baile Eilidh) is an affluent coastal town on the north side of the Firth of Clyde in Scotland, situated at the mouth of the Gareloch. Historically in Dunbartonshire, it became part of Argyll and Bute following local government reorganisation in 1996. Geography and geology Helensburgh is northwest of Glasgow. The town faces south towards Greenock across the Firth of Clyde, which is approximately wide at this point. Ocean-going ships can call at Greenock, but the shore at Helensburgh is very shallow, although to the west of the town the Gareloch is deep. Helensburgh lies at the western mainland end of the Highland Boundary Fault. This means that the hills to the north of Helensburgh lie in the Scottish Highlands, Highlands, whereas the land to the south of Helensburgh is in the Scottish Lowlands, Lowlands or Central Belt of Scotland. Consequently, there is a wide variety of landscape in the surrounding area – for example, Loch Lomond (part of Scotland's ...
