HMS Hotspur (1870)
HMS ''Hotspur'' was a Victorian Royal Navy ironclad ram – a warship armed with guns but whose primary weapon was a ram. Background It had been recognised since the time of the Roman Empire or before that a ship, while it might carry weaponry, was itself a potent weapon if used as a missile against other ships. In the era of sail-powered warships with their intrinsic limitations of speed and manoeuverability the practice of ramming opponents fell by default into disuse, although the concept remained alive. With the advent of steam-powered vessels, with their enhanced speed and lack of dependence for direction on the wind, the ram as a potent weapon of attack gained credibility in Naval circles and in Ship Constructors' departments. This first became apparent in the American Civil War, when many attempts were made by ships on both sides to ram their opponents, with almost uniform lack of success.

1870 Ships
Year 187 ( CLXXXVII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Quintius and Aelianus (or, less frequently, year 940 ''Ab urbe condita''). The denomination 187 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Steam Rams
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. Types ...

Ships Built On The River Clyde
A ship is a large watercraft that travels the world's oceans and other sufficiently deep Sea lane, waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, Naval warfare, warfare, Human migration, migration, colonization, and science. After the 15th century, Columbian Exchange, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a Full-rigged ship, ship-rigged sailing ship with three or more masts, each of which is Square rig, square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Imperial Fortress
Imperial fortress was the designation given in the British Empire to four colonies that were located in strategic positions from each of which Royal Navy squadrons could control the surrounding regions and, between them, much of the planet. History The Imperial fortresses provided not only safe harbours and (with the advent of steam propulsion) coal stores within the area of operation, but also Royal Naval Dockyards where ships of the squadrons could be repaired or maintained without requiring their return to a dockyard in the British Isles. The Imperial fortresses were also locations where military stores were stockpiled and numbers of soldiers sufficient not only for local defence, but also to provide expeditionary forces to work with the Royal Navy in amphibious campaigns and raids on coasts throughout the regions, could be garrisoned. These Imperial fortresses originally included: * Halifax, in Nova Scotia * Bermuda * Gibraltar * Malta They were the lynch pins in Brit ...

Royal Naval Dockyard, Bermuda
HMD Bermuda ( Her/His Majesty's Dockyard, Bermuda) was the principal base of the Royal Navy in the Western Atlantic between American independence and the Cold War. The Imperial fortress colony of Bermuda had occupied a useful position astride the homeward leg taken by many European vessels from the New World since before its settlement by England in 1609. French privateers may have used the islands as a staging place for operations against Spanish galleons in the 16th century. Bermudian privateers certainly played a role in many English and British wars following settlement, with its utility as a base for his privateers leading to the Earl of Warwick, the namesake of Warwick Parish, becoming the most important investor of the Somers Isles Company. Despite this, it was not until the loss of bases on most of the North American Atlantic seaboard (following US independence) threatened Britain's supremacy in the Western Atlantic that the island assumed great importance as a naval bas ...

Particular Service Squadron
In metaphysics, particulars or individuals are usually contrasted with universals. Universals concern features that can be exemplified by various different particulars. Particulars are often seen as concrete, spatiotemporal entities as opposed to abstract entities, such as properties or numbers. There are, however, theories of ''abstract particulars'' or ''tropes''. For example, Socrates is a particular (there's only one Socrates-the-teacher-of-Plato and one cannot make copies of him, e.g., by cloning him, without introducing new, distinct particulars). Redness, by contrast, is not a particular, because it is abstract and multiply instantiated (for example a bicycle, an apple, and a given woman's hair can all be red). In nominalist view everything is particular. Universals in each moment of time from point of view of an observer is the collection of particulars that participates it (even a void collection).

Steamship
A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for ''paddle steamer'' or "SS" for ''screw steamer'' (using a propeller or screw). As paddle steamers became less common, "SS" is assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for ''motor vessel'', so it is not correct to use "SS" for most modern vessels. As steamships were less dependent on wind patterns, new trade routes opened up. The steamship has been described as a "major driver of the first wave of trade globalization (1870–1913)" and contributor to "an increase in international trade that was unprecedented in hu ...
