SS Douglas (1858)
The first USS ''Gettysburg'' was a Steamship, steamer in the United States Navy. The ship was built in Glasgow, Scotland, in 1858, named Royal Mail Ship, RMS ''Douglas'', and operated by the Isle of Man Steam Packet Company in the United Kingdom between Liverpool, England, and Douglas, Isle of Man, Douglas on the Isle of Man until November 1862. She was then sold to Cunard, Wilson & Company on behalf of the Confederate agents Fraser, Trenholm & Company for use by the Confederate States of America during the American Civil War. Renamed ''Margaret and Jessie'', she operated as a blockade runner until her capture by the Union (American Civil War), Union on 5 November 1863. The ship then was Ship commissioning, commissioned into the Union Navy on 2 May 1864 as USS ''Gettysburg''. During her U.S. Navy service, ''Gettysburg'' operated with the North Atlantic Blockading Squadron, was involved in both the First Battle of Fort Fisher, first and Second Battle of Fort Fisher, second attacks ...

Douglas, Isle Of Man
Douglas (, ) is the Capital (political), capital city and largest settlement of the Isle of Man, with a population of 26,677 (2021) and an area of . It is located at the mouth of the River Douglas, Isle of Man, River Douglas, and on a sweeping bay of . The River Douglas forms part of the Douglas Harbour, city's harbour and main commercial port. Douglas was a small settlement until it grew rapidly as a result of links with the English port of Liverpool in the 18th century. Further population growth came in the following century, resulting during the 1860s in a staged transfer of the High Courts, the Lieutenant Governor's residence (actually located in nearby Onchan), and finally the seat of the legislature, Tynwald, to Douglas from the ancient capital, Castletown, Isle of Man, Castletown. The city is the island's main hub for business, finance, legal services, shipping, transport, shopping, and entertainment. The annual Isle of Man TT motorcycle races start and finish in Doug ...

Side-lever
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II. Reciprocating steam engines were progressively replaced in marine applications during the 20th century by steam turbines and marine diesel engines. History The first commercially successful steam engine was developed by Thomas Newcomen in 1712. The steam engine improvements brought forth by James Watt in the later half of the 18th century greatly improved steam engine efficiency and allowed more compact engine arrangements. Successful adaptation of the steam engine to marine applications in England would have to wait until almost a century after Newcomen, when Scottish engineer William Symington built the world's "first practical steamboat", the '' Charlotte Dundas'', in 1802.

Royal Mail Ship
Royal Mail Ship (sometimes Steam-ship or Steamer), usually seen in its abbreviated form RMS, is the ship prefix used for seagoing vessels that carry mail under contract to the British Royal Mail. The designation dates back to 1840. Any vessel designated as "RMS" has the right both to fly the pennant of the Royal Mail when sailing and to include the Royal Mail "crown" insignia with any identifying device and/or design for the ship.Royal Mails employees Courier newspaper page 20 August 2007 It was used by many shipping lines, but is often associated in particular with the White Star Line, Cunard, Royal Mail Lines, Union-Castle Line, Canadian Pacific Line, Orient Line and the P&OSNC, which held a number of high-profile mail contracts, and traditionally prefixed the names of many of their ships with the initials "RMS". While some lines in the past, particularly the Royal Mail Lines, called all their ships "RMS", technically a ship would use the prefix only while contracted to ...

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 19th century; 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 incorrectly 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 ...

Howitzers
The howitzer () is an artillery weapon that falls between a cannon (or field gun) and a mortar. It is capable of both low angle fire like a field gun and high angle fire like a mortar, given the distinction between low and high angle fire breaks at 45 degrees or 800 mils (NATO). With their long-range capabilities, howitzers can be used to great effect in a battery formation with other artillery pieces, such as long-barreled guns, mortars, and rocket artillery. Howitzers were valued for their ability to fire explosive shells and incendiary materials into fortifications. Unlike mortars, which had fixed firing angles, howitzers could be fired at various angles, providing greater flexibility in combat. Throughout the 18th and 19th centuries, howitzers evolved to become more mobile and versatile. The introduction of rifling in the mid-19th century led to significant changes in howitzer design and usage. By the early 20th century, howitzers were classified into different categori ...

Rifling
Rifling is the term for helical grooves machined into the internal surface of a firearms's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy. It is also the term (as a verb) for creating such grooves. The opposite of rifling is smoothbore. Rifling is measured in ''twist rate'', the distance the rifling takes to complete one full revolution, expressed as a ratio with 1 as its base (e.g., 1:). A shorter distance/lower ratio indicates a faster twist, generating a higher spin rate (and greater projectile stability). The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it: barrels intended for short, large-diameter projectiles such as spherical lead balls require a very low twist rate, such as 1 turn in 48 inches (122 cm). Barrels intended for long, small-diameter projectiles, such as the ultra-low-drag 80-grain 0.223 inch bullets (5.2 g, 5.56&nb ...

Parrott Rifle
The Parrott rifle was a type of muzzle-loading rifled artillery weapon used extensively in the American Civil War. Parrott rifle The gun was invented by Captain Robert Parker Parrott, a West Point graduate. He was an American soldier and inventor of military ordnance. He resigned from the service in 1836 and became the superintendent of the West Point Foundry in Cold Spring, New York. He created the first Parrott rifle (and corresponding projectile) in 1860 and patented it in 1861.. Daniel Treadwell, who developed a method for making built-up guns in the early 1840s, tried to claim that his patent infringed on an earlier one, but in 1866 United States District Court court dismissed it, deciding that Treadwell's claim was invalidated by a 1843 British patent to John Frith. Parrotts were manufactured with a combination of cast and wrought iron. The cast iron made for an accurate gun, but was brittle enough to suffer fractures. Hence, a large wrought iron reinforcing band was o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enlisted Personnel
An enlisted rank (also known as an enlisted grade or enlisted rate) is, in some armed services, any rank below that of a commissioned officer. The term can be inclusive of non-commissioned officers or warrant officers, except in United States military usage where warrant officers/chief warrant officers are a separate officer category ranking above enlisted grades and below commissioned officer grades. In most cases, enlisted service personnel perform jobs specific to their own occupational specialty, as opposed to the more generalized command responsibilities of commissioned officers. The term "enlistment" refers solely to a military commitment (whether officer or enlisted) whereas the terms "taken on strength" and "struck off strength" refer to a service member being carried on a given unit's roll. Canadian Armed Forces In the Canadian Armed Forces, the term non-commissioned member (NCM) is used. North Atlantic Treaty Organization For the ranks used by the North Atlantic Tr ...

Commissioned Officer
An officer is a person who holds a position of authority as a member of an armed force or uniformed service. Broadly speaking, "officer" means a commissioned officer, a non-commissioned officer (NCO), or a warrant officer. However, absent contextual qualification, the term typically refers only to a force's ''commissioned officers'', the more senior members who derive their authority from a commission from the head of state. Numbers The proportion of officers varies greatly. Commissioned officers typically make up between an eighth and a fifth of modern armed forces personnel. In 2013, officers were the senior 17% of the British armed forces, and the senior 13.7% of the French armed forces. In 2012, officers made up about 18% of the German armed forces, and about 17.2% of the United States armed forces. Historically armed forces have generally had much lower proportions of officers. During the First World War, fewer than 5% of British soldiers were officers (partly beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunboat
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies. History Pre-steam era In the age of sail, a gunboat was usually a small undecked vessel carrying a single smoothbore cannon in the bow, or just two or three such cannons. A gunboat could carry one or two masts or be oar-powered only, but the single-masted version of about length was most typical. Some types of gunboats carried two cannon, or else mounted a number of swivel guns on the railings. The small gunboat had advantages: if it only carried a single cannon, the boat could manoeuvre in shallow or restricted areas – such as rivers or lakes – where larger ships could sail only with difficulty. The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and quick to build, naval forces favoured swarm ...
