CSS Wasp
The ''Squib'' class torpedo boats were built for the Confederate States Navy during the later stages of the American Civil War. After the torpedo boat CSS ''David'' attacked and damaged the ironclad USS ''New Ironsides'', the Confederates continued building torpedo boats with hopes of breaking the Union blockade. Four vessels of the classCSS Hornet, CSS ''Hornet'', CSS Wasp, CSS ''Wasp'', CSS Squib, CSS ''Squib'', and CSS Scorpion, CSS ''Scorpion'' were constructed in Richmond, Virginia, in 1864. All were armed with a single spar torpedo and were powered by steam engines. ''Squib'' damaged the gunboat USS Minnesota (1855), USS ''Minnesota'' in an attack on April 9, 1864, and was later sent to Wilmington, North Carolina, where she was scuttled in February 1865. The other three vessels of the class were all part of the James River Squadron and participated in the Battle of Trent's Reach on the night of January 23 and 24, 1865. ''Scorpion'' ran aground during the battle, and w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo Boat
A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes. These were inshore craft created to counter both the threat of battleships and other slow and heavily armed ships by using speed, agility, and powerful torpedoes, and the overwhelming expense of building a like number of capital ships to counter an enemy's. A swarm of expendable torpedo boats attacking en masse could overwhelm a larger ship's ability to fight them off using its large but cumbersome guns. A fleet of torpedo boats could pose a similar threat to an adversary's capital ships, albeit only in the coastal areas to which their small size and limited fuel load restricted them. The introduction of fast torpedo boats in the late 19th century was a serious concern to the era's naval strategists, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Minnesota (1855)
USS ''Minnesota'' was a wooden steam frigate in the United States Navy. Launched in 1855 and commissioned eighteen months later, the ship served in east Asia for two years before being decommissioned. She was recommissioned at the outbreak of the American Civil War and returned to service as the flagship of the North Atlantic Blockading Squadron. During the first day of the Battle of Hampton Roads on 8 March 1862, ''Minnesota'' ran aground, and the following battle badly damaged her and inflicted many casualties. On the second day of the battle, engaged CSS ''Virginia'', allowing tugs to free ''Minnesota'' on the morning of 10 March. ''Minnesota'' was repaired and returned to duty, and three years later she participated in the Second Battle of Fort Fisher. ''Minnesota'' served until 1898, when she was stricken, beached and burnt to recover her metal fittings and to clear her name for a newly-ordered battleship, . Construction and early duties ] ''Minnesota'' was laid dow ... [...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 extremities 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 cor ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hull (ship)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. ...

Semi-submersible Naval Vessel
A semi-submersible naval vessel is a hybrid warship, that combines the properties of a surface ship and submarine by using water ballast to partially immerse and minimize its above-waterline profile, thereby improving its stealth characteristics when in hostile waters. The was an antecedent to such craft with its low-profile deck and gun turret. Russian and North Korean semi-submersible naval vessels evolved from torpedo boats and special forces boats that could partially submerge (sometimes to snorkel depth) to perform their missions. The US Navy SEALs use such vessels for clandestine special forces actions. Efforts to embody advantageous surface-ship characteristics into submarines have not been widely adopted. Antecedent USS ''Monitor'' was an iron-hulled, steam-powered warship—built during the American Civil War—as the first ironclad warship commissioned by the Union Navy. The ''Monitor'' is noted for its role in the Battle of Hampton Roads in 1862, when it fought indeci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lieutenant
A lieutenant ( , ; abbreviated Lt., Lt, LT, Lieut and similar) is a commissioned officer rank in the armed forces of many nations. The meaning of lieutenant differs in different militaries (see comparative military ranks), but it is often subdivided into senior (first lieutenant) and junior (second lieutenant and even third lieutenant) ranks. In navies, it is often equivalent to the army rank of captain; it may also indicate a particular post rather than a rank. The rank is also used in fire services, emergency medical services, security services and police forces. Lieutenant may also appear as part of a title used in various other organisations with a codified command structure. It often designates someone who is " second-in-command", and as such, may precede the name of the rank directly above it. For example, a "lieutenant master" is likely to be second-in-command to the "master" in an organisation using both ranks. Political uses include lieutenant governor in various g ...

Confederate States Of America
The Confederate States of America (CSA), commonly referred to as the Confederate States or the Confederacy was an unrecognized breakaway republic in the Southern United States that existed from February 8, 1861, to May 9, 1865. The Confederacy comprised U.S. states that declared secession and warred against the United States during the American Civil War: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, Texas, Virginia, Arkansas, Tennessee, and North Carolina. Kentucky and Missouri also declared secession and had full representation in the Confederate Congress, though their territory was largely controlled by Union forces. The Confederacy was formed on February 8, 1861, by seven slave states: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas. All seven were in the Deep South region of the United States, whose economy was heavily dependent upon agriculture—particularly cotton—and a plantation system that relied upon enslaved ...

Union (American Civil War)
During the American Civil War, the Union, also known as the North, referred to the United States led by President Abraham Lincoln. It was opposed by the secessionist Confederate States of America (CSA), informally called "the Confederacy" or "the South". The Union is named after its declared goal of preserving the United States as a constitutional union. "Union" is used in the U.S. Constitution to refer to the founding formation of the people, and to the states in union. In the context of the Civil War, it has also often been used as a synonym for "the northern states loyal to the United States government;" in this meaning, the Union consisted of 20 free states and five border states. The Union Army was a new formation comprising mostly state units, together with units from the regular U.S. Army. The border states were essential as a supply base for the Union invasion of the Confederacy, and Lincoln realized he could not win the war without control of them, especially Maryla ...

CSS Drewry
CSS ''Drewry'' was a gunboat of the Confederate States Navy during the American Civil War. This wooden gunboat had a foredeck protected by an iron V-shaped shield. Classed as a tender, she was attached to Flag Officer French Forrest's James River Squadron sometime in 1863 with Master Lewis Parrish, Confederate States Navy, CSN, in command. In addition to transporting troops and other routine service, she took part in several engagements along the river prior to January 24, 1865, when, in Trent's Reach, she was destroyed by two shots from a 100-pounder rifle in a battery of the 1st Connecticut Artillery. The second hit exploded her magazine as she assisted CSS Richmond, CSS ''Richmond'' to get afloat; all but two of her crew had reached safety before the explosion. Commanders The commanders of the CSS ''Drewry'' were:Coski * William Harwar Parker (May-fall 1862) * Master Lewis Parrish (around October 1863-May 1864) * Lieutenant William B. Hall (May 19-May 21, 1864) * Lieutenant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tender Ship
A ship's tender, usually referred to as a tender, is a boat, or a larger ship, used to service or support other boats or ships. This is generally done by transporting people or supplies to and from shore or another ship. A second and distinctly different meaning for ''tender'' is small boats carried by larger vessels, to be used either as lifeboats, or as transport to shore, or both. Tenders as smaller craft For a variety of reasons, it is not always advisable to try to tie a ship up at a dock; the weather or the sea might be rough, the time might be short, or the ship too large to fit. In such cases tenders provide the link from ship to shore, and may have a very busy schedule of back-and-forth trips while the ship is in port. On cruise ships, lifeboat tenders do double duty, serving as tenders in day-to-day activities, but fully equipped to act as lifeboats in an emergency. They are generally carried on davits just above the promenade deck, and may at first glance appear t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Trent's Reach
The Battle of Trent's Reach was one of the final major naval battles of the American Civil War. Beginning on January 23, 1865, a powerful flotilla of Confederate warships bombarded Fort Brady along the James River and engaged four Union Navy ships with the intention of breaking through the blockade to attack City Point, the base of General Ulysses S. Grant who was besieging Petersburg, Virginia. After two days of fighting, the rebels withdrew back up the river without completing their objectives. Background Confederate forces were under the direction of Commodore John K. Mitchell who commanded the James River Squadron in his flagship, the ironclad CSS ''Fredericksburg''. Weighing 700 tons, the ''Fredericksburg'' was a formidable opponent armed with one 11-inch smoothbore cannon and three smaller rifled guns. The ironclad rams CSS ''Richmond'' and CSS ''Virginia II'' also participated in the attack. ''Richmond'' weighed an estimated 800 tons and carried six guns. The ...
