Theodore D. Wilson
Theodore Delavan Wilson (also Theodore Delevan Wilson) (11 May 1840 – 29 June 1896) was an American naval ship designer, constructor and instructor of naval architecture and shipbuilding. As chief constructor for the Bureau of Construction and Repair from 1882 to 1892, he was in charge of all new warship design for the United States Navy. Through his efforts, the Navy began its transition out of a post–Civil War slump to become a modern naval power. Warships he designed include the pre-dreadnought battleship , whose destruction in Havana, Cuba, in 1898 precipitated the Spanish–American War. Life and career Born in New York City, Wilson apprenticed at the Brooklyn Navy Yard under Naval Constructor B.F. Delano. At the outbreak of the American Civil War, he volunteered for U.S. Army service and served as a non–commissioned officer in the 13th New York Regiment. Upon his return from the front in August 1861, he was transferred to the U.S. Navy and was appointed as a carpenter ... [...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 cannons, 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 ...

Protected Cruiser
Protected cruisers, a type of naval cruiser of the late-19th century, gained their description because an armoured deck offered protection for vital machine-spaces from fragments caused by shells exploding above them. Protected cruisers resembled armored cruisers, which had in addition a belt of armour along the sides. Evolution From the late 1850s, navies began to replace their fleets of wooden ships-of-the-line with armoured ironclad warships. However, the frigates and sloops which performed the missions of scouting, commerce raiding and trade protection remained unarmoured. For several decades, it proved difficult to design a ship which had a meaningful amount of protective armour but at the same time maintained the speed and range required of a "cruising warship". The first attempts to do so, armored cruisers like , proved unsatisfactory, generally lacking enough speed for their cruiser role. During the 1870s the increasing power of armour-piercing shells made armou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Advisory Board
The Naval Consulting Board, also known as the Naval Advisory Board (a name used in the 1880s for two previous committees), was a US Navy organization established in 1915 by Josephus Daniels, the Secretary of the Navy at the suggestion of Thomas Alva Edison. Daniels created the Board with membership drawn from eleven engineering and scientific organizations two years before the United States entered World War I to provide the country with the "machinery and facilities for utilizing the natural inventive genius of Americans to meet the new conditions of warfare." Daniels was concerned that the U.S. was unprepared for the new conditions of warfare and that they needed access to the newest technology. History Thomas Edison gave a speech in which he proposed a group of scientists should be involved with the World War I effort. In a statement issued in the ''New York Times'' on September 13, 1915, Josephus Daniels, the Secretary of the Navy asked Thomas Edison to be president of a ...

Rolling Mill
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes... Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock), bar stock, and rails. Most steel mills ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

CSS Virginia
CSS ''Virginia'' was the first steam-powered ironclad warship built by the Confederate States Navy during the first year of the American Civil War; she was constructed as a casemate ironclad using the razéed (cut down) original lower hull and engines of the scuttled steam frigate . ''Virginia'' was one of the participants in the Battle of Hampton Roads, opposing the Union's in March 1862. The battle is chiefly significant in naval history as the first battle between ironclads. USS ''Merrimack'' becomes CSS ''Virginia'' When the Commonwealth of Virginia seceded from the Union in 1861, one of the important federal military bases threatened was Gosport Navy Yard (now Norfolk Naval Shipyard) in Portsmouth, Virginia. Accordingly, orders were sent to destroy the base rather than allow it to fall into Confederate hands. On the afternoon of 17 April, the day Virginia seceded, Engineer in Chief B. F. Isherwood managed to get the frigate's engines lit. However, the previous night se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
