HMS Nautilus (1914)
HMS ''Nautilus'' was a Royal Navy submarine. She was the largest submarine built for the Royal Navy at the time. She was also the first to be given a name. ''Nautilus'' was designed in response to recommendations for an overseas submarine displacing 1,000 tons and capable of . The resulting design changed from the saddle tanks common at the time to a double hull. The order was given to Vickers in 1912 and her keel was laid down in March 1913. Although launched in 1914 it took until 1917 to complete the vessel. ''Nautilus'' spent most of her life with the 1st Submarine Flotilla at Portsmouth as a depot ship and later as a battery charging vessel. She was renamed N1 in June 1917. Following decommissioning she was sold for scrap to John Cashmore Ltd on 9 June 1922 and broken up at their yard at Newport, Wales.

Naval Ensign Of The United Kingdom
The White Ensign, at one time called the St George's Ensign due to the simultaneous existence of a cross-less version of the flag, is an ensign worn on British Royal Navy ships and shore establishments. It consists of a red St George's Cross on a white field, identical to the flag of England except with the Union Flag in the upper canton. The White Ensign is also worn by yachts of members of the Royal Yacht Squadron and by ships of Trinity House escorting the reigning monarch. In addition to the United Kingdom, several other nations have variants of the White Ensign with their own national flags in the canton, with the St George's Cross sometimes being replaced by a naval badge omitting the cross altogether. Yachts of the Royal Irish Yacht Club wear a white ensign with an Irish tricolour in the first quadrant and defaced by the crowned harp from the Heraldic Badge of Ireland.

Vickers Limited
Vickers Limited was a British engineering conglomerate. The business began in Sheffield in 1828 as a steel foundry and became known for its church bells, going on to make shafts and propellers for ships, armour plate and then artillery. Entire large ships, cars, tanks and torpedoes followed. Airships and aircraft were added, and Vickers jet airliners were to remain in production until 1965. Financial problems following the death of the Vickers brothers were resolved in 1927 by separating Metropolitan Carriage Wagon and Finance Company and Metropolitan-Vickers, then merging the remaining bulk of the original business with Armstrong Whitworth to form Vickers-Armstrongs. The Vickers name resurfaced as Vickers plc between 1977 and 1999. History Foundry Vickers was formed in Sheffield as a steel foundry by the miller Edward Vickers and his father-in-law George Naylor in 1828. Naylor was a partner in the foundry Naylor & Sanderson, and Vickers' brother William owned a steel roll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Cashmore Ltd
John Cashmore Ltd (also known as J Cashmore, or simply as Cashmore's or other derivations) was a company operating largely in Newport, Monmouthshire, Wales. It became best known for ship breaking and scrapping redundant British railway locomotives. History The company was founded in 1872 by a member of the Cashmore family in Horseley Heath, Staffordshire. While eventually the large part of the business was in Newport, with a business address at the Old Town Dock, the headquarters was in Great Bridge, Tipton. Scrapping of steam locomotives from the LMR, ER and WR, also took place at Gold's Hill, Great Bridge. The shipbreaking business was closed in October 1976, and the remaining business was incorporated into the Gynwed Group. Ship breaking It ran a ship breaking business on the banks of the River Usk, which had a very high tide enabling large vessels to be moved upstream. It scrapped many ex-Royal Navy ships including the following: * (Destroyer - 1914) * (Destroyer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newport, Wales
Newport ( cy, Casnewydd; ) is a city and Local government in Wales#Principal areas, county borough in Wales, situated on the River Usk close to its confluence with the Severn Estuary, northeast of Cardiff. With a population of 145,700 at the 2011 census, Newport is the third-largest authority with City status in the United Kingdom, city status in Wales, and seventh List of Welsh principal areas, most populous overall. Newport became a unitary authority in 1996 and forms part of the Cardiff-Newport metropolitan area. Newport was the site of the last large-scale armed insurrection in Great Britain, the Newport Rising of 1839. Newport has been a port since medieval times when the first Newport Castle was built by the Normans. The town outgrew the earlier Roman Britain, Roman town of Caerleon, immediately upstream and now part of the borough. Newport gained its first Municipal charter, charter in 1314. It grew significantly in the 19th century when its port became the focus of Coa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

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] |
Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Ancestry
An ancestor, also known as a forefather, fore-elder or a forebear, is a parent or (recursively) the parent of an antecedent (i.e., a grandparent, great-grandparent, great-great-grandparent and so forth). ''Ancestor'' is "any person from whom one is descended. In law, the person from whom an estate has been inherited." Two individuals have a genetic relationship if one is the ancestor of the other or if they share a common ancestor. In evolutionary theory, species which share an evolutionary ancestor are said to be of common descent. However, this concept of ancestry does not apply to some bacteria and other organisms capable of horizontal gene transfer. Some research suggests that the average person has twice as many female ancestors as male ancestors. This might have been due to the past prevalence of polygynous relations and female hypergamy. Assuming that all of an individual's ancestors are otherwise unrelated to each other, that individual has 2''n'' ancestors in the ...

Saddle Tank (submarine)
Saddle tanks are a type of ballast tank configuration fitted to submarines. Saddle tanks are fitted in pairs external to the pressure hull, one on each side, in a similar manner to that of a horse's saddle-bags, the positioning of which they resemble in appearance. Development The first effective submarines, those of World War I, had hulls that were broadly circular in cross-section, with a deck plate mounted midway. Their heavy battery tanks were mounted beneath this deck, for stability. The ballast tanks were mounted ''inside'' the pressure hull. For compactness the ballast tanks were wrapped around the batteries, low down and sharing the flat surfaces of the battery tank. The Kingston valves linking the ballast tanks to the sea could be left open, a practice known as "riding the valves", and the water level in the tanks controlled solely by the vent and blowing air valves. The drawback was that the ballast tanks, open to sea pressure, had a flat surface to the crew compartm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Hull
A double hull is a ship hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard, typically by a few feet, which forms a redundant barrier to seawater in case the outer hull is damaged and leaks. The space between the two hulls is sometimes used for storage of ballast water. Double hulls are a more extensive safety measure than double bottoms, which have two hull layers only in the bottom of the ship but not the sides. In low-energy collisions, double hulls can prevent flooding beyond the penetrated compartment. In high-energy collisions, however, the distance to the inner hull is not sufficient and the inner compartment is penetrated as well. Double hulls or double bottoms have been required in all passenger ships for decades as part of the Safety Of Life At Sea or SOLAS Convention. Uses Double hulls ...
