Holland 5
''Holland 5'' was the last of the five Holland-class submarine, ''Holland''-class submarines ordered by the British Admiralty to evaluate the potential of the submarine with the Royal Navy. She was one of the first submarines to be accepted into Royal Navy service, and unique to her class, she carried one of the earliest periscopes. By the time she was launched, a number of A class submarine (1903), A-class submarines had already been ordered to replace this class in navy service. She had a single-hull design, built from steel grades, "s" grade steel. She sank whilst under tow to the scrap yard in 1912, possibly caused by the torpedo hatch being left open. The wreck was rediscovered in 2000 and was designated under the Protection of Wrecks Act in 2005. The wreck is a Protected Wreck managed by Historic England. Damage has been caused to the site in recent years, and at some point between September 2008 and June 2010, the torpedo hatch was stolen off the wreck. Design and des ...

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. The Flag of the British Antarctic Territory and the Commissioners' flag of the Northern Lighthouse Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historic England
Historic England (officially the Historic Buildings and Monuments Commission for England) is an executive non-departmental public body of the British Government sponsored by the Department for Digital, Culture, Media and Sport. It is tasked with protecting the historic environment of England by preserving and listing historic buildings, scheduling ancient monuments, registering historic Parks and Gardens and by advising central and local government. The body was officially created by the National Heritage Act 1983, and operated from April 1984 to April 2015 under the name of English Heritage. In 2015, following the changes to English Heritage's structure that moved the protection of the National Heritage Collection into the voluntary sector in the English Heritage Trust, the body that remained was rebranded as Historic England. The body also inherited the Historic England Archive from the old English Heritage, and projects linked to the archive such as Britain from Above, w ...

Thames
The River Thames ( ), known alternatively in parts as the River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire, and flows into the North Sea near Tilbury, Essex and Gravesend, Kent, via the Thames Estuary. From the west it flows through Oxford (where it is sometimes called the Isis), Reading, Henley-on-Thames and Windsor. The Thames also drains the whole of Greater London. In August 2022, the source of the river moved five miles to beyond Somerford Keynes due to the heatwave in July 2022. The lower reaches of the river are called the Tideway, derived from its long tidal reach up to Teddington Lock. Its tidal section includes most of its London stretch and has a rise and fall of . From Oxford to the Estuary the Thames drops by 55 metres. Running through some of the drier parts of mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stokes Bay
Stokes Bay ( grid ref.:)) (50.782982, -1.163868) is an area of the Solent that lies just south of Gosport, between Portsmouth and Lee-on-the-Solent, Hampshire. There is a shingle beach with views of Ryde and East Cowes on the Isle of Wight to the south and Fawley to the south west. The settlement of Alverstoke is close by. History To the east of Stokes Bay is Fort Gilkicker, which was built in 1871 to guard the headland and the western approaches to Portsmouth Harbour and housed 22 gun emplacements. The bay was used for experiments with submarine mines from 1879-1912. A narrow gauge railway was built from the bay to Fort Blockhouse for these operations, along with a pier. Fort Gilkicker was used in both world wars to protect Portsmouth and air attacks and fell into disrepair shortly after 1945; it is on the Buildings at Risk Register and support is being sought for its conservation and for an alternative use. There was also a pier, adjacent to Gosport and Fareham Inshore R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reginald Bacon
Admiral Sir Reginald Hugh Spencer Bacon, (6 September 1863 – 9 June 1947) was an officer in the Royal Navy noted for his technical abilities. He was described by the First Sea Lord, Admiral Sir Jacky Fisher, as the man "acknowledged to be the cleverest officer in the Navy". Family Reginald was born at Wiggonholt in West Sussex, the son of the parish rector, Rev. Thomas Bacon, and his wife, Lavinia Emma, the daughter of George Shaw of Teignmouth in Devon. Rev. Thomas was the nephew of the industrialist, Anthony Bushby Bacon of Elcot Park in Berkshire and the grand-uncle of the historian, Emma Elizabeth Thoyts, of Sulhamstead House, also in Berkshire. Early career Reginald entered the Navy in 1877, qualified as a torpedo lieutenant, and first came to wider notice as commander of a flotilla of torpedo boats in the British naval manoeuvres of 1896. In 1897 he served as a member of the British punitive expedition to Benin, and on his return from active service wrote the book ''Be ...

HMS Holland 3
''Holland 3'' was a Royal Navy submarine launched on 9 May 1902. The submarine was designed by Vickers at Barrow-in-Furness and was laid down on 4 February 1901. The submarine was commissioned on 1 August 1902. ''Holland 3'' sank in trials in 1911 and was then sold on 7 October 1913. Service history In early August 1902 John Alfred Moreton was appointed to the submarine depot ship HMS ''Hazard'', to take command of HM Submarine No.3. Along with , she was one of the first two submarines to be accepted into Royal Navy The Royal Navy (RN) is the United Kingdom's naval warfare force.

Ballast Tank
A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural hogging or sagging stresses, or to increase draft, as in a semi-submersible vessel or platform, or a SWATH, to improve seakeeping. Using water in a tank provides easier weight adjustment than the stone or iron ballast used in older vessels, and makes it easy for the crew to reduce a vessel's draft when it enters shallower water, by temporarily pumping out ballast. Airships use ballast tanks mainly to control buoyancy and correct trim. History The basic concept behind the ballast tank can be seen in many forms of aquatic life, such as the blowfish or argonaut octopus. The concept has been invented and reinvented many times by humans to serve a variety of purpo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pressure Hull
A submarine hull has two major components, the ''light hull'' and the ''pressure hull''. The light hull (''casing'' in British usage) of a submarine is the outer non-watertight hull which provides a hydrodynamically efficient shape. The pressure hull is the inner hull of a submarine that maintains structural integrity with the difference between outside and inside pressure at depth. Shapes Modern submarines are usually cigar-shaped. This design, already visible on very early submarines, is called a "teardrop hull". It is structurally efficient for withstanding external pressure, and significantly reduces the hydrodynamic drag on the sub when submerged, but decreases the sea-keeping capabilities and increases drag while surfaced. History The concept of an outer hydrodynamically streamlined light hull separated from the inner pressure hull was first introduced in the early pioneering submarine Ictineo I designed by the Spanish inventor Narcís Monturiol in 1859. However, whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forth Bridge
The Forth Bridge is a cantilever railway bridge across the Firth of Forth in the east of Scotland, west of central Edinburgh. Completed in 1890, it is considered a symbol of Scotland (having been voted Scotland's greatest man-made wonder in 2016), and is a UNESCO World Heritage Site. It was designed by English engineers Sir John Fowler and Sir Benjamin Baker. It is sometimes referred to as the Forth Rail Bridge (to distinguish it from the adjacent Forth Road Bridge), although this has never been its official name. Construction of the bridge began in 1882 and it was opened on 4 March 1890 by the Duke of Rothesay, the future Edward VII. The bridge carries the Edinburgh–Aberdeen line across the Forth between the villages of South Queensferry and North Queensferry and has a total length of . When it opened it had the longest single cantilever bridge span in the world, until 1919 when the Quebec Bridge in Canada was completed. It continues to be the world's second-longest s ...

USS Holland (SS-1)
USS ''Holland'' (SS-1) was the United States Navy's first modern commissioned submarine, although not the first military submarine of the United States, which was the 1775 submersible ''Turtle''. The boat was originally laid down as ''Holland VI'' at the Crescent Shipyard of Elizabeth, New Jersey for John Philip Holland's Holland Torpedo Boat Company, and launched on 17 May 1897. She was acquired by the USN on 11 April 1900 and commissioned on 12 October 1900, Lieutenant H. H. Caldwell commanding.Friedman, p. 286 Design and construction ''Holland'' was built at former Navy Lieutenant Lewis Nixon's Crescent Shipyard of Elizabeth, New Jersey for John Holland's Holland Torpedo Boat Company, which became the Electric Boat company in 1899.

HMS A1
HMS ''A1'' was the Royal Navy's first British-designed submarine, and their first to suffer fatal casualties. She was the lead ship of the first British s and the only one to have a single bow torpedo tube. She was actually sunk twice: first in 1904 when she became the first submarine casualty, with the loss of all hands; however, she was recovered, but sank again in 1911, this time when she was unmanned. The wreck was discovered in 1989 and was designated under the Protection of Wrecks Act in 1998. The wreck is a Protected Wreck managed by Historic England. Design and construction She was an enlarged and improved – longer than the Royal Navy's five "Holland"-type boats. Subsequent A-class boats were even larger and differed from her in several respects. Like all members of her class, she was built at Vickers, Barrow-in-Furness. She was laid down on 19 February 1902 and launched on 9 July 1902. Before she left the yard she suffered from a hydrogen explosion. Later whil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
