HMS Abercrombie (1915)
HMS ''Abercrombie'' was a First World War Royal Navy monitor. Background and construction On 3 November 1914, Charles M. Schwab of Bethlehem Steel offered Winston Churchill, then First Lord of the Admiralty, the use of four /45cal BL MK II twin gun turrets, originally destined for the Greek battleship . These turrets could not be delivered to the German builders, due to the British naval blockade. The Royal Navy immediately designed a class of monitors, designed for shore bombardment, to use the turrets. The ship was initially named ''Admiral Farragut'' in honour of the United States Admiral David Farragut, and reflecting the origin of the guns. She was laid down at the Harland and Wolff shipyard in Belfast on 12 December 1914. ''Farragut'' and ''General Grant'' were built together on the No 2 building berth, which had been constructed to build . The No 2 & 3 berths were beneath the Arrol Gantry, a large truss girder construction supporting modern electric cranes above t ...

First Lord Of The Admiralty
The First Lord of the Admiralty, or formally the Office of the First Lord of the Admiralty, was the political head of the English and later British Royal Navy. He was the government's senior adviser on all naval affairs, responsible for the direction and control of the Admiralty, and also of general administration of the Naval Service of the Kingdom of England, Great Britain in the 18th century, and then the United Kingdom, including the Royal Navy, the Royal Marines, and other services. It was one of the earliest known permanent government posts. Apart from being the political head of the Naval Service the post holder was simultaneously the pre-eminent member of the Board of Admiralty. The office of First Lord of the Admiralty existed from 1628 until it was abolished when the Admiralty, Air Ministry, Ministry of Defence, and War Office were all merged to form the new Ministry of Defence in 1964. Its modern-day equivalent is the Secretary of State for Defence. History In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of parts Part, parts or PART may refer to: People *Armi Pärt (born 1991), Estonian handballer * Arvo Pärt (born 1935), Estonian classical composer *Brian Part (born 1962), American child actor *Dealtry Charles Part (1882–1961), sheriff (1926–1927) a ..., which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, Fatigue (material), metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycling, recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking i ...

Aegean Sea
The Aegean Sea ; tr, Ege Denizi (Greek: Αιγαίο Πέλαγος: "Egéo Pélagos", Turkish: "Ege Denizi" or "Adalar Denizi") is an elongated embayment of the Mediterranean Sea between Europe and Asia. It is located between the Balkans and Anatolia, and covers an area of some 215,000 square kilometres. In the north, the Aegean is connected to the Marmara Sea and the Black Sea by the straits of the Dardanelles and the Bosphorus. The Aegean Islands are located within the sea and some bound it on its southern periphery, including Crete and Rhodes. The sea reaches a maximum depth of 2,639m to the west of Karpathos. The Thracian Sea and the Sea of Crete are main subdivisions of the Aegean Sea. The Aegean Islands can be divided into several island groups, including the Dodecanese, the Cyclades, the Sporades, the Saronic islands and the North Aegean Islands, as well as Crete and its surrounding islands. The Dodecanese, located to the southeast, includes the islands of R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coventry Ordnance Works
Coventry Ordnance Works was a British manufacturer of heavy guns particularly naval artillery jointly owned by Cammell Laird & Co of Sheffield and Birkenhead, Fairfield Shipbuilding and Engineering Company of Govan, Glasgow and John Brown & Company of Clydebank and Sheffield. Its core operations were from a 60-acre site in Stoney Stanton Road in the English city of Coventry, Warwickshire. At the end of 1918 it became a principal constituent of a brand new enterprise English Electric Company Limited. After World War II the works made electricity-generating machinery and heavy machine tools. History Consortium The company, the Coventry Ordnance Works Limited, was formed in July 1905 by a consortium of British shipbuilding firms John Brown 50%, Cammell Laird 25% and Fairfield 25% with the encouragement of the British government, which wanted a third major arms consortium to compete with the duopoly of Vickers Sons & Maxim and Sir W G Armstrong Whitworth & Co to drive down pric ...

Torpedo Bulge
The anti-torpedo bulge (also known as an anti-torpedo blister) is a form of defence against naval torpedoes occasionally employed in warship construction in the period between the First and Second World Wars. It involved fitting (or retrofitting) partially water-filled compartmentalized sponsons on either side of a ship's hull, intended to detonate torpedoes, absorb their explosions, and contain flooding to damaged areas within the bulges. Application Essentially, the bulge is a compartmentalized, below the waterline sponson isolated from the ship's internal volume. It is part air-filled, and part free-flooding. In theory, a torpedo strike will rupture and flood the bulge's outer air-filled component while the inner water-filled part dissipates the shock and absorbs explosive fragments, leaving the ship's main hull structurally intact. Transverse bulkheads within the bulge limit flooding to the damaged area of the structure. The bulge was developed by the British Director of ...

Truss Girder
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as ''nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for ...

Arrol Gantry
The Arrol Gantry was a large steel structure built by Sir William Arrol & Co. at the Harland and Wolff shipyard in Belfast, Ireland. It was built to act as overhead cranes for the building of the three ''Olympic''-class liners. Beardmore's gantry at Dalmuir From 1900 to 1906, Arrol had constructed a shipyard for William Beardmore and Company at Dalmuir on the Clyde. This included a large gantry structure over the building berth. In 1906 it was used for the construction of the pre-dreadnought battleship , then the largest battleship launched on the Clyde. The Beardmore gantry was long, wide and high, spanning a single building berth. The structure was of two long steel truss girders, supported on ten pairs of steel truss towers, braced by cross trusses above. Nine electric cranes were provided, with four jib cranes along each side girder, each having a 5-ton capacity and 30 foot jib. These were travelling cranes and could be moved along the girder, or grouped together to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Farragut
David Glasgow Farragut (; also spelled Glascoe; July 5, 1801 – August 14, 1870) was a flag officer of the United States Navy during the American Civil War. He was the first rear admiral, vice admiral, and admiral in the United States Navy. Farragut, 1879, p. 3 Hickman, 2010, p. 216 He is remembered for his order at the Battle of Mobile Bay, usually paraphrased as "Damn the torpedoes, full speed ahead" in U.S. Navy tradition. Stein, 2005, p. 5 Spears, 1905, p. 328 Born near Knoxville, Tennessee, Farragut was fostered by naval officer David Porter after the death of his mother. When he was 11 years old, Farragut served in the War of 1812 under the command of his adoptive father. He received his first command in 1823, at the age of 22, and went on to participate in anti-piracy operations in the Caribbean Sea. He then served in the Mexican–American War under the command of Matthew C. Perry, participating in the blockade of Tuxpan. After the war, he oversaw the construction ...

Naval Gun Support
Naval gunfire support (NGFS) (also known as shore bombardment) is the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range. NGFS is one of a number of disciplines encompassed by the term ''naval fires''. Modern naval gunfire support is one of the three main components of amphibious warfare assault operations support, along with aircraft and ship-launched land-attack missiles. Shipborne guns have been used against shore defences since medieval naval warfare. Tactics NGFS is classified into two types: direct fire, where the ship has line of sight with the target (either visually or through the use of radar), and indirect fire, which, to be accurate, requires an artillery observer to adjust fire. When on the gun line, ships are particularly vulnerable to attack from aircraft coming from a landward direction and flying low to avoid radar detection, or from submarines due to a predictable and steady (non-evasive) cour ...
