HMS Gallant (H59)
HMS ''Gallant'' (H59) was a G-class destroyer, built for the Royal Navy in the mid-1930s. During the Spanish Civil War of 1936–1939 the ship spent considerable time in Spanish waters, enforcing the arms blockade imposed by Britain and France on both sides of the conflict. ''Gallant'' was transferred from the Mediterranean Fleet shortly after the beginning of World War II to the British Isles, to escort shipping in local waters. She was slightly damaged by German aircraft during the evacuation of Allied troops from Dunkirk at the end of May 1940. Following repairs, ''Gallant'' was transferred to Gibraltar and served with Force H for several months. In November, the ship was transferred to the Mediterranean Fleet, where she escorted several convoys. She struck a mine in January 1941 and was towed to Malta for repairs. These were proved extensive and ''Gallant'' was further damaged by near-misses during an air raid in April 1942, before they were completed. The additional ...

Mediterranean Fleet
The British Mediterranean Fleet, also known as the Mediterranean Station, was a formation of the Royal Navy. The Fleet was one of the most prestigious commands in the navy for the majority of its history, defending the vital sea link between the United Kingdom and the majority of the British Empire in the Eastern Hemisphere. The first Commander-in-Chief for the Mediterranean Fleet was the appointment of General at Sea Robert Blake in September 1654 (styled as Commander of the Mediterranean Fleet). The Fleet was in existence until 1967. Pre-Second World War The Royal Navy gained a foothold in the Mediterranean Sea when Gibraltar was captured by the British in 1704 during the War of Spanish Succession, and formally allocated to Britain in the 1713 Treaty of Utrecht. Though the British had maintained a naval presence in the Mediterranean before, the capture of Gibraltar allowed the British to establish their first naval base there. The British also used Port Mahon, on the isla ... [...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 ...

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

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, 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, metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be 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 is sustainable, there are concerns about the use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries. In 2012, roughly 1,250 ocean ships were broken down, and their average age was ...

Scuttled
Scuttling is the deliberate sinking of a ship. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self-destruction to prevent the ship from being captured by an enemy force (or, in the case of a vessel engaged in illegal activities, by the authorities); as a blockship to restrict navigation through a channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers. Notable historical examples Skuldelev ships (around 1070) The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge. Cog near Kampen (early 15th century) In 2012, a cog preserved from the keel up to the decks in the silt was discovered alongside two smaller vessels in the river IJssel in t ...

Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individ ...

Malta Convoys
The Malta convoys were Allied supply convoys of the Second World War. The convoys took place during the Siege of Malta in the Mediterranean Theatre. Malta was a base from which British sea and air forces could attack ships carrying supplies from Europe to Italian Libya. Britain fought the Western Desert Campaign against Axis armies in North Africa to keep the Suez Canal and to control Middle Eastern oil. The strategic value of Malta was so great the British risked many merchant vessels and warships to supply the island and the Axis made determined efforts to neutralise the island as an offensive base. The civilian population and the garrison required imports of food, medical supplies, fuel and equipment; the military forces on the island needed reinforcements, ammunition and spare parts. British convoys were escorted to Malta by ships of the Mediterranean Fleet, Force H and aircraft of the Fleet Air Arm and Royal Air Force, during the Battle of the Mediterranean (1940–1 ...

Force H
Force H was a British naval formation during the Second World War. It was formed in 1940, to replace French naval power in the western Mediterranean removed by the French armistice with Nazi Germany. The force occupied an odd place within the naval chain of command. Normal British practice was to have naval stations and fleets around the world, whose commanders reported to the First Sea Lord via a flag officer. Force H was based at Gibraltar but there was already a flag officer at the base, Flag Officer Commanding, North Atlantic. The commanding officer of Force H did not report to this Flag Officer but directly to the First Sea Lord, Admiral of the Fleet Sir Dudley Pound. Operation Catapult One of the first operations that Force H took part in was connected with the reason for its formation. French naval power still existed in the Mediterranean, and the British Government viewed it as a threat to British interests. It was feared that the Vichy government of Philippe Pétain ...

Dunkirk Evacuation
The Dunkirk evacuation, codenamed Operation Dynamo and also known as the Miracle of Dunkirk, or just Dunkirk, was the evacuation of more than 338,000 Allied soldiers during the Second World War from the beaches and harbour of Dunkirk, in the north of France, between 26 May and 4 June 1940. The operation commenced after large numbers of Belgian, British, and French troops were cut off and surrounded by German troops during the six-week Battle of France. In a speech to the House of Commons, British Prime Minister Winston Churchill called this "a colossal military disaster", saying "the whole root and core and brain of the British Army" had been stranded at Dunkirk and seemed about to perish or be captured. In his "We shall fight on the beaches" speech on 4 June, he hailed their rescue as a "miracle of deliverance". After Germany invaded Poland in September 1939, France and the British Empire declared war on Germany and imposed an economic blockade. The British Expeditionary ...
