Motor Launch (naval)
A motor launch (ML) is a small military vessel in Royal Navy service. It was designed for harbour defence and submarine chasing. Similar vessels were used by the Royal Air Force for armed high-speed air-sea rescue. Some vessels for water police service are also known as motor launches. Motor launches were slower than motor torpedo boats and motor gun boats World War I service Although small by naval standards, it was larger than the preceding steam or diesel-engined harbour launches of 56 ft and coastal motor boats of 40 and 55 ft length. The first motor launches entered service in the First World War. These were five hundred and eighty vessels built by the US Elco company for the Admiralty, receiving the numbers ML-1 to ML-580. They served with the Royal Navy between 1916 and the end of the war, defending the British coast from German submarines. Some of the earliest examples, including ML 1, also served in the Persian Gulf from June 1916. After the Armistice ...

Electric Launch Company
The Electric Launch Company, later renamed Elco Motor Yachts ("Elco"), is an American boat building and electric motor company that has operated from 1893 to 1949 and from 1987 to the present. History Elco first made its mark at the World's Columbian Exposition of 1893 in Chicago. Fifty-five launches, each 36 feet long and powered by battery-driveelectric motors carried over a million passengers. In 1899 Isaac Rice, president of the Electric Storage Battery Company and owner of Electric Boat Company, now Electro-Dynamic Company, (both suppliers to Elco), acquired Elco as a subsidiary of his new Electric Boat Company. Elco built a new boatyard in Bayonne, New Jersey soon afterward. Previously, Elco boats had been built in subcontracted facilities. By 1900, electric-powered pleasure boats outnumbered the combined number of boats powered by steam and explosive engines (as gasoline-powered motors were called). By 1910, the advantages of the range and power of gasoline came to domi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Flotilla
A flotilla (from Spanish, meaning a small ''flota'' (fleet) of ships), or naval flotilla, is a formation of small warships that may be part of a larger fleet. Composition A flotilla is usually composed of a homogeneous group of the same class of warship, such as frigates, destroyers, torpedo boats, submarines, gunboats, or minesweepers. Groups of larger warships are usually called squadrons, but similar units of non-capital ships may be called squadrons in some instances, and flotillas in others. Formations including more than one capital ship, e.g. men-of-war, battleships, and aircraft carriers, typically alongside smaller ships and support craft, are typically called fleets, each portion led by a capital ship being a squadron or task force (see reference below). A flotilla is usually commanded by a rear admiral, a commodore or a captain, depending on the importance of the command (a vice admiral would normally command a squadron). A flotilla is often divided into two or ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Harbour Launch
The harbour launch was a type of small launch used by the Royal Navy for general duties around Royal Naval dockyards and sea ports. The first were built in the 1850s with the advent of the steam engine and were originally designated harbour service launches. From the 1890s to the 1960s they were built to the same common design, first with steam engines and later with diesel engines, by small yards contracted locally by dockyards and bases. In 1942, following the introduction of the Type Two 63 ft HSL by the Royal Air Force, Admiralty Fleet Order 1518 re-designated the harbour service launch as "Harbour Launch (Steam)" or "Harbour Launch (Diesel)", depending on the type of engine.

British Power Boat Company Type Two 63 Ft HSL
The Type Two HSL was a 63 ft high-speed launch craft made by British Power Boat Company (BPBC). The craft were used during the Second World War for air-sea rescue operations to save Allied aircrew from the sea. The Type Two superseded the 64 ft HSL, and was itself replaced by the Type Three 68 ft "Hants and Dorset" also built by the BPBC. The Type Two (aka Type 2) was nicknamed the "Whaleback" due to the distinctive curve to its deck and humped cabin. History The Type Two was designed in 1937 by George Selman, Chief Designer and Naval Architect of the British Power Boat Company, which was founded by Hubert Scott-Paine at Hythe. Scott-Paine had previously owned the Supermarine Aviation Company, later builders of the Supermarine Spitfire and several flying boat types. A low-set cabin contained the wheel-house, chart room and a sickbay. For defence against enemy aircraft, on top of the cabin were two aircraft-style turrets made by Armstrong-Whitworth initially with a single .3 ...

Anti-submarine
An anti-submarine weapon (ASW) is any one of a number of devices that are intended to act against a submarine and its crew, to destroy (sink) the vessel or reduce its capability as a weapon of war. In its simplest sense, an anti-submarine weapon is usually a projectile, missile or bomb that is optimized to destroy submarines. History Before World War I Prior to about 1890, naval weapons were only used against surface shipping. With the rise of the military submarine after this time, countermeasures were considered for use against them. The first submarine installation of torpedo tubes was in 1885 and the first ship was sunk by a submarine-launched torpedo in 1887. There were only two ways of countering the military submarine initially: ramming them or sinking them with gunfire. However, once they were submerged, they were largely immune until they had to surface again. By the start of the First World War there were nearly 300 submarines in service with another 80 in production ...

Fairmile B Motor Launch
The Fairmile Type-B motor launch was a type of motor launch (often referred to as MLs) built by British boatbuilder Fairmile Marine and others during the Second World War for the Royal Navy for coastal operations. Design While the Type A had been designed entirely by Fairmile, the Type B design had come from Bill Holt of the Admiralty based on the lines of a destroyer hull and the detailed design and production was taken on by Fairmile. Like all their designs it was based on total prefabrication so individual components could be contracted out to small factories for production and these arranged as kits that would be delivered to various boatyards for assembly and fitting out. Altogether approximately 650 boats were built between 1940 and 1945. Like the A Type, the B Type were initially intended as submarine chasers, so the boats were fitted with ASDIC (sonar) as standard. Their main armament initially reflected their anti-submarine focus, with 12 depth charges, a single QF 3 ...

Minelayer
A minelayer is any warship, submarine or military aircraft deploying explosive mines. Since World War I the term "minelayer" refers specifically to a naval ship used for deploying naval mines. "Mine planting" was the term for installing controlled mines at predetermined positions in connection with coastal fortifications or harbor approaches that would be detonated by shore control when a ship was fixed as being within the mine's effective range. Before World War I, mine ships were termed mine planters generally. For example, in an address to the United States Navy ships of Mine Squadron One at Portland, England, Admiral Sims used the term “mine layer” while the introduction speaks of the men assembled from the “mine planters”. During and after that war the term "mine planter" became particularly associated with defensive coastal fortifications. The term "minelayer" was applied to vessels deploying both defensive- and offensive mine barrages and large scale sea mining. " ...

Submarine Chaser
A submarine chaser or subchaser is a small naval vessel that is specifically intended for anti-submarine warfare. Many of the American submarine chasers used in World War I found their way to Allied nations by way of Lend-Lease in World War II. Submarine chaser variants U.S. Navy submarine chasers were designed specifically to destroy German submarines in World War I, and Japanese and German submarines in World War II. The small SC-1-class submarine chasers of the design used in World War I carried the hull designator SC (for Submarine Chaser). Their main weapon was the depth charge. They also carried machine guns and anti-aircraft guns. The similar-sized SC-497-class was built for World War II. Also in World War II, larger PC-461-class submarine chasers used the PC hull classification symbol (for Patrol, Coastal).Gardiner and Chesneau, pp. 71, 152-154 Class relationships: * 438 (98t, wooden hull) * 343 (450t, steel hull) * 68 (850t, steel hull) ** used in similar ro ...

Fairmile A Motor Launch
The Fairmile A motor launch was a type of motor launch designed by Fairmile Marine for the Royal Navy. Development Shortly before the Second World War the British industrialist Noel Macklin submitted to the Admiralty an innovative plan for the series production of a motor launch (vessels for harbour defence and submarine chasing). The design used prefabricated parts, which allowed various small concerns, such as furniture and piano manufacturers, to produce the individual components. These components could then be assembled in separate shipyards. The hull was to be made of double diagonal mahogany planking with plywood frames divided into nine watertight compartments. The Admiralty rejected the concept, and so the prototype was built as a private venture. In July 1939, two months before the outbreak of war, the Admiralty had a change of heart and awarded Macklin a contract to build eleven further Type A Fairmiles. Service The first vessel (ML100) was not completed until May 19 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
