Restigouche-class Destroyer
The ''Restigouche''-class destroyer was a class of seven destroyer escorts that served the Royal Canadian Navy and later the Canadian Forces from the late-1950s to the late-1990s. All seven vessels in the class were named after rivers in Canada. The Royal Canadian Navy began planning the in the late 1940s and originally intended to procure fourteen vessels. Delays in design and construction saw the number of vessels for the ''St. Laurent'' class halved to seven. The seven remaining vessels were redesigned as the ''Restigouche'' class, taking into account design improvements found during construction of the ''St. Laurent''s. The seven ships of the class were commissioned between 1958 and 1959. Design and description Based on the preceding design, the ''Restigouche''s had the same hull and propulsion, but different weaponry.Gardiner and Chumbley, p. 45 Initially the ''St. Laurent'' class had been planned to be 14 ships. However the order was halved, and the following seven wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Vickers
Canadian Vickers Limited was an aircraft and shipbuilding company that operated in Canada from 1911 until 1944. A subsidiary of Vickers Limited, it built its own aircraft designs as well as others under licence. Canadair absorbed the Canadian Vickers aircraft operations in November 1944. Shipbuilding In 1907, British shipbuilding and weapons manufacturing conglomerate Vickers Sons & Maxim began investigating possible locations for a shipyard in Montreal.Linteau 1985, p. 84 Vickers Sons & Maxim intended to use the shipyard as a repair facility for transatlantic shipping traffic entering Montreal.Pritchard 2011, p. 51 Vickers Sons & Maxim was invited by the Government of Canada in 1911 to establish a Canadian division to manufacture vessels for the nascent Royal Canadian Navy. According to naval historian Marc Milner, "the Harbour Commission and the city of Maisonneuve offered Vickers a first-class location" to establish the yard, and "an extended lease on the land and defer ...

Sperry Corporation
Sperry Corporation was a major American equipment and electronics company whose existence spanned more than seven decades of the 20th century. Sperry ceased to exist in 1986 following a prolonged hostile takeover bid engineered by Burroughs Corporation, which merged the combined operation under the new name Unisys. Some of Sperry's former divisions became part of Honeywell, Lockheed Martin, Raytheon Technologies, and Northrop Grumman. The company is best known as the developer of the artificial horizon and a wide variety of other gyroscope-based aviation instruments like autopilots, bombsights, analog ballistics computers and gyro gunsights. In the post-WWII era the company branched out into electronics, both aviation-related, and later, computers. The company was founded by Elmer Ambrose Sperry. History Early history The company was incorporated on April 14 1910 by Elmer Ambrose Sperry as the Sperry Gyroscope Company, to manufacture navigation equipment—chief ...

Harpoon (missile)
The Harpoon is an all-weather, Over-the-horizon radar, over-the-horizon, anti-ship missile manufactured by McDonnell Douglas (now Boeing Defense, Space & Security). The Standoff Land Attack Missile , AGM-84E Standoff Land Attack Missile (SLAM) and later AGM-84H/K SLAM-ER (Standoff Land Attack Missile – Expanded Response) are cruise missile variants. The regular Harpoon uses active radar homing and flies just above the water to evade defenses. The missile can be launched from: * Fixed-wing aircraft (AGM-84), without the solid-fuel rocket Booster (rocketry), booster * warship, Surface ships (RGM-84), fitted with a solid-fuel rocket booster that detaches when expended, to allow the missile's main turbojet to maintain flight * Submarines (UGM-84), fitted with a solid-fuel rocket booster and encapsulated in a container to enable submerged launch through a torpedo tube * Coastal defense batteries (RGM-84), from which it would be fired with a solid-fuel rocket booster Development ...

Torpedoes
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially, a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called Naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant, surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships wi ...

Torpedo Launcher
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although torpedoes of other classes and diameters have been used. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within the submarine into the sea at the ambient pressure of the water ...

ASROC
The RUR-5 ASROC (for "Anti-Submarine Rocket") is an all-weather, all sea-conditions anti-submarine missile system. Developed by the United States Navy in the 1950s, it was deployed in the 1960s, updated in the 1990s, and eventually installed on over 200 USN surface ships, specifically cruisers, destroyers, and frigates. The ASROC has been deployed on scores of warships of many other navies, including Canada, Germany, Italy, Japan, Taiwan, Greece, Pakistan and others. History ASROC started development as the Rocket Assisted Torpedo (RAT) program by Naval Air Weapons Station China Lake in the early 1950s to develop a surface warship anti-submarine warfare (ASW) weapon to counter the new post-World War II submarines which ran quieter, at much higher speed and could attack from much longer range with high speed homing torpedoes. In addition, the goal was to take advantage of modern sonars with a much larger detection range. An extended range torpedo delivered by parachute from th ...

Limbo (weapon)
Limbo, or Anti Submarine Mortar Mark 10 (A/S Mk.10), was the final development of the forward-throwing anti-submarine weapon Squid, designed during the Second World War and was developed by the Admiralty Underwater Weapons Establishment in the 1950s. Limbo was installed on the quarterdeck of Royal Navy escort ships from 1955 to the mid-1980s, Australian-built destroyer and s. Limbo was widely employed by the Royal Canadian Navy, being incorporated into all destroyer designs from the late 1950s to the early 1970s, including the , , , and classes and the Type 12 President Class frigates built for the South African Navy in the 1960s. Operation Limbo was loaded and fired automatically with the crew under cover and was stabilised in pitch and roll. The firing distance of the mortars was controlled by opening gas vents; rounds could be fired from . The weapon was linked to the sonar system of the ship, firing on command when the target was in range. The rounds were projected so tha ...

3"/50 Caliber Gun
The 3-inch/50-caliber gun (spoken "three-inch fifty-caliber") in United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 50 Caliber (artillery), calibers long (barrel length is 3 in × 50 = ). Different guns (identified by Mark numbers) of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1900 through to 1990 on a variety of combatant and transport ship classes. The gun is still in use with the Spanish Navy on Serviola-class patrol boat, ''Serviola''-class patrol boats. Early low-angle guns The US Navy's first 3 inch /50-caliber gun (Mark 2) was an early model with a projectile velocity of per second. Low-angle (single-purpose/non-anti-aircraft) mountings for this gun had a range of 7000 yards at the maximum elevation of 15 degrees. The gun entered service around 1900 with the s, and was also fitted to s. By World War II these guns were found only on a few Coast Guard cutters and Defensively Equipped Mer ...

Vickers
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacturer, aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce Holdings, Rolls-Royce plc, which sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Platforms & Services, BAE Systems Land Systems.

3"/70 Mark 26 Gun
The 3"/70 Mark 26 Gun was a US post war naval anti-aircraft gun. Developed as a joint project with the United Kingdom, which called it the QF 3-inch Mark N1 gun, it had a water-cooled barrel combined with an automatic loader to deliver high rates of fire. The gun design was based on experience defending United States warships from Japanese kamikaze attacks in World War II and based on the 3-inch/50 caliber gun. The name indicates in US Navy terminology that this piece of naval artillery fires a projectile in diameter and has a barrel length of 70 calibers arrel length = 3" × 70 = "Mark 26" refers to the gun mounting rather than the gun itself. Due to the long development period, the gun did not enter service until 1956 and the mounts proved problematic; the gun was removed from most US warships after a short service life. The British mountings, known as Mark 6 in the Royal Navy, were to a different design and though also complex and subject to feed problems were more effec ...
