General Purpose Frigate (Canada)
The General Purpose Frigate, or GPF, was a procurement project for the Royal Canadian Navy during the Cold War. The class was also known as the Tribal-class frigate. Intended as a replacement for the Second World War-era destroyers in service at the time, the frigate design was developed for the Progressive Conservative Diefenbaker government in the late 1950s as part of the general fleet renewal program. The GPF program was cancelled under the Liberal Pearson government as part of their plan to reshape the Canadian Armed Forces. Following the cancellation, a modified version of the design was used for the s. Background The Brock Report was released in 1961 and identified the need for a ship capable of replacing the s for the Royal Canadian Navy, especially their ability to provide naval gunfire support, along with being capable of carrying a helicopter. The need for further dedicated anti-submarine warfare (ASW) surface platforms was questioned due to the planned addition of su ...

Frigate
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), armoured frigates were developed as powerful ironclad warships, the term frigate was used because of their single gun deck. Later developments in ironclad ships rendered the frigate designation obsolete and the term fell out of favour. During the Second World War the name 'frigate' was reintroduced to des ...

Anti-submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instan ...

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 ...

Nuclear-powered Submarine
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. Nuclear submarines have considerable performance advantages over "conventional" (typically diesel-electric) submarines. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines. The large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods, and the long interval between refuelings grants a range virtually unlimited, making the only limits on voyage times being imposed by such factors as the need to restock food or other consumables. The limited energy stored in electric batteries means that even the most advanced conventional submarine can only remain submerged for a few days at slow speed, and only a few hours at top speed, though recent advances in air-independent propulsion have somewhat ameliorated this disadva ...

Guided Missile
In military terminology, a missile is a guided airborne ranged weapon capable of self-propelled flight usually by a jet engine or rocket motor. Missiles are thus also called guided missiles or guided rockets (when a previously unguided rocket is made guided). Missiles have five system components: targeting, guidance system, flight system, engine and warhead. Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles (ballistic, cruise, anti-ship, anti-submarine, anti-tank, etc.), surface-to-air missiles (and anti-ballistic), air-to-air missiles, and anti-satellite weapons. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Unguided jet- or rocket-propelled weapons are usually described as rocket artillery. Historically, the word ''missile'' referred to any projectile that is thrown, shot or propelled towards a target; this usage is ...

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 life ...

House Of Commons Of Canada
The House of Commons of Canada (french: Chambre des communes du Canada) is the lower house of the Parliament of Canada. Together with the Crown and the Senate of Canada, they comprise the bicameral legislature of Canada. The House of Commons is a democratically elected body whose members are known as members of Parliament (MPs). There have been 338 MPs since the most recent electoral district redistribution for the 2015 federal election, which saw the addition of 30 seats. Members are elected by simple plurality ("first-past-the-post" system) in each of the country's electoral districts, which are colloquially known as ''ridings''. MPs may hold office until Parliament is dissolved and serve for constitutionally limited terms of up to five years after an election. Historically, however, terms have ended before their expiry and the sitting government has typically dissolved parliament within four years of an election according to a long-standing convention. In any case, an ac ...

Suez Crisis
The Suez Crisis, or the Second Arab–Israeli war, also called the Tripartite Aggression ( ar, العدوان الثلاثي, Al-ʿUdwān aṯ-Ṯulāṯiyy) in the Arab world and the Sinai War in Israel,Also known as the Suez War or 1956 War; other names include the ''Sinai war'', ''Suez–Sinai war'', ''1956 Arab–Israeli war'', the Second Arab–Israeli war, ''Suez Campaign'', ''Sinai Campaign'', ''Kadesh Operation'' and ''Operation Musketeer'' was an invasion of Egypt in late 1956 by Israel, followed by the United Kingdom and France. The aims were to regain control of the Suez Canal for the Western powers and to remove Egyptian president Gamal Abdel Nasser, who had just swiftly nationalised the foreign-owned Suez Canal Company, which administered the canal. Israel's primary objective was to re-open the blocked Straits of Tiran. After the fighting had started, political pressure from the United States, the Soviet Union and the United Nations led to a withdrawal by the ...

F2H Banshee
The McDonnell F2H Banshee (company designation McDonnell Model 24) is an American single-seat carrier-based jet fighter aircraft deployed by the United States Navy and United States Marine Corps from 1948 to 1961. A development of the FH Phantom, it was one of the primary American fighters used during the Korean War, and was the only jet-powered fighter deployed by the Royal Canadian Navy.Mesko, 2002, p.48 The aircraft's name is derived from the banshee of Irish mythology. Design and development The Banshee was a development of the FH Phantom, and planning started before the Phantom entered production. McDonnell engineers intended the aircraft to be a modified Phantom that shared many parts with the earlier aircraft, but it soon became clear that the need for heavier armament, greater internal fuel capacity, and other improvements would make the idea infeasible.Mesko, 2002, p.10 The new aircraft would use much larger and more powerful engines, a pair of newly developed Westi ...
