Hull Classification Symbol (Canada)
The Royal Canadian Navy uses hull classification symbols to identify the types of its ships, which are similar to the United States Navy's hull classification symbol system. The Royal Navy and some European and Commonwealth navies (19 in total) use a somewhat analogous system of pennant numbers. In a ship name such as the ship prefix HMCS for His or Her Majesty's Canadian Ship indicates the vessel is a warship in service to the Monarch of Canada, while the proper name ''Algonquin'' may follow a naming convention for the class of vessel. The hull classification symbol in the example is the parenthetical suffix (DDG 283), where the hull classification type DDG indicates that the ''Algonquin'' is a guided-missile destroyer and the hull classification number 283 is unique within that type. Listed below are various hull classification types with some currently in use and others that are retired and no longer in use. Auxiliary ships * AGOR: Auxiliary General Oceanographic Research ( ...

Royal Canadian Navy
The Royal Canadian Navy (RCN; french: Marine royale canadienne, ''MRC'') is the Navy, naval force of Canada. The RCN is one of three environmental commands within the Canadian Armed Forces. As of 2021, the RCN operates 12 frigates, four attack submarines, 12 coastal defence vessels, eight patrol class training vessels, two offshore patrol vessels, and several auxiliary vessels. The RCN consists of 8,570 Regular Force and 4,111 Primary Reserve sailors, supported by 3,800 civilians. Vice-Admiral Angus Topshee is the current commander of the Royal Canadian Navy and chief of the Naval Staff. Origins of the Royal Canadian Navy, Founded in 1910 as the Naval Service of Canada (French: ''Service naval du Canada'') and given royal sanction on 29 August 1911, the RCN was amalgamated with the Royal Canadian Air Force and the Canadian Army to form the Unification of the Canadian Forces, unified Canadian Armed Forces in 1968, after which it was known as Maritime Command (French: ''Commandemen ...

Sloop-of-war
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term ''sloop-of-war'' encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions. In World War I and World War II, the Royal Navy reused the term "sloop" for specialised convoy-defence vessels, including the of World War I and the highly successful of World War II, with anti-aircraft and anti-submarine capability. They performed similar duties to the American destroyer escort class ships, and also performed similar duties to the smaller corvettes of the Royal Navy.

Upholder/Victoria-class Submarine
The ''Upholder''/''Victoria''-class submarines, also known as the Type 2400 (due to their displacement of 2,400 tonnes), are the class of the diesel-electric submarines built in the United Kingdom in the 1980s to supplement the nuclear submarines in the Submarine Service of the British Royal Navy. The boats were originally named the ''Upholder'' class, after the most renowned vessel of the former U class. Their British service life was short, with the vessels being decommissioned in 1994. After an unsuccessful bid to transfer these submarines to the Pakistan Navy in 1993–1994, the Canadian government eventually purchased the submarines and a suite of trainers from the Royal Navy for Canadian Forces Maritime Command (renamed to Royal Canadian Navy in 2011) to replace their decommissioned s in 1998. In Canadian service, the submarines are classified as the ''Victoria'' class. These submarines initially suffered from serious electrical problems and were beset by mechanical ...

U And V-class Destroyer
The U and V class was a class of sixteen destroyers of the Royal Navy launched in 1942–1943. They were constructed in two flotillas, each with names beginning with "U-" or "V-" (although there was a return to the pre-war practice of naming the designated flotilla leader after a famous naval figure from history to honour the lost ships ''Grenville'' and ''Hardy''). The hull was nearly identical to the preceding ships of the S and T classes, but the U and V class ships had different bridge and armament fits. The flotillas constituted the 7th Emergency Flotilla and 8th Emergency Flotilla, built under the War Emergency Programme. These ships used the Fuze Keeping Clock HA Fire Control Computer. Notable actions Four ships, ''Verulam'', ''Venus'', ''Vigilant'' and ''Virago'', formed part of the 26th Destroyer Flotilla that ambushed and sank the , off Sumatra.

Escort Destroyer
An escort destroyer with United States Navy hull classification symbol DDE was a destroyer (DD) modified for and assigned to a fleet escort role after World War II. These destroyers retained their original hull numbers. Later, in March 1950, the post World War II ASW destroyer (DDK) classification was merged with the DDE classification, resulting in all DDK ships being reclassified as DDE, but again retaining their original hull numbers. On 30 June 1962, the DDE classification was retired, and all DDEs were reclassified as destroyers (DD). ''Escort destroyers'' should not be confused with the cheaper, slower, less capable, and more lightly armed World War II ''destroyer escorts''. Concept Following the outbreak of World War II, the Royal Navy had inadequate numbers of warships suitable for escort of trade convoys. While more modern destroyers were assigned to screen capital ships, destroyers built during World War I were modified to serve as trade convoy escorts. Four V and W- ...

Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Corvette
A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper (or " rated") warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern roles that a corvette fulfills include coastal patrol craft, missile boat and fast attack craft. These corvettes are typically between 500 tons and 2,000 .although recent designs may approach 3,000 tons, having size and capabilities that overlap with smaller frigates. However unlike contemporary frigates, a modern corvette does not have sufficient endurance and seaworthiness for long voyages. The word "corvette" is first found in Middle French, a diminutive of the Dutch word ''corf'', meaning a "basket", from the Latin ''corbis''. The rank "corvette captain", equivalent in many navies to "lieutenant commander", derives from the name of this type of ship. The rank is the most junior of three "captain" ranks in sev ...

YAG Training Vessels
YAG 300 (Yard Auxiliary, General) vessels were a series of ten wooden boats built between 1954 and 1955 that throughout their service acted as yard ferries (Blue Boats), training platforms and test beds for route survey equipment with the Royal Canadian Navy (RCN). Unofficially known as Canadian Forces Auxiliary Vessels (CFAV), the 75-foot boats primarily served as at-sea training platforms for junior naval officers, boatswains, reserve personnel and Sea Cadets at Canadian Forces Base (CFB) Esquimalt until they were taken out of service in 2007. According to the Department of National Defence, "in 2000, a total of 1830 personnel were deployed on the YAGs for a total of 585 days and steamed over 25,000 nautical miles (46,000 km) in support of training." Design and layout The boats were 75′ long overall, 18′6″ wide, had a draft of 4′6″, measured 70 tonnes, and were all powered by twin 6-71 Detroit Diesel engines. The boats were arranged in typical naval fashion with of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guided-missile Destroyer
A guided-missile destroyer (DDG) is a destroyer whose primary armament is guided missiles so they can provide anti-aircraft warfare screening for the fleet. The NATO standard designation for these vessels is DDG, while destroyers who have a primary gun armament and/or a small number of anti-aircraft missiles sufficient only for point-defense are designated DD. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing or dropping it altogether. Guided-missile destroyers are equipped with large missile magazines, with modern examples typically having vertical-launch cells. Some guided-missile destroyers contain integrated weapons systems, such as the United States’ Aegis Combat System, and may be adopted for use in an anti-missile or ballistic-missile defense role. This is especially true for navies that no longer operate cruisers, so other vessels must be adopted to fill in the gap. Many guided-missile destroyers are also multipurpo ...

United States Navy
The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States. It is the largest and most powerful navy in the world, with the estimated tonnage of its active battle fleet alone exceeding the next 13 navies combined, including 11 allies or partner nations of the United States as of 2015. It has the highest combined battle fleet tonnage (4,635,628 tonnes as of 2019) and the world's largest aircraft carrier fleet, with eleven in service, two new carriers under construction, and five other carriers planned.

Monarch Of Canada
The monarchy of Canada is Canada's form of government embodied by the Canadian sovereign and head of state. It is at the core of Canada's constitutional federal structure and Westminster-style parliamentary democracy. The monarchy is the foundation of the executive ( King-in-Council), legislative ( King-in-Parliament), and judicial ( King-on-the-Bench) branches of both federal and provincial jurisdictions. The king of Canada since 8 September 2022 has been Charles III. Although the person of the sovereign is shared with 14 other independent countries within the Commonwealth of Nations, each country's monarchy is separate and legally distinct. As a result, the current monarch is officially titled ''King of Canada'' and, in this capacity, he and other members of the royal family undertake public and private functions domestically and abroad as representatives of Canada. However, the monarch is the only member of the royal family with any constitutional role. The monarch lives ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
