Commander
Commander (commonly abbreviated as Cmdr.) is a common naval officer rank. Commander is also used as a rank or title in other formal organizations, including several police forces. In several countries this naval rank is termed frigate captain. Commander is also a generic term for an officer commanding any armed forces unit, for example "platoon commander", "brigade commander" and "squadron commander". In the police, terms such as "borough commander" and "incident commander" are used. Commander as a naval and air force rank Commander is a rank used in navies but is very rarely used as a rank in armies. The title, originally "master and commander", originated in the 18th century to describe naval officers who commanded ships of war too large to be commanded by a lieutenant but too small to warrant the assignment of a post-captain and (before about 1770) a sailing master; the commanding officer served as his own master. In practice, these were usually unrated sloops-of-war of no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lieutenant Commander
Lieutenant commander (also hyphenated lieutenant-commander and abbreviated Lt Cdr, LtCdr. or LCDR) is a commissioned officer rank in many navies. The rank is superior to a lieutenant and subordinate to a commander. The corresponding rank in most armies and air forces is major, and in the Royal Air Force and other Commonwealth air forces is squadron leader. The NATO rank code is mostly OF-3. A lieutenant commander is a department officer or the executive officer ( second-in-command) on many warships and smaller shore installations, or the commanding officer of a smaller ship/installation. They are also department officers in naval aviation squadrons. Etymology Most Commonwealth and other navies address lieutenant commanders by their full rank or the positions they occupy ("captain" if in command of a vessel). The United States Navy, however, addresses officers by their full rank or the higher grade of the rank. For example, oral communications in formal and informal s ...

Versailles Peace Treaty
The Treaty of Versailles (french: Traité de Versailles; german: Versailler Vertrag, ) was the most important of the peace treaties of World War I. It ended the state of war between Germany and the Allied Powers. It was signed on 28 June 1919 in the Palace of Versailles, exactly five years after the assassination of Archduke Franz Ferdinand, which led to the war. The other Central Powers on the German side signed separate treaties. Although the armistice of 11 November 1918 ended the actual fighting, it took six months of Allied negotiations at the Paris Peace Conference to conclude the peace treaty. The treaty was registered by the Secretariat of the League of Nations on 21 October 1919. Of the many provisions in the treaty, one of the most important and controversial was: "The Allied and Associated Governments affirm and Germany accepts the responsibility of Germany and her allies for causing all the loss and damage to which the Allied and Associated Governments and thei ...

Naval Attaché
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water navy), open-ocean applications ( bl ...

Yokosuka Naval Air Group
The was the first aviation unit established by the Imperial Japanese Navy in 1916 and survived until the end of the Pacific War. It was charged with educating and training aviation personnel, practical testing of new aircraft, and tactical research. In the event of an emergency, it was supposed to take charge of the defense of Tokyo Bay, and from February 1944, when the war situation demanded it, the unit was also involved in combat. History The "Naval Aviation Research Committee", which was established in 1912, has laid the foundation for the Imperial Japanese Navy Air Service. With the start of domestic production of aircraft and training of crew members on track, the Air Corps Three Group Plan was established in 1916 in order to further improve aircraft. On 1 April 1916 the Yokosuka Naval Air Group was formed in Oppama, Yokosuka, Kanagawa Prefecture to replace the "Naval Aviation Research Committee". On 1 September 1923 the Great Kanto Earthquake caused great damage to facilit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Aviation
Naval aviation is the application of military air power by navies, whether from warships that embark aircraft, or land bases. Naval aviation is typically projected to a position nearer the target by way of an aircraft carrier. Carrier-based aircraft must be sturdy enough to withstand demanding carrier operations. They must be able to launch in a short distance and be sturdy and flexible enough to come to a sudden stop on a pitching flight deck; they typically have robust folding mechanisms that allow higher numbers of them to be stored in below-decks hangars and small spaces on flight decks. These aircraft are designed for many purposes, including air-to-air combat, surface attack, submarine attack, search and rescue, matériel transport, weather observation, reconnaissance and wide area command and control duties. Naval helicopters can be used for many of the same missions as fixed-wing aircraft while operating from aircraft carriers, helicopter carriers, destroyers and f ...

Battleship
A battleship is a large armored warship with a main battery consisting of large caliber guns. It dominated naval warfare in the late 19th and early 20th centuries. The term ''battleship'' came into use in the late 1880s to describe a type of ironclad warship,Stoll, J. ''Steaming in the Dark?'', Journal of Conflict Resolution Vol. 36 No. 2, June 1992. now referred to by historians as pre-dreadnought battleships. In 1906, the commissioning of into the United Kingdom's Royal Navy heralded a revolution in the field of battleship design. Subsequent battleship designs, influenced by HMS ''Dreadnought'', were referred to as "dreadnoughts", though the term eventually became obsolete as dreadnoughts became the only type of battleship in common use. Battleships were a symbol of naval dominance and national might, and for decades the battleship was a major factor in both diplomacy and military strategy.Sondhaus, L. ''Naval Warfare 1815–1914'', .

Ensign (rank)
Ensign (; Late Middle English, from Old French (), from Latin (plural)) is a junior rank of a commissioned officer in the armed forces of some countries, normally in the infantry or navy. As the junior officer in an infantry regiment was traditionally the carrier of the ensign flag, the rank acquired the name. This rank has generally been replaced in army ranks by second lieutenant. Ensigns were generally the lowest-ranking commissioned officer, except where the rank of subaltern existed. In contrast, the Arab rank of ensign, لواء, ''liwa''', derives from the command of units with an ensign, not the carrier of such a unit's ensign, and is today the equivalent of a major general. In Thomas Venn's 1672 ''Military and Maritime Discipline in Three Books'', the duties of ensigns are to include not only carrying the color but assisting the captain and lieutenant of a company and in their absence, have their authority. "Ensign" is ''enseigne'' in French, and ''chorąży'' in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
