Squadron (naval)
A squadron, or naval squadron, is a significant group of warships which is nonetheless considered too small to be designated a fleet. A squadron is typically a part of a fleet. Between different navies there are no clear defining parameters to distinguish a squadron from a fleet (or from a flotilla), and the size and strength of a naval squadron varies greatly according to the country and time period. Groups of small warships, or small groups of major warships, might instead be designated flotillas by some navies according to their terminology. Since the size of a naval squadron varies greatly, the rank associated with command of a squadron also varies greatly. Before 1864 the entire fleet of the Royal Navy was divided into three squadrons, the red, the white, and the blue. Each Royal Navy squadron alone was more powerful than most national navies. Today, a squadron might number three to ten vessels, which might be major warships, transport ships, submarines, or small craft i ...

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 ...

Kure Naval District
was the second of four main administrative districts of the pre-war Imperial Japanese Navy. Its territory included the Seto Inland Sea, Inland Sea of Japan and the Pacific Ocean, Pacific coasts of southern Honshū from Wakayama prefecture, Wakayama to Yamaguchi prefectures, eastern and northern Kyūshū and Shikoku. The area of the Kure Naval District encompassed Hashirajima Anchoring Area located at the south end of Hiroshima Bay, 30-40 kilometers southwest of Kure. When not in need of repairs ships usually anchored in this area to free up pier space at Kure. Hashirajima was also a major staging area for fleet operations. Tokuyama, Yamaguchi, Tokuyama port, was also part of Kure Naval District, and had the largest fuel depot in the Japanese Navy. History The location of Kure, Hiroshima, Kure within the sheltered Inland Sea of Japan was recognized of strategic importance in controlling the sea lanes around western Japan by the Meiji government and early Imperial Japanese Navy.

Submarine Tender
A submarine tender is a type of depot ship that supplies and supports submarines. Development Submarines are small compared to most oceangoing vessels, and generally do not have the ability to carry large amounts of food, fuel, torpedoes, and other supplies, nor to carry a full array of maintenance equipment and personnel. The tender carries all these, and either meets submarines at sea to replenish them or provides these services while docked at a port near the area where the submarines are operating. In some navies, the tenders were equipped with workshops for maintenance, and as floating dormitories with relief crews. With the increased size and automation of modern submarines, plus in some navies the introduction of nuclear power, tenders are no longer as necessary for fuel as they once were. Canada Canada's first Submarine Depot Ship was . Chile The term used in the Chilean Navy is "submarine mother ship", as for example the BMS (buque madre de submarinos) ''Almirante M ...

Executive Officer
An executive officer is a person who is principally responsible for leading all or part of an organization, although the exact nature of the role varies depending on the organization. In many militaries and police forces, an executive officer, or "XO", is the second-in-command, reporting to the commanding officer. The XO is typically responsible for the management of day-to-day activities, freeing the commander to concentrate on strategy and planning the unit's next move. Administrative law While there is no clear line between principal executive officers and inferior executive officers, principal officers are high-level officials in the executive branch of U.S. government such as department heads of independent agencies. In ''Humphrey's Executor v. United States'', 295 U.S. 602 (1935), the Court distinguished between executive officers and quasi-legislative or quasi-judicial officers by stating that the former serve at the pleasure of the president and may be removed at their di ...

Lieutenant
A lieutenant ( , ; abbreviated Lt., Lt, LT, Lieut and similar) is a commissioned officer rank in the armed forces of many nations. The meaning of lieutenant differs in different militaries (see comparative military ranks), but it is often subdivided into senior (first lieutenant) and junior (second lieutenant and even third lieutenant) ranks. In navies, it is often equivalent to the army rank of captain; it may also indicate a particular post rather than a rank. The rank is also used in fire services, emergency medical services, security services and police forces. Lieutenant may also appear as part of a title used in various other organisations with a codified command structure. It often designates someone who is " second-in-command", and as such, may precede the name of the rank directly above it. For example, a "lieutenant master" is likely to be second-in-command to the "master" in an organisation using both ranks. Political uses include lieutenant governor in various g ...

Naval Artillery
Naval artillery is artillery mounted on a warship, originally used only for naval warfare and then subsequently used for naval gunfire support, shore bombardment and anti-aircraft roles. The term generally refers to tube-launched projectile-firing weapons and excludes self-propelled projectiles such as torpedoes, rockets, and missiles and those simply dropped overboard such as depth charges and naval mines. Origins The idea of ship-borne artillery dates back to the classical era. Julius Caesar indicates the use of ship-borne catapults against Britons ashore in his ''Commentarii de Bello Gallico''. The dromons of the Byzantine Empire carried catapults and Greek fire, fire-throwers. From the late Middle Ages onwards, warships began to carry cannon, cannons of various calibres. The Mongol invasion of Java introduced cannons to be used in naval warfare (e.g. Cetbang by the Majapahit). The Battle of Arnemuiden, fought between England and France in 1338 at the start of the Hundred Y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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'', .

Midshipman
A midshipman is an officer of the lowest rank, in the Royal Navy, United States Navy, and many Commonwealth navies. Commonwealth countries which use the rank include Canada (Naval Cadet), Australia, Bangladesh, Namibia, New Zealand, South Africa, India, Pakistan, Singapore, Sri Lanka, and Kenya. In the 17th century, a midshipman was a rating for an experienced seaman, and the word derives from the area aboard a ship, amidships, either where he worked on the ship, or where he was berthed. Beginning in the 18th century, a commissioned officer candidate was rated as a midshipman, and the seaman rating began to slowly die out. By the Napoleonic era (1793–1815), a midshipman was an apprentice officer who had previously served at least three years as a volunteer, officer's servant or able seaman, and was roughly equivalent to a present-day petty officer in rank and responsibilities. After serving at least three years as a midshipman or master's mate, he was eligible to take the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Japanese Naval Academy
The was a school established to train line officers for the Imperial Japanese Navy. It was originally located in Nagasaki, moved to Yokohama in 1866, and was relocated to Tsukiji, Tokyo in 1869. It moved to Etajima, Hiroshima in 1888. Students studied for three or four years, and upon graduation were ordered (warranted) as Midshipmen, commissioned to the rank of Ensign/ Acting Sub-Lieutenant after a period of active duty and an overseas cruise. In 1943, a separate school for naval aviation was opened in Iwakuni, and in 1944, another naval aviation school was established in Maizuru. The Academy was closed in 1945, when the Imperial Japanese Navy was abolished. The Naval Academy Etajima opened in 1956 and the site now serves as the location for Officer Candidate School of the Japan Maritime Self-Defense Force.
