Naval Aviation
Naval aviation / Aeronaval is the application of Military aviation, military air power by Navy, navies, whether from warships that embark aircraft, or land bases. It often involves ''navalised aircraft'', specifically designed for naval use. Seaborne aviation encompasses similar activities not restricted to navies, including marines and coast guards, such as in U.S. naval aviators. Naval aviation units are typically projected to a position nearer the target by way of an aircraft carrier. Carrier-based aircraft must be sturdy enough to withstand the demands of 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 wing, 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 Dogfight, air-to-air combat, surface warfare, surface ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rear Admiral
Rear admiral is a flag officer rank used by English-speaking navies. In most European navies, the equivalent rank is called counter admiral. Rear admiral is usually immediately senior to commodore and immediately below vice admiral. It is usually equivalent to the rank of major general in armies. In the U.S. Navy and some other navies, there are two rear admiral ranks. The term originated in the days of naval sailing squadrons and can trace its origins to the British Royal Navy. Each naval squadron was assigned an admiral as its head, who commanded from the centre vessel and directed the squadron's activities. The admiral would in turn be assisted by a vice admiral, who commanded the lead ships that bore the brunt of a battle. In the rear of the squadron, a third admiral commanded the remaining ships and, as this section was considered to be in the least danger, the admiral in command of it was typically the most junior. This has continued into the modern age, with rear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

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 of the United States, presid ...

Destroyer
In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or carrier battle group and defend them against a wide range of general threats. They were conceived 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 unatte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battleship
A battleship is a large, heavily naval armour, armored warship with a main battery consisting of large naval gun, guns, designed to serve as a capital ship. From their advent in the late 1880s, battleships were among the largest and most formidable weapon systems ever built, until they were surpassed by aircraft carriers beginning in the 1940s. The modern battleship traces its origin to the sailing ship of the line, which was developed into the steam ship of the line and soon thereafter the ironclad warship. After a period of extensive experimentation in the 1870s and 1880s, ironclad design was largely standardized by the British , which are usually referred to as the first "pre-dreadnought battleships". These ships carried an armament that usually included four large guns and several medium-caliber guns that were to be used against enemy battleships, and numerous small guns for self-defense. Naval powers around the world built dozens of pre-dreadnoughts in the 1890s and early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

As the junior officer in an infantry regiment was traditionally the carrier of the Military colours, standards and guidons, regimental colors, the rank acquired the name "ensign". This rank has generally been replaced in army ranks by second lieutenant.
