Light Cruiser
A light cruiser is a type of small or medium-sized warship. The term is a shortening of the phrase "light armored cruiser", describing a small ship that carried armor in the same way as an armored cruiser: a protective belt and deck. Prior to this smaller cruisers had been of the protected cruiser model, possessing armored decks only. While lighter and smaller than other contemporary ships they were still true cruisers, retaining the extended radius of action and self-sufficiency to act independently around the world. Cruisers mounting larger guns and heavier armor relative to most light cruisers would come to be known as heavy cruisers, though the designation of 'light' versus 'heavy' cruisers would vary somewhat between navies. Through their history light cruisers served in a variety of roles, primarily on long-range detached patrol work, covering other military operations or global shipping lanes, as scouts and fleet support vessels for battle fleets, as destroyer command ship ...

Battle Of Leyte Gulf
The Battle of Leyte Gulf () 23–26 October 1944, was the largest naval battle of World War II and by some criteria the largest naval battle in history, with over 200,000 naval personnel involved. By late 1944, Japan possessed fewer capital ships (aircraft carriers and battleships) than the Allies of World War II, Allied forces had total aircraft carriers in the Pacific, which underscored the disparity in force strength at that point in the war. After the catastrophic Battle of the Philippine Sea in June 1944, senior Japanese military leaders understood that Japan's remaining naval forces were incapable of achieving a strategic victory against the Allies. However, the Japanese general staff believed that continuing to contest Allied offensives at sea was necessary, in order to both deter a future invasion of mainland Japan and to give the Japanese navy an opportunity to utilize its remaining strength. As a result, the Imperial Japanese Navy () mobilized nearly all of its remaini ... [...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] |

A navy, naval force, military maritime fleet, war navy, 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 a 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 na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
