USS South Dakota (BB-57)
USS ''South Dakota'' (BB-57) was the lead vessel of the four fast battleships built for the United States Navy in the 1930s. The first American battleships designed after the Washington treaty system began to break down in the mid-1930s, the ''South Dakota''s were able to take advantage of a treaty clause that allowed them to increase the main battery to guns. However, congressional refusal to authorize larger battleships kept their displacement close to the Washington limit of . A requirement to be armored against the same caliber of guns as they carried, combined with the displacement restriction, resulted in cramped ships. Overcrowding was exacerbated by wartime modifications that considerably strengthened their anti-aircraft batteries and significantly increased their crews. ''South Dakota'' saw extensive action during World War II; immediately upon entering service in mid-1942, she was sent to the south Pacific to reinforce Allied forces waging the Guadalcanal campaig ...

Ammunition
Ammunition (informally ammo) is the material fired, scattered, dropped, or detonated from any weapon or weapon system. Ammunition is both expendable weapons (e.g., bombs, missiles, grenades, land mines) and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads). The purpose of ammunition is to project a force against a selected target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NATO) that enable their use across different weapo ...

Quonset Hut
A Quonset hut is a lightweight prefabricated structure of corrugated galvanized steel having a semi cylindrical cross-section. The design was developed in the United States, based on the Nissen hut introduced by the British during World War I. Hundreds of thousands were produced during World War II and military surplus was sold to the public. The name comes from the site of their first deployment at Quonset Point at the Davisville Naval Construction Battalion Center in Davisville, Rhode Island. Design and history The first Quonset huts were manufactured in 1941 when the United States Navy needed an all-purpose, lightweight building that could be shipped anywhere and assembled without skilled labor. The George A. Fuller construction company manufactured them, and the first was produced within 60 days of signing the contract. In 1946, the Great Lakes Steel Corporation claimed "the term 'Quonset,' as applied to builders and building materials, is a trade mark owned by the Grea ...

Sister Ship
A sister ship is a ship of the same class or of virtually identical design to another ship. Such vessels share a nearly identical hull and superstructure layout, similar size, and roughly comparable features and equipment. They often share a common naming theme, either being named after the same type of thing or person (places, constellations, heads of state) or with some kind of alliteration. Typically the ship class is named for the first ship of that class. Often, sisters become more differentiated during their service as their equipment (in the case of naval vessels, their armament) are separately altered. For instance, the U.S. warships , , , and are all sister ships, each being an . Perhaps the most famous sister ships were the White Star Line's s, consisting of , and . As with some other liners, the sisters worked as running mates. Other sister ships include the Royal Caribbean International's and . ''Half-sister'' refers to a ship of the same class but with some s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marianas Islands
The Mariana Islands (; also the Marianas; in Chamorro: ''Manislan Mariånas'') are a crescent-shaped archipelago comprising the summits of fifteen longitudinally oriented, mostly dormant volcanic mountains in the northwestern Pacific Ocean, between the 12th and 21st parallels north and along the 145th meridian east. They lie south-southeast of Japan, west-southwest of Hawaii, north of New Guinea and east of the Philippines, demarcating the Philippine Sea's eastern limit. They are found in the northern part of the western Oceanic sub-region of Micronesia, and are politically divided into two jurisdictions of the United States: the Commonwealth of the Northern Mariana Islands and, at the southern end of the chain, the territory of Guam. The islands were named after the influential Spanish queen Mariana of Austria following their colonization in the 17th century. The indigenous inhabitants are the Chamorro people. Archaeologists in 2013 reported findings which indicated that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Base Guam
Naval Base Guam is a strategic United States Navy#United States territories, U.S. naval base located on Apra Harbor and occupying the Orote Peninsula.

Asiatic-Pacific Theater
The Asiatic-Pacific Theater was the theater of operations of U.S. forces during World War II in the Pacific War during 1941–1945. From mid-1942 until the end of the war in 1945, two U.S. operational commands were in the Pacific. The Pacific Ocean Areas (POA), divided into the Central Pacific Area, the North Pacific Area and the South Pacific Area, were commanded by Fleet Admiral Chester W. Nimitz, Commander-in-Chief Pacific Ocean Areas. The South West Pacific Area (SWPA) was commanded by General of the Army Douglas MacArthur, Supreme Allied Commander South West Pacific Area. During 1945, the United States added the United States Strategic Air Forces in the Pacific, commanded by General Carl A. Spaatz. Because of the complementary roles of the United States Army and the United States Navy in conducting war, the Pacific Theater had no single Allied or U.S. commander (comparable to General of the Army Dwight D. Eisenhower in the European Theater of Operations). No actual comma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Barge
Barge nowadays generally refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but nowadays most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges. History of the barge Etymology "Barge" is attested from 1300, from Old French ''barge'', from Vulgar Latin ''barga''. The word originally could refer to any small boat; the modern meaning arose around 1480. ''Bark'' "small ship" is attested from 1420, from Old French ''barque'', from Vulgar Latin ''barca'' (400 AD). The more precise meaning of Barque as "three-masted sailing vessel" arose in the 17th century, and often takes the French spelling for disambiguation. Both are probably derived from the Latin ''barica'', from Greek ''baris'' "Egyptian boat", from Coptic ''bari'' "small boat", hieroglyphic Egyptian D58-G29-M17-M17-D21-P1 and similar ''b ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
