Juneau Class Cruiser
The ''Juneau''-class cruisers were United States Navy light cruisers that were modified version of the design. The ships had the same dual-purpose main armament as with a much heavier secondary antiaircraft battery, while the anti-submarine depth charge tracks and torpedo tubes were removed along with a redesigned superstructure to reduce weight and increase stability. Three ships were ordered and built, all completed shortly after World War II, but only remained active long enough to see action during the Korean War. Redesign The s increased wartime complement and armament; and loss of ''Atlanta'' and ''Juneau'' (here referring to the ''Juneau'' of the ''Atlanta''-class, not to be confused with the lead ship of the ''Juneau''-class) revealed weaknesses in their stability and hull integrity of the ships which was addressed in a 1942 redesign at the same time as the modified , the . The ships had the same main armament as , but the bridge and superstructure were redesigned to r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Shipbuilding And Drydock Company
The Federal Shipbuilding and Drydock Company was a United States shipyard, active from 1917 to 1948. It was founded during World War I to build ships for the United States Shipping Board. During World War II, it built ships as part of the U.S. Government's Emergency Shipbuilding program. Operated by a subsidiary of the U.S. Steel, United States Steel Corporation, the shipyard was located at Kearny Point where the mouth of the Hackensack River meets Newark Bay in the Port of New York and New Jersey. The shipyard site is now part of River Terminal, a massive distribution facility that is partially a Foreign trade zones of the United States, foreign trade zone. Federal built numerous destroyers, destroyer escorts and a handful of light cruisers as well as merchant ships during and between the wars. Around 570 vessels were contracted for construction by Federal SB&DD Company with about 100 not delivered fully completed due to the end of the World War II. Federal also had a yard at Port ...

Armor Belt
Belt armor is a layer of heavy metal armor plated onto or within the outer hulls of warships, typically on battleships, battlecruisers and cruisers, and aircraft carriers. The belt armor is designed to prevent projectiles from penetrating to the heart of a warship. When struck by an artillery shell or underwater torpedo, the belt armor either absorbs the impact and explosion with its sheer thickness and strength, or else uses sloping to redirect the projectile and its blast downwards. Typically, the main armor belt covers the warship from its main deck down to some distance below the waterline. If, instead of forming the outer hull, the armor belt is built inside the hull, it is installed at a sloped angle for improved protection, as described above. The torpedo bulkhead Frequently, the main belt's armor plates were supplemented with a torpedo bulkhead spaced several meters behind the main belt, designed to maintain the ship's watertight integrity even if the main belt wa ...

Battle Of Chumonchin Chan
The Battle of Chumonchin Chan or the action of 2 July 1950 was the battle fought between surface combatants during the main phase of the Korean War. It began after an Allied flotilla encountered a Korean People's Navy supply fleet. Battle On 2 July 1950, , , and were sailing along the coast of the Sea of Japan The Sea of Japan is the marginal sea between the Japanese archipelago, Sakhalin, the Korean Peninsula, and the mainland of the Russian Far East.

Korean People's Navy
The Korean People's Army Naval Force (KPANF; Korean: 조선인민군 해군; Hanja: 朝鮮人民軍 海軍; ''Chosŏn-inmingun Haegun''; ) or the Korean People's Navy (KPN), is the naval service branch of the Korean People's Army, which contains each branch of the North Korean armed forces. There are some 780 vessels including 70 midget submarines (including the Yono-class submarine and Sang-O-class submarine), 20 Romeo-class submarines, and about 140 air cushioned landing craft. The North Korean navy is considered a brown-water (or riverine) navy and operates mainly within the 50 kilometer exclusion zone. The fleet consists of east and west coast squadrons, which cannot support each other in the event of war with South Korea. The limited range of its vessels means that, even in peacetime, it is virtually impossible for a ship on one coast to visit the other coast. History The KPN was established on 5 June 1946.

Anti-submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying naval mine, mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo#Classes and diameters, Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within t ...

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a s ...

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. Through their history they served in a variety of roles, primarily as convoy escorts and destroyer command ships, but also as scouts and fleet support vessels for battle fleets. Origins and development The first small steam-powered cruisers were built for the British Royal Navy with HMS ''Mercury'' launched in 1878. Such second and third class protected cruisers evolved, gradually becoming faster, better armed and better protected. Germany took a lead in small crui ...

Lifeboat (shipboard)
A lifeboat or liferaft is a small, rigid or inflatable boat carried for emergency evacuation in the event of a disaster aboard a ship. Lifeboat drills are required by law on larger commercial ships. Rafts (liferafts) are also used. In the military, a lifeboat may double as a whaleboat, dinghy, or gig. The ship's tenders of cruise ships often double as lifeboats. Recreational sailors usually carry inflatable liferafts, though a few prefer small proactive lifeboats that are harder to sink and can be sailed to safety. Inflatable lifeboats may be equipped with auto-inflation (carbon dioxide or nitrogen) canisters or mechanical pumps. A quick release and pressure release mechanism is fitted on ships so that the canister or pump automatically inflates the lifeboat, and the lifeboat breaks free of the sinking vessel. Commercial aircraft are also required to carry auto-inflating liferafts in case of an emergency water landing; offshore oil platforms also have liferafts. Ship-launche ...
