Oliver Hazard Perry Class
The ''Oliver Hazard Perry'' class is a class of guided-missile frigates named after U.S. Commodore Oliver Hazard Perry, the hero of the naval Battle of Lake Erie. Also known as the ''Perry'' or FFG-7 (commonly "fig seven") class, the warships were designed in the United States in the mid-1970s as general-purpose escort vessels inexpensive enough to be bought in large numbers to replace World War II-era destroyers and complement 1960s-era s. pp.42 In Admiral Elmo Zumwalt's "high low fleet plan", the FFG-7s were the low-capability ships, with the s serving as the high-capability ships. Intended to protect amphibious landing forces, supply and replenishment groups, and merchant convoys from aircraft and submarines. They were also later part of battleship-centered surface action groups and aircraft carrier battle groups/strike groups. 55 ships were built in the United States: 51 for the United States Navy and four for the Royal Australian Navy (RAN). Eight were built in Taiwan, six i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bath Iron Works
Bath Iron Works (BIW) is a major United States shipyard located on the Kennebec River in Bath, Maine, founded in 1884 as Bath Iron Works, Limited. Since 1995, Bath Iron Works has been a subsidiary of General Dynamics. It is the fifth-largest defense contractor in the world as of 2008. BIW has built private, commercial, and military vessels, most of which have been ordered by the United States Navy. History Bath Iron Works was incorporated in 1884 by General Thomas W. Hyde, a native of Bath who served in the American Civil War. After the war, he bought a shop that made windlasses and other iron hardware for the wooden ships built in Bath's many shipyards. He expanded the business by improving its practices, entering new markets, and acquiring other local businesses. By 1882, Hyde Windlass was eyeing the new and growing business of iron shipbuilding, and it incorporated as Bath Iron Works in 1884. On February 28, 1890, BIW won its first contract for complete vessels: two iron gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-ship Missile
An anti-ship missile (AShM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea skimming variety, and many use a combination of inertial guidance and active radar homing. A good number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. The first anti-ship missiles, which were developed and built by Nazi Germany, used radio command guidance.https://airandspace.si.edu/collection-objects/bomb-guided-fritz-x-x-1/nasm_A19840794000#:~:text=The%20Fritz%20X%2C%20also%20known,the%20Henschel%20Hs%20293%20missile. These saw some success in the Mediterranean Theatre during 1943–44, sinking or heavily damaging at least 31 ships with the Henschel Hs 293 and more than seven with the ''Fritz X'', including the Italian battleship ''Roma'' and the light cruiser . A variant of the HS 293 had a TV ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Airborne Multi-purpose System
The Light Airborne Multi-Purpose System (LAMPS) is the United States Navy's program that develops crewed helicopters to assist the surface fleet in anti-submarine warfare. The purpose of LAMPS is to scout outside the limits of a fleet's radar and sonar range to detect and track enemy submarines or missile-equipped escort ships and feed the real-time data back to their LAMPS mothership. They also have the capability to directly engage enemy targets with depth charges or torpedoes, or indirectly engage the enemy by coordinating fleet assets on site. A Mk II version was planned, but was canceled in favor of the more advanced Mk III. LAMPS III added the capabilities to use anti-ship missile systems (like the AGM-119 Penguin anti-ship missile) and night vision capability. History In October 1970, the UH-2 was selected to be the platform to function as the interim Light Airborne Multi-Purpose System (LAMPS) helicopter.Frawley 2002, p. 100. During the course of the 1960s, LAMP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cheng Kung-class Frigate
The ''Cheng Kung''-class frigates are eight guided-missile frigates in service in the Republic of China Navy (ROCN). They are based upon the U.S. and built by China Shipbuilding Corporation in Kaohsiung, Taiwan under license throughout the 1990s as part of the Kuang Hua I project. These frigates served as the mainstay of the ROCN's area air defense capability prior to the acquisition of the ''Keelung'' (''Kidd'')-class destroyers in 2005. They are designated with the hull classification PFG (Patrol Frigate, Guided missile) rather than FFG (Frigate, Guided missile) used by the ''Oliver Hazard Perry'' class. Background The Kwang Hua I project came out of renewed relations between the Republic of China and the United States following the election of President Ronald Reagan. Reagan's government took a harder stance with mainland China and began joint defense projects with the Taiwanese military. Among them was the Kwang Hua I project which was part of a series of new surface warships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hsiung Feng III
The Hsiung Feng III (HF-3; , "Brave Wind III") is a medium range supersonic missile with capabilities to destroy both land based targets and naval targets developed by the National Chung-Shan Institute of Science and Technology (NCSIST) in Taiwan. Design Initial prototype versions of the missile used the design of an integrated rocket ramjet to achieve supersonic speeds. It uses a solid fuel main booster with two side-by-side solid-propellant jettisonable strap-on rocket boosters for initial acceleration and a liquid-fueled ramjet for sustained cruise. It also employs electronic counter-countermeasures (ECCM) capabilities allowing it to penetrate an enemy ship's defenses. The missile is cylindrical in shape and composed of three sections, namely guidance and control, warhead, and propulsion. The body has four inlet ducts and four clipped delta control surfaces. It used the inertial navigation system (INS) during mid-course navigation phase and active radar seeker at terminal gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hsiung Feng II
The Hsiung Feng II (HF-2; , "Brave Wind II") is an anti-ship missile system developed by the National Chung-Shan Institute of Science and Technology (NCSIST) in Taiwan. The HF-2 is designed to be deployed aboard ships or at facilities on land. An airborne version has also been developed which can be carried by the ROC Air Force's F-CK fighters. The HF-2 has ECCM capabilities and is deployed on the ROC Navy's and frigates, as well as at several land-based sites. In 2000, plans were announced to replace the HF-2 missiles stationed on the Cheng Kung frigates with the RGM-84 Harpoon, but the budget for this was cancelled. Versions There are three major versions of HF-2 in service. he first to enter service is the ship-based HF-2, with 2 twin box launcher on destroyer DD-915 first as a trial vessel. Later all major surface combatant in RoCN, except the Knox, were equipped with 2 quad-launchers, plus the 7 World War II-era guided missile destroyers that was upgraded to WC ...

Otobreda 76 Mm
The OTO Melara 76 mm gun is a naval gun built and designed by the Italian defence company OTO Melara. It is based on the OTO Melara 76/62C and evolved toward 76/62 SR and 76/62 Strales. The system is compact enough to be installed on relatively small warships. Its high rate of fire and the availability of several types of ammunition make it capable of short-range anti-missile point defence, anti-aircraft, anti-surface, and ground support. Ammunition includes armour-piercing, incendiary, directed fragmentation effects, and a guided round marketed as capable of destroying manoeuvring anti-ship missiles. It can be installed in a stealth cupola. The OTO Melara 76 mm has been widely exported, and is in use by sixty navies. It was favoured over the French 100mm naval gun for the joint French/Italian project and FREMM frigate. On 27 September 2006 Iran announced it had started mass production of a naval gun named the Fajr-27, which is a reverse-engineered OTO Me ...

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

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] |
Mark 50 Torpedo
The Mark 50 torpedo is a U.S. Navy advanced lightweight torpedo for use against fast, deep-diving submarines. The Mk 50 can be launched from all anti-submarine aircraft and from torpedo tubes aboard surface combatant ships. The Mk 50 was intended to replace the Mk 46 as the fleet's lightweight torpedo. Instead the Mark 46 will be replaced with the Mark 54 LHT. The torpedo's stored chemical energy propulsion system uses a small tank of sulfur hexafluoride gas, which is sprayed over a block of solid lithium, which generates enormous quantities of heat, which generates steam. The steam propels the torpedo in a closed Rankine cycle, supplying power to a pump-jet. This propulsion system offers the very important deep-water performance advantage in that the combustion products—sulfur and lithium fluoride—occupy less volume than the reactants, so the torpedo does not have to force these out against increasing water pressure as it approaches a deep-diving submarine.

Mark 46 Torpedo
The Mark 46 torpedo is the backbone of the United States Navy's lightweight anti-submarine warfare torpedo inventory and is the NATO standard. These aerial torpedo An aerial torpedo (also known as an airborne torpedo or air-dropped torpedo) is a torpedo launched from a torpedo bomber aircraft into the water, after which the weapon propels itself to the target. First used in World War I, air-dropped torped ...es are designed to attack high-performance submarines. In 1989, an improvement program for the Mod 5 to the Mod 5A and Mod 5A(S) increased its shallow-water performance. The Mark 46 was initially developed as Research Torpedo Concept I (RETORC I), one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare.
