New Threat Upgrade
New Threat Upgrade (NTU) was a United States Navy program to improve and modernize the capability of existing cruisers and destroyers equipped with Terrier and Tartar anti-aircraft systems, keeping them in service longer. The Program was selected to install and test the Terrier New Threat Upgrade (NTU) Combat System with the improved Standard Missile Two Block II (Extended Range). Testing lasted from October 1981- March 1985. New Threat Upgrade allowed the full use of newer Standard missiles (SM-2ER BlkII w/Mk80 booster) and improved the interoperability of the radar, computer, tracking and engagement systems aboard the ships. The system allows the ships to which it was fitted to time share illumination radars for multiple missile interceptions in a manner similar the Aegis Combat System. History The New Threat Upgrade to the ''Leahy'' class included massive remodeling of the ship from food service space rehabilitation to a main propulsion system overhaul. Entire systems were ...

Aegis Weapon System
The Aegis Combat System is an American integrated naval weapons system developed by the Missile and Surface Radar Division of RCA, and it is now produced by Lockheed Martin. Initially used by the United States Navy, Aegis is now used also by the Japan Maritime Self-Defense Force, Spanish Navy, Royal Norwegian Navy, Republic of Korea Navy, and Royal Australian Navy, and is planned for use by the Royal Canadian Navy. As of 2022, a total of 110 Aegis-equipped ships have been deployed, and 71 more are planned (see operators). Aegis BMD (Ballistic Missile Defense) capabilities are being developed as part of the NATO missile defence system. Etymology The word "Aegis" is a reference that dates back to Greek mythology, with connotations of a protective shield, as the Aegis was the buckler (shield) of Zeus, worn by Athena. Overview The Aegis Combat System (ACS) is an advanced command and control (command and decision, or C&D, in Aegis parlance) system that uses powerful computers a ...

Virginia-class Cruiser
The ''Virginia'' class (also known as the CGN-38 class) were four nuclear-powered, guided-missile cruisers that served in the United States Navy until the mid-to-late 1990s. The double-ended cruisers (with missile armament carried both fore and aft) were commissioned between 1976 and 1980. They were the final class of nuclear-powered cruisers completed and the last ships ordered as Destroyer Leaders under the pre-1975 classification system. The ships had relatively short service lives. As nuclear-powered ships, they were expensive to operate. The class was coming up for their mid-life reactor refuelings when the 1994 Defense Authorization Bill was being formulated, which would effect cuts of 38% to the Navy's budget compared to the 1993 bill. The $300-million-plus cost of each refueling and other upgrades made the class easy targets for decommissioning. Each ship was therefore retired, starting with ''Texas'' in July 1993 and ending with ''Arkansas'' in 1998; all went through th ...

Leahy-class Cruiser
''Leahy''-class cruisers were a class of guided-missile cruisers built for the United States Navy. They were originally designated as Destroyer Leaders (DLG), but in the 1975 cruiser realignment they were reclassified as guided-missile cruisers (CG). They were a new "double-ender" class fitted with Terrier (later Standard ER) missile launchers fore and aft, and the first and only frigate class designed without a main gun battery for shore bombardment or ship-vs.-ship engagements—the gun armament was reduced in order to carry a larger missile load. One of the principal missions of these ships, like their predecessors the , was to form part of the anti-air and antisubmarine screen for carrier task forces, while also controlling aircraft from the carrier by providing vectors to assigned targets. The ships carried over the propulsion plant of the ''Farragut'' class, fitted into a longer hull designed with a knuckled “hurricane” bow that reduced plunging in a rough sea, thus ...

USS Mahan (DDG-42)
USS ''Mahan'' (DLG-11/DDG-42), was a guided missile destroyer in the United States Navy. She was named for Rear Admiral Alfred Thayer Mahan USN (1840–1914). The ship was laid down as DLG-11 by the San Francisco Naval Shipyard on 31 July 1957 and launched on 7 October 1959. ''Mahan'' was sponsored by Mrs. H. P. Smith, wife of Vice Adm. Harold Page Smith, and commissioned on 25 December 1960. ''Mahan'' was reclassified as a guided missile destroyer on 30 June 1975 and designated DDG-42. USS ''Mahan'' was decommissioned on 15 June 1993 and stricken from the Naval Vessel Register on the same day. History During the first year and a half of her commissioned service, ''Mahans primary assignment was the testing and evaluation of her weapons systems, RUR-5 ASROC and RIM-2 Terriers. A unit of the Pacific Fleet's Cruiser Destroyer Force, she operated out of San Diego, participating in local and fleet exercises off the west coast and in Hawaiian waters. Leaving San Diego on 6 Jun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farragut-class Destroyer (1958)
The ''Farragut''-class destroyer was a group of 10 guided-missile destroyers built for the United States Navy (USN) during the 1950s. They were the second destroyer class to be named for Admiral David Farragut. The class is sometimes referred to as the ''Coontz'' class, since ''Coontz'' was first to be designed and built as a guided-missile ship (under project SCB 142), whereas the previous three ships were designed as all-gun units (under SCB 129) and converted later.Friedman, pp. 295-297 The class was originally envisioned as a Destroyer Leader class (DL/DLG, verbally referred to as "Frigates"), but was reclassified as Guided-Missile Destroyers following the 1975 ship reclassification. Design and description The ''Farragut'' class was the first class of missile-armed carrier escorts to be built as such for the USN. The ships had an overall length of , a beam of and a deep draft of . They displaced at full load. Their crew consisted of 23 officers and 337 enlisted men.Fr ...

Charles F
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its ...

California-class Cruiser
The ''California'' class was a pair of nuclear-powered guided-missile cruisers operated by the United States Navy between 1974 and 1998. Other than their nuclear power supply and lack of helicopter hangars, ships of the ''California'' class were comparable to other guided-missile cruisers of their era, such as the . The class was built as a follow-up to the nuclear-powered , , and classes. Like all of the nuclear cruisers, which could steam for years between refuelings, the ''California'' class was designed in part to provide high endurance escort for the navy's nuclear aircraft carriers, which were often limited in range due to their conventionally powered escorts continuously needing to be refueled. Overview was the fourth nuclear-powered cruiser in the US Navy; the previous three were , , and . The second ''California''-class cruiser, , was the fifth nuclear-powered cruiser in the US Navy. Other than the four ships of the Soviet Navy's , which were built with a combina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belknap-class Cruiser
The ''Belknap''-class cruiser was a class of single-ended guided-missile cruisers (their missile armament was installed only forward, unlike "double-ended" missile cruisers with missile armament installed both forward and aft) built for the United States Navy during the 1960s. They were originally designated as DLG frigates (destroyer leaders; the USN use of the term frigate from 1950 to 1975 was intended to evoke the power of the sailing frigates of old), but in the 1975 fleet realignment, they were reclassified as guided missile cruisers (CG). Description When commissioned, the main armament of the ''Belknap'' class was a 5-inch/54-caliber Mk. 42 gun on the quarterdeck and a twin-rail RIM-2 Terrier Mk 10 Missile Launcher on the foredeck. The Mk 10 Mod 7 launchers in this class were also capable of launching RUR-5 ASROC to eliminate need for a separate Mk 112 ASROC launcher. These were unofficially spoken of as Ter/AS (tear-ass) launchers. The class was also equipped with two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mk 13 Missile Launcher
The Mark 13 guided missile launching system (GMLS) is a single-arm missile launcher designed for use on frigates and other military vessels. Because of its distinctive single-armed design, the Mark 13 is often referred to as the "one-armed bandit". The Mark 13 is equipped to fire the RIM-66 Standard, RGM-84 Harpoon, and RIM-24 Tartar missiles for anti-air and anti-ship defense, and is capable of firing the Standard at a rate of one every eight seconds. Its 40-round magazine consists of two concentric rings of vertically stored missiles, 24 in the outer ring and 16 in the inner. Total capacity was reduced by 1 due to a requirement to carry a Guided Missile Training Round (GMTR) in order to test system functionality. In case of a fire, the system is equipped with magazine sprinkling, CO2 suppression and booster suppression. It is also equipped with a dud jettison function to eject a round overboard if it fails to fire. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AN/SPG-51
The AN/SPG-51 is an American tracking / illumination fire-control radar for RIM-24 Tartar and RIM-66 Standard missiles. It is used for target tracking and Surface-to-air missile guidance on s, s, and s. The Italian Navy used it aboard their ''Audace'' class, ''Durand de la Penne'' class and s. The French ''Cassard'' class, Royal Netherlands Navy ''Tromp'' class and Spanish ''Baleares'' class frigates also use this system. Older variants were used on s, as well as the related German ''Lütjens'' class and ''Perth'' class used by the Royal Australian Navy. Aircraft tracking is based on monopulse radar utilizing Pulse-Doppler radar signal processing in MK 74 MOD 14 and MK 74 MOD 15. The MK 74 MOD 15 configuration includes continuous-wave radar tracking in addition to pulse-Doppler tracking. It provides illumination for bistatic radar operation associated with missile guidance in all configurations. Older systems rely on conical scanning Conical scanning is a system used i ...
