Sa'ar 5
Sa'ar 5 ( he, סַעַר, lit=storm) is a class of Israeli Navy corvettes. They were Israeli designed using lessons learned from the s. Three Sa'ar 5 ships were built by Huntington Ingalls Industries (formerly Litton-Ingalls Shipbuilding Corporation of Pascagoula, Mississippi) for the Israeli Navy, based on Israeli designs. They were the largest surface warships in Israel's naval fleet, although the Sa'ar 6-class corvette now being deployed are considerably larger. Although classified as "corvettes" due to their small size and crew of only 71, their weaponry and speed are almost comparable to that of a frigate. They are equipped with sonar, 2 triple torpedoes, 2 quadruple missile launchers, electronic warfare capabilities and decoys, a Close-in weapon system, 2 autocannon and a helipad and helicopter hangar. The first of class, , was launched in February 1993, followed by in August 1993 and in March 1994. Combat history On 14 July 2006 during the 2006 Lebanon War, INS ''Hanit ...

Corvette
A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper (or " rated") warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern roles that a corvette fulfills include coastal patrol craft, missile boat and fast attack craft. These corvettes are typically between 500 tons and 2,000 .although recent designs may approach 3,000 tons, having size and capabilities that overlap with smaller frigates. However unlike contemporary frigates, a modern corvette does not have sufficient endurance and seaworthiness for long voyages. The word "corvette" is first found in Middle French, a diminutive of the Dutch word ''corf'', meaning a "basket", from the Latin ''corbis''. The rank "corvette captain", equivalent in many navies to "lieutenant commander", derives from the name of this type of ship. The rank is the most junior of three "captain" ranks in sev ...

Israeli Navy
The Israeli Navy ( he, חיל הים הישראלי, ''Ḥeil HaYam HaYisraeli'' (English: The Israeli Sea Corps); ar, البحرية الإسرائيلية) is the naval warfare service arm of the Israel Defense Forces, operating primarily in the Mediterranean Sea theater as well as the Gulf of Eilat and the Red Sea theater. The current commander in chief of the Israeli Navy is Aluf David Sa'ar Salama. The Israeli Navy is believed to be responsible for maintaining Israel's offshore nuclear second strike capability. History The origins of the Israeli Navy lay in the founding of the Betar Naval Academy, a Jewish naval training school established in Civitavecchia, Italy, in 1934 by the Revisionist Zionist movement under the direction of Ze'ev Jabotinsky, The Academy trained cadets from all over Europe, Palestine and South Africa and produced some of the future commanders of the Israeli Navy. In September 1937, the training ship ''Sarah I'' visited Haifa and Tel Aviv as part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Class
A ship class is a group of ships of a similar design. This is distinct from a ship type, which might reflect a similarity of tonnage or intended use. For example, is a nuclear aircraft carrier (ship type) of the (ship class). In the course of building a class of ships, design changes might be implemented. In such a case, the ships of different design might not be considered of the same class; each variation would either be its own class, or a subclass of the original class (see for an example). If ships are built of a class whose production had been discontinued, a similar distinction might be made. Ships in a class often have names linked by a common factor: e.g. s' names all begin with T (, , ); and s are named after American battles (, , , ). Ships of the same class may be referred to as sister ships. Naval ship class naming conventions Overview The name of a naval ship class is most commonly the name of the lead ship, the first ship commissioned or built of its design. ...

Close-in Weapon System
A close-in weapon system (CIWS ) is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device. There are two types of CIWS systems. A gun-based CIWS usually consists of a combination of radars, computers, and rapid-firing multiple-barrel rotary cannons placed on a rotating turret. Missile-based CIWSs use either infra-red, passive radar/ ESM, or semi-active radar terminal guidance to guide missiles to the targeted enemy aircraft or other threats. In some cases, CIWS are used on land to protect military bases. In this case, the CIWS can also protect the base from shell and rocket fire. Gun systems A gun-based CIWS usually consists of a combination of radars, computers and rotary or revolver cannon placed on a rotating, automatically aimed gun mount. Example ...

Phalanx CIWS
The Phalanx CIWS (often spoken as "sea-wiz") is a gun-based close-in weapon system to defend military watercraft automatically against incoming threats such as aircraft, missiles, and small boats. It was designed and manufactured by the General Dynamics Corporation, Pomona Division,Thomas, Vincent C. ''The Almanac of Seapower 1987'' Navy League of the United States (1987) p.191 later a part of Raytheon. Consisting of a radar-guided Vulcan cannon mounted on a swiveling base, the Phalanx has been used by the United States Navy and the naval forces of 15 other countries. The US Navy deploys it on every class of surface combat ship, except the and . Other users include the British Royal Navy, the Royal Australian Navy, the Royal New Zealand Navy, the Royal Canadian Navy and the US Coast Guard (aboard its - and s).

Vertical Launching System
A vertical launching system (VLS) is an advanced system for holding and firing missiles on mobile naval platforms, such as surface ships and submarines. Each vertical launch system consists of a number of ''cells'', which can hold one or more missiles ready for firing. Typically, each cell can hold a number of different types of missiles, allowing the ship flexibility to load the best set for any given mission. Further, when new missiles are developed, they are typically fitted to the existing vertical launch systems of that nation, allowing existing ships to use new types of missiles without expensive rework. When the command is given, the missile flies straight up far enough to clear the cell and the ship, then turns on to the desired course. A VLS allows surface combatants to have a greater number of weapons ready for firing at any given time compared to older launching systems such as the Mark 13 single-arm and Mark 26 twin-arm launchers, which were fed from behind by a ...

Radar Warning Receiver
Radar warning receiver (RWR) systems detect the radio emissions of radar systems. Their primary purpose is to issue a warning when a radar signal that might be a threat is detected, like a fighter aircraft's fire control radar. The warning can then be used, manually or automatically, to evade the detected threat. RWR systems can be installed in all kind of airborne, sea-based, and ground-based assets such as aircraft, ships, automobiles, military bases. This article is focused mainly on airborne military RWR systems; for commercial police speed detection radar RWR systems, see radar detector. Depending on the market the RWR system is designed for, it can be as simple as detecting the presence of energy in a specific radar band, such as the frequencies of known surface-to-air missile systems. Modern RWR systems are often capable of classifying the source of the radar by the signal's strength, phase and signal details. The information about the signal's strength and waveform can t ...

Radio Jamming
Radio jamming is the deliberate jamming, blocking or interference with wireless communications.https://apps.fcc.gov/edocs_public/attachmatch/DA-12-347A1.pdf Enforcement Advisory No. 2012-02 FCC Enforcement Advisory Cell Jammers, GPS Jammers, and Other Jamming Devices Consumer Alert: Using or Importing Jammers is Illegal In some cases, jammers work by the transmission of radio signals that disrupt communications by decreasing the signal-to-noise ratio. The concept can be used in wireless data networks to disrupt information flow. It is a common form of censorship in totalitarian countries, in order to prevent foreign radio stations in border areas from reaching the country. Jamming is usually distinguished from interference that can occur due to device malfunctions or other accidental circumstances. Devices that simply cause interference are regulated differently. Unintentional "jamming" occurs when an operator transmits on a busy frequency without first checking whether it is in u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
