Noor (missile)
The Noor () is a long-range anti-ship missile, anti-ship cruise missile manufactured by Iran. The missile is in primary service with the Islamic Republic of Iran Navy, Iranian Navy. The missile is a Reverse engineering, reverse engineered Chinese YJ-83, C-802 anti-ship missile. History Iran was the first export customer of Chinese C-802 missiles. The contract was signed in 1995 but was cancelled due to U.S. pressure after 60 missiles had been delivered. After that, Iran started a program to reverse engineer the C-802. It is unknown when the programme was finished, but in 2000 and early 2001, Iran tested an upgraded C-802 missile during Unity-79 wargames. Officials said that the range of the missile is increased from . The missile is powered by Toloue-4, an Iranian version of the French Microturbo TRI 60 engine. In January 2004, Iran announced that it has started manufacturing the DM-3B mono pulse radar for the Noor missile. According to Iranian officials, DM-3B is a millim ...

Missile Boat Classes
A missile is an airborne ranged weapon capable of self-propelled flight aided usually by a propellant, jet engine or rocket motor. Historically, 'missile' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still recognized today with any unguided jet- or rocket-propelled weapons generally described as rocket artillery. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Missiles are also generally guided towards specific targets termed as guided missiles or guided rockets. Missile systems usually have five system components: targeting, guidance system, flight system, engine, and warhead. Missiles are primarily classified into different types based on firing source and target such as surface-to-surface, air-to-surface, surface-to-air and air-to-air missiles. Terminology Missile is derived from Latin "missilis" meaning "that may be thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nader Mahdavi
Nader Mahdavi () or Hossein Basria () was an Islamic Revolutionary Guard Corps naval commander who fought against United States naval forces and cruisers on 24 July 1987. Short biography Hossein Basria was born on 4 June 1963 in Nokar village, Dashti County, Bushehr Province. When he was in high school, economic issues and his political activities made him leave school and he started working in his father's store. After the Iranian revolution, he joined the Basij group. When Iran-Iraq war started, he wanted to go to battlefields but he was underage and was prevented from entering the war. On 20 April 1981, he was employed in the Islamic Revolutionary Guard Corps (IRGC). He married Sakineh Jokar in 1982. First battle with United States At the end of the Iran–Iraq War, the Persian Gulf was an unsafe place for Iranians, because Iraqi forces could easily bomb Iranian ships and oil platforms. Also, American naval forces protected Kuwaiti ships in the Persian Gulf and the Strait ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I-band
The NATO I band is the obsolete designation given to the radio frequencies from 8,000 to 10,000 MHz (equivalent to wavelengths between 3.75 and 3 cm) during the Cold War period. Since 1992, frequency allocations, allotment and assignments are in line with the NATO Joint Civil/Military Frequency Agreement __NOTOC__ The NATO Joint Civil/Military Frequency Agreement (NJFA) is the universal NATO common civil/military treaty to regulate the military access to the radio frequency spectrum in the range of 14 kHz to 100 GHz in peacetime, during ... (NJFA). However, in order to identify military radio spectrum requirements, e.g. for crisis management planning, training, electronic warfare activities, or in military operations, this system is still in use.

Surface Search Radar
A surface-search radar, sometimes more accurately known as a sea-surface-search radar or naval surveillance radar, is a type of military radar intended primarily to locate objects on the surface of lakes and oceans. Part of almost every modern naval ship, they are also widely used on maritime patrol aircraft and naval helicopters. When mounted on an aircraft, they are sometimes known, in British terminology, as air-to-surface-vessel radar — ASV for short. Similar radars are also widely used on civilian ships and even small pleasure craft, in which case they are more commonly known as marine radar. As with conventional surveillance radars, these systems detect objects from the reflections of radio signals off target objects, especially metal. The range of a surface-search radar is greatly increased compared to other roles due to several aspects of the sea surfaces and the objects in it. In low sea states, water makes an excellent reflector for radio signals, which helps maximize th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ZU-23-2
The ZU-23-2, also known as ZU-23, is a Soviet towed 23×152mm anti-aircraft twin-barreled autocannon. ZU stands for ''Zenitnaya Ustanovka'' (Russian: Зенитная Установка) – anti-aircraft mount. The GRAU index is 2A13. Development history The ZU-23-2 was developed in the late 1950s. It was designed to engage low-flying targets at a range of 2.5 km as well as armoured vehicles at a range of two kilometres and for direct defence of troops and strategic locations against air assault usually conducted by helicopters and low-flying airplanes. In 1955, KBP presented the single-barrel ZU-1 and the twin-barrel ZU-14. While the former was eventually dropped, the ZU-14 was selected and, after some modifications, entered series production. In the Soviet Union, some 140,000 units were produced. The ZU-23 has also been produced under licence by Bulgaria, Poland, Egypt and the People's Republic of China. Development of this weapon into a self-propelled anti-aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AK-230
The AK-230 is a Soviet radar-controlled 30mm naval anti-aircraft autocannon. It is mounted in an enclosed automatic turret and directed by radar. The AK-230 is widely used, mounted on large warships as well as small craft. About 1450 guns were produced in the USSR, and about 300 were produced in China as the Type 69. It was succeeded by the more powerful AK-630 from the mid-to-late 1970s. Development and service Development of the weapon began during the 1950s, with the first trial weapon fitted to the ''Osa'' class of fast attack missile boats and ''Shershen'' class torpedo boats. The weapon was officially accepted into service in 1969. Its service life was relatively short due to the fielding of the AK-630 system in the mid-1970s, which uses the same mountings and can be controlled by the same fire control systems. While its 30×210 mm round was much more powerful than the AK-630's 30×165 mm one, having the muzzle velocity of (the same as with 30×173 mm GA ...

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. Examples of ...

Active Radar Homing
Active radar homing (ARH) is a missile guidance method in which a missile contains a radar transceiver (in contrast to semi-active radar homing, which uses only a passive radar, receiver) and the electronics necessary for it to find and track its target autonomously. The NATO brevity code for an air-to-air active radar homing missile launch is fox (code word), Fox Three. Advantages There are two major advantages to active radar homing: * As the missile is tracking the target it is going to be much closer to the target than the launching platform during the terminal phase, thus the missile's tracking can be much more accurate and better resistant to electronic countermeasures. Active radar homing missiles have some of the best kill probability, kill probabilities, along with missiles employing track-via-missile guidance. * Because the missile is totally autonomous during the terminal phase, the launch platform does not need to have its radar enabled at all during this phase, an ...
