Fire-control Radar
A fire-control radar (FCR) is a radar that is designed specifically to provide information (mainly target azimuth, elevation, range and range rate) to a fire-control system in order to direct weapons such that they hit a target. They are sometimes known as targeting radars, or in the UK, gun-laying radars. If the radar is used to guide a missile, it is often known as a target illuminator or illuminator radar. A typical fire-control radar emits a narrow, intense beam of radio waves to ensure accurate tracking information and to minimize the chance of losing track of the target. This makes them less suitable for initial detection of the target, and FCRs are often partnered with a medium-range search radar to fill this role. In British terminology, these medium-range systems were known as tactical control radars. Most modern radars have a track-while-scan capability, enabling them to function simultaneously as both fire-control radar and search radar. This works either by having t ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AN/SPQ-9
AN/SPQ-9A, (sometimes pronounced as "spook nine"), is a United States Navy multi-purpose surface search and fire control radar used with the Mk-86 gun fire-control system (MK86 GFCS). It is a two dimensional surface-search radar, meaning it provides only range and bearing but not elevation. It is intended primarily to detect and track targets at sea level, on the surface of the water for either gun fire engagement or navigation. It can however, also detect and track low altitude (below 2000 ft) air targets. Service Initially tested on the , it was also deployed on s, s, s, s, s, s, s, and National Security Cutters of the United States Coast Guard. It was fitted to the German Navy The German Navy (, ) is the navy of Germany and part of the unified ''Bundeswehr'' (Federal Defense), the German Armed Forces. The German Navy was originally known as the ''Bundesmarine'' (Federal Navy) from 1956 to 1995, when ''Deutsche Mari ...'s s as part of the Type 103B upgrade in the 198 ...

Aegis Combat 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 an ...

AN/SPG-62
The AN/SPG-62 is a continuous wave fire-control radar developed by the United States, and it is currently deployed on warships equipped with the Aegis Combat System. It provides terminal target illumination for the semi-active SM-2MR/ ER and ESSM Block 1 surface-to-air missiles. It also provides illumination for the active SM-6 if it is used in semi-active mode. The antenna is mechanically steered, uses a parabolic reflector, and operates at 8 to 12 GHz (I–J Band). The system is a component of the Mk 99 fire-control system (FCS). The first units were installed on the cruiser , which was commissioned in 1983. Since then, the SPG-62 has been placed in service with many U.S. and foreign navy ships that have the Aegis Combat System. The SPG-62's role in Aegis fire control is to illuminate targets in the terminal interception phase. First, the ship's main search radars—either the AN/SPY-1 or the AN/SPY-6—detect and track the target. The Mk 99 FCS then launches surface-to ...

RIM-66 Standard
The RIM-66 Standard MR (SM-1MR/SM-2MR) is a medium-range surface-to-air missile (SAM), with a secondary role as an anti-ship missile, originally developed for the United States Navy (USN). A member of the Standard Missile family of weapons, the SM-1 was developed as a replacement for the RIM-2 Terrier and RIM-24 Tartar that were deployed in the 1950s on a variety of USN ships. The RIM-67 Standard (SM-1ER/SM-2ER) is an extended range version of this missile with a solid rocket booster stage. Description The Standard missile program was started in 1963 to produce a family of missiles to replace existing guided missiles used by the Terrier, Talos, and Tartar guided missile systems. The intention was to produce a new generation of guided missiles that could be retrofit to existing guided missile systems. Standard Missile 1 The RIM-66A is the medium ranged version of the Standard missile and was initially developed as a replacement for the earlier RIM-24C as part of the Mk74 "Tarta ...

RIM-162 ESSM
The RIM-162 Evolved SeaSparrow Missile (ESSM) is a development of the RIM-7 Sea Sparrow missile used to protect ships from attacking missiles and aircraft. ESSM is designed to counter supersonic maneuvering anti-ship missiles. ESSM also has the ability to be "quad-packed" in the Mark 41 Vertical Launch System, allowing up to four ESSMs to be carried in a single cell. Design The original Sea Sparrow was an expedient design intended to provide short-range defensive fire in a system that could be deployed as rapidly as possible. The AIM-7 Sparrow was the simplest solution as its radar guidance allowed it to be fired head-on at targets and this guidance was easily provided by mounting an aircraft radar on a trainable platform. In the years after its introduction, it was upgraded to follow improvements being made in the air-to-air Sparrow models used by the US Navy and US Air Force. The ultimate version in this line of weapons was the R model, which introduced a new dual-seeker homing s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MIM-104 Patriot
The MIM-104 Patriot is a surface-to-air missile (SAM) system, the primary of its kind used by the United States Army and several allied states. It is manufactured by the U.S. defense contractor Raytheon and derives its name from the radar component of the weapon system. The AN/MPQ-53 at the heart of the system is known as the " Phased Array Tracking Radar to Intercept on Target", or PATRIOT. The Patriot system replaced the Nike Hercules system as the U.S. Army's primary High to Medium Air Defense (HIMAD) system and replaced the MIM-23 Hawk system as the U.S. Army's medium tactical air defense system. In addition to these roles, Patriot has been given the function of the U.S. Army's anti-ballistic missile (ABM) system, which is now Patriot's primary mission. The system is expected to stay fielded until at least 2040. Patriot uses an advanced aerial interceptor missile and high-performance radar systems. Patriot was developed at Redstone Arsenal in Huntsville, Alabama, which ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nike Missile
The United States Army's Nike Ajax was the world's first operational guided surface-to-air missile (SAM), entering service in 1954. Nike Ajax was designed to attack conventional bomber aircraft flying at high subsonic speeds and altitudes above . Nike was initially deployed in the US to provide defense against Soviet bomber attacks, and was later deployed overseas to protect US bases, as well as being sold to various allied forces. Some examples remained in use until the 1970s. Originally known simply as Nike, it gained the Ajax as part of a 1956 renaming effort that resulted from the introduction of Hercules. It was initially given the identifier SAM-A-7 (Surface-to-air, Army, design 7) as part of an early tri-service identification system, but later changed to MIM-3 (Mobile Interceptor Missile, design 3) in 1962.Nike was initially designated SAM-G-7, and later changed to SAM-A-7. Originally the Air Force used A while the Army used G, but the Air Force abandoned the 1947 tri-se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIM-23 Hawk
The Raytheon MIM-23 HAWK ("Homing all the way killer") is an American medium-range surface-to-air missile. It was designed to be a much more mobile counterpart to the MIM-14 Nike Hercules, trading off range and altitude capability for a much smaller size and weight. Its low-level performance was greatly improved over Nike through the adoption of new radars and a continuous wave semi-active radar homing guidance system. It entered service with the US Army in 1959. In 1971 it underwent a major improvement program as the Improved Hawk, or I-Hawk, which made several improvements to the missile and replaced all of the radar systems with new models. Improvements continued throughout the next twenty years, adding improved ECCM, a potential home-on-jam feature, and in 1995, a new warhead that made it capable against short-range tactical missiles. ''Jane's'' reported that the original system's single shot kill probability was 0.56; I-Hawk improved this to 0.85. Hawk was superseded b ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
