AGM-88
The AGM-88 HARM (High-speed Anti-Radiation Missile) is a tactical, air-to-surface missile, air-to-surface anti-radiation missile designed to home in on electronic transmissions coming from surface-to-air radar systems. It was originally developed by Texas Instruments as a replacement for the AGM-45 Shrike and AGM-78 Standard ARM system. Production was later taken over by Raytheon Corporation when it purchased the defense production business of Texas Instruments. Description The AGM-88 can detect, attack and destroy a radar antenna or transmitter with minimal aircrew input. The proportional navigation, proportional guidance system that homes in on enemy radar emissions has a fixed antenna and seeker head in the missile's nose. A smokeless, solid-propellant, dual-thrust, booster-sustainer rocket motor propels the missile at speeds over Mach number, Mach 2. The HARM was a missile program led by the U.S. Navy, and it was first carried by the A-6 Intruder, A-6E, A-7 Corsair II, A-7, a ...

Anti-radiation Missile
An anti-radiation missile (ARM) is a missile designed to detect and home in on an enemy radio emission source. Typically, these are designed for use against an enemy radar, although jammers and even radios used for communications can also be targeted in this manner. The earliest known anti-radiation weapon is a variant of the Blohm & Voss BV 246 radar guided bomb.Lepage, Jean-Denis G.G. (2009). Aircraft of the Luftwaffe 1935-1945. McFarland. p. 67. . Home-on-jam As jammers proliferated, a number of existing ARMs such as the AGM-88 HARM was modified to also target jammers as the source of radiation. Jammers also led to the addition of a feature to missiles that usually use a different targeting mode (e.g. active radar homing, semi-active radar homing, GPS), allowing them to switch to an anti-radiation targeting mode when radar deteriorates too much. Some examples are: * JDAM and JDAM-ER, air-to-surface GPS bomb * AMRAAM, active radar homing air-to-air missile * R-77, active ...

EA-6B
The Northrop Grumman (formerly Grumman) EA-6B Prowler is a twin-engine, four-seat, mid-wing electronic-warfare aircraft. Operated by both the United States Marine Corps and United States Navy between 1971 and 2019, it was derived from the A-6 Intruder airframe. The aircraft's immediate predecessor, the ''EA-6A'', was an interim conversion of the A-6 airframe to perform electronic warfare missions during the 1960s. In 1966, work on the more advanced EA-6B commenced. It featured an enlarged four-seat cockpit, a fully integrated electronic warfare system, and advanced electronic countermeasures. Furthermore, it was suitable for long-range, all-weather carrier-based operations in addition to land-based uses. Typically, the aircrew of an EA-6B consisted of a single pilot and three Electronic Countermeasures Officers, though it was not uncommon for only two ECMOs to be used on missions. It was capable of firing anti-radiation missiles (ARMs), such as the AGM-88 HARM. Although desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stand-in Attack Weapon
The Stand-in Attack Weapon (SiAW) is a tactical air-to-surface missile under development for the United States Air Force (USAF) by Northrop Grumman. It is primarily designed to attack air-defences and high-value targets such as command-and-control sites, surface-to-surface missile launchers, anti-satellite systems, and GPS jamming systems. History In May 2022, the USAF awarded contracts to L3Harris Technologies, Lockheed Martin and Northrop Grumman to begin the first phase of development for the Stand-in Attack Weapon (SiAW). On 28 September 2023, the USAF awarded a US$705m contract to Northrop Grumman to develop and test the SiAW. The SiAW is intended to attack relocatable targets including theater ballistic missile launchers, cruise and anti-ship missile launchers, GPS jamming platforms and anti-satellite systems. It will have a shorter range than standoff weapons, being fired by an aircraft after penetrating enemy airspace. The SiAW will fit inside the F-35 Lightning II's i ...

Bombing Of Libya (1986)
The United States Air Force, Navy, and Marine Corps carried out air strikes, code-named Operation El Dorado Canyon, against Libya on 15 April 1986 in retaliation for the West Berlin discotheque bombing ten days earlier, which U.S. President Ronald Reagan blamed on Libyan leader Muammar Gaddafi. There were 40 reported Libyan casualties; one U.S. plane was shot down. One of the claimed Libyan deaths was of a baby girl, reported to be Gaddafi's daughter, Hana Gaddafi. However, there are doubts both as to whether she was really killed, or even if she truly existed. Origins Libya represented a high priority for President Ronald Reagan shortly after his 1981 inauguration. Libyan leader Muammar Gaddafi was firmly anti-Israel and had supported Resistance organizations in the Palestinian territories and Syria. There were reports that Libya was attempting to become a nuclear power and Gaddafi's occupation of Chad, which was rich in uranium, was of major concern to the United States. ...

Air-to-surface Missile
An air-to-surface missile (ASM) or air-to-ground missile (AGM) is a missile designed to be launched from military aircraft at targets on land or sea. There are also unpowered guided glide bombs not considered missiles. The two most common propulsion systems for air-to-surface missiles are rocket motors, usually with shorter range, and slower, longer-range jet engines. Some Soviet Union, Soviet-designed air-to-surface missiles are powered by ramjets, giving them both long range and high speed. Missile guidance, Guidance for air-to-surface missiles is typically via laser guidance, infrared homing, infrared guidance, optical guidance or via satellite guidance signals. The type of guidance depends on the type of target. Ships, for example, may be detected via passive radar or active radar homing, which is less effective against multiple, small, fast-moving land targets. There is some cross-over between air-to-surface missiles and surface-to-surface missiles. For example, there was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Thiokol
Thiokol was an American corporation concerned initially with rubber and related chemicals, and later with rocket and missile propulsion systems. Its name is a portmanteau of the Greek words for sulfur () and glue (), an allusion to the company's initial product, Thiokol polymer. The Thiokol Chemical Company was founded in 1929. Its initial business was a range of synthetic rubber and polymer sealants. Thiokol was a major supplier of liquid polymer sealants during World War II. When scientists at the Jet Propulsion Laboratory discovered that Thiokol's polymers made ideal binders for solid rocket fuels, Thiokol moved into the new field, opening laboratories at Elkton, Maryland, and later production facilities at Elkton and at Redstone Arsenal in Huntsville, Alabama. Huntsville produced the XM33 Pollux, TX-18 Falcon, and TX-135 Nike-Zeus systems. It closed in 1996. In the mid-1950s the company bought extensive lands in Utah for its rocket test range. Thiokol was involved in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
