Brazo Largo, Entre Ríos
The Brazo () missile was an American project of the 1970s, intended to produce an anti-radiation missile for air-to-air use. Developed by Hughes Aircraft and based on the AIM-7 Sparrow air-to-air missile, the Brazo underwent a series of successful test firings; however, the program was terminated at the end of its test program. Design and development A joint development project between Hughes Aircraft and the United States Navy, the Brazo missile (named as a pun by one of the project's Navy developers, a Hispanic; "Brazo" is Spanish for "Arm", the acronym for an Anti-Radiation Missile) project was initiated in 1972, as a proof-of-concept demonstration of the utility of an air-to-air, anti-radar missile.Parsch 2003 In 1973, the United States Air Force's Pave Arm project, a program with similar goals, was merged into the Brazo program, with the Air Force assuming responsibility for testing the missile.Friedman 1982, p.179. The first air-to-air anti-radiation missile developed by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

BQM-34 Firebee
The Ryan Firebee is a series of target drones developed by the Ryan Aeronautical Company beginning in 1951. It was one of the first jet-propelled drones, and remains one of the most widely used target drones ever built. Development Ryan Firebee I Q-2/KDA-1 Firebee The Firebee I was the result of a 1948 U.S. Air Force request and contract to Ryan for a jet-powered gunnery target. The first flight of the XQ-2 Firebee prototype took place in early 1951. The drone featured swept flight surfaces and a circular nose inlet. The initial models had distinctive "arrowhead" shaped endplates on the tailplane. The Firebee could be air-launched from a specially modified launch aircraft (Douglas A-26 Invader was first to be used for this purpose), or ground-launched with a single RATO booster. Following successful evaluation the target was ordered into production for the USAF as the Q-2A, powered by a Continental J69-T-19B turbojet engine with of thrust. The Air Force then obtained smal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
F-4D Phantom II
The McDonnell Douglas F-4 Phantom II is an American tandem two-seat, twin-engine, all-weather, long-range supersonic jet interceptor and fighter-bomber that was developed by McDonnell Aircraft for the United States Navy.Swanborough and Bowers 1976, p. 301. It entered service with the Navy in 1961, then was adopted by the United States Marine Corps, and the United States Air Force, and within a few years became a major part of their air arms. A total of 5,195 Phantoms were built from 1958 to 1981, making it the most-produced American supersonic military aircraft in history and a signature combat aircraft of the Cold War."F-4 Phantoms Phabulous 40th" Boeing.

Airborne Early Warning And Control
An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial warfare, aerial engagements by informing and directing friendly fighter aircraft, fighter and attack aircraft. AEW&C units are also used to carry out aerial surveillance airborne ground surveillance, over ground and maritime surveillance, maritime targets, and frequently perform battle management command and control (BMC2). When used at altitude, the radar system on AEW&C aircraft allows the operators to detect, track and prioritize targets and identify friendly aircraft from hostile ones in real-time and from much farther away than ground-based radars. Like ground-based radars, AEW&C systems can be detected and targeted by opposing forces, but due to aircraft mobility and extended sensor range, they are much less vul ...

Naval Electronics Center
The U.S. Navy Electronics Laboratory (NEL) was created in 1945, with consolidation of the naval radio station, radar operators training school, and radio security activity of the Navy Radio and Sound Lab (NRSL) and its wartime partner, the University of California Division of War Research. NEL’s charter was “''to effectuate the solution of any problem in the field of electronics, in connection with the design, procurement, testing, installation and maintenance of electronic equipment for the U.S. Navy.''” Its radio communications and sonar work was augmented with basic research in the propagation of electromagnetic energy in the atmosphere and of sound in the ocean. History In November 1945, the Navy Radio and Sound Lab was renamed as Navy Electronics Laboratory. 80% of the Point Loma Military Reservation evolved into the Naval Electronics Laboratory Center (NELC) at the end of World War II. In turn NELC was merged into the Naval Ocean Systems Center (NOSC) in 1977. This eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passive Radar
Passive radar (also referred to as parasitic radar, passive coherent location, passive surveillance, and passive covert radar) is a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals. It is a specific case of ''bistatic radar'' – passive bistatic radar (PBR) – which is a broad type also including the exploitation of cooperative and non-cooperative radar transmitters. Introduction Conventional radar systems comprise a colocated transmitter and receiver (radio), receiver, which usually share a common antenna (radio), antenna to transmit and receive. A pulsed signal is transmitted and the time taken for the pulse to travel to the object and back allows the range of the object to be determined. In a passive radar system, there is no dedicated transmitter. Instead, the receiver uses third-party transmitters in the environment and m ...

AIM-7E Sparrow
The AIM-7 Sparrow (Air Intercept Missile) is an American medium-range semi-active radar homing air-to-air missile operated by the United States Air Force, United States Navy, United States Marine Corps, and various other air forces and navies. Sparrow and its derivatives were the West's principal beyond visual range (BVR) air-to-air missile from the late 1950s until the 1990s. It remains in service, although it is being phased out in aviation applications in favor of the more advanced AIM-120 AMRAAM. The early Sparrow was intended primarily for use against larger targets, especially bombers, and had numerous operational limitations in other uses. Against smaller targets, the need to receive a strong reflected radar signal made it difficult to achieve lock-on at the missile's effective range. As the launching aircraft's own radar needed to be pointed at the target throughout the engagement, this meant that in fighter-vs-fighter combat the enemy fighter would often approach within ...

Air-to-air Missile
An air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft (including unmanned aircraft such as cruise missiles). AAMs are typically powered by one or more rocket motors, usually solid-fuel rocket, solid fueled but sometimes liquid-fuel rocket, liquid fueled. Ramjet engines, as used on the Meteor (missile), Meteor, are emerging as propulsion that will enable future medium- to long-range missiles to maintain higher average speed across their engagement envelope. Air-to-air missiles are broadly put in two groups. Those designed to engage opposing aircraft at ranges of around 30 km to 40 km maximum are known as short-range or "within visual range" missiles (SRAAMs or WVRAAMs) and are sometimes called "dogfight" missiles because they are designed to optimize their agility rather than range. Most use infrared guidance and are called heat-seeking missiles. In contrast, medium- or long-range missiles (MRAAMs or LRAAMs), which ...
