![]() The command line receiver is used when it is necessary to correct the missile's trajectory in the midrange. This computer can choose a guidance trajectory in which the missile will reach the target at the angle that has the greatest effect on the engagement of a warhead. For example, on the basis of the measured range and angle of the target sighting line, as well as the speed of their change, the microcomputer calculates the target acceleration, and with the known own acceleration obtained with the help of inertial platform, it calculates its possible maneuvers. Introduction of such microcomputer allowed to increase significantly the number of parameters used for calculation of the most optimal guidance trajectory depending on the mutual location of the missile and the target at the point of meeting, their speeds and flight directions. It performs all functions of control, command communication, signal processing of radar equipment and fuses, as well as built-in control when checking the performance of major components and units of the equipment. High-performance microcomputer operating with 30 MHz clock frequency is common for command-inertial and radar systems. Weight of the platform, which uses miniature high-speed gyroscopes, is less than 1.4 kg. The equipment of the command-inertial system includes a kindless inertial platform and a command line receiver located in the nozzle block of the UR tail part. The range of target ARGS with EPR a = 3m2 is 16.18km. ARGS uses a generator of a sounding signal using a running wave lamp, which has an output power of 500W. The active radar operates in the same frequency band X (3cm) as the radar. The main part of the autonomous guidance equipment is concentrated in the head compartment, which is carried out with the help of the combined system - command-inertial on the initial and middle parts of the flight path and active radar on the final one. ![]() The SD casing is made of grey painted steel that can withstand significant kinetic heat. It has a cross-shaped wing of a small area, which provides enough maneuverability at low flight speeds, and cross-shaped rudders in the tail unit. The AIM-120 missile follows the normal aerodynamic scheme and consists of three compartments: the main compartment, the combat unit (BC) and the tail compartment (see the scheme). The first combat application took place in December 1992, when an American F-16 fighter aircraft shot down MiG-25 of the Iraqi Air Force over the territory of southern Iraq. This was made possible thanks to modern achievements in aircraft control theory, radio electronics and computer technology, propulsion systems and combat equipment.Ī small number of F-18 fighters armed with AIM-120 missiles were relocated to the Persian Gulf area in 1991 as part of Operation Desert Storm, but they were not used in combat operations. AMRAAM missiles were combined with F-22, Eurofighter Typhoon and Harrier-II aircraft.Ĭompared to the Sparrow AIM-120, the launch weight and dimensions of the missile have been significantly reduced, and the effectiveness of the fight against both high-altitude, energetically manoeuvring and low-altitude targets has been improved under conditions of intensive electronic warfare. The new missiles were placed on the same LAU-17A and LAU-92 launchers. The rearmament of the fighter fleets of these countries (F-4F, F-14D, F-15, F-16, F/A-18, Tornado, Harrier, JAS-39 Grippen, JA-37 Viggen) with the above mentioned missiles is made instead of AIM-7F, A1M-7M Sparrow. ![]() In April 1998, the company "Raytheon Company System" received an order for the production of 813 AIM-120 missiles worth $ 243 million.ĪMRAAM missiles of AIM-120A, A1M-120B, AIM-120B+, AIM-120C and AIM-120C-5 modifications are now the main air-to-air weapons of the US, NATO and other fighters (about 18 in total). The missile was adopted for service with the U.S. The Air-to-Air Missile (AIM-120) is an air-to-air guided all-weather missile originally designated AMRAAM (Advanced Medium-Range Air-to-Air Missile) developed by Hughes Aircraft Co. ![]()
