Air-to-air missile
Encyclopedia
An air-to-air missile (AAM) is a missile
fired from an aircraft
for the purpose of destroying another aircraft. AAMs are typically powered by one or more rocket motors, usually solid fuelled but sometimes liquid fuelled. Ramjet
engines, as used on the MBDA Meteor
(currently in development), are emerging as propulsion that will enable future medium-range missiles to maintain higher average speed across their engagement envelope.
Air-to-air missiles are broadly put in two groups. The first consists of missiles designed to engage opposing aircraft at ranges of less than approximately 20 miles (32 km), these are known as short-range or “within visual range” missiles (SRAAMs or WVRAAMs) and are sometimes called “dogfight
” missiles because they emphasize agility rather than range. These usually use infrared guidance, and are hence also called heat-seeking missiles. The second group consists of medium- or long-range missiles (MRAAMs or LRAAMs), which both fall under the category of beyond visual range
missiles (BVRAAMs). BVR missiles tend to rely upon some sort of radar guidance, of which there are many forms, modern ones also using inertial guidance and/or "mid-course updates".
s used during the First World War. Le Prieur rocket
s were sometimes attached to the struts of biplanes and fired electrically, usually against observation balloons, by such early pilots as Albert Ball
and A. M. Walters. Facing the Allied air superiority in World War II
, Germany
invested considerable effort into missile research, using the R4M
unguided rocket first and later the first guided rockets like the Ruhrstahl X-4
.
Post-war research led the Royal Air Force
to introduce Fairey Fireflash
into service in 1955 but their results were unsuccessful. The US Navy and US Air Force began equipping guided missiles in 1956, deploying the USAF's AIM-4 Falcon
and the USN's AIM-7 Sparrow
and AIM-9 Sidewinder
. The Soviet Air Force
introduced its Kaliningrad K-5
into service in 1957. As missile systems have continued to advance, modern air warfare consists almost entirely of missile firing. The faith in Beyond Visual Range
combat became so pervasive in the US that early F-4
variants were armed only with missiles in the 1960s. High casualty rates during the Vietnam War
caused the US to reintroduce autocannon
s and traditional dogfighting tactics but the missile remains the primary weapon in air combat. In the Falklands War
British Harriers
were able to defeat faster Argentinian opponents using AIM-9L missiles provided by the United States as the conflict began http://www.thehistorychannel.co.uk/site/microsites/Falklands/index_microsite.php?microsite=Falklands&target=The_Harrier§ion=626. The latest heat-seeking designs can lock-on
to a target from various angles, not just from behind, where the heat signature from the engines is strongest. Other types rely on radar guidance (either on-board or "painted" by the launching aircraft).
warhead, or continuous rod warhead (or a combination of any of those three warhead types) is typically used in the attempt to disable or destroy the target aircraft. Warheads are typically detonated by a proximity fuze
or by an impact fuze if it scores a direct hit. Less commonly, nuclear warheads have been mounted on a small number of air-to-air missile types (such as the AIM-26 Falcon
) although these are not known to have ever been used in combat.
Guided missiles operate by detecting their target (usually by either radar
or infrared
methods, although rarely others such as laser guidance
or optical tracking), and then “homing” in on the target on a collision course.
Note that although the missile may use radar or infra-red guidance to home on the target, this does not necessarily mean that the same means is used by the launching aircraft to detect and track the target before launch. Infra-red guided missiles can be “slaved” to an attack radar in order to find the target and radar-guided missiles can be launched at targets detected visually or via an infra-red search and track
(IRST) system, although they may require the attack radar to illuminate the target during part or all of the missile interception itself.
Radar guided missiles can be countered by rapid maneuvering (which may result in them “breaking lock”, or may cause them to overshoot), deploying chaff
or using electronic counter-measures.
, inertial guidance, or a mid-course update from either the launching aircraft or other system that can communicate with the missile to get the missile close to the target. At a predetermined point (frequently based on time since launch or arrival near the predicted target location) the missile's radar system is activated (the missile is said to "go active") and the missile then homes in on the target.
If the range from the attacking aircraft to the target is within the range of the missile's radar system the missile can "go active" immediately upon launch.
The great advantage of an Active Radar Homing system is that it enables a "Fire-and-forget
" mode of attack, where the attacking aircraft is free to pursue other targets or escape the area after launching the missile.
However, this means that the launch aircraft has to maintain a “lock” on the target (keep illuminating the target aircraft with its own radar) until the missile makes the interception. This limits the attacking aircraft's ability to maneuver, which may be necessary should threats to the attacking aircraft appear.
An advantage of SARH guided missiles is that they are homing on the reflected radar signal so accuracy actually increases as the missile gets closer because the reflection comes from a "point source": the target. Against this, if there are multiple targets, each will be reflecting the same radar signal and the missile may become confused as to which target is its intended victim. The missile may well be unable to pick a specific target and fly through a formation without passing within lethal range of any specific aircraft. Newer missiles have logic circuits in their guidance systems to help prevent this problem.
At the same time, jamming the missile lock-on
is easier because the launching aircraft is further from the target than the missile, so the radar signal has to travel further and is greatly attenuated over the distance. This means that the missile may be jammed or "spoofed" by countermeasures whose signals grow stronger as the missile gets closer. One counter to this is a "home on jam" capability in the missile that allows it to home in on the jamming signal.
While simple in concept, the difficulty of simultaneously keeping the beam solidly on the target (which couldn't be relied upon to cooperate by flying straight and level), continuing to fly one's own aircraft, all the while keeping an eye out for enemy countermeasures, can be readily appreciated.
An added complication was that the beam will spread out into a cone shape as the distance from the attacking aircraft increases. This will result in less accuracy for the missile because the beam may actually be larger than the target aircraft when the missile arrives. The missile could be securely within the beam but still not be close enough to destroy the target.
More modern infra-red guided missiles can detect the heat of an aircraft's skin, warmed by the friction of airflow, in addition to the fainter heat signature of the engine when the aircraft is seen from the side or head-on. This, combined with greater maneuverability, gives them an “all-aspect
” capability, and an attacking aircraft no longer had to be behind its target to fire. Although launching from behind the target increases the probability of a hit, the launching aircraft usually has to be closer to the target in such a tail-chase engagement
.
An aircraft can defend against infra-red missiles by dropping flares
that are hotter than the aircraft, so the missile homes in on the brighter, hotter target. In turn, IR missiles may employ filters to enable it to ignore targets whose temperature is not within a specified range.
Towed decoys which closely mimic engine heat and infra-red jammers can also be used. Some large aircraft and many combat helicopters make use of so called "hot brick" infra-red jammers, typically mounted near the engines. Current research is developing laser devices which can spoof or destroy the guidance systems of infra-red guided missiles. See Infrared countermeasure.
However, the latest missiles such as the ASRAAM use an “imaging” infra-red seeker which “sees” the target (much like a digital video camera), and can distinguish between an aircraft and a point heat source such as a flare. They also feature a very wide detection angle, so the attacking aircraft does not have to be pointing straight at the target for the missile to lock on. The pilot can use a helmet mounted sight (HMS) and target another aircraft by looking at it, and then firing. This is called “off-boresight” launch. For example, the Russian Su-27 is equipped with an infra-red search and track (IRST) system with laser rangefinder for its HMS-aimed missiles.
In order to maneuver sufficiently from a poor launch angle at short ranges to hit its target, missiles are now employing gas-dynamic
flight control methods such as vectored thrust, which allow the missile to start turning “off the rail”, before its motor has accelerated it up to high enough speeds for its small aerodynamic surfaces to be useful.
However clouds can get in the way of electro-optical sensors.
Due to their dependence on target aircraft radar emissions, when used against fighter aircraft passive anti-radiation missiles are primarily limited to forward-aspect intercept geometry. For examples, see Vympel R-27, Brazo
, and AIM-97 Seekbat
.
Another aspect of passive anti-radiation homing is the "home on jam" mode which, when installed, allows a radar-guided missile to home in on the jammer of the target aircraft if the primary seeker is jammed by the electronic countermeasures
of the target aircraft
At the front is the seeker, either a radar system, radar homer, or infra-red detector. Behind that lies the avionics which control the missile. Typically after that, in the centre of the missile, is the warhead, usually several kilograms of high explosive surrounded by metal that fragments on detonation (or in some cases, pre-fragmented metal).
The rear part of the missile contains the propulsion system, usually a rocket of some type. Dual-thrust
solid-fuel rockets are common, but some longer-range missiles use liquid-fuel motors that can “throttle” to extend their range and preserve fuel for energy-intensive final maneuvering. Some solid-fuelled missiles mimic this technique with a second rocket motor which burns during the terminal homing phase. There are missiles in development, such as the MBDA Meteor, that “breathe” air (using a ramjet
, similar to a jet engine) in order to extend their range.
Modern missiles use “low-smoke” motors — early missiles produced thick smoke trails, which were easily seen by the crew of the target aircraft alerting them to the attack and helping them determine how to evade it.
Poorly-trained pilots are known to fire their missiles at maximum-range engagement with poor results. In the 1998–2000 Eritrean-Ethiopian War
, fighters from both sides shot over a dozen medium-range R-27 (AA-10 Alamo) missiles at distance with little effect. But when better-trained Ethiopian Su-27
pilots gave chase and attacked with short-range R-73 (AA-11 Archer)
missiles, the results were often deadly to the Eritrean aircraft. http://www.acig.org/artman/publish/article_189.shtml

).
(AA-2 Atoll) had infrared seekers with a narrow (30 degree) field of view and required the attacker to position himself behind the target (rear aspect engagement
). This meant that the target aircraft only had to perform a slight turn to move outside the missile seeker's field of view and cause the missile to lose track of the target ("break lock").
(AA-11 Archer) entered service in 1985 and marked a new generation of dogfight missile. These missiles employed more advanced seeker technologies such as focal plane arrays that improved resistance to infrared countermeasures (IRCM) such as flares and increased off-bore sight capability to in excess of 60 degrees, i.e. a 120 degree field of view.
To take advantage of the increased field-of-view that now exceeded the capabilities of most aircraft radars also meant that helmet mounted sights gained popularity.
Many newer missiles include what is known as “look-down-shoot-down” capability, as they could be fired onto low flying planes that would formerly be lost in ground clutter.
These missiles are also much more agile, some by employing thrust vectoring
(typically gimballed thrust
).

" mode of attack, where the attacking aircraft is free to pursue other targets or escape the area after launching the missile.
Semi-active radar homing
Semi-active radar homing (SARH) guided missiles are simpler and more common. They function by detecting radar energy reflected from the target. The radar energy is emitted from the launching aircraft's own radar system.However, this means that the launch aircraft has to maintain a “lock” on the target (keep illuminating the target aircraft with its own radar) until the missile makes the interception.

This means that the missile may be jammed or "spoofed" by countermeasures whose signals grow stronger as the missile gets closer. One counter to this is a "home on jam" capability in the missile that allows it to home in on the jamming signal.
Beam riding
An early form of radar guidance was “beam-riding” (BR). In this method the attacking aircraft directed a narrow beam of radar energy at the target. The air-to-air missile was launched into the beam where sensors on the aft of the missile controlled the missile, keeping it within the beam. So long as the beam was kept on the target aircraft, the missile would ride the beam until making the interception.While simple in concept, the difficulty of simultaneously keeping the beam solidly on the target (which couldn't be relied upon to cooperate by flying straight and level), continuing to fly one's own aircraft, all the while keeping an eye out for enemy countermeasures, can be readily appreciated.
An added complication was that the beam will spread out into a cone shape as the distance from the attacking aircraft increases. This will result in less accuracy for the missile because the beam may actually be larger than the target aircraft when the missile arrives. The missile could be securely within the beam but still not be close enough to destroy the target.
Infrared guidance
Infrared guided (IR) missiles home on the heat produced by an aircraft. Early infra-red detectors had poor sensitivity, so could only track the hot exhaust pipes of an aircraft. This meant an attacking aircraft had to maneuver to a position behind its target before it could fire an infra-red guided missile. This also limited the range of the missile as the infra-red signature soon become too small to detect with increasing distance and after launch the missile was playing “catch-up” with its target. Early infrared seekers were unusable in clouds or rain (which is still a limitation to some degree) and could be distracted by the sun, a reflection of the sun off of a cloud or ground object, or any other "hot" object within its view.More modern infra-red guided missiles can detect the heat of an aircraft's skin, warmed by the friction of airflow, in addition to the fainter heat signature of the engine when the aircraft is seen from the side or head-on. This, combined with greater maneuverability, gives them an “all-aspect

Electro-optical
A recent advancement in missile guidance is electro-optical imaging. The Israeli Python-5 has an electro-optical seeker that scans designated area for targets via optical imaging. Once a target is acquired, the missile will lock-on to it for the kill. Electro-optical seekers can be programmed to target vital area of an aircraft, such as the cockpit. Since it does not depend on the target aircraft's heat signature, it can be used against low-heat targets such as UAVs and cruise missiles.However clouds can get in the way of electro-optical sensors.
Passive Anti-radiation
Evolving missile guidance designs are converting the anti-radiation missile (ARM) design, pioneered during Vietnam and used to home in against emitting surface-to-air missile (SAM) sites, to an air intercept weapon. Current air-to-air passive anti-radiation missile development is thought to be a countermeasure to airborne early warning and control (AEW&C - also known as AEW or AWACS) aircraft which typically mount powerful search radars.Due to their dependence on target aircraft radar emissions, when used against fighter aircraft passive anti-radiation missiles are primarily limited to forward-aspect intercept geometry. For examples, see Vympel R-27, Brazo
Brazo
The Brazo missile was an American project, 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; hoever, the program was terminated at the end of its...

The AIM-97 Seekbat is a missile developed by the United States of America.-Overview:In the early to mid 1970s the United States was highly concerned by the perceived capabilities of the MiG-25 Foxbat, an aircraft which was known to be capable of speeds in excess of Mach 3 and which carried long...
.
Another aspect of passive anti-radiation homing is the "home on jam" mode which, when installed, allows a radar-guided missile to home in on the jammer of the target aircraft if the primary seeker is jammed by the electronic countermeasures

of the target aircraft
Design
Air-to-air missiles are typically long, thin cylinders in order to reduce their cross section and thus minimize drag at the high speeds at which they travel.At the front is the seeker, either a radar system, radar homer, or infra-red detector. Behind that lies the avionics which control the missile. Typically after that, in the centre of the missile, is the warhead, usually several kilograms of high explosive surrounded by metal that fragments on detonation (or in some cases, pre-fragmented metal).
The rear part of the missile contains the propulsion system, usually a rocket of some type. Dual-thrust
Dual-thrust
In a dual-thrust solid fuel rocket motor, the propellant mass is composed of two different types or densities of fuel. In the case of a tandem dual-thrust motor, the fuel closest to the rocket nozzle burns fast and the fuel further into the motor's body burns slower...
solid-fuel rockets are common, but some longer-range missiles use liquid-fuel motors that can “throttle” to extend their range and preserve fuel for energy-intensive final maneuvering. Some solid-fuelled missiles mimic this technique with a second rocket motor which burns during the terminal homing phase. There are missiles in development, such as the MBDA Meteor, that “breathe” air (using a ramjet
Ramjet

, similar to a jet engine) in order to extend their range.
Modern missiles use “low-smoke” motors — early missiles produced thick smoke trails, which were easily seen by the crew of the target aircraft alerting them to the attack and helping them determine how to evade it.
Missile range
Missiles are often cited with their maximum engagement range, which is very misleading. A missile's effective range is dependent on factors such as altitude, speed, position, and direction of target aircraft. For example the Vympel R-77 has stated range of 100 km. That is only true for a head-on, non-evading target at high altitude. At low altitude, the effective range is reduced by as much as 75%–80% to 20–25 km. If the target is taking evasive action, or in stern-chase position, the effective range is further reduced. See Air-to-Air missile non-comparison table for more information. The effective range of an air-to-air missile is known as the “no-escape zone”, noting the range at which the target can not evade the missile once launched.Poorly-trained pilots are known to fire their missiles at maximum-range engagement with poor results. In the 1998–2000 Eritrean-Ethiopian War

Performance
A number of terms frequently crop up in discussions of air to air missile performance.Launch success zone
- The Launch Success Zone is the range within which there is a high (defined) kill probability against a target that remains unaware of its engagement until the final moment. When alerted visually or by a warning system the target attempts a last ditch manoeuvre sequence.
F-Pole
- A closely related term is the A-Pole. This is the slant range between the launch aircraft and target, at the time of interception. The greater the F-Pole, the greater the confidence that the launch aircraft will achieve air superiority with that missile.
No-Escape Zone
- The No-Escape Zone is the zone within which there is a high (defined) kill probability against a target even if it has been alerted. This zone is defined as a conical shape with the tip at the missile launch. The cone's length and width are determined by the missile and seeker performance. A missile's speed, range and seeker sensitivity will mostly determine the length of this imaginary cone, while its agility (turn rate) and seeker complexity (speed of detection and ability to detect off axis targets) will determine the width of the cone.
Dogfight
Short-range air-to-air missiles used in “dogfighting” are usually classified into five “generations” according to the historical technological advances. Most of these advances were in infrared seeker technology (later combined with digital signal processingDigital signal processing

). This meant that the target aircraft only had to perform a slight turn to move outside the missile seeker's field of view and cause the missile to lose track of the target ("break lock").
Second generation
Second generation missiles utilized more effective seekers that improved the field of view to 45 degrees.Third generation
This generation introduced “all aspect” missiles, because more sensitive seekers allowed the attacker to fire at a target which was side-on to itself, i.e. from all aspects not just the rear. This meant that while the field-of-view was still restricted to a fairly narrow cone, the attack at least did not have to be behind the target.Fourth generation
The Vympel R-73Vympel R-73
The Vympel R-73 developed by Vympel machine-building design bureau, is the most modern Russian short-range air-to-air missile.-Development:...
(AA-11 Archer) entered service in 1985 and marked a new generation of dogfight missile. These missiles employed more advanced seeker technologies such as focal plane arrays that improved resistance to infrared countermeasures (IRCM) such as flares and increased off-bore sight capability to in excess of 60 degrees, i.e. a 120 degree field of view.
To take advantage of the increased field-of-view that now exceeded the capabilities of most aircraft radars also meant that helmet mounted sights gained popularity.
Many newer missiles include what is known as “look-down-shoot-down” capability, as they could be fired onto low flying planes that would formerly be lost in ground clutter.
These missiles are also much more agile, some by employing thrust vectoring

Fifth generation
