Man-portable air-defense system
MANPADS were developed in the 1950s to provide military ground forces with protection from jet aircraft. They have received a great deal of attention, partly because armed groups have used them against commercial airliners. These missiles, affordable and widely available through a variety of sources, have been used successfully over the past three decades both in military conflicts, as well as by terrorist organizations.
Twenty-five countries, including the United Kingdom, the United States, Sweden, Russia, and Turkey, produce man-portable air defense systems. Possession, export, and trafficking of such weapons is officially tightly controlled, due to the threat they pose to civil aviation, although such efforts have not always been successful.
The missiles are about 1.5 to 1.8 m (5 to 6 ft) in length and weigh about 17 to 18 kg (37 to 40 lb), depending on the model. MANPADS generally have a target detection range of about 10 km (6 mi) and an engagement range of about 6 km (4 mi), so aircraft flying at 6,100 metres (20,000 ft) or higher are relatively safe.
The acronym MANPADS is commonly altered into a singular form of "MANPAD" to describe a single weapon of the type. The terminal "S" of the original acronym does not necessarily indicate a plural, indicating instead the singular "system" or the plural "systems".
Infrared homing missiles are designed to home-in on a heat source on an aircraft, typically the engine exhaust plume, and detonate a warhead in or near the heat source to disable the aircraft. These missiles use passive guidance, meaning that they do not emit signals to detect a heat source, which makes them difficult to detect by targeted aircraft employing countermeasure systems.
The first missiles deployed in the 1960s were infrared missiles. First generation MANPADS, such as the US Redeye, early versions of the Soviet 9K32 Strela-2, and the Chinese HN-5 (copy of Soviet Strela-2), are considered "tail-chase weapons" as their uncooled spin-scan seekers can only discern the superheated interior of the target's jet engine from background noise. This means they are only capable of accurately tracking the aircraft from the rear when the engines are fully exposed to the missile's seeker and provide a sufficient thermal signature for engagement. First generation IR missiles are also highly susceptible to interfering thermal signatures from background sources, including the sun, which many experts feel makes them somewhat unreliable, and they are prone to erratic behaviour in the terminal phase of engagement. While less effective than more modern weapons, they remain common in irregular forces as they are not limited by the short shelf-life of gas coolant cartridges used by later systems.
Second generation infrared missiles, such as early versions of the U.S. Stinger, the Soviet Strela-3, and the Chinese FN-6, use gas-cooled seeker heads and a conical scanning technique, which enables the seeker to filter out most interfering background IR sources as well as permitting head-on and side engagement profiles. Later versions of the Redeye MANPADS are regarded as straddling the first and second generations as they are gas-cooled but still use a spin-scan seeker.
Third generation infrared MANPADS, such as the French Mistral, the Soviet 9K38 Igla, and the US Stinger B, use rosette scanning detectors to produce a quasi-image of the target. Their seeker compares input from multiple detections bands, either two widely separated IR bands or IR and UV, giving them much greater ability to discern and reject countermeasures deployed by the target aircraft.
Fourth generation missiles, such as the cancelled American FIM-92 Stinger Block 2, Russian Verba, Chinese QW-4, and Japanese Type 91 surface-to-air missile use imaging infrared focal plane array guidance systems and other advanced sensor systems, which permit engagement at greater ranges.
Command guidance (CLOS) missiles do not home in on a particular aspect (heat source or radio or radar transmissions) of the targeted aircraft. Instead, the missile operator or gunner visually acquires the target using a magnified optical sight and then uses radio controls to "fly" the missile into the aircraft. One of the benefits of such a missile is that it is virtually immune to flares and other basic countermeasure systems that are designed primarily to defeat IR missiles. The major drawback of CLOS missiles is that they require highly trained and skilled operators. Numerous reports from the Soviet–Afghan War in the 1980s cite Afghan mujahedin as being disappointed with the British-supplied Blowpipe CLOS missile because it was too difficult to learn to use and highly inaccurate, particularly when employed against fast moving jet aircraft. Given these considerations, many experts believe that CLOS missiles are not as ideally suited for untrained personnel use as are IR missiles, which sometimes are referred to as "fire and forget" missiles.
Later versions of CLOS missiles, such as the British Javelin, use a solid state television camera in lieu of the optical tracker to make the gunner's task easier. The Javelin's manufacturer, Thales Air Defence, claims that their missile is virtually impervious to countermeasures.
Laser guided MANPADS use beam-riding guidance where a sensor in the missile's tail detects the emissions from a laser on the launcher and attempts to steer the missile to fly at the exact middle of the beam, or between two beams. Missiles such as Sweden's RBS-70 and Britain's Starstreak can engage aircraft from all angles and only require the operator to continuously track the target using a joystick to keep the laser aim point on the target: the latest version of RBS 70 features a tracking engagement mode where fine aim adjustments of the laser emitter are handled by the launcher itself, with the user only having to make coarse aim corrections. Because there are no radio data links from the ground to the missile, the missile cannot be effectively jammed after it is launched. Even though beam-riding missiles require relatively extensive training and skill to operate, many experts consider these missiles particularly menacing due to the missiles' resistance to most conventional countermeasures in use today.

Against civilian aircraft
- The 1978 Air Rhodesia Viscount shootdown is the first example of a civilian airliner shot down by a man-portable surface-to-air missile. The pilot of the aircraft managed to make a controlled crash landing.
- Air Rhodesia Flight 827 was also shot down in February 1979 by the Zimbabwe People's Revolutionary Army armed with a Strela 2 missile. All 59 passengers and crew were killed.
- 1993 Transair Georgian Airline shootdowns involved two separate aircraft shot down a day apart in Sukhumi, Abkhazia, Georgia, killing 108 people.
- On 6 April 1994, a surface-to-air missile struck one of the wings of the Dassault Falcon 50 carrying three French crew and nine passengers, including Rwandan president Juvénal Habyarimana and Burundian president Cyprien Ntaryamira, as it prepared to land in Kigali, Rwanda, before a second missile hit its tail. The plane erupted into flames in mid-air before crashing into the garden of the presidential palace, exploding on impact. This incident was the ignition spark of the Rwandan genocide.
- 1998 Lionair Flight LN 602 shootdown: On 7 October 1998, the Tamil Tigers shot down an aircraft off the coast of Sri Lanka.
- 2002 Mombasa airliner attack: On 28 November 2002, two shoulder-launched Strela 2 (SA-7) surface-to-air missiles were fired at a chartered Boeing 757 airliner as it took off from Moi International Airport. The missiles missed the aircraft which continued safely to Tel Aviv, carrying 271 vacationers from Mombasa back to Israel. In the photos, the missile systems were painted in light blue, the color used in the Soviet military for training material (a training SA-7 round would not have the guidance system).
- 2003 Baghdad DHL shootdown incident: On 22 November 2003, an Airbus A300B4-203F cargo plane, operating on behalf of DHL was hit by an SA-14 missile, which resulted in the loss of its hydraulic systems. The crew later landed the crippled aircraft safely by using only differential engine thrust by adjusting the individual throttle controls of each engine.

Witnesses claim that a surface-to-air missile was fired immediately prior to the accident. However, Somali officials deny that the aircraft was shot down.
Man-portable air defense systems are a popular black market item for insurgent forces. Their proliferation became the subject of the Wassenaar Arrangement's (WA)22 Elements for Export Controls of MANPADS, the G8 Action Plan of 2 June 2003, the October 2003 Asia-Pacific Economic Cooperation (APEC) Summit, Bangkok Declaration on Partnership for the Future and in July 2003 the Organization for Security and Co-operation in Europe (OSCE), Forum for Security Co-operation, Decision No. 7/03: Man-portable Air Defense Systems.
Understanding the problem in 2003, Colin Powell remarked that there was "no threat more serious to aviation" than the missiles, which can be used to shoot down helicopters and commercial airliners, and are sold illegally for as little as a few hundred dollars. The U.S. has led a global effort to dismantle these weapons, with over 30,000 voluntarily destroyed since 2003, but probably thousands are still in the hands of insurgents, especially in Iraq, where they were looted from the military arsenals of the former dictator Saddam Hussein, and in Afghanistan as well. In August 2010, a report by the Federation of American Scientists (FAS) confirmed that "only a handful" of illicit MANPADS were recovered from national resistance caches in Iraq in 2009, according to media reports and interviews with military sources.
With the growing number of MANPADS attacks on civilian airliners, a number of different countermeasure systems have been developed specifically to protect aircraft against the missiles.
- AN/ALQ-144, AN/ALQ-147 and AN/ALQ-157 are U.S.-produced systems, developed by Sanders Associates in the 1970s.
- AN/ALQ-212 ATIRCM, AN/AAQ-24 Nemesis are NATO systems developed by BAE Systems and Northrop Grumman respectively.
