SA-18 Grouse
Encyclopedia : S : SA : SA1 : SA-18 Grouse
The 9K38 "Igla" (Russian 9К38 "Игла́" – needle, NATO reporting name SA-18 Grouse) is a Russian/Soviet man-portable infrared homing surface-to-air missile (SAM) system. Its most advanced version, the Igla, has an all-aspect engagement capability.
A variant is the 9K310 "Igla-1", which has the NATO reporting name SA-16 Gimlet.
The Igla-M (NATO SA-N-10 Grouse) is a naval variant.
History
Development of the Igla short-range man-portable air defence missile (MANPADS) began in the Kolomna OKB in 1971. Contrary to what is commonly reported, the Igla is not an improved version of the earlier Strela family (Strela-2/SA-7 and Strela-3/SA-14), but an all new project. The main goals were to create a missile with better resistance to countermeasures and wider engagement envelope than the earlier Strela series MANPADS systems.
Technical difficulties in the development quickly made it obvious that the development would take far longer than anticipated, however, and in 1978 the program split in two: while the development of the full-capability Igla would continue, a simplified version (Igla-1) with a simpler IR seeker based on that of the earlier Strela-3/SA-14 would be developed to enter service earlier than the full-capability version could be finished.
Igla-1
The 9K310 Igla-1 system (NATO reporting name SA-16 Gimlet) and its 9M313 missile were accepted into service in the Soviet army on 11 March, 1981. Main differences from the Strela-3 include:
- Optional IFF (Identification-Friend-or-Foe) system to prevent firing on friendly aircraft.
- Automatic lead and super elevation to simplify shooting and reduce minimum firing range.
- Slightly larger rocket, reduced drag and better guidance system extend maximum range and improve performance against fast and maneuverable targets.
- Improved lethality on target achieved by a combination of delayed impact fusing, terminal maneuver to hit the fuselage rather than jet nozzle, and an additional charge to set off the remaining rocket fuel (if any) on impact.
- Improved resistance to countermeasures (both decoy flares and ALQ-144 series jamming emitters).
- Slightly improved seeker sensitivity.
According to Kolomna OKB, the Igla-1 has a Pk (probability of kill) of 0.30 to 0.48 against unprotected targets which is reduced to 0.24 in the presence of decoy flares and jamming. In another report the manufacturer claimed a Pk of 0.59 against an approaching and 0.44 against receding F-4 fighter not employing infra-red countermeasures or evasive manoeuvers.
Igla
The full-capability 9K38 Igla (NATO reporting name SA-18 Grouse) with 9M39 missile was finally accepted to service in the Soviet Army in 1983. The main improvements over the Igla-1 include:
- much improved resistance against flares and jamming.
- more sensitive seeker, expanding forward-hemisphere engagement capability to include straight-approaching fighters (all-aspect capability) under favourable circumstances.
- slightly longer range.
- a higher-impulse, shorter-burning rocket with higher peak velocity (but approximately same time of flight to maximum range), and a propellant that performs as high explosive when detonated by the warhead's secondary charge on impact.
Other variants
Several variants of the Igla were developed for specific applications:
- Igla-1E - Export version?.
- Igla-1M - Naval version (NATO reporting name SA-N-10).
- Igla-1D - A version for paratroopers and special forces with separate launch tube and missile.
- Igla-1V - Air-launched version, mainly for combat helicopters.
- Igla-1N - A version with heavier warhead at the cost of a slight reduction in range and speed.
- Igla-1A - Export version?.
- The newest variant is Igla-1S, which is a substantially improved variant with longer range, more sensitive seeker, improved resistance to latest countermeasures, and a heavier warhead.

Use in alleged plot against
On August 12, 2003, as a result of a sting operation arranged as a result of cooperation between the American, British and Russian intelligence agencies, Hemant Lakhani, a British national, was intercepted attempting to bring what he had thought was an older-generation Igla into the USA. He is said to have intended the missile to be used in an attack on Air Force One, the American presidential plane, or on a commercial US airliner, and is understood to have planned to buy 50 more of these weapons.
Allegedly, after the Federalnaya Sluzhba Bezopasnosti detected the dealer in Russia, he was approached by US undercover agents posing as terrorists wanting to down a commercial plane. He was then provided with a non-working Igla by undercover Russian agents, and arrested in Newark, New Jersey, when making the delivery to the undercover US agent. An Indian citizen residing in Malaysia, Moinuddeen Ahmed Hameed and an American Yehuda Abraham who allegedly provided money to buy the missile were also arrested.
Igla and Igla-1 SAMs have been exported from Russia to over 30 countries, including Bosnia and Herzegovina, Bulgaria, Croatia, Germany, Malaysia, Finland, India, Iraq, Poland, Singapore, Serbia, Montenegro, Slovenia, South Korea and Syria. Several guerrilla and terrorist organizations are also known to have Iglas. In 2003 the unit cost was approximately USD 60,000 - 80,000.
