A soldier belonging to Tactical Group Druzhkivka poses with a 9K310 Igla-1 (NATO reporting name SA-16 Gimlet) MANPADS (Man Portable Air Defense System) surface-to-air (SAM) missile launcher. The word “Igla” in Russian means “needle”. Tactical Group Druzhkivka is a Territorial Defense Force unit that operates in and around Druzhkivka, Donetsk Oblast where MANPADS such as the Igla-1 are useful against UAVs and drones.
The Igla-1, which first entered service in 1981, is actually a simplified version of the 9K38 Igla (NATO reporting name SA-18 Grouse) which appeared in service in 1983. The reason for this is that development of the 9K38 was taking longer than expected and so it was decided to push a less complex system into the field to more quickly replace the aging 9K32 Strela-2 (SA-7 Grail) and 9K34 Strela-3 (SA-14 Gremlin) MANPADS.
That this is a 9K310 Igla-1 is denoted by the 9M313 fire-and-forget missile protruding from the 9P322 fiber-glass launch tube with its distinctive aerospike mounted on a tripod attached to the nose. The later 9K38 replaced this with a longer aerospike attached directly to the missile's seeker head. The aerospike is used to reduce drag during flight.
The warhead has a weight of 2.6 pounds of which .9 of a pound accounts for the HE-FRAG (High-Explosive Fragmentation) payload. The missile has two fuzes, one that will detonate the warhead on a direct impact while the second will set off the warhead from a grazing hit on the target. The missile will also attempt to strike the fuselage of the target and to add to the lethality, there is a second charge that will set off any remaining solid fuel for the motor. The seeker head contains two detectors. The first is a cooled mid-wave infrared (MWIR) indium antimonide (InSb) detector for target detection and the second is a uncooled short wavelength infrared (SWIR) lead sulfide (PbS) detector which is used to identify decoy infrared flares. Onboard logic circuits evaluate what the detectors are registering and determine if it is the intended target or flares being deployed to confuse the missile. The missile is also resistant to the U.S. built AN/ALQ-144 series of infrared countermeasure devices.
The solid fuel rocket motor can push the 9M313 missile to a maximum speed of Mach 1.9 while the missile has a operational range of 3.1 miles with a flight ceiling of 11,000 feet. The missile rolls as it flies, imparting stability and the single set of control surfaces is operated by electrically powered pistons, the energy received from a gas turbine within the missile that is fed by a gas generator. This same gas generator can shunt exhaust over the control surfaces if needed when the airspeed is too low for effective steering. The missile's reaction time is between 5 to 10 seconds and it is capable of engaging an oncoming target with an approach speed of 1,017 feet per second or a retreating target with an egress speed of 853 feet per second.
The bulbous object the operator's left hand is holding contains a thermal battery but more importantly, it contains liquid nitrogen coolant that keeps the MWIR InSb detector in the seeker head at optimal temperature prior to launch. The Igla-1 can be fitted with the 1L14 IFF (Identification Friend or Foe) to reduce the chance of friendly fire. The 9P519 grip stock, which also contains the 9B328 power supply unit, is detachable and can be detached from a spent launch tube and attached to a fresh one to launch another missile as long as the power supply has enough charge.
