Compared with the portable air defense missile system “Arrow 3” the probability of hitting one rocket of the F-4, flying at a speed of 310 m / s, when firing meet increased from 0,09 to 0,59, vdogon (at target speed 260 m / s) - from 0,07 to 0.44. The maximum speed of the targeted objectives increased from 310 to 360 m / s when firing towards, from 260 to 320 m / s - in pursuit. The upper boundary of the affected area increased from 2200 to 2500 m.
In order to improve the dynamics of missiles pointing at forestalling meeting point for the purpose of additional schemes have been introduced into the heat seeker, generates a command for turning the rocket in the initial phase of flight, and an electronic switch Modes “vdogon-meet”. To ensure poslestartovogo turning miniature pulsed solid-engines were installed in the steering compartment missiles. The missile is aimed at the purpose of the method of proportional convergence. 9K310 Serial production of combat weapons complex was carried out at the Kovrov plant them. AT. L. Degtyareva.

MANPADS "Igla-1" consists of combat equipment (9P322 launcher tube with trigger 9P519-1 and surface-to-air missile 9M313), Means reconnaissance and target acquisition (portable electronic tablet 1L15-1 and ground radar interrogator 1L14-1), communications (station P-157 and P-157P receiver). For maintenance checks and parameters antiaircraft missiles and trigger device maintenance means used, including a movable control station 9V886 and a set of test equipment for bases and arsenals 9F387M.
To prepare gunners are training aids, including field simulator gunners 9F634, training-practical set 9F634, Start monitoring kit. SAM 9M313 performed but the aerodynamic configuration "duck" and represents the body of a cylindrical shape with a spherical fairing. To reduce the aerodynamic resistance in front of the thermal GOS was placed a small cone fairing, mounted on three inclined rods, forming a kind of "tripod". The rocket consists of four sections held together - the brain, steering, combat and propulsion. The missile is based centering collar, determining the caliber, internal pipe wall.

The head compartment located missile tracking purpose coordinator (SKC), command generating device (CRM), electronic part (amplifier) autopilot, Gyro rotor speed stabilization system, photodetector cooling system. As used photodetector cooled to a temperature of -200″ With the photocell based on indium surmyanistogo, the maximum spectral sensitivity of which lies in the range 3.5-5 .mu.m. For cooling these photoconductors using compressed nitrogen. Deep cooling photoresistor possible to increase sensitivity to radiation TGSN jet engine gas jet and reduce the sensitivity to reflected solar energy.
Steering compartment designed to accommodate elements missile power supply, avtonilota and switching elements. The steering powder compartment housing has a pressure accumulator (UNDER), providing food hot gases servo, and turbo-generator, converts the energy of the hot gases into electricity PAD, regulator rectifier, providing rectification and stabilization of the supply voltage, The angular velocity sensor with amplifier, servos with rudders, block cocked, forming a signal to electric igniter fuze after rudders disclosure and electric igniter powder control motor, bortrazema socket, provides electrical communication equipment onboard the rocket from the launch tube.

The rocket engine control powder is set, generating hot gases for a gas-dynamic missile flight control in the initial portion. Combat compartment is a carrier rocket and the compartment is made as a permanent connection, comprising warhead, fuse, explosive generator. Warhead high-explosive-cumulative actions designed to destroy air targets and consists of a body with a cumulative funnel, combat (discontinuous) charge and detonator. The warhead explosives used with increased explosive effect. Fuse for issuing a pulse detonation undermining warhead when the missile or meeting to but after a time of self-destruction. Fuse, Besides, It transmits pulse detonation of the warhead charge to the charge of explosive generator.
Slam-detonating device is used to provide security in the handling of the missile until it is charging after missile launch. It includes a pyrotechnic fuse, spigot and blocking (inertial) stopor.Vzryvnoy generator is configured to generate a pulse for detonation of the detonation of the fuel charge of the propulsion system and the creation of additional field defeat.
The pipe is designed for aiming, missile launch and Prevention gunners from influence of powder gases start the engine at start. At the same time it serves as a seal for the rocket during transportation, transportation and storage, as well as a guide for rocket launch. In operation, the missile from the tube is not extracted and leaves the tube only at start.

Pipe MANPADS "Igla-1" made of fiberglass. It includes: rotation unit, mechanical sight, bortrazema mechanism, Socket for docking trigger, Block connections starter motor zonal chains, clip fastening the shoulder strap. the rotation unit is mounted on the front part of the tube and, together with the acceleration and synchronization unit is designed to trigger acceleration gyro rotor TGSN. On rotation of the pipe block mounted antenna ground radiozaproschika. Since the pipe allow reuse, the number of red bands, deposited on the sensor unit, It indicates the amount of products produced from a given tube missile launches. Mechanical sight consists of reclining front and rear pillars and designed for aiming. The front desk fixed front sight with a hole. The rear pillar rack arranged with the light information lamp, sunbathing which indicates the purpose of radiation released into the field of view TGSN, and the diaphragm, which closes the lamp during start twilight avoid glare gunners.
The front and rear sections of the pipe are closed easily removable lids. The front cover has a magnetic circuit (metal ring), It is a detent rotor magnet. The trigger mechanism is designed to prepare for the launch and missile launch. The trigger is embedded requestor 1L14-1, providing identification purposes and automatic lock start-Zour on his plane. However, due to the large width of the antenna pattern, as well as because of the rear lobe of this diagram, the interrogator can work from the defendant of his plane, flying near a portable SAMs, and block the launch of the enemy. In such cases, the shooter can disable the startup lock.

Portable electronic tablet 1L15-1 for timely notification gunners on location, direction and gosprinadlezhnosti ("Friend or foe") aerial targets. The plate is capable of displaying traffic situation in the radius 12,8 km. The number of simultaneously displayed purposes - 4, the maximum distance to the information transfer point - 15 km. source of information for the tablet may be air defense command and control centers in the link “division-regiment”. Produced modification "Igla-1E" and "Igla-1M", characterized in, that fuel residues at undermining warhead is not undermined. Besides, "Igla-1M" had no radar interrogator, a “Igla-1E” I had an interrogator with the parameters, identify the country of the customer. AT 1982 g. tests were carried out complex "Igla", which was adopted in 1983 g.
MANPADS is a further development of the complex “Igla-1” and differs from the latter to improve efficiency through the use of dual-channel seeker 9E410, developed by JSC “LOMO” (Chief Designer Head On. L. Artamonov). Homing head is able to distinguish between true and false targets in setting conditions of jamming in the infrared range. GOS has a high sensitivity, which increases the range of shooting at targets on a collision course. Heat seeker 9E410 has two channels - the main and auxiliary. Photocell main channel is based on the photoresistor indium surmyanistogo, cooled to a temperature -200'S. The cooling system of the photodetector is the same, like 'Needle-1 ". The maximum spectral sensitivity of the photodetector fundamental channel is in the range 3.5-5 .mu.m, which corresponds to the spectral density of the gas jet engine strings radiation.

Auxiliary channel photodetector is a photoresistor uncooled based on lead sulfide, the maximum spectral sensitivity of which lies in the range of 1,8-3 microns, which corresponds to the spectral noise density of radiation such as false heat goals. The circuit switching GOS 9E410 decides according to the rule: if the signal level of the photodetector base channel more than in the auxiliary channel signal, this goal, if on the contrary - a hindrance. Applying new thermal GOS allowed to use not "tripod" for reducing the aerodynamic drag, used on the missile complex "Igla-1", and a needle-like structure graceful.
The complex provides defeat of air targets on a collision course and will catch up, fires back with time intervals of 0,3 and with a thermal noise in excess of the cash of the total radiation power of the radiation power of the target up to six times. When shooting of the objectives of thermal noise on a collision course and will catch up with single or bursts (up to six in the volley) the average probability of hitting the target of one SAM 9M39 overflight of the affected area was 0,31 when firing meet and 0,24 when shooting in pursuit. In such conditions, interference complex "Igla-1" was practically unworkable. Later, mainly for Airborne. a portable version of SAM was developed “Needle-D” with SAM and launcher tube, which is transported in the form of two sections, connected to the combat use. This has improved “desantiruemye” complex and to ensure ease of carrying.
It was also designed unit, providing the use of two missiles in launch tubes, for use in land-based launchers and helicopters as weapons in the complex "Igla-V".
To ensure the simultaneous application of two SAM developed version of the complex to the turret ("Dzhigit"), wherein antiaircraft arrows be stirred in a rotating chair, and manually performs guidance launcher at a target.
Meanwhile addition, a portable version of SAM was developed “Needle-N” with a purse warhead. Complex supply grew by 2,5 kg. Due to a slight reduction in these indicators, as the speed of the targeted objectives on a collision course and will catch up (to 340 and 280 m / s, respectively,), probability of defeat purposes increased by 25-50%. portable air defense missile system “Igla-1” exported abroad, used in local fighting.
