S-125 "Neva" (export – "Pechora")


		S-125 «Neva» (export - «Pechora»)

Anti-aircraft missile complex C-125 (Sa-3 «Goa» - the US / NATO classification) It designed to destroy air targets at low and medium altitudes. The complex is an all-weather, capable of striking targets on a collision course and in pursuit, in exceptional cases bombard radar observed ground and surface targets. Development of the complex was started in 1956 g. KB-1 (now the "Diamond"). A general designer. Raspletin. Surface-to-air missile was developed by KB "Torch", Chief Designer II. Grushin.

Complex tests began in 1961 city, at the same time he was adopted by the Air Defense Forces of the Soviet Army. At the same time, the Navy ship variants complex Ml «Wave" have been developed (SA-N-1A) and Ml «Wave M" (SA-N-3). A two-stage solid propellant rocket 5V24 formed by normal aerodynamic scheme. its mission is controlled by commands, formed missile guidance station and transmitted over the radio link control aboard. The missile has a solid fuel booster engine, time work is to drop - 2,6 from. Boosters as solid-, started after the end of the start up and running 18,7 from. After resetting the booster rocket begins to take guidance control commands to the meeting point with the aim of. First stage (booster) represents a propellant jet engine TX-36 (14 the propellant sticks of total weight 280 kg). The engine of the second stage represents a weight checker powder 125 kg. Warhead high-explosive 4G90, with ready submunitions weight 60 kg (32 kg - explosive and 22 kg - submunitions). The rocket used Doppler fuze.
The radius of the flight of the fragments of an F-4 targets is 12,5 m. The missile has a fuze, Removing the first protection stage which is carried out after, like a rocket to retire 300 m from the launcher. If the rocket did not hit the target, it self-destructs.

AT 1964 g. adopt new missile 5V27 was adopted. It differed from the previous design of the main engine and had a new, more powerful warhead 5B18 weight 72 kg. Due to this increased missile speed and the size of the affected area.
For the detection and tracking of aircraft targets, and also to transmit control commands to the missile guidance serves ZUR station CHP-125, which operates in the wavelength range 1 (8.9-9.46 GHz). It has a special configuration of the antenna, arranged so, to reduce the influence of reflections from the ground. The maximum range of target detection 110 km. Beamwidth antennas 12 ° x 1.5 °. Antennas have mechanical beam scanning device, that allows simultaneous viewing of a certain area of ​​space. CHP allows you to simultaneously direct the target one or two missiles. To be able to work in conditions of interference station is equipped with an optical television camera, which allows to detect targets at ranges up to 25 km, as well as control of fire. launchers 5P71 or 5P73 used in the complex. On one launcher 5P71 located 2 developing countries, PU 5P73 – 4 developing countries. loading time – 1 min. For transport and loading missiles used freight loading vehicle based on a truck terrain Zil Zil-131 or-157 (earlier versions). Features rocket and warhead can produce fire as a land, and surface radar observed targets.

For purposes of early detection of the division P-125 "Neva" included two coordinate circular scanning radar P-15 P-range (810-950 MHz). It has two arranged one above the other and parabolic antenna beamwidth in the vertical plane 5e, and horizontal - 2 ° Many divisions equipped with radar P-15M, which is characterized, that the antenna can be mounted on the tower height from 20 to 30 m. This increases the range of detection of low-altitude targets. To determine the height of the tracked targets using radar altimeter PRV-11, operating in E-band (2,5-2.7 GHz). The maximum detection distance is 180 km, the maximum detection height - 32 km.
The first combat use of the complex is registered in 1970 g. In Egypt, a cover for the Suez Canal zone and other important administrative centers have been deployed 18 divisions. Prior to the UN Truce, concluded in the same year, via S-125 was downed 5 aircraft type "Phantom» F-4A.
The main battle took place in a complex test 1973 city, when Syria and Egypt were used against a large number of complexes Israeli aircraft. By the beginning of the war the Egyptians were 146 anti-aircraft missile battalions, wherein about a third of them were P-125. During this war, the Arab defense spent 2100 C-75 missiles, C-125, "Square". They were shot down 46 Israeli planes, and 6 of them - the C-125 complex. During the war, some complexes were captured intact by the Israelis and transferred to American experts for detailed study.

FROM 1973 g. C-125 used by the Armed Forces in Iraq (during the Gulf War of 1980-1988.), Syria (for defense Bekaa), Libya (to reflect the US Navy and Air Force air raids in 1986 city), Angola (to deal with the South African aviation). The complex was used as the Armed Forces of Iraq during the Gulf War of 1990-1991.
8 battalions of S-125 were used for the defense of Belgrade in the reflection of NATO air strikes against Yugoslavia. According to some sources,, namely via C-125, equipped with thermal imaging company "Philips", It was shot down by an invisible aircraft F-1I7.
S-125 was exported to many countries: Afghanistan, Angola (3-SAM), Algeria (5), Bulgaria. Hungary (6), Vietnam (40), Egypt (55), Yemen (3), India (12), Iraq, Korea (8), Cuba (12), Libya, Had (3), Mozambique (3), Peru (2), Poland, Syria (40), Tanzania (5), Czech Republic, Finland (3), Ethiopia (8), Yugoslavia (8). For export complex sold under the name "Pechora".
In Russia he was withdrawn from service, but in many countries it remains in service.
