Chernobyl - 2, aka Duga "Doug"
Material posted : Administrator Publication date: 27-04-2015
Near the Chernobyl nuclear power plant (Ukraine) has an interesting object, which can be seen from Pripyat. It turns out the so-called Chernobyl-2 ... The object is called "Arc", he worked for several years. Construction of the plant at Chernobyl was completed in 1975. After the events of April 26, 1986 the station was frozen and operation terminated in connection with possible damage to electronic equipment. For the characteristic sound of the air produced when (knocking) was named Russian Woodpecker (Russian Woodpecker). Height station near Chernobyl about 150 meters, the length of 800 meters.

The experimental knot «Chernobyl-2 ″ was superconfidential installation and on all topographic maps of that time, between villages Diggers and Dibrova where was RLS, there was a point which has been marked out as« pioneer camp ”.

In 1947 the research assistant of scientific research institute-16 Nikolay Ivanovichem Kabanovym in the world had been put forward for the first time idea early (zagorizontnogo) detection of airplanes in a short-wave wave band on removal to 3000 km. At the heart of idea use of effect of reflexion of radio waves from an ionosphere for zagorizontnogo detection of the purposes lay. The altitude of ionised regions of an aerosphere from which the radar station beam (RLS) is reflected, makes from 70 to 300 km; at one reflexion, taking into account curvature of globe, the beam will fall to a terrestrial surface just on such distance (to 3000 km). The stations built counting on such process, are called odnoskachkovymi. If it is necessary to "look" further the station (two - tryohskachkovye is required mnogoskachkovaja).

Within the limits of Research work (NIR) "Fan" in Mytischi the pilot plant has been built, but to detect the purposes behind horizon because of N.I.Kabanovu's insoluble technical difficulties at that time and it was not possible. Therefore the opinion was installed what to detect the purposes behind horizon against powerful ground echoes it is impossible. NIR "Fan" has been finished in 1949
Works on zagorizontnoj radiolocations in the USSR have renewed in 1958 During works basic possibility zagorizontnogo detection of airplanes at range of one jump (3 000 km) and starting wingless missiles at range of two jumps (6 000 km) has been proved.
Practical implementation zagorizontnoj locations in the USSR is connected with a name of the chief designer of radio-relay lines, the winner of the State bonus of the USSR Efim Semenovicha Shtyrena. It, without knowing about opening of Kabanova, in the late fifties has made the same proposal for detection of airplanes at ranges 1000 - 3000 km.

Efim Shtyren, its proximal assistant and adherent Vasily Shamshin (become subsequently the Minister of Communications of the USSR), young scientific Efir Shustov and Boris Kukis have theoretically proved possibility of creation powerful short-wave zagorizontnogo a radar. They have developed the scientific report "Arch" named so because detection of the purposes for thousand of kilometres went over a round surface of the Earth. On January, 1st, 1961 the report on NIR "Arch" in which results of calculations and experimental researches on reflecting surfaces of airplanes and rockets, and also a high-rise trace last were fixed has been delivered, and the method of allocation of a weak signal from the purpose against powerful reflexions from a terrestrial surface is offered. The commission, having observed the report, has stated work a positive estimation and recommended to confirm theoretically well-founded possibility of detection with direct experiments.

Steady perfection of wingless missiles (BR), increase in their quantity at the probable opponent and cool relations between the USA and the USSR have led to emersion of real threat of a rocket attack to Soviet Union. The party leadership and the countries realised it, therefore decisions of the Central Committee of the CPSU and Ministerial council of the USSR «About creation of a warning system and a target designation of system IS, warning facilities about a rocket attack and an experimental complex of means of long-distance detection of starts of wingless missiles, atomic explosions and airplanes outside of horizon» and «About creation of domestic control service of an outer space» on November, 15th, 1962 have been signed. Undoubtedly, these decisions had been opened a new survey stake in the field of control air and an outer space.

In the USSR have been opened row NIR and OKR (development engineering) on formation and escalating of a group of means of early detection of starting intercontinental wingless missiles (MBR).

To one of these decisions to Research institute of a long-range radio communication - scientific research institute GIFT (F.V.Lukin, E.S.Shtyren) has been charged NIR "Duga-1" on creation zagorizontnoj RLS.

In August, 1964 after discussion of a condition and prospects of works on NIR "Duga-1" on scientific and technical council of scientific research institute GIFT with the chief engineer of institute appointed by then F.A.Kuzminskim it has been decided to report this question on the minister of the radio industry V.D.Kalmykovu.

At meeting were present G.P.Kazansky (the first deputy of the minister) and academician A.L.Mints. Kazan has stated the careful point of view: still there are not enough initial data, it is necessary to continue experimental works. On it Minz has objected: «We have started to design in due time a synchrophasotron, without having the task and without knowing, as to it to approach. It is impossible to oppose research and engineering-design works».

Having listened to all pro's and con's, V.D.Kalmykov has told: «the Problem of the early forestalling for our country is extremely important. We have no baselines near to continent USA to detect MBR from the moment of their start. Therefore, despite lacking many initial data, it is necessary to run risks and create development type ZGRLS in Nikolaev. I oblige you to develop in 1965 avanproekt this radar set and to get down to engineering specifications working out on equipment, that is to pass to OKR».

The complex of works on NIR "Duga-1" of scientific research institute carried out GIFT on experimental installation which have mounted around Nikolaev (nearby with. Kalinovka). In 1964 it has marked for the first time the rocket starting from Baikonur, at range of 3000 km.

After end NIR of "Duga-1" in 1965 in scientific research institute GIFT have got down to a following stage of works. On the same place, in Nikolaev creation of new development type RLS has been co-ordinated with the Ministry of Defence and the Commission on military-industrial questions zagorizontnogo detection BR.

On June, 30th, 1965 the Decision of the Central Committee of the CPSU and Ministerial council of the USSR of scientific research institute GIFT had been set creation of skilled devided out sample ZGRLS of "Duga-2". Development type ZGRLS of "Duga-2" has gained the code number 5Н77. In 1966 the chief designer of development type ZGRLS had been appointed V.P.Vasjukov.
In 1966 outline sketch ZGRLS in which have been defined composition and characteristics of the devided out development type zagorizontnogo a radar set has been developed. Questions of external cooperation have been solved. The Leningrad branch TSPI-20, Spetsstalkonstruktsija and KB have been involved in designing of antenno-feeding devices (AFU) of A.A.Raspletina; power amplifiers - KB of the Leningrad factory it. Of Komintern, OKB DMZ; equipments of search of working channels - the Leningrad scientific research institute "Vector". Other equipment developed and made in scientific research institute-37 (since March, 24th, 1966 Research radio institute (NIRTI), since November, 25th, 1975 - scientific research institute GIFT (Research institute of a long-range radio communication)). The Head technological factory has been involved In montazhno-adjusting works (GPTP) from Moscow.
In the same 1966 around Nikolaev there are begun civil work of skilled devided out sample ZGRLS 5Н77 by "Duga-2". The reception centre of radar-tracking knot with ZGRLS 5Н77 "Duga-2" was about Nikolaev (with. Kalinovka), a transmitting centre - about the item the Beam on boundary line of the Nikolaev and Kherson areas.

The reception is antenna radar-tracking knot with ZGRLS 5Н77 "Duga-2" about Nikolaev (with. Kalinovka):


Without expecting end of tests of skilled devided out sample ZGRLS 5Н77 "Duga-2" in Nikolaev, in 1969 the solution on system creation zagorizontnogo detections of ballistic missiles (BR), consisting of two more perfect ZGRLS, arranged around cities of Chernobyl and was accepted Komsomolska-on-cupid. At the coordination of technical requirements chief designer F.A.Kuzminsky, leaning against the positive data gained on the Nikolaev installation (which has been orientated on a middle-latitude route to China), has accepted for these ZGRLS the overestimated demands on probability of detection single and multiple targets at range of 9 000 km (new ZGRLS should be orientated through an arctic pole to the North America). The underestimation of agency of a polar ionosphere prized subsequently on attenuation of a signal and an existence time of "long-range signals» on these routes has been thus admitted.
On September, 29th, 1969 the Decision of the Central Committee of the CPSU and Ministerial council of the USSR of scientific research institute GIFT had been set working out of head Radar-tracking knot (RLU) № 1 with ZGRLS 5Н32 "Arch".

The scientific research institute GIFT in 1971 has been developed outline sketch ZGRLS 5Н32 and avanproekt systems on the basis of ZGRLS 5Н32.

In 1972 in the USSR the concept of the integrated system (IS) forestallings of a rocket attack has been developed. It included both built and under construction, and installations of system of the forestalling of a rocket attack assumed to building (SPRN). Concept IS included land nadgorizontnye and zagorizontnye RLS and space means. Ability to provide otvetno-encounter attack implementation was primary goal IS. For detection of start-up MBR in a propagation time them of an active phase of trajectory that would provide the maximum time of the forestalling, it was supposed to use companions SPRN and ZGRLS. Detection of battle units of rockets on late sections of a ballistic trajectory was provided by means of system nadgorizontnyh RLS. According to development engineers of the concept, such separation considerably raised system reliability and reduced probability of errors as for detection of a rocket attack different physical principles are used: Registration of caloric radiation of the working propeller starting MBR satellite sensing transducers and registration of the reflected radiosignal by means of RLS.

Concept IS has been issued on January, 18th, 1972 by the Decision of the Central Committee of the CPSU and Ministerial council of the USSR. The decision with a view of creation complex SPRN had been set building of knot of early detection № 5 (РО-5) with RLS "Dnepr" in Mukachevo, knot РО-30 with RLS "Darjal" in Pechora, knot РО-7 with RLS "Darjal" in Mingechaure, two knots zagorizontnogo detection with ZGRLS "Arch" in Chernobyl and Komsomolske-on-cupid, the taken out reception of a position "Daugava" on knot РО-1 in Murmansk and creation of Command point (KP) Systems of the forestalling of a rocket attack (SPRN) on the basis of Command point of early detection (handheld computer RO) in Solnechnogorske.

Thus, RLU № 1 ZGRLS 5Н32 "Arch" around Chernobyl and RLU № 2 ZGRLS 5Н32 "Arch" around Komsomolska-on-cupid (both with orientation to the North America through an arctic pole), and also the taken out reception of a position "Daugava" about Murmansk, on knot РО-1 of system SPRN, should provide reliable detection of group and mass start MBR from territory of the USA.
In March, 1972 about Chernobyl there has been begun building head RLU № 1 with ZGRLS 5Н32 "Arch".

The first series of electromagnetic translations has begun with this installation on July, 4th, 1976. These translations disrupted radio communication on all planet over the range from 3 to 30 Mgts. Pulses were transferred with an interval in the one tenth seconds. The signal was displaid not only special equipment, but also was audible in usual radioreceivers, as pulsing knock.

In assemblage of the countries of the world on «Russian Woodpecker» thousand complaints from the companies and simpl radio fans were strewed. As «Russian Woodpecker» knocked on the frequencies guarded by the international agreements for civil using, the government of the USA, Great Britain and Canada have made a protest to Soviet Union. But the USSR did not admit even the fact of existence of the Woodpecker. The world community of radio fans even has made an attempt suppression of Russian Woodpecker, having tried to broadcast in phase opposition square pulses on the same frequency to prevent the Soviet woodpecker-receiver. However and this trying has not crowned success.


As to appointment of Russian Woodpecker then there was a weight of theories. So, even the control theory was at the highest level observed by consciousness. One of consultants of the Ministry of Defence of the USA wrote: «the signal of Russian Woodpecker is the most powerful source of electromagnetic radiation ever created by the person. 10 pulses in a second, 40 million Watt, it psihoaktiven! It is radiated from Soviet Union and pronitsaet all in the USA. It is trapped by wires of the network and through them the Federal commission on communication of the USA flows into in our dwellings» In 1988 has investigated and, at last, has found out appointment of Russian Woodpecker. It has appeared that Russian Woodpecker was powerful nadgorizontnym a radar of the Soviet system of the forestalling of a rocket attack (SPRN). It traced a behaviour of the ionosphere which originate at turning on of rocket engines (effect of a de-ionisation of an ionosphere and decrease in reflectivity of radio waves of the Kv-range).

The western special services actively studied other possible effects of act of "Russian woodpecker” from change of weather and before destroying agency on consciousness of people, seriously observing «Russian Woodpecker”, as the experimental weapon of the USSR. Such assumptions were quite proved as already many years were conducted researches of every possible affectings of a powerful electromagnetic radiation. For example, at the beginning of the century experiences of scientist Tesly on wireless transfer of electric energy have led to infringement of power supply and hundreds forest fires because of the burst thunder-storms. In 1978 the log "Spekjula" has published the data of researches which have shown that electromagnetic signals of certain frequencies can be transferred through thickness of land. Entering into its surface at an angle 30 grades, they form standing waves which to develop with the waves radiated by the fused kernel of the Earth in the heart of land that as a result can lead to earthquakes and atmospheric storms.

Under the available information, in Norway the powerful sender which electromagnetic radiation could create nonlinear effects in an ionosphere, preventing normal operation of knots of the Arch has been installed.

Transfer zagorizontnymi RLS the signals, capable to influence mentality of people was other direction of researches. The idea essence consisted that the high-frequency signal was used zagorizontnymi RLS as carrying. It was modulated with other signal of ultralow frequency which coincided with frequencies of pulses of the brain which is in a condition of depression or irritations. Such over low-frequency signals, were displaid and deposited from signals zagorizontnyh RLS the USSR in territory of many western countries. Such signals were classified as psychoactive and capable to influence behaviour of people.

The front pages of the western press of that, a time dazzled with such titles: «Russian are on the threshold of opening of new production engineering and armament which will leave in the past of the rocket and bombers. This production engineering will allow them to destroy to five American cities in day by means of translation of wireless pulses. They can carry a panic and sicknesses to the whole people.”

Data of the Soviet survey confirmed that similar works were conducted also by Americans. The American analogue of "Russian woodpecker» was called "Circular saw". "Circular saw" could radiate a psychoactive signal which co-operated with a brain of the person, being as though imposed for its work. Active works were conducted on decrease of sizes of "Saw", for reception of mobile installations which could be installed by helicopters, tanks and other military technology.

Building of station near to the Chernobyl atomic power station spoke its high power consumption. Originally the radar of radar-tracking knot often named «Chernobyl-2 ″, worked on frequencies between 3.26 and 17.54 Mgts. With the beginning of work of station, its sender has started to block frequencies of communication and the frequencies intended for work of aircraft. Subsequently the radar has been inoculated so that began to pass these frequencies, moving the sector of detection.

Possibilities to muster station on starts of the Soviet rockets were not, as the antenna has been directed strictly to the North America. Therefore testing was conducted on educational starts "Trajdentov" from the American submarines in Caribbean sea, starts of "shuttles" and even on meteorites. The station was capable to detect start KR "Tomahawk" from a nuclear-powered submarine in Atlantic ocean.

In classification of the NATO these RLS were known code-named - «Steel Yard».

The information with «Chernobyl-2 ″ was constantly transferred to command point though the installation on high-grade battle watch never was, changes on duty took up also work was conducted round the clock. Including the exploratory.

In 1972 in the USSR the concept of the integrated system of the forestalling of a rocket attack has been developed. It included land nadgorizontnye and zagorizontnye radar stations and space means and was capable to provide otvetno-encounter attack implementation. For detection of start-up MBR in a propagation time them of an active phase of trajectory that would provide the maximum time of the forestalling, it was supposed to use companions SPRN and zagorizontnye RLS. Detection of battle units of rockets on late sections of a ballistic trajectory was provided by means of system nadgorizontnyh RLS. Such separation considerably raises system reliability and reduces probability of errors as for detection of a rocket attack different physical principles are used: registration of caloric radiation of the working propeller starting MBR satellite sensing transducers and registration of the reflected radiosignal by means of RLS.

Building first RLS the early forestalling was conducted in 1963-1969. It were two RLS type "Dnestr TH", placed in Olenegorske (Kola peninsula) and Skrunde (Latvia). In August 1970 system has been taken into service. It has been counted for the detection of ballistic missiles, the USA launched from territory or from water areas of Norwegian and northern seas. Giving of the information on a rocket attack for system of the anti-missile defence developed round Moscow was the primary goal of system at the given stage.
In 1967-1968, simultaneously with building RLS in Olenegorske and Skrunde, there has been begun building of four RLS type "Dnepr" (modernised version RLS "Dnestr TH"). For building knots in Balkhash (Kazakhstan), by Mishelevke (near Irkutsk), Sevastopol have been chosen. One more has been built on knot in Skrunde, in addition to already working there RLS Dnestr TH. These stations should provide wider field of view of system of the forestalling, having expanded it to Northern Atlantic, regions Silent and Indian ocean.

Developed in 1972 concept of system of the forestalling of a rocket attack provided integration with existing and again created means of anti-missile defence. Within the limits of this program "Danube-3" (Cuban) and "Danube-3U" (Chekhov) of system of the ABM of Moscow has been switched on in forestalling system RLS.

Except the termination of building RLS Dnepr in Balkhash, Mishelevke, Sevastopol and Skrunde has been planned creation new RLS this type on new knot in Mukachevo (Ukraine). Thus RLS Dnepr should become a basis of new system of the forestalling of a rocket attack. The first stage of this system into which composition entered RLS on knots in Olenegorske, Skrunde, Balkhash and Mishelevke, has begun battle watch on October, 29th 1976. The second turn into which composition entered RLS on knots in Sevastopol and Mukachevo, has been put on battle watch on January, 16th 1979.

The station in Komsomolske-on-cupid on knot «″ after considerable finishings is put Duga-2 on battle watch on June, 30th, 1982. It provided coverage of Pacific ocean to territory of the USA. Now RLS it is removed from battle watch.

Owing to low efficiency dvuhskachkovoj zagorizontnoj radiolocations in second half 1980 there is a question on expediency of use on direct appointment of knot «Duga-2 ″ and in 1987 knot problems are specified. In the early nineties on knot there was a fire owing to what the station has stopped the operation in composition SPRN.

At maintenance zagorizontnyh RLS in conditions severo-shirotnyh routes MBR passing through an arctic pole, with constant chaotic perturbation of an ionosphere their separate deficiencies were found out, in particular, RLS could detect only mass start MBR and with some restrictions. Therefore, these knots have not been taken into service. The general expenses on them have made an order of 600 million roubles.


Design ZGRLS of "Duga-2" is observed and approved by the State commission (chairman J.V.Votintsev) and recommended for instalment implementation. The solution on building is accepted in 1969.

For building ZGRLS, have originally chosen a place near Dymera in the north of the Kiev area, then have changed the solution. On hearings, the first secretary of Communist Party of Ukraine Vladimir ShCherbitsky has insisted, that a platform have taken away on poor polesskih lands. For the personnel have built the whole small town.

The first results of tests of station in Chernobyl in a direction severo-shirotnyh routes have appeared unsatisfactory. Because of strong perturbations of an ionosphere, presence of polar caps and other adverse conditions in subpolar and polar regions the probability of detection of single and group starts of rockets has appeared very small (0,1-0,2 for single and small groups of rockets, and their mass starts - 0,7). Therefore the knot of Ljubech-1 has been refunded on finishing. On it the so-called "polar" honing program was carried out. Development engineers approved that results of honing works were positive.

As a part of system "Дуга-2" creation of two knots on the basis of powerful RLS ZGO was provided. The first knot (western) was supposed to be developed around Pripyat - installation 2999, the NATO designation - «Steel yard” (steel yard).

Chernobyl-2 was served VCH 74939, and by Ljubech-1 VCH А3330.

The second knot (east) - near settlement Big Cartel (Komsomolsk-on-cupid, Khabarovsk territory) - installation 1937.
The chief designer of a product 5Н32 "Duga-2" (in an aftereffect indexation system have replaced, the code number became - 32Д6) - Kuzminsky Frants Aleksandrovich.

The computer system had the code number 1С31Г.

COMPUTER K-340A for signal machining was made on discrete components.


In Ljubeche and in Chernobyl there were two lattices - one big, second it is less. Probablly, smaller worked on a high-frequency unit of a range of station, big on a low-frequency unit of a range.

Antennas under Ljubechem were well visible from roofs 9 floor buildings of a city of a Slavutich. From Chernobyl atomic power station to ZGRLS have conducted an electric main. Energy moved and from LEP, going from Kiev. Power of senders in Ljubech-1 - to 8 Megawatt pulsing (to 400 KW in conversion on average for a sinusoidal source). Because of such huge power, some workers in Ljubeche even fixed knock of a woodpecker without additional devices, own organs of touch.

On production engineering of maintenance AFU, painting of a product of times in 5 years in alternating strips red and a white has been assumed. The first painting has been carried out by climbers in the summer of 1980. Designs AFU have been made on GOMSELMASHE of a high-alloy steel and in the same place are zinced. Tower installation in Ljubech-1 conducted SMU - 168 "Radio systems" with use of the assembly crane, altitude under 200 metres with an express lift.

The transferring equipment collected on Dnepropetrovsk engineering works and consisted of 26 senders, the size of everyone was about the two-storeyed dwelling.

On distance about 2 kilometres to the west from the big antennas of Chernobyl-2 there was a design of antennas in diameter of 300 metres and altitude 10 m - two concentric circles with a single-storey building in the centre (240 vertical volume dipoles - 2 circles on 120 dipoles - internal and external and between them the shield). Between village Korogod and small town Chernobyl-2, there goes betonka. Turn in front of the big antennas on the left (to the right-Chernobyl-2).


It is so-called HONEYCOMBS (system of definition of a route) - station of vozvratno-inclined ionospheric sounding for definition MPCH. The ring lattice, allowed to define a direction of arrival EM of a wave and quality of extending. But it did not carry out the mission, and was used periodically for conducting every possible eksperementov, for example, passive radiolocation over the range SQ.
Between circle and antenoj Chernobyl-2 still was installation TSKS (the space communication centre).

The installation «Chernobyl-2 ″ as a unit of system anti-missile and protivokosmicheskoj defences of troops of air defence has been conceived for nuclear attack detection to the USSR first two-three minutes after start of wingless missiles. From America to the rocket Union 25-30 minutes would fly, and it was possible to have time to accept counter-measures. By means of the short radio waves, capable to be passed round to thousand kilometres, was volplaned to scan territory of the United States constantly. The sender arranged in 60 kilometres from the antenna near Chernobyl, in the Chernigov area, should send high-power pulses which through Northern Europe and Greenland reached the USA and were refunded back. Them trapped the antenna« Chernobyl-2 ″, and processed by means of computers.

Write that in the beginning of 1986 knot Ч-2 has detected both start, and explosion of a shuttle "Challenger" launched from the western range USA on distance of 9000 km from ZGRL. If only at station the information on start-up have not gained from messages by vision. The shuttle has blown up on January, 28th, 1986 on 73 second after start. An effective reflecting surface in this case, was a little. However, during this period the new equipment was installed. Calculation has gained an estimation for this watch 5.

After catastrophe

After catastrophe on the Chernobyl atomic power station (April, 1986) the knot of Ljubech-1 which have appeared in 30 km to a zone of alienation, has been laid up, and in 1987 the solution on its closing was accepted.

About 11 o'clock in the morning on April, 26th, 2006 the commander of a complex Vladimir Musiets has disposed to disconnect installation - the ventilation system sucked in radiation together with air. Civilians of small town Chernobyl-2 evacuated this very day, as Pripyat … After crash on CHAES «Chernobyl-2 ″ never worked. Though about its closing have started talking only in one and a half year after. The first trying of a decontamination have undertaken in the beginning of June, 1986. Then the team of the chemical protection which have arrived from the Leningrad military district, three days washed installation and small town, removed strongly low-purity turf. But soon the radiation level was rebuilt. Later the attention to the question on a housing construction in new small town energetikov a Slavutich that the personnel could work vahtovym as a method was brought. Within 1986-1987 rabotiki stations by own strength repeatedly tried to conduct a decontamination. The territory has not been licked almost, but it did not help. Further, the equipment unit has been taken out/is destroyed by military men, the rest was taken away on precious metals in the first years after crash by the "collectors", by some, gave out itself for liquidators and with counterfeit deeds and a tool set made the way in a zone and broke completely equipment Ч-2.

The antenna in Ljubech-1 demounted somewhere around 1998-2005. The bulk of support have taken away on metal. Some pieces managed to be kept, one of them is mounted in Dnepropetrovsk, second is probable in Izmile, in the capacity of a television tower, in a little truncated aspect, on 15 metres more low.
