Minelayers and minesweepers. The last anti-mine ships of the sea zone of the Soviet Union

10.10.2020

The first domestic post-war basic minesweepers of projects 254 and 264 were significantly inferior to their foreign counterparts in terms of the level of their physical fields. Therefore, in the 50s, the Navy carried out intensive development work (R&D) in the field of protecting minesweepers from mine explosions in three main areas:
- early detection of a mine ahead of the course of the minesweeper in order to avoid meeting with it;
- lowering the level of physical fields of ships to a safe level;
- increasing the explosion resistance of ships.
As it turned out, sufficient reliable detection of anchor mines ahead of the course is possible with the help of high-frequency hydroacoustic stations (HAS) for mine detection, while their use significantly increases the productivity of mine reconnaissance. and was put into service in 1959. GAS MG - 59 had excessively large dimensions, they refused to use it on serial ships of projects 254 and 264, but on its basis the GAS Lan (MG - 69) was created, providing , reliable detection of anchor mines at distances of 1000 - 1100 m.
Work to reduce the physical fields of minesweepers has been carried out since the beginning of the 50s. In 1958, the Decree of the Government of the USSR “On increasing the protection and secrecy of naval ships from underwater non-contact weapons” and means of detecting the enemy” was issued. In accordance with this Decree, it was planned to develop measures to reduce the physical fields of minesweepers and requirements for their permissible levels, registration and analysis equipment fields, as well as the creation of special polygons and stands. By the end of the 50s, a special range for measuring physical fields, a range for testing mine weapons, two non-winding demagnetization stations (SBR), three control and measuring magnetic stations (KIMS) and eight hydroacoustic control ships (GCS) were built. In particular, KIMS - 2 (Amur Bay, 2nd River), KIMES - 315 (Russky Island, Novik Bay) were built at the Pacific Fleet.
It was proposed to increase the explosion resistance of minesweepers by strengthening the hull, shock-absorbing protection and the use of shock-resistant equipment.

On the basis of the R&D listed above, in 1956 the Navy issued a tactical and technical assignment to TsKB - 363 (later the Western Design Bureau (PKB), p / box A - 1277) to develop a project for a new generation ship of the base minesweeper project 266, ship 3 rank. Chief designer of the project N.P. Pegov, chief observer from the Navy, captain 2nd rank V.T. Kuzmin. The development of the preliminary design was completed in 1957, the technical design - in 1958. The technical design was approved in 1959.
Project 266 BTS was designed as highly specialized, with new anti-mine weapons, non-magnetic (low-magnetic) and partially noise-free equipment (including high-speed star-shaped main engines of the M503B type), with low-noise controllable pitch propellers (CRP), night vision equipment and sound underwater communication, hydroacoustic station detection of anchor mines, the antenna of which was located in the fairing of the lifting and lowering device (POD). Previously, the project of the ship was developed in two versions: with a low-magnetic steel hull, glued on the outside (according to the original plan) with a 20 mm rubber coating, and with a wooden hull. Already at the initial design stage, the wooden case had to be abandoned due to the lack of the necessary production base in the country, and the project was developed in a case made of Yu3 low-magnetic steel.
In terms of architectural type, the project 266 battleship resembled the similar project 264A, but had a lower displacement (by 320 tons) and a relative elongation (length-to-width ratio) of 5.5 instead of 7.4, as a result of which the ship, with a more powerful energy installation (greater by 1000 hp) had a lower travel speed. One rudder was installed (one rudder blade). To reduce the level of physical fields, numerous measures and devices were provided that were not previously used in the fleet. To reduce the level of the magnetic field and to protect against non-contact mines with magnetic circuit channels, for the first time in domestic shipbuilding, the hull and hull structures were made of low-magnetic steel Yu3. Doors, hatches and their coamings, ladders, railings, numerous fenders, etc. were made of light aluminum-magnesium alloys (AMG). Mechanisms, weapons, devices and equipment were made in a low-magnetic design. Degaussing device (RD) with system automatic regulation contained both general ship windings (main horizontal - OSHT, course buttock - KB, course frame - KSh), and local windings for the main largest mechanisms (OShT, KB, KSh on main engines, diesel generators and auxiliary boiler unit, capstan electric motor ). In addition, a vortex demagnetizer (RUV) was provided with an automatic control system to compensate for the magnetic fields of eddy currents that occur in the ship's hull during rolling, with the main vortex - OV, buttocks eddy winding - BV. To reduce the acoustic field of the ship, the following were used: soundproofing with the help of shock absorbers, pasting with a vibration-damping rubber coating of the foundations of the main mechanisms (GDGD, DGDG, compressor) and bulkheads of engine rooms, soundproofing flexible inserts in pipelines, systems and places of attachment to mechanisms (in particular, shafting to main engine power take-off flange), the use of low-noise large-diameter controllable-pitch propellers with a relatively high speed. For the first time in domestic practice, special measures were provided to reduce low-frequency electromagnetic (exclusion of sacrificial protection, etc.) and electric (dielectric coatings of equipment in contact with outboard water, electrical insulation of bottom-outboard fittings, shafting from the hull, etc.) fields. Trawl and deck mechanisms (winch, view, crane beams) were transferred to hydraulic drives, which, along with ensuring a decrease in the level of the physical fields of the ship, made it possible to obtain mechanisms with a wide range of smooth speed control. Oil was supplied to the hydraulic system of deck machinery from three pumping units, consisting of IID20 pumps with their own electric drives. The steering machine is also transferred to a hydraulic drive with the Albatross control system, which provides for simple, servo and automatic control modes. One rudder was installed.
The main power plant is two-shaft with an echelon arrangement (in two engine rooms) of the main engines of the M503B type with a power of 2,500 hp each. The main engines were powered by BP 266 variable pitch propellers. The propeller pitch was changed by a hydraulic system, the oil supply to which was carried out by electrically driven pumps. The remote control of the GDGD and CPP was provided from the engine control posts and from the GKP. The electric power plant included three diesel generators (~ 380V, 50 Hz) with a total capacity of 500 kW (2x200 kW with 7D12 diesel engines, 1x100 kW with 7D6 diesel engine).

The unsinkability of the ship was ensured by division into 9 watertight compartments.

1 compartment with (-) 5 - 5 frame - forepeak, chain box, paint pantry;
2 compartment with 5 - 13 frame - capstan, artillery ammunition cellar, spare parts storeroom, hold compartment;

Further development minesweeper project 266 received in the project 266M "Aquamarine". It should be mentioned that in the 1960s, the minesweeper project 1251, which is a fiberglass modification of project 266, was developed. The design was carried out by the Western Central Design Bureau. Chief designer D.T. Pokhodun. The technical project was developed, but the construction of the ships of the project was forced to be abandoned due to the unavailability of the production base by that time.

The construction of the project 266 unit was deployed at the Sredne-Nevsky shipbuilding plant (Leningrad, Ponton settlement) and the Khabarovsk shipbuilding plant named after S.M. Kirov (p / box A - 3126) of the Ministry of the shipbuilding industry of the USSR. The introduction of a large number of new technical solutions into the project made it difficult and delayed the construction and delivery of the lead ships to the Navy. Thus, during the construction, the insufficient survivability of the rubber coating of the outer skin of the hull was revealed, the failure of which led to an unforeseen increase in draft and other negative consequences, which required a prompt adjustment of the project during the construction of the ships. Many difficulties arose in the processing of hull structures made of Yu3 low-magnetic steel, which was first used in domestic shipbuilding, and their subsequent welding. This steel had a tendency to crack as a result of stresses arising during processing. The correction of residual deformations that appear during the processing of structures made of this steel by conventional heating and subsequent mechanical action turned out to be unacceptable, since cracks formed, and it was necessary to replace, for example, the whole sheet or part of the sheet according to the size of the residual deformation. Looking ahead, it should be noted that during the operation of the first ships in the construction of the series, a large number of cracks occurred in the hull structures during their processing (gtbk, straightening). Over time, ways were found to combat the tendency of low-magnetic steel to crack. So, in order to relieve residual stresses arising during the processing of structures made of this steel, and surface hardening, they began to process the body and its structures by shot blasting, using lead shot, and using beam pneumatic hammers. This was done during the construction of the ship. It should have been carried out during the period of factory repairs, which, unfortunately, was not done, and therefore, after 10-15 years of operation, problems arose with the formation of cracks, especially in the second day, which led to fuel flooding, and as a result, a decrease in fuel reserve and autonomy by fuel reserves (fuel was simply not accepted into these tanks).
The lead ship of the BT-86 project was built for 4 years and was commissioned to the Navy by the Khabarovsk shipbuilding plant in 1963. Subsequently, the construction period of the project ships (from laying to commissioning to the fleet) took less than 2 years (18-20 months) . During the tests of the lead ship, its fundamental difference from all minesweepers previously built in the country, namely, its high degree of self-protection from mine explosions, was fully manifested. The level of the magnetic field of ships pr. 266 was reduced compared to ships pr. 254 and 264 by almost 40 times, electric - 10-15 times, acoustic in a wide frequency range - 3-4 times, hydrodynamic - by 20-30% . However, a change in the ratios of the main dimensions and contours of the ship led to some deterioration in the seaworthiness and habitability of the ship compared to its predecessors, ships pr. 254 and 264.
In 1963 - 1971 according to project 266, 41 units of ships and 4 units of ships in export modification were built at the Sredne-Nevsky and Khabarovsk shipyards (project 266E, chief designer N.P. Pegov). At the same time, 16 ships were built at the Khabarovsk shipbuilding plant, 39% of the entire series, (factory Nos. S-50 - S-65), which were included in the Pacific Fleet. It should be noted that the Khabarovsk shipbuilding plant together with the Vladivostok shipbuilding plant, starting from the 60s, fully implemented the program of military shipbuilding in terms of deliveries to the Pacific Fleet of ships of the 3rd - 4th rank (skr project 159 and its modifications, mrk project 1234 , project 201, 204, 1124, project 266, 266M, project 257 and its modifications, 1265, project 206, 206M, project 183, 205 and its modifications, 1241.1, 12411, project 205P border guards, 12412 , 12410 etc.). The Khabarovsk shipbuilding plant during this period worked more than intensively, handing over to the fleet almost 2 units annually. btsch pr. 266, 1-2 units. skr pr. 159, 1-2 units. MPK pr. 204. Subsequently, a number of Project 266 ships were transferred to the Navy of foreign states, in particular the Vietnamese Navy. In 1966, by order of the Civil Code of the Navy, a new classification of ship composition was introduced, according to which anti-mine ships with a displacement of more than 500 tons were classified as sea minesweepers, with a displacement of 150–500 tons as base minesweepers, and with a displacement of less than 150 tons as offshore ships. Accordingly, the ships of project 266 were transferred to the class of sea minesweepers. The composition of the Pacific Fleet included the following btsch (mtsch) of the project:

"MT - 86", serial number C - 50 (completion year 1963),

"MT - 53", serial number C - 51 (1964),

"MT - 58", serial number C - 52 (1965),

"MT - 27", serial number C - 53 (1966),

"MT - 80", serial number C - 54 (1966),

"MT - 82", serial number C - 55 (1966),

"MT - 238", serial number C - 56 (1967),

"MT - 242", serial number C - 57 (1967),

"MT - 193", serial number C - 58 (1968),

"MT - 200", serial number C - 59 (1968),

"MT - 208", serial number C - 60 (1969),

"MT - 221", serial number C - 61 (1970),

"MT - 257" (since 1981 MT "Vice-Admiral Sabaneev"), serial number C - 62 (1969),

"MT - 263", serial number C - 63 (1969),

MT "Midshipman Pavlov", serial number C - 64 (1971),

MT - "Mina", serial number C - 65 (1972).

After the construction, the ships were credited mainly to the 47 brkovr ( Russian island, b. Paris), several units in the composition of 114 brkovr (Petropavlovsk-Kamchatsky, Zavoyko b.). In those days, a somewhat paradoxical situation arose. The ships of the project, immediately after being built and accepted into the fleet, were put into reserve and mothballed, when it seemed that the place was completely new ships, with much lower levels of physical fields and more perfect types mine-sweeping weapons in comparison with the minesweepers of projects 254, 264, in constant readiness. So 9 units of the project (MT - 193, - 200, - 208, - 238, - 263, - 221, - 257, "Mina", "Midshipman Pavlov", this, in fact, is more than half of the entire series of the ship of the construction project Khabarovsk Shipyard) immediately after the construction were mothballed and included in the 71 dnkrez 47 brkovr and delivered to the b. Zhitkov (Russian Island). This was due to the fact that by that time the Pacific Fleet already had numerous minesweeping forces, consisting of minesweepers of project 254, 264, and the state of the fleet did not allow recruiting new crews. Later, already in the 70-80s, as project 254 minesweepers were excluded from the fleet, project 264 minesweepers were transferred to the class of patrol ships, project 266 minesweepers were withdrawn from the reserve, reactivated and transferred to 142 bottoms 114 brkovr, 13 dntsch 33 brkovr (Sakhalin Island, Korsakov village), 38 days 196 brkovr (Sovetskaya Gavan). At the same time, MT "Mina" and "MT - 221" were withdrawn from conservation and transferred to the Vietnamese Navy in 1979 and 1981, respectively. "MT - 257" ("Vice-Admiral Sabaneev" was also taken out of mothballing and included in the 186th day of the 7th brigade of the PrFlRS based in Abrek Bay, Strelok Bay. Subsequently, the ship was transferred to the 142th day of the 114th brigade of the KamFlRS ( Petropavlovsk-Kamchatsky, Zavoiko Bay) As the construction of project 266M minesweepers began and they were included in the 47 brkovr, part of the minesweepers of project 266 from this formation were withdrawn to the reserve and mothballed (MT - 53, - 86)
As the service progressed, the ships were transferred from one formation to another. So MT - 27 out of 47 brkovr in 1967 was transferred to the 142 dntsch 114 brkovr, MT - 193, - 238 out of 114 brkovr (Kamchatka) in 1978 were transferred to the 212 dntsch of the newly formed 137 brkovr (Sovgavan naval base, Kuril Islands, Simushir Island, Broughton Bay). As part of 142 dntsch 114 brkovr KamFlRS were MT - 27, - 58, - 80, - 82, - 208, as part of 13 dntsch 33 brkovr SakhFlRS MT - 200, "Michman Pavlov" (withdrawn from the reserve, reactivated and transferred to Sakhalin in 1977), consisting of 38 dntsch 196 brkovr MT-242 (withdrawn to the reserve, mothballed and transferred to the 82 brkrez in 1986), MT-263 (withdrawn from the reserve, reactivated and transferred to the 38 dntsch in 1986 .).

Project 266 vehicles of the Pacific Fleet during their service were involved in combat service in the areas of the Indian Ocean, the South China Sea and the Korea Strait. In 1974, as part of the Pacific Fleet minesweeping detachment, which carried out contact and non-contact minesweeping in the Gubay and Inner Channel Straits of the Suez Gulf (Red Sea), after the Arab-Israeli war, they performed the tasks of mtsch pr. 266 Pacific Fleet MT "Michman Pavlov", - 193 jointly with the project 254K MT - 66, - 104, the project 257DM BT - 103, - 284. The tasks were completed successfully.

MT-86 by order of the Civil Code of the Navy dated 06/20/1986 No. 0114 was excluded from the combat strength of the Pacific Fleet in 1987, MT-27, MT-53, MT-238 - by order of the Civil Code of the Navy dated 04.05.1989 No. 099 - in 1989, MT-58 - by order of the Civil Code of the Navy of 19.04.1990 No. 069 - in 1990, MT-80, MT-193 - by order of the Civil Code of the Navy of 06.24.1991 - in 1991, MT- 82, MT-200, MT "Midshipman Pavlov" -by order of the Civil Code of the Navy dated July 3, 1992 No.- in 1992, MT-242, MT-263, MT-257 ("Vice-Admiral Sabaneev") - by order of the Navy Civil Code dated 06/30/1993 No. 055 - in 1993,MT-208 - by order of the Civil Code of the Navy dated November 17, 1994 No. 086 - in 1994

All ships of the project were excluded from the combat strength of the fleet after the expiration of the directive life of the project (20 years). The ships served in the fleet from 21 years (MT "Midshipman Pavlov") to 26 years (MT-82, MT-242)

Scheme of minesweeper minesweeping.

They are the main component of the Navy of the armed forces of individual states of the world.

History [ | ]

In connection with the emergence of a new type of weapon in service with the fleets of the armed forces of many states - a sea mine, retaliatory measures were also required to successfully solve the eternal sword-shield problem, and it was successfully solved for the first time in the Russian Imperial Navy. Minesweepers were first used by the Russian Imperial Navy in Port Arthur in 1904.

The appearance of minesweepers-seekers of mines was caused by the improvement of mine fuses, which reduced the reliability of clearing. Therefore, a logical development of combat trawling was proposed: not to use trawls, but to search for and destroy mines with explosive charges. The main weapons here are search vehicles or swimmers-miners. The conditions for their use become more important, although the requirements for reducing the physical fields of the mine detector remain.

By 2000, the world's fleets had 60 minesweepers, 181 minesweepers, one squadron of minesweepers (22÷24 vehicles).

Aviation equipment can also be used as minesweepers. So during the Second World War, a number of bomber aircraft of the British Air Force were converted for these purposes. At the same time, a number of German Air Force (Luftwaffe) Junkers Yu 52 aircraft underwent similar modifications. To combat magnetic mines, they were equipped with large conductive rings and separate engines with generators to create a powerful magnetic field. The disadvantages of such systems, in addition to complicated piloting, was that with overly sensitive mine fuses, they could detonate right under the plane, which was forced to fly above the very surface of the water. In addition, mines could only be destroyed in this way at a very shallow depth. Currently, US Navy MH-53E helicopters are actively used as minesweepers.

Division [ | ]

In accordance with this, requirements for acoustic, electromagnetic stealth are imposed on the minesweeper. To meet them, the following measures are taken:

Constructive. The hull of the minesweeper is made of non-magnetic materials (wood, plastic), dimensions and draft are limited, demagnetizing devices are installed, damping and soundproofing of mechanisms are used, non-cavitating propellers.
Preventive. Periodically or before trawling, the physical fields of the ship (primarily acoustic and magnetic) are measured, and their reduction is carried out.
Tactical. The ship is used in modes that minimize induced fields: low speeds to reduce noise and dynamic pressure, movement along the Earth's magnetic lines, if possible, etc.

An excerpt characterizing the minesweeper

In the evening Prince Vasily arrived. He was met on the preshpekt (that was the name of the avenue) by coachmen and waiters, with a shout they drove his wagons and sledges to the wing along a road deliberately covered with snow.
Prince Vasily and Anatole were given separate rooms.
Anatole was sitting, taking off his doublet and propping himself on his hips, in front of the table, on the corner of which, smiling, he fixed his beautiful large eyes intently and absent-mindedly. He looked at his whole life as an uninterrupted entertainment, which someone for some reason undertook to arrange for him. So now he looked at his trip to the evil old man and to the rich ugly heiress. All this could come out, according to his assumption, very well and funny. And why not marry, if she is very rich? It never interferes, thought Anatole.
He shaved, perfumed himself with the thoroughness and panache that had become his habit, and with a good-natured victorious expression innate in him, carrying his beautiful head high, he entered the room to his father. Near Prince Vasily, his two valets bustled about, dressing him; he himself looked around him animatedly and nodded merrily to his son as he entered, as if he were saying: “So, that’s how I need you!”
- No, no jokes, father, is she very ugly? BUT? he asked, as if continuing a conversation that had been carried on more than once during the journey.
- Full. Nonsense! The main thing is to try to be respectful and prudent with the old prince.
“If he scolds, I will leave,” said Anatole. I can't stand these old people. BUT?
“Remember that everything depends on you.
At that time, the arrival of the minister with his son was not only known in the maid's room, but appearance both of them have already been described in detail. Princess Marya sat alone in her room and tried in vain to overcome her inner agitation.
“Why did they write, why did Lisa tell me about it? After all, this cannot be! she said to herself, looking in the mirror. - How do I get into the living room? Even if I liked him, I could not be myself with him now. Just the thought of her father's gaze horrified her.
The little princess and m lle Bourienne have already received all the necessary information from the maid Masha about what a ruddy, black-browed handsome minister's son was, and about how papa dragged their feet by force to the stairs, and he, like an eagle, walking up three steps, ran after him. Having received this information, the little princess with m lle Bourienne, still audible from the corridor with their animated voices, entered the princess's room.
- Ils sont arrives, Marieie, [They have arrived, Marie,] you know? - said the little princess, waddling her stomach and sinking heavily into an armchair.
She was no longer in the blouse in which she sat in the morning, and she was wearing one of her best dresses; her head was carefully removed, and on her face there was a revival, which, however, did not hide the drooping and dead outlines of her face. In the attire in which she usually went in society in St. Petersburg, it was even more noticeable how much she had grown ugly. On m lle Bourienne, too, there was already imperceptibly some improvement in the outfit, which made her pretty, fresh face even more attractive.
- Eh bien, et vous restez comme vous etes, chere princesse? she spoke. – On va venir annoncer, que ces messieurs sont au salon; il faudra descendre, et vous ne faites pas un petit brin de toilette! [Well, are you staying, what were you wearing, princess? Now they will come to say that they left. You will have to go downstairs, and at least you dressed up a little bit!]
The little princess got up from her chair, called the maid, and hurriedly and cheerfully began to invent an outfit for Princess Marya and put it into execution. Princess Marya felt insulted in her self-esteem by the fact that the arrival of the bridegroom promised to her excited her, and she was even more offended by the fact that both of her friends did not even imagine that it could be otherwise. To tell them how ashamed she was for herself and for them meant betraying her excitement; moreover, to refuse the dress that was offered to her would lead to lengthy jokes and insistence. She flushed, her beautiful eyes went out, her face became covered with spots, and with that ugly expression of the victim, which most often stops on her face, she surrendered to the power of m lle Bourienne and Lisa. Both women cared quite sincerely about making her beautiful. She was so bad that the thought of rivalry with her could not come to any of them; therefore, quite sincerely, with that naive and firm conviction of women that an outfit can make a face beautiful, they set about dressing her.

Enemy. We will talk about it in the article.

Some terminology

According to their principle of operation, minesweepers are divided into sea, basic, raid and river. Trawls are also divided into acoustic, contact and electromagnetic. Acoustic mines are designed to detonate acoustic mines, simulating the sound of a ship's passage. Contact trawls are the simplest in their design and consist of a chain with knives that cut the cables holding mines, after which the emerging charge is destroyed from the side of the minesweeper from machine guns or small-caliber artillery. Electromagnetic create an electric field that simulates a passing ship, and are used against magnetic mines. In the photo of minesweepers, you can also see the installation of depth charges, with which the minesweeper is able to perform the functions of a submarine hunter.

The birth of minesweepers

With the appearance in the arsenals of the fleets of the largest maritime powers of a new type of weapon - sea mines, the question arose of their search and neutralization. Mines have become the main means of defending naval bases and disrupting enemy sea lanes. The age-old question "shield-sword" was successfully resolved for the first time in the Russian Navy. Mine minesweepers received a baptism of fire in 1904 during the Russo-Japanese War. The combat experience of Russian minesweepers was thoroughly studied in other countries, resulting in a sharp increase in the number of minesweepers in active fleets in the interwar period.

The Second World War

Second World War gave a sharp impetus to all types of weapons, including warships. Mine minesweepers have become better protected and armed, they could perform other tasks:

to land troops;
shell the coast;
escort transport convoys;
evacuate troops.

The most advanced were the German minesweepers, whose crews received the “Mine Minesweeper” badge for their courage. After the end of the Second World War, the old minesweepers were engaged in mine clearance of the seas for a long time, giving up their combat post to new ships that used the best shipbuilding experience.

Modernity

The basic concept of the modern minesweeper was formulated in the UK in the 1960s. The ship, equipped with a powerful acoustic radar, searched for mines, and if they were found, released an uninhabited underwater vehicle, which was engaged in additional search and examination of the detected object. He destroys mines with an anti-mine apparatus: bottom - by imposing a subversive charge, contact - by biting the anchor cable. This one received in the world's fleets the name minesweeper-searcher (TSCHIM).

Since the 1970s and 1980s, almost all minesweepers in the world have been GOOD, either newly built or converted from old minesweepers. Trawls now perform a secondary function. With the wide spread of wide-band mines installed at the very bottom, with an impressive target detection range, a torpedo or missile warhead, a modern minesweeper needs to have a deep-water trawl to work close to the ground.

With the growth in the characteristics of commercial sonar stations, especially side-scan locators, it became possible to use them to search for and destroy mines, which dramatically increased the productivity of mine action forces. In ports and areas, near naval bases, advance inspection began to be carried out, as a result of which all objects resembling mines are entered into the catalog. This allows in wartime to immediately identify new objects, which, in the vast majority, will be mines. All this increases the effectiveness of mine action forces and allows you to guarantee a safe exit from ports and bases.

The development of anti-mine means, which began in the West in the 60s of the last century, led to an increase in the effectiveness of these forces. It is also noteworthy that the fight against mines is increasingly moving away from "highly specialized" actions, becoming a whole range of activities involving various forces and means.

During Operation Shock and Awe (the 2003 US and allied military invasion of Iraq), Iraqi minelayers, disguised as merchant ships, were captured by the Allied Special Operations Forces, more than 100 Iraqi mines were found and destroyed by divers and uninhabited underwater vehicles. As a result of these actions, the Allies did not suffer losses from Iraqi mines, which allowed the American ground forces to achieve complete success.

Modular anti-mine systems

IN Lately the rapid development of mine action forces resulted in the use of modular mine action systems (MPS). Warships and submarines equipped with these systems can now independently deal with mines without the need for minesweepers. The most interesting MPS is the RMS AN/WLD-1 uninhabited underwater vehicle. A semi-submerged, remotely controlled vehicle with a towed side-scan locator is capable of independently searching for mines at a great distance from the carrier ship for quite a long time. Now the US Navy has 47 such devices.

Marine TSCHK pr. 266

Marine TSCHK pr. 266 (MT-62). summer 1987

The sea minesweeper project 266 was designed by TsKB-363 (Western Design Bureau) under the direction of N.P. Pegova. TTZ for the development of the ship was issued in 1956. Preliminary design developed in 1957, and the technical design was approved in 1957.

The hull of the ship with an elongated forecastle and a double bottom throughout, was divided into nine compartments by watertight bulkheads. In order to reduce the magnetic field, it was made of low-magnetic steel * and had a demagnetizing device (both with general ship windings and with local ones, compensating the magnetic fields of the largest mechanisms and equipment elements) with an automatic current control system and an attachment for compensating eddy currents arising from when rolling. To reduce the acoustic field on the ship, soundproofing of noisy equipment, vibration damping coatings for the foundations of noisy mechanisms, soundproofing inserts in pipelines and shafting, as well as air shielding of low-noise propellers of large diameter, which had a relatively low rotation speed, were provided. The protection of ships from non-contact mines with electrical channels of the contactors was provided mainly by applying a dielectric coating on the surface of all parts in contact with sea water, as well as electrical insulation of bottom-outboard equipment, shafting, trawl mechanisms and trawl parts from the ship's hull. Compared with its predecessors - TShKK pr. 254 and pr. 264 - the magnetic field of the ship pr. 266 was reduced by more than 40 times, and the acoustic field was almost halved.

The main engines were located in echelon and controlled remotely. The search for anchor mines ahead along the course of the ship was provided by the GAS mine detection, and the detection of floating mines in the daytime and at night was provided by special electronic equipment. For ease of operation of the minesweeping equipment, it was equipped with hydraulic drives and had an automatic remote control. The trawls were serviced at different times or in combinations using two KBG-5 hydraulic beam cranes and a winch. They made it possible to trawl modern mines at depths from 25 to 150 m. Mines could be destroyed with cord charges (IU3-1 or ShZ-2 up to 2200 m long). The ships could take the second set of minesweeping equipment into overload. The minesweepers were adapted to operate in the conditions of the use of weapons of mass destruction and had a remotely controlled water protection system. In 1963–1971 in Khabarovsk (on the Khabarovsk Shipyard) and in Leningrad (on the Sredne-Nevsky Shipyard), 41 TSCs, pr. 266, were built for the Soviet fleet. the presence of a sighting column for fire control 30-mm AU AK-230. In addition, instead of KBG-5 crane-beams, they used crane-beams with electric drives (similar to those on the TShKK pr. 257D and pr. 257DM).

Until 1968, the ships entered service with the navigational PJ1C Neptune, which was replaced by the Don radar during operation or medium repairs. At the same time, all TSCHK pr. 266 were armed with two 25-mm guns 2M-ZM. Four ships were built for export according to Project 266E. Three of them were handed over to Egypt, and one to Vietnam. Project 266 ships began to be withdrawn from the fleet in the second half of the 80s, and at present (as of January 2007) none of them is in service. The main disadvantage of MTShch pr. 266 was the lack of means for searching and detecting bottom mines, as well as gusty pitching.
