torpedo boat is a small warship designed to destroy enemy warships and transport vessels with torpedoes. Widely used during World War II. By the beginning of the war, torpedo boats were poorly represented in the main fleets of Western naval powers, but with the beginning of the war, the construction of boats increased sharply. To the beginning of the Great Patriotic War The USSR had 269 torpedo boats. Over the course of the war, more than 30 torpedo boats were built, and 166 were received from the Allies.

The project of the first planing Soviet torpedo boat was developed in 1927 by a team of the Central Aerohydrodynamic Institute (TsAGI) under the leadership of A.N. Tupolev, later outstanding aircraft designer. The first experimental boat "ANT-3" ("Firstborn"), built in Moscow, was tested in Sevastopol. The boat had a displacement of 8.91 tons, the power of two gasoline engines was 1200 hp. s., speed 54 knots. Maximum length: 17.33 m, width 3.33 m, draft 0.9 m, Armament: 450 mm torpedo, 2 machine guns, 2 mines.

Comparing the Firstborn with one of the captured SMVs, we found out that the English boat was inferior to ours in both speed and maneuverability. On July 16, 1927, the experimental boat was included in the naval forces at the Black Sea. “Taking into account that this glider is an experimental design,” the acceptance certificate stated, “the commission believes that TsAGI completed the task assigned to it in full and the glider, regardless of some shortcomings of a naval nature, is subject to acceptance into the composition Naval Forces Red Army..." Work on improving torpedo boats at TsAGI continued, and in September 1928 the serial boat "ANT-4" ("Tupolev") was launched. Until 1932, our fleet received dozens of such boats, called "Sh- 4". In the Baltic, Black Sea and Far East Soon the first formations of torpedo boats appeared.

But "Sh-4" was still far from ideal. And in 1928, the fleet ordered another torpedo boat from TsAGI, named G-5 at the institute. It was a new ship at that time - in its stern there were trenches for powerful 533-mm torpedoes, and during sea trials it reached an unprecedented speed - 58 knots with full ammunition and 65.3 knots without load. Naval sailors considered it the best of the existing torpedo boats both in terms of armament and technical properties.

Torpedo boat "G-5" type

The lead boat of the new type "GANT-5" or "G5" (planing No. 5) was tested in December 1933. This boat with a metal hull was the best in the world, both in terms of armament and technical properties. It was recommended for mass production and by the beginning of the Great Patriotic War it became the main type of torpedo boats of the Soviet Navy. The serial "G-5", produced in 1935, had a displacement of 14.5 tons, the power of two gasoline engines was 1700 hp. s., speed 50 knots. Maximum length 19.1 m, width 3.4 m, draft 1.2 m. Armament: two 533 mm torpedoes, 2 machine guns, 4 mines. Produced for 10 years until 1944 various modifications. In total, more than 200 units were built.

"G-5" underwent baptism of fire in Spain and in the Great Patriotic War. On all seas they not only launched dashing torpedo attacks, but also launched minefields, hunted for enemy submarines, landed troops, guarded ships and convoys, trawled fairways, bombarding German bottom proximity mines with depth charges. Particularly difficult and sometimes unusual tasks were carried out by Black Sea boats during the Great Patriotic War. They had to escort... trains running along the Caucasian coast. They fired torpedoes at... the coastal fortifications of Novorossiysk. And finally, they fired missiles at fascist ships and... airfields.

However, the low seaworthiness of boats, especially the Sh-4 type, was no secret to anyone. With the slightest disturbance, they were filled with water, which easily splashed into the very low pilothouse, open at the top. The release of torpedoes was guaranteed in seas of no more than 1 point, and boats could simply remain at sea in seas of no more than 3 points. Due to their low seaworthiness, the Sh-4 and G-5 only in very rare cases achieved their designed range, which depended not so much on the fuel supply as on the weather.

This and a number of other shortcomings were largely due to the “aviation” origin of the boats. The designer based the project on a seaplane float. Instead of an upper deck, "Sh-4" and "G-5" had a steeply curved convex surface. While ensuring the strength of the body, it at the same time created a lot of inconvenience in maintenance. It was difficult to stay on it even when the boat was motionless. If it was in full swing, absolutely everything that fell on it was dumped.

This turned out to be a very big disadvantage during combat operations: the paratroopers had to be placed in the chutes of torpedo tubes - there was nowhere else to place them. Due to the lack of a flat deck, "Sh-4" and "G-5", despite relatively large reserves of buoyancy, were practically unable to transport serious cargo. On the eve of the Great Patriotic War, torpedo boats "D-3" and "SM-3" were developed - long-range torpedo boats. "D-3" had a wooden hull; according to its design, the torpedo boat "SM-3" with a steel hull was produced.

Torpedo boat "D-3"

Boats of the "D-3" type were produced in the USSR at two factories: in Leningrad and Sosnovka, Kirov region. By the beginning of the war, the Northern Fleet had only two boats of this type. In August 1941, five more boats were received from the plant in Leningrad. All of them were brought together into a separate detachment, which operated until 1943, until other D-3s began to enter the fleet, as well as Allied boats under Lend-Lease. The D-3 boats compared favorably with their predecessors, the G-5 torpedo boats, although in terms of combat capabilities they successfully complemented each other.

"D-3" had improved seaworthiness and could operate at a greater distance from the base than the boats of the "G-5" project. Torpedo boats of this type had a total displacement of 32.1 tons, a maximum length of 21.6 m (length between perpendiculars - 21.0 m), a maximum width of 3.9 on deck and 3.7 m along the bilge. The structural draft was 0. 8 m. The D-3 body was made of wood. The speed depended on the power of the engines used. GAM-34 750 l. With. allowed the boats to develop a speed of up to 32 knots, GAM-34VS 850 hp each. With. or GAM-34F 1050 l. With. - up to 37 knots, Packards with a power of 1200 hp. With. - 48 knots. The cruising range at full speed reached 320-350 miles, and at eight knots - 550 miles.

On experimental boats and serial "D-3" for the first time, side-drop torpedo tubes were installed. Their advantage was that they made it possible to fire a salvo from a stop, while boats of the G-5 type had to reach a speed of at least 18 knots - otherwise they would not have time to turn away from the fired torpedo.

The torpedoes were fired from the boat's bridge by igniting a galvanic ignition cartridge. The salvo was duplicated by the torpedoist using two ignition cartridges installed in the torpedo tube. "D-3" were armed with two 533-mm torpedoes of the 1939 model; the mass of each was 1800 kg (TNT charge - 320 kg), the range at a speed of 51 knots was 21 cables (about 4 thousand m). Small arms"D-3" consisted of two DShK machine guns of 12.7 mm caliber. True, during the war, the boats were equipped with a 20-mm Oerlikon automatic cannon, a coaxial 12.7 mm Colt-Browning machine gun, and some other types of machine guns. The boat's hull was 40 mm thick. In this case, the bottom was three-layer, and the side and deck were two-layer. The outer layer was larch, and the inner layer was pine. The sheathing was fastened with copper nails at the rate of five per square decimeter.

The D-3 hull was divided into five waterproof compartments by four bulkheads. In the first compartment there are 10-3 sp. there was a forepeak, in the second (3-7 ships) there was a four-seater cockpit. The galley and boiler enclosure are between the 7th and 9th frames, the radio cabin is between the 9th and 11th. Boats of the "D-3" type were equipped with improved navigation equipment compared to what was on the "G-5". The D-3 deck made it possible to take on board a landing group, and it was also possible to move on it during a campaign, which was impossible on the G-5. The living conditions of the crew, consisting of 8-10 people, made it possible for the boat to operate for a long time away from its main base. Heating of the vital compartments of the D-3 was also provided.

Komsomolets-class torpedo boat

"D-3" and "SM-3" were not the only torpedo boats developed in our country on the eve of the war. In those same years, a group of designers designed a small torpedo boat of the Komsomolets type, which, almost no different from the G-5 in displacement, had more advanced tube torpedo tubes and carried more powerful anti-aircraft and anti-submarine weapons. These boats were built using voluntary contributions. Soviet people, and therefore some of them, in addition to numbers, received names: “Tyumen Worker”, “Tyumen Komsomolets”, “Tyumen Pioneer”.

The Komsomolets type torpedo boat, manufactured in 1944, had a duralumin hull. The hull is divided by waterproof bulkheads into five compartments (space 20-25 cm). A hollow keel beam is laid along the entire length of the hull, performing the function of a keel. To reduce pitching, side keels are installed on the underwater part of the hull. Two aircraft engines are installed in the hull one after the other, while the length of the left propeller shaft was 12.2 m, and the right one - 10 m. The torpedo tubes, unlike previous types of boats, are tubular, not trough. The maximum seaworthiness of the torpedo bomber was 4 points. The total displacement is 23 tons, the total power of two gasoline engines is 2400 hp. s., speed 48 knots. Maximum length 18.7 m, width 3.4 m, average recess 1 m. Reservation: 7 mm bulletproof armor on the wheelhouse. Armament: two tube torpedo tubes, four 12.7 mm machine guns, six large depth charges, smoke equipment. Unlike other domestically built boats, the Komsomolets had an armored (7 mm thick sheet) deckhouse. The crew consisted of 7 people.

Your tall ones fighting qualities These torpedo bombers showed their greatest impact in the spring of 1945, when units of the Red Army were already completing the defeat of Nazi troops, advancing towards Berlin with heavy fighting. Soviet from the sea ground troops covered the ships of the Red Banner Baltic Fleet, and the entire burden of hostilities in the waters of the southern Baltic fell on the shoulders of the submarine crews, naval aviation and torpedo boats. Trying to somehow delay their inevitable end and preserve ports for the evacuation of retreating troops as long as possible, the Nazis made feverish attempts to sharply increase the number of search, strike and patrol groups of boats. These urgent measures to some extent aggravated the situation in the Baltic, and then four Komsomolets, which became part of the 3rd division of torpedo boats, were transferred to help the existing forces of the Red Banner Baltic Fleet.

These were last days The Great Patriotic War, the last victorious attacks of torpedo boats. The war will end, and the Komsomol members, covered in military glory, will forever be frozen on pedestals as a symbol of courage - as an example for descendants, as an edification for enemies.

Torpedo boats are fast, small-sized and fast vessels, whose main armament is self-propelled combat projectiles - torpedoes.

The ancestors of boats with torpedoes on board were the Russian mine ships “Chesma” and “Sinop”. Combat experience in military conflicts from 1878 to 1905 revealed a number of shortcomings. The desire to correct the disadvantages of boats led to two directions in the development of ships:

Dimensions and displacement have been increased. This was done in order to equip the boats with more powerful torpedoes, strengthen artillery, and increase seaworthiness.
The ships were small-sized, their design was lighter, so maneuverability and speed became an advantage and the main characteristics.

The first direction gave birth to such types of ships as. The second direction led to the appearance of the first torpedo boats.

Mine boat “Chamsa”

The first torpedo boats

One of the first torpedo boats was created by the British. They were called the “40-pounder” and “55-pounder” boats. They very successfully and actively participated in the hostilities in 1917.

The first models had a number of characteristics:

Small displacement of water - from 17 to 300 tons;
A small number of torpedoes on board - from 2 to 4;
High speed from 30 to 50 knots;
Light auxiliary weapon - machine gun from 12 to 40 - mm;
Unprotected design.

Torpedo boats of World War II

At the beginning of the war, boats of this class were not very popular among the participating countries. But during the war years their number increased 7-10 times. Soviet Union He also developed the construction of light ships, and by the beginning of hostilities, the fleet had approximately 270 torpedo-type boats in service.

Small ships were used in conjunction with aircraft and other equipment. Besides main task- attacks on ships, boats had the functions of scouts and lookouts, guarded convoys off the coast, laid mines, attacked submarines in coastal areas. Also used as vehicle for transporting ammunition, discharging troops and played the role of minesweepers for bottom mines.

Here are the main representatives of torpedo boats in the war:

England MTV boats, whose speed was 37 knots. Such boats were equipped with two single-tube devices for torpedoes, two machine guns and four deep mines.
German boats with a displacement of 115 thousand kilograms, a length of almost 35 meters and a speed of 40 knots. The armament of the German boat consisted of two devices for torpedo shells and two automatic anti-aircraft guns.
Italian MAS boats from the Balletto design organization reached speeds of up to 43-45 knots. They were equipped with two 450-mm torpedo launchers, one 13-caliber machine gun and six bombs.
The twenty-meter torpedo boat of the G-5 type, created in the USSR, had a number of characteristics: Displacement of water was about 17 thousand kilograms; Developed speed up to 50 knots; It was equipped with two torpedoes and two small-caliber machine guns.
Torpedo-class boats, model RT 103, in service with the US Navy, displaced about 50 tons of water, were 24 meters long and had a speed of 45 knots. Their armament consisted of four torpedo launchers, one 12.7 mm machine gun and 40 mm automatic anti-aircraft guns.
Japanese fifteen-meter torpedo boats of the Mitsubishi model had a small water displacement of up to fifteen tons. The T-14 type boat was equipped with a gasoline engine that reached a speed of 33 knots. It was armed with one 25-caliber cannon or machine gun, two torpedo shells and bomb throwers.

Mine boat MAS 1936

Torpedo-class ships had several advantages over other warships:

Small dimensions;
High speed abilities;
High maneuverability;
Small crew;
Little supply requirement;
The boats could quickly attack the enemy and also escape with lightning speed.

Schnellbots and their characteristics

Schnellbots are German torpedo boats from World War II. Its body was combined of wood and steel. This was dictated by the desire to increase speed, displacement and reduce financial and time resources for repairs. The conning tower was made of light alloy, had a conical shape and was protected by armored steel.

The boat had seven compartments:

– there was a cabin for 6 people;
– radio station, commander’s cabin and two fuel tanks;
– there are diesel engines;
– fuel tanks;
– dynamos;
– steering station, cockpit, ammunition depot;
– fuel tanks and steering gear.

Power point by 1944 it was improved to the diesel model MV-518. As a result, the speed increased to 43 knots.

The main weapons were torpedoes. As a rule, steam-gas G7a units were installed. The second effective weapon of the boats were mines. These were bottom shells of the types TMA, TMV, TMS, LMA, 1MV or anchor shells EMC, UMB, EMF, LMF.

The boat was equipped with additional artillery weapons, including:

One MGC/30 stern gun;
Two MG 34 portable machine gun mounts;
At the end of 1942, some boats were equipped with Bofors machine guns.

German boats were equipped with sophisticated technical equipment to detect the enemy. The FuMO-71 radar was a low-power antenna. The system made it possible to detect targets only at close distances: from 2 to 6 km. FuMO-72 radar with a rotating antenna, which was placed on the wheelhouse.

Metox station, which could detect enemy radar radiation. Since 1944, the boats have been equipped with the Naxos system.

Mini schnellbots

Mini boats of the LS type were designed for placement on cruisers and large ships. The boat had the following characteristics. The displacement is only 13 tons, and the length is 12.5 meters. The crew team consisted of seven people. The boat was equipped with two diesel engines Daimler Benz MB 507, which accelerated the boat to 25-30 knots. The boats were armed with two torpedo launchers and one 2 cm caliber cannon.

The KM type boats were 3 meters longer than the LS. The boat carried 18 tons of water. Two BMW gasoline engines were installed on board. The swimming apparatus had a speed of 30 knots. The boat's weapons included two devices for firing and storing torpedo shells or four mines and one machine gun.

Post-war ships

After the war, many countries abandoned the creation of torpedo boats. And they moved on to creating more modern missile ships. Construction continued to be carried out by Israel, Germany, China, the USSR and others. In the post-war period, boats changed their purpose and began to patrol coastal areas and fight enemy submarines.

The Soviet Union presented a Project 206 torpedo boat with a displacement of 268 tons and a length of 38.6 meters. Its speed was 42 knots. The armament consisted of four 533-mm torpedo tubes and two twin AK-230 launchers.

Some countries have begun producing mixed-type boats, using both missiles and torpedoes:

Israel produced the Dabur boat
China has developed a combined boat "Hegu"
Norway built the Hauk
In Germany it was "Albatross"
Sweden was armed with the Nordköping
Argentina had the Intrepid boat.

Soviet torpedo-class boats are warships used during the Second World War. These light, maneuverable vehicles were indispensable in combat conditions; they were used to land landing troops, transported weapons, carried out minesweeping and laying mines.

Torpedo boats model G-5, mass production which was carried out from 1933 to 1944. A total of 321 ships were produced. The displacement ranged from 15 to 20 tons. The length of such a boat was 19 meters. Two GAM-34B engines of 850 each were installed on board Horse power, allowing you to reach speeds of up to 58 knots. Crew – 6 people.

The weapons on board were a 7-62 mm DA machine gun and two 533 mm stern grooved torpedo tubes.

The armament consisted of:

Two twin machine guns
Two tube torpedo devices
Six M-1 bombs

Boats of the D3 model 1 and 2 series were planing vessels. The dimensions and mass of displaced water were practically the same. The length is 21.6 m for each series, the displacement is 31 and 32 tons, respectively.

The 1st series boat had three Gam-34BC gasoline engines and reached a speed of 32 knots. The crew included 9 people.

The Series 2 boat had a more powerful power plant. It consisted of three Packard gasoline engines with a capacity of 3,600 horsepower. The crew consisted of 11 people.

The armament was practically the same:

Two twelve-millimeter DShK machine guns;
Two devices for launching 533-mm torpedoes, model BS-7;
Eight BM-1 depth charges.

The D3 2 series was additionally equipped with an Oerlikon cannon.

The Komsomolets boat is an improved torpedo boat in all respects. Its body was made of duralumin. The boat consisted of five compartments. The length was 18.7 meters. The boat was equipped with two Packard gasoline engines. The ship reached a speed of up to 48 knots.

Torpedo boat D-3: warrior of the North

Soviet torpedo boats of the D-3 type were produced in parallel with the G-5 boats, but turned out to be capable of performing many more tasks than their competitors. Meet the new boat in the USSR research line!

The project of the small torpedo boat D-3 was developed in Leningrad in 1939-1940. In August 1940, the prototype was accepted for testing by sailors of the Black Sea Fleet and entered service in the same year. Despite the fact that the D-3 differed little from the G-5 boat in terms of armament and dimensions, it showed excellent potential in the range of tasks performed. The D-3 favorably differed from its competitor in its higher seaworthiness and cruising range, the reliability of the units and design as a whole, more advanced navigation equipment and the presence of a habitable deck, which made it possible to use the D-3 as a light and fast landing transport.

The combat effectiveness of the D-3 boats is perfectly illustrated by the actions of these vessels during the brilliantly conducted landing operation Soviet Northern Fleet in Liinakhamari and the fighting that preceded the decisive blow. The D-3 boats not only effectively fought the Nazi convoys, but also played a decisive role in the capture artillery batteries Petsamo fjord, delivering paratroopers to enemy fortifications under heavy fire from the shore. Experience combat use D-3 boats showed their high survivability - despite the fact that the hull structure was made of wood different breeds, torpedo boats were capable of surviving hundreds of holes and leading the crew out from under enemy fire.

IN War Thunder The D-3 torpedo boat is located at the lower ranks of the USSR fleet research line. This is a small vessel with a length of just over 22 meters and a displacement of 36 tons. The power plant consists of three gasoline engines of the GAM-34 series, which give the boat a maximum speed of 32 knots (60 km/h).

The boat's armament consists of two 53-38 torpedoes of 533mm caliber - the same as on the G-5 boats, but the torpedoes are launched by dropping them overboard along the course of the boat. The D-3 has two heavy machine guns DShK, there was also a place to place depth charges. The boat's crew is 9 people.

The D-3 torpedo boat will be one of the first boats available for testing to participants in the closed beta test of War Thunder naval battles. Hurry up to be among the first testers of the War Thunder fleet. See you in battle!

Description

Ride quality

The total displacement is just over 32 tons. Maximum dimensions: 21.6 × 3.9 × 0.8 m. Speed depended on the engines: engines of the GAM-34 family gave a speed from 32 to 37 knots, American engines Packard 4M-2500, supplied under Lend-Lease - up to 48 knots. Cruising range at maximum speed is up to 320-350 miles, at a speed of 8 knots - 550 miles. The boat could be used in winds of no more than force 6.

Armament

The boat was equipped with two 12.7 mm DShK machine guns. Some boats were armed with machine guns from Colt, Browning and others, and some were equipped with an automatic 20-mm Oerlikon cannon. The main torpedo armament was BS-7 torpedo tubes, from which two 533 mm torpedoes of the 1939 model were launched (each weighing 1800 kg with a TNT charge of 320 kg, speed up to 51 knots, range 21 cables). The shot was fired from the bridge of the boat when the galvanic ignition cartridge was ignited.

Protection

The boat hull is made of wood, up to 40 mm thick. For protection, the bottom is made of three layers, and the side and deck are made of two layers (the outer one is made of larch, the inner one is made of pine). The sheathing was fastened with copper nails in a ratio of 5 nails per square. decimeter. With minor damage, the pine swelled and closed the holes and holes. Ordinary bricks were used as ballast.

Premises

The hull was divided into five waterproof compartments: the first forepeak, the second a four-berth cockpit, there was also a galley, a boiler enclosure and a radio cabin (heating was provided for them). Navigation equipment was better than on G-5 type boats. You can also take a landing group on board. A crew of 8-10 people allowed the boat to operate for a long time away from the base.

Construction

The boats were built at factories in Leningrad and Sosnovka (Kirov region). Before the war, the Northern Fleet had only two boats, but in August 1941, Leningrad workers managed to build and commission five more. These seven boats were combined into a separate detachment, which operated until 1943. In 1943, serial production of boats resumed.

Service

The survivability of the boats was high. In the landing operation in Liinakhamari, in which two groups of Northern Fleet boats took part under the command of Lieutenant Commander A. O. Shabalin and captain 2nd rank

Designed under the guidance of designer L.L. Ermasha in 1939, as long-range boats, were intended to conduct torpedo attacks not only in cramped coastal areas but also in the near sea zone.

The boat's hull was made of two layers of wood, the outer layer was made of larch, and the inner layer was made of pine, with a total thickness of 40 mm. The bottom of the boat was three-layered. The sheathing boards were fastened with copper nails at the rate of five pieces per square decimeter. The deck also consisted of two layers of wood and was straight along its entire length, which allowed free movement along it during a campaign and made it possible to comfortably accommodate a platoon of paratroopers. In the middle of the hull there was a closed wheelhouse with observation glasses. Control devices were installed inside the wheelhouse: a steering wheel, an engine telegraph, three tachometers (one per engine), drives for gas control throttles, a magnetic compass, a tablet with maps, and an automatic firing box for launching torpedoes.
Unsinkability was ensured by dividing the hull with waterproof bulkheads into 5 compartments:

Forepeak;
Kubrick, radio room and galley, commander's cabin, electrical department;
Motor;
Skipper's Pantry;
Fuel tank, tiller compartment.

Ordinary stove bricks were used as ballast on the boat. Were improved conditions crew habitat, heating of vital compartments was provided, which made it possible for the boat to operate for a long time away from its main base.

The power plant is mechanical, three-shaft, with three domestic GAM-34 gasoline aviation engines of 750 hp each. each with reverse gears, with maximum speed rotation up to 1850 rpm. The boat's full speed could be used for no more than an hour. The maximum engine speed during combat training operations was allowed no more than 1600 rpm. A working motor started in 6-8 seconds. after switching on. The maximum permissible speed in reverse is 1200. The engine operating time in reverse is 3 minutes. B-70 gasoline was used as fuel. After 150 hours of operation, the new engine required a complete overhaul.

The armament of the boats consisted of:

Of 2 large-caliber 12.7 mm DShK machine guns with a barrel length of 84.25 caliber, which were located one on the roof of the cabin and one on the tank. The fire mode is automatic only, built on the gas principle, and has a muzzle brake. The rate of fire of the installation was 600 rounds/min. at initial speed cartridge 850 m/s, firing range up to 3.5 km, ceiling up to 2.4 km. The machine guns are powered by a belt, with 50 rounds per belt. Firing is carried out in bursts of up to 125 rounds, after which cooling is required. The machine gun crew included 2 people. For ease of aiming, a shoulder pad with adjustable shoulder pads is provided. The machine guns had a manual control system with optical sight. Installation weight - no data.

The boats were equipped with a KI-6 magnetic compass and a Shtil-K radio station.

The Shtil-K radio station could operate in telephone mode, had a power of 10-20 W and operated in the range of 75-300 meters with a range of 20 miles.

Construction was carried out at the NKVD plant No. 5 in Leningrad.

Torpedo boats type D-3 (Project 19) series II

- differed from the previous series by the installed Lend-Lease American Packard gasoline engines and reinforced artillery weapons.

The power plant is mechanical, three-shaft with three Packard gasoline aircraft engines of 1200 hp each. every. The full speed of the boat reached 45 knots. A working motor started in 5-6 seconds. after switching on.

The armament of the boats consisted of:

Of 2 BS-7 torpedo tubes for two 533 mm torpedoes. Torpedo tubes (TA) are grips for torpedoes (mines), similar to those used in military aviation grips for hanging ammunition under the fuselage of airplanes and helicopters. For onboard dropping of torpedoes, a galvanic ignition device was used, which consisted of two igniter cartridges installed in the torpedo tube, an electrical wire and a galvanic element (battery) when the circuit was closed, the current was supplied to the igniter.
