Submarines dictate the rules in naval war and force everyone to meekly follow the established order. Those stubborn people who dare to ignore the rules of the game will face a quick and painful death in the cold water, among floating debris and oil stains. Boats, regardless of flag, remain the most dangerous combat vehicles, capable of crushing any enemy. I present to your attention short story about the seven most successful submarine projects of the war years.
Boats type T (Triton-class), UK
Number of submarines built - 53. Surface displacement - 1290 tons; underwater - 1560 tons. Crew - 59…61 people. Working immersion depth - 90 m (riveted hull), 106 m (welded hull). Full surface speed - 15.5 knots; in underwater - 9 knots. A fuel reserve of 131 tons provided a surface cruising range of 8,000 miles. Armament: - 11 torpedo tubes of 533 mm caliber (on boats of subseries II and III), ammunition - 17 torpedoes; - 1 x 102 mm universal gun, 1 x 20 mm anti-aircraft "Oerlikon".
HMS Traveler British submarine Terminator, capable of “knocking the crap out” of any enemy with the help of a bow 8-torpedo salvo. Boats of the "T" type had no equal in destructive power among all submarines of the WWII period - this explains their ferocious appearance with a bizarre bow superstructure, where additional torpedo tubes were located. The notorious British conservatism is a thing of the past - the British were among the first to equip their boats with ASDIC sonars. Alas, despite its powerful weapons and modern means detection, boats open sea type "T" did not become the most effective among the British submarines of World War II. Nevertheless, they went through an exciting battle path and achieved a number of remarkable victories. “Tritons” were actively used in the Atlantic, in the Mediterranean Sea, destroyed Japanese communications in the Pacific Ocean, and were spotted several times in the frozen waters of the Arctic. In August 1941, the submarines "Tygris" and "Trident" arrived in Murmansk. British submariners demonstrated a master class to their Soviet colleagues: in two trips, 4 enemy ships were sunk, incl. "Bahia Laura" and "Donau II" with thousands of soldiers of the 6th Mountain Division. Thus, the sailors prevented the third German attack on Murmansk. Other famous T-boat trophies include the German light cruiser Karlsruhe and the Japanese heavy cruiser Ashigara. The samurai were “lucky” to get acquainted with a full 8-torpedo salvo of the Trenchent submarine - having received 4 torpedoes on board (+ another one from the stern tube), the cruiser quickly capsized and sank. After the war, the powerful and sophisticated Tritons remained in service with the Royal Navy for another quarter of a century. It is noteworthy that three boats of this type were acquired by Israel in the late 1960s - one of them, INS Dakar (formerly HMS Totem) was lost in 1968 in the Mediterranean Sea under unclear circumstances. Number of submarines built - 11. Surface displacement - 1500 tons; underwater - 2100 tons. Crew - 62…65 people. Working diving depth - 80 m, maximum - 100 m. Full surface speed - 22.5 knots; in underwater - 10 knots. Cruising range on the surface 16,500 miles (9 knots) Cruising range underwater - 175 miles (3 knots) Armament: - 10 torpedo tubes of 533 mm caliber, ammunition - 24 torpedoes; - 2 x 100 mm universal guns, 2 x 45 mm anti-aircraft semi-automatic guns; - up to 20 minutes of barrage. 
...December 3, 1941, German hunters UJ-1708, UJ-1416 and UJ-1403 bombed Soviet boat, which attempted to attack the convoy at Bustad Sund. - Hans, can you hear this creature? - Nain. After a series of explosions, the Russians lay low - I detected three impacts on the ground... - Can you determine where they are now? - Donnerwetter! They are blown away. They probably decided to surface and surrender. The German sailors were wrong. From depths of the sea A MONSTER rose to the surface - the cruising submarine K-3 series XIV, unleashing a barrage of artillery fire on the enemy. With the fifth salvo, Soviet sailors managed to sink U-1708. The second hunter, having received two direct hits, began to smoke and turned to the side - his 20 mm anti-aircraft guns could not compete with the “hundreds” of the secular submarine cruiser. Scattering the Germans like puppies, K-3 quickly disappeared over the horizon at 20 knots. The Soviet Katyusha was a phenomenal boat for its time. Welded hull, powerful artillery and mine-torpedo weapons, powerful diesel engines (2 x 4200 hp!), high surface speed of 22-23 knots. Huge autonomy in terms of fuel reserves. Remote control ballast tank valves. Radio station capable of transmitting signals from the Baltic to Far East. An exceptional level of comfort: shower cabins, refrigerated tanks, two seawater desalinators, an electric galley... Two boats (K-3 and K-22) were equipped with Lend-Lease ASDIC sonars. 
But, oddly enough, neither the high characteristics nor the most powerful weapons made the Katyusha an effective weapon - in addition to dark history with the K-21 attack on the Tirpitz, during the war years the XIV series boats accounted for only 5 successful torpedo attacks and 27 thousand brigades. reg. tons of sunk tonnage. Most of victories were won with the help of mines. Moreover, its own losses amounted to five cruising boats. 
K-21, Severomorsk, our days The reasons for the failures lie in the tactics of using Katyushas - the powerful submarine cruisers, created for the vastness of the Pacific Ocean, had to “tread water” in the shallow Baltic “puddle”. When operating at depths of 30-40 meters, a huge 97-meter boat could hit the ground with its bow while its stern was still sticking out on the surface. It was a little easier for the North Sea sailors - as practice has shown, the effectiveness combat use“Katyusha” was complicated by poor training of personnel and lack of initiative by the command. It's a pity. These boats were designed for more. Series VI and VI-bis - 50 built. Series XII - 46 built. Series XV - 57 built (4 took part in hostilities). Performance characteristics of boats of type M series XII: Surface displacement - 206 tons; underwater - 258 tons. Autonomy - 10 days. Working diving depth - 50 m, maximum - 60 m. Full surface speed - 14 knots; in underwater - 8 knots. Cruising range on the surface is 3,380 miles (8.6 knots). Submerged cruising range is 108 miles (3 knots). Armament: - 2 torpedo tubes of 533 mm caliber, ammunition - 2 torpedoes; - 1 x 45 mm anti-aircraft semi-automatic. Baby! Mini-submarine project to quickly strengthen the Pacific Fleet - main feature M-type boats now have the ability to be transported by rail in a fully assembled form. In the pursuit of compactness, many had to be sacrificed - service on the Malyutka turned into a grueling and dangerous undertaking. Heavy living conditions, a strong “bumpiness” - the waves mercilessly threw the 200-ton “float”, risking breaking it into pieces. Shallow immersion depth and weak weapon. But the main concern of the sailors was the reliability of the submarine - one shaft, one diesel engine, one electric motor - the tiny “Malyutka” left no chance for the careless crew, the slightest malfunction on board threatened death for the submarine. The little ones quickly evolved - the performance characteristics of each new series were several times different from the previous project: the contours were improved, the electrical equipment and detection equipment were updated, the dive time was reduced, and the autonomy increased. The “babies” of the XV series no longer resembled their predecessors of the VI and XII series: one-and-a-half-hull design - the ballast tanks were moved outside the durable hull; The power plant received a standard two-shaft layout with two diesel engines and underwater electric motors. The number of torpedo tubes increased to four. Alas, Series XV appeared too late - the “Little Ones” of Series VI and XII bore the brunt of the war. 
Despite their modest size and only 2 torpedoes on board, the tiny fish were simply distinguished by their terrifying “gluttony”: in just the years of World War II, Soviet M-type submarines sank 61 enemy ships with a total tonnage of 135.5 thousand gross tons, destroyed 10 warships, and also damaged 8 transports. Babes originally intended only for action in coastal zone, learned to fight effectively in open sea areas. They, along with larger boats, cut enemy communications, patrolled at the exits of enemy bases and fjords, deftly overcame anti-submarine barriers and blew up transports right at the piers inside protected enemy harbors. It’s simply amazing how the Red Navy were able to fight on these flimsy ships! But they fought. And we won! Number of submarines built - 41. Surface displacement - 840 tons; underwater - 1070 tons. Crew - 36…46 people. Working diving depth - 80 m, maximum - 100 m. Full surface speed - 19.5 knots; submerged - 8.8 knots. Surface cruising range 8,000 miles (10 knots). Submerged cruising range 148 miles (3 knots). “Six torpedo tubes and the same number of spare torpedoes on racks convenient for reloading. Two cannons with large ammunition, machine guns, explosive equipment... In a word, there is something to fight with. And 20 knots surface speed! It allows you to overtake almost any convoy and attack it again. The technology is good...” - opinion of the S-56 commander, Hero of the Soviet Union G.I. Shchedrin 
The S-33 "Eski" was distinguished by a rational layout and balanced design, powerful weapons, excellent performance and seaworthiness. Initially a German project from the Deshimag company, modified to meet Soviet requirements. But don’t rush to clap your hands and remember the Mistral. After the start of serial construction of the IX series in Soviet shipyards, the German project was revised with the goal of a complete transition to Soviet equipment: 1D diesel engines, weapons, radio stations, a noise direction finder, a gyrocompass... - there were none in the boats designated “series IX-bis”. foreign made bolt! The problems with the combat use of "Medium" type boats, in general, were similar to the K-type cruising boats - locked in mine-infested shallow water, they were never able to realize their high combat qualities. Things were much better in the Northern Fleet - during the war, the S-56 boat under the command of G.I. Shchedrina crossed the Tikhy and atlantic oceans, moving from Vladivostok to Polyarny, subsequently becoming the most productive boat of the USSR Navy. No less fantastic story connected with the “bomb catcher” S-101 - during the war years, the Germans and Allies dropped over 1000 depth charges on the boat, but each time the S-101 returned safely to Polyarny. Finally, it was on the S-13 that Alexander Marinesko achieved his famous victories. 
Torpedo compartment S-56 “Cruel alterations in which the ship found itself, bombings and explosions, depths far exceeding the official limit. The boat protected us from everything…” - from the memoirs of G.I. Shchedrin Gato type boats, USA
Number of submarines built - 77. Surface displacement - 1525 tons; underwater - 2420 tons. Crew - 60 people. Working diving depth - 90 m. Full surface speed - 21 knots; submerged - 9 knots. Cruising range on the surface is 11,000 miles (10 knots). Submerged cruising range 96 miles (2 knots). Armament: - 10 torpedo tubes of 533 mm caliber, ammunition - 24 torpedoes; - 1 x 76 mm universal gun, 1 x 40 mm Bofors anti-aircraft gun, 1 x 20 mm Oerlikon; - one of the boats - USS Barb was equipped reactive system volley fire for shelling the coast.
Ocean-going submarine cruisers of the Getou class appeared at the height of the war in the Pacific Ocean and became one of the most effective tools of the US Navy. They tightly blocked all strategic straits and approaches to the atolls, cut all supply lines, leaving Japanese garrisons without reinforcements, and Japanese industry without raw materials and oil. In fights with "Getow" Imperial Navy lost two heavy aircraft carriers, lost four cruisers and a damn dozen destroyers. High speed, killer torpedo weapon, the most modern radio equipment for detecting the enemy - radar, direction finder, sonar. Cruising range providing combat patrol off the coast of Japan while operating from a base in Hawaii. Increased comfort on board. But the main thing is the excellent training of the crews and the weakness of Japanese anti-submarine weapons. As a result, the "Getow" mercilessly destroyed everything - it was they who brought victory in the Pacific Ocean from the blue depths of the sea. 
...One of the main achievements of the Getow boats, which changed the whole world, is considered to be the event of September 2, 1944. On that day, the Finback submarine detected a distress signal from a falling plane and, after many hours of searching, found a frightened and already desperate pilot in the ocean . The one who was saved was one George Herbert Bush. 
The cabin of the submarine "Flasher", memorial in Groton. The list of Flasher trophies sounds like a naval joke: 9 tankers, 10 transports, 2 patrol ships with a total tonnage of 100,231 GRT! And for a snack, the boat grabbed a Japanese cruiser and a destroyer. Lucky damn thing! Electric robots type XXI, Germany
By April 1945, the Germans managed to launch 118 submarines of the XXI series. However, only two of them were able to achieve operational readiness and go to sea in last days war. Surface displacement - 1620 tons; underwater - 1820 tons. Crew - 57 people. Working depth of immersion is 135 m, maximum depth is 200+ meters. Full speed in the surface position is 15.6 knots, in the submerged position - 17 knots. Cruising range on the surface is 15,500 miles (10 knots). Submerged cruising range 340 miles (5 knots). Armament: - 6 torpedo tubes of 533 mm caliber, ammunition - 17 torpedoes; - 2 Flak anti-aircraft guns of 20 mm caliber.
U-2540 "Wilhelm Bauer" permanently moored in Bremerhaven, present day Our allies were very lucky that all the forces of Germany were sent to the Eastern Front - the Krauts did not have enough resources to release a flock of fantastic "Electric Boats" into the sea. If they appeared a year earlier, that would be it! Another turning point in the Battle of the Atlantic. The Germans were the first to guess: everything that shipbuilders in other countries are proud of - large ammunition, powerful artillery, high surface speed of 20+ knots - is of little importance. The key parameters that determine the combat effectiveness of a submarine are its speed and cruising range when submerged. Unlike its peers, “Electrobot” was focused on being constantly under water: a maximally streamlined body without heavy artillery, fences and platforms - all for the sake of minimizing underwater resistance. Snorkel, six groups of batteries (3 times more than on conventional boats!), powerful full-speed electric motors, quiet and economical “sneak” electric motors. 
The stern of U-2511, sunk at a depth of 68 meters. The Germans calculated everything - the entire “Electrobot” campaign moved at periscope depth under the RDP, remaining difficult to detect for enemy anti-submarine weapons. On great depth its advantage became even more shocking: 2-3 times greater power reserve, with twice higher speed than any of the wartime submarines! High stealth and impressive underwater skills, homing torpedoes, a complex of the most advanced detection means... “Electrobots” opened a new milestone in the history of the submarine fleet, defining the vector of development of submarines in post-war years. The Allies were not prepared to face such a threat - as post-war tests showed, the “Electrobots” were several times superior in mutual hydroacoustic detection range to the American and British destroyers guarding the convoys. Type VII boats, Germany
(the given performance characteristics correspond to boats of the VIIC subseries) The number of submarines built is 703. Surface displacement is 769 tons; underwater - 871 tons. Crew - 45 people. Working diving depth - 100 m, maximum - 220 meters Full speed in the surface position - 17.7 knots; submerged - 7.6 knots. Cruising range on the surface is 8,500 miles (10 knots). Submerged cruising range 80 miles (4 knots). Armament: - 5 torpedo tubes of 533 mm caliber, ammunition - 14 torpedoes; - 1 x 88 mm universal gun (until 1942), eight options for add-ons with 20 and 37 mm anti-aircraft installations.
The most effective warships of all who have ever plowed the world's oceans. A relatively simple, cheap, mass-produced, but at the same time well-armed and deadly weapon for total underwater terror. 703 submarines. 10 MILLION tons of sunk tonnage! Battleships, cruisers, aircraft carriers, destroyers, corvettes and enemy submarines, oil tankers, transports with aircraft, tanks, cars, rubber, ore, machine tools, ammunition, uniforms and food... The damage from the actions of German submariners exceeded all reasonable limits - if only Without the inexhaustible industrial potential of the United States, capable of compensating for any losses of the allies, German U-bots had every chance to “strangle” Great Britain and change the course of world history. 
U-995. Graceful underwater killer
The successes of the Sevens are often associated with the “prosperous times” of 1939-41. - allegedly, when the Allies appeared the convoy system and Asdik sonars, the successes of the German submariners ended. A completely populist statement based on a misinterpretation of “prosperous times.” The situation was simple: at the beginning of the war, when for every German boat there was one Allied anti-submarine ship, the “sevens” felt like invulnerable masters of the Atlantic. It was then that the legendary aces appeared, sinking 40 enemy ships. The Germans already held victory in their hands when the Allies suddenly deployed 10 anti-submarine ships and 10 aircraft for each active Kriegsmarine boat! Beginning in the spring of 1943, the Yankees and British began to methodically overwhelm the Kriegsmarine with anti-submarine equipment and soon achieved an excellent loss ratio of 1:1. They fought like that until the end of the war. The Germans ran out of ships faster than their opponents. The whole history of the German “sevens” is a formidable warning from the past: what threat does the submarine pose and how high are the costs of creating effective system countering the underwater threat.
A funny American poster of those years. "Hit the weak points! Come serve in the submarine fleet - we account for 77% of the sunk tonnage!" Comments, as they say, are unnecessary I bring to your attention a short story about the seven most successful submarine projects of the war years.
T-type boats (Triton-class), Great Britain Number of submarines built - 53. Surface displacement - 1290 tons; underwater - 1560 tons. Crew - 59…61 people. Working immersion depth - 90 m (riveted hull), 106 m (welded hull). Full surface speed - 15.5 knots; in underwater - 9 knots.

It is noteworthy that three boats of this type were acquired by Israel in the late 1960s - one of them, INS Dakar (formerly HMS Totem) was lost in 1968 in the Mediterranean Sea under unclear circumstances.
Boats of the "Cruising" type, series XIV, Soviet Union Number of submarines built - 11. Surface displacement - 1500 tons; underwater - 2100 tons. Crew - 62…65 people. Working diving depth - 80 m, maximum - 100 m. Full surface speed - 22.5 knots; in underwater - 10 knots.

Welded hull, powerful artillery and mine-torpedo weapons, powerful diesel engines (2 x 4200 hp!), high surface speed of 22-23 knots. Huge autonomy in terms of fuel reserves.

It's a pity. These boats were designed for more.
“Malyutki”, Soviet Union Series VI and VI-bis - 50 built. Series XII - 46 built. Series XV - 57 built (4 took part in hostilities). Performance characteristics of boats of type M series XII: Surface displacement - 206 tons; underwater - 258 tons. Autonomy - 10 days. Working diving depth - 50 m, maximum - 60 m.

Armament: - 2 torpedo tubes of 533 mm caliber, ammunition - 2 torpedoes; - 1 x 45 mm anti-aircraft semi-automatic.
Baby! The project of mini-submarines for the rapid strengthening of the Pacific Fleet - the main feature of the M-type boats was the ability to be transported by rail in a fully assembled form. In the pursuit of compactness, many had to be sacrificed - service on the Malyutka turned into a grueling and dangerous undertaking. Difficult living conditions, strong roughness - the waves mercilessly tossed the 200-ton “float”, risking breaking it into pieces. Shallow diving depth and weak weapons.

Shchedrina made the transition through the Pacific and Atlantic oceans, moving from Vladivostok to Polyarny, subsequently becoming the most productive boat of the USSR Navy. An equally fantastic story is connected with the S-101 “bomb catcher” - during the war years, the Germans and Allies dropped over 1000 depth charges on the boat, but each time the S-101 returned safely to Polyarny. Finally, it was on the S-13 that Alexander Marinesko achieved his famous victories.
Gato class boats, USA Number of submarines built - 77. Surface displacement - 1525 tons; underwater - 2420 tons. Crew - 60 people. Working diving depth - 90 m.

Unlike its peers, “Electrobot” was focused on being constantly under water: a maximally streamlined body without heavy artillery, fences and platforms - all for the sake of minimizing underwater resistance. Snorkel, six groups of batteries (3 times more than on conventional boats!), powerful electric. Full speed engines, quiet and economical electric. "sneak" engines.
The stern of U-2511, sunk at a depth of 68 meters. The Germans calculated everything - the entire “Electrobot” campaign moved at periscope depth under the RDP, remaining difficult to detect for enemy anti-submarine weapons. At great depths, its advantage became even more shocking: 2-3 times greater range, at twice the speed of any wartime submarine! High stealth and impressive underwater skills, homing torpedoes, a set of the most advanced detection means... “Electrobots” opened a new milestone in the history of the submarine fleet, defining the vector of development of submarines in the post-war years. The Allies were not prepared to face such a threat - as post-war tests showed, the “Electrobots” were several times superior in mutual hydroacoustic detection range to the American and British destroyers guarding the convoys.

The most effective warships ever to roam the world's oceans. A relatively simple, cheap, mass-produced, but at the same time well-armed and deadly weapon for total underwater terror. 703 submarines. 10 MILLION tons of sunk tonnage! Battleships, cruisers, aircraft carriers, destroyers, corvettes and enemy submarines, oil tankers, transports with aircraft, tanks, cars, rubber, ore, machine tools, ammunition, uniforms and food... The damage from the actions of German submariners exceeded all reasonable limits - if only Without the inexhaustible industrial potential of the United States, capable of compensating for any losses of the allies, German U-bots had every chance to “strangle” Great Britain and change the course of world history.
U-995. Graceful underwater killer The successes of the “sevens” are often associated with the “prosperous times” of 1939-41. - allegedly, when the Allies appeared the convoy system and Asdik sonars, the successes of the German submariners ended. A completely populist statement based on a misinterpretation of “prosperous times.” The situation was simple: at the beginning of the war, when for every German boat there was one Allied anti-submarine ship, the “sevens” felt like invulnerable masters of the Atlantic. It was then that the legendary aces appeared, sinking 40 enemy ships. The Germans already held victory in their hands when the Allies suddenly deployed 10 anti-submarine ships and 10 aircraft for each active Kriegsmarine boat! Beginning in the spring of 1943, the Yankees and British began to methodically overwhelm the Kriegsmarine with anti-submarine equipment and soon achieved an excellent loss ratio of 1:1. They fought like that until the end of the war. The Germans ran out of ships faster than their opponents. The whole history of the German “seven” is a formidable warning from the past: what threat does a submarine pose and how high are the costs of creating an effective system to counter the underwater threat.
A funny American poster of those years. "Hit the weak points! Come serve in the submarine fleet - we account for 77% of the sunk tonnage!" Comments, as they say, are unnecessary.
In 1936, the submarine S-56 was laid down - the most productive Soviet submarine during the Great Patriotic War. Patriotic War. This boat is also famous for being the first Soviet submarine to circumnavigate the world.
“Six torpedo tubes and the same number of spare torpedoes on racks convenient for reloading. Two cannons with large ammunition, machine guns, explosive equipment... In a word, there is something to fight with. And 20 knots surface speed! It allows you to overtake almost any convoy and attack it again. The technology is good...” - this is how Captain Georgy Ivanovich Shchedrin, Hero of the Soviet Union, spoke about his boat S-56.
The "C" in the name stands for "Medium". This is a Soviet diesel-electric torpedo submarine - a converted German project by DeSchiMAG ("German Ship and Engineering Company"), which Soviet designers thoroughly redesigned for the Soviet production base. They changed diesel engines, weapons, radio stations, a direction finder, a gyrocompass... Solov, in the Soviet “esques” there was not a single foreign-made bolt. The result was a maneuverable and fast ship, distinguished by a rational layout and balanced design, powerful weapons, and excellent performance and seaworthiness. 
But, oddly enough, neither the high performance nor the most powerful weapons made the Eski an effective weapon - most of the victories were won with the help of deployed mines.
The reasons for the failures lie in the tactics of using “Esoks” - submarine cruisers created for the ocean expanses had to “tread water” in the shallow Baltic “puddle”. Operating at depths of 20 to 30 meters, the 77-meter boat could hit the ground with its bow while its stern would still be sticking out on the surface.
Things were much better in the Northern Fleet, where the S-56 boat under the command of G.I. became famous. Shchedrin.

So, S_56 was laid down in 1936 at the Andre Marty shipyard (now the Admiralty Shipyards) in Leningrad. Then it was dismantled into pieces and railway they were delivered in sections across the country - to Vladivostok, to plant No. 202 (Dalzavod named after K. Voroshilov), where they were again welded into a single whole. And they launched it in December 1939.
Commander of the submarine C-56, captain 2nd rank Grigory Ivanovich Shchedrin.
Captain Shchedrin later recalled: “The members of the acceptance committee simultaneously started the stopwatches. My job is to control the ship... We ventilate the rapid dive tank, stay at a given depth... The standard set by the designers has been met and exceeded... We have to dive to the maximum depth. We dive “whatnot”, that is, we linger at depths, first every twenty, and then ten meters. Everything is going as well as possible - the boat is completely sealed, only occasionally it is necessary to tighten one or another seal to eliminate drip leakage of water. People are doing great. Most of them were at such depths for the first time, and yet I did not see any signs of excitement on any face - such is the power of confidence in one’s technique. They laid down on the ground at a depth of five meters exceeding the official limit. We tested the pumps and outboard fittings - everything works fine. The strong hull, its frame, the plating sheets - these steel muscles of the ship, as they are often called, did not utter a single “moan”. Good steel the workers cooked it!”

Already in October 1942, the S-56, under the command of Captain Shchedrin, set out on a transoceanic crossing along the route: Vladivostok - San Francisco (USA) - Panama Canal - Halifax (Canada) - Rosyth (Scotland) - Polar (USSR). The hike took 67 days. During which time the submariners survived one attack by a Japanese submarine and two attacks by the German Kriegsmarine, and twice got into accidents due to their own negligence. As a result, the submariners, having completed 16,632 nautical miles(including 113 nautical miles under water), became part of the 2nd division of the Northern Fleet submarine brigade. That is, the submariners essentially traveled around the world - and all so that the boat, made in Leningrad, would reach the base near Murmansk.

During the Great Patriotic War, the S-56 was the most productive Soviet submarine. S-56 submariners made 8 combat missions, carried out 13 attacks with the release of 30 torpedoes, sinking 4 ships (2 warships and 2 transports) and damaging one. In 1944, the S-56 boat was awarded the Order of the Red Banner for military services. On February 23, 1945, the submarine was awarded the Guards title. During the Great Patriotic War, the S-56 was declared lost 19 times.
For comparison: Otto Kretschmer of the Kriegsmarine, commander of U-23, the most successful submariner of World War II, sank 44 ships, including 1 destroyer. However, this comparison speaks not so much about the poor training of Soviet sailors, but about the fact that they were opposed by the most professional army and navy in the world.
But the Soviet sailors survived thanks to their survivability: during the Great Patriotic War, the S-56 was declared dead 19 times.
Captain 2nd rank I.F. Kucherenko hands over to the commander of the S-56, Captain 3rd Rank G.I. Shchedrin medal "For the defense of the Arctic." Also for the successful command of the submarine and the personal courage and heroism shown at the same time, captain 2nd rank Shchedrin G.I. By Decree of the Presidium Supreme Council On November 5, 1944, the USSR was awarded the title of Hero of the Soviet Union with the presentation of the Order of Lenin and the medal " Golden Star" The S-56 submarine was awarded the Order of the Red Banner on March 31, 1944, and was awarded the Guards rank on February 23, 1945.
After World War II, the S-56 continued to serve in the Northern Fleet. In 1954, the boat made another transoceanic crossing - along the Northern Sea, from Murmansk to Vladivostok.
In 1955 the boat was removed from combat personnel, disarmed and converted into a floating charging station - for charging the batteries of other boats.
Only 20 years later, in 1975, they remembered the heroic boat. In honor of the 30th anniversary of the Victory, the boat was pulled ashore and cut into pieces again. Then parts of the boat were installed on the foundation on Korabelnaya Embankment, next to the Pacific Fleet headquarters building on the shore of Zolotoy Rog Bay. 
The parts were docked and connected - already as a museum ship.

Submarines dictate the rules in naval warfare and force everyone to meekly follow the routine. Those stubborn people who dare to ignore the rules of the game will face a quick and painful death in the cold water, among the wreckage and oil stains. Boats, regardless of flag, remain the most dangerous combat vehicles, capable of crushing any enemy. I bring to your attention a short story about the seven most successful submarine projects of the war years.
Boats type T (Triton-class), UK
The number of submarines built is 53.
Surface displacement - 1290 tons; underwater - 1560 tons.
Crew - 59…61 people.
Working immersion depth - 90 m (riveted hull), 106 m (welded hull).
Full surface speed - 15.5 knots; in underwater - 9 knots.
A fuel reserve of 131 tons provided a surface cruising range of 8,000 miles.
Weapons:
- 11 torpedo tubes of 533 mm caliber (on boats of subseries II and III), ammunition - 17 torpedoes;
- 1 x 102 mm universal gun, 1 x 20 mm anti-aircraft "Oerlikon".
A British underwater Terminator capable of knocking the crap out of any enemy's head with a bow-launched 8-torpedo salvo. The T-type boats had no equal in destructive power among all the submarines of the WWII period - this explains their ferocious appearance with a bizarre bow superstructure, where additional torpedo tubes were located.
The notorious British conservatism is a thing of the past - the British were among the first to equip their boats with ASDIC sonars. Alas, despite their powerful weapons and modern detection means, the T-class high seas boats did not become the most effective among the British submarines of World War II. Nevertheless, they went through an exciting battle path and achieved a number of remarkable victories. “Tritons” were actively used in the Atlantic, in the Mediterranean Sea, destroyed Japanese communications in the Pacific Ocean, and were spotted several times in the frozen waters of the Arctic.
In August 1941, the submarines "Tygris" and "Trident" arrived in Murmansk. British submariners demonstrated a master class to their Soviet colleagues: in two trips, 4 enemy ships were sunk, incl. "Bahia Laura" and "Donau II" with thousands of soldiers of the 6th Mountain Division. Thus, the sailors prevented the third German attack on Murmansk.
Other famous T-boat trophies include the German light cruiser Karlsruhe and the Japanese heavy cruiser Ashigara. The samurai were “lucky” to get acquainted with a full 8-torpedo salvo of the Trenchent submarine - having received 4 torpedoes on board (+ another one from the stern tube), the cruiser quickly capsized and sank.
After the war, the powerful and sophisticated Tritons remained in service with the Royal Navy for another quarter of a century.
It is noteworthy that three boats of this type were acquired by Israel in the late 1960s - one of them, INS Dakar (formerly HMS Totem) was lost in 1968 in the Mediterranean Sea under unclear circumstances.
Boats of the "Cruising" type XIV series, Soviet Union
The number of submarines built is 11.
Surface displacement - 1500 tons; underwater - 2100 tons.
Crew - 62…65 people.
Full surface speed - 22.5 knots; in underwater - 10 knots.
Surface cruising range 16,500 miles (9 knots)
Submerged cruising range - 175 miles (3 knots)
Weapons:
- 2 x 100 mm universal guns, 2 x 45 mm anti-aircraft semi-automatic guns;
- up to 20 minutes of barrage.
...On December 3, 1941, German hunters UJ-1708, UJ-1416 and UJ-1403 bombed a Soviet boat that tried to attack a convoy at Bustad Sund.
- Hans, can you hear this creature?
- Nain. After a series of explosions, the Russians lay low - I detected three impacts on the ground...
-Can you determine where they are now?
- Donnerwetter! They are blown away. They probably decided to surface and surrender.
The German sailors were wrong. From the depths of the sea, a MONSTER rose to the surface - the cruising submarine K-3 series XIV, unleashing a barrage of artillery fire on the enemy. With the fifth salvo, Soviet sailors managed to sink U-1708. The second hunter, having received two direct hits, began to smoke and turned to the side - his 20 mm anti-aircraft guns could not compete with the “hundreds” of the secular submarine cruiser. Scattering the Germans like puppies, K-3 quickly disappeared over the horizon at 20 knots.
The Soviet Katyusha was a phenomenal boat for its time. Welded hull, powerful artillery and mine-torpedo weapons, powerful diesel engines (2 x 4200 hp!), high surface speed of 22-23 knots. Huge autonomy in terms of fuel reserves. Remote control of ballast tank valves. A radio station capable of transmitting signals from the Baltic to the Far East. An exceptional level of comfort: shower cabins, refrigerated tanks, two seawater desalinators, an electric galley... Two boats (K-3 and K-22) were equipped with Lend-Lease ASDIC sonars.
But, oddly enough, neither the high characteristics nor the most powerful weapons made the Katyusha an effective weapon - in addition to the dark story of the K-21 attack on the Tirpitz, during the war years the XIV series boats accounted for only 5 successful torpedo attacks and 27 thousand br. reg. tons of sunk tonnage. Most of the victories were achieved with the help of mines. Moreover, its own losses amounted to five cruising boats.
The reasons for the failures lie in the tactics of using Katyushas - the powerful submarine cruisers, created for the vastness of the Pacific Ocean, had to “tread water” in the shallow Baltic “puddle”. When operating at depths of 30-40 meters, a huge 97-meter boat could hit the ground with its bow while its stern was still sticking out on the surface. It was not much easier for the North Sea sailors - as practice has shown, the effectiveness of the combat use of Katyushas was complicated by the poor training of personnel and the lack of initiative of the command.
It's a pity. These boats were designed for more.
“Baby”, Soviet Union
Series VI and VI bis - 50 built.
Series XII - 46 built.
Series XV - 57 built (4 took part in combat operations).
Performance characteristics of boats type M series XII:
Surface displacement - 206 tons; underwater - 258 tons.
Autonomy - 10 days.
Working immersion depth - 50 m, maximum - 60 m.
Full surface speed - 14 knots; in underwater - 8 knots.
Cruising range on the surface is 3,380 miles (8.6 knots).
Submerged cruising range is 108 miles (3 knots).
Weapons:
- 2 torpedo tubes of 533 mm caliber, ammunition - 2 torpedoes;
- 1 x 45 mm anti-aircraft semi-automatic.
The project of mini-submarines for the rapid strengthening of the Pacific Fleet - the main feature of the M-type boats was the ability to be transported by rail in a fully assembled form.
In the pursuit of compactness, many had to be sacrificed - service on the Malyutka turned into a grueling and dangerous undertaking. Difficult living conditions, strong roughness - the waves mercilessly tossed the 200-ton “float”, risking breaking it into pieces. Shallow diving depth and weak weapons. But the main concern of the sailors was the reliability of the submarine - one shaft, one diesel engine, one electric motor - the tiny “Malyutka” left no chance for the careless crew, the slightest malfunction on board threatened death for the submarine.
The little ones quickly evolved - the performance characteristics of each new series were several times different from the previous project: the contours were improved, the electrical equipment and detection equipment were updated, the dive time was reduced, and the autonomy increased. The “babies” of the XV series no longer resembled their predecessors of the VI and XII series: one-and-a-half-hull design - the ballast tanks were moved outside the durable hull; The power plant received a standard two-shaft layout with two diesel engines and underwater electric motors. The number of torpedo tubes increased to four. Alas, Series XV appeared too late - the “Little Ones” of Series VI and XII bore the brunt of the war.
Despite their modest size and only 2 torpedoes on board, the tiny fish were simply distinguished by their terrifying “gluttony”: in just the years of World War II, Soviet M-type submarines sank 61 enemy ships with a total tonnage of 135.5 thousand gross tons, destroyed 10 warships, and also damaged 8 transports.
The little ones, originally intended only for operations in the coastal zone, have learned to fight effectively in open sea areas. They, along with larger boats, cut enemy communications, patrolled at the exits of enemy bases and fjords, deftly overcame anti-submarine barriers and blew up transports right at the piers inside protected enemy harbors. It’s simply amazing how the Red Navy were able to fight on these flimsy ships! But they fought. And we won!
Boats of the “Medium” type, series IX-bis, Soviet Union
The number of submarines built is 41.
Surface displacement - 840 tons; underwater - 1070 tons.
Crew - 36…46 people.
Working immersion depth - 80 m, maximum - 100 m.
Full surface speed - 19.5 knots; submerged - 8.8 knots.
Surface cruising range 8,000 miles (10 knots).
Submerged cruising range 148 miles (3 knots).
“Six torpedo tubes and the same number of spare torpedoes on racks convenient for reloading. Two cannons with large ammunition, machine guns, explosive equipment... In a word, there is something to fight with. And 20 knots surface speed! It allows you to overtake almost any convoy and attack it again. The technique is good...”
- opinion of the commander of the S-56, Hero of the Soviet Union G.I. Shchedrin
The Eskis were distinguished by their rational layout and balanced design, powerful armament, and excellent performance and seaworthiness. Initially a German project from the Deshimag company, modified to meet Soviet requirements. But don’t rush to clap your hands and remember the Mistral. After the start of serial construction of the IX series in Soviet shipyards, the German project was revised with the goal of a complete transition to Soviet equipment: 1D diesel engines, weapons, radio stations, a noise direction finder, a gyrocompass... - there were none in the boats designated “series IX-bis”. foreign made bolt!
The problems with the combat use of "Medium" type boats, in general, were similar to the K-type cruising boats - locked in mine-infested shallow water, they were never able to realize their high combat qualities. Things were much better in the Northern Fleet - during the war, the S-56 boat under the command of G.I. Shchedrina made the transition through the Pacific and Atlantic oceans, moving from Vladivostok to Polyarny, subsequently becoming the most productive boat of the USSR Navy.
An equally fantastic story is connected with the S-101 “bomb catcher” - during the war years, the Germans and Allies dropped over 1000 depth charges on the boat, but each time the S-101 returned safely to Polyarny.
Finally, it was on the S-13 that Alexander Marinesko achieved his famous victories.
Gato type boats, USA
The number of submarines built is 77.
Surface displacement - 1525 tons; underwater - 2420 tons.
Crew - 60 people.
Working immersion depth - 90 m.
Full surface speed - 21 knots; submerged - 9 knots.
Cruising range on the surface is 11,000 miles (10 knots).
Submerged cruising range 96 miles (2 knots).
Weapons:
- 10 torpedo tubes of 533 mm caliber, ammunition - 24 torpedoes;
- 1 x 76 mm universal gun, 1 x 40 mm Bofors anti-aircraft gun, 1 x 20 mm Oerlikon;
- one of the boats, USS Barb, was equipped with a multiple launch rocket system for shelling the coast.
Ocean-going submarine cruisers of the Getou class appeared at the height of the war in the Pacific Ocean and became one of the most effective tools of the US Navy. They tightly blocked all strategic straits and approaches to the atolls, cut all supply lines, leaving Japanese garrisons without reinforcements, and Japanese industry without raw materials and oil. In battles with the Gatow, the Imperial Navy lost two heavy aircraft carriers, lost four cruisers and a damn dozen destroyers.
High speed, lethal torpedo weapons, the most modern radio equipment for detecting the enemy - radar, direction finder, sonar. The cruising range allows for combat patrols off the coast of Japan when operating from a base in Hawaii. Increased comfort on board. But the main thing is the excellent training of the crews and the weakness of Japanese anti-submarine weapons. As a result, the "Getow" mercilessly destroyed everything - it was they who brought victory in the Pacific Ocean from the blue depths of the sea.
...One of the main achievements of the Getow boats, which changed the whole world, is considered to be the event of September 2, 1944. On that day, the Finback submarine detected a distress signal from a falling plane and, after many hours of searching, found a frightened and already desperate pilot in the ocean . The one who was saved was one George Herbert Bush.
Electric robots type XXI, Germany
By April 1945, the Germans managed to launch 118 submarines of the XXI series. However, only two of them were able to achieve operational readiness and go to sea in the last days of the war.
Surface displacement - 1620 tons; underwater - 1820 tons.
Crew - 57 people.
Working depth of immersion is 135 m, maximum depth is 200+ meters.
Full speed in the surface position is 15.6 knots, in the submerged position - 17 knots.
Cruising range on the surface is 15,500 miles (10 knots).
Submerged cruising range 340 miles (5 knots).
Weapons:
- 6 torpedo tubes of 533 mm caliber, ammunition - 17 torpedoes;
- 2 Flak anti-aircraft guns of 20 mm caliber.
Our allies were very lucky that all the forces of Germany were sent to the Eastern Front - the Krauts did not have enough resources to release a flock of fantastic “Electric Boats” into the sea. If they appeared a year earlier, that would be it! Another turning point in the Battle of the Atlantic.
The Germans were the first to guess: everything that shipbuilders in other countries are proud of - large ammunition, powerful artillery, high surface speed of 20+ knots - is of little importance. The key parameters that determine the combat effectiveness of a submarine are its speed and cruising range when submerged.
Unlike its peers, “Electrobot” was focused on being constantly under water: a maximally streamlined body without heavy artillery, fences and platforms - all for the sake of minimizing underwater resistance. Snorkel, six groups of batteries (3 times more than on conventional boats!), powerful electric. Full speed engines, quiet and economical electric. "sneak" engines.
The Germans calculated everything - the entire Elektrobot campaign moved at periscope depth under the RDP, remaining difficult to detect for enemy anti-submarine weapons. At great depths, its advantage became even more shocking: 2-3 times greater range, at twice the speed of any wartime submarine! High stealth and impressive underwater skills, homing torpedoes, a set of the most advanced detection means... “Electrobots” opened a new milestone in the history of the submarine fleet, defining the vector of development of submarines in the post-war years.
The Allies were not prepared to face such a threat - as post-war tests showed, the “Electrobots” were several times superior in mutual hydroacoustic detection range to the American and British destroyers guarding the convoys.
Type VII boats, Germany
The number of submarines built is 703.
Surface displacement - 769 tons; underwater - 871 tons.
Crew - 45 people.

703 submarines. 10 MILLION tons of sunk tonnage! Battleships, cruisers, aircraft carriers, destroyers, corvettes and enemy submarines, oil tankers, transports with aircraft, tanks, cars, rubber, ore, machine tools, ammunition, uniforms and food... The damage from the actions of German submariners exceeded all reasonable limits - if only Without the inexhaustible industrial potential of the United States, capable of compensating for any losses of the allies, German U-bots had every chance to “strangle” Great Britain and change the course of world history.
The successes of the Sevens are often associated with the “prosperous times” of 1939-41. - allegedly, when the Allies appeared the convoy system and Asdik sonars, the successes of the German submariners ended. A completely populist statement based on a misinterpretation of “prosperous times.”
The situation was simple: at the beginning of the war, when for every German boat there was one Allied anti-submarine ship, the “sevens” felt like invulnerable masters of the Atlantic. It was then that the legendary aces appeared, sinking 40 enemy ships. The Germans already held victory in their hands when the Allies suddenly deployed 10 anti-submarine ships and 10 aircraft for each active Kriegsmarine boat!

The whole history of the German “seven” is a formidable warning from the past: what threat does a submarine pose and how high are the costs of creating an effective system to counter the underwater threat.
The submarine fleet of the Kriegsmarine of the Third Reich was created on November 1, 1934 and ceased to exist with the surrender of Germany in World War II. During its relatively short existence (about nine and a half years), the German submarine fleet managed to fit itself into military history as the largest and deadliest submarine fleet of all time. German submarines, which inspired terror in sea captains from the North Cape to the Cape of Good Hope and from Caribbean Sea to the Strait of Malacca, thanks to memoirs and films, they have long turned into one of the military myths, behind the veil of which real facts often become invisible. Here are some of them.
1. The Kriegsmarine fought with 1,154 submarines built in German shipyards (including the submarine boat U-A, which was originally built in Germany for the Turkish Navy). Of the 1,154 submarines, 57 submarines were built before the war, and 1,097 were built after September 1, 1939. The average rate of commissioning of German submarines during World War II was 1 new submarine every two days.

2. The Kriegsmarine fought with 21 types of German-built submarines with the following technical characteristics:
Displacement: from 275 tons (type XXII submarines) to 2710 tons (type X-B);
Surface speed: from 9.7 knots (XXII type) to 19.2 knots (IX-D type);
Submerged speed: from 6.9 knots (type II-A) to 17.2 knots (type XXI);
Immersion depth: from 150 meters (type II-A) to 280 meters (type XXI).

2 Norwegian: B-5 (as part of the Kriegsmarine - UC-1), B-6 (as part of the Kriegsmarine - UC-2);
5 Dutch: O-5 (before 1916 - British submarine H-6, in the Kriegsmarine - UD-1), O-12 (in the Kriegsmarine - UD-2), O-25 (in the Kriegsmarine - UD-3 ), O-26 (as part of the Kriegsmarine - UD-4), O-27 (as part of the Kriegsmarine - UD-5);
