The submarines of the Soviet and Russian Navy, numbered M-6, M-7, M-8, M-9 and M-10, are lined up in the southern waters of Peter the Great Bay, they belong to the "baby" class of small submarines, their underwater displacement is only 200 tons, because of the use of single-shaft propulsion, slow speed, and small combat radius, they are usually used for coastal defense operations. Pen? Interesting? Pavilion wWw. ｂiquge。 infoThis time, they were no longer facing the Japanese light ships that came to scout and harass, but the Japanese Combined Fleet, which ranked among the top three in the world in terms of combat effectiveness.

Although the Russian Navy has never really been in the first ranks, they have a long history of building and using submarines. As early as May 1834, the Alexander Loveski Shipyard in St. Petersburg, Russia built the world's first submarine made of metal, it was designed by the Russian Imperial Chamberlain Military Attache Alexander Andreevich Hilde, the boat has a surface displacement of 16 tons, a safe diving depth of 12 meters, through the crew with both hands to shake the wheel wings to obtain forward momentum, the underwater speed is only half a knot, the use of lead ballast placed in the bow and stern groove and two pressurized water tanks to achieve floating and diving, the crew through a copper pipe from the sea surface to obtain air, and the only weapon the boat was equipped with was a mine. From the perspective of the 20th century, this "Hilde" submarine is rudimentary and incompetent, but in the first half of the 19th century, it is already quite a masterpiece by the level of technology and knowledge.

In the second half of the 19th century, the Russians continued to maintain a leading position in the field of submarines. In 1866, submarines of the "Alexander Lovevsky" type, which had most of the basic elements of modern submarines, were built. More than a decade later, Devitsky 1 and 2 were launched, the latter not only equipped with a rudimentary optical periscope, but also became the world's first submarine to be built in mass - the Russian government ordered 50 of them, and all of them were built.

After the victory of the revolution, the Russian Soviet government not only received submarines from Tsarist Russia, but also inherited the importance attached to this weapon of naval warfare. In the twenties and thirties, due to the lack of sufficient funds and technology to develop the ocean-going fleet, the Soviet and Russian navies focused on submarines, torpedo boats, and aviation, and the "Decembrist", "Leninist", "Barracuda", and "Truth" classes with relatively good performance were put into service one after another. In the mid-thirties, with the sudden increase in assistance from the United States and the British camp, Soviet Russia quickly finalized the construction of a large number of "baby" class small submarines and "S" class medium submarines, which greatly strengthened the combat capability of the Soviet and Russian navies......

The Russian Navy in 1942 was certainly not to be underestimated, and their opponents were also transformed. Plagued by the lack of anti-submarine forces in the Pacific War, the Japanese Navy has designed and built hundreds of new destroyers since 1936, developed its own high-performance sonar equipment, and copied the German-style deep-bomb launch system. At the beginning of the Japanese-Soviet war, these destroyers quickly played a role, sinking more than a dozen Soviet and Russian submarines and capturing two in the waters around the Japanese archipelago in just two months, forcing the Soviet and Russian navies to send the "Kirov" large cruiser to battle one after another. After the sinking of the "Kirov", the Soviet and Russian Pacific Fleets could only rely on submarines to break diplomatic relations, and the threat to the Japanese sea shipping lines was weakening day by day. Because of this, when the Japanese Combined Fleet descended like a dark cloud to the southern part of Peter the Great Bay, and suppressed the Russian air force stationed in Vladivostok with a powerful carrier-based air group, few expected these humble small submarines to turn the tide of the war.

The cost of a "baby" class submarine is only 400,000 gold rubles, less than half the price of a Japanese destroyer, their main weapons are two 533 mm torpedo tubes, and the whole boat is only equipped with two torpedoes, the threat to the Japanese fleet seems indeed insignificant, but the technical weapons introduced by the Soviet and Russian governments at a high price have changed their fate, and even affected the course of this naval campaign!

The Soviet Russian submarine numbered M-6, in addition to the 17 crew members that are regularly equipped, also carries an additional foreign aid. This man came from the German Navy, and was an active non-commissioned officer, who traveled thousands of miles to the Far East and risked his life to participate in the battles of the Soviet Russian Navy, because he had a special mission - to fulfill the secret dealings between Germany and Soviet Russia.

One of the protagonists of the classified deal, the G-11 wire-guided torpedo, was lying quietly in the No. 1 torpedo tube of the M-6. The most unusual thing about these torpedoes is that they use advanced wire guide technology, which is only available to Germany and Ireland today. The standard version of the G-11 torpedo had a maximum range of 6 km, and in order to match the torpedo tube specifications of the Russian submarines, the Germans quickly created a 533 mm torpedo tube firing device for Russian ships and a Russian version of the G-11 torpedo with a length of 20 inches - their effective range at 30 knots was correspondingly reduced to 5 km, and even so, judging by the experience of the Atlantic and Pacific wars in the mid-30s, these hidden arrows in the sea were enough to pose a deadly threat to enemy ships!

In fact, the control technology of the wire-guided torpedo is not complicated at all, the launcher and the torpedo each have a pay-off device, and the pay-off mechanism is a spool, and the wire is usually wound on the spool. Since the length of the wire is calculated in kilometers, even if the outer diameter is small, the volume after being entangled is not small, if it is arranged on the torpedo, it will undoubtedly affect the speed and maneuverability of the torpedo, so the torpedo comes with one-third of the wire, and the external pay-off on the firing mechanism loads the rest of the wire. The external pay-off device is usually fixed at the tail of the torpedo, and when fired, it is loaded into the launch tube together with the torpedo, and is connected to the control device of the launch platform through a special socket on the back cover of the launch tube. After the torpedo is launched, the external pay-off device is left in the launch tube, the front cover of the torpedo launch tube is not closed, and the two pay-off devices are paid off at the same time, so that the pay-off rate can be accelerated to ensure that the force on the wire is minimized, and the wire will not be broken because the difference between the launch rate and the pay-off rate is too large. The operator observes the trajectory of the target ship through the periscope, so as to adjust the direction of the wire-guided torpedo to make it hit the target - for the purpose of observing the torpedo track, the G-11 uses a traditional thermal power unit instead of a silent electric motor, which correspondingly increases the probability of the torpedo being discovered by the enemy ship during the attack and evading and blocking it.

Under the strict defense of Japanese destroyers and submarine hunters, this submarine attack team of the Soviet and Russian Navy not only found it difficult to find opportunities to get close to the main ships of the Japanese army, but was repeatedly attacked by opponents. Under these circumstances, the M-6 commander decisively abandoned the original plan to attack the large Japanese ships, and instead targeted the Japanese ships of the cruiser class. It didn't take long for a Japanese battleship with a simple silhouette and smooth lines to sail quickly from the sea in front of it, and as it adjusted its course halfway, the long side side was presented in front of the eyes of the Soviet and Russian captains, who quickly recognized that it was the Japanese Navy's Agano-class light cruisers built in batches after the war, although the tactical value was not as good as those heavy cruisers, but it was also a new warship built by the Japanese Navy at a cost of tens of millions of yen.

The opportunity was not to be lost, and the Russian captain ordered the attack when the enemy ships were about 4,000 meters away. According to the pre-agreed strategy, the M-6 first fired the ordinary torpedo in the No. 2 torpedo tube, and then fired the G-11 in the No. 1 torpedo tube a few seconds later, and this wire-guided torpedo was naturally controlled by a German naval non-commissioned officer with rich practical experience, who stared at the periscope observation port with both eyes and held the torpedo control box in both hands, and remained motionless for the first two or three minutes, until the final stage was adjusted in a slight amplitude.

The wire-guided torpedo hits the target with a bang!

Without waiting for the Russian crew to celebrate, the German naval non-commissioned officer shouted in jerky Russian: "Put away the periscope!" Dive fast! ”

As soon as the Germans finished speaking, the sonar soldier in the submarine hurriedly said: "The high-speed propeller is approaching!" ”

As soon as the submarine began to dive, the huge impact of the bursting depth charges hit me. The design and construction of the "baby" has been greatly assisted by American and British experts, both the performance indicators and the cost have met the requirements of the Soviet and Russian Navy, but they were not used to resist the enemy's anti-submarine ships from the beginning, so when they are attacked by the enemy's deep bombs, the best way to survive is to dive to the maximum safe depth or lie quietly on the bottom of the sea, hoping that their small and flexible bodies can avoid the sonar detection of enemy ships.

In the end, it was not the size advantage of the "Baby" class submarine that allowed the M-6 to retreat after the attack, but another technical weapon imported by the Soviet Russian government from the Western allies during the war, the Irish radio-guided bomb. Due to the short time to equip the Soviet Russian army, the Irish technicians did not have time to provide sufficient instruction and training to the Soviet and Russian officers and soldiers, so in this very critical battle, many Irish soldiers participated in the war as volunteers, and this was of course instructed by the Irish high-level......

In the first wave of tactical counterattacks launched by the Soviet and Russian forces with land-based bombers, a total of 3 medium bombers and 1 attack aircraft were equipped with so-called flying bombs codenamed "Angel-II", that is, radio-guided bombs. Since the start of the project in 1924, the Irish have been engaged in research and development for 18 years on this project that has received little attention from the outside world, from the experimental Angel-I to the official production version of Angel-II, the Irish Air Force took the lead in getting the stepping stone to the threshold of the modern air force, and selling it to the Soviet Russian government not only brought a rich return for Ireland, but also became a key for the Irish top to exert influence on the pattern of war and even the world order.

In its first actual combat operation, the "Angel-II" achieved two strikes in four hits, and it was the Japanese main battleship "Tosa" and the main aircraft carrier "Akaryu" that were under the protection of strict anti-aircraft fire, which greatly shocked the Japanese navy top brass and even the Japanese army base camp. In their view, the army could compete with the Russians, but the navy should not suffer heavy losses on the Russians, otherwise they would be at a disadvantage in dealing with the eastward advance of the Western Allies and the rearmament of the United States.
