God, the battle situation has changed slightly.

The South Korean Air Force adjusted its tactics and did not continue to attack the Japanese aircraft carrier battle group and amphibious combat fleet. Instead, it dispatched a large number of fighter planes to launch missiles at the Japanese army on Dokdo Island in the airspace near Yuling Island and threw long-range guided bombs. The South Korean Navy dispatched 3~ large transport ships to transport an artillery battalion equipped with long-range rocket launchers and tens of thousands of large-caliber long-range rockets to Yuling Island, preparing to launch long-range artillery bombardment on Dokdo Island.

The tactic of "fighting a cow across the mountain" has achieved results.

Because Yuling Island is recognized as South Korean territory, if Japan bombs Yuling Island or attacks South Korean combat aircraft flying over Yuling Island, the United States has reason to join the war, so Japan is very "restrained" and does not launch a counterattack or even faces head-on battle with the South Korean Air Force.

This is also a very helpless tactic. If there is another choice, South Korea will not do this.

According to Japan, South Korea adopted a "despicable" tactic, proving that South Korea gave up the idea of ​​"invading" Dokdo.

This day was not easy for the Japanese soldiers who boarded Dokdo.

The South Korean Air Force bombed very frequently. Every few minutes, a missile or a bomb fell on Dokdo Island, which made Japanese officers and soldiers worried and had to prepare to rush to the nearest air defense bunker at any time. From 16:30, South Korean artillery joined the battle and threw thousands of rockets to the East Island (there are mainly two large islands in the east and west of Dokdo Island). Although more than half of the rockets landed on the sea, one Japanese army was still killed. Subsequently, several rockets fell down every minute, forcing the Japanese army to speed up the excavation of air defense bunkers.

When the war reaches this point, South Korea is in a dilemma.

For Park Tae-hyun, if he admits "defeated in the war", the angry public opinion will immediately drive him out of the Blue House; if he continues to fight, South Korea's national strength and Korean society will be severely tested in the war.

If you fight, you can't win, and if you don't fight, you can't explain to the people.

Just when everyone thought the situation was settled, the situation suddenly changed at night.

About the point, the battle group of the Akagi aircraft carrier "Akagi" (Japanese aircraft carriers named Akagi and Kaga respectively) was attacked by a submarine. At least one heavy torpedo hit the Akagi. Another torpedo hit the Akagi air defense destroyer "Legend" less than 3 nautical miles away from the Akagi Islands. 2~ The ground fire lit up on the warship illuminated the night sky. It is clearly visible on the Hidden Islands dozens of kilometers away.

In the early morning of the 5th, South Korean President Park Tae-hyun personally announced that the naval submarine sank one Japanese aircraft carrier and one destroyer each!

That night, almost all Koreans suffered from insomnia.

By dawn, in just a few hours, hundreds of thousands of emotions gathered outside the Presidential Palace of Blue House. They held high the Korean flag and the presidential portrait poster, shouting the slogan "Long live the Korean nation".

The actual situation will definitely disappoint all Koreans.

At 8 o'clock, Sada Murakami announced to the Japanese reporters at the Prime Minister's Office that the USS Akagi aircraft carrier and the destroyer Ligan were attacked by a submarine, both of which were severely damaged and were on their way back to the Tsuruga Naval Base.

Subsequently, Japanese TV broadcast videos taken by two warships during damage management and fire extinguishing.

Whether the Koreans believe it or not, the Akagi aircraft carrier and the Ligan destroyer did not sink, but were only severely damaged. The reconnaissance satellites of the Republic and the United States took photos of warships returning with injuries under the cover of other warships.

It seemed that in order to save face, Park Tae-hyun immediately announced that South Korea would launch a large-scale combat operation to annihilate the Japanese fleet.

The South Korean president made a "obedience", but for this brief conflict, the two severely damaged warships have lost their combat capabilities, which is not much different from being sunk.

Afterwards, it was proved that both the Akagi and the Ligan were almost sunk, and all the Korean submarines lacked was a little luck.

The central thunder point of the "Akagi" is near the keel of No. 2311, which is close to the stern of the ship. Because of the defects in design, one torpedo almost exploded the propulsion axis of the "Akagi". Although the "Akagi" is equipped with an auxiliary power propulsion system, even if all the main propulsion axis are blown off, it can still return at a speed of 2 knots. However, there was a second torpedo at that time that was shooting at the "Akagi" and almost hit the "Akagi". If all the main propulsion axis is blown off, the "Akagi" will be doomed.

During the return journey, the "Achihe" used an auxiliary power propulsion system.

The problem with the "Akagi" is not just the propulsion system. Because the aircraft carrier has not been designed for decades, a large number of Japanese shipbuilding engineers and technicians have been exiled overseas during the turmoil. Therefore, when designing the "Akagi" site, Japan had to "start from scratch". Except for technologies such as electromagnetic catapults introduced from the United States, almost all work has to be started from scratch.

Compared with ordinary local warships, medium-sized aircraft carriers with displacement of more than tons are much more complex.

When designing the watertight structure of the hull, Japanese engineers had to adopt many "tricks" in order to control the displacement within the specified range. As it turns out, there is no warship survivability.

"You can find out what you pay for, and "cutting corners" will eventually have consequences.

Not to mention anything else, the United States has proposed to develop small aircraft carriers many times over the past decades, but eventually gave up. It is still building a super aircraft carrier with a displacement of more than 1 ton. While significantly reducing the scale of aircraft carrier-based aircraft, the United States has not reduced the displacement of aircraft carriers in order to maximize the survival ability of aircraft carriers.

Due to the defects in the watertight structure, the water inlet of the "Achihe" exceeded the amount of water inlet for several hours after the thunder.

In order to reduce weight, in addition to letting all the carrier-based aircraft on the aircraft carrier fly back to the land airport, the captain of the "Akagi" also threw the ammunition on the aircraft carrier into the sea or transferred it to the supply ship that came to pick up, and ordered the air kerosene tank to evacuate the aircraft carrier's kerosene tanks and do everything possible to increase the reserve buoyancy of the aircraft carrier.

As the water inlet at the tail increases, in order to maintain longitudinal balance, the captain has to order water injection into the front ballast tank.

In order to reduce the displacement, in addition to using the water pumps provided by the Akagi, several water pumps were also sent from the warships that accompanied the escort, and the power provided by other warships was used to extract the sea water in the ship.

When the Akagi returned to the Tsuruga Naval Base, the flight deck was less than 5 meters away from the water!

It can be said that the "Chengcheng" has recovered a life.

For a medium-sized aircraft carrier with a displacement of more than tons, the survival performance of the Akagi is indeed very poor. In the Fourth India-Pakistan War 7 years ago, the "performance" of the Indian Navy's 2-medium aircraft carriers far exceeded that of the Akagi and was not sunk by a torpedo.

There is no doubt that the actual survivability of the "Akagi" is far from meeting the design indicators of the Japanese Ministry of Defense.

After returning to the Turga Naval Base, the overhaul of the Akagi was underway for 23 months, far exceeding the outside world's expected 8 months. The expenditure of the overall overhaul reached 65% of the construction funds of the Akagi, which is not much less than the rebuilding of an aircraft carrier. Taking this opportunity, the Japanese Navy made comprehensive improvements to the Akagi, mainly to improve the survivability of the aircraft carrier. The standard displacement of the Akagi, after the improvement, exceeded 50,000 tons, and the maximum speed was reduced by 3 knots.

The poor performance of the "Akagi" not only caused the Japanese Navy to suspend the construction of 2-medium aircraft carriers, but also proposed a plan to build a large aircraft carrier at the end of the year.

Because large aircraft carriers need to be built as soon as possible, the Kaga did not make comprehensive improvements like the Akagi.

The situation of the destroyer "Ligan" was even worse. The explosion point of the heavy torpedo was still near the stern of the ship, and 2~main propulsion axis was broken. Fortunately, the one that shot at "Ligan" was a torpedo that "off-target" when attacking "Akagi". No second torpedo threatened the destroyer "Ligan".

It can be said that the survival of the "Legend" is not only fortunate, but also a miracle.

As a destroyer with a standard displacement of only more than 6,000 tons, it is a huge miracle that can withstand the direct attack of a heavy anti-ship torpedo.

Generally speaking, a heavy torpedo with a weight of more than 250 kg (the charge amount is about half the weight of the thunderhead, but the torpedo uses high-energy explosives, and the explosion power is far greater than that of ordinary explosives). When hitting the keel of the ship, it is enough to sink a 10,000-ton warship.

The reason why the "Ligan" did not sink is that the torpedo hit point is too far behind, and above the explosion point is a propulsion system with key protection. If the explosion point moves forward 50 meters, the "Ligan" is likely to be blown into two pieces on the spot, and there is no chance of struggling.

When they returned to the Tsunaga Naval Base, the stern of the ship "Ligan" had been flooded with sea water.

After months of comprehensive inspections and evaluations, Japan finally gave up the idea of ​​repairing the Ligan because the cost of repairing the Ligan is likely to exceed the cost of rebuilding a destroyer.

This attack forced the USS Kaga aircraft carrier battle group, which was still performing combat missions, to retreat to the waters south of the Hidden Islands.

The biggest beneficiary is not South Korea, because the lack of an aircraft carrier battle group has not had a great impact on Japan. The Japanese Air Force, not the Japanese Navy, serves as the main force.

What really benefits are Germany, which is thousands of miles away, because the "Sun Yuanyi" class submarine that sneaked into the Japanese aircraft carrier battle group is the "Korean version" of the German 212 class submarine, and the heavy anti-ship torpedo that severely damaged 2 Japanese warships is the standard "Made in Germany". Although the Korean submarine failed to kill two aircraft carriers at a time like the Republic submarine in the Fourth India-Pakistan War, for Germany, which is eager to expand the international submarine market, the outstanding performance of the Korean submarine on the battlefield is the best promotion "advertising".

In 2022, the sales volume of German submarines reached 8~, twice that of 20211!

The sudden change of battle did not have much impact on the final result, but it only added a highlight to this war with huge differences in strength and little suspense.

damn it**
