days, the tide of battle changed slightly.

The ROK Air Force adjusted its tactics and instead of continuing to attack the Japanese aircraft carrier battle group and the amphibious combat fleet, it dispatched a large number of fighter jets to launch missiles and drop long-range guided bombs at the Japanese troops on Dokdo in the airspace near Ulleungdo. The South Korean Navy dispatched 3~large transport ships to transport an artillery battalion equipped with long-range rocket artillery and tens of thousands of large-caliber long-range rockets to Ulleungdo to prepare for long-range artillery bombardment of Dokdo.

The tactic of "fighting cattle across the mountains" has paid off.

Because Ulleungdo is recognized as South Korean territory, if Japan bombs Ulleungdo or strikes South Korean combat planes flying over Ulleungdo, the United States will have a reason to enter the war, so Japan is very "restrained" and does not launch a counterattack, not even engaging the South Korean Air Force head-on.

This is also a very helpless tactic, and if there is another choice, South Korea will not do it.

According to Japan, South Korea has resorted to "vile" tactics, which justify South Korea's abandonment of the idea of "aggression" on Dokdo.

For the Japanese soldiers who landed on Dokdo, it was not a good day.

The bombing of the ROK Air Force was very frequent, and every few minutes a missile or bomb fell on Dokdo, causing the Japanese officers and men to be so frightened that they had to be ready to rush to the nearest air raid shelter at any time. From 16:30, South Korean artillery joined the battle, and at the first shelling dropped thousands of rockets on Dongdo (Dokdo has two main islands, east and west). Although more than half of the rockets landed on the sea, one Japanese soldier was still killed. Subsequently, several rockets fell every 1 minute, forcing the Japanese to speed up the digging of anti-aircraft bunkers.

When the war is fought, South Korea is in a dilemma.

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

Beat. You can't win. Don't fight. I can't give an account to the people.

Just when everyone thought the battle was settled. Nighttime. The situation took a sudden turn.

About a point. The aircraft carrier battle group "Akagi" (named "Akagi" and "Kaga" by Japanese aircraft carriers) in the northwest waters of the Oki Islands was attacked by a submarine. At least 1 heavy torpedo hit the "Akagi". Another 1 torpedo hit the air defense destroyer "Tone" less than 3 nautical miles from "Akagi". 2~ A fire ignited on the battleship lit up the night sky. It is clearly visible on the hidden islands tens of kilometers away.

Early morning of the 5th. South Korean President Park Tae-hyun personally announced. Navy submarines sink one Japanese aircraft carrier and one destroyer!

That same evening. Almost all Koreans have insomnia.

Until dawn. In just a few hours. Hundreds of thousands of people gathered outside the Cheong Wa Dae Presidential Palace. Koreans holding up the Korean flag and posters with presidential portraits and shouting slogans such as "Long live the Korean nation."

The reality is sure to disappoint all Koreans.

At 8 o'clock, Murakami announced at the Prime Minister's Office to Japanese reporters that the aircraft carrier "Akagi" and the destroyer "Tone" had been attacked by a submarine and had suffered heavy damage and were on their way back to the Tsuruga Naval Base.

Subsequently, Nippon television showed video footage of the two warships performing damage management and fire extinguishing.

Whether the South Koreans believe it or not, the aircraft carrier "Akagi" and the destroyer "Tone" did not sink, but only suffered heavy damage. The reconnaissance satellites of the Republic and the United States have successively taken pictures of warships returning home with injuries under the cover of other warships.

As if 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 an "oolong", but for this short-lived conflict, 2 heavily damaged warships have lost their combat capability, which is not much different from being sunk.

As it turned out later, both the "Akagi" and the "Tone" were almost sunk, and all that the South Korean submarine lacked was a little luck.

The mine-mining point of the "Akagi" was near the keel of No. 2311, that is, near the stern. Because of the design flaws, one torpedo almost blew off the propulsion shaft of the "Akagi". Although the "Akagi" was equipped with an auxiliary electric propulsion system, and even if all the main propulsion shafts were blown up, it could still return at a speed of 2 knots, but at that time there was a second torpedo being fired at the "Akagi", and finally almost hit the "Akagi", if the main propulsion shafts were all blown up, the "Akagi" would be doomed.

On the way back, the Akagi used an auxiliary electric propulsion system.

The problem of the "Akagi" is not only the propulsion system, because it has not designed an aircraft carrier for decades, and a large number of Japanese shipbuilding engineers and technicians have gone into exile during the turmoil, so when designing the "Akagi" site, Japan had to "start from scratch", except for electromagnetic catapults and other technologies imported from the United States, almost all the work had to be done from scratch.

Compared to ordinary warships, medium aircraft carriers with a displacement of many tons are much more complex.

When designing the watertight structure of the hull, Japanese engineers had to adopt many "clever methods" in order to control the displacement within the specified range. It turns out that in terms of the survivability of battleships, there is no "to find, you get what you pay for", and "cutting corners" will eventually have consequences.

Not to mention anything else, the United States has repeatedly proposed the development of small aircraft carriers for decades, but finally gave up, and is still building supercarriers with a displacement of more than 1 ton; While drastically reducing the size of aircraft carriers, the United States still has not reduced the displacement of aircraft carriers, in order to ensure the survivability of aircraft carriers to the greatest extent.

Due to the defects in the watertight structure, a few hours after the thunder, the water intake of the "Akagi" exceeded.

In order to reduce the weight, in addition to allowing all the carrier-based planes on the aircraft carrier to fly back to the land airfield, the captain of the "Akagi" also threw the ammunition on the aircraft carrier into the sea or transferred it to the supply ship that rushed to meet it, ordered the aviation kerosene tanks to be emptied, and did everything possible to increase the buoyancy of the aircraft carrier's reserves.

With the increase in the amount of water ingress in the tail section, in order to maintain longitudinal balance, the captain had to give the order to fill the ballast tanks at the front end.

In order to reduce the displacement, in addition to the pumping machines provided by the "Akagi", several pumping machines were sent from the battleships accompanying the escort to extract seawater from the hull using the electricity provided by other warships.

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

It can be said that the "Akagi" picked up a small life.

For a medium-sized aircraft carrier with a displacement of more than one ton, the survivability of the "Akagi" is really very bad. In the Fourth Indo-Pakistani War 7 years ago, the "performance" of the 2~medium aircraft carriers of the Indian Navy far exceeded that of the "Akagi" and was not sunk by 1 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 Tsuruga Naval Base, the Akagi overhaul work took 23 months, far exceeding expectations of eight months. The cost of the entire overhaul amounted to 65 percent of the construction cost of the "Akagi", which was not much less than the construction of a new aircraft carrier. Taking this opportunity, the Japanese Navy carried out a comprehensive improvement of the "Akagi", the main thing is to increase the survivability of the aircraft carrier. After completing the improvement, the standard displacement of the "Akagi" 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 put forward a plan for the construction of large aircraft carriers at the end of the year.

Because of the need to build a large aircraft carrier as soon as possible, the "Kaga" was not completely improved like the "Akagi".

The situation with the destroyer "Ligen" was even worse. The point of detonation of the heavy torpedo was still near the stern, and it blew up the 2 ~ main propulsion shaft. Fortunately, the "Tone" was fired at a torpedo that "missed" the "Akagi" during the attack, and no second torpedo threatened the destroyer "Tone".

It can be said that the survival of the "Rigen" is not only lucky, but also miraculous.

As a destroyer with a standard displacement of only more than 6,000 tons, it has to be said to be a miracle that it can withstand the direct attack of 1 heavy anti-ship torpedo.

Under normal circumstances, a heavy torpedo weighing more than 250 kg (the charge is about half the weight of the mine head, but the torpedo uses high-energy explosives, and the explosion power far exceeds that of ordinary explosives), which is enough to sink a 10,000-ton warship if it hits the keel of the ship.

The reason why the "Ligen" did not sink was that the hit point of the torpedo was too far back, and above the explosion point was the propulsion system that was heavily protected. If the point of the explosion had been moved forward by 50 meters, the "Rigen" would most likely have been blown in two on the spot, and there would have been no chance to struggle.

By the time we returned to Tsuruga Naval Base, the stern of the Tone had been submerged in the sea.

After a month-long thorough inspection and evaluation, Japan finally abandoned the idea of repairing the Tone, as the cost of repairing the Tone was likely to exceed the cost of rebuilding a destroyer.

This attack forced the "Kaga" aircraft carrier battle group, which was still on combat duty, to withdraw to the waters south of the hidden islands.

The biggest beneficiary is not South Korea, because the impact on Japan from one less aircraft carrier battle group is not very great, and it is the Japanese Air Force, not the Japanese Navy, that serves as the main force.

The real benefit was Germany, which was thousands of miles away, because the "Sun Yuanyi" class submarine that attacked the Japanese aircraft carrier battle group was the "Korean version" of Germany's 212-class submarine, and the heavy anti-ship torpedo that heavily damaged the 2 Japanese battleship was a standard "German-made" one. Although the South Korean submarine failed to kill two aircraft carriers at a time like the Republic submarine in the Fourth Indo-Pakistani War, for Germany, which was eager to expand the international submarine market, the outstanding performance of the South Korean submarine on the battlefield was the best sales "advertisement".

In 2022, the sales of submarines in Germany will reach 8~, which is twice as much as in 20211!

The sudden turn of the tide of the battle did not have much impact on the final outcome, but only added an interesting point to this war with a huge disparity in strength and little suspense.

Damn it**

During the closure period, every half an hour, the flickering brothers went crazy together, so that everyone was happy!
