Just a few days after the appraisal meeting of Duke's new project results, an unexpected incident broke the tense situation in East Asia. Near the Diao Island in the East China Sea, a Song-class submarine of the PLA and a Canglong-class submarine of the Japanese pirates collided violently. Due to the sudden incident, the PLA submarine captain had only time to send some interrupted information about the collision incident, and the submarine sank on the bottom of the sea, and all the officers and soldiers of the ship died heroically.

Afterwards, the Japanese Pirates issued a statement saying that this was an "unexpected incident" and expressed regret for the death of the Chinese submarine. At the same time, the Canglong class who had the accident publicly announced that the Canglong class would return to the base for "repair", and proudly declared his attitude towards the winner in this incident.

According to the opinions of the Chief of Staff, the US military delivered the three squadrons of F-35 as Japanese pirate procurement list goods to Japanese pirates. Since the Japanese pirates' self-defense team felt that their strength had increased greatly. Although the US military was suspected of using Japanese pirates as guns at this time, the Japanese pirates had no choice but to accept it happily and handed over a large sum of dollars to the US military. For the US military, this did not damage their air strength in East Asia at all. Anyway, the Japanese pirates' air force was also under their command and could easily get the money. This kind of transaction is really profitable and will not lose money.

However, the Japanese pirates were greatly encouraged, especially the arrival of a large number of US Navy and Air Force, which made the Japanese pirates' military full of confidence, which was more than 10,000 words from Secretary Burns.

Against this background, the Japanese Navy and Air Force's activities in the East China Sea are becoming more and more frequent, and the Diaoyu Islands are even more frequent. Although collision incidents are a bit accidental, they are also the inevitable result of frequent activities of the navies on both sides in this area.

Regarding the Japanese pirates' statements, China carefully analyzed the information returned by the PLA submarine captain at that time to infer and simulate it. Combined with the performance of the submarines of both sides, it was found that this incident was highly likely to be a deliberate collision of the Japanese submarine!

Because of the performance of the Canglong-class sonar system, even if the PLA's Song-class submarine has undergone nuclear power transformation, greatly reducing the noise of the propulsion system, the noise emitted from hulls and other unchangeable places is still quite large. It can avoid anti-submarine searches of the US aircraft carrier fleet and rely on ground information for maneuvering, rather than relying on its own discovery capabilities.

However, the Canglong class is different. The sonar system of this latest generation of Japanese pirates is quite complete. It consists of the cylindrical sonar on the head of the submarine, the reconnaissance sonar on the upper part of the bow, the conformal sonar array on the side of the hull, and the towed sonar released from the tail of the boat. The detection distance of passive target search can reach 5 to 15 nautical miles, but the stern of the ship is equipped with towed low-frequency array sonar, which can be detected at most 100 nautical miles under active conditions.

The sonar system of the Song-class submarine is only one set of mid-frequency active passive search and attack ship shell sonar installed at the bow and another set of passive low-frequency search sonar installed on the side. It is not yet equipped with towed passive sonar. In this way, when the two meet, the discovery ability of the Song-class submarine is obviously far inferior to that of the Canglong class of the Japanese pirates.

In this case, if the Japanese pirate Canglong class, with a body of more than 4,000 tons, intentionally collided with a Song-class submarine with only 2,000 tons, it would be a big loss. The People's Liberation Army's naval intelligence analysts carefully studied the information sent back by the captain of the Song-class submarine and found that the part that was hit by the Song-class submarine during the collision was its most fatal. Moreover, from the perspective of the orientation, the Japanese pirate Canglong class submarine was almost at the best offensive position at the time, and the collision damage area was also the place with the least impact, which made analysts believe that the Japanese pirates had great suspicion that they did this on purpose.

It’s just that this silly loss, the People’s Liberation Army was unable to seek justice from open channels, but this incident poured a basin of cold water on the upper level of the military in time, realizing that at sea, our strength is actually far inferior to the alliance between the Japanese pirates and the US military. Especially big guys like submarines have not built many new products in recent years, just a few. The power improvement of old submarines has only solved some of the problems. Due to the difficulties of underwater transmission, the joint combat system cannot achieve seamless connection with land and air. Although Duke’s DSM is now studying underwater remote transmission technology, in this relatively unfamiliar new field, even if Duke is paying attention at any time, the results are not released so quickly.

Fortunately, a Navy research institute's sonar has just achieved a breakthrough. I felt the severe assembly and the navy immediately asked the institute to immediately carry out large-scale transformation of the navy's sonar system, and upgrade all the main destroyers and submarines. This sudden situation greatly affected the development rhythm of the military, and the US military's gathering and deployment of troops in East Asia made the military feel tremendous pressure.

Although the Battle of India-Bahra Kashmir greatly enhanced everyone's confidence, the South China Sea submarine penetration has further strengthened this confidence, but the top leaders strategically underestimated the Americans' determination to maintain their world hegemony.

It is in the current situation that the sudden explosion of submarine collision incident has to make the military extremely vigilant.

"This matter cannot be over. We must retaliate to defeat the arrogance of the Japanese pirates," Mr. Liu took the analysis report of the naval intelligence analysts and said to General Staff General Yang Hongsheng, "It's just that there are Americans here. This level requires the General Staff to consider it well, so that the Japanese pirates will suffer a loss."

"Vice Chairman Liu, the General Staff is following up on this matter and formulating corresponding countermeasures," Yang Hongsheng replied bitterly in the face of Mr. Liu's request, "But now it seems that the submarine may not be able to cope with the joint attacks between the Japanese pirates and the Americans for the time being.

According to reliable information, the US military has mobilized at least 20 nuclear submarines to enter East Asia. In addition, the so-called retired submarines have been sealed for many years in the past two years and have re-entered the active service. They have quickly expanded their submarine troops to more than 60, and the total number of submarines has exceeded 80, which has greatly exceeded our submarines in number.

And in terms of quality, there are too few advanced submarines that we have directly competed with the US nuclear submarines, with less than 10 ships in 095,096. Although there are 12 ships and 6 Kilo-classes in 041, even if the nuclear power drive is transformed and upgraded, the displacement, weapon equipment, combat systems cannot be compared with the US Los Angeles class, let alone the Seawolf class and Ohio class.

After improving the sonar system, we may be able to compete with the conventional Canglong-class and "Qianchao" diesel-electric submarines of the Japanese pirates, but our number is less than that of the opponent. The 20 039s are just equivalent to the "Chunchao"-class submarines of the Japanese pirates. The technology gap between other old-fashioned submarines is too big, and we can basically not fight against the "Chunchao" and "Xichao"-class submarines of the Japanese pirates alone. In other words, the number of submarines we have to compete with our opponents is almost half the difference."

"But we can't sit idly by and make the Japanese pirates even more arrogant. In terms of anti-submarine, have we made new breakthroughs?" Mr. Liu frowned and said. This number gap cannot be caught up in one day, and Mr. Liu can only hope to make up for it by technological progress.

"It will take time for technological breakthroughs to transform and upgrade the navy. The navy estimates that it will take at least three months to upgrade the sonar system of the Navy's existing main ships. Even if the submarine force is upgraded first, it will take at least one month." General Manager Yang smiled bitterly, "Over 40 of our main submarines need to fully upgrade the sonar system, and one month is already very tight."

Hearing this, Mr. Liu couldn't help but feel silent.
