Just a few days after the appraisal of the results of Duke's new project, an unexpected event broke the tension in East Asia. In the vicinity of Diaoyu Island in the East China Sea, a Song-class submarine of the People's Liberation Army (PLA) and a Canglong-class submarine of the Wakou had a violent collision, and because of the suddenness of the incident, the commander of the PLA submarine only had time to send some intermittent information about the collision incident, and the submarine sank to the bottom of the sea, and all the officers and men of the ship were martyred.

Afterwards, he issued a statement saying that it was an "accident" and expressed regret over the death of the Chinese submarine, and at the same time publicly announced that the Canglong-class class that had the accident would return to the base for "repair", and proudly declared himself a victor in this incident.

According to the opinion of the Chief of Staff of the Army, the U.S. military delivered three squadrons of F-35 to the U.S. Army as a goods on the U.S. Kor's procurement list, and the U.S. Self-Defense Forces felt that their strength had greatly increased, and although the U.S. military was suspected of using the U.S. Woko as a gun at this time, the U.S. military had no choice but to happily accept it and hand over a large sum of dollars to the U.S. military. This kind of trading is really a sure deal.

In particular, the arrival of a large number of US naval and air forces has made the Japanese military full of confidence, which is more than Secretary of State Burns can say 10,000 words.

Against this background, the activities of the Japanese Navy and Air Force in the East China Sea have become increasingly frequent, and the vicinity of the Diaoyu Islands is a place where they frequently come and go, and although the collision incident is somewhat accidental, it is also the inevitable result of the frequent activities of the two navies in this area.

After carefully analyzing the information returned by the captain of the PLA submarine at that time, the Chinese side inferred and simulated it, combined with the performance of the submarines of both sides, and found that this incident was very likely to be a deliberate collision between the Japanese submarines!

Because with the performance of the Canglong-class sonar system, even if the PLA's Song-class submarine has undergone nuclear power transformation, which has greatly reduced the noise of the propulsion system, the noise emitted by the hull and other unchangeable places is still not small, and it can evade the anti-submarine search of the US aircraft carrier fleet, relying on ground information to maneuver and evade, rather than relying on its own discovery ability.

However, the Canglong class is different, this kind of submarine of the latest generation of Japanese Koukou, the sonar system is quite perfect, consisting of the cylindrical sonar at the bow of the submarine, the reconnaissance sonar on the upper part of the bow, the conformal sonar base array on the side of the hull and the towed sonar released from the stern, etc., the detection distance of passive target search can reach 5 to 15 nautical miles, but its stern is equipped with a towed low-frequency array sonar, which can detect about 100 nautical miles at a maximum distance under active conditions.

However, the sonar system of the Song-class submarine is only one set of medium-frequency active and passive search and attack hull sonar installed in the bow of the boat and one set of passive low-frequency search sonar installed on the broadside, and it is not equipped with towed passive sonar.

In this case, if the body of more than 4,000 tons of the Canglong-class deliberately collided with the Song-class submarine of only 2,000 tons, it is obvious that the latter will suffer greatly, the PLA naval intelligence analysts carefully studied the information sent back by the captain of the Song-class submarine, and found that the part of the Song-class that was hit at the time of the collision was its most deadly, and from the perspective of the direction, the Canglong-class submarine of the Wako was almost in the best offensive position at that time, and the collision damage was also the least impactful. This has led analysts to believe that there is a strong suspicion that the pirates did this on purpose.

It's just that this dumb loss to the PLA side can't get justice from open channels, but this incident poured a basin of cold water on the military upper-level bosses in time, realizing that at sea, our strength is actually far inferior to the alliance between the Japanese and the US military, especially the big guys like submarines, in recent years, there are not many new ones, just a few, and the transformation of old submarines, the improvement in power only solves part of the problem, and the joint combat system cannot achieve the same seamless connection as land and air due to the difficulty of underwater transmission. Although Duke's DSM is now researching underwater long-range transmission technology, in this relatively unfamiliar new field, even if Duke is paying attention to it at any time, the results are not so fast.

Fortunately, a certain naval research institute has just made a breakthrough in sonar, and the navy, which is deeply aware of the grim form at sea, immediately demanded that the research institute immediately carry out a large-scale transformation of the navy's sonar system, and upgrade all the main destroyers and submarines. This sudden situation has greatly affected the pace of military development, and the military has felt tremendous pressure on the military in the build-up and deployment of troops in East Asia.

Although the battle between India and Pakistan in Kashmir has greatly strengthened everyone's self-confidence, and the submarine penetration in the South China Sea has strengthened this confidence a lot, the high-level still strategically underestimated the Yankees' determination to maintain their world hegemony.

It is precisely in the current situation that the submarine collision incident that suddenly broke out cannot but make the military extremely vigilant.

"This matter can't just end like this, we must take revenge in order to be able to hit the arrogance of the Japanese invaders," at the countermeasures meeting of the Central Military Commission, Mr. Liu took the analysis report of the naval intelligence analysts and said to Yang Hongsheng, the chief of the General Staff, "It's just that there are Yankees, and this degree requires the General Staff to consider it well, so that it is better to let the Japanese suffer a dumb loss." ”

"Vice Chairman Liu, the General Staff Department is following up on this matter and formulating corresponding countermeasures," Yang Hongsheng replied with some bitterness in the face of Old Man Liu's request, "It's just that now it seems that the submarine side may not be able to cope with the joint attack of the Japanese and Yankees for the time being."

According to reliable intelligence, the US military has mobilized at least 20 nuclear submarines into East Asia. In addition, in the past two years, the Japanese have re-added the so-called decommissioned submarines that have been mothballed for many years, and they have quickly expanded their submarine force to more than 60 submarines, bringing the total number of submarines to more than 80, which has greatly surpassed our submarines in number.

Moreover, in terms of quality, the number of advanced submarines that we have to directly compete with the US nuclear submarines is too small, less than 10 095 and 096 combined, and 041 although there are 12 plus 6 Kilo-class, but even if the nuclear power drive is upgraded and upgraded, it cannot be compared with the Los Angeles class of the US military in terms of displacement, weaponry, and combat system, let alone with the Seawolf class and the Ohio class.

After improving the sonar system, we may be able to compete with the conventional Canglong-class and "Qinchao"-class diesel-electric submarines, but we are fewer than our opponents. And the 20 039 are only comparable to the "Spring Tide" class submarines of the Japanese Invaders, and the technical gap between other old submarines is too great, and basically they cannot fight against the "Spring Tide" and "Xichao" classes of the Japanese Invaders alone, in other words, the number of submarines we have to compete with the opponent is almost half. ”

"But we can't sit idly by and make the Japanese even more arrogant, and in terms of anti-submarine, haven't we made a new breakthrough?" Old Man Liu frowned and said, this gap in quantity cannot be caught up one day, and Old Man Liu can only hope that technological progress will make up for it.

"It will take time for the Navy to make a breakthrough in technology, and it will take at least three months for the Navy to upgrade the sonar system of the Navy's existing capital ships, even if it is a priority to upgrade the submarine force, it will take at least one month or more." Chief Yang said with a wry smile, "More than 40 of our main submarines are going to comprehensively upgrade their sonar systems, and a month is already very tight. ”

Hearing this, Old Man Liu couldn't help but be silent.
