The Pixiu did not launch an attack at Midway.

After more than a month of submarine life, Li Guang has grown greatly, and he has become very patient. After discovering the merchant ship, the Pixiu quietly followed behind and sailed west for a day. After a short period of contact, Li Guang discovered that the destroyer was known as a submarine killer, which naturally made sense.

Destroyers have not only speed, but also powerful armament. In fact, submarines do not have many means to deal with destroyers, especially when there are no torpedoes or missiles that can be launched vertically, and when submarines are discovered by destroyers, they are almost one-sidedly beaten.

Ten merchant ships formed a phalanx on the sea, while two escort destroyers protected them on both flanks. The distance between merchant ships on the sea at night is about a kilometer.

The Pixiu still did not attack that night, mainly because the sky was too good, and the moonlight illuminated the sea clearly. After all, this place is only more than 100 nautical miles away from Midway, and if the little devil sends out fighters, it will still pose some threat to the Pixiu.

waited until the next night, and finally waited for a once-in-a-lifetime opportunity. The moon is dark and windy again in the Pacific Ocean, which is a good opportunity to kill people and set fires. Li Guangxi immediately ordered the Pixiu to prepare for battle.

At this time, the first mate Ren Tianyang proposed a tactic. He advised the Pixiu to rush to the front of the fleet, then dive and wait for the devil to arrive. In this way, the Pixiu was able to float in the middle of the phalanx of the merchant ships, and it could not only launch an attack smoothly, but also avoid the blows of the destroyers' guns. If the opportunity is good, you can also sneak attack the destroyer.

Li Guang was very pleased that officers who were willing to use their brains to fight were very important to the growth of the Naval Resistance Army. There is a serious shortage of naval officers in the Maritime Resistance Army, and even a layman like Li Guang is really the commander who is most familiar with submarines in the Naval Resistance Army. In fact, Li Guang had only watched a few movies about submarine warfare.

Later, Ren Tianyang's tactics were carried forward by the submarine of the Maritime Resistance Army, more than a year before the Germans adopted this submarine tactic. And this is not the plagiarism of Li Guang, a traverser, but the creation of a petty officer of the Chinese Navy. China has never lacked soldiers who have created a surname mentality, and the key is that there is no suitable stage for them to play.

Ren Tianyang was also poached by Huang Zhonghua from the Mawei Naval Academy, and he was different from the other two naval resistance officers from the Mawei Naval Academy. The other two were not able to graduate for various reasons, but Ren Tianyang was in school, when he was invaded by the Kou, and with the belief of killing the enemy and serving the country, he resolutely left school to join Li Guang's team. Ren Tianyang is now twenty-four years old, has been in the Mawei Naval Academy for seven years, and is quite proficient in naval tactics.

Due to the lack of funds for the Chinese Navy, it is impossible to equip a large number of warships, so Ren Tianyang paid special attention to the combat skills of small warships in school. However, because the Mawei Naval School does not have submarines, there is no tactical teaching about submarines. Ren Tianyang really came into contact with submarines only in the Naval Resistance Army, and his performance made Li Guang appreciate it very much.

The quality of education at Mawei Naval School is really good, and the three people who were dug up from there are now the backbone of the Naval Resistance Army, two of them are all serving on the Pixiu, one is Quan Yonghai, the squad leader of the torpedo squad, and the other is Ren Tianyang, the first officer.

At midnight, the Pixiu quietly dived into the deep waters, like a swarthy shark, waiting for the arrival of the merchant ship.

Under the water at a depth of ten meters, Ji Kelian listened attentively to the movements on the sea. The noise formed by a dozen ships was quite large, and at a distance of ten nautical miles, Ji Kelian could hear it.

Subsequently, the Pixiu continued to adjust at low speed, and before the merchant ships arrived, it steadily occupied the center of the merchant ship phalanx.

In the dark sea, in the middle of ten swarthy merchant ships, a periscope appeared. The situation seemed strange and inexplicable, as if a tiger had suddenly appeared in the flock.

The phalanx on the sea was slightly different from that during the day, and although the two destroyers were still protected on the two wings, the distance was noticeably widened. It is a full two nautical miles from the Merchant Marine Center.

Li Guang couldn't figure out what tricks the devil was playing. But at this distance, the torpedo range on the Pixiu was not enough. It is not difficult to sneak attack the merchant ship itself, the difficulty lies in how to take out two destroyers in the first place.

According to the pre-war plan, at least one destroyer should be killed at the first time of the war, and of course it would be more ideal to be able to take out two.

The situation now is that both destroyers are on the verge of torpedo range, and if they attack rashly, I am afraid that it will be difficult for one to hit.

Faced with the new situation on the battlefield, Li Guang's mind was racing rapidly. It should be said that Li Guang has really used his brains during this period of time, and he has greatly improved his submarine tactics, but after all, he cannot be compared with a formal submarine command officer.

Do you make a detour to the periphery of the merchant ship and attack the destroyer or kill the merchant ship first? This is an issue that Li Guang must make a decision on immediately.

In the few minutes that Li Guang was embarrassed, God seemed to be against Li Guang, the wind had just been blowing for a few hours, and now the sea was calm and calm, and the moonlight was like water.

Ren Tianyang immediately reported the situation to Li Guang.

Li Guang knew that at a distance of only a few hundred meters, it was entirely possible for a merchant ship to see the periscope of the Pixiu. Time did not allow him to hesitate. So immediately the order was given to start attacking merchant ships.

Li Guang did not know that the repairs to the Pixiu did not only come from the two destroyers. Even merchant ships are a threat. The greater threat was behind the flotilla, less than twenty nautical miles, and Yamaguchi Tawen was pursuing it with a special cruiser and a destroyer.

After a few days of thinking, Yamaguchi Tawen made a very strict battle plan. Yamaguchi Tashi had no basis and intuitively felt that the submarine was still peeping. Li Guang did not launch an attack yesterday, which surprised Yamaguchi Tawen, but even so he did not give up tracking. The previous moon was dark and windy and caused a lot of disturbance to Yamaguchi's plans, but at this moment, the sea and sky were clear again, and Yamaguchi's mood was relaxed.

Ji Keliang made a slight mistake this time, he actually heard the difference between the noise of the two destroyers, but he didn't pay much attention to it.

In fact, Ji Keliang reported the difference between the voices of the two destroyers to Li Guang, and Li Guang would turn a blind eye and listen to it. He didn't know the difference in equipment between the destroyers, but he saw that the two destroyers were about the same size.

So far, the Naval Resistance Force does not have a complete intelligence network, and it does not even know what types of destroyers the Navy has. Most of the captured merchant mariners still had an impression of the destroyers of the 20s, such as the Fengfeng class, but they did not know anything about the cutting-edge destroyers of the Shomoto Navy. And Li Guang didn't even know anything about the tonnage, firepower, and other parameters of the destroyers of the Navy.

As a matter of fact, he himself has done quite well in keeping this information secret, not to mention Li Guang, and even the United States does not know much about the situation of his armaments. This era is not the Internet era of later generations, and it is actually difficult to gather this information.

This is a Chunchun-class destroyer, different from the Fengfeng-class destroyer, with strong anti-submarine capabilities and powerful torpedo attack power, this destroyer's naval guns are not very powerful, but it is a torpedo as the main attack weapon. With a displacement of 1,750 tons, only one two-mounted 127 naval gun and one single-mounted 127mm naval gun were installed. But three twin 610mm torpedo tubes were installed. That is, six torpedoes can be fired at the same time.

This destroyer is a cutting-edge destroyer in the Navy, and it has only been built for three or four years and is in very good condition. Only six such warships were built, four of which belonged to the First Mine Squadron of the First Fleet. The equipment of the Fifth Fleet was indeed pitiful enough, and as a result, at the request of the commander of the Fifth Fleet, Nobutake Kondo, the remaining two ships were transferred to the Fifth Fleet.

The biggest threat to the Pixiu was neither its guns nor its torpedoes, but the fact that the battleship was equipped with active sonar, not just a listening device.

He said that he called the passive sonar as a listening machine, and the active sonar as a detector. Sonar has been invented for a long time, but it has not been taken seriously by the Yamaguchi Navy, but there are not many officers in the Navy, like Yamaguchi Tawen, who pay attention to new technologies and new tactics, and under the impetus of these people, sonar has just begun to be used on destroyers.

The listening machine has a wide detection range and many sound directions, so it can be found, but it cannot grasp the target distance.

In the case of a detector, it can measure the distance, but the search object is narrow, and there are many restrictions on its use.

Therefore, using a listening device to alert the surrounding submarines, listening clearly, measuring the distance with a detector, and then attacking, is the most advanced tactic in the world.

And this is one of the bases for Yamaguchi's plan.

Yamaguchi is smart enough and has new ideas. However, Li Guang does not need to bother with his brain at all, in the thinking of a person in the 21 st century, submarines need sonar, radar, and other means are the most basic common sense, so many military experts have just come into contact with these things, and Li Guang has not hesitated to adopt them.

Regarding the surname of sonar, Li Guang doesn't know how far his technology has come. But he knew very well that the German sonar he was using was capable of it. To put it simply, the earpiece is still usable, and it can play a huge role in the hands of a master like Ji Keliang. But the surname of active sonar can be simply a mess, and the error is extremely large.

And the Ninety-Three Type Detector that Yamaguchi Duowen is relying on now has a very bad surname, and it is not much better than the German sonar that Li Guang bought more than a year ago.

It is possible to measure whether there are obstacles within two kilometers, but the distance is confused, and it is normal for an error of one or two kilometers to be 100 meters. And this active sonar has a more fatal flaw, in fact, the same is true of the German one. For moving targets, the ranging is even more inaccurate. Li Guang had done experiments, and for an object that was moving at a speed of more than 20 knots at a distance of 1,000 meters, the signal was simply chaotic and the distance could not be measured.

The battle had not yet begun, and Li Guang actually lost tactically to Yamaguchi. One potential winner is that Yamaguchi is not skilled enough in weaponry, and he is actually groping for experimenting with tactics.
