The reaction of the opposing warships was also within Deng Jieqian's expectations, although the amount of depth charges was a little larger, in Deng Jieqian's plan, the 21 submarines responsible for the first wave of attacks were the main force of the next attack ship group, not the main force of the attack on the escort warships, and the first wave of disintegration of the remaining targets would be handed over to the remaining submarines to complete, and these 21 ships only had to wait for the signal, and when most of the escort fleet was killed, they would be put into the attack on the merchant ships of the ship group. Now it's just a matter of waiting patiently, as long as you protect your own safety and give the Entente a final blow when the opportunity comes.

In itself, even if the Qin-class submarine runs at high speed, the decibels are outside the detection range of the sonar, so the speed of the ship is reduced, and the deliberate run to the bottom of the merchant ship is even more confusing, the sonar has lost the possibility of discovering them, when countless depth charges are dropped, the result is already doomed, no matter how many depth charges they put in, it will not produce any effect.

In the sound of the explosion, thousands of depth charges blew up countless fish, and also shook the entire sea surface, in such a shock, Deng Jieqian led the remaining submarines, is using periscopes, to do the final preparations before the attack, the first wave killed 8 ships, 2 light cruisers, 6 destroyers, this is the main target, and two destroyers were traumatized. There were 2 light cruisers and 6 destroyers left, which were a threat to the submarines, and the 2 destroyers that were damaged in the first wave were already somewhat unable to support them at this time, and not only broke away from the depth charge delivery team, but also began to manage the damage.

Among the warships that the Entente also had combat effectiveness, 2 light cruisers, the threat to submarines was not as great as the rest, and he was an old-fashioned light cruiser. It is for the decisive battle at sea, that is, the artillery type light cruise, not the anti-submarine type light patrol that was born after the First World War, and this kind of light patrol is quite weak because of the inherent weakness of the design, even if there is a depth charge projector. Two or three is too much, and it is impossible to get as many as seven or eight at once like a destroyer, so such a light patrol, among all the targets, can also be postponed. In other words, at least 4 destroyers, at most 6, such a difficulty is the same as before. When it comes to the ship group, it is greatly reduced.

Of course, Deng Jieqian's current power is also less, and the 21 submarines in the first wave cannot continue for the time being, but fortunately, he still has 10 at hand, when the destroyer is frantically dropping depth charges. Deng Jieqian ordered 10 submarines by radio. Gradually approaching them, this time, because they were still crazy, the submarine would not come close to within 1 km of the destroyer, and this was the first time that the submarine attacked more than 1 km away, just to be on the safe side. They chose to attack 4 of them, which were also among the destroyers, the ones that were not damaged, and the rest were put aside.

The submarine was a kilometer away, and firing a torpedo was the first time in real combat. However, on the training ground, on the way to Europe, the submarine attacked more than once at a place of 1 kilometer, or even more than 2 kilometers, and the flying torpedo was not only extremely fast, but even in terms of range, it also exceeded the range of most torpedoes, with a total range of more than 3.5 kilometers. 1 km is only in the range of 3.5 km, a very inconspicuous front, in this regard, the flying torpedo is stronger than other torpedoes, between one km and two km, is also the range of most submarine attacks.

At this moment, of course, it is impossible to adjust as before the war, only to maintain a general directionality, the nearest is about 1000 meters, more than 900 meters, and the farthest is not more than 1250 meters, and then 10 submarines, aimed at 4 destroyers, in the first time, issued 30 torpedoes, aimed at the four destroyers who are frantically throwing depth charges, they are also this escort fleet, there is still the last, complete force left.

Because of the sudden attack, the damaged destroyers are just saving themselves, those who have nothing to do, naturally gather together, these four destroyers are acting collectively, which gives the submarines a chance, the four destroyers that are separated are much more difficult to deal with than the destroyers that are gathered together.

This may be a mistake, but it is not, from the beginning of the warship into modernization, the cluster effect quickly appeared, the density and destructive power of the 4 destroyers collectively dropped depth charges, far stronger than the 4 individual drops, they did not expect that the submarine is absolutely weak for the destroyer, after the completion of the sneak attack, not only did not take the initiative to retreat, but took the initiative to catch up.

The submarine is the most difficult to find a destroyer, and the torpedo has a clear waterline, which can be easily avoided as long as the destroyer is running at high speed, even if the torpedo can reach a speed of 65 knots. At this time, the power of the flying torpedo was shown, even if the torpedo was issued from a kilometer away, even if it was under the full alert of the opposing destroyer, except for the sonar to find the sound, there was nothing left, the torpedo in the action of 2-5 meters would not produce huge bubbles by itself, and the propeller driven by the electric motor also brought the knowledge of fluid mechanics to the extreme, as much as possible to be hidden, at least, above the water, it was difficult to see the trajectory of the torpedo attack.

A distance of 1 kilometer, for a torpedo of 65 knots, is only a 0.6-minute range, converted into seconds, it is only 36 seconds, perhaps for a 100-meter athlete, 36 seconds, is more than three 100-meter sprints, and even when the destroyer accelerates to the maximum, one hundredth of an hour, it may drive 0.36 nautical miles, which is five or six hundred meters, which should be enough to escape.

Unfortunately, this is completely useless, because the destroyer realizes that he may be attacked, but he doesn't know, where to hide, the sound of the torpedo propeller, and the sound of the propeller of the battleship, these are two completely different sounds, sonars often train the sound of the submarine's propeller, and they are not familiar with torpedoes, which is also the fundamental reason for the strong results of torpedoes before, and the sonar can hear the approximate location of the submarine according to the sonar and the sound of the propeller, even if he hears the sound of the torpedo, he does not know where the torpedo is, which greatly enhances the effect of torpedo firing.

4 destroyers stopped throwing depth charges and began to evade, but unfortunately 30 torpedoes, only about 36 seconds of sailing time, the destroyer from hearing the sound, to the captain stopped throwing depth charges, entered the evasion state, at least ten seconds of time was wasted in the middle, the rest of the time did not have the correct reaction at all, according to the habit to do the evasion, but the effect was not good, 30 torpedoes, all the positions have been sealed, 30 torpedoes against 4, the situation of these 4 ships, It was much more dangerous than the previous 10 ships, with dense torpedoes on all sides.

The combat quality of the British Navy is still more than a step higher than that of the US military, and it is in absolute danger, and the sonar officer did not judge the distance and direction of the torpedo, and the destroyer still did evasion, if it was not enough torpedoes for the four destroyers, they really ran away, just like that, 3 destroyers were torpedoed in the body, and the other was torpedoed at close range, directly injuring the bow.

3 heavy damage, 1 lightly injured, the quality of the British Navy is enough to make Deng Jieqian marvel, but unfortunately it is useless, the battle has reached this extent, the dust has settled, the powerful power of the flying fish torpedo is not something that any destroyer can withstand, the two destroyers with the wounded crazy depth charges before, but they are just puffing up the courage and driving at high speed, but it is not conducive to their management of damage, especially the crazy depth charges, which occupy the manpower, these two destroyers, the speed has been reduced by about half, and there are obvious signs of tilting, Now that he is in danger, he will not be able to complete the basic tasks, and he will not even be able to protect himself.

Of the 18 warships, 2 mounted cruisers have no submarine attack capability, and 2 light cruisers have not been damaged so far, their attack power is only a quarter of that of ordinary destroyers, and the remaining battleships are either heavily damaged or sinking, and have basically lost their ability to strike submarines.

This situation, not only the British army knew, Deng Jieqian also saw clearly, leaving a few submarines, after continuing to attack the destroyers that still had the ability to resist, the rest began to bloom in all directions, encircling and suppressing the remaining merchant fleet, by the way, attacking the undamaged patrol and two light patrols, this is the biggest big fish, take this, to be able to declare this raid, a complete victory, the entire sea, and a new round of attacks began, and it was a mess.

From the beginning to now, it is only a few minutes, it is too late to say that it is fast, everything is like a kaleidoscope, until now, the British army responsible for escorting this huge group of ships, there is no way to distinguish where the opponent is, where this submarine and torpedo came from, but according to the previous naval experience, the Supreme Commander is very clear that he is afraid that he does not threaten any enemy submarines, and those submarines are like assassins hiding in the shadows, After launching a surprise attack, they hid from others, so that they could not tell where the other party was.

This is the most bizarre and dangerous situation that all British officers have encountered since they were engaged in the navy, and they can't care so much at this moment, and they must make a decision as soon as possible, otherwise, the entire ship group will usher in a catastrophe, especially the two loading cruisers, which are 15,000 tons of big guys, but such a main battleship has little effect on dealing with submarines.
