The sailors on the escort ships are also very lax, in their opinion, the stormy ocean is the inner lake of the Axis countries, no matter how bold the NATO submarines are, they dare not come here to spread wild, not to mention that every day the seaplanes of the Axis countries patrol back and forth, those submarines will be discovered as long as the snorkel is exposed to the sea to recharge, and how to attack them.

Unaware of the approaching danger of the road, the merchant fleet was still moving in loose formation, and there were no less than ten submarines lurking around them. "Damn sonar, I can't hear any movement." The sonar on one of the destroyers grumbled by putting their headphones on the machine.

His companion laughed: "If you can't hear the best news, don't you still want the submarines of the Chinese Empire to find you?" ”

The sonar soldier said: "I heard that the current sonar of the Chinese Empire is quite powerful, and our submarines can't hide at all. ”

The companion said: "I also heard that now the Admiralty has banned all submarines from going to sea, and I heard that experts are working on solutions. ”

The sonar soldier sighed and said: "This kind of problem is so easy to solve, if you don't want to be found by other people's sonar, you have to reduce the noise, but the submarine is like that, no matter how it changes, the noise is difficult to reduce, unless a new submarine is built, it will not be effective." ”

His companion said suspiciously: "You said that people's sonar is so powerful, will they be able to hear us?" ”

The sonar soldier laughed and scolded: "Don't scare yourself, where is there such a god in sonar." ”

The two submariners who were chatting didn't know what to do, and while they were chatting, Liu Yujie and his companions had already gathered around the fleet, preparing for an attack by Lu.

"Everyone is ready, let's start attacking." When the submarines of the Chinese Empire fought together, they were accustomed to letting the captain with the highest side number command, and among the ten submarines gathered this time, Liu Yujie's submarine number was the most advanced.

"Attention to the torpedo room, torpedo tubes No. 1, No. 2 are prepared, with wake self-guided torpedoes." Liu Yujie used sonar to observe the enemy fleet outside, and at the same time issued an attack order.

"Yes, torpedo tubes No. 1 and No. 2 are ready." The torpedo room quickly sent back the message.

"Launch now." With Liu Yujie's order, the two torpedoes came out of the torpedo tubes and rowed towards their targets.

The torpedoes in service in the Chinese Empire are all guided torpedoes, and they are divided into magnetic torpedoes, wake self-guided torpedoes, sonar guided torpedoes, and wire-controlled torpedoes according to different guidance methods. These torpedoes are capable of finding targets on their own, and even if they cannot directly hit the target, they will explode under or near the target, destroying them with a shock wave, and the hit rate is very high.

As a result, the Imperial submarine forces were no longer like their predecessors, firing several torpedoes in order to hit a target, which greatly saved torpedoes and increased the duration of the submarines' operations.

It was too late to say that it was too late, and the two wake self-guided torpedoes had already caught up with two 10,000-ton freighters. The thermodynamic torpedoes produced by the Chinese Empire could not see any obvious wake on the water, and they quietly followed their respective targets, and with two loud bangs, the tail of two 10,000-ton freighters was hit.

These heavy torpedo charges are so heavy that even if a 10,000-ton cruiser with heavy armor and subdivided watertight compartments is one by one, it will only sink, not to mention these fragile cargo ships, these two ships quickly sank without suspense.

The sonar soldier, who was still chatting just now, was already a little drowsy with the headphones, and the huge explosion shock wave made a piercing sound in the headphones, almost deafening the sonar soldier, and he immediately jumped up: "Damn, what happened." ”

The drowsy companions on the side were also awakened by the sound of explosions, and before they could confirm it, a continuous explosion had already been heard, and now there was no need to confirm it, it was everyone who understood that they had been attacked.

The continuous sound of explosions has rendered the Bostonians' old-fashioned sonar, which cannot shield the clutter from the noise, simply does not work properly in the explosion, and now the sailors on the destroyers can only rely on searchlights and binoculars to detect enemy submarines.

The awakened sailors ran to the deck, they were well-trained to turn on the searchlights, and carefully searched the sea, but the thermodynamic torpedoes with no obvious wake were not at all what they could find, not to mention that those torpedoes could turn on their own, which made the Boston destroyer a little overwhelmed when it encountered this situation for the first time.

The inactive destroyers blindly searched for submarines, while the submarines of the Chinese Empire hunted unscrupulously. It was a one-sided slaughter, and the sluggish freighters, laden with cargo, had no hope of escaping, and they could only watch as torpedoes came from all directions and sank them one by one.

It only took more than half an hour's work for all the freighters to sink, and in addition to the burning wreckage on the sea, only four inactive destroyers were left to ram around, aimlessly searching for nearby submarines.

"Boss, there are a few little guys, can we fight?" The first mate was already addicted, he rubbed his hands excitedly and asked about Liu Yujie.

Liu Yujie pouted and said: "With such a small tonnage destroyer, it is a waste of torpedoes to fight, so let's save some to hit the transport ship, that guy has a large tonnage." As soon as Liu Yujie's words fell, after a few loud noises, the four destroyers were also blown into two sections.

Liu Yujie shook his head helplessly: "These guys have been held back for too long, and they don't even let go of this kind of small warship, forget it, let's leave quickly, and wait until dawn The anti-submarine planes of the Axis countries are coming." ”

The news that a transport fleet was attacked and that a 300,000-ton cargo ship was wiped out along with four escort destroyers quickly reached the Admiralty in Boston, which made the naval bigwigs, who were already anxious about the loss of submarines, even more worried, the enemy had already hit the doorstep, but their sonar and submarines were too different, and they were no match for others at all.

However, the Boston Empire, which was the arsenal of the Axis powers, had to transport a large amount of supplies to the Western Continent, which was difficult for the Admiralty. If it weren't for the closest submarine base of the Chinese Empire, which is also in Cape Town and the port of Rio of the St. Martin Empire at the southernmost point of the Storm Ocean, it is inconvenient to go back and forth, and the number of submarines in the Chinese Empire is not enough, I am afraid that the Boston Navy bosses would have suicidal thoughts. Now they can only increase the number of escort destroyers on the one hand, and report the situation on the other.
