The aircraft carrier formation was moving fast, but how could they give up this once-in-a-lifetime opportunity, so one by one the electromagnetic energy cannons went straight to the cabin of the target aircraft carrier like ghosts in the deep sea.

David listened to the constant sirens, but he couldn't do anything, at this moment, in addition to urging the helmsman to speed up, he also hoped that the anti-submarine submarine sent by Commander Henry could arrive in time.

Time passed minute by minute, and just when David was at the crossroads, he finally looked forward to the dawn, because the ten anti-submarine submarines sent by Henry arrived.

At this moment, the aircraft carrier formation is not only strong on the water, but also has increased its underwater strength because of the arrival of anti-submarine submarines, and the aircraft carrier is relatively safe, but the stealth submarines controlled one by one have encountered danger.

As the military base gets closer and closer, the depth of the ocean is getting shallower and shallower, although the stealth submarine can dive to a depth of several thousand meters that ordinary submarines can never reach, but there is a premise here, that is, the ocean must have a depth of several thousand meters, if the area where the stealth submarine is located is only five hundred meters deep, then even if the stealth submarine can dive a few thousand meters deep, because when the performance of the submarine is superior, the depth of the ocean determines everything.

At this time, the depth of Yiyi in the sea has risen to 600 meters, and if it continues to advance, it will definitely be exposed.

Some people may wonder if the stealth submarine is not stealthy for sonar detection, and how can it be exposed.

Of course, if it is not visually visible at the same depth, it will not be exposed.

However, the diving depth of the anti-submarine submarine is 500 meters, when the stealth submarine rises to a depth of 500 meters because of the depth of the ocean, although the sonar detection is invisible, but the vision is not stealth, and the anti-submarine submarine in order to find the ghost of the stealth submarine, all turn on the high-energy searchlight, because the biggest reliance of the stealth submarine is the sonar detection stealth, so at the same depth, the stealth effect will completely disappear, then surrounded by more than ten submarines, it is difficult for the submarines controlled by one to not be exposed.

As the depth of the ocean continues to rise, Yiyi is a little anxious, after all, his mission has not been completed this time, if the aircraft carrier is allowed to sail into the military base, then it will be more difficult to complete the task than to ascend to the sky.

In order to complete the mission, Yiyi decided to take risks and continue to chase the aircraft carrier, and then opened full fire, trying to bury the aircraft carrier to the bottom of the sea before it sailed into the military base.

But the ideal is beautiful, but the reality is very cruel, because after controlling the stealth submarine one by one to launch the fifth attack on the aircraft carrier, the diving depth of the submarine also rose to 520 meters, and then a piercing alarm sounded in the stealth submarine, because the stealth submarine at this moment has been locked and hit by the anti-submarine submarine.

So how was the stealth submarine discovered, it turned out that when the fourth attack was launched one by one, the trajectory of the energy core was discovered by the anti-submarine submarine through vision, but because the band search had no effect, they did not startle the snake, but according to the trajectory of the energy core just now, simulated the location of the stealth submarine, but because the energy core is not only small in size, but also fast, so it only simulated an approximate location.

And one by one, in order to speed up the completion of the task, and then fire at full power, which also means that the number of energy cores has also increased, so when the energy cannon was fired for the fifth time, the soldiers on the anti-submarine submarine finally discovered the detailed trajectory of the energy core.

Then when the anti-submarine submarine fired in the direction of the energy cannon, when they were about to reach the limit of the diving depth, they finally discovered the stealth submarine through the naked eye, so the soldiers on the anti-submarine submarine did not hesitate to lock the stealth submarine, and at the same moment, also pressed the fire button.

After hearing the submarine's siren one by one, he knew that he had been discovered and locked by artillery fire, so he controlled the stealth submarine to retreat quickly, as long as it retreated to a depth of 600 meters, then the anti-submarine submarine would be helpless.

Although the speed of the submarine's retreat is rapid, the speed of the anti-submarine submarine is not inferior, and it is not one, but the first of eleven anti-submarine submarines, because the stealth submarine at this moment is in the encirclement of the anti-submarine submarine.

Although the stealth submarine intercepted ten ** through the perfect operation of one by one, unfortunately, one ** still attacked the stealth submarine.

With the strong impact, ** and the stealth submarine came to a close contact, although the hull material of the stealth submarine is a high-strength alloy independently developed by space technology, but such a strong explosion impact also caused damage to the stealth submarine.

However, just when they accelerated their escape speed, twenty-two ** rushed towards the stealth submarine at high speed, although one by one intercepted ten ** with the same accuracy, but it was difficult for two fists to reach four hands, and there were still twelve ** and the stealth submarine came to a close contact.

So after the big explosion, the stealth submarine can be said to be scarred, and the biggest reliance on sonar detection stealth is also because of this big explosion, it has lost its effect, and it can be said that the stealth submarine at this moment no longer has the stealth function.

According to the self-inspection report of the stealth submarine, it is learned that the submarine at this moment has been damaged by 40 percent, and if it is not repaired as soon as possible, I am afraid that there will be a danger of falling to the bottom of the sea.

Although the stealth submarine at this moment is already very dangerous, there is nothing to be done about it.

Because the body is damaged, the speed is also greatly reduced, and the speed of the stealth submarine is similar to the speed of an ordinary submarine at this moment, and the maximum diving depth of the stealth submarine is several thousand meters, and it has become 550 meters.

In order to get out of the crisis, one by one they controlled the submarines and desperately absconded, but the enemy was too strong, so that the damage of the stealth submarines reached 50%.

Just when Yiyi was about to abandon the submarine and eject his carrier and escape alone, it was discovered through detection that there was a cave fifty meters below him, and according to the simulation, as long as the submarine entered the cave, it could escape the pursuit of eleven anti-submarine submarines.

But according to the self-inspection report, the maximum depth of the scarred stealth submarine is 550 meters.

In other words, if you want to reach the cave, you will exceed the current maximum depth of the stealth submarine, and there is a high risk of disintegration.

However, if it is not hidden in time, then the current stealth submarine is likely to disintegrate immediately under the enemy's artillery attack, and in order to win a glimmer of life, it is decided to take risks one by one.

So one by one, they controlled the stealth submarine and dived towards the cave at the fastest speed.
