Although submarines generally do not appear in war games, all ships are basically equipped with personnel who specialize in sonar operation. Perhaps this is obsessive-compulsive disorder?

The ships during high-speed navigation are very noisy, so before using active sonar, Arisha actively lowered the ship's speed.

bite--

The sound waves emitted by the sonar sweep into the deep sea and reflect echoes after encountering obstacles.

Through the time delay between the echo signal and the transmit signal, the distance of the target can be calculated, the direction of the target can be calculated from the normal direction of the echo wave front, and the frequency shift between the echo signal and the transmit signal can even the radial velocity of the target.

"The target has been found!" The voice of a sonar girl sounded from the radio inside the bridge.

Because everything happened too hastily, the submarine was caught by the sonar on the Cleveland before it could hide.

"Chasing now!" Arisha said without hesitation.

How could they let go of such a person who came to the door?

The anti-submarine equipment on the Cleveland is quite complete. In Arisha's eyes, this submarine is already a corpse.

The submarine was very slow underwater. The Cleveland quickly caught up with the submarine and then began to attack the submarine.

"Start the hedgehog bomb."

"Abide by the order!"

The Hedgehog bomb is a ship-based anti-submarine weapon. It has a total of 24 gun barrels on its launch frame, which are tilted forward by 45 degrees. So many gun barrels gather together, as if they are like hard thorns on the hedgehog, so they get the name "Hedgehog bomb".

This thing was invented by the British during World War II. Because of its cheap and efficient characteristics, it was quickly promoted to various types of Allied ships.

Under Arisha's command, the hedgehog launcher on the Cleveland immediately started working.

In a very short time, all 24 hedgehog bombs on the launcher were knocked out, forming an oval barrage.

After falling into the water, these 29 kilogram bombs began to sink at a speed of about 7 meters per second.

Since the hedgehog bomb uses a touch-fuse fuse, it will explode after touching the submarine, even if the attack is not successful, it will not interfere with the sonar like a deep water bomb.

In addition, the attacks of the hedgehog bombs are also difficult to detect. The sounds of deep-water bombs entering the water and sinking are obvious, and the submarine responds to them in advance, and the hedgehog bombs have no problem.

After the hedgehog bomb was dropped, the bridge became silent, and everyone seemed to be waiting for the sound of the bomb explosion.

Time passed minute by minute, but the sound of their expectation did not appear for a long time.

"Not hit the target," shouted the sonar.

The effective attack range of the Hedgehog bomb is only more than 200 meters. It is only possible that it has been off the target after not sending messages back for such a long time.

"Carry the next attack right away." Arisa said calmly.

Anti-submarine warfare requires patience, and it is very normal to get empty. If you can hit the target in the first round, you can really buy a lottery ticket.

Plop—

After reconfirming the target's position, another 24 hedgehog bombs fell into the sea.

While the bomb sank, the crew members on the ship prayed, hoping that the attack would work.

These dense bombs cover a large area, and as long as the submarine is in this area, it is likely to be destroyed by hedgehog bombs.

Dong--

I don’t know if the prayers of the girls on the boat worked, but this time, the explosion actually came back under the water.

A hedgehog bullet seemed to hit something, and the fuse located in the front of the bullet body immediately started working, detonating 16 kilograms of TNT explosive stored in the bullet body.

If it is just a hedgehog bomb, it may not be able to sink the submarine on the spot, but the hedgehog bomb is 24 in a round!

The fuse of this thing is particularly sensitive. As long as one explodes, the remaining 23 hedgehog bombs around will also detonate under the impact, causing serious damage to the submarine.

"I've hit it!"

"Everyone did a good job."

Arisha thought they had to spend more time to hit the target, but they ended up throwing it in the second round. It seemed that this AI was lucky.

It seemed to be to prove their results, a lot of oil and floating objects appeared on the sea, and the submarine had obviously become algae chips in the sea.

...

"How did they find out?"

Kelly tilted her head and spoke in confusion.

The submarine just now was actually very ambushed. If the Cleveland doesn't turn on the active sonar, it is actually difficult to find the existence of this thing.

But at that moment, Yin Yu seemed to have learned the news in advance, searched on the water frantically, and finally found the periscope exposed by the submarine.

There was no suspense about what happened afterwards. The Cleveland, who was prepared in advance, easily dodged the submarine's torpedo and then ended the battle with two rounds of hedgehog bombs.

If the organizer is not too authoritative, Kelly would suspect that this is a fake match.

"In this world, some people have the ability to explain it with science." Sophia said leisurely.

"If you can spot an ambush at will... isn't that just cheating?"

"It's cheating, but there is no evidence to prove it." Sophia paused, and then said with a smile: "If you don't get discovered, it's not a crime."

...

After taking down the submarine, Yinyu and his group continued to hunt on the sea.

That's right, it's hunting. This game is too simple for them. AI has almost no power to fight back, and it's even easier than killing a pig.

Compared with them, other teams have to be much more difficult. As the competition progresses, AI ships become more and more powerful and their operations are more sharp.

One player after another was killed by AI in the fight and withdrew from the game with unwillingness to accept it.

Just when they came out, they wanted to find some confidence in other players, they were all frightened by the rankings on the score list.

The first one is of course Yin Yu's team, far ahead of other players, and the scores are even more than the second and third place combined.

Things have become like this. Yin Yu actually has to thank the naughty kids in the monitoring room. If they hadn't sent Yin Yu a high scorer every now and then, the scores on the list would not have risen so quickly.

However, no one cared about this at this time, everyone's attention was attracted by Yin Yu and the others' playing style.

Even if you can't see the target directly, the cannons on the Cleveland can still maintain an extremely high hit rate and become a blind AI ship in a fancy way.

This is really imba, okay? How can you tell others to play like this?
