Although submarines are not usually seen in war games, each ship is basically equipped with personnel who specialize in operating sonar, maybe this is obsessive-compulsive disorder, right?

The boat at high speed was very noisy, so Arisa took the initiative to reduce the speed of the boat before using active sonar.

Ding——

The sound waves emitted by the sonar swept into the deep ocean and reflected echoes after encountering an obstacle.

The distance of the target can be deduced from the time delay between the echo signal and the transmitted signal, the direction of the target can be deduced from the normal direction of the echo wavefront, and the frequency shift between the echo signal and the transmitted signal can even reach the radial velocity of the target.

"Found the target!" said the sonar girl's voice over the radio inside the bridge.

Because everything happened so quickly, the submarine was caught by the sonar on the Cleveland before it could take cover.

"Pursue it now!" Arisa said without hesitation.

How can they let go of this kind of head sent to the door?

The anti-submarine equipment on board the Cleveland is quite perfect, and in Arisha's eyes, the submarine is already a corpse.

The submarine was very slow underwater, and the Cleveland quickly caught up with the submarine and began an attack on the submarine.

"Shoot the hedgehog round. ”

"Yes!"

The Hedgehog Bullet is a shipborne anti-submarine weapon with a total of 24 barrels on the launcher and a 45-degree forward inclination. So many barrels gathered together, as if they were hard thorns on a hedgehog's body, hence the name "hedgehog bullet".

Invented by the British during World War II, it was quickly introduced to all types of Allied ships due to its inexpensive and efficient nature.

On Arisha's orders, the Hedgehog Launcher on the Cleveland immediately became operational.

In a very short period of time, all 24 hedgehog shells on the launcher were shot out, forming an oval-shaped barrage.

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

Since the hedgehog bomb uses a contact fuse and does not explode until it touches the submarine, even if the attack is unsuccessful, it will not interfere with the sonar like depth charges.

In addition to this, the attacks of the hedgehog bullets are also difficult to detect. The sound of depth charges entering and sinking is noticeable, and submarines react to them in advance, while hedgehog shells do not have this problem.

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

Minutes and seconds passed, but their voices of anticipation did not appear for a long time.

"Didn't hit the target. The sonar officer shouted.

The effective attack range of the hedgehog bullet is only more than two hundred meters, and if there is no news for so long, it may only be off target.

"Immediately for the next attack. Arisa said unhurriedly.

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

Puff –

After reconfirming the location of the target, another 24 hedgehog shells fell into the sea.

As the bomb fell, the ship's crew prayed for the attack to work.

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

Knock –

I don't know if the prayers of the girls on the boat worked, but this time the sound of explosions really came back from underwater.

A hedgehog bullet seemed to hit something, and the fuse located in the front of the bomb immediately worked, detonating 16 kg of TNT stored in the bomb.

If it's just a hedgehog bullet, you may not be able to sink a submarine on the spot, but a hedgehog bullet is a round of 24 shells!

The fuse of this thing is particularly sensitive, and if one of them explodes, the remaining 23 hedgehog shells around it will also detonate under the impact, causing serious damage to the submarine.

"Hit!"

"Well done. ”

Arisa thought it would take them a little longer to hit their target, but they hit it in the second round, and it seems that the AI's luck is a bit back.

As if to prove their success, a lot of oil and floating debris appeared on the surface of the sea, and the submarine had obviously become algae debris in the sea.

……

"How did they find out?"

Kelly tilted her head and spoke in confusion.

The submarine was actually very well ambushed, and if the Cleveland didn't turn on the active sonar, it would be difficult to detect the existence of this thing.

But at that moment, as if he had learned the news in advance, Otowa frantically searched the water, and finally found the periscope exposed by the submarine.

After that, there was no suspense, and the Cleveland, which had prepared in advance, easily dodged the submarine's torpedoes, and then ended the battle with two rounds of hedgehog rounds.

If it weren't for the authority of the organizers, Kelly would have suspected that it was a match-fixing.

"There are people in this world who have the ability to explain it with science. Sophia said leisurely.

"If you can spot an ambusher casually...... Isn't that cheating?"

"It's cheating, but there's no evidence to prove it. Sophia paused, then smiled and said, "If you don't find out, you don't commit a crime." ”

……

After taking the submarine, Otowa and his party continued to hunt at sea.

That's right, it's hunting, this game is too simple for them, the AI barely has any power to fight back, it's even easier than killing a pig.

Compared to them, the other teams are much more difficult. As the race progresses, the AI's ships become more powerful and sharper.

One contestant after another was killed by the AI in the fight, and he withdrew from the game with reluctance.

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

The first place is, of course, Otowa's team, far ahead of the other players, and even more points than the second and third places combined.

Things have turned out like this, Otoha actually has to thank the bear child in the monitoring room, if it weren't for the people who sent Otoha high scores every once in a while, the score on the list would not have risen so quickly.

But at this time, no one cared about this, and everyone's attention was attracted by the way Otowa and their playing style.

Even if the target cannot be seen directly, the guns on the Cleveland can still maintain an extremely high hit rate, and the fancy blaster becomes a blind AI ship.

It's so imba, okay, how are you going to tell other people to play like this!

Many players who have just been sent out by AI are going to vomit blood in anger, why can people brush and brush without brains, they have to fight to the death?
