"All targets have been successfully shot down, so today's visit to the exercise..."

Before Inoue Fumitada finished speaking, he suddenly heard a self-defense officer say in shock:

"Sonar response measured, nationality unknown, target A started to detect."

The Aegis ship is equipped with the Aegis combat system.

If the information matches...

Ye Geng took a few steps to the side and looked at the sonar monitor as fully as possible.

These few steps were naturally a few centimeters beyond Inoue Fumitada's position as a reference. However, the atmosphere in the entire cIc was extremely solemn at this time, and no one paid attention to him.

Hmm... The model of the sonar kit is indeed AN\\/Sqq-89. It consists of a spherical sonar array on the bow, a long-range low-frequency sonar on the side of the ship, and a towed sonar array on the stern.

To put it simply, the principle is to emit sound waves and receive the signals reflected back. By analyzing and processing the sound waves, the position, distance, speed and characteristics of the underwater target can be determined.

The air-to-air exercise is over. In other words, is it another unknown object from the sea?

"The other party is approaching our ship!"

"A target bearing is 5 degrees, distance is 8000..."

"A target bearing is 50 degrees, distance is 7500..."

“Understand and prepare for the possibility of the target temporarily shifting gears.”

"Prevent possible attacks from targets."

"The possibility of living things, natural objects, is zero."

"Identification Friend or Foe signal not responding."

"It was a submersible object that did not belong to friendly forces."

"Activate Nixie! The ship stops at its current position!"

"Back, full left rudder 90 degrees, bow aligned with the target and then stationary..."

Reports and instructions came and went.

And as the moving Aegis ship completed this series of actions and actually stopped, the confusion on Conan's face completely turned into surprise.

The so-called Nixie is an anti-torpedo system consisting of a towed main launcher, jammer and control system.

Its working principle is roughly to emit a sound signal similar to the sound of a ship's engine to interfere with and attract the detection and detonation mechanism of the torpedo to deflect it from the target.

"The drill suddenly became more realistic."

Mouri Kogoro didn't seem to understand the situation yet.

But I don't know if it was a coincidence or not. After being misled by him, the visitors who came to observe the anti-aircraft exercise calmed down a lot.

Seeing that everyone's thoughts were still on the 'exercise', Inoue Fuminada quickly calmed down his emotions even though he was nervous.

In fact, as a third-class Kaizuo, he was higher than some of the self-defense officers in this room. However, he could not participate in the battle planning at this time to avoid causing panic.

"Fight against submarines and transmit luminous signals!"

"Understood, flare ready... luminous flare, launch!"

"Soon to be displayed on the third home screen!"

It seems that the previous anti-torpedo system was not attacked.

This signal flare can be regarded as a warning method, used to release a detected signal to unknown divers...

Gee, I don’t know if throwing the Death God primary school student into the sea now can avoid bad luck...

The moment Ye Gengyi dispersed his thoughts, the third main screen also showed the real-time picture of the flare being fired.

"Hey! Yes, yes! Take a look."

"Yeah yeah!"

"It's so handsome!"

Finally, it was no longer a cheap pixel animation, and the three children could not help but cheer.

Suzuki Sonoko tilted her head and asked Mao Lilan: "I didn't expect that the signal flare was so bright even in the daytime! Is this true?"

"How is that possible?" Mao Lilan was still immersed in the atmosphere of the exercise.

Unexpectedly, two attempts without any feedback had already made the captain of the Aegis ship, Yukio Tateishi, feel as heavy as the atmosphere in the room.

"Target a continues to approach, the distance is 4500 meters..."

Another report that was enough to make my nerves tense reached my ears.

Damn it, we can’t wait any longer!

Yukio Tateishi took a deep breath and made the final decision: "Everyone is ready for a submarine battle..."

He paused briefly, looked at Inoue Fumada, who was responsible for guiding the visitors, and reminded him in a very direct way:

"Red Alert!"

"...Sir, please!" Fumita Inoue hesitated for less than half a second before accepting the order.

Red alert refers to a state when a ship is on high alert and may face enemy threats or emergencies.

When a ship enters a red alert state, all personnel on the ship will immediately be prepared to respond to threats or emergencies, and non-related tasks being performed will also be interrupted or postponed to ensure the safety of the ship as the first priority.

But... the equipment of this Aegis ship is too poor, right?

Ye Gengyi stared at the data on the screen in silence.

The distance of the unknown diving object was close to 4,000 meters, but the pulse electromagnetic wave equipment of the phased array radar system was unable to analyze and provide an effective detection pattern after receiving the detection data of the return wave signal.

What is the radar model...

He was still thinking.

Here, the next instruction from Yukio Tateishi, who was in command, gave the answer:

"Stop SpY1 detection immediately! Send Sh60K helicopter to confirm the target!"

SpY-1?

Ye Geng only remembered that this radar seemed to be installed on the American Arleigh Burke-class destroyers and Taconderoga-class guided missile cruisers, but he couldn't really recall the specific parameters for a while.

Xiaobai~lightnovelpub.net~Is there corresponding information in the database?

Ye Gengyi no longer bothered to think too much.

Sufficient ability, but not showing the ability you should have? So this is the emasculated version sold by the United States to the Japanese Self-Defense Forces?

Well, that's really a deep love between father and son... Ye Gengyi sighed with a double entendre.

In this way, it also lowered the safety level of this incident.

The reasons for launching a war are complex and diverse. In the absence of specific information, a detailed analysis will not be made here.

However, there is one thing that no decision-maker can avoid, and that is the consumption of financial resources.

If the unknown object in the water has the ability to sink the warship in a short period of time, then based on probability analysis, it or its operator should do more important tasks.

After all, approaching at this speed, in the sea where the signal cannot be completely blocked, the news here has already been passed on.
