"The left full rudder turns 90 degrees, slows down to 15 knots, and prepares to release the water demon (Nixie, model AN/SLQ-25, scientific name surface ship torpedo defense system, is an acoustic decoy. In short, this thing will be very noisy all the time after it is thrown out of the back of the boat and turned on, and the noise is very similar to that of a boat, and the volume is louder than that of a real ship, so the voice-activated torpedo will think that this is the real boat and crash headfirst into the bait. ）！ ”

Before the other tourists could react to what was happening, Chiba's face had changed - he had become the most sensitive to the ship's deceleration outside of the seafarers because of the additional perception given to the auxiliary unit.

Before Qianyu could react to the fact that Qianyu gently clasped Gray Yuan's hand, the entire ship suddenly began to turn left at a great angle. "Ahh

"Please keep your balance! Take care of your children! Inoue woke up like a dream, and hurriedly reminded all the passengers - most of the passengers did not expect such a thing to happen at all, so they were all extremely embarrassed (including Chiba and Ashbara), except for ......

Inoue glanced at the white-haired woman with a look of consternation - compared to the embarrassment of the others, she seemed to be completely unaffected, still holding a folding fan and quietly watching everything that happened in front of her.

Just as the other tourists were recovering from the chaos, a middle-aged man walked into the center of the war with a young woman: their costumes indicated that they were Self-Defense Force officers.

"Confirm the data of friendly submarines at the Ichiya base and the nearby waters, notify the bridge, issue a warning immediately after the horn is sounded, and at the same time send radio warnings in as many frequency bands as possible, giving priority to sending targets to friendly bands, Far Eastern bands, Russian bands! The helicopter immediately rose into the air and confirmed the target, anti-submarine weapons were on standby. "From his constant giving orders and his voice, it can be seen that this middle-aged man is the captain of the ship, Tateishi." Immediately after releasing the water demon, it re-accelerates and navigates at combat speed! ”

"α target velocity remains the same, the distance is 2800!"

"The same speed?" The captain made an empty chair and looked at the display in front of him—on the interface, the coordinate points representing the unknown submersible were moving in a curve, but this was obviously because his ship was also in irregular motion, making the relative coordinates of the unknown submersible that was originally moving in a uniform straight line move in a curve. "We've all apparently spotted them, and they're moving at the same pace?"

"Yes! We did not detect the propeller's voiceprint, speculating that it may be silent submersible or unpowered drifting. ”

"The helicopter with an anti-submarine torpedo and a group of depth charges will be detected as soon as possible, and the ship will go around the back of the opponent at combat speed and closely observe the reaction of the opponent!" The captain frowned slightly, and finally gave such an order. "Especially the sonar continues to probe, and let me know as soon as there is news."

……

"I feel like the atmosphere here is getting tense throughout," Ayumi asked Conan, looking at everything that was going on in front of her with a little concern. "Could something really happen?"

"Don't worry, this should be the content of the drill!" Mitsuhiko next to him said with relief. "It's normal to act realistically!"

"For the time being, it shouldn't be bad to think of it as a drill, so don't be too anxious." At this time, Conan was very calm - they were on this ship, and it was impossible to change what would happen next, so it didn't make sense to tell Ayumi what he thought.

It's just that, if you think about it, maybe their ship is really in trouble now, right?

"Actually, I don't think it's right," said Moriran, who was beside them, expressing his concern to Sonoko Suzuki. "If this is really part of the exercise, then the contrast between the front and back is too strong, and it is like judging two people at all."

"Hmm......" After hearing Maoliran's words, Suzuki Sonoko also took a closer look at the expressions of the Self-Defense Force members in the CIC, but in the end, she just motioned to Maoliran to look at the young female self-defense officer who walked in with Captain Tateishi, but at this time, she was just like an idler, standing behind the rather nervous captain. Maybe it's because of her? Maybe it's because she appeared here that everyone suddenly became nervous, maybe she was the evaluator in charge of measuring the quality of this exercise, and she really couldn't stand it anymore so she came over to ask them to be serious? ”

At this moment, a command from the front attracted everyone's attention.

"Single warning shot, fire!"

Immediately afterward, there was a fairly clear sound of firing along the solid structure of the ship's cabin.

At the same time, Captain Tateishi got a reply to the request to the shore.

In this reply, the waters around this should not be free of any friendly submersibles.

Although the submersible is located outside the territorial sea line, it is still essentially part of Japan's semi-territorial waters, and the naval forces of the Far East and Russia are hardly present here, not even in reconnaissance records.

Could it be ...... Is it North Korean? However, their submarines should be mainly miniaturized and old-fashioned configurations, but now the submersible that has been detected is a little larger than North Korea's existing equipment, and it is somewhat strange that it has not been detected by passive sonar - in terms of North Korea's technical level and equipment level, even if it develops a long-range submarine, the operating noise must be amazing, but in that case, passive sonar should be able to detect movement in time.

Even if it is a scientific research submarine, there is no reason not to respond to their messages, not to mention that there are no large-scale fish schools found in this vicinity after sonar detection, and there are no special landforms on the chart.

Could it be that the submersible that had an accident during an ocean voyage was carried here by the ocean currents because the hull structure of the ship had been intact? It is still possible if the occupant is disabled for some reason.

Continue today's joy to find faults, or this clip.

At 14 minutes and 57 seconds, when the shipwreck was 3200-3100 meters away, a close-up of the display was given, and the Pythagorean theorem could be used to determine that the side length of a small grid above was 1000 meters.

Then, the speed of the movement of that little dot that represents the shipwrecked ship—off-spectrum—

At about 16 minutes, the shipwreck was on the same grid, and it took only four seconds to climb through a small grid in a long shot...... Or climb the full diagonal diagonal......

4 seconds, 1414 meters, 353 meters per second...... Okay, I can't see that our shipwreck comrades are really real people and are actually sneaking at supersonic speeds......

And then, at the end of the metal reaction, it was revealed that the fishing boat did not have any metal components.

In other words, without an engine, without a propeller, such a ship sails in the open sea.

And to be reasonable, metal reaction = 0.00% (the result of the analysis on the Aegis screen) does not mean that the explosive load is likely to be 0...... Plastic bombs are not easy to get through security......
