Jokes are usually only seen at their crew celebration party after the mission.

There is no room for the word joke to exist during a mission.

Lasit immediately asked the sonar crew to turn on the SQR-20 active and passive towed sonar system at the stern of the destroyer, which can carry out a large-range long-range initial detection by changing the underwater towing trajectory.

After some trajectory adjustment, the active and passive towed sonar system is U-shaped, aiming at the direction of the abnormal sound source.

Sure enough, there was no joke.

The anomalous voiceprint was also heard by the active and passive sonars, and this time the voiceprint was clearer than the blurry clip that had been heard at the main sonar base half an hour earlier.

Lassitt's gaze gradually became serious, "Does it mean that the anomalous sound source is closer to us?"

The sonar officer wasn't sure, "Sir, the sound source is too far away from us at the moment, and we can't track the exact direction and speed of the other party through the sound source. ”

"If it weren't for the fact that the sound source was too special, very different from the ship's mechanical sound source, we wouldn't have been able to monitor it at this distance. ”

"But ......"

"Personally, I don't think it's a ship, it's probably a new sound source sample that we haven't collected yet. ”

In the vast sea, not all repetitive and orderly mechanical sound sources are ships, or normal ships.

At least sonar crews have had some special situations.

For example, a few years ago, when piracy was rampant in the Red Sea, countries sent warships to carry out escort missions here. They quietly dropped sonar buoys in the area to collect the propeller voiceprints of these warships.

Then they listened to a very special mechanical sound source that they had never been exposed to before.

The sound is like someone playing a drum in the sea, puff~

They were shocked and thought it was a new warship of a certain country.

The result?

They rushed over in a hurry, trying to get closer to gather information.

Only to find out that it was an old bulk carrier with a burst cylinder and the oil staining the surrounding sea black. As soon as the crew of the freighter saw a warship approaching, they immediately looked as surprised and excited as the lost tourists and the rescue team, and kept calling them for help.

There was another time with a higher laugh.

They also detected an anomalous non-ship-powered mechanical sound source during a maritime mission.

When they rushed over to intercept it, they found that there was a huge mining ship on the opposite side, which was stealing mining materials in the shallow water.

"Whatever it is, we have to be clear that we can't let it become a source of influence that interferes with our operations. ”

"We cannot afford to fail in this mission, and we cannot fail in this mission. Lasitt turned around and ordered the others in the war room, "Pause the radio silence for a minute, and order the third ship to go to the sound source area and investigate the details of the sound source." ”

"Yes!"

……

Ship 3 is a frigate, calculated at a speed of 30 knots per hour, at a fuzzy distance between 500 and 700 nautical miles from the source of the anomalous sound.

It would take the frigate to travel for nearly 100 hours to reach within 300 nautical miles of the anomalous sound source for effective detection.

In fact, there is no need for a corvette.

Within two hours of receiving the reconnaissance order, the Burke-class missile destroyers, whether it was the large sonar base or the active and passive towed sonar system in the tail, clearly captured the anomalous mechanical sound source, and gradually approached the voiceprint characteristics here.

Fuzzy projections from the initial 500 to 700 nautical miles.

to 400 nautical miles, to 300 nautical miles.

and then approaching the anti-submarine blockade line, all passive sonars in the entire blockade line are frantically alarming.

Where is the mechanical noise, it is clear that someone is driving a supercar around them to blow up the street. The sonarists at the various listening posts could no longer hear anything else in their ears, except for the roar of the surging engines that were getting closer and closer, and the roar of the propellers breaking through the waves underwater.

And at this time, the frigate had only run a distance of less than a hundred nautical miles, and it did not run the distance of the sonar detection network of the anti-submarine blockade line.

The command ship was full of chickens and dogs.

It has only been more than two hours since the source of the anomalous sound was discovered.

Even if it was a ship, but the ships at sea sailed as slowly as a turtle, when did it become an F1 rally?

A situation that had never been encountered before made it natural for Lacit to suspect the Behemoth Industries. Aren't they laying an anti-submarine blockade network here to intercept that strange submarine of the Behemoth Industry?

Judging by the voiceprint frequency, it was a giant ship of more than 10,000 tons.

This is similar to the strange submarine in the satellite photo.

If the sonar detects the terrifying speed that is getting closer and closer, then the submarine of the giant beast industry definitely has the strength to depart from the port of Nicaya, in the morning, and soar all the way to the vicinity of this sea area.

Therefore, Lasitt could no longer care about secrecy, and he immediately lifted the radio silence and ordered the whole ship to enter combat mode.

He also asked the three ships of the first blockade line to rush to the aid of the second blockade line at full speed.

With the Burke-class missile destroyer as the core, the two frigates immediately released anti-submarine helicopters and went to the sea area to search.

Hypothesis~

It was really a submarine, with its rugged appearance, if it were to be racing under the sea.

Even without sonar positioning, the helicopter pilot could catch a boiling white wave at sea with the naked eye.

Now, of course, no one wants to believe that it was a submarine.

After some time of flight, the pilots of the two anti-submarine helicopters, and the weapons operators, saw a scene that will never be forgotten.

They saw a huge black ship with a bow section like an aircraft carrier, racing wildly on the blue sea.

The sea that the black giant ship skimmed over was originally calm, but when it passed, it seemed to have set off a twelve-level storm.

The height of the black giant ship was also close to the size of an aircraft carrier, and it did not seem to have the waterline of an ordinary ship, as if it was flying close to the sea......

Even at an altitude of several thousand meters, two anti-submarine helicopters could hear a low, roaring sound that looked like a giant beast roaring through the portholes.

They forgot all the contact response measures that should have been carved into their bodies, and just like that, they went to look at the black "giant beast" on the surface of the sea in the distance.

As they gazed at the "Behemoth", the Behemoth may have also spotted two "birds" hovering in the distant sky.

The huge black ship, which was originally speeding in a straight line on the sea surface, actually drew an arc track on the sea surface in an impossible attitude.

"It'...... It changed course. "Two anti-submarine helicopter pilots, trembling through radio communication.

Then, as if they had just woken up from a dream, they quickly turned on the long-range radio and shouted to the liaison officer of the mothership: "Dock dock, this is a seagull." ”

"You ...... See?"

Both anti-submarine helicopters were hung in camera pods.

After all, they were on a tracking mission, and of course it was necessary to send the flight footage back to the mothership.

Including Commander Lasit, they who were stationed in the command room, of course, saw this scene from the screen.

The communicator in the command room grabbed the intercom with his hand, and he wanted to respond to the call of two anti-submarine helicopters, but when the words came to his lips, they became gibberish.

Commander Lasit slumped in his chair, sweating coldly.

The giant black ship is exactly the same as the picture of the "submarine" in the port taken by the reconnaissance satellite.
