Chapter 559 Hunting the Maritime Self-Defense Force!

 After giving this order, Luo Zhangming glanced at Yang Shuyu who was sitting next to him with some worry.

 Take off with live ammunition, and in non-territorial waters.

 In fact, there are still certain risks.

 Seeing that the latter was looking down at the chart in front of him, and did not stop the staff officer next to him from sending the order, he was relieved.

It wasn't until the series of instructions and replies came to an end that Yang Shuyu asked:

“If two rounds of ammunition are hung at the same time, will the time to perform the mission be affected?”

“Also, if you can finally catch the other party, how are you going to deal with it?”

 As a senior commander who has been away from front-line command positions for some years, he needs to control the command of the ship very accurately.

 Neither interfere too much with the captain's command and dispatch as a professional, nor interfere too roughly, affecting the captain's authority in the minds of the commanders and fighters on the ship.

 But at the same time, it should also serve as a stabilizing needle to ensure that the situation is within control.

Facing the question of the deputy commander of the navy and the pressure from unidentified foreign submarines, it is impossible to say that he is not nervous.

 Meanwhile, about 20 nautical miles away, beneath the surface.

 This is actually an order from the Seventh Fleet.

 But in the past, the actual performance of the Chinese Navy's equipment was always at a discount compared to what it looked like on paper.

“The friendly aircraft is located in the direction of our ship, 20 nautical miles away. We need your aircraft to support us quickly.”

 The task naturally fell on Hai Zi's head.

 Another troublesome thing is that in order to better collect hydroacoustic data, the Winter Tide aimed its bow at the two destroyers head-on. Now this awkward position makes it difficult to retreat.

“In addition, about 55 nautical miles away, there is a louder underwater target, like a train, but it is not fast and should not pose a threat to us in a short period of time.”

“Captain, sonar has detected a surface target using a medium-speed diesel engine about 40 nautical miles away, approaching us at a speed of 25 knots.”

The captain of the submarine SS588 Winter Tide, Second Class Haizawa Yoji Hayakawa, was in the command module, his eyes fixed on the display control screen of the ZQQ-5B digital sonar system in front of him.

“Let me emphasize again, this is not an exercise, there is no plan, and there is no predetermined sea area. Use your special skills. Don't let the target escape under any circumstances!”

“Captain, are we going to sit on the bottom, or...”

 “As for what to do if you find the other party…”

Hayakawa's face was gloomy, but his tone was quite calm:

“This target itself is not a big threat, but unfortunately, the noise of the diesel engine completely covered up the sound of the gas turbine of the other destroyer with it..."

However, now, Captain Hayakawa actually does not need this advanced equipment, because even with just his ears, he can hear the sound waves from active sonar hitting the submarine shell.

"Calculating the time, the helicopter above us now should be about to run out of fuel and return. There may be another one coming to take over. But before I set off, I studied the French-produced helicopter. In the submarine search state, Can't hold on for too long.”

This kind of torpedo was imported from Italy in the late 1980s to fill the vacancies before the Yu-7 torpedo entered service. There are only 40 in total, which is very valuable.

"Although this is not territorial waters, it is also our exclusive economic zone. In any case, if the submarine runs to our pre-demarcated exercise area while submerged, it is a naked provocation. Therefore, I think we must at least force the other party out of the water. No!"

 So I have never dared to push the performance too far.

On the flight deck, after the first helicopter took off, the second helicopter No. 9696 was already preparing to take off just in case.

"yes!"

Winter Tide has quite advanced anechoic tiles laid on its surface. At this distance, the hoisting sonar used by ordinary helicopters is not enough to accurately detect this silent submarine.

The first mate of the boat, Kenjiro Hayashihara and the third class Kaizuo, reported not far away.

 Now after receiving the new order from the captain, it is only necessary to mount another A224 torpedo live ammunition.

The voice of the flight controller came from the radio equipment of the three crew members:

 Luo Zhangming took a deep breath:

"Based on the experience given by the aviation department before, the new helicopter will not have any impact on the basic flight performance in the manual with the standard mount of two radars and hoisting sonar, and it can also ensure that it can complete a mission within a combat radius of 50 nautical miles. Standard submarine search-submarine attack process.”

“The diesel surface target should be the French Navy destroyer.”

 For submarine officers, this sound is almost a death knell.

 So in accordance with the standards of the technical manual, we chose to hang an extra live ammunition to deal with various possible emergencies.

 Until that moment, he suddenly felt confident.

According to the results of sonar analysis, the sound source location should still be about 15 nautical miles away.

However, it is difficult for a huge nuclear submarine to be deployed in the East China Sea, where the water depth is relatively shallow.

The purpose of the Dongtide's voyage this time is to lurk at the edge of the exercise sea area designated by China and wait for the opportunity to collect as much target information characteristics of the Daocheng destroyer as possible.

 A few minutes later, the helicopter took off and flew quickly towards the direction of the two warships.

Luo Zhangming hesitated for a moment, and then replied firmly:

 The three of them answered in unison.

 The former shook his head slightly:

"Don't be in a hurry to sit down. The two destroyers will not arrive nearby for almost an hour. We have to maintain our mobility."

Compared to the experienced Hayakawa, First Officer Hayashihara joined Haizi in 1992 and had never experienced a battle of wits and courage with the Red Navy. Naturally, he was a little panicked when encountering this situation.

 Compared with the old sonar, which can only detect and analyze targets by the sonar operator's ears, the latest digital sonar can more intuitively display the environmental data captured by underwater acoustic equipment like radar.

 In fact, he had heard these data from people in the aviation department before.

  But if this continues, as the other party's search range expands, it will only be a matter of time before it is discovered.

"When the two helicopters take over the mission, we first turn the bow of the boat 90°, and then when the second helicopter returns, they will have a window for searching for submarines. At that time, we can leave at full speed. "

The battery of the Winter Tide can support the submarine to sail at an underwater speed of 22 knots for more than an hour. Thanks to the excellent appearance design and low-noise propellers, the submarine can ensure extremely high quietness when using the battery.

 It's enough to leave this relatively dangerous sea area.

Hayakawa's calm speech restored the calm and orderly atmosphere in the entire command module.

Although generally speaking, submarines have little ability to resist the anti-submarine mode of ship-to-aircraft cooperation, the technical level of the Sea of ​​Japan in the 1990s was so much higher than that of the Chinese Navy that a tie seemed...

 It's not unimaginable.

What excites the crew of the Winter Tide even more is that Hayakawa's timing is very accurate.

 During a significantly longer sonar detection interval than before, the submarine finally completed a difficult 90° turn.

 Next, all we have to do is wait until the second helicopter runs out of fuel and the next time window appears.

 It should be said that there is nothing wrong with Hayakawa Yoji's plan on paper.

However, he didn't know that the first helicopter that had just left had already been conducting submarine searches for a period of time before tracking him.

Therefore, there are some problems with rhythm control... "Captain, 20 minutes have passed. Why does that helicopter... not have any intention of retreating?"

 As time passed by, the command module, which had just regained its composure, became tense again.

In the extended spiral submarine search mode, the helicopter's current position is only about 10 nautical miles away from them.

In principle, the ability of hoisted sonar to judge the direction of a target is relatively weak. If there is only one helicopter searching for submarines, even if the distance to the target is discovered using active mode, it often requires multiple measurements to finally determine the specific location.

  But 10 nautical miles is really a bit too close.

 Even Hayakawa himself gradually began to doubt his previous judgment.

“Captain, if this continues, the opponent's destroyers will get closer and closer...”

 The first mate's voice sounded next to him again.

Compared to ship-based helicopters whose air time is ultimately limited, conventional submarines will lose if they are entangled by surface ships.

 There is almost no other way than to surrender.

Hayakawa originally wanted to find the safest way to leave, but the opponent's helicopter stayed in the air for far longer than expected, which made all previous plans come to nothing.

 Under tremendous pressure, he finally changed his mind:

“Start the battery and maintain a speed of 4 knots.”

However, this decision was made a little too late...

Above the water, the French AS565 helicopter, which was the first to return to replenish its losses, returned to the mission area.

 Although there is no data link, the pilots of the two countries can still communicate in awkward English through the most basic radio.

In fact, aircraft No. 9696 has detected the existence of a target about 8-10 nautical miles away, but it has never been difficult to determine the direction.

Therefore, the Chinese sonar operator who waited for 20 minutes and finally waited for support asked the French helicopter to drop another wave of sonar buoys.

 The latter was completely unaware of the situation and still thought it was part of a normal exercise, so naturally he did as he was told.

They even brought a few extra buoys with them during takeoff this time, trying to save some face for returning early.

"Look at these Chinese people. Although their naval equipment is not advanced, the content of the exercises is so realistic..."

The pilot of the AS565 helicopter said with a slightly emotional tone while launching the buoy in a circular route.

The co-pilot next to him also agreed:

“Yeah, it's even more like an actual battle than a NATO joint exercise. When I was talking to them on the radio just now, I felt some tension.”

“It seems that after the end of the Cold War, our navy has been too relaxed, and many exercises are just a formality...”

“It must be admitted that, at least in terms of exercises, we have completely underestimated the seriousness of the Chinese people...”

Although active and passive sonar buoy arrays lack accuracy and sensitivity, thanks to the fact that many are thrown out at one time, the search efficiency is much higher than that of suspended sonar.

Soon, the French sonar operator discovered an accelerating target at a depth of about 60 meters underwater.

Two helicopters quickly rushed in that direction...

On the underwater Winter Tide, Captain Yoji Hayakawa knew that things were going to be bad when he heard a total of eight things entering the water.

Sure enough, within a few seconds, sound waves from several directions hit the surface of the submarine.

This time, I can't hide it no matter what:

 “Quick, move forward at maximum speed!”

“The ballast tank is filled with water, and the diving depth increases to 100 meters!”

“Also, put the unmanned underwater vehicle (UUV) out and use decoy mode!”

Following his order, a small unmanned submarine fixed behind the hull of the Winter Tide broke away from the mothership and then headed in another direction.

 Because the bait mode was turned on, its propeller left a long series of air bubbles behind it.

While attracting sonar attention, it can also have a certain shielding effect on the mothership itself.

Sure enough, the sonar operator on the French helicopter quickly lost his original target.

“The Chinese also arranged submarine decoys in the exercise?”

  The three French soldiers on the helicopter were already a little doubtful about life.

 But no matter what, today is here. The dignity and face of soldiers require them to fight this "imaginary enemy" to the end.

After a brief communication via radio, the two helicopters began to use hoisting sonar simultaneously to conduct submarine search operations in accordance with the circular search mode of dual-machine collaboration.

Not long after, the third helicopter, the returning No. 9686, also joined the search team.

 In this case, the bait, which does not have a long action time, naturally cannot always guarantee the safety of the Winter Tide itself.

The sound waves emitted by active sonar are like beating gongs and drums, resounding in the ears of the entire submarine crew.

 100 meters underwater, this scene is definitely like a horror story.

Hayakawa still wanted to use up the last bit of battery power.

But he soon heard the heart-stopping payoff.

“3 nautical miles, the projectile entered the water, the speed was 30 knots!”

 Everyone knows that this is an anti-submarine torpedo.

Before everyone could react, they heard a sound far louder than any previous sounds, as if a gong was hitting their ears.

Captain Hayakawa shivered, and it took him a while to realize the source of the sound——

 The torpedo struck, but did not explode.

 It should be a mine.

Even so, the moment the sound rang out, some people with poor psychological quality fainted in the command module of the Winter Tide.

 Hayakawa couldn't guarantee that if he persisted in not refloating, the next time he dropped it would be a live ammunition.

 Furthermore, the battery capacity is no longer optimistic.

 “What a bunch of lunatics…”

Hayakawa sat slumped in front of the podium:

 “Float, float immediately!”
