The military-industrial scientific research system of the academic master.

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

It took off with live ammunition, and it was in non-territorial waters.

In fact, there are still certain risks.

He was relieved when he saw that the latter was looking down at the chart in front of him and did not stop the staff officer next to him from issuing instructions.

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

"With two rounds of ammunition hanging at the same time, will the time to perform the mission be affected?"

"Also, if you can finally catch the other party, what are you going to do?"

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 excessive interference in the captain's command and dispatch as a professional nor too rough interference may affect the captain's authority in the minds of the commanders and fighters on the ship.

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

Faced with the question of the deputy commander of the Navy and the pressure from unidentified foreign submarines, it was impossible to say that he was not nervous.

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."

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

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.

So I never dared to push the performance too far.

Until that moment, he suddenly felt confident.

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

"As for what to do if you find the other party..."

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

"Although this is not territorial waters, it is also our exclusive economic zone. In any case, if a 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!"

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

Now after receiving the captain's new order, it only needs to hang another A224 torpedo live ammunition.

This type of torpedo was imported from Italy in the late 80s to fill the vacancies before the Yu-7 torpedo entered service. There are only 40 of them in total, which is very valuable.

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

The flight commander’s voice came from the radio equipment of the three crew members:

"I stress 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!"

"Yes!"

The three of them answered in unison.

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

……

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

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

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.

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

For a submarine officer, the sound is almost a death knell.

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

The 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.

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

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

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

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

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

"The diesel surface target should be the French Navy destroyer."

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

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

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

This is actually an order from the Seventh Fleet.

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

The task naturally fell on Hai Zi's head.

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

Compared with 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.

The former shook his head slightly:

"Don't rush to sit on the bottom. The two destroyers will not arrive nearby for about an hour. We have to maintain our mobility."

"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 long.”

"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.

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, but in the 90s, the technical level of the Japanese Navy surpassed that of the Chinese Navy by so much that a tie seemed...
