If the most mysterious "role" in the Fourth Indo-Pakistani War is to be selected, the special forces commanded by Lu Chengwen, the Army Aviation Test Unit led by Kong Zhigao, the Navy Aviation Test Unit to which Liang Guoxiang belongs, and the Air Force Test Unit will all compete with the "Swordfish" submarine for the "number one protagonist"; If the most fruitful "role" is selected, it must be the submarine "Swordfish".

After the submarine left Yulin Port and entered the deep-water channel, Hua Jianfeng and Le Jiacheng opened the order document that was put into the safe in advance.

The Swordfish then sailed south at a top speed of 27 knots, and after reaching the waters south of the Natuna Islands, it reduced its speed to 16 knots and followed a VLCC supertanker from Guangzhou to Abu Dhabi from the Sunda Strait into the Indian Ocean.

The Sunda Strait, over the Strait of Malacca, was chosen primarily to avoid the submarines of the US Navy.

The actions of the "Swordfish" are top secret, and even the existence of the "Swordfish" is top secret. After the outbreak of the Indo-Pakistani crisis, the aircraft carrier "Washington" was stationed in Singapore under the pretext of a temporary dock, and several attack nuclear submarines of the Seventh Fleet also entered the Indian Ocean.

The United States would surely have imagined that the Chinese Navy would send submarines to the Indian Ocean to spy on the Indian Navy.

U.S. submarines are bound to wait in the Strait of Malacca, waiting for Chinese submarines to fall into the net. As long as China enters the war, the United States will inform the Indian Navy of the activities of Chinese submarines, guide India's anti-submarine forces to encircle and suppress Chinese submarines, and even personally sink Chinese submarines.

Hua Jianfeng couldn't take risks, and the "Swordfish" set off first, which was to lay a dark chess piece in the Indian Ocean in advance.

After entering the Indian Ocean, the Swordfish turned northward, passing west of the Andaman and Nicobar Islands and reaching the waters off Rambilly Submarine Base on the morning of 1 July. After selecting the lurking spot, the Swordfish reduced its speed to six knots and released a towed line sonar with a length of 1,500 meters.

Because the passive sonar base array on the side of the "Swordfish" was too short, it had to use towed sonar.

If there were other options, Hua Jianfeng would not use drag-and-drop sonar. With towed sonar, the submarine must maintain a speed between six and twelve knots, and it is not yet capable of high-intensity maneuvers. If it is necessary to pursue an enemy submarine, or to evade an enemy submarine, it must be retracted, or the towed sonar must be cut off. In general, no submarine commander likes to use towed sonar in real combat.

Of course. The excellent performance of the towed sonar is unquestionable.

The Swordfish was ambushed about 55 nautical miles southeast of Rambilly. By dragging sonar. Ships entering and exiting the base can be heard clearly. and the sound of the ground from the ship. And precise positioning. Of course. Indian submarines should not try to slip out from under the "ears" of the "Swordfish".

Just one day. The "Swordfish" has detected six submarines in succession.

Two ships 209. Two Type 877 "Kilo". There are also two "squid". Hua Jianfeng has no interest in these "little shrimps". out with the "professional instinct". Hua Jianfeng asked the sonar chief to test the mute performance of the "squid". It was found that the French propaganda was very exaggerated. One hundred and twenty kilometers apart. The "Swordfish" ground-towed sonar can intercept the noise of the "squid". And a comparative analysis is carried out. It can be calculated from this. "Squid" is being propelled by the AIP system at the production site of Company D. The noise is at least 115 decibels. And not the French claim ninety-five decibels.

Indian submarines were dispatched en masse. It has aroused great attention from Hua Jianfeng.

After dark. He allowed the submarine to rise to periscope depth. I hope to receive an order from the General Staff. It's just that. He waited in vain all night. Until after dawn. Only then did I receive definite news: India and Pakistan are about to go to war. Search and surveillance of the nuclear submarine "Fighter".

After receiving the order, Hua Jianfeng immediately let the "Swordfish" dive to a depth of 250 meters.

At the time, he was not sure if the Destroyer was inside the base. Nuclear submarines can operate at sea for more than 45 days, and after the outbreak of the India-Pakistan crisis, the "Destroyer," which acts as a strategic nuclear deterrent, may leave the submarine base and enter the Bay of Bengal.

With the "intuition" he learned from Lu Chengwen, Hua Jianfeng felt that the "Destroyer" was nearby.

Of course, this is by no means "intuition" in the narrow sense of the word.

The "Fighter" is the first nuclear submarine built by India itself, and the original design is the "Charlie-1" attack nuclear submarine of the former Soviet Navy. In order to have a strategic nuclear deterrent capability, twelve vertical missile launch tubes are installed in the hull behind the command platform of the "Fighter". With a range of only 16 k, the "tactical ballistic missile" launched 1,500 kilometers in the text version of the novel, the "Destroyer" could hardly accomplish the task of strategic nuclear deterrence. This nondescript design makes the "Destroyer" a four-way street, which is difficult to play a deterrent role like a strategic nuclear submarine and to perform tactical tasks like an attack nuclear submarine.

To solve this problem, the sister boat of the "Fighter" "Fighter" was turned into a test nuclear submarine.

The fate of the "Destroyer" did not go much better, and after entering service at the end of 2011, it took three years to barely build up its combat effectiveness, and then stationed in Rambili to carry out combat readiness patrol missions. Over the next year and a half, the Chinese Navy's attack nuclear submarine encountered the Destroyer only once, off Rambilly. Intelligence obtained from other sources also proves that after the "Fighter" was officially put into service, it only carried out one combat readiness patrol mission, which lasted less than 20 days, and the sea area of activity was near the base.

Such a nuclear submarine can be counted only as an expensive "iron vase".

Hua Jianfeng has every reason to believe that the "Destroyer" will not leave Rambilly, and even if it goes to sea to carry out combat readiness patrol missions, it will not be too far from Rambilly.

The patience soon paid off.

At 10 a.m., about half an hour before India announced the launch of a self-defense counterattack, the sonar chief of the "Swordfish" heard a strange noise. When the computer judged that the source of the noise was 170 kilometers away, Hua Jianfeng couldn't believe it. It wasn't until the noise data comparison was completed and it was determined that it was the "Fighter" that Hua Jianfeng had to believe that India's first nuclear submarine was indeed a "loud voice".

When quietly approaching the "Destroyer", Hua Jianfeng received a battle order from the General Staff.

Without hesitation, he ordered the towed sonar to be retracted, and the communication buoy was released, and then the "Swordfish" accelerated to 16 knots and killed the "Destroyer".

At that time, the "Destroyer" was to the northeast of the "Swordfish" and was moving in the direction of Rambilly.

It can be inferred from this that the "Destroyer" is indeed carrying out combat readiness patrol missions, and if China attacks India with weapons of mass destruction, the "Fighter" will attack large and medium-sized cities in southwest China with ballistic missiles carrying nuclear warheads.

It's just that the "Destroyer" returned to Rambilly, which made Hua Jianfeng a little puzzled.

Could it be that the whereabouts of the "Swordfish" were discovered by the "Destroyer"?

The noise of the "Destroyer" was as high as 137 decibels, and the noise of the "Swordfish" was less than 90 decibels. It's like being in a noisy ballroom and it's hard to hear the conversation of the people next to you. The self-noise of the "Destroyer" was enough to drown out the noise emitted by other submarines.

Hua Jianfeng had to believe that the Indian submariners did not have any confidence in their submarines.

The "Fighter" definitely wants to return to the waters near Rambilly and operate under the cover of shore-based anti-submarine aviation and small anti-submarine ships.

Hua Jianfeng didn't care about this.

There is a warm current running from north to south in the western Bay of Bengal, and the Swordfish is quiet enough. Even if it is attacked by India's shore-based anti-submarine forces, it can quickly dive under the warm current, and with its excellent silent performance and high-speed navigation ability, it can escape from the search range of India's anti-submarine aviation and slip away.

Of course, the "Destroyer" must be sunk before that.

At around 12:40 p.m., the Swordfish's bow active/passive sonar locked onto the Destroyer, which was 55 kilometers away.

Hua Jianfeng set fire control data for three torpedoes at one time, leaving only one torpedo for self-defense. Any submarine captain will leave at least one torpedo behind when attacking a target, just in case. In the middle of nowhere, who can be sure that there are no other submarines nearby? If you are attacked by other submarines while attacking an enemy boat, whether or not you have a torpedo to defend yourself will make the difference between life and death.

At thirteen:20 a.m., the distance was reduced to forty kilometers, and the "Swordfish" first fired two wire-guided torpedoes.

The speed of both torpedoes was set at forty-five knots. At this speed, the noise emitted by the torpedo is less than a hundred decibels. With the self-noise level of the "Destroyer", the torpedo can only be spotted when it approaches 1,500 meters. The minimum self-homing distance of a heavy anti-submarine torpedo is two kilometers, and when the time comes, the sonar crew on the "Destroyer" hears not the noise made by the torpedo while sailing, but the slapping sound of the torpedo attack sonar.

Hua Jianfeng did not intend to give his opponent any chance, and after firing the two torpedoes, he put the third torpedo in a state that could be fired at any time, and chose the self-guided attack mode with a speed of 70 knots. If the first two torpedoes miss, the third torpedo must be fired immediately.

In fact, Hua Jianfeng's preparation was a bit redundant.

Fourteen minutes later, the wires on the two torpedoes fell off automatically, since the total length of the wires was only twenty kilometers.

Next, the torpedo will approach the target along a preset course under the control of an inertial guidance system.

After another thirteen minutes, the torpedo attack sonar was activated.

It took only fifteen seconds for the torpedo attack sonar to detect the "Fighter" nuclear submarine two thousand meters away. Immediately, the torpedo switched to high-speed mode, and the speed quickly increased to seventy knots.

By this time, the "Destroyer", which had a maximum speed of only 24 knots, was already in danger. In the case of being attacked by two heavy torpedoes and the reaction time is less than 80 seconds, not to mention the "Destroyer", even if it is the "Virginia", the probability of escape will not exceed 4 percent.

At 13:49, the sonar chief of the "Swordfish" heard two explosions and the sound of the hull breaking.

After the sound of the hull cracking gradually died down, the noise of the "Destroyer" also disappeared completely.

Hua Jianfeng was not in a hurry to celebrate the victory, and after releasing the communication buoy, the "Swordfish" turned around and dived at full speed to the maximum safe sailing depth of 560 meters, and at the same time increased the speed to 27 knots.

It is necessary to leave this sea area before the arrival of India's anti-submarine aviation, and the farther away the better.
