If we want to select the most mysterious "character" in the Fourth India-Pakistan War, the special forces commanded by Lu Chengwen, the land aerial test force led by Kong Zhigao, the navigation test force where Liang Guoxiang is located, and the air force test force will all compete with the "Swordfish" submarine for the "No. 1 protagonist"; if we select the "character" that has the most fruitful harvest, it is the "Swordfish" submarine.

After the submarine left Yulin Port and entered the deep water channel, Hua Jianfeng and Le Jiacheng opened the command file to put it in the safe in advance.

Then the "Swordfish" headed south at a maximum speed of 27 knots, and after reaching the waters south of the Natuna Islands, it reduced its speed to 16 knots. It followed a VLCC supertanker from Guangzhou to Abu Dhabi and entered the Indian Ocean from the Sunda Strait.

The Sunda Strait, rather than the Malacca Strait, was chosen mainly to avoid the submarines of the US Navy.

The operation of the Swordfish is top secret, and even the existence of the Swordfish is top secret. After the outbreak of the India-Pakistan crisis, the USS Washington aircraft carrier entered Singapore in the name of temporary docking, and several attack nuclear submarines of the Seventh Fleet also entered the Indian Ocean.

The United States will definitely think that the Chinese Navy will send submarines to the Indian Ocean to monitor the Indian Navy.

US submarines will inevitably wait in the Strait of Malacca, waiting for Chinese submarines to fall into the trap. As long as China participates in the war, the United States will inform the Indian Navy of the activities of Chinese submarines to guide Indian anti-submarine forces to encircle and suppress Chinese submarines, and even personally take action to sink Chinese submarines.

Hua Jianfeng cannot take risks. The "Swordfish" set out first, which is to set up a dark chess on the Indian Ocean in advance.

After entering the Indian Ocean, the Swordfish turned north, passed west of the Andaman-Nicobar Islands, and arrived outside the sea of ​​the Rambilan submarine base on the morning of July 1. After selecting the lurking point, the Swordfish reduced its speed to six knots and released a drag-type line sonar of 1,500 meters.

Because the passive sonar array on the side of the Swordfish is too short, it is necessary to use drag-and-drop sonar.

If there are other options, Hua Jianfeng will not use towing sonar. After using towing sonar, the speed of the submarine must be maintained between six and twelve knots and cannot be performed with high-intensity maneuvering. If you need to pursue enemy submarines or avoid enemy submarines, you must retract or cut off the towing sonar. Generally speaking, no submarine captain likes to use towing sonar in actual combat.

Of course, the excellent performance of drag-and-drop sonar is unquestionable.

The "Swordfish" ambushed about fifty-five nautical miles southeast of Rambil. Through the towing sonar, the ships entering and leaving the base and the sounds of the ships making precise positions. Of course, Indian submarines do not want to sneak out from the "ears" of the "Swordfish".

In just one day, the "Swordfish" detected six submarines one after another.

Two 209, two 877-type "Kilo", and two "squids". Hua Jianfeng had no interest in these "little shrimps". He showed "professional instinct". Hua Jianfeng asked the sonar to test the silent performance of the "squid". He found that the French propaganda was very exaggerated. Apart from 120 kilometers, the "Swordfish" drag-and-drop sonar could intercept the "squid" and make noise. He conducted a comparison and analysis. From this, it can be calculated that the "Squid" was at least 115 decibels when it was promoted by the AIP system produced by the D company. Instead of the 95 decibels claimed by the French.

The collective dispatch of Indian submarines attracted the attention of Hua Jianfeng.

After dark, he allowed the submarine to rise to the depth of the periscope. He hoped to receive orders from the General Staff. However, he waited for a night in vain. It was not until dawn that he received the exact news: India and Pakistan were about to start war. He searched and monitored the nuclear submarine "Destroyer".

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

At that time, he was unable to determine whether the "Fighter" was in the base. Nuclear submarines could operate at sea for more than 45 days. After the outbreak of the India-Pakistan crisis, the "Fighter" that acted as a strategic nuclear deterrent could leave the submarine base and enter the Bay of Bengal.

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

Of course, this is by no means "intuition" in a narrow sense.

The "Destroyer" is the first nuclear submarine built by India itself. Its design is the Charles-1 attack nuclear submarine of the former Soviet Navy. In order to have strategic nuclear deterrence capabilities, twelve vertical missile launchers were installed in the hull behind the command platform of the "Destroyer". With a range of only 16k, wàp. The text version launched the "Tactical Ballistic Missile" with a first 1,500 kilometers, and it is difficult for the "Destroyer" to complete the strategic nuclear deterrence mission. This inconsistent design makes the "Destroyer" a four-dimensional design, which is difficult to play a deterrent role like a strategic nuclear submarine, and it is difficult to perform tactical tasks like an attack nuclear submarine.

To solve this problem, the sister boat of the Destroyer, the Combattor, became a test nuclear submarine.

The fate of the "Fighter" was not much better. After entering service at the end of 2011, it took three years to barely form combat effectiveness, and then entered Rambilly to carry out combat readiness patrol missions. In the next year and a half, the attack nuclear submarine of the Chinese Navy only encountered the "Fighter" once, and the encounter area was near Rambilly. The intelligence obtained from other channels also proved that after the "Fighter" was officially put into service, it only carried out combat readiness patrol missions once, lasting less than twenty days, and the active waters were near the base.

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

Hua Jianfeng had enough reason to believe that the "Destroyer" would not leave Rambilly, and even if he went out to sea to carry out combat readiness patrol missions, he would not be too far away from Rambilly.

The patient wait was rewarded soon.

At 10 o'clock in the morning, about half an hour before India announced the launch of a self-defense counterattack, the sonar of the Swordfish heard a strange noise. When the computer judged that the noise source was 170 kilometers away, Hua Jianfeng was a little unbelievable. It was not until the noise data comparison was completed and it was confirmed that it was the "Destroyer", Hua Jianfeng had to believe that India's first nuclear submarine was indeed "high-sounding".

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

Without any hesitation, he ordered the drag-and-drop sonar to be retracted while releasing the communication float. Then the "Swordfish" accelerated to the sixteenth knot and rushed towards the "Destroyer".

At that time, the Destroyer was heading towards Rambilly in the northeast of the Swordfish.

From this, it can be inferred that the "Destroyer" is indeed carrying out combat readiness patrol missions. If China attacks India with weapons of mass destruction, the "Destroyer" will use ballistic missiles carrying nuclear warheads to attack large and medium-sized cities in southwestern China.

However, the "Destroyer" returned to Rambilly, which made Hua Jianfeng a little confused.

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

The noise of the "Destroyer" is as high as 137 decibels, and the noise of the "Swordfish" is less than 90 degrees. It is like a person in a noisy dance hall, and it is difficult to hear the conversation between people next to him. The self-noise of the "Destroyer" is enough to drown out the noise made by other submarines.

Hua Jianfeng had to believe that Indian submarine soldiers had no confidence in their submarines.

The Destroyer must want 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 from north to south in the western Bay of Bengal, and the "Swordfish" is quiet enough. Even if it is attacked by Indian shore-based anti-submarine forces, it can quickly submerge under the warm current. With its excellent silent performance and high-speed navigation capabilities, it escapes from the search range of the Indian anti-submarine aviation force and escapes.

Of course, the Destroyer must be sunk before this.

At around 12:40, the bow main/passive sonar of the Swordfish locked the Destroyer 55,000 meters away.

Hua Jianfeng asked three torpedoes to install fire control data at one time, leaving only one torpedo for self-defense. When any submarine captain attacks the target, he will leave at least one torpedo in case of emergency. In the vast sea, who can be sure that there are no other submarines nearby? If they are attacked by other submarines when attacking enemy boats, is there any torpedo that uses self-defense to determine life and death.

At thirteen twenty, the distance was shortened to 40 kilometers, and the "Swordfish" first launched two line guide torpedoes.

The speed of both torpedoes is set to forty-five knots. At this speed, the noise emitted by the torpedo is less than 100 decibels. With the self-noise level of the "Destroyer", the torpedo can only be discovered when the torpedo approaches 1,500 meters. The shortest self-guided distance of the heavy anti-submarine torpedoes is 2,000 meters. At that time, the sonar soldiers on the "Destroyer" will not hear the noise emitted by the torpedo sailing, but the slap sound caused by the torpedo attacking the sonar.

Hua Jianfeng did not intend to give his opponent any chance. After firing two torpedoes, he put the third torpedo in a state that could be fired at any time and chose a self-guided attack mode with a speed of 70 knots. If the first two torpedoes are lost, 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 because the total length of the wires was only 20 kilometers.

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

Thirteen minutes later, the torpedo's attack sonar was activated.

In just fifteen seconds, the torpedo's attack sonar detected the "Destroyer" nuclear submarine two thousand meters away. Then, the torpedo changed to a high speed mode and the speed quickly increased to 70 knots.

By this time, the "Destroyer", which has a maximum speed of only 24 knots, is already doomed. When attacked by two heavy torpedoes and the reaction time is less than 80 seconds, let alone the "Destroyer", even the "Virginia" will not escape the probability of escaping.

At thirteen forty-nine, the sonar of the Swordfish heard two explosions and the sound of the hull rupture.

After the sound of the hull rupture gradually disappeared, the noise of the "Destroyer" also completely disappeared.

Hua Jianfeng did not rush to celebrate the victory. After releasing the communication buoy, the "Swordfish" turned around and dived at full speed to a maximum safe navigation depth of 560 meters, and at the same time increased the speed to twenty-seven knots.

We must leave this sea before India's anti-submarine aviation forces arrive, and the farther we escape, the better.
