The red lights began to flicker, sounding the silent battle alarm.

Sideways past a sailor heading to the engine room, ascending three steps, Hua Jianfeng walked into the command center.

"First to fifth, slow down, control the speed." Patting the helmsman's shoulder, Le Jiacheng nodded at Hua Jianfeng and said, "The identity of the target has just been determined, it is the 'Vikrant' aircraft carrier." ”

After handing the hat to the chief engineer standing by the door, Hua Jianfeng walked to the side of the sonar console.

"Azimuth 315, distance 35, target course 105, speed 24." The sonar chief looked excited. "Captain, we've caught a big fish."

"Well done. Did you spot the Vikramaditya? ”

The sonar chief shook his head and said, "Only the 'Vikrant' was found. In addition, there are a large number of noise sources in the direction of 345, more than sixty kilometers away, and it is impossible to identify them. ”

"Most likely, it's the USS Vikramaditya aircraft carrier battle group." Le Jiacheng added.

Hua Jianfeng nodded and motioned to the sonar chief to display the information on the large screen of the fire control computer.

Because the submarine was in a combat state and could encounter the Indian aircraft carrier battle group at any time, the "Swordfish" withdrew its towed sonar before reaching the ambush area, and only used the shell sonar and bow spherical sonar to search for targets. In this case, the passive detection capability of the "Swordfish" is greatly reduced.

Dense dots of light appeared on the large LCD screen on the fire console.

The slow-moving green dot of light is a surface battleship. The fast-moving ground yellow dot of light is an anti-submarine aircraft. There are no red spots of light representing submarines. The source of ground noise in a 345-degree direction is represented by a large green point of light. This indicates that the number and nature of noise sources cannot be accurately measured.

The "Vikrant" aircraft carrier battle group is a loose anti-submarine formation. There were twelve anti-submarine aircraft in the air.

"We are in the best position to attack. Now launch the torpedo. The chances of escaping from the ground are more than 80%. ”

Lejiachengdi's voice was very low. But the command center is such a big place. The surrounding officers heard it.

Now for it. Isn't it too urgent?

Hua Jianfeng glanced at everyone. The eyes are back on the big screen.

"Swordfish" is located directly southeast of "Vikrant", at a distance of thirty-five kilometers.

The minimum firing range of a 533-mm heavy torpedo was forty-five kilometers. Two torpedoes could inflict heavy damage on the "Vikrant", and three torpedoes could sink the "Vikrant". Can a distance of 35 kilometers allow the "Swordfish" to retreat in its entirety?

"Torpedoes No. 1, 2 and 3 enter fire control data and prepare for ......"

"Captain, there's contact."

Hua Jianfeng was startled and immediately waved his hand to stop Le Jiacheng from conveying the order.

"The anti-submarine patrol aircraft, azimuth 305, distance 7, is moving at high speed in front of me."

When the sonar chief reported the relevant data, a high-speed moving red dot appeared on the screen, and the result of computer analysis was: P-8I anti-submarine patrol aircraft.

"Lao Hua ......" Le Jiacheng suddenly became nervous.

Hua Jianfeng pressed his hand and didn't let Le Jiacheng continue.

Support anti-submarine tactics are very non-standard, and anti-submarine patrol aircraft only patrol 35 kilometers in front of the aircraft carrier battle group. According to standard tactics, anti-submarine patrol aircraft should expand the search range to more than 150 kilometers to prevent submarines from attacking aircraft carrier battle groups with anti-ship missiles.

This cannot be blamed on the Indian Navy, there are only a few P-8Is, and the Octave Strait is not spacious.

In less than five minutes, the P-8i flew away about eight kilometers northeast of the Swordfish. Probably, too many sonar buoys were wasted in the Bay of Bengal before, or they just came to make a show, and the anti-submarine patrol aircraft did not strictly follow the tactical norms, dropping sonar buoys at most every twenty kilometers.

As the red light point disappeared from the lower right corner of the screen, everyone breathed a sigh of relief, and Le Jiacheng secretly wiped the sweat from his forehead.

Hua Jianfeng saw not danger, but opportunity.

The anti-submarine focus of the Indian aircraft carrier battle group is on the periphery, not on the inside of the formation. If it can get inside the formation, the "Swordfish" will not only be able to launch an attack by surprise, but also avoid the enemy's anti-submarine forces. The premise is that the "Swordfish" must slip in without being detected.

"First five, tail five, depth 540, course 45, speed 6." Hua Jianfeng didn't hesitate any longer, "Lao Tzu wants to learn from Sun Monkey and toss it in the belly of the white bone spirit." ”

"Into the inner layer of the battle group?" Le Jiacheng was secretly shocked, Hua Jianfeng's courage was too big.

"The most dangerous place is the safest place." Hua Jianfeng tapped on the panel of the LCD screen. "The Indian aircraft carrier battle group uses a common anti-submarine formation, with six escort warships scattered in front of the aircraft carrier, left and right sides, and twelve anti-submarine helicopters all concentrated in the 45-degree sector directly in front of the route, unable to monitor other directions. We burst in from the flanks and attacked the Vikrant at close range. ”

"Then it was besieged by six escort warships."

Hua Jianfeng smiled and shook his head. "After being attacked, anti-submarine warships and anti-submarine helicopters will first search the nearby sea area of 10 to 25 kilometers, and the anti-submarine network, which was full of loopholes, will be even looser."

Le Jiacheng thought for a moment and said: "After the attack was successful, hide under the 'Vikrant'? ”

"Those who know me will become a family." Hua Jianfeng laughed.

Le Jiacheng didn't say anything anymore, and personally stood in the position of the pilot.

Hua Jianfeng is playing with fire, but this fire is worth playing.

Having reached a depth of five hundred and forty meters, the "Swordfish" increased its speed to six knots.

As long as the "Vikrant" does not suddenly turn or change speed, after 54 minutes, the distance between the "Swordfish" and the "Vikrant" will be reduced to about 10 kilometers, and it will be located directly southwest of the "Vikrant".

The distance of ten kilometers is definitely the distance of lore.

Forty minutes later, Hua Jianfeng asked the ordnance chief to inject seawater into all four torpedo tubes.

An attack carrier is different from an attack submarine, one heavy torpedo can sink a submarine, and to sink a medium aircraft carrier with a displacement of more than 40,000 tons, at least three heavy torpedoes are needed.

"The first five, the last five, rise to the depth of the attack, control the speed!"

Because of the use of high-pressure water pumps to launch torpedoes, the maximum torpedo launch depth of the "Swordfish" was 240 meters, so it was not possible to use torpedoes at full sailing depths.

"Depth 240." After speaking, Le Jiacheng looked at Hua Jianfeng.

"Torpedoes No. 1 and No. 2 are set to wake self-guided attack mode, and Torpedo No. 3 adopts line-guided attack mode." When Hua Jianfeng gave the order, his tone was very calm.

"The attack parameters are set."

"Open the outer cover of the torpedo tube, and the first and second torpedoes are launched!"

"Bang bang" twice, two torpedoes rushed out of the torpedo tubes.

"Torpedo No. 3 launched."

With a "bang", the third torpedo was also fired.

Hua Jianfeng's gaze fell on the screen of the fire control computer.

Torpedoes No. 1 and No. 2 were in self-guided attack mode and did not occupy the submarine's fire control channel. Torpedo No. 3 used a wire-guided attack mode, occupying a fire control channel. Another fire control channel was reserved for torpedo No. 4, which remained in the torpedo tube.

After leaving the submarine, the two self-guided torpedoes first searched for advance at low speed under the control of the inertial guidance system.

The principle of wake guidance is not complicated, and when any ship is sailing, it will form a wake field with unique properties like a human fingerprint, with a length of thousands of meters to tens of kilometers, composed of force fields, electromagnetic fields and other physical fields. Relying on the relevant detection equipment and automatic control equipment, the torpedo can pursue the ship along the wake field. Because the wake field left by surface ships is more obvious, wake guided torpedoes are generally used to attack surface ships.

After about six minutes, two torpedoes detected the wake field of the "Vikrant" and automatically switched to high-speed attack mode.

As soon as the two wake self-guided torpedoes accelerated, the sonar on board the "Vikrant" immediately received the noise from the torpedo. At this time, the third torpedo also approached the aircraft carrier "Vikrant" under the control of the submarine.

"Captain, the target turns to the right."

Hua Jianfeng and Lejia were stunned for a moment, and then showed a smile.

God helped, when it came time to avoid torpedoes, the "Vikrant" actually chose to turn to the right instead of the left. Probably in order to avoid the "Vikramaditya" aircraft carrier battle group to the north, the "Vikrant" chose to turn south.

"Torpedo No. 3 switched to acoustic self-guidance mode, cut the guidance wire, turned right, speed 12, calculated torpedo hit time."

"Two minutes and twenty seconds."

"Speed 18, two-thirds right-hand drive." Hua Jianfeng did not rely on the fire control computer, and calculated the best evasion route entirely by brainpower.

"Captain, the target is starting to accelerate."

"The torpedo hit time is two minutes and thirty seconds." Le Jiacheng glanced at Hua Jianfeng and started the timer again.

"Maintain speed, right full rudder." Hua Jianfeng was calculating while regularly tapping on the countertop of the fire console.

It was necessary to take the opportunity to get close to the "Vikrant". If the "Vikrant" had not sunk immediately, the "Swordfish" could have taken refuge under the belly of the aircraft carrier. If the "Vikrant" sinks quickly, the Indian warship will first rescue the officers and men who have fallen into the water on the surface of the sea, and will not immediately search the sea area near the sinking point of the "Vikrant".

The most dangerous place is the safest place.

Suddenly, several violent explosions came, and the officers and men in the boat heard them without the sonar chief's report.

"Depth charges!" Le Jiacheng showed a look of surprise.

"Fifteen at the head, ten at the tail, speed 27, one-third right rudder." Hua Jianfeng quickly gave a new order, and then said, "The Indian Ah Sangou jumped over the wall in a hurry, and they are intercepting torpedoes with depth charges." ”

Le Jiacheng smiled and shook his head, he had just thought of this situation.

Indian warships are equipped with rocket-type deep bomb launchers, and even aircraft carriers are no exception, but the significance of the display of this weapon is far greater than the significance of actual combat.

The explosions became more and more intense, indicating that the officers and men on the Indian warship were already in a hurry.

There was a dull explosion, then another, and after a while, a third violent explosion was heard. After a while, the explosion of the depth charge also dissipated.

"Captain, the Vikrant is right above us."

"The first five, the tail five, the speed 6." After speaking, Hua Jianfeng glanced at the depth table. "540", just to the maximum safe sailing depth of the "Swordfish".

Overhead, there was a sound of the ship's hull cracking and the keel breaking.

The torpedoes directly attacked the underwater part of the battleship, and all three torpedoes exploded under the keel.

Being hit by three heavy torpedoes in a row, not to mention the medium-sized aircraft carrier of the Indian Navy, even the supercarrier of the US Navy, may not be able to withstand it
