46°15′ east longitude, south of the equator, the western waters of the Somali Sea Basin...

Under the interaction between the Somalian cold current and tropical monsoon along the coastline of the African continent, the sea area is always windy and harsh, making it the most difficult place to predict meteorological changes in the world. Before the popularization of meteorological radar, many ships would rather increase their range than bypass this sea area. However, the strong winds and huge waves on the sea surface have almost no threat to submarines sailing more than 200 meters below the sea surface, and will not have any impact on an attack nuclear submarine that does not need to float to the surface before eating all the food in the freezer.

In the command center of the submarine "Calacht" with hull number 409, Major Hua Jianfeng stared at the telegram in his hand and stayed for five minutes. Next to him, several officers wearing yellow short-sleeved shirts looked at the major captain intently, as if waiting for the captain to give orders.

More than a month ago, Hua Jianfeng led more than 100 officers and soldiers to leave Yulin Military Port on the "Calacht".

According to the combat readiness patrol plan that had been formulated long ago, after entering the South China Sea, the Calamari searched for suspicious targets in the waters near Zhongjian Island, Nanwei Island and Wan'an Beach, intimidated two dilapidated conventional submarines from Vietnam and Indonesia, and then headed to the Strait of Malacca to meet with an ocean freighter that came to cooperate.

After sailing under the belly of the cargo ship for two days and one night, the Calamari entered the Andaman Sea and encountered a P-8i anti-submarine patrol aircraft that the Indian Navy aviation company had just purchased from the United States. It conducted a three-day simulated practical exercise, proving the silent performance of the Calamari and collecting characteristic signals of the sonar buoy.

On the fifteenth day after leaving the port, the Calamari arrived at the sea off the Cochin Port at the southern end of India and began to collect passing ships, mainly various ships of the Indian Navy, especially the characteristic noise of conventional Indian Navy submarines deployed there. This time, the number one target of the Calamari class conventional submarine was the Indian Navy just obtained.

In order to strengthen the naval military strength and achieve the goal of controlling the Indian Ocean, the Indian Navy purchased six "Squid" class submarines from France in two batches. The first boat built by French company D arrived in India two months ago and entered the port of Cochin. After the completion of the Rambilian submarine base in the Bay of Bengal, the first three "Scorpio" class submarines will all go to the new nest.

Collecting the noise of new submarines in imaginary hostile countries is the main task of any naval submarine force in peacetime.

Being sent to perform this mission is enough to show that Major Hua Jianfeng, who was only thirty-three years old, had been in the army for fifteen years, served on the submarine for eleven years, and served as the captain for three years.

Hard work pays off. After waiting for nine days and nine nights, the goal finally appeared.

In the next three days, the "Calachian" not only tightly bit the conventional Indian submarine where the sea was going to sea to train, recorded the characteristic noise of the opponent and completed simulated attack training. On the third night, he followed the opponent to the depth of the periscope. He used the opportunity of charging the battery and took several precious photos with a low-light camera installed on the photoelectric periscope. During the entire operation, the Indian submarine did not find the "Calachian" close at hand.

Just as the photo was taken on the float, the Calamari received a telegram from the military communications satellite.

The telegram is repeatedly sent. It will not be terminated until the "Calachian" receives the telegram and sends a call back. This ensures that the "Calachian" can receive this telegram. This must be an extremely important telegram. Otherwise, it will not be repeatedly sent to the seas where the "Calachian" appears.

After receiving the telegram, the "Calachite" left the Indian submarine and turned to sail southwest.

After leaving the Indian Navy Air Force's anti-submarine patrol aircraft, he reached the relatively safe sea area. The Calamari released a communication buoy and then sailed southwest at a speed of 29 pm for fifty-three hours. He arrived at the designated area in the telegram to patrol the sea area.

This happened five days ago.

For five days, the Calamari kept a quiet speed of four knots, waiting for new orders. As a result, before waiting for a new order, an old friend came to the US Navy's "Houston" attacked the nuclear submarine.

The "Houston" is the 26th Los Angeles-class attack nuclear submarine, numbered SSN713, was built in the early 1980s and has been in service for more than 20 years and will be retired after a few years. After the outbreak of the "Afghan War" and the "Iraq War", the "Houston" was transferred to the Central War of the United States, with Digo Garcia as the base, and performs three combat readiness patrol missions a year.

During the three years when Hua Jianfeng was captain, the Calamari and the Houston encountered several unexpected encounters, and had long recorded the characteristic noise of the Houston. However, the Houston had never really caught the Calamari. It only noticed the existence of the Calamari several times and fled with its maximum speed of two knots.

When an old friend meets him by chance, he naturally has to go up and say hello.

As usual, the Calamari took advantage of its better silent performance and spent hours quietly walking around the buttocks of the Houston. After sailing in a constant speed with the other party, the sonar on the Calamari turned on the digital recorder and began to record the noise emitted by the Houston. The collected sound signals will be handed over to professional intelligence agencies after the Calamari returns to the base, and will conduct a comprehensive analysis to determine the status of the Houston and whether there are any large-scale improvements.

If there were no other missions, this silent tracking would last until one side was about to drink all the cold beer and had to return. For the officers and soldiers on the nuclear submarine, it often means half a month, a month, or even two months. At this critical moment, the Calamari received a telegram from the ultra-long-wave radio station.

Ultra-long-wave radios are dedicated stations specially used to communicate with submarines, especially nuclear submarines that do not float on the surface of the Shanghai area during the mission. Generally speaking, telegrams are sent to strategic nuclear submarines, rather than attacking nuclear submarines. When the captain of a strategic nuclear submarine receives such telegrams, it often means that the local area is hit by the enemy's nuclear strike, or the local security is seriously threatened, and strategic counterattacks are required to raise the strategic alert level. If it is the former, the strategic nuclear submarine will immediately launch the submarine-launched strategic ballistic missiles it carries and destroy the enemy within 20 minutes; if it is the latter, the strategic nuclear submarine must quickly enter the state of combat readiness and be prepared to launch missiles at any time.

However, this telegram was specially sent to the Caldera attacking nuclear submarine.

After sighing a long sigh, Hua Jianfeng handed the message to Captain Le Jiacheng, the deputy captain next to him, and then asked Chief Sonar: "Is the 'Houston' still in front, how far away is it from us?"

"From the front, there are less than thirty chains." "Channel" is the unit of length in nautical terms, and one chain is equal to one tenth of a nautical mile, about one hundred and eighty-five meters.

"Slow down to four knots and prepare to float on the Shanghai surface. It's time for us to change our breath!"

"Old Hua - Captain!" Le Jiacheng took two steps and shook the telegram in front of Hua Jianfeng a few times. "With this telegram, we will float in Shanghai and actively expose our identity? For three years, the "Houston" has always known that we are active in the Indian Ocean and have always wanted to understand our identity. If we float up now, isn't it equivalent to reporting our own home?"

The content of the telegram is very short, with only one approximate coordinate, a time period, and floating on the Shanghai side to welcome the orders of a special forces. At this time, the "Calachts" happened to be at the position mentioned by the telegram, and it was almost at the end of the floating time. The most important thing is that the telegram was signed by the General Staff.

"This is an order issued directly by the General Staff, and we have no choice." Hua Jianfeng did not explain much to his deputy, "Give the combat preparation order. If the 'Houston' dares to come and cause trouble, we will give it a look."

"Lao Hua..."

"Execute the order!" Hua Jianfeng took out the captain's majesty and did not give his deputy a chance to argue.

Hua Jianfeng also knew that floating in the sea where enemy boats were active, even just floating moves would be enough to expose the submarine's whereabouts. Because if a submarine wants to float in the sea, it has to blow out the sea water in the ballast water tank with compressed air, thereby generating huge noise. For submarines that regard concealment as a "talisman", exposing their whereabouts is equivalent to falling into the trap. If the "Houston" uses this to record the characteristic noise of the "Calachian", no matter which sea area the "Calachian" will go to to perform missions, no matter how quiet it is, as long as it encounters an American submarine, it will be intercepted by the advanced sonar equipment on the American submarine. After comparing with the characteristic noise data in the database, the "Calachian" can be discovered in time, and even secretly tracked the "Calachian".

However, Hua Jianfeng had no choice.

The order was issued directly by the General Staff, using a strategic communication channel, indicating that this task is very important, and even if the "Calachite" is sacrificed for this, it is not hesitant to sacrifice it.

As a soldier, Hua Jianfeng must obey orders unconditionally, even if he will die because of this.

When Le Jiacheng stood at the deputy captain's position and issued the order to evacuate the ballast tank, Hua Jianfeng walked to the side of the sonar and looked at the sonar.

"It's been under surveillance, the 'Houston' has not turned, wait... it's not good..."

"What's going on?" Hua Jianfeng's expression suddenly became nervous.

"The 'Houston' is accelerating, no... no, it is floating, and it is floating with us."

"Float? Could it be that the captain of the 'Houston' wants to know what we look like? "Hua Jianfeng's brow jumped slightly, "Continue to monitor and report any abnormalities immediately."

The sonar was not long and he immediately pressed several buttons on the sonar operation table.

Hua Jianfeng called the commander over and issued an order to install shooting data for the torpedo in advance. However, he did not rush to order the submarine's torpedo tube to be injected with water, because the "Houston" was in front and the "Calachian" was behind. If he really wanted to fight, the one who took advantage must be the "Calachian".

At this time, a red light lit up in the command center, and the "Calachite" entered a state of combat.
Chapter completed!
