To the east of the Yu Island, below the sea surface about 50 nautical miles

After entering the new channel, Hua Jianfeng stayed by the tactical podium and drank three cups of dry coffee without sugar and milk.

Every move in the command center is in Hua Jianfeng's eyes, and the slightest change within a radius of dozens of kilometers is under the surveillance of the "Swordfish".

Half an hour ago, Hua Jianfeng received the latest news that the Foreign Minister officially announced the exercise of sovereignty over the Diaoyu Islands

25 minutes ago, the 5 Japanese submarine lurking near the Swordfish turned 15 minutes ago at the same time. It was located in the northwest direction. The two "Xi Chao"-class submarines that were farthest from the Swordfish left the surveillance range of the Swordfish and disappeared in the vast sea. The other three Japanese submarines were still at a "silent" speed of 4 and advanced towards the Diaoyu Islands at a depth of 300 from the sea.

The battle situation is clear, and the Japanese submarine received the combat order

Two advanced "Xichao" class submarines are responsible for intercepting combat fleets and landing fleets heading to the Diaoyu Islands. Three "Qichao" class submarines with slightly poor performance stay to deal with the submarines of the Republic's Navy.

Very simple and very direct tactic

Hua Jianfeng has to doubt the personal abilities of the Japanese submarine captain

The best weapon to deal with submarines is the submarine itself. In terms of anti-submarine combat effectiveness, whether it is a surface warship, anti-submarine patrol aircraft or a carrier-based helicopter, it is not as good as a submarine with advanced performance and fighting enemies with strong submarine forces. The advanced performance should be allowed to undertake anti-submarine missions, rather than dealing with surface warships. The conflict a few days ago has proved that the "Qi Tide" class AIP conventional submarine equipped with the "Sterling" engine is not the opponent of the Republic's Navy's attack nuclear submarines, nor is it the "Swordfish" opponent, not only did the Japanese Maritime Self-Defense Force not only did not learn lessons, but also allowed the three "Qi Tide" to stay and wait for death. If it were not for the commander of the rear to carelessly underestimate the enemy, it would be that the Japanese submarine captain had a problem with the personal ability of the captain of the Japanese submarine.

Hua Jianfeng also has to admire the advanced technology of the Germans

The silent performance of conventional submarines using hydroxide ion membrane fuel cell is improved by one order of magnitude compared with the "Qinchao" class. The ground noise generated at 4 o'clock is around 95 beta. Without towing sonar, the "Swordfish" can only use the side passive sonar to find out the location of the two "Xichao" class submarines cannot accurately calculate the distance. If it is not for the two "Xichao" class submarines to use batteries, the "Swordfish" can even obtain its characteristic noise.

=Shede spent a lot of money to introduce technology from Germany, purchased a production license and designed it to replace the "Xichao" class submarine in the "Qinchao" class

In the past half an hour, Hua Jianfeng only did one thing: record the characteristic noise of the "Xichao" class submarine

The opponent of the "Swordfish" is not a Japanese submarine, but two "Virginia"-class attack nuclear submarines in a lingering state

There are at least 2093 attack nuclear submarines and 4 modern modifications in the northwest and southwest directions of the Swordfish. The Yuan-class AIP conventional submarines are aimed at three "female tides". Perhaps there is still a 095 attack nuclear submarine waiting for the opportunity to take action nearby.

According to the combat plan, the "Swordfish" is the best-performing submarine to take action first.

After looking at the time displayed in the upper left corner of the screen, Hua Jianfeng looked at his deputy

"There are 5 minutes left" Le Jiacheng has also stayed in the command center.

"Re-check the active sonar and torpedo to confirm the situation"

"Active sonar ready"

"Torpedo ready"

Hua Jianfeng closed his eyes and took a long breath

"Report, Latest Telegram"

Hua Jianfeng and Le Jiacheng were both shocked and looked at the communication officer at the same time.

"Red signal!"

The captain and the deputy captain were both stunned, and then they realized that the "red signal" meant that the war began, indicating that the "Swordfish" could take action at any time.

"Recalculate the orientation" Hua Jianfeng did not delay his precious time, "first five, rising to 240 depth"

"The positioning is completed, 45,000 from target No. 1 and 74,000 meters from target No. 2"

“Depth 240, speed 6”

"Idge forward at a speed and take the initiative to attack the sonar." Hua Jianfeng supported his hands on the podium and said to his deputy, "Prepare to cut off the drag-and-drop sonar."

The Lejia immediately walked to the sonar console and turned on the power supply for emergency cut off the sonar switch.

In order to accurately determine the orientation and distance of the two Virginia-class attack nuclear submarines, the Swordfish had to release a tow-drop sonar. This is why it obtained the characteristic noise of the Xichao-class submarine. Because the retraction of the tow-drop sonar will produce obvious noise, the Swordfish will definitely expose its whereabouts after using active sonar. Therefore, Hua Jianfeng does not intend to retract the tow-drop sonar. In order to lose a tow-drop sonar worth more than 200 yuan and dozens of the best submarine officers and soldiers of the Republic Navy, it is nothing to lose a tow-drop sonar worth tens of millions.

“Arriving at the sound wave convergence point”

"Switch on the active attack sonar power supply and prepare to illuminate the target"

Because it is necessary to launch sound waves to two Virginia-class attack nuclear submarines, the Swordfish must stop at the intersection of sound waves.

"After charging, take the initiative to attack the sonar and be ready"

Hua Jianfeng hesitated for a moment and said, "Tactical detection mode, illuminate 2 targets."
