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

After turning into the new channel, Hua Jianfeng stayed by the tactical command platform and drank three cups of dry coffee without sugar and milk in succession

Every move in the command center was in Hua Jianfeng's eyes, and the slightest change within a radius of tens of kilometers was under the monitoring 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, 5 Japanese submarines lurking near the "Swordfish" turned 15 minutes ago at the same time, located in the northwest direction, the two "Yushio" class submarines farthest from the "Swordfish" left the "Swordfish" surveillance range and disappeared into the vast sea, and the other three Japanese submarines were still moving at a speed of 4 "silent" and at a depth of 300 meters above the sea surface towards the Diaoyu Islands

The situation was clear, and the Japanese submarine received an order for operation

Two advanced "Xishio"-class submarines were responsible for intercepting the combat fleet and landing fleet heading to the Diaoyu Islands, while three "Qinchao"-class submarines with slightly inferior performance remained to deal with the submarines of the Republic Navy

Very simple and straightforward tactics

Hua Jianfeng had to doubt the personal ability of the Japanese submarine captain

In terms of anti-submarine combat effectiveness, whether it is a surface warship, an anti-submarine patrol aircraft, or a carrier-based helicopter, it is not as good as a submarine with advanced performance to engage an enemy with a strong submarine force, and the submarine with advanced performance should be given the anti-submarine task, instead of dealing with surface warships A few days ago, the conflict has proved that the "Qinchao" class AIP conventional submarines equipped with "Stirling" engines are not at all the opponents of the attack nuclear submarines of the Republic Navy, let alone "Swordfish" The opponent of the ship, the Japanese Maritime Self-Defense Force, not only did not learn a lesson, but also let the three "pro-tides" stay and wait for death, either the rear commander was careless and underestimated the enemy, or the Japanese submarine captain had a problem with his personal ability

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

The ground mute performance of the conventional AIP submarines of the "Xichao" class is an order of magnitude higher than that of the "Qinchao" class, and the ground noise generated during the voyage is about 95 belongings, and the "Swordfish" can only use the sideside passive sonar to find out the location of the two "Xichao" class submarines, and the distance cannot be accurately calculated, if it is not for the two "Xichao" class submarines using batteries and speeding up to the northwest waters of the Diaoyu Islands, the "Swordfish" cannot even obtain its characteristic noise

= Willing to spend a lot of money to import technology from Germany, buy production licenses, and design a model for the 212-class conventional submarines to replace the "Qinchao" class and the "Xishio" class submarines

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

The opponent of the "Swordfish" is not Japanese submarines, but two Virginia-class attack nuclear submarines

In the northwest and southwest directions of the "Swordfish", at least 2093 attack nuclear submarines and 4 modernized and modified "Yuan" class AIP conventional submarines are aimed at 3 "pro-tide", and perhaps a 095 attack nuclear submarine is waiting for the opportunity to strike nearby

According to the battle plan, the "Swordfish" was still the first to strike, and the other submarines waited for the opportunity to act

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

"There are still 5 bells" Le Jiacheng has also stayed in the command center

"Check the active sonar and torpedo again and 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 Jia Chengdu were startled, and looked at the communication officer at the same time

"Red signal!"

The captain and the co-captain were stunned for a moment, and then reacted to the fact that the "red signal" meant the beginning of the war, indicating that the "Swordfish" could be shot at any time

"Recalculate the bearing" Hua Jianfeng did not waste any more precious time, "the first five, rose to 240 depth"

"Positioning, 45,000 meters from target No. 1 and 74,000 meters from target No. 2"

"Depth 240, Speed 6"

"Idle forward, take the initiative to attack sonar ready" Hua Jianfeng propped his hands on the command platform and said to his deputy, "Prepare to cut off the towed sonar"

Le Jiacheng immediately walked to the sonar console and turned on the power supply used to urgently cut off the sonar switch

In order to accurately determine the azimuth and distance of the two "Virginia" class attack nuclear submarines, the "Swordfish" had to release a towed sonar, and it was precisely because of this that the characteristic noise of the "Xitide" class submarine was obtained, because the retraction of the towed sonar would produce obvious noise, and the "Swordfish" would definitely expose its whereabouts after using active sonar, so Hua Jianfeng did not intend to withdraw the towed sonar for the sake of the "Swordfish" worth more than 200 and dozens of the best submarine officers and men of the Republic Navy. Losing a towed sonar worth tens of millions is nothing

"Arrive at the sonic convergence point"

"Turn on the active attack sonar and prepare to irradiate the target"

Because of the fact that the two Virginia-class attack nuclear submarines were to be launched separately, the Swordfish had to stop at the intersection of sound waves

"Charge up, active attack sonar ready"

Hua Jianfeng hesitated a little and said: "Tactical detection mode, irradiate 2 targets"
