At the bottom of a trench at a depth of about 240 meters, the 901 boat was lying there silently and motionless like a huge deep-sea monster.

"Distance 10730, azimuth 319, approaching!" sonar officer Wang Gang gestured, lowered his voice and reported to Ning Yuanhang.

From the direction where the target was at the moment, Ning Yuanhang could be sure that the Los Angeles attack nuclear submarine of the US Navy was advancing towards this sea area at high speed.

As the saying goes, knowing oneself and knowing one's opponent is invincible.

For nuclear submarines, the maximum speed in the water of the Dahan-class is 29 knots, which is not ideal in getting rid of the attack of high-speed torpedoes launched by the enemy.

Since the navies of various countries have no effective means of intercepting torpedoes by ships evading torpedo pursuit, they generally adopt high-speed escape + counter-jamming. Of course, if you get caught by a wake homing torpedo, you can't interfere with it. In addition to escaping from the torpedo range, it can only be seen if the Dragon Lord takes special care of you.

In the case of a submarine to a submarine, the only way to escape at high speed is to prolong the time of being caught up by the torpedo, and then use jamming means to consume the range of the torpedo. However, compared to the 55-knots and 46-kilometer range of the MK48 torpedo equipped with the Los Angeles-class attack nuclear submarine, the 29-knots speed of the Dahan-class is a bit too slow.

Since he knows where his shortcomings are, Ning Yuanhang will certainly not use his shortcomings to overcome the enemy's strengths.

The biggest advantage of the Dahan class is that it is the first enemy to be discovered, and which one is stronger to read novels on mobile phones? The mobile phone reading network is locked on to the enemy first, and then the advanced guidance function of combining the Tempest II torpedo wake self-guidance, line guidance, and sonar guidance multi-layer guidance, supplemented by an absolute underwater speed of nearly 200 knots, is the first to strike.

"Prepare for torpedo navigation!" Ning Yuanhang calmly gave an order: "All units are ready to attack, prepare for torpedo launch!"

Deputy Captain Feng Dahai reacted quickly: "Adjust the azimuth 319, two cars into one, prepare torpedo navigation, and calculate the launch plan!"

His eyes were fixed on the radar screen, which kept flashing a rapidly approaching cursor. Ning Yuanhang decisively gave an order: "Send out active sonar!"

Feng Dahai and all the personnel in the boat were taken aback by Captain Ning's order. Because when you send out active sonar, it also means that you will also be informed by the other party.

Ning Yuanhang saw the worries of his comrades-in-arms, and said with an indifferent smile: "With the arrogance of the Americans, they will definitely regard our action as an inconsequential little warning. ”

……

In the night sky, a "DY20-16H Poseidon Eye" land-based ground surveillance and control early warning aircraft painted in sky gray and sprayed with the dark military insignia of the Eastern Union Air Force. Cruising and circling at a low altitude of 3,500 meters about 300 kilometers northeast of the Pauk Strait.

This DY20-16H Poseidon Eye early warning aircraft is directly using the fuselage of the Huaxia Y10B commercial aircraft plus a rotating radar module and a land-air refueling module, with a radar diameter of 9.1 meters and a middle thickness of 1.8 meters, supported by two 4.2-meter support frames. The TKAN/APY-16 horizontally rotating radar can monitor the space between the ground and the stratosphere, including the water surface, and four engines can provide one megawatt of power to the radar.

The Doppler pulse radar used has a radius of more than 400 kilometers and can detect high-altitude and low-speed flying objects, and the horizontal pulse wave has a range of 650 kilometers to detect air vehicles at medium and low altitudes. The sub-supervised radar subsystem in the radar group can further identify and mark the target with friend or foe identification. and eliminate the clutter caused by ground objects.

The Eye of the Sea God is an advanced land-based large early warning aircraft specially developed by Yang Weiping for the Navy, and two of them have already joined the service of the Eastern Union Navy. It is subordinate to the "Poseidon" electronic early warning aircraft fleet of the First Fleet Aviation Wing of the Eastern Union Navy, and its main task is daily combat readiness duty patrols.

However, at this time, this "DY20-16H" is responsible for the early warning and cruising mission of the First Fleet's sea trial exercise, and also serves as a communication relay station between the 901 boat and a special operations team deep in the mountains of northern Sri Lanka.

Since the 901 boat had lost contact with the fleet for 27 hours, Yang Weiping had already ordered Shi Zhenhai to let all the anti-submarine planes that went to sea with the fleet take off to conduct a carpet search in the surrounding waters. All the information returned from the search will be summarized and analyzed by this Poseidon Eye and then transmitted back to the fleet command center.

The WZ-10H armed anti-submarine helicopter piloted by Liu Xing and Wang Hongbing also participated in the search without exception, and the area they were responsible for was not too far from the trench where the 901 boat was hiding.

And at the moment when the 901 boat emitted an active sonar. It was immediately discovered by this WZ-10H anti-submarine helicopter, which was engrossed in searching.

The experienced Wang Hongbing immediately followed the direction of this wave of active sonar. Soon, the SSN699 "Jacksonville", which was traveling at a high speed of 200 meters underwater, was caught by the sonar crews of WZ-10H.

"Found the 901 boat! Bearing 241, distance 500, it is targeting a US submarine with active sonar!" The sonar officer obviously shouted with some excitement: "The results of the signal comparison analysis show that it is a Los Angeles-class attack nuclear submarine of the US Navy!"

"It's a big deal!" Liu Xing quickly responded: "Red soldier, you quickly call the 901 boat." I need to report this incident to the command center immediately!"

Almost at the same time, inside the USS Jacksonville attack nuclear submarine SSN699 of the US Navy, the sonar officer cheered happily and shouted to Crowle: "Found it, azimuth 429, distance 8000." It didn't move, it seemed to be sitting on the bottom, and it could be confirmed that it was a submarine!"

"Confirm again!" Robinson quickly rushed to the display console and said in a deep voice: "Have you judged what kind of ...... the other party is?"

"The system analysis is still ongoing. The intelligence officer replied helplessly: "Wait, the result is out, it's the Dahan-class attack nuclear submarine of the Eastern Union Navy!

"How deep is that sea area?" Robinson, who was obviously no stranger to the Eastern Union Navy's Dahan-class attack nuclear submarines, asked aloud with a little nervousness.

"It's a shallow sea area, with an average depth of 269.45 meters, which belongs to the high seas......" Staff Officer Crow answered very competently and in a timely manner.

Before Claure's words fell, he suddenly heard the sonar officer scream and shout: "High-frequency active sonar! Azimuth 303! Repeat, active sonar, distance 5000! Not good, there are anti-submarine aircraft, we have been discovered, and there is a wave of active sonar ......."

"Where are we now!" Robinson asked in a deep voice.

"340 nautical miles southeast of the Pauk Strait, in the open sea. "The intelligence officer hurried to report.

At the same time, it was locked by the active sonar emitted by the opponent's attack nuclear submarines and anti-submarine helicopters, which made the hearts of all the US Navy officers and men on the SSN699 "Jacksonville" jerk up. Damn! The Oriental Union Navy is too arrogant! This sea area is very close to India's territorial waters.

Discovered by anti-submarine helicopters, this also means that the SSN699 "Jacksonville" has also entered the line of sight of the aircraft carrier battle group of the Eastern Union Navy that is conducting exercises.

Prior to this, the Indian Navy's anti-submarine patrol aircraft had just reported that the area was safe. Damn Indian fools here! The people of the Eastern Union have come to their doorstep to conduct military exercises, and they actually say that it is safe! How did the Oriental Union submarine evade the search of the Indian Navy's anti-submarine patrol planes?

The atmosphere inside the SSN699 "Jacksonville" suddenly became tense. Active sonar, which means that the other party has already discovered them first, and it is very likely that the other party is already preparing for torpedo launch at this time. And for submariners, no one wants to die silently in the depths of this icy sea, and even their bones cannot be found. Therefore, this kind of active sonar attack is the most frightening thing for the submarine officers and men.

"Don't be nervous!" Robinson took a deep breath and said calmly, "If the Oriental Union people dared to attack, they would have fired a torpedo at this time, instead of issuing an active sonar to warn first." ”

"Your Excellency Captain Robinson, I'm still ready to launch torpedoes and missiles!" Claure said very sternly, "Besides, I'd better make a U-turn." ”

"What are you doing in a daze! Didn't you hear what Staff Officer Claure said? Execute the order!" Robinson roared and roared, "Immediately use the public channel to establish a dialogue with the Eastern Union Navy and report to Washington and the Pentagon!"

……

With the huge iron-gray bow of the ship, cutting through the waves glittering with phosphorus and phosphorus moonlight, the guided missile destroyer "Bai Qi" was heading at high speed at a maximum speed of 35 knots towards the accident site reported by Haiyan 3-101.

After receiving an emergency message from Liu Xingtong, Yang Weiping immediately made a decisive decision and ordered all the combat ships participating in the live-fire sea trial exercise to circle the sea area where the 901 boat was located in a fan-shaped area.

At the same time, the carrier-based aircraft on the Baron John Young also quickly lifted 12 Qiang-5 B2-D light carrier-based fighter-bombers, and cooperated with the eight J-15A that took off from the North Andaman Island Air Base to escort the fleet, and shared the number of the DY20-16H Poseidon Eye early warning aircraft to form an air encirclement, and on the premise of ensuring the safety of all the crew members of the 901 boat, they fought with the momentum of a group of lions and rabbits, and tried to catch the Los Angeles-class attack nuclear submarine of the US imperialists.

If it was a submarine from India, Indonesia, Singapore and other ASEAN countries, Yang Weiping would have ordered the 901 boat to launch a torpedo to sink the other side.

However, this is a Los Angeles-class attack nuclear submarine of the US Navy.

Yang Weiping knows very well that the US imperialist military satellites in space must have locked all the sea areas of the US submarine, and at the same time, they are continuing to track and monitor the aircraft carrier formation of the Eastern Union Navy.

Under such circumstances, if this Los Angeles-class attack nuclear submarine is sunk, it will definitely completely anger the US Government.

However, if this Los Angeles-class attack nuclear submarine is allowed to swagger away, won't it allow the US imperialists to slap the face of the Eastern Union Navy......? I1292
