The Gaoxin-6 anti-submarine patrol aircraft is very recognizable. It has a fat chin (downward-looking search radar), a long tail (magnetic detector), and its strange appearance is impressive.
This aircraft is based on the Yun-9 tactical transport aircraft, also known as the Yun-9 anti-submarine patrol aircraft. The Yun-9 was developed from the Yun-8. The earliest anti-submarine patrol aircraft was developed on the Yun-8 platform. , the Gaoxin-6 anti-submarine patrol aircraft will therefore be called the Yun-8Q anti-submarine patrol aircraft.
Using a six-blade propeller, the Gaoxin-6 anti-submarine patrol aircraft has excellent flight performance and a large combat radius.
It is speeding towards the target sea area.
Li Hai circled and flew over the patrol formation. He was responsible for guarding the nearby airspace, while Dang Weimin was responsible for searching the sea. No. 165 and No. 166 have formed a pincer shape and are outflanking the target sea area, but the sonar has lost the target, and the target has undoubtedly woken up.
180 meters underwater, in the dark and sloppy water, a slender man-made monster is suspended, traveling at a speed of 3 knots, and it is almost invisible to move.
This is a Virginia-class attack nuclear submarine belonging to the simulated Blue Army Pacific Fleet. This is a big guy with an underwater displacement of up to 7,800 tons. The silent level of this type of submarine is equivalent to that of the "Seawolf" class attack nuclear submarine, which is known as the world's quietest submarine, and the former uses a more advanced submarine electrical system.
The Virginia class will replace the Los Angeles class.
However, the Virginia class prefers offshore operations and retains its far-sea combat capabilities.
This Virginia-class attack nuclear submarine is the USS Colorado. It was commissioned nine months ago. It is a brand-new submarine. This is the first time it has carried out a long-distance mission.
The sound heard by the old sonar commander of Destroyer No. 165 came from the turn of the Colorado more than ten minutes ago. After discovering the unusual movements of No. 165 and No. 166, the Colorado judged that their whereabouts had been exposed, and then decisively slowed down to 3 knots.
The sound of the slowly submersing Colorado was almost lost in the background noise of the ocean, making it difficult for No. 165 to capture any traces of the boat.
Why did the Colorado make a 180-degree U-turn when it was so close? Because there is a submarine underwater and it occupies a favorable position...
This submarine is the Great Wall, and its captain is Zhao Yunlong, an acquaintance of Li Hai. The Great Wall HMS A, which is testing the new AIP power system, has excellent quiet performance and has a home field advantage. It is familiar with the conditions of submarine mountains and hydrological conditions.
The Great Wall A was conducting a silent submersible test in this area when it suddenly discovered that an unknown submarine was approaching the patrol formation. Zhao Yunlong made a prompt decision and quickly occupied a superior attack position behind the target, and his sonar locked onto the Colorado.
This was Zhao Yunlong's first encounter with a Virginia-class attack nuclear submarine. He was confused for a moment as to what kind of submarine it was. However, he followed the rules and immediately launched an attack sonar to the Colorado to warn him to leave the waters because the Colorado was patrolling far away. The formation is too close.
The Colorado was startled, turned around in a panic, and pointed its bow at the Great Wall. It was during this U-turn that the sonar of destroyer No. 165 captured clues of the Colorado.
The Great Wall's advantage was due to some luck. Zhao Yunlong and the others were sailing at a speed of 5 knots, while the Colorado approached the patrol formation at a speed of 12 knots. Zhao Yunlong immediately discovered this somewhat reckless Foji. Nia-class nuclear attack submarine. When the Colorado was attacked by sonar, it responded quickly. When its speed was reduced to 2 knots, it disappeared from the Great Wall's perception range.
At this time, Zhao Yunlong made a judgment - the target must not be Los Angeles level. He was too familiar with the Los Angeles class and could never achieve such a level of silence at this distance.
Zhao Yunlong suspected that it was the Sea Wolf class.
Among the submarines he had encountered, only the Seawolf class could do this.
At this time, the situation of the Great Wall Armor was not very optimistic. Zhao Yunlong's use of attack sonar (active sonar) meant that he was also exposed. Zhao Yunlong reduced the speed to 2 knots and turned slowly. The bow of the boat was always pointed at the Colorado, but he could only roughly judge the position of the Colorado.
Underwater competition is sometimes like a blind man touching an elephant. He has to make a decision even when he is not completely sure.
The Great Wall A also faces a problem - the possibility of accidental attack from its own ships. However, the solution is also simple, surface communication identification. Zhao Yunlong's actions have nothing to do with the large-scale drill. Unless the drill headquarters inquires with the ship commander or submarine command, it will not know the whereabouts of the Great Wall.
Zhao Yunlong decided not to contact him for the time being. He knew that under normal circumstances, the surface formation would not launch an attack. The question now is, what can he do to cooperate with destroyers No. 165 and No. 166 on the water to drive away the Colorado.
The whereabouts of destroyers No. 165 and No. 166 have been monitored by the Great Wall. The sound of these two old destroyers is really too loud. In the Great Wall, which has the most advanced sonar system, it is like two rumbling diesel engines ringing in the ears.
Zhang Zhengdong and the others did not discover the Great Wall No. 1, which added a bit of uncertainty to this mutually invisible struggle.
Li Hai hovered over the destroyer No. 165, waiting for the arrival of the Gaoxin-6 anti-submarine patrol aircraft.
The command cabin of the Great Wall was so quiet that you could hear a pin drop. Everyone was holding their breath and waiting for news from the sonar room.
Zhao Yunlong crossed his arms and closed his eyes slightly, his mind spinning rapidly. Standing next to him is the staff sergeant, First Class Sergeant Wu Zhiguo, who has assisted five captains.
The Great Wall Armor stopped turning and maintained an extremely slow speed of 2 knots. The Colorado had completed its turn, and its bow was facing the bow of the Great Wall.
"Old Wu, do you think the target will change the diving depth?" Zhao Yunlong asked in a low voice.
Wu Zhiguo shook his head slightly, "It's hard to say."
The diving depths of the two boats are the same. If they don't change, they will collide sooner or later. The Great Wall Armor has already actively launched an attack sonar, revealing its position. The Colorado has not used attack sonar, meaning it can only detect the noise made by the Great Wall. However, the noise levels of both boats are now so low that they are almost lost in the background of the ocean.
"Launch attack sonar." Zhao Yunlong decided.
Wu Zhiguo did not hesitate and quickly issued the order.
The active sonar located at the bow of the boat worked and emitted active sound waves 120 degrees forward. The sound waves hit the Colorado 8 nautical miles away, and a clear "clang" sound could be heard from the sonar headphones.
There was another panic inside the Colorado. Captain Rosen knew very well that the other party wanted to force him to the surface, which Rosen could not accept. Rosen believes that Virginia-class attack submarines are the most advanced submarines in the world, and there is no way he would admit defeat in the face of two old destroyers and one conventional submarine.
"Dive to 220 meters! Advance at full speed!" Rosen did not fight back with an attack sonar, but chose to accelerate towards the rear of the Great Wall.
Seeing that the Colorado gave up hiding, Wu Zhiguo excitedly shook his fist and said, "This guy can't sit still."
Zhao Yunlong smiled and said, "Let him go and follow him. Old Wu, what kind of boat do you think it is?"
"It should be an unfamiliar model, captain, we may be lucky." Wu Zhiguo said.
Zhao Yunlong smiled tacitly.
The only stranger in the simulated blue army is the Virginia-class nuclear attack submarine.
The sonar room quickly came over to report that the sonar signature of the Colorado was placed in front of Zhao Yunlong. After reading it carefully, Zhao Yunlong couldn't smile from ear to ear. It no longer mattered whether she was exposed or not. The Great Wall Armor could now stalk the Colorado with great arrogance.
but!
Zhang Zhengdong doesn’t think so!
His mission is to stop the Colorado and prevent it from heading towards the no-navigation zone.
Zhao Yunlong guessed this, so he decisively released the communication buoy and sent a message to the No. 165 destroyer where Zhang Zhendong was located - Brother, I am one of my own, don't shoot!
After receiving the message, Zhang Zhengdong was obviously stunned for a moment, and then smiled knowingly. After confirming the location of the Great Wall, Zhang Zhengdong could concentrate on pursuing the Colorado.
The Colorado, which was advancing at full speed, was quickly captured by the sonar of destroyer No. 165. Zhang Zhengdong ordered it to advance at full speed. The old destroyer No. 165 easily reached a speed of 30 knots and sailed side by side with No. 166.
After receiving Zhang Zhengdong's intelligence report, Li Hai immediately rushed to the front and used a combination of airborne radar sea search and visual search to stand ready, waiting for the Colorado that might be forced to resurface in an emergency.
The multiple anti-submarine rocket launchers on the bow deck of the No. 165 destroyer were ready. After Zhang Zhengdong received the consent of the exercise headquarters, he ordered the launch of multiple anti-submarine rockets into the waters near the Colorado.
Anti-submarine rockets designed to attack submarines are low-cost, low-tech, and reliable in performance. For a long time, they have been an essential anti-submarine weapon for warships of various navies. With the development of submarine technology, the combat effectiveness of anti-submarine rockets has become increasingly unable to keep up, and they have gradually withdrawn from the stage of history.
However, the Type 054A frigates heavily equipped by the People's Navy are still equipped with new models of anti-submarine rocket launchers, indicating that this anti-submarine weapon still has a place in anti-submarine equipment.
The two anti-submarine rocket launchers on the front deck of the No. 165 destroyer fired "swish, swish, swish", and the scene was spectacular. In the past many years, the most eye-catching scene in the exercises of our People's Navy is the launch scene of the anti-submarine rocket launcher. It is a necessary propaganda scene. It is the same as the aerial fire in the Air Force and the same as the long-range fire in the Army. the same……
The people's army will never be able to deal with rockets in this life.
Zhang Zhengdong was very measured. He fired all the rockets in the waters near the Colorado, which did not cause any damage and also served as a warning.
Li Hai watched with great interest and raised his camera to take pictures from time to time.
The Gaoxin-6 anti-submarine patrol aircraft arrived. After establishing contact with Li Hai, Li Hai gave up the airspace, and the Gaoxin-6 anti-submarine patrol aircraft began to drop sonobuoys underwater.
The Colorado was caught in a dragnet.
Rosen couldn't figure out why the situation suddenly became so bad, but he didn't intend to admit defeat. He was sure that the other party did not dare to do anything to him, and completely forgot the previous lessons.
"Yaoguai, Patrol No. 1, continue the drill. The suspicious submarine will be handed over to the patrol aircraft and Patrol No. 2." The drill headquarters suddenly issued an order.
At this time, the exercise headquarters had learned that the USS Great Wall was hoisted onto the USS Colorado, and that there was a Gaoxin-6 anti-submarine patrol aircraft in the air, plus the destroyer No. 166, making it impossible for the USS Colorado to escape. The exercise headquarters believes that there is no need to affect the exercise plan.
The J-10A team and the J-11B team have completed live-fire firing. All six red target drones were shot down. The live-fire firing of the air combat unit was successfully completed. At this time, the two remote-controlled target boats released by destroyer No. 165 were still sailing according to the established route.
The operator who controls the remote control boat is a rookie, a college recruit. Although he is new, his skills are good. But he was a new recruit after all. After the battle alarm sounded, he was a little flustered and distracted. He didn't notice that the remote-controlled boat was sailing to the sea in front of the Colorado according to the planned route.
Maybe there was an oversight in the collaboration between departments, or maybe it was for other reasons, but no one pointed out the problem with recruit Danzi—he should have adjusted the course of the remote-controlled boat in time.
However, some people believe that it is understandable that recruit Danzi has only been in the army for one year and does not have sufficient ability to adapt to situations.
Li Hai, who was the executor of live-fire shooting, did not notice this problem. He reluctantly opened the distance and entered the attack route, successfully locking the two remote-controlled boats.
Li Hai looked at the remote control boat circled by the aiming ring and wondered. It didn't make sense that the detection of moving targets was more sensitive than the detection of fixed targets.
"In the South China Sea, Yaoguai has locked the target and requested an attack. It's over." Dang Weimin, as the weapons operator, reported to the exercise headquarters.
"Yaoguai can proceed as planned. It's over." the drill headquarters replied.
At this time, Li Hai said, "I'll do it."
"Understood." The party sent a launch button to the people.
In the operation center on destroyer No. 165, the commander discovered a problem with the route of the remote-controlled boat and immediately instructed the recruit Danzi: "That's the anti-submarine mission area! Adjust the course quickly!"
The new recruit Danzi was startled and immediately scrambled.
As a result, a mistake was made while busy. The two remote-controlled boats turned to the wrong course. Instead, they accelerated and invaded the anti-submarine mission area, which was the route of the Colorado.
At this moment, Li Hai pressed the launch button. At this time, the first air-to-surface missile should detach from the pylon and leave the carrier aircraft. Li Hai did feel the fuselage suddenly loosen. He pressed the launch button again. The fuselage suddenly loosened again.
"Wrong, wrong, wrong! What you shot was a guided bomb!" Dang Weimin suddenly shouted.
Li Hai was shocked. He looked down and was horrified to see two 1000KG-level guided bombs leaving the plane!
Wrong line?
"Yaoguai report! Wrong firing of ammunition! Repeat, Yaoguai fired wrong ammunition!" Li Hai reported quickly.
Two guided bombs without activated fuses fell towards the aiming point under the force of inertia. The fuse was not activated, and the two guided bombs were just two lumps of iron. Obviously, there was no way to hit the fast-moving remote-controlled boat.
There is no error in the power connection of the pylon. Li Hai and Dang Weimin have checked it, and Li Yuanchao's maintenance team has also checked it repeatedly. Whether launching air-to-surface missiles or guided bombs, the external safety is manually released before takeoff, and the fuze safety is activated by the pilot before launch. There is no problem with this program. The information displayed on the tactical screen is that the fuzes of the two air-to-surface missiles have been successfully activated.
But what was launched was two guided bombs, so there was only one reason. There was something wrong with the relevant wiring inside the fuselage, and the wiring was wrong.
