Chapter 1255: Start anti-passback

111 ship.
The door of the helicopter hangar at the rear was opened, and several people shouted and pushed the helicopter out of it.
The Sea Hawk helicopter is the navy version of the Black Hawk. After Han Guo bought four Kidd-class destroyers, it also introduced this Sea Hawk helicopter. After a period of operation, this helicopter uses its excellent performance. Completely conquered the navy, it was amazing.
It is a pity that the Eagle country does not agree to export the production line, otherwise, Han will definitely produce a large number of Sea Eagles. Now, the further order of naval helicopters can only be expected to cooperate with the Noodle country's A109 helicopter.
The crew stepped into the cockpit. The pilot Liu Yong sat in his seat, flipping the switches one by one, and the engine on the top heard the unique whistling sound.
"Startup was successful."
Since the start of the engine, there is almost no need for a second time to start the engine, almost always a success.
"Haiying 1, ready to take off, request to take off." Liu Yong shouted over the radio.
"Take off immediately for anti-submarine operations!" A voice came from the headset.
Following the sound, his left hand gently pulled the total moment, and the whistling sound of the propeller on the top became sharper. The propeller stirred the airflow, lifted the helicopter, and slowly left the landing platform.
Then, the second Seahawk was also pushed out. This large warship can carry two anti-submarine helicopters at the same time, and its anti-submarine capability is greatly improved.
The helicopter climbed slowly, and the sea below became huge. He pushed the joystick and the helicopter flew towards the target sea area.
This is a joint anti-submarine exercise, and the target is an underwater nuclear submarine!
While the Seahawk was slowly flying towards the target waters, the fan-hunting anti-submarine aircraft that had been patrolling in the sky had already taken the lead and flew towards the target waters. Its fuselage deflected and its huge belly was in the sky. An arc was drawn in the middle, the jet engine roared in the sky, and the fuselage had completed this turn.
In anti-submarine warfare, fixed-wing aircraft have great advantages over helicopters. The first is speed.
The drag of helicopters due to the overhead rotors is generally only about 300 kilometers per hour. Under the current situation, it takes an hour for them to reach the target sea area. In contrast, the current anti-submarine aircraft hunting The sky can easily exceed the speed of 700 kilometers, it only takes half an hour.
"Attention, prepare the sonar buoy!"
Compared with anti-submarine helicopters, fixed-wing anti-submarine aircraft also have a lot of space in the body. Now, after receiving the order, an operator wearing a helmet at the back of the body presses buttons one by one.
Below the rear fuselage, a hatch automatically opened, revealing the rocket launching nest-like equipment, and the tubes were all sonar buoys.
"Attention, prepare to throw the first batch of sonar buoys!"
"Received! Start throwing!"
"Hum." The first sonar buoy came out of the launcher. Its tail opened a small parachute and fell toward the water. Then, it entered the water and went down.
"Puff!" When the sonar buoy entered the sea water, there was a splash. This sound is so clear. It pushes the sea water and continues to propagate forward until it reaches the sonar of the Victor-class submarine sailing underwater. On the ball, pushing the sonar ball, it made a soft noise.
Inside the submarine, there is no difference between day and night, all of which are timed by the submarine clock.
Under normal circumstances, it is an eight-hour work system. The crew work three shifts, eight hours work, eight hours rest, and eight hours entertainment.
Now, captain Ivanov sleeps in his captain’s room. The underwater tracking game sometimes lasts for the last month. He has to save his energy and wait until the other party launches a missile. Wake yourself up.
He slept soundly, because he had not yet reached the time to routinely communicate with his superiors, so he would not know that the Chinese Navy had completed the underwater launch experiment of ballistic missiles, and they had finished it.
Now, he was still sleeping, and in the sonar room next to him, the sonar crew frowned when he heard this ordinary sound.
What is this sound? It's the sound of something falling into the sea!
what? This is a lot, the most terrifying, of course, is the sonar buoy.
Could it be such a thing?
No, you are tracking the submarine in front of you, and that submarine is still sailing steadily, without noticing your pursuit. Now, above your head, how can the sonar buoy fall?
"Puff through, puff through." The voice came from the ground all at once, is there more than one?
The sonar has already felt something wrong. If there is only one, it can be explained as an accident. However, if the sound keeps coming, it is more likely to be a sonar buoy. Could it be that you have been discovered?
This is impossible. There is no sound of surface ships nearby, no other party’s fleet, how did the opponent’s helicopter fly over?
Suddenly, the sound in the headset came like a tsunami. This time, he was agitated and shouted loudly: "Quick, wake up the captain, the other submarine is accelerating!"
In front, 320.
Captain Lei stood on the control tower, looked at the order he had just received, and said: "Attention, all boats, sail at full speed!"
Following his command, the marine engineers immediately mobilized the power to the maximum, 480 batteries. At this moment, all were activated. The surging electricity was transmitted to the tail motor, which was spinning happily. Stirring the sea, making a rustling sound, the submarine of more than two thousand tons began to accelerate!
Underwater navigation all relies on batteries. The distance of the navigation is related to the speed. At a speed of 3 knots, you can sail for several days and nights. If it becomes full speed, all the electricity is consumed in that hour.
At the same time, when sailing at full speed, the submarine's noise will become very loud and will be easily detected by the opponent's sonar equipment.
The entire No. 320 submarine, like a powerful fish underwater, began to accelerate.
Ivanov rubbed his sleepy eyes and came to the control tower. When he learned that the submarine in front had started to accelerate, his eyes flashed brightly: "Accelerate, follow acceleration, and catch up!"
The opponent has accelerated, it is about to launch, rush to the launch position, right? Of course we have to catch up!
The opponent's conventional submarine can run as fast as 20 knots underwater, but our own is a nuclear submarine. It can easily reach 30 knots underwater, and it is sailing for a long time. Now, we have to catch up!
Of course, this chase is destined to be thrilling.
Underwater high-speed chasing, if you don't pay attention, you will collide, but for the submarine soldiers of the bear country, they have never known what is dangerous.
