Red Soviet Union

As an advanced Soviet nuclear submarine, the equipment of the 949-class nuclear submarine is very advanced, and in the underwater world that relies entirely on listening, the 949-class is also fully equipped. It has a total of four types of sonar, including "shark gill" type active/passive Medium and low frequency search and attack hull sonar, "Shark Rib" passive low frequency broadside array sonar, "Rat Ming" active high frequency attack hull sonar, "Pyramid" passive VLF trailing line array sonar.

These sonars can provide full frontal and side views. However, like all submarines, the 949 cannot detect the situation directly behind itself. Even if the sonar is deployed there, the noise of the propeller at the tail stirring the sea water will not be detected. It will make the 949 level unable to receive any sound from the rear, all noise.

This is a congenital defect of submarines, which cannot be overcome. Therefore, Soviet submarines at the peak of the Cold War confrontation will adopt a common tactic. Americans call this tactic the stupid Yankee, and another name is the crazy Ivan!

Since neither the bow sonar nor the broadside sonar of the submarine can detect the sound source at the rear of the submarine, then, in order to hear the sound of the tail, there is only one simple way: turn!

If it is an early submarine with only bow sonar, the steering will be 180 degrees. A sharp turn will make the rear tracker unable to respond, and a 180-degree turn may also make the rear tracker unable to respond. Rush to the front, thus becoming the prey. You must know that most of the early torpedoes were tail-following, and whoever occupied the tail-biting position would win.

But now, after equipping the broadside sonar, as long as the submarine turns 90 degrees, it can use the broadside sonar to aim at the original rear for observation! In order to prevent the rear from reacting, the steering must be fast, so a sharp turn at full speed is the most correct choice!

The reason why this action is crazy is that there is no tracking submarine behind it. If there is, it is easy to collide underwater. This is a precedent. Ten years ago, the US SSN-639 "wrasse" The USS nuclear submarine collided with the Soviet Echo 2 nuclear submarine, but fortunately neither side caused casualties.

Afterwards, American submarines continued to track Soviet submarines, and Soviet submarines continued to use Crazy Ivan's tactics, which was the mission of both parties.

In reality, although there is a towed body sonar, it is very dangerous to carry such a thing at the tail when sailing at full speed. The towed body sonar is only used to detect targets in the cruise state.

The 949-class submarine, which is sailing at full speed, will turn around almost every hour to check its rear.

You must know that the noise at full speed makes it impossible for Class 949 to hide its whereabouts. Although it has the effect of the pycnocline, Neil Geyev is also a cautious person.

"Left full rudder," Nilgayev ordered.

"Understood, the left rudder is full." The helmsman operated the engine and turned it twice.

The rudder surface at the rear turned, and the submarine at a high speed of 30 knots, with a hull of 16,000 tons, came over like this, stirring up a lot of water currents and making new sounds.

The broadside sonar on the left was turned on long ago, and with the turn, the broadside aimed at the rear.

The sonar operator had been listening intently, and at this moment, he heard a familiar submarine.

"Los Angeles class! Distance one! Depth one hundred and five! Speed ​​thirty-three!" the sonarman shouted.

Damn Americans! Hearing this, Neil Gayev, who had always been calm, was stunned for a moment. Following that, he shouted, "Quick, the first water is drained, and it is urgent to float up!"

The underwater world is three-dimensional, in addition to fighting on the horizontal plane, you can also go up and down! Nilgayev's emergency ascent is not to surface, but to float up to a few dozen meters, and both parties can avoid it!

If both parties have a tacit understanding, they can float up and the other party dives, then they can avoid it in an instant!

However, Neil Geyev guessed wrong.

"Quick, the first head is drained, and the emergency floats up! The propeller is reversed, and the car is reversed at full speed!" After hearing the sonar operator's report, Collison was suddenly surprised when the other party came to a crazy Ivan at this juncture. Then, he gave his order to float up!

There is a reason why the captains all chose to go up urgently. After all, for submarines, they will face the threat of death at any time. No one wants to sink to the bottom. Going up is the first choice!

The seawater at the head was discharged, and the head suddenly became lighter. The huge hull began to tilt upwards. At the same time, the propeller at the tail began to reverse in the chorus of huge gear teeth.

If you want to reverse in the water, you have to rely on the propeller to reverse, but due to inertia, the submarine is still moving forward!

Hope to be able to stagger! Collison almost crossed his chest.

"Boom!" At this moment, a huge sound spread throughout the entire submarine.

If you can observe from the outside at this time, you can see that the two submarines that are preparing to go up at full speed are sailing up and down, and there is a close contact!

The hull of the 949-class nuclear submarine is huge and bloated, and its mass is almost twice that of Los Angeles, so its underwater maneuverability is not strong, but it first discovered the situation and emptied the first seawater, and it did not slow down, so , and the Los Angeles class behind it, evenly divided.

As for the Los Angeles class ~www.readwn.com~, if it didn't slow down just now, it would hit the first half of the 949 class directly. This deceleration still played a certain role, making its head match the front part of the 949 class. Passed by, but still did not get rid of the bad luck, the enclosure of the Los Angeles-level conning tower, hit the 949-level is below the rear!

If it collided at the front, both sides would have to sink. Although the 949-level double-hull submarine has good sink resistance, the non-pressure hull in front is equipped with P700 missiles! Under the impact of this kind of missile, once it is ignited, the consequence is almost an earth-shattering underwater explosion.

And now, Los Angeles hit the rear of the 949, and the enclosure of the conning tower collided with the belly of the rear of the 949. As a result, Oscar's huge hull moved two meters sideways! And this Los Angeles-class, after the conning tower hit the hull of the 949-class hull, it smashed a big hole in the non-pressure hull outside, and at the same time, it also got stuck on it!

The turbulent sea water poured in along the cracked control tower in Los Angeles.

"Damage control inspection!" On the 949-class nuclear submarine, Neil Gayev was also giving orders. The collision just now happened. What happened to the Americans is not up to him. He needs to protect his submarine. The collision just now happened. Incomparably violent, what happened to your own submarine? (To be continued.)
