Red Soviet Union

If you want to be a submarine soldier, you must endure loneliness. In submarine combat, whoever is the most patient will be able to survive until the end!

One minute, two minutes...an hour passed, and finally, the anti-submarine depth bomb was not dropped again.

One hour, two hours... six hours passed! Finally, the voice of the opponent's aircraft carrier formation gradually decreased, and they had already gone away!

Turn on the reactor, speed at 15 knots, prepare to follow! Captain David said.

As a Jewish nation, we will never give up!

The reactor at the tail gradually increased its power from the almost shutdown state just now, the propeller at the tail turned, and the submarine refloated, ready to accelerate!

The surrounding area seems to be very calm. The large seven-blade tilting propeller at the tail of the submarine is constantly rotating, pushing the submarine and accelerating it to a cruising speed of 15 knots. In this case, the noise of the submarine will also increase to about 115 decibels. However, The noise is still very low, if you are not close, you will never find it!

Plop! At this moment, a voice came from the sea again!

Hearing this voice, the sonar operator's face suddenly changed, Oops, it's been tricked!

The Soviets are more calm than their own! Moreover, the buoys they dropped were not only active sonar buoys, but also passive sonar buoys!

When the opponent started to cast, they used active sonar buoys to quickly discover the existence of their own side, but when their own side sank, the opponent used passive sonar buoys instead!

It is completely opposite to the operation of the US Navy. It simply does not follow the routine. It is simply too hateful! And their method successfully tricked the Los Angeles class!

The endurance time of the Ka-27 helicopter is not so long. At this time, there are already four other Ka-27 helicopters waiting above the sea! The sonar guys have been quietly listening, and they're hovering overhead! Because they know that the submarine must still be hiding below!

Now, after hearing the underwater sound, the sonar operator immediately called another Ka-27 helicopter, this time, directly dropped an anti-submarine torpedo!

Torpedo attack!

After the torpedo fell into the water, immediately follow the direction determined by the sonar buoy and rush towards the target! At this time, the distance between the two sides was only five kilometers!

The propeller at the tail of the torpedo rotates at high speed, and it has locked on to the target nuclear submarine!

Release the air bubbles, reduce the speed to 3 knots, and turn the rudder to starboard! Captain David ordered.

The torpedo has come down! There is only one way for our side, to escape!

dodge!

The bubbles will form an air wall on one's side, blocking the transmission of sound, and completely shielding the opponent's torpedo seeker! After all, whether it is active or passive, sound is needed to transmit!

At the same time, the sudden change of direction of the submarine can also make the opponent lose the source of the target, and continue to attack in the direction just now, and the purpose of evasion can be achieved!

The hull of the boat began to tilt, and after completing the movement of the full starboard rudder, they left the sea area just now, and a large piece of air bubbles filled the sea area just now.

Successfully evaded. The sonar crew's back was soaked, and the air bubbles also isolated their own sonar, until the torpedo could not find the target after passing through the air bubbles, and then blew itself up at the end of the voyage. OK, the dodge is complete!

David breathed a sigh of relief, he knew that this was just the beginning!

Because, as long as he is discovered, it means that there will be a large number of attacks on the sea and in the sky!

Sure enough, almost at the same time that the first torpedo blew itself up, the sonar operator heard the sound of the torpedo falling into the water again.

God, what kind of weapon are they using? The sonar operator was shocked, because the second torpedo was fired at an extremely fast speed! Now, the opponent has exceeded the high speed of 50 knots and is still accelerating!

Supercavitating torpedoes! The Soviet's sharp weapon against underwater targets!

The pursuit of speed will never change, and the resistance of sea water will cause the speed of various water surfaces and underwater equipment to slow down.

A surface ship can have a speed of 30 knots, which is already quite high, but underwater, it is almost impossible for a torpedo to break through the limit of 50 knots.

Therefore, if you want to be faster, you have to think about other means. The supercavitation torpedo was invented under this situation.

The density of seawater is about 900 times that of air, and the resistance of seawater is also 900 times greater than that of air. If you let the torpedo sail in the air, it will be much faster than in seawater! However, torpedoes sail in sea water again! This requires special means!

That is to use certain technical means to create bubbles on the outside of the torpedo to wrap the entire flying object to form a gas coat, so that the object can always sail inside the supercavitation created by itself, thereby avoiding the viscous resistance of water to the greatest extent. , to achieve high-speed navigation.

The Soviet Union has achieved this kind of breakthrough and produced this high-speed torpedo with a speed of 200 knots!

This torpedo does not use a propeller, but a rocket thrust engine!

And another defect is that this kind of air bubbles will block the transmission of sonar signals. Therefore, this torpedo cannot be a self-guided torpedo. Device signaling!

The air curtain launched by the submarine can make the torpedo stray, but it cannot deceive other equipment! For example, now, this heavy torpedo dropped by the Ka-27 helicopter, after entering the water, is guided by the target information transmitted by the sonar buoy array! First it sent back the helicopter that dropped the sonar, then the helicopter that dropped the torpedo, and then the torpedo!

Under the water, the speed of the torpedo was astonishing, and the rocket engine at the tail ejected a hot wake. Finally, it accelerated to 200 knots!

On the Los Angeles-class submarine, there was nothing but ashes, and only Lieutenant Colonel David was still sane. He shouted loudly: Empty all the water tanks!

The maneuverability of submarines underwater is quite poor, especially now, with a speed of 3 knots, the effects of various rudder surfaces are even negligible! If you want to avoid this torpedo, you can only empty the sea water in the ballast tank, and the submarine will float up at full speed! Only in this way can we avoid each other!

If hit by this kind of thing, even if the opponent's warhead didn't explode, just relying on this speed would be enough to knock one's own hull into two pieces!

Terrible, terrible!

But, it's still too late! After receiving the order, the submariner in charge of the operation quickly turned on the switch and used high-pressure air to empty the sea water. The hull of the boat was shaking and began to rise. At this time, the torpedo that came at a high speed of 200 knots had already Hit hard!
