Pacific Ocean, ten nautical miles east of Vladivostok.

A dark-sized behemoth, like a ghost, had its head cleared away the rolling sea water, like a big shark.

On the bridge in the middle, a flag with a sickle and axe was still flying. The k132 on the side was almost invisible in the dark night.

The captain, who was already forty years old, Navy Colonel Yeruofu was breathing with satisfaction the smell of the cold sea breeze. They were about to dive.

"Young men, please be careful, after two minutes, you will be ready to dive." Colonel Yeruofu said.

Hearing this order, the young Soviet submarine soldiers began to prepare.

Before performing this mission, Ye Ruofu once asked a soldier: "We are about to conduct a combat readiness cruise. It is possible that we will not be able to float under the water for more than a month. Will you feel uncomfortable?"

"No, because, besides working, I can go to the gym to exercise and also go to the swimming room to swim. Our submarine is not even a problem if it doesn't float for three months!"

They are proud because the submarine under their feet is the largest nuclear submarine in the Soviet Union, apart from the Typhoon class, the 949a class nuclear submarine. The number given by NATO is called the Oscar Class 2 nuclear submarine.

This nuclear submarine is a unique submarine of the Soviet Union. In Western countries, there are only two types of attack nuclear submarines and missile nuclear submarines. Missile nuclear submarines carry long-range ballistic missiles and undertake secondary counterattack tasks after being attacked by nuclear. In order to protect missile nuclear submarines from wandering in the waters far away from their own side, attack nuclear submarines need to be used to undertake underwater protection tasks to prevent enemy submarines from attacking.

The Soviet Union did not have strong aircraft carrier power and used missiles as its main weapon to attack the opponent's warships, especially the opponent's aircraft carrier formation. The Soviet Union developed a multi-type supersonic anti-ship missile, using saturation attack methods to attack the opponent's aircraft carriers.

In addition to warships and aircraft, there is another type of carrier, which is nuclear submarine!

Using nuclear submarines has many advantages. The biggest advantage is that the nuclear submarine is sailing underwater and is relatively hidden, and will not disclose its whereabouts. It sails to the periphery of the opponent's fire circle. For example, at a distance of 500 kilometers, it can launch all the anti-ship missiles it carries. After launching, it can also escape with the cover of seawater. It is very sudden and sudden.

Therefore, among the submarines equipped by the Soviet Union, there is a special cruise missile attack nuclear submarine. The latest model of this nuclear submarine development is also the fourth-generation cruise missile attack nuclear submarine of the Soviet Union. It is the 949a-class nuclear submarine under Ye Ruofu's feet. This is the second nuclear submarine of this class, and the first one is arranged in the Northern Fleet.

This nuclear submarine is 150 meters long and has an underwater displacement of up to 18,000 tons. It adopts a typical double-shell structure. It is all made of titanium alloy and is expensive. There are 24 p700 granite anti-ship missiles arranged between the inner and outer shells at a distance of four meters wide, and the NATO code name... The double-shell is a commonly used design for Soviet submarines. Western submarines have a layer of steel plate outside and various equipment are installed inside. In this way, there will be a disadvantage. When the shell hits something and causes the shell to be damaged, the entire submarine will face the risk of sinking.

For Western countries, this is understandable, but for the Soviet Union, it is different, because most of the Soviet submarines are active in high-latitude areas. When they float, it is possible that there is no sea water at all, but thick ice layer. They need to break out of the ice with their own shells.

Therefore, the Soviet submarines were covered with a layer of shells outside the single shell. The outside was non-pressure-resistant shells, filled with various equipment that did not require personnel operation. The outside was holes, and after diving, between the inner and outer shells, besides the equipment, there was sea water. Another advantage of this is that they had strong anti-strike ability.

When hit by a torpedo, it will cause damage to the non-pressure-resistant shell on the outside. However, if the torpedo is not powerful enough, it will not damage the internal pressure-resistant shell. The submarine can also carry out various normal activities, especially the Oscar Class 2 nuclear submarine, the distance between the two layers reaches four meters. This means that the existing anti-submarine torpedoes in the United States are tickling for it.

However, as long as one granite carried by Oscar Level 2 is hit, even if it is an aircraft carrier, it will definitely not be able to withstand it. Moreover, 24 missiles, even if they are launched in two batches, will successfully break through the air defense circle of the US aircraft carrier and successfully kill the opponent.

To strike against the US aircraft carrier, this is the Oscar's mission!

In addition to anti-ship missiles, Oscar Level 2 also has various advanced torpedoes, which can be handled for a while even if it encounters the Los Angeles-class attack nuclear submarine from the United States.

If the disadvantage of the double-hull is that it will increase the size and increase the displacement. The main Los Angeles-class nuclear submarine in the United States has an underwater displacement of only 7,000 tons, less than half of the Oscar Level 2.

Large displacement requires larger nuclear reactors, larger turbines and generators, and larger propellers. What follows is huge noise.

Nuclear submarines can become hidden killers underwater because they will not be seen by others, but the noise will expose its identity.

Therefore, this is also a major aspect of the Oscar-level improvement to the Oscar-level 2. All vibration equipment is installed on the shock absorber base and sound silencer tiles are laid outside the hull. The main source of noise is the propeller.

Among all the noise sources of submarines, the noise of the propeller is the greatest. When the propeller stirs the sea water and provides power, it also causes a lot of noise. However, if a special-shaped propeller is used, the flow of sea water and the rotation of the propeller can be fully combined to minimize noise. This kind of propeller of special-shaped is very troublesome to process and requires very high accuracy. These can only be achieved by multi-axis linkage large CNC machine tools.

Now, the great Soviet Union can finally process such large seven-blade large side-swing propellers. Compared with the original propellers, the noise is one order of magnitude lower, and it is even comparable to the Los Angeles level.

Last year, the Soviet Union began to replace these propellers on newly built warships to increase power and reduce noise.

After the submarine is equipped with the troops, it will join the combat readiness duty and arrange its cruise mission. Now, it is finally K132's turn.

With the captain's order, all the personnel began to prepare. The personnel on the bridge began to enter the submarine. The last crewman who went down closed the hatch.

The entire submarine becomes a world insulated from the outside world.

"Fill in the ballast water tank."

This huge submarine requires more than 100 officers and sailors to operate. Although it is because of the huge ship, it is also related to the lack of more automation in the backward operating system.

As the valve was opened, sea water poured into the main ballast water tanks in front and behind. The huge hull, like a ghost, slowly sank into the dark water.

"Balance the hull and check the sealing conditions of each part."

As a submarine soldier, the dangers they are in great importance, and even a small problem may lead to catastrophic consequences.

Therefore, strict operation is necessary. After the dive is completed, the situation of each part needs to be checked, especially for this submarine that is conducting a long-distance voyage for the first time.

After receiving normal reports from all parts, Colonel Ye Ruofu issued a second order: "Two chariots, go forward three."

With his order, the two seven-blade large side-spin propellers weighing several tons at the tail began to stir the sea water at a faster speed, and the entire underwater monster began to accelerate.

Due to design reasons, the resistance of the submarine underwater is less than that of the water, and the propeller underwater is more efficient, so the underwater speed is higher than that of the water.

"The horizontal rudder leans forward thirty degrees and dives to thirty meters deep." Ye Ruofu was calm and calm when he directed the Oscar submarine. He hoped to gain something during their voyage.

Western Pacific.

The sun shines on the sea in northeastern Philippines. A routine training group is being conducted centered on a large aircraft carrier and is centered on several destroyers and cruisers around.

This aircraft carrier is the Kitty Hawk.

Since the Kitty Hawk was launched in the 1960s, this has been considered a battle-tested aircraft carrier, almost fighting on the front lines of the Western Pacific, the Vietnam War, the Iranian hostage incident... The ninth carrier-based aircraft wing on the aircraft carrier has already had 180,000 hours of flight and more than 7,000 aircraft carrier takeoffs and landings.

The aircraft carrier is the most proud maritime force of the United States.

The temperature on the deck is very high. An F14 fighter was already on the takeoff line. The ejection hook in front of the fighter's nose wheel has been lowered and is being connected to the catapult. The tension rod at the rear has been connected to the nose wheel. The deflector at the tail has been folded. The ejection in the yellow uniform is long and is ready.

All kinds of preparations are completed, eject the long lunge step, put your right hand behind you, and finger your left hand forward.

Suddenly, the flames spit out by the engine at the tail of the f14 turned into bright colors. The steam catapult cylinder at the lower part, nearly one ton of fresh water steam, pushed the piston, generating four g accelerations.

Suddenly, the pilot felt his body beneath the flight seat, and the muscles on his face were pulled up. With a huge feeling of pushing back, the f14 fighter left the deck.

The aircraft carrier itself does not have any attack capabilities. The strength of the aircraft carrier lies in the carrier-based aircraft it carries.

Under the sea, two Los Angeles-class attack nuclear submarines searched about fifty nautical miles in front of the formation. They were responsible for underwater protection to prevent encountering enemy nuclear submarines.
