w "Report, starboard thirty degrees, distance of one hundred, aircraft carrier formation noise." Finally, the sonar was confirmed.

The aircraft carrier formation, the sea area at this time, is in the southeast of the Philippines. In fact, if the sonar confirms that it is the noise of the aircraft carrier formation, there is no other possibility. It must be the US aircraft carrier formation!

This is the first time that the Oscar Class 2 nuclear submarine encountered an aircraft carrier formation, just one hundred nautical miles away.

At this distance, the granite anti-ship missiles carried by Oscar 2 have long been launched. Colonel Ye Ruofu is very sure that the anti-ship missiles carried by their nuclear submarines can kill the opponent's aircraft carrier formations at 500 kilometers away.

The typical combat method of the 24 granite ss-n-19 anti-ship missiles on the Oscars is to launch several intervals. After all, a leading missile flies at high altitude to better capture the target. The remaining missiles follow secretly at low altitudes, and pass the intercepted data to the low-altitude missiles, constantly correcting the flight orbit by themselves. During the flight, helicopters or satellites will also be subject to medium-range guidance. If the leading missile is destroyed during the flight, a low-altitude follow-up missile will immediately rise and become a leading missile until the attack is completed.

So, if he wants to attack the opponent's aircraft carrier now, there is no possibility of escape.

But now, he cannot attack, so as a brave Soviet naval submarine soldier, approaching the opponent's aircraft carrier formation and obtaining more detailed information will play a great role in the future when fighting against the opponent's aircraft carrier.

So, since sonar discovered the target, Colonel Ye Ruofu made a choice calmly and followed the past! Test the reaction of the opponent's anti-submarine force. At the same time, test whether the silent performance of his submarine was as stated in the technical manual.

"Calling the shark's tail, right steer three, dual-machine, three, fifty nautical miles later. Two-machine advance one."

First move towards the other party’s location, go fifty nautical miles, and then slowly get closer.

With Ye Ruofu's order, the nuclear reactor at the rear began to operate at 70% of the full load, with sufficient heat energy, allowing a large amount of high-temperature and high-pressure steam to be generated in the pipeline behind, pushing the steam turbine behind, and then driving the two propellers at the rear to sail quickly under a water of 100 meters.

During the Cold War, both sides often played this game. Last year, a Soviet nuclear submarine actually hit a U.S. aircraft carrier in a state of navigation while floating, causing the Americans to lose face. If it were in the war, their aircraft carrier would have been killed long ago.

The K-132 Belsanrod nuclear submarine is very lucky because the US aircraft carrier formation is currently carrying out carrier-based aircraft take-off and intercepting. The air defense operations prepared for medium-range air defense missiles are expected to be launched. The illusion is that when sailing near the coastline of a major country, it was raided by the opponent's shore-based aviation force.

Therefore, in order to take off the carrier-based aircraft, the Kitty Hawk aircraft carrier is now sailing against the wind at full speed.

The difficulties faced by carrier-based aircraft to take off from a deck that is more than 100 meters long are huge. Land-based aircraft require a runway of more than 1,000 meters, but aircraft carriers certainly cannot provide such a long distance.

The Soviet Union chose to jump the deck to raise the bow, increase the angle of attack during takeoff, and increase the available lift. The United States used steam catapults, high-temperature and high-pressure steam, which pushed the catapult's pistons, drove the aircraft forward, artificially increased the aircraft's speed and met the requirements of takeoff.

However, the performance of catapults on current aircraft carriers is still not strong enough. In later generations, only the latest c-13-1 and c-13-2 catapults developed by the United States have enough power to take off the aircraft. The c-13-1 steam catapult stroke reaches 946 meters, and can eject a 363-ton carrier-based aircraft at a high speed of 185 knots, that is, 339 kilometers per hour.

Therefore, if you want the aircraft to take off, it is not enough to have a catapult. You must find another way to accelerate. This acceleration means to accelerate the aircraft's carrier and the aircraft carrier themselves.

When the aircraft carrier accelerates, it will give the carrier-based aircraft an initial speed. Although the carrier-based aircraft does not move, wind is already blowing, and this is called deck wind.

For example, the F-14a fighter will reach a total weight of 31 tons under heavy load (all hateful birds, each weighing half a ton, and under full state, it can carry six). In this case, the aircraft carrier needs to sail at full speed to 33 knots before it can be safely ejected.

What if the speed is not enough? It can only reduce the weight of the aircraft and reduce the loading. In later generations, when Kuznetsov equipped a powerful fighter such as the Su-33 and took off from the aircraft carrier, the advantages of this fighter could not be exerted, because even if the aircraft carrier flew at full speed against the wind, it was not enough to allow the fighter to take off with heavy load. It can only reduce the weight and reduce the amount of bullets and fuel loading.

Even if fighter jets do not take off heavily, in order to allow the aircraft to take off safely and avoid accidents, they still have to sail at full speed.

Therefore, the Kitty Hawk is running with all its might, causing huge noise from the tail propeller. This huge noise was actually received by k-132 through the sea water.

The wolf is here.

Putting away the towed array sonar at the tail, the k-132 seemed to have seen a sheep and rushed towards the direction of the Kitty Hawk aircraft carrier formation. In order to prevent the opponent from detecting it, the k-132 did not advance at full speed.

The vibration of the entire power unit is fully absorbed by the shock-absorbing base, and then the sound transmitted into the sea water through the sound-silenced tiles laid on the side becomes weaker again. The large side oblique propeller of the seven-leaf is providing power, and is also deliberately concealing itself.

After driving nearly fifty nautical miles, the k-132 slowed down again. If the position detection was accurate just now, they might have approached fifty nautical miles of the other party's formation. At this distance, they would be discovered by the Los Angeles-class attack nuclear submarine below the aircraft carrier formation at any time.

Moreover, the k-132 needs to be slow, so that its passive sonar can work better and determine the exact direction of the other party. Perhaps, it also needs to use drag array sonar.

Fifteen nautical miles in front of the Kitty Hawk, a Los Angeles-class nuclear submarine, SSN689 Baton Rouge, is faithfully carrying out its mission to check for possible potential threats in the front of the aircraft carrier.

This time, the aircraft carrier formation has only one nuclear submarine No. 689. This Los Angeles-class submarine is a newer submarine that was put into service in 1981. The Los Angeles-class nuclear submarine started construction in 1972 and was first put into service in 1976. It has become a major attack nuclear submarine of the US Navy.

The displacement of this nuclear submarine is "only" 7,000 tons. Compared with the Soviet 10,000-ton nuclear submarine, it is indeed too small, less than half that of the Oscar class. However, compared with conventional submarines, and even with the United States' own nuclear submarines, it is also a mainstay.

However, although compared with surface ships, as black holes in the ocean, submarines attach great importance to their noise reduction performance, the Los Angeles-class did not install silencer tiles at this time. It was not until the ssn751 "San Juan" that was in service in 1988 that it began to install silencer tiles, and replaced the enclosure rudder with its first horizontal rudder, which can be retracted freely when floating on the ice area.

However, although there is no silence tiles installed, the noise of the Los Angeles-class is only about 110 decibels. This is due to the s6g natural circulating pressurized water reactor. As the main power of the nuclear submarine, the nuclear reactor undertakes the task of heating the boiler. The energy generated by the nuclear fission of the nuclear reactor becomes thermal energy. Heat the coolant and release it at the same time, heating the water in the second circuit, and then sending the coolant back. This return requires a circulating water pump of the first circuit. This circulating water pump can be said to be the largest source of noise for the nuclear submarine besides the propeller.

This natural circulating pressurized water reactor eliminates the one-circuit water pump, which greatly reduces the source of noise.

In later generations, the more abnormal one was the high-temperature gas-cooled reactor. This reactor relied on nitrogen as a first-circuit cooling medium and had various excellent performances. (It is said that this technology is in the world's advanced position.)

At this time, the Baton Rouge was searching for the surrounding waters in front of the aircraft carrier. When the formation turned, it followed suit. As a result, it was blocked by the noise of the aircraft carrier on the side sonar detection front of the k-132.

With the detection of the shark ribs again, when the k-132's body slowly changed its position, the sonar soldiers finally gained something.

"Reported, there is a US aircraft carrier formation at fifteen degrees on the port side, forty nautical miles."

This time, the sonar soldiers were completely convinced that it was the American aircraft carrier formation!

After listening carefully for a few minutes, the sonar continued to report: "A preliminary judgment is that it is a conventional Kitty Hawk-class aircraft carrier, which is now sailing at the highest speed. It is likely to be a take-off and landing fighter jet, with two cruisers and two destroyers on the side. The characteristics are not very obvious and you need to continue to get close to it to distinguish. No opponent's submarine was found."

Suddenly, the sonar soldiers said in some surprise: "They are turning now, coming to our side."

At forty nautical miles, the water sound characteristics of the opponent's warship are not very obvious. They need to be within twenty nautical miles to be able to better utilize the sonar's discernment ability. However, the other party is now moving forward at full speed, and this aircraft carrier, which was in service in the 1960s, has been intercepted by the Soviet Navy many times, and has intercepted the sound information. The most heard in the sonar soldiers' training is probably its sound, so it was finally identified by the sonar soldiers. To be continued.
