"Go forward and release the shark tail." Colonel Yezhov ordered.Sharktail is the name of this towed array sonar.

In the dark sea water, a bubble suddenly appeared. Following the bubble, a towed sonar array was thrown out. Then, due to the resistance of the sea water, it left the submarine and landed on the rear of the submarine. Far.

Immediately, the sonar soldier felt that the sound from the headphones in his ears became clearer, and he carefully judged and compared.

The most important thing for sonar soldiers is their own ears. They have to conduct a lot of training every year to hear the tonnage and even the model of the other party's ships from the sound.

The loudest voice is estimated to have a tonnage of about [-] tons, and there are still faint voices around, which may be escort ships. Then, it is very likely that this is an aircraft carrier formation!

Chapter 875 Meeting on the "Narrow Road"

"Report, thirty degrees to starboard, distance one hundred, aircraft carrier formation noise." Finally, the sonar operator got confirmation.

The aircraft carrier formation is in the southeastern part of the Philippines at this time. In fact, if the sonar operator 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 an Oscar 2 nuclear submarine has encountered an aircraft carrier formation, just a hundred nautical miles away.

At this distance, the Granite anti-ship missiles carried by Oscar 2 can be launched long ago. Colonel Yezhov is very confident that the anti-ship missiles carried by their nuclear submarine can kill the opponent's missiles at a distance of [-] kilometers. Aircraft carrier formation.

The typical combat method of the 24 Granite SS-N-19 anti-ship missiles on the Oscar is that several missiles are launched at intervals. The missile follows covertly at low altitude, transmits the intercepted data to the low-altitude missile through the data link, and constantly corrects the flight trajectory by itself.During the flight, it will also receive medium-range guidance from helicopters or satellites.If the lead bomb is destroyed during the flight, a low-flying follower bomb will immediately rise and become the lead bomb until the attack is completed.

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

But now, he can't attack, so, as a brave Soviet naval submariner, approaching the opponent's aircraft carrier formation and obtaining more detailed information will play a big role in the process of fighting against the opponent's aircraft carrier in the future.

So, since the sonar found the target, Colonel Yezhov calmly made a choice to follow!Test the reaction of the opponent's anti-submarine forces, and at the same time test whether the quiet performance of your own submarine has reached what is stated in the technical manual.

"Retract the shark tail, right rudder three, two planes, advance three, after fifty nautical miles, two planes advance one."

First advance fifty nautical miles toward the opponent's position, and then slowly approach.

Following Yezhov's order, the nuclear reactor at the rear began to operate at 70.00% of its full load. With sufficient heat energy, a large amount of high-temperature and high-pressure steam was generated in the pipeline at the rear, driving the steam turbine at the rear, and then driving the two at the rear. The propeller is sailing quickly under 100 meters of water.

During the Cold War, the two sides often played this kind of game. Last year, a Soviet nuclear submarine bumped into an American aircraft carrier that was sailing in the process of surfacing, which made the Americans lose face. During the war, their aircraft carrier was killed long ago.

The K-132 Bielsanrod nuclear submarine is very lucky, because the US aircraft carrier formation is currently conducting air defense operations where carrier-based aircraft take off and intercept, and medium-range air defense missiles are ready to launch. The illusion is that they are approaching a certain When sailing along the coastline of a big country, it was raided by the opponent's shore-based air 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.

Carrier-based aircraft, if they want to take off from a deck that is more than 100 meters long, they face enormous difficulties. Land-based aircraft need a runway of more than 1000 meters, but aircraft carriers certainly cannot provide such a long distance.

The Soviet Union chose the method of jumping over the deck, making the bow of the ship upturned, increasing the angle of attack of the aircraft when it took off, and increasing the available lift, while the United States used steam catapults, high-temperature and high-pressure steam, to push the catapults. Piston drives the aircraft to accelerate forward to artificially increase the speed of the aircraft to meet the requirements for take-off.

但是，现在的航母上的弹shè器，xìng能依旧是不够强劲的，在后世，也只有美国最新开发出来的C-13-1和C-13-2型号的弹shè器有足够的功率能让飞机起飞。C-13-1型蒸汽弹shè器冲程达到94.6米,可将36.3吨重的舰载机以185节(即339千米/小时)的高速弹shè出去。

Therefore, if you want the plane to take off, only the catapult is not enough, you must try to accelerate it. This acceleration is to let the carrier of the plane, the aircraft carrier, accelerate itself.

When the aircraft carrier accelerates, it will give the carrier-based aircraft an initial speed. Although the carrier-based aircraft is not moving, there is already wind blowing. This is called deck wind.

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

What if the speed is not enough?That can only reduce the weight of the aircraft and reduce the mounts. In later generations, when Kuznetsov is equipped with a powerful fighter such as the Su-33, the advantages of this fighter cannot be brought into play when taking off from an aircraft carrier, because Therefore, even if the aircraft carrier flies against the wind at full speed, it is not enough for the fighter to take off with heavy loads. It can only reduce the weight, bombs and fuel load.

And even if the fighter jet is not taking off with a heavy load, in order for the plane to take off safely without accidents, it still has to sail at full speed.

Therefore, the current Kitty Hawk is running at full speed, resulting in a huge noise from the tail propeller. This huge noise was actually received by K-132 through the sea water.

Here comes the wolf.

Putting away the towed array sonar at the tail, K-132 rushed towards the direction of the Kitty Hawk aircraft carrier formation like a wolf seeing a lamb. In order to prevent being detected by the opponent, K-132 did not advance at full speed.

The vibration of the entire power unit is fully absorbed by the shock-absorbing base, and the sound introduced into the sea water is weakened again through the sound-absorbing tiles laid on the side. The seven-bladed large skewed propeller is deliberately concealed while providing power look at yourself.

After driving for nearly fifty nautical miles, K-132 slowed down again. If the azimuth detection just now was accurate, they might have already approached fifty nautical miles away from the opponent's formation. The Los Angeles-class attack submarine found below.

Moreover, the K-132 needs to be slow so that its passive sonar can play a better role and determine the exact position of the opponent. Maybe it needs to use a towed array sonar.

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

In this aircraft carrier formation, there is only one nuclear submarine No. 689. This Los Angeles-class submarine is a relatively new submarine that served in 81.The construction of the Los Angeles-class nuclear submarine started in 72, and the first ship entered service in 76. It has become the main attack nuclear submarine of the US Navy.

The displacement of such nuclear submarines is "only" seven thousand tons.Compared with the [-]-ton nuclear submarine of the Soviet Union, it is indeed too small, less than half of the Oscar class, but compared with conventional submarines, and even compared with the United States' own nuclear submarines, it can be regarded as the mainstay.

However, although compared with surface ships, as black holes in the ocean, submarines attach great importance to their noise reduction performance, but at this time the Los Angeles class did not install sound-absorbing tiles, until the SSN88 "San Juan" in service in 751 It was not until now that the No. [-] began to install sound-absorbing tiles, and replaced the shell rudder with the bow level rudder, which can be freely stretched and retracted when floating in the ice area.

However, although no sound-absorbing tiles are installed, the noise of the Los Angeles class is only about 110 decibels. This is due to the S6G natural circulation pressurized water reactor. The energy generated by fission becomes heat energy, heats the coolant, releases it at the same time, heats the water in the secondary circuit, and then sends the coolant back. This sending back requires the circulating water pump of the primary circuit. This circulating water pump , can be said to be the biggest source of noise for nuclear submarines besides the propeller.

And this kind of natural circulation pressurized water reactor cancels the water pump of the primary circuit, which greatly reduces the source of noise.

In the later generations, the more abnormal one is the high-temperature gas-cooled reactor. This reactor relies on nitrogen as the cooling medium of the primary circuit, and has various excellent performances. (It is said that our country is in the advanced position in the world with this technology.) At this time, the Baton Rouge was searching the surrounding waters in front of the aircraft carrier. The front of the -132's side sonar detection.

As the shark's ribs were detected again, when K-132's body slowly changed its orientation, the sonar soldiers finally gained something.

"Report, [-] degrees to port, [-] nautical miles away, there is an American aircraft carrier formation."

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 soldiers continued to report: "Initial judgment, it is a Kitty Hawk-class conventionally powered aircraft carrier. Destroyer, the feature is not very obvious, need to continue to approach to be able to distinguish, did not find the opponent's submarine."

Suddenly, the sonar soldier said with some surprise: "They are now turning around and coming towards our side."

At 60 nautical miles, the underwater acoustic characteristics of the opponent's warship are not very obvious. It needs to be within [-] nautical miles to be able to use the sonar's resolution ability. However, the opponent is now advancing at full speed, and this [-]s ship is in service. The aircraft carrier was monitored by the Soviet Navy many times, and the first-hand sound data was intercepted. It was probably the sound that the sonar soldiers heard the most during training, so it was finally identified by the sonar soldiers.

Chapter 876 Is there a Soviet submarine underwater? !

Although in theory, steam catapults have unparalleled advantages, helping carrier-based aircraft overcome their own power limitations and take off from small aircraft carriers with full load, but steam catapults also have disadvantages.

Among them, the biggest disadvantage is that it will consume a lot of steam. You must know that the aircraft carrier needs to sail at full speed, and the steam boiler needs to provide a large amount of steam to power the steam turbine. However, the steam bomber will also compete with the aircraft carrier for precious steam.

Therefore, after firing two squadrons of F-14 fighters, the pressure of the steam dropped, and the speed of the aircraft carrier dropped to 27 knots. At this time, the Kitty Hawk suspended the take-off of the fully loaded F-14 fighters, The next take-off will take place only when enough power is stored.

Two more squadrons of F-14 fighters took off. At this time, there are already sixteen F-14s in the sky, enough to carry out enough air defense operations under the command of the E-2 pre-warning aircraft. A Kitty Hawk-class aircraft carrier , 20 F-14s are equipped as standard, except for one squadron that is maintained in the hangar below, the rest have been used.

After taking off the air defense fighter, the aircraft carrier no longer needs to sail against the wind, and naturally has to turn according to the original course. This turn is exactly on the K-132's route.

"Slow down to 3 knots and slowly dive to 150 meters." Yezhov ordered.

This time, our side was lucky, and finally caught a big fish. As Soviet submariners, this was the most exciting moment for them, and let the Yankees know how good they are!An entire fleet of aircraft carriers, an invincible fleet built with more than 100 billion US dollars, is simply not as good as a submarine of the Red Navy.

Although no opponent's submarine has been found so far, there is no doubt that the US aircraft carrier formation will be equipped with one or two attack nuclear submarines to escort. Ye Ruofu is very confident that the performance of his own nuclear submarine is better than that of the opponent. However, he also knows that the quietness of American submarines is very good. If the own side has a new type of propeller, the noise may be even louder than that of the other side.The opponent's submarine has not been found now, it may be because it is far away, or it may be in another direction.

Although the other party's submarine was not found, and Ye Ruofu was convinced that the other party must have a nuclear submarine, he did not order to use a towed array sonar with a longer detection range and higher precision. Now, as the distance between the two sides increases The closer he gets, the more he has to do things like speed up and leave after being discovered by the opponent. If he releases the towed array sonar, it may be too late to take it back, so he can only cut it off. It is understandable in wartime, but now , Lost the precious tail, the commander of the base will reprimand him to tears after returning.

After determining the other party's position, according to the estimated preset point, K-132 is slowly moving forward. When it sails at a speed of 3 knots, it will almost completely hide its voice in the background of sea water.

The Kitty Hawk aircraft carrier formation is now mainly conducting air defense exercises. Therefore, apart from turning on the passive sonar at the bow of the outermost Perry-class frigate, it hardly pays much attention to the underwater.

Underwater is safe because of the Los Angeles submarine!
