As a professional anti-submarine ship, this warship is equipped with full-fuel power, two 22,500-horsepower M-8KF gas turbines composed of DT-59 accelerators and two 8,500-horsepower M-62 gas turbines as the core of the D-090 cruise thrust engine to drive the tail fixed-pitch propeller, the entire warship is following the formation, constantly accelerating.

The characteristics of gas turbines are that they start quickly and accelerate quickly, so that in anti-submarine warfare, it is easier to quickly occupy a place.

Gas turbines, in fact, are transformed from aviation power, and now, when they are started at full speed, the sound of turbines like airplanes is transmitted throughout the warship.

In this case, the noise of the warship itself will make its sonar almost inoperable, which means that the entire aircraft carrier formation will almost lose its anti-submarine capability. However, as a professional anti-submarine ship, the Project 1155 Dreadnought-class anti-submarine destroyer still has its own specialties.

In addition to the MG-342 "Opnoh/Orion" medium- and low-frequency search and attack hull sonar in the bow as the main means of detection, the Soviet has also made rapid progress in sonar over the years, and this warship also has one MG-335 "Плatnha/Platinum" variable-depth towed sonar. If from a technical point of view, it is not as advanced as the towed array sonar, but this towed sonar is now more than a thousand meters away from the hull, completely avoiding the noise of the hull, and this dreadnought-class is originally driving on one side of the formation, a few hundred meters away from other warships, so the range that can be observed is very large.

The sonar crew was on the quietest bridge of the whole ship, wearing headphones, listening carefully, they were always on guard against threats from underwater, and now, when the bubble-like sound came from the distance, the specially trained sonar officer immediately sounded the alarm: "A Los Angeles-class submarine, at a distance of fifty, a speed of twenty-five, and a bearing of 350, is approaching our formation!" ”

Underwater listening technology is constantly improving, when the Americans' Los Angeles-class submarines began to enter service, Soviet submarines are also tracking this latest American submarine, so the underwater sound characteristics of this submarine have long been entered into the Soviet sonar training database, and they have all been trained to listen to the Los Angeles-class sound.

"Left full rudder." Hearing the sonar alarm, while reporting to the fleet commander, the captain Petronov had already ordered his warship to intercept it!

Fifty nautical miles, in Peternov's opinion, the American submarine is already too close! Such a hostile act, the Soviet Navy will never turn a blind eye!

Now, it's time of war!

The hull of the warship, making a splash on the surface of the sea, the hull began to turn, and an arc with a radius of thousands of meters appeared on the sea, completing the turn, and at the same time, Petronov heard a report: "The blizzard is ready." ”

"Launch, four!" In the face of the approaching American submarines, as the escort of the Dreadnought-class, there is no room for relaxation at all, and it is the most violent blow when it comes up!

At this time, the course has been adjusted, the bow is pointing to the direction of the target, through the turn just now, the speed of the Dreadnought class has been reduced to 15 knots, after the gas turbine reduces the speed, the sonar of the bow provides the basic data binding for the launch of the blizzard, all of this, thanks to the increase of automated software, so that the speed of the battle is greatly accelerated!

Under the two sides of the bridge of the Dreadnought-class, the lid of the quadruple box-type anti-submarine missile launcher with an elevation angle of 16 degrees was opened, revealing the uniquely shaped equipment inside!

The Buran weapon system, which is a rocket-propelled torpedo system, is different from the form in which the United States places the propulsion device in the rear, the Soviet way is the hoisting type, that is, the design of the double projectile body, the upper part of the vehicle is a solid rocket, with a canard layout, foldable ****** and vertical tail, and there are large bundled booster rockets on both sides of the missile body, and the anti-submarine torpedo under the belly of the projectile body forms a double-body anti-submarine missile. This kind of system, codenamed SS-N-14 in the West, was originally thought to be anti-ship, after all, it was so big, and it was not until later that it was determined that it was a device that was mainly anti-submarine and supplemented by anti-ship.

Now, what is exposed is the bulging head, as the order to launch came, inside the blizzard device, a blazing flame came out, and the three engines of the booster rocket and the solid rocket ignited together, dragging the anti-submarine torpedo below, flying out of the launcher!

The wings opened, like a small cruising plane, this set of devices flew at an altitude of 100 meters above the sea surface, until it flew to a distance of 40 nautical miles, and then, the AT-2UM anti-submarine torpedo below, dragging a parachute, gently left the mounted missile and fell into the water.

Rocket-propelled torpedo, which is an anti-submarine weapon for surface ships developed by combining the advantages of all aspects! Torpedoes are underwater, relying on batteries or thermodynamic systems, range and speed are limited, although some torpedoes can have a maximum range of more than 40 kilometers, but this is done at a very low cruising speed, and when the torpedo arrives slowly, the target does not know where to run, and if the torpedo sails at the highest speed, the range will definitely not exceed 10 kilometers!

Therefore, with the help of the rocket propulsion system, let the torpedo fly through the air for most of the distance, wait until it is near the target, and then the torpedo falls down and burrows into the water to find the target, which is equivalent to installing wings on the torpedo, and the reaction speed is greatly increased.

It's just that in this way, you can't use the common line guidance method of torpedoes, all of them are self-guided torpedoes, and it is difficult to distinguish between friend and foe, and if you have your own submarine force underwater, it is easy to hit by mistake.

Fortunately, now Petrov knows that the submarine escorting his own side is within 80 nautical miles of the front of the formation, and it is not on his side at all, and the sonar crew has already heard the voice of the Los Angeles-class submarine, and it is completely certain that it is the enemy!

Look for death! Four torpedoes, I don't believe they can't kill you!

The launchers on both sides, with an interval of one second, each fired two anti-submarine missiles and four anti-submarine torpedoes, transferred into the water, and according to the pre-bound data, each launched its own search in four directions.

The moment the anti-submarine torpedo entered the water, there was a gentle splashing sound. And just 200 meters below the splash point, a huge submarine is facing a test.

"Four torpedoes." Inside the Los Angeles-class submarine, sonar crews reported to Captain Johnson: "We are being searched in four directions." (To be continued.) )
