Chapter 181 A Single Nuclear Submarine Intercepts the Fuso Anti-Submarine Fleet
Since submarine underwater communication is a problem that cannot be solved at present or even in the modern time and space of the original world, in this battle against the Fuso anti-submarine formation, each submarine fought on its own and was unable to cooperate with each other.
The first to arrive at the coordinate sea area was a Hurricane-class attack nuclear submarine from the Third Nuclear Submarine Squadron, hull number UH-1108.
In the naming rules of the Restoration Army Navy, U stands for submarine and H stands for nuclear submarine.
The first 1 represents the First Fleet, the second 1 represents the First Submarine Squadron, each squadron has three nuclear submarines, and the 08 means it is the No. 2 boat of the Third Squadron.
The UH-1108 submarine is the closest one to here.
When it arrives at the target sea area, it raises the periscope and searches for the target in the sea.
"Report to the captain, there is an approaching aircraft, bearing 08, distance!"
Upon hearing this, Qi Hong, the captain of the UH-1108 submarine, retracted the periscope as quickly as possible.
Also retracted was the retractable warning radar carried by the Hurricane-class attack nuclear submarine.
Whether a submarine can detect targets at a long distance depends on this warning radar.
"It seems that the Fuso fleet is nearby!"
The only aircraft that appeared here were seaplanes carried by the Fuso cruiser.
The operating distance of seaplanes is generally very short, only about 100 kilometers.
So they were very close to the Fuso anti-submarine formation.
More than ten minutes later, the periscope and warning radar of the UH-1108 submarine were upgraded again.
"The plane has left the airspace, the airspace is safe!"
Qi Hong scanned the surrounding sea area again through the periscope, but still found nothing.
"Release the communication buoy, contact the early warning aircraft, and let them guide us."
A few minutes later, a brief telegram came from an EC-121 airborne early warning aircraft.
There was only one coordinate in the telegram, and they could wait at this coordinate for the Fuso anti-submarine fleet to come to them.
Looking at the coordinates in his hand, Qi Hong hurried to the chart room and began to manually map the coordinates on the telegram.
After determining the specific location, the UH-1108 attack nuclear submarine began to move forward at full speed.
Half an hour later, the submarine reached a maximum speed of 25 knots.
At this speed, the submarine cannot last for long.
Half an hour later, the speed dropped directly to 23 knots.
This speed is much faster than the 18-knot economic speed of the Fuso anti-submarine formation.
When the UH-1108 submarine arrived, the Fuso anti-submarine fleet was still on the way.
All they had to do now was wait.
Moreover, the early warning aircraft sent them relevant information about the Fuso anti-submarine formation almost every hour.
It was not until three hours later that the early warning aircraft sent its last message.
At this time, without the need for early warning aircraft, Qi Hong also discovered the Fuso anti-submarine formation heading towards them through the periscope more than 20 nautical miles away.
Qi Hong took a look at the location of the Fuso fleet, then he understood something and immediately put away the periscope.
"Right 60 degrees, forward 1, continue straight for 1.2 nautical miles."
The nuclear submarine that had been dormant in this sea area for a long time finally began to move and began to move slowly.
At this speed, the submarine can remain silent.
The new sonar technology currently used on Fuso destroyers and cruisers is derived from the ASDIC sonar that was put into service by John in 31. This sonar is also the most advanced sonar technology currently available.
But when these technologies came to Fuso, some changes occurred.
Because the Japanese had weak industrial capabilities, the sonars they produced using this technology were not only unreliable, but also had data such as detection distance and noise detection that did not meet the standards.
It will probably take several years for them to fully absorb the technology of ASDIC sonar and produce sonar of the same level.
What we are equipped with now are just emergency products.
Not to mention this kind of emergency product, even if the ASDIC sonar is directly equipped on their ships, it cannot detect the Hurricane-class attack nuclear submarine in silent navigation.
Because the noise of the Hurricane-class attack nuclear submarine sailing in this state is basically controlled at around 135 decibels.
In terms of noise control, the Hurricane-class attack nuclear submarine has reached the technical level of the second-generation nuclear submarine.
Although 135 decibels is not absolutely silent in the ocean, at a certain distance, the Japanese sonar cannot detect the Hurricane-class attack nuclear submarine.
The UH-1108 submarine moved forward at a silent speed of 5 knots and began to occupy the attack position.
An hour later, the distance between the two sides was close to about 2 nautical miles.
The Fuso anti-submarine formation sailed straight forward, and the speed of each ship basically remained at around 18 knots.
At this speed, the ASDIC sonar cannot work properly.
Because once the speed exceeds 18 knots, the noise level of the ship will rise sharply, which will affect the operation of the sonar.
"Torpedo No. 1 and No. 2 are launching, with an interval of 2 seconds."
As the order was issued, the UH-1108 attack nuclear submarine fired two MK35 mod3 sonic homing torpedoes in succession.
Sailing ahead of the torpedo was the Mizunoe destroyer, one of the Mutsuki-class destroyers.
This is a torpedo destroyer that has been in service for 27 years and has a tonnage of only 1770 tons.
Two anti-aircraft guns on both sides of the destroyer were removed and depth charge throwers were installed to make it a supplementary ship for anti-submarine warfare.
From this we can also see that the current Fuso Navy attaches great importance to air defense and anti-submarine.
After all, they suffered such a huge loss, it is impossible for them to fall into the same pit twice.
Launched at a safe distance of 2 nautical miles, the destroyer Mizunoe was hit without being aware of it.
Two MK35 torpedoes were traveling at a top speed of 27 knots. Once they locked onto the destroyer Mizunoe, it had no chance of escape.
MK35 torpedoes hit the destroyer Mizunoe one after another.
The torpedo was like a sharp arrow in the water, directly penetrating its thin underwater armor and diving into the bottom of the ship.
“Boom…Boom…”
The two explosions sounded almost simultaneously.
The more than 1700-ton Mizunoe destroyer was lifted out of the water in the violent explosion and broke into two pieces in the air.
Then it fell heavily onto the sea.
At this time, the violent explosion also set off a water column tens of meters high.
This sudden change stunned all the Fuso sailors and officers who saw this scene.
The ship closest to the explosion was the Myoko heavy cruiser rushing in front.
If the Mizunoe had not been about 1 nautical mile to its side, it would probably have been the Myoko that was hit this time.
"Submarine, it's the Renaissance Army's submarine, damn it!
Find it out, find it out!"
Captain Yoshikawa Masaru, the captain of the Myoko heavy cruiser, quickly realized that they were under attack by a submarine of the Restoration Army.
The sound of battle alarms rang out in all Fuso ships, and all sailors returned to their respective posts in an orderly manner.
The first thing they had to do now was to slow down, then turn on the hydroacoustic system to search for the Fusion Army submarines lurking in the sea.
"All torpedo tubes fired, targeting the large ship directly ahead."
Since the submarine force of the Restoration Army did not collect the voiceprints of the Fuso warships, it was impossible to identify the model of the ship without using a periscope.
However, the approximate tonnage of a ship can be determined by the noise it emits.
For example, there is a large ship in front of them that is at least 10,000 tons.
This must be the heavy cruiser of the Fuso anti-submarine fleet.
So Qi Hong decisively seized this opportunity and directly fired all four torpedoes.
After all four MK35 torpedoes were released, Qi Hong decisively ordered: "Emergency dive, diving depth 200 meters."
Generally speaking, the depth of depth charges is above 150 meters, so a depth of 200 meters is relatively safe.
When the UH-1108 nuclear submarine was diving urgently, four torpedoes hidden in the ocean were approaching the Myoko heavy cruiser at the fastest speed.
However, at this time, a light cruiser named Natori was heading towards the Mizunoe with a Type 4 hydrophone system.
Its noise directly attracted two MK35 torpedoes, leaving only two still sailing straight forward.
"Torpedoes, two torpedoes spotted at 14 o'clock on the starboard side, 1 nautical mile away!"
Although the MK35 torpedo did not have an obvious track, the sentry post at the top could see two dark shadows under the sea, and it was not difficult to determine that it was a torpedo.
When the captain of the light cruiser Natori heard about the torpedo, his heart was in his throat.
But when I heard there was still 1 nautical mile left, I relaxed again.
At such a long distance, they can avoid it by simply changing course.
So the captain said calmly: "Right turn 30 degrees, it's in that direction, go find it!"
From the direction of the torpedo, the captain immediately determined the approximate direction of the Restoration Army submarine that ambushed them.
Immediately, the light cruiser No. 6000, completed a turn at sea and headed directly towards the direction of the incoming torpedo.
However, the next words from the sentry made him feel scared.
"Report, the torpedoes have turned and are coming towards us!"
"Nani?"
The captain's face was filled with disbelief when he heard this, and he used a telescope to look in the direction of the incoming torpedo.
Sure enough, when they turned, the torpedo also turned, as if it was watching them.
"Damn it, right rudder 20, get out of their way!"
However, the torpedo then turned in the direction they turned the rudder, which made the captain's heart sink to the bottom.
"Baga, there are people on their torpedoes. They are suicide torpedoes!"
This scene made the captain's mentality collapse.
They turned and the torpedoes turned with them. It was obvious that these two torpedoes were manned.
At least that's how it seemed to him, how else could he do it?
Under the desperate gaze of the captain of the light cruiser Natori and a group of informed sailors, no matter how they maneuvered, they could not avoid the two torpedoes that had locked onto them.
"Shoot, fire all your shells at them!"
When the torpedoes were only a few hundred meters away, some people finally recovered from their panic and fired at the two torpedoes.
In an instant, dense shells fell around the two torpedoes and exploded, attempting to intercept the torpedoes in this way.
This is their last hope.
However, their hopes were doomed to fail.
Because their interception ended in failure, two MK35 torpedoes had a close encounter with the port side of the Natori.
When two heavy torpedoes penetrated the bottom of the ship and exploded, the only outcome was sinking.
Accompanied by a loud noise coming from the bottom of the ship, the light cruiser Natori also suffered the same fate as the destroyer Mizunoe.
Although it was not sunk directly due to its larger size and more watertight compartments.
But the two huge holes on the port side meant that it had entered the countdown to sinking.
Under the billowing smoke, the Mingri ship ultimately could not escape the fate of sinking.
However, before the Fuso anti-submarine fleet could recover from the shock of the sinking of the light cruiser Natori, the heavy cruiser Myoko was also attacked.
