The Nagato class battleships were the pride of the Japanese and the navy.
Ever since the end of the First World War, the concept of victory with giant warships and cannons had been deeply imprinted in the minds of the Japanese.
The longgate-class battleship was born under such a concept.
On November 25, 1920, the first ship of the Changmen class, Changmen, was delivered.
It became the first battleship in the world to use a 410mm caliber main gun, and also the first battleship in the world to have a speed of more than 25 knots.
It allowed the navy to make a name for themselves internationally.
It also brought them supreme glory.
These two ships with a displacement of more than 32,000 tons became the sustenance of the navy's spirit.
Daisuke Sugibanji Jiro was the captain of this giant ship.
At this moment, he was leaning against the railing outside the commander's tower, admiring the sea that he had long been tired of, blowing the unpleasant sea breeze.
The vice-captain came to his side and sighed."" I didn't expect that our first combat mission would be to bombard Jinzhou instead of fighting the enemy ships on the sea. The people on the Luao are going to laugh at us.”
This was the first battleship of the Longgate-class battleship, Longgate.
"Battleship, do we still have any opponents in Asia?"
Do you think that the Chinese navy would dare to send their small boats to fight with us?”
After saying that, the two of them could not help but laugh out loud.
His tone was filled with arrogance and disdain.
Of course, they had the right to be arrogant.
They had studied China for many years and were very clear about the current situation of the Republic of China Navy.
So far, the total displacement of the entire Republic Navy was only about 30,000 tons.
The largest battleship was still the Ninghai Light Patrol, which had a displacement of more than 2900 tons.
At this moment, the two people who were chatting did not know that danger was approaching.
The Type-21 submarine was still very quiet.
Of course, by the standards of the future, it was even louder than a tractor on the sea.
However, in this era where sonar had just been equipped, it was very difficult to find a Type 21 submarine in a silent state.
Moreover, the navy did not even have much sonar equipment.
Anti-submarine could only rely on listening devices.
Moreover, they did not pay much attention to anti-submarine warfare, just like anti-air warfare.
" Captain, we're one kilometer away."
After two hours of sailing, the Type 21 submarine had entered the attack position.
The distance was only one kilometer, which was very close for the Type 21 submarine.
Moreover, in order to deal with the Japanese warships, they had specially prepared a secret weapon before setting sail.
That was the T5 sonic homing torpedoes.
It could start searching for the source of the loudest noise 400 meters after launch, and its accuracy was still very good.
Even though the sonic homing of this model of torpedoes was not that reliable.
However, the T5 torpedoes were effective against the huge sound source of the Longgate battleship.
Moreover, the T5 Torpedo not only had a sonic homing guidance method, but it was also an electric Torpedo with a small track that was difficult to detect.
Its performance was also very good. Not only did it have a range of 5.7 kilometers, but it also had a speed of 24 knots.
In this era, this speed was considered very fast.
Xu Hai's eyes turned sharp when he heard this.
Sonar acquiring shooting elements."
In less than ten seconds, the Sonar Soldier nodded to Xu Hai to indicate that the input was complete.
The firing data of the Type-21 submarine could be automatically input through the sonar without having to rise to the periscope.
"Tubes 1-6, fire in a fan-shaped salvo.”
"Fire!"
As the flip cover of the submarine opened, T5 torpedoes with a caliber of 533mm entered the ocean.
With the activation of the tail motor, six torpedoes pierced through the sea and pounced on the Longgate battleship.
A distance of one kilometer only took a minute for a 24-knot torpedoes.
Xu Hai looked at his watch and started counting slowly.
After the six torpedoes sailed for 400 meters, the sound guidance device began to work.
He began to collect the noise in the ocean.
The Longgate, which was the largest battleship, immediately became their target.
After locking onto the target, the torpedoes adjusted their direction slightly and rammed straight into the Longgate.
Sugiban Tetsujiro and the vice-captain, who were bored and chatting, noticed the incoming torpedoes on the right almost at the same time.
"Eh? Is that a school of swordfish?"
The vice-captain looked over curiously when he saw the six black shadows approaching quickly from the deep blue sea.
Shanbanti Jiro was extremely puzzled.
Normally, the school of fish would stay far away from the noisy fleet. How could they approach them at such a high speed?
Hence, he leaned out and took a closer look.
Even now, they still didn't realize that it was a torpedo.
This was because the thermal torpedoes now had a large tail and could be discovered from a long distance.
The world's first electric torpedoes without tow lines were developed by the German Navy in the 1930s.
When the distance was less than 200 meters, Sugiban Tadaijiro finally saw what it was.
When he saw the six cylindrical bodies with unnoticeable trails at their tails, his pupils constricted.
"Torpedo!"
A mournful cry that had already changed came from his mouth.
This roar instantly caused the entire Longgate battleship to explode.
After shouting, Sugiban Ichijiro rushed to the driver's seat without a care.
However, the torpedoes did not give them any time to react.
A 200-meter distance only took 15 seconds for a 24-knot speed torpedoes.
When Little Tian controlled the Longgate to evade the attack…
The T5 torpedoes had arrived.
The first T5 Torpedo hit the Longgate.
The T5 torpedoes with a fixed depth of 12 meters passed directly under the side of the Longgate.
When they reached the bottom of the Longgate.
The magnetic fuse of the T5 Torpedo was activated.
"Boom!"
A huge amount of energy was emitted from the combat unit.
A large amount of high-temperature and high-pressure gas rapidly expanded, easily tearing through the Longgate's bottom armor.
This was the position closest to the warship's dragon bone.
Under the huge explosion, even the Longgate, which weighed more than 30,000 tons, trembled violently.
Then, the second, third, fourth, and sixth shot hit their targets.
For some reason, the fifth torpedoes did not trigger the fuse and passed through the transmission line.
These loud sounds were like a heavy drum beating in the hearts of the navy.
