After discovering the target and positioning it, the xxi submarine immediately put away the vent pipe and used silent speed to penetrate the escort area of ​​the Japanese transport fleet, and then set up a net to wait for the Japanese escort fleet to come to the door.

"Yoxi, what a quiet morning! This is really a lifeless escort mission!"

The captain of the Yangyan-class destroyer, Major Salvaro Huangti, stood by the side of the ship, facing the rising sun in the east, stretched comfortably and sighed in vain.

As a new destroyer at the beginning of war, the Yangyan class is the best-built destroyer of the Japanese Navy. Its speed, range, firepower and hull stability are excellent, and its comprehensive performance is above the destroyers of various countries.

Although due to the common problems of Japanese destroyers, Yangyan-class destroyers did not have radar when they were built, their sonar equipment was poor, and their air defense capabilities were weak, with the development of radar and sonar technology, these shortcomings were gradually made up.

The design of the Yangyan class is largely due to the previous full-tide level, and the two-level ships are very similar in shape.

The destroyer has a full load displacement of 2,490 tons, a length of 118.49 meters, a width of 10.82 meters, a draft of 3.76 meters, a maximum speed of 35 knots, a maximum range of 6,000 nautical miles, and a crew of 239 people.

Weapons are equipped with 6 127mm main guns, Type 92 4-mounted 610mm heavy torpedo launch tubes, Type 93 oxygen torpedo, and equipped with mine-branching and mine-sweeping tools, torpedo reloading devices, and two single-barrel 25mm anti-aircraft guns.

With the change of the war situation, from 1942 to 1944, most Yangyan-class destroyers were dismantled and the main turret increased to 28 air-defense guns. In addition, four 12.7 mm anti-aircraft machine guns were installed.

The mine-branch and mine-sweeping tools at the stern of the ship were also removed and replaced with four deep-water bomb throwers.

With these changes, the positioning of the Yangyan-class destroyer is more in line with the actual needs, and its air defense capabilities and anti-submarine capabilities have been greatly enhanced.

As the main destroyer of the Japanese Navy, a large number of Yangyan-class destroyers performed well in the war and participated in Pearl Harbor sneak attacks and almost all naval battles.

Because of this, the Yangyan-class destroyer suffered great losses. After surrender, only one Xuefeng was left, which was delivered to the Kuomintang Navy as a compensation ship.

This Japanese destroyer, the best performing Japanese destroyer, experienced countless tragic naval battles from beginning to end, including the Okinawa special attack with the Yamato battleship, which was not damaged. It was known as the "Immortal Bird" and the only one survived after the war.

When the Kuomintang Navy retired, the Japanese people wanted to buy it as a commemorative ship, but were rejected and eventually disintegrated.

The Mochizuki destroyer, also known as the Yangyan destroyer No. 2, was hit on the starboard side of the Mochizuki to the first boiler room and was on the verge of sinking during the Battle of Midway last year.

Later, after emergency repair, the ship retained its buoyancy and was finally dragged away by the "Maihe". The rescue team completely destroyed its first chimney to the front half, cut it off, and dragged it back to the Japanese Maihe Military Port.

In October 1943, the destroyer of the Burning Fire was completely restored and returned to the front line.

As the Allied submarine forces became increasingly active, the rear sea routes were attacked more and more frequently. Since January 1944, the Uchihatsu destroyer "retreated to the second line" to serve as a transportation escort mission in Guam.

"Yes, such a journey is too monotonous and lonely. I miss the good days that were circling the sea!"

The first mate Takano Narimi, who was standing aside, was also quite emotional.

Although they know that the Japanese Navy is now declining and is in a downward trend, these Japanese Navy still feel good about themselves and are still immersed in the brilliant victory of the Japanese Navy a few years ago.

However, there is a saying that is good, pretending to be struck by lightning!

"Not good!"

"The big thing is wrong, torpedo attack!"

"In the port side of the bow, there will be torpedo attacks!"

Just as Arati Saburo and Takano Narimi sighed and thought it was a waste of talent to bring them to the rear to perform the escort mission, a Japanese crew member suddenly shouted loudly in horror.

"Nani? Torpedo attack? Why did there be a sudden torpedo attack? Why did there be no sign in advance?"

Huang Tisanro was stunned. This was a slap in the face. His own destroyer was equipped with the most advanced radar and sonar system, and his specialty was anti-submarine work.

But now, in broad daylight, enemy submarines are coming to attack them directly?

"Baga, are you wrong? In this case, aren't they seeking death? "

Huang Tisanro was not only confused, but also very puzzled, because in his current perception, the submarine and destroyer were completely the existence of grandfather and grandson.

That's right, when a submarine encounters a destroyer, it is basically only necessary to escape. Under normal circumstances, it will never choose to carry out frontal hard work in broad daylight.

First of all, destroyers have fast speed and good maneuverability, generally above 30 knots, and their maneuverability is obviously much better than those of submarines. They can even avoid the attack of submarines before counterattacking.

Secondly, World War II submarines do not have deep-sea attack capabilities and must float to the surface when attacking targets, making it difficult to hide their bodies.

Therefore, if a submarine wants to attack a destroyer, it can only have a vertical course, or budget the other side's course and perform a 90-degree strike, so as to increase the hit rate of the attack.

Otherwise, at the speed of the destroyer, you only need to easily swing your tail to avoid torpedo attacks.

On the other hand, once the submarine is exposed, it will basically only become a lamb to be slaughtered. The destroyer has a super fast maneuver speed of more than 30 knots, and it can kill the submarine just by going around.

Because the submarine is very noisy and is slow underwater, the underwater submarine has a speed of around 10 knots and is not strong enough to float to the water surface to ventilate frequently.

This leads to the disadvantage of insufficient endurance of submarines. Destroyers only need to determine the area where the submarine is active and wait for a period of time in this area.

Submarines can be said to have almost no extra road to go besides the two choices of fighting to the death or surrendering to the surface.

Although he had a hundred thousand whys in his head, Huang Tisanro did not move slowly at all. He quickly followed the direction pointed out by the Japanese observer not far away.

"Nani? What torpedoes are so fast? And so many?"

However, he didn't know it without looking. When he saw it, he was shocked. Huang Tisanlang was shocked to find that there were no less than 5 torpedoes in the vertical direction of the hull that were hitting the destroyer head-on at an extremely fast speed, completely blocking all the space where the destroyer was moving around.

"Baga! How could this happen? What are the radar soldiers and sonar soldiers doing for food? Why didn't they notice a little movement in advance?"

Seeing a vast number of torpedoes coming, Takano Narimi's smile instantly frozen on her face, replaced by a face full of horror and despair.
