Iron-blooded Hero Li Yunlong

"Roms!"

Immediately, a destroyer, three gunboats and two coastal defense ships began to drive towards Qianlong's submarine.

It can be said that the submarine is a bit like a sniper in land warfare, buried in the shadows, waiting to deliver a fatal blow to the key target.

Just when Ersanlang by the river sent warships to attack the Qianlong, the Qianlong fired another six torpedoes and hit two coastal defense ships.

"Boom...bongbongbong..."

Suddenly, intense flames and explosions ignited on the surface of the sea, and then the two coastal defense ships began to sink slowly on the surface of the sea.

This is the power of submarines, killing people invisible.

Seeing that two more of our own warships were killed by Li Yunlong's submarine, this made those warships on the sea even more anxious, and they were searching for the Qianlong submarine, looking for the target!

During World War II, due to the backwardness of technology, many counterattack technologies were very backward and blind.

To deal with nuclear submarines, it is nothing more than the way of hitting: throwing depth charges.

Depth bomb, also known as depth bomb, is an underwater weapon used to attack submarines. It is usually equipped with a fixed-depth fuze. After being put into the water, it sinks to a certain depth or detonates when it is close to the target to kill the target. It is usually launched by a ship or an anti-submarine aircraft. .Deep bomb anti-submarine has always been the most important anti-submarine means.

The second is to launch torpedoes and anti-submarine torpedoes.Anti-submarine torpedoes are self-guiding torpedoes designed to attack submarines.It's just that the torpedoes of World War II were very backward, and the attack effect was not ideal.

The last thing is to deploy mines.Sea mines are pre-released in the water, and can be triggered when a submarine contacts. During the attack, the submarine channel can be blocked and the actions of enemy submarines can be restricted.

Another last resort is to directly hit the submarine with the ship.Although this is dangerous, it is a very practical anti-submarine method, especially for destroyers and frigates, the mortal enemies of submarines. Because of their hard and sharp bows, submarines are basically difficult to parry. Smashed in two and buried at the bottom of the sea.

However, nuclear submarines basically do not need to show their faces to charge, so this trick is useless.

In Qianlong.

With so many Japanese warships approaching him, Li Yunlong certainly understood something.

"Master, there are a lot of red dots on the radar panel, and the enemy warship is rapidly approaching us."

Li Yunlong looked at it, and said with a slight smile on the corner of his mouth: "Very good, just relying on this diesel-electric engine to compare with my nuclear power? It's really ridiculous!"

"Immediately aim at the frontmost target, launch a torpedo and kill him!"

"Yes!"

Although these warships are constantly approaching Qianlong, Li Yunlong has no fear at all.

"Lock the target!"

"Torpedo reload!"

"emission!!"

Immediately, three torpedoes were quickly ejected from Qianlong, and headed directly towards the destroyer rushing to the front on the sea!

"Whoosh, whoosh, whoosh, whoosh, whoosh..."

This torpedo is flying fast on the ground, at an extremely fast speed of 660!Brought up a burst of blisters.

A moment later, the torpedo perfectly hit the front destroyer, and there was a sudden explosion.

"Boom...bongbongbong..."

In an instant, the entire destroyer burst into flames and black smoke, and then sank slowly.

Killed another destroyer!

At this time, the Qianlong submarine was getting closer and closer to the Japanese warship team. If the Japanese warship dropped depth charges at this time, it would be very dangerous for the submarine!

At the moment, Li Yunlong said to the helmsman unhurriedly: "Speed ​​up the speed immediately and avoid these warships!"

Nuclear-powered submarines have a very obvious advantage, that is, they are fast!

This is a real naval battle!

The corner of Li Yunlong's mouth curled into a faint smile: "Is the era of sea warfare coming? Let me use a nuclear submarine to have fun with you!"

PS: In the sixth update, I strongly recommend the bloody anti-Japanese book "Snow Leopard: War of Wolves". .

Chapter 674 Depth charges, speed is king (first update, please subscribe)

Seeing the remaining warships approaching him quickly, Li Yunlong didn't have any fear, because the Qianlong nuclear submarine had an unparalleled speed advantage.

"Boost!"

With the continuous manipulation of the deputy helmsman, the speed of Qianlong accelerated.

潜龙号的核潜艇速度大约是40节，1节=1海里/小时=1.852公里/小时，也就是74.08海里／小时。

That doesn't seem like a lot of speed, but it doesn't hurt without comparison.

The speed of Japanese warships is basically 25 knots, which is about 46.3 knots per hour. This speed varies greatly!

The speed of the Japanese submarine is even slower, basically only 15-20 knots, that is to say, the speed of the nuclear submarine is more than twice or nearly three times that of the Japanese submarine.

"Snoring...snoring..."

Qianlong accelerated.

Originally, the resistance to sneaking underwater is very high. After all, the entire ship is in the water, and it is already very fast to be able to achieve such a speed.

Because the destroyer at the front was killed, there are still three gunboats and two coastal defense ships chasing Qianlong.
