At 4 pm on May 19, 1029, the steam calendar, Bing Nuclear arrived at the coast again. In the process of returning to the coastline, Bing Nuo, who was sitting on the train, frequently communicated with the sea crab harbor by radio waves.

However, the submarine formation that was fully on standby in the Sea Crab Harbor quickly began its operations after receiving the nuclear order. The submarine almost came out.

In this battle, the submarine took the initiative to attack on the 19th because of technical limitations.

Two years ago, Binghei ’s submarine program in West was aimed at 400 tons of technical parameters. But in fact, due to the poor industrial foundation of West, the workers' proficiency is not high. At the beginning of 1029, the workers in the sea crab harbor had only mastered the manufacture of two hundred tons of submarines.

There are only three 420-ton submarines in the entire Westport port. The three large-tonnage submarines passed after repeated inspections by Blue Inch. Without the technical guidance of the mechanical controller, the workers in the sea crab port will not be able to master the manufacture of larger tonnage submarines in the short term, so they can only produce small submarines with a mass of more than 200 tons.

And what is the difference in combat power between more than 200 tons of combat submarines and more than 1,000 tons of combat submarines? In fact, as long as they can reach the combat position to dormant encounter enemy ships, they will pose a huge threat to surface ships.

More than 200 tons of combat submarines are more difficult to find due to their low tonnage and low noise. In World War II, many small submarines achieved good results.

However, the range of more than 200 tons of submarines is too short, which makes it impossible to deploy in the ocean and can only be used for offshore defense. The sea crab harbor's more than 200 tons of combat submarines have a self-sustaining force of ten days, and full combat is considered fifteen days.

In the calculation based on the audit, the commander assigned the submarine with only five days for the mission. The rest of the time must be left to the captain of the submarine, so that the captain can take the whole boat safely home.

Due to the limitations of the small submarine itself and the boldness of its nuclear strategy, it paid special attention to the movement information of the Oka fleet in the battle.

At a critical time, in a critical sea area, a sufficient number of submarines must be deployed to give the enemy a deadly ambush.

[7pm on the 21st. Bingnu arrived at the Shuangqiu coastline. 】

In the temporary base on the hill, Dustgar is working hard for a nuclear fan.

Because of the need to observe the smoke column of the Oka steam fleet on the sea, Bing nuclear expanded the field to fifteen kilometers every fifteen minutes. The increase in body temperature forced Bing nuclear to take off the mechanical clothes and wear a thin summer dress, but the whole body The temperature is still a bit high. Under the bright red skin, the veins flickered, and Dustgar kept staring at the phenomenon on Bing Nu's body.

At this time, Bing nuclear looked at the battle map with great concentration, picked up the pen to mark the position of the fleet on the map again, and then operated the radio wave to send the signal in the sky with the field.

These markers show the departure track of the Oka Steam Fleet on the map, and the track that extends on the map will eventually enter a red circle on the map.

The location of the red circle-Hukou Strait.

The Hukou Strait is the junction of the world's Mediterranean and Northwest Ocean. When the Okaks rose up nine hundred years ago and controlled this golden waterway, they built maritime forts on both sides. There are a total of fifteen super artillery pieces in the maritime fortress, with a powerful range that can block the narrowest 50 kilometers of the Hukou Channel. Since then, no fleet has been able to seize control of the Okaks in this important strategic position.

However, it seems that it is precisely because the Houkou Strait is an absolutely safe area in the eyes of the Oka people. The large fleet of the Oka Empire did not enter the war zone when passing through it.

At 11 pm on the 21st, eight steel battleships with a tonnage exceeding 10,000 tons and a steel array of thirty-two small warships of various types reached the east side of the Hukou Strait. The boiler in the battleship turned on the horsepower to drive the ship's shaft, and a fleet of 10,000 tons split the waves in the sea water. At the rear of the battleship, the white water spray separated on the sea surface, dragging dozens of kilometers of long wave spray. The battleship chimney spewed out a plume of smoke at the same time. The industrial beasts all the way down, shining the empire's force.

After seeing the big fleet's track four hundred kilometers away, Bing nuclear immediately sent the information to the front line through the high-altitude airship, and a submarine on the front line released the communication buoy on the sea received the information.

After the entire submarine group received important information about the number of Oka fleet, the order of the fleet, the formation through the strait, the diesel engine went out, the ventilation ducts were turned on, and the electric motor was turned on.

The underwater fleet began to coordinate by means of underwater sonic codes, and soon formed several strike formations.

[The sailor has new magic to discern sounds in the sea, but this skill of the sailor is a skill of the sailing age. 】

However, the times are advancing. There is no ship engine in the sailing era. In the steam age, sailors stood on steam power and used new magic. They could not hear the submarine at all. Because the noise of the propeller of the ship where they are located is already extremely loud, this is equivalent to sitting on a tractor that is started, and cannot hear the voice of a few meters away.

At present, most civilian sea and fishing boats are still sail-powered. Sailors generally do not eliminate this skill, but they are not very useful on steel steam-powered ships on the battlefield.

There are only two techniques to detect underwater submarines:

First, destroyers and frigates use a line of sonars to keep towed sonars away from their own noise sources in order to detect underwater.

Second, a large number of anti-submarine aircraft, a wide range of sonar buoys. Once the submarine floated, the buoy immediately sent a signal, and the anti-submarine aircraft flew over.

Of course, neither of the two sets of anti-submarine systems had Okas, so they ran into the sea wolf mode carefully prepared for them.

A year ago, after learning about the underwater threats and seeing the shortcomings of submarines in the report, Oka ’s naval bureaucrats thought that their scope of application was extremely small, and that the West ’s own forces only used submarines as a means of intimidation. These naval bureaucrats fled aside with a smile, never thinking of formulating a plan to deal with special situations that might occur in some cases.

The inaction of bureaucrats in the past has caused serious consequences today.

At 11:34 on May 21st, Archduke Lantao stood on the bridge of his battleship, and started to look around. He was so upset tonight that he couldn't sleep, so he walked up to the bridge to work as the foreman of the fleet.

Looking at the undulating sea surface at night, listening to the sound of the waves hitting the bow of the ship, the grand-prince Lan Tao fell into thought.

"The inner spherical area with a radius of one kilometer and an observation range of twenty kilometers is the standard fortress. In the past century, with the emergence of long-range weapons, the fortress has gradually become less effective than generals and powers. Austria The empire of the Ka Empire collectively chose to combine with battleships, using the battleships of the battleships, armor and the unique maneuvers of the ships to defend the status of the fortress profession. This is so. In the eyes of many nobles on the mainland, the decline of the fortress has become a trend.

But now, the maverick child mocks us fortresses with his own amazing action, and we have shortsightedness in industrial technology. "

"Electronically Controlled Airship"

"Remote Warhead"

"Electric remote control drone"

Grand Prince Lan Tao meditated on the new things that appeared in the war. His keen political thinking associates many aspects.

"In the next two decades, there will be huge changes in the military technology of the mainland. The fortress ’s combat power will increase dramatically, so the matching political rights will also increase substantially. By then, the fortresses will not have to rely on fleets, fortresses, or military cores. , Guaranteeing political status. Then ... "

Grand Prince Lan Tao's eyes lit up. He held the battleship's main gun and patted it towards the gun barrel. Suddenly, Yu Guang saw several direct sails in the distance. The archduke was suddenly surprised, he opened a number of visual observation magic, and carefully observed the sea.

A few seconds later, the Grand Duke sent a communication alert to the surrounding fleet through the field: "Attention! Full fleet, attention! Torpedo! North side! There are six!"

The way to defend against mines is to reduce the speed of the ship or even stop the ship to search for the sea surface. The water current made by the water gun blows the mine away and then detonates with a machine gun. The defense of torpedoes is to increase the speed and then use large steering to avoid it. Therefore, when encountering torpedo attacks, the fleet formation will change rapidly.

When the wolves are hunting, they often like to have one or two wolves launch an offensive attack on the side, and expel the target to the position where their teammates ambush.

The torpedo seen by the Grand Duke Lantao was launched by the attack group of four submarines.

Because surface forces do not know the underwater situation when they encounter an attack, the first reaction is often to steer and avoid according to dogma.

When the torpedo fired in the offensive direction successfully attracted the attention of the Oka fleet, a large number of destroyers maneuvered to the side where the main battleship was attacked, trying to help the main battleship block the mine. The captain (median professional) also instructed the crew to observe the distance.

It's just that they don't know. In fact, the real deadly threat to the Orka fleet is on the other side.

A large number of submarines that gathered up ventilation ducts and advanced purely on batteries formed hunting formations, waiting silently for the Imperial fleet formation to approach the ambush circle.

Compared to the first wave of torpedoes with obvious trajectories, the main submarine hunted by this wave uses silver-zinc battery-powered wire-guided torpedoes. It weighs 1.5 tons and has a warhead of 300 kilograms. It is a heavy weapon that can be killed in one hit. There are no air bubbles and the track is highly concealed.

Fifteen minutes later, when the first group of torpedoes were avoided by the fleet.

The Grand Duke Lantao paced on the wooden deck of the battleship (the wood is still a steel shell, the wood is for sun protection). After the torpedo attack, the Grand Duke Lantao constantly observed the surrounding situation in the field.

Historically, the entire Hukou Strait has not suffered any attacks for three hundred years. Lookout towers and turrets on both sides can block the fleet. However, Oka has been attacked by torpedoes in this seemingly completely safe area. This made Grand Tao Lantao restless.

"He is a fortress, but also an amazingly talented mechanical controller." The Duke Lantao inside the bridge repeated this sentence, wanting to wake himself up through this sentence, and don't ignore any important things.

From time to time, he looked up at the sea. But in the misty sea at night, the fortress didn't notice the hidden periscope in the waves.

Duke Lantao began to focus on his underwater situation within a kilometer.

Suddenly, the fortress face was astonished, and his field found that three torpedoes underwater had suddenly entered his area. And these torpedoes approached the battleship.

Note: If there are information display devices at each work position on the ship, Commander Lan Tao will accurately and clearly transmit the information seen in the field to the position of the secondary gun. room.

At present, the silver-zinc battery torpedo has a very small water surface track, which can only be found in the fortress area, and it is difficult for soldiers at the position of the secondary gun to see it. Even controlling the artillery did not hit the correct position.

Finally, in the last minute before the impact, the sailor waited until the torpedo exploded while the fortress kept screaming and yelling in front of the sound tube.

With a bang, the whole hull seemed to be arched by an undersea monster. With a loud noise, a huge cavitation bubble rose from the water.

The side of the ship exploded, and huge waves crashed onto the deck. The ship trembled violently, and all the soldiers on the deck fell because of vibration.

The Duke took a few steps back on the deck and immediately stood still. After standing still, however, he came to the freeboard and looked down at the side of his battleship. He saw that the absolutely circular surface tremor area was slowly spreading, while a huge fissure of nearly ten meters was ripped from the side of the ship, and the sea was pouring into the middle of the ship.

Just as the Grand Duke Lantao looked down at the influx of water flowing under the ship, an explosion flash appeared at a distance of 1.5 kilometers on the left side, causing the Grand Duke to immediately look up in that direction, where there was another battleship. s position.

With the sound of the explosion from that place, Grand Prince Lan Tao turned abruptly and pointed to the northwestern land. Anxiously, he scolded the air and said, "The gun flame is nuclear, you, you!"

The sailor on the side hurriedly pulled the emotional granddaughter off the freeboard.

[Steam calendar at 2:00 on May 22, 1029]

West used a total of 43 submarines of various tonnages to ambush the Orkas' Mediterranean reinforcements in the North Sea near the Houkou Strait.

As a result of the first wave of torpedo attacks, four battleships were severely damaged, two of which sank directly, and the remaining two keels were cracked, and returned to the port was also scrapped.

At the same time, a 5,000-ton heavy cruiser and a troop carrier were hit.

Later, during the entire fleet search, it touched the mines released by four submarines, and three destroyers sank to the bottom.

Including a fort, 127 professionals died in the attack. This is the biggest loss of the Oka Navy in 300 years.

West had no casualties in the battle. The only loss in this military operation was that the interior of a 200-ton submarine was returned to the sea due to improper flush toilet operation, which caused a large number of flooding inside the boat to be abandoned.
