At night, in the outer seas of the Huludao Island.
"Boom! Boom! Boom!"
The ship roared as six Type 21 submarines sailed on the calm sea.
The submarine with the number 9001 was also the headquarters of the brigade, and the captain was Xu Hai.
"Everyone, according to the original plan, we will form groups of two and patrol the Bohai Bay and the Yellow Sea to find fighter planes.
I repeat, as long as it's a ship with the Japanese flag, be it military or civilian, sink it.
I wish everyone good luck. Boat No. 2 and I will be leaving first.”
The average depth of the Bohai Sea was only 18 meters, which was not very suitable for submarine operations.
Apart from one team, the other two teams would head out of the Yellow Sea to search for the target.
It was enough to leave two Type 21 submarines in the narrow Bohai Bay.
Soon, Xu Hai's submarine quickly dived and traveled at a speed of 12 knots under the sea surface.
The environment inside the submarine was very humid and oppressive, and the bed was extremely small.
If one were to talk about the most difficult and tiring military, then the submarine soldiers would definitely be at the top.
But at this moment, the morale of the soldiers was extremely high.
Piloting a submarine that far exceeded the technology of the current era, they were very confident in this mission.
Moreover, Xu Hai had even organized a competition within the brigade.
This time, the group that sank the least would have to wash the clothes and socks of the group that sank the most for a month.
After driving for a long time, a submarine soldier came to his side and said,"Captain, we have already left Bohai Bay and entered the Yellow Sea.”
Xu Hai opened his eyes and a cold light flashed in them.
"Then let's get to work. Go to this place. This is the sea route from the Japanese to Lushunkou. There must be a lot of big fish.”
After driving for about a day, they arrived at the sea area about 150 nautical miles northeast of Weihai.
Merchant ships from various countries could often be seen passing by here.
There were also some Japanese merchant ships.
However, Xu Hai was not in a hurry to make a move. If he alerted the enemy, he would not be able to catch the big fish.
When the big fish didn't dare to stand out, they would attack the small fish.
A few hours later, the sonar detected a large fleet.
However, when he raised his periscope, he saw warships flying the John Bull flag. There was even a cruiser among them.
"These foreigners will pay the price sooner or later.”
Xu Hai gritted his teeth as he looked at the John Bull warships through the periscope.
The foreign warships sailed freely in China's territorial waters.
This was a great humiliation for the navy.
"Hovering, deploy the radar antenna.”
After confirming that John Bull's fleet couldn't see them.
The Type-21 submarine floated to the surface again.
At the same time, the FUMO-84U1 radar equipped on the Type 21 submarine also began to work.
Although the radar could work in the periscope state, it was enough to provide early warning to prevent them from being discovered.
Therefore, Xu Hai still chose to float up to get some fresh air.
The Type-84 radar could detect up to 20 kilometers of the sea. It was completely incomparable to the radars of the later generations, but it was definitely black technology in this era.
During the voyage, the radar soldier in the radio room suddenly shouted,""Report, signals from a large fleet have been detected. There are a total of six sources, and one of them is a large ship.”
Xu Hai quickly came to the radio room and said,"Report your position, bearing, and speed.”
"Bearing 13, position 20 kilometers, speed 18 knots.”
"Emergency dive! Everyone, get into your battle stations!" Xu Hai shouted immediately.”
Soon, the huge submarine disappeared from the sea.
"One-third ahead starboard, set depth 8, speed 6.”
"Yes, right helm, advance one-third, set depth 8, speed 6.”
" Everyone, maintain silence."
Under Xu Hai's command, the Type 21 submarine quickly occupied the T-shaped attack position.
According to the target information detected by the radar, it was very likely that they had caught a big fish this time, and it was a real big fish.
Generally speaking, the speed of merchant ships was only between 8-12 knots.
Even if there were high-speed merchant ships, it was impossible to sail at 18 knots.
It must be a military target.
And on this route, there was at least a small probability that it was the navy of Xiaotian.
According to the signal characteristics of the radiation source, the target this time was not small.
More than half an hour had passed, and the radar had been locked onto the target.
"Raise the periscope.”
A periscope rose from the surface of the sea, and Xu Hai looked over.
Soon, they found their target on the rolling sea.
"Hiss!"
It didn't matter if he didn't look, but he was shocked when he saw it.
About four kilometers away from him, there were six warships, five small and one large.
The flag hanging on the warship was the Sun Flag of Little Day.
The largest warship was sailing at the front.
On the bow of the ship, there was an exceptionally eye-catching golden chrysanthemum.
This warship was one of the Nagato class battleships, known as the symbol of the Japanese Navy.
He just didn't know if this was the Changmen or the No. 2 Luao.
"A big job is coming. But why would the Japanese's long-gate battleship run to the Bohai Sea? could it
Not good, these bastards are definitely coming for us.”
At this moment, the longgate-class battleship appeared strangely.
Without a doubt, they were targeting the border guards.
"Even if it sank, we have to beat it up.”
Xu Hai immediately made up his mind.
"Set a depth of 40 meters and proceed at a silent speed.”
After hearing this, everyone's eyes burst out with a strong fighting spirit.
Even though they knew it was dangerous to do so, this was a battleship.
If they could sink this battleship that weighed tens of thousands of tons, their entire ship would go down in history.
Moreover, as submarine soldiers, they had already made up their minds to die.
Every voyage could be their last.
Although the silent speed was relatively slow, it allowed the Type 21 submarine to safely approach the Japanese fleet.
At this moment, everyone only had one goal in their eyes, and that was the longgate-class battleship.
