Pearl Harbor, located on the south coast of Oahu, Hawaii. The Pen, Fun, and Pavilion www.biquge.info is about ten kilometers from Honolulu, the largest city in the archipelago. The entire harbor covers an area of about ninety square kilometers and consists of three hidden bays that penetrate deep into the land. There is only one narrow entrance and exit to these bays, which is connected to the vast Pacific Ocean.

After years of excavation and exploration, the average water depth in this important military port is about 20 meters, which is enough to dock large warships of any tonnage. The harbor area has good concealment conditions and large room for maneuver in the waters, making it an excellent natural harbor.

Before it was annexed by the Ming Dynasty many years ago, the port was full of shellfish. The local Polynesian natives used to pick pearls here, hence the name Pearl Harbor. Now it has become the main anchorage of the Pacific Fleet of the Ming Navy, with numerous port facilities. Similarly, the headquarters of the Pacific Fleet is naturally located here.

"Knock knock!" The dull knock on the door was accompanied by shouting, so that Admiral Yunmo, commander of the Pacific Fleet of the Ming Navy, who had just entered his office and was making tea, almost gave his beloved teacup to the ground.

"Tell me, what's the good news that makes you so happy?" Opening the door to let the chief of staff with an excited face come in, Yunmo asked with a smile while pouring water.

"How do you know it's a good thing?" The chief of staff asked with a smile on his lips.

"Your mouth is going to go behind your ears, can't I see it?" Yunmo laughed and said, "Let's talk about it, let me be in a good mood all day today." ”

"Do you know Fang Renxu?" The chief of staff asked aloud.

"The ace captain? The one who killed Yamashiro and Shozuru? Yunmo raised his eyebrows in some surprise, "Can you be so excited, could it be that he has made another earth-shattering feat?" ”

"See for yourself!" The chief of staff excitedly handed the telegram in his hand to Yunmo, "This is the telegram I just received in the morning, and it was last night." Fang Renxu was besieged by the American destroyers, and he was not able to get out until the morning and sent a telegram back. As for the outcome of the battle, it has not yet been determined. However, if it is Fang Renxu, the credibility is still very high. ”

"Hiss~~~" Yunmo glanced at the telegram and suddenly raised his eyebrows, "Is this true?" ”

......

"Confirm! It's a large fleet! The experienced first mate took a closer look and confirmed that the shadow of the ship that appeared in the distance was a large fleet.

"Dive!" Without any hesitation, Fang Renxu immediately ordered the submarine to dive. They are submarines, and when they encounter an unidentified fleet on the sea, the first thing they need to do is dive, whether they are preparing to run away or to catch a handful. Concealment is the greatest advantage of submarines. A submarine that has lost this advantage is no match for a powerful warship.

"Can you confirm the ship's type?" When the Orca dived to the depth of the periscope, it began to move at a low speed of less than four knots towards the flotilla in the distance.

They are now located about four hundred nautical miles off the coast of San Francisco, California, on the west coast of the United States. During the day, they did not dare to show their heads because they were afraid of the long-range anti-submarine patrol planes of the US Navy, but at night they encountered a fleet when they floated up to recharge their batteries. The only flotilla that can appear in this area during this time period is the Americans. And most likely from San Francisco.

"At the head is a group of destroyers, followed by large ships, and they are very large." The first mate, who was lying on the periscope, said in a deep voice: "It is very likely to be a large battleship!" ”

"Are you sure?" Fang Renxu tried hard to suppress the joy in his heart, and asked out loud, "It's night, and there are no stars and moonlight here today, don't be mistaken." Maybe it's a big transport ship or an oil tanker. "In the era when there was no advanced radar, it was not easy to distinguish distant ships in the vast sea. There are often mixed oolong incidents.

"I'm sure it's either an aircraft carrier or a battleship that will follow!" There was a tremor of excitement in the first mate's voice, "And there is more than one!" One of the destroyers that took the lead was a large lead ship, which was a regular fleet, definitely not a transport fleet. And all of them are anti-submarine sailing! ”

"Great!" Fang Renxu slapped hard, "Finally, there is a big fish to eat, Lao Tzu has been waiting for a long time." ”

Unlike most submarine commanders, Fang Renxu prefers to attack regular warships with lethal weapons. In contrast to transports that have little resistance, these warships have the ability to destroy submarines.

However, with the courage of the artist and the new submarine with advanced performance in his hand, Fang Renxu has always liked to attack those warships. He believed that only an attacking warship would be able to demonstrate the true value of a submarine. He himself simply did not bother to attack ordinary transport ships.

"The opposite fleet is in a Z-shaped anti-submarine formation, and our angle is not very good. If you want to attack, you have to get ahead of them. The first mate got up and left the periscope, turned to look at Fang Renxu and said, "However, although the underwater speed of our new boat is much stronger than that of the previous submarine, it is not to the point where it can catch up with the surface ship at the underwater speed." There may not be an opportunity to attack this time. ”

"Can't catch up?" Fang Renxu squinted his eyes, lay on the telescope and observed carefully for a while, then turned around and came to the chart, picked up a ruler and pencil to scribble, and wrote.

A few minutes later, Fang Renxu threw down the pencil and ruler in his hand and said in a deep voice: "If it is a regular way, it is indeed impossible to catch up." We don't have a good angle. But there is another way for us to catch up, and we can even go out to the front of this fleet and ambush it. ”

"Oh?" The first mate was surprised and said, "And this kind of good thing?" ”

"That's right." Fang Renxu turned around and looked at his deputy with a smile: "Although the underwater speed of our new boat is average, its surface speed is very high." The fleet was in a zigzag formation, and it was just an ordinary cruising speed. It's not a difficult thing for us to ambush in advance. ”

"You want to float? Under the noses of the enemy?! The first mate had a ghostly look on his face. Isn't it looking for death to abandon the concealment of the submarine and float to the surface of the sea? You are a lookout post and radar sonar on the enemy's fleet, huh?

"I've been watching the weather all the time." Fang Renxu nodded, "There are no stars and moonlight tonight, there are no stars and moonlight, and it should rain in an hour at most." We can use this time to distance ourselves from that fleet. When it rains, their lookout posts will certainly not be able to see that far. We're a submarine, and the silhouette is very low, so it's really hard to spot in this night. ”

"What about sonar and radar?" The first mate asked suspiciously, "Even if a person can't see it, then the machine can't make mistakes, right?" ”

"The Americans' radar and sonar are not as good as ours, right?" Fang Renxu suddenly asked an off-topic question.

The first mate was slightly stunned, and nodded in response, "That's right, it's not to brag that their technology is still a little worse than ours." ”

"That's right." Fang Renxu smiled and said, "Our own radar and sonar will basically not be turned on if there is no alarm in this weather condition, because the quality is not yet to the extent that it can operate all the time." If we can't do it, those Americans can't do it. So there's a good chance that they won't turn on. After a pause, he added, "Even if the machine is turned on, it is not easy to find such a small target as us in the case of a stormy sea and rolling waves, and it is very likely that there will be a miscalculation." ”

"Okay." The first mate felt very helpless about Fang Renxu's bold plan, "Even if all these things you deduce are true, there is a premise that it really has to rain, and it must be as soon as possible, not more than an hour." Whether it's sailing maneuvers, adjusting the angle to enter a preset ambush zone or the time to exit the battlefield. All of this had to be done before dawn, and there was not much time. ”

It is only a short distance on the drawing, but in reality, it is likely to take a lot of time and effort. Bringing your own submarine to a predetermined area after precise calculations is not a simple matter.

"You can give it a try. It's only an hour in total, and if you don't succeed, you retreat. But if it really works. Fang Renxu narrowed his eyes slightly, and a flash of light flashed in his eyes, "Then we will make a lot of money." ”

If a submarine confronts a whole fleet head-on, it is looking for death. No matter how advanced the performance is, it cannot reach the level of a nuclear submarine. But if you instead ambush in the sea in bad weather conditions, things will be reversed.

Just as Fang Renxu predicted, when the Killer Whale submarine quietly dived in the direction away from the fleet for more than half an hour, the cloudy weather over this sea area finally began to fall dripping, and the rain became heavier and heavier.

The Orca quickly rose to the surface, turned on its diesel engine with the help of its low silhouette, and began to increase its speed, running around the distance to ambush the American fleet. And along the way, he was not discovered. Good luck strikes.

That is, this American fleet has been sailing in strict accordance with the Z-shaped route, wasting a lot of time, otherwise the Orca will not be able to catch up even if it performs well, let alone ambush in advance.

"Maximum power output!" Although he tried his best to maintain the expression on his face, the slightly upturned corners of his mouth had already betrayed Fang Renxu's mood at the moment. He had a hunch in his heart, and this time it seemed that he was going to catch a big fish again! And that's what he likes to do the most!

"Dive!" Finally, after several hours of maneuvering around the far edge of the fleet, the Orca finally came to the best ambush spot that the American fleet must have passed through and was in the best angle and direction.

At this time, the huge American fleet didn't seem to notice it at all, and stepped into the ambush circle of the Orca step by step in strict accordance with the standard plan! (To be continued.) )
