Transmigrated as the Crown Prince

Seeing so many German ships, Captain Brian of the Little Shark-class submarine immediately issued a battle order.

The "Baby Shark" class submarine is a conventionally powered submarine built by the United States during World War II. It was also the main submarine of the U.S. Navy during World War II.

The external configuration of this class of submarines is still quite traditional, basically maintaining the appearance of World War I submarines. The boat is 95 meters long, 3 meters wide, has a draft of 2 meters, a surface displacement of 1,525 tons, a submersible displacement of 2,424 tons, and a submersible speed of 9 knots. Using diesel/electric propulsion, the surface endurance is 9,500 nautical miles (10 knots) and the underwater endurance is 500 nautical miles (3 knots).

Compared with submarines from various countries at that time, the "Baby Shark" class submarines in the United States did not have good endurance and maneuverability after diving. If they sailed underwater at high speed, the battery would quickly run out of power. Therefore, the "Baby Shark" class submarine spends most of its time sailing on the surface, and its speed on the surface is obviously much faster than underwater.

But even so, the "Little Shark" class submarine performed very well in World War II, often achieving major results, and it specialized in "eating" big guys, and its appetite was not ordinary. For example, in the Battle of the Philippines, they sank the Japanese aircraft carrier Shokaku and Gale. Such a record was even more brilliant than that of American aircraft carriers. In the Battle of Leyte Gulf, it was the "Baby Shark" class submarine that sank the Japanese cruisers "Atago" and "Maya".

After issuing the combat order, Captain Brian smacked his lips with regret. "It's a pity that there is no one else around." If multiple submarines were assembled to launch an attack like the German submarine force did, they might be able to achieve greater results.

In fact, the U.S. Navy in the original time and space also realized that single-boat hunting tactics were difficult to work, and launched some attempts similar to the "wolf pack" tactics of German submarines. The U.S. Naval Intelligence Department once discovered a Japanese convoy in the waters north of Rabaul. The commander of the Pacific Submarine Force ordered a group of three double-boat formations to be dispatched to intercept it to test the feasibility of submarine swarm operations. sex. However, the test was unsuccessful, and the group of boats sank only four Japanese ships. Although this is due to the fact that the Japanese Navy has improved its anti-submarine capabilities, it is mainly due to the immaturity and lack of experience in tactical cooperation among American submarines. At that time, the boats did not formulate specific attack tactics, and there was even no communication between them.

Just when Captain Brian was about to sneak up on the German fleet and launch a beautiful sneak attack, he did not know that the sea search radar on the destroyer responsible for escorting the German fleet also discovered it. "Found a submarine, 10 o'clock direction, 15 kilometers away."

Soon, Captain Brian saw a destroyer approaching them menacingly at high speed, and immediately put away his periscope. "Emergency dive, set a depth of 100 meters, and maintain a speed of four knots."

At this time, the ballast water tank was filled with water. After receiving the order, the speed of the tail propeller accelerated, stirring up water splashes, the hull of the boat tilted, and began to dive; while the sailors who were not on duty also ran towards the forward torpedoes. cabin (press the submarine's head to increase the trim angle, which can accelerate the dive)

Captain Brian cursed in frustration. "Damn it, it must be the German sea search radar!" Isn't the German radar performance too powerful? They just exposed a periscope. Can it be detected from such a long distance? ! Simply incredible! !

A few minutes later, the German destroyer arrived in this area and turned on active sonar.

Ping! Ping! Ping!

The cavity effect amplified the sound waves hitting the submarine shell, and Captain Brian's face instantly became extremely ugly.

"Shet!!" The United States has also developed active sonar, and he also has some knowledge of active sonar.

There are only two options now, either to surface and surrender to the Germans, or to fight Zhou Xuan underwater, looking for opportunities to counterattack or slip away.

Just as Captain Brian hesitated, the sonar man shouted softly. "Depth charges!"

Captain Brian didn't want to surrender so easily, so he gave instructions. "Continue to dive to a depth of 150 meters." Following his order, the propeller at the tail of the submarine slowly rotated, the hull of the submarine slowly tilted, and the front end moved toward deeper seas.

After diving to a depth of 150 meters, the active sonar sound waves hitting the submarine shell did not disappear. After a while, the sonar operator reported again. "Captain, the depth charge is over 100 meters and it's still sinking!"

"!!"what happened? Could it be a dud? Or did the destroyers on the surface predict that they would dive and simply set the depth to more than 100 meters?

"Continue to dive to a depth of two hundred meters." His intuition told him that it would be dangerous to continue to stay at this depth.

"Two hundred meters?!" The people around were shocked, but the helmsman still operated the steering surface and tilted the boat down. In the submarine force, the captain has absolute authority. If anyone disobeys orders during battle, the captain can even shoot him.

Soon, they reached a depth of 200 meters. The sonar operator held the earphone tightly and listened to the sounds inside. "The depth charge is still sinking, more than 150 meters!"

"Damn it! Full right rudder, full speed, full advance!" Regardless of whether the two depth bombs were dumb bombs, Brian did not dare to take risks. The depth here is already 200 meters, and the pressure of the seawater has reached a terrifying 20 atmospheres. Even the slightest damage to the submarine can cause the tragedy of destroying the boat and killing people.

But before it had sailed far, the depth charges had already fallen and exploded behind the submarine. With the explosion point as the center, the seawater rolled out countless waves, carrying a thunderous momentum, pressing towards the Little Shark-class submarine not far away. The hull of the submarine failed to withstand this terrible impact. The hull began to twist and deform, and with bursts of heart-wrenching noises, a large hole opened.

The turbulent seawater poured into the submarine along the broken opening. Before the sailors could react, the seawater flooded the rear torpedo room, and then went straight to the main engine control room, rear engine room, and forward engine room.

Captain Brian was keenly aware that the submarine was slowly tilting, and the bow of the boat was slowly rising involuntarily; he immediately ordered the tail ballast water tank to be drained. Unfortunately, the seawater has completely occupied the second half of the cabin of the submarine, and the hull continues to rise. Soon, the angle exceeds 30 degrees; what is even more frightening is that the entire submarine is sinking uncontrollably, and the depth has exceeded 210 Meters, 230 meters, 250 meters...

Bang bang!

The light bulbs above the head exploded one after another, and the interior of the submarine was pitch black. The entire submarine turned into a cold steel coffin, and slowly sank deeper into the sea amid the desperate screams of the crew.

For the German fleet, this was just an insignificant episode. The fleet only had one day's voyage left from Argentina.
