Transmigrated as the Crown Prince

A few days later, the destroyer equipped with active sonar was finally officially commissioned amidst the "highly anticipated" operations. Navy executives couldn't wait to send it to the eastern coastline of the United States to destroy the damn German "ghost submarine."

When the destroyer arrived near New York, it received news that a cargo ship had been sunk and rushed over immediately. The sea area where the freighter was sunk was not very far away from them. The destroyer arrived at that sea area after sailing at full speed for more than ten minutes.

There was no movement in the passive sonar, and the captain ordered the active sonar to be turned on and depth charges to be ready.

The sound waves of active sonar began to spread on the seabed. The German submarine was not far away, so naturally it could not escape these sound waves. Sound waves hit the boat one after another. If it is an ordinary submarine, when it is hit by active sonar waves, the hull of the boat will vibrate. The cavity effect will amplify the sound. The submarine soldiers inside can clearly hear this. Terrible sound.

However, when the active sonar sound waves of the US destroyer hit the German submarine, the first thing it came into contact with was the anechoic tiles laid on the submarine's shell!

"Reducing the enemy's active sonar detection distance" is the main function of the anechoic tile. Its working mechanism is to generate impedance matching between seawater and the hull, so that sound waves can enter the anechoic tiles. Due to the damping effect of the anechoic tile materials and the role of the cavity or filler in the tiles, the sound wave waveform is transformed, and the sound energy is It is converted into heat energy and is consumed, thereby greatly reducing the returned sound wave energy, thereby achieving the purpose of reducing the active sonar detection distance.

The German Tiger Shark class is a double-hulled submarine with silencer tiles laid on both the inner and outer shells. The outer layer of silencing tiles is mainly used to deal with active sonar, while the inner layer of silencing tiles is mainly used to reduce noise.

Therefore, the sailors inside the submarine barely heard the sonar waves hitting the boat. Only the sonar operator quickly took off his earphones and cursed quietly. "Damn Americans! Captain, Americans' active sonar!"

The submarine captain raised his eyebrows slightly. "The Americans are also equipped with active sonar?" However, he did not panic and ordered calmly. "Maintain a speed of five knots and reduce noise." Because this submarine has already passed the sonar test of its own surface ships, active sonar can hardly detect it, and the noise of a speed of five knots will not be detected by passive sonar.

Sure enough, the US destroyer on the water circled around but found nothing. The captain became a little anxious. "Sonar crew, have you found anything?!"

The sonar man shook his head. "Captain, there's nothing down there. I'm afraid the German submarine has already left."

The captain thought for a while and then ordered. "Search eastward." The destroyer turned around and headed east, but just after sailing more than a thousand meters away, there was a huge explosion and everyone on the bridge was thrown to the ground.

"What's going on!" The captain, who finally got up, asked, when he realized that the whole ship was slowly tilting. "Oh God! Abandon ship! Abandon ship!!" With such an obvious tilt, it was obvious that it had been severely damaged, and there was no need for damage control. "Order everyone to abandon ship!" He said and rushed out of the bridge, and was shocked to see that most of the stern of the ship had been blown up.

The captain didn't care about anything else. He took the life jacket on the side and put it on, jumped into the sea, and swam out as hard as he could.

"What?!"

Word quickly reached President Wilkie's office. President Wilkie's face suddenly darkened when he heard that the destroyer they had high hopes for had been sunk in less than a day of service. "General Leahy, what the hell is going on?!" He kept saying that from now on, German submarines would be invisible to active sonar and would no longer be a threat; is this the result? Isn't this too embarrassing? !

"This..." General Leahy's old face turned red. He was extremely embarrassed and wanted to find a hole to burrow into immediately. Logically speaking, active sonar should be able to search for German submarines. How come they were sunk instead? "Perhaps there is something wrong with the active sonar?" After all, this is the first time something has been put into actual combat, and no one can be sure it will be foolproof.

As the saying goes, the greater the hope, the greater the disappointment. President Willkie was too depressed to continue discussing this issue. "What's going on over there in the Soviet Union? Have they wiped out the German troops who destroyed the railway?"

"Not yet, Mr. President." Seeing President Wilkie's face getting more and more ugly, the secretary quickly reported the good news. "Stalin agreed to send a fleet to defend the Aleutian Islands."

"Hmph. He knows what's going on." President Wilkie snorted coldly. But even if we can save the shipping lanes in the Pacific, what's the use if we can't save the railways? "Are those Germans so difficult to deal with? How many days have it been?"

In distant Moscow, Stalin also raised the same question. "Why haven't those Germans been eliminated?!" Because those damn Germans continued to harass the railways, there were only 5 trains arriving in Moscow in this week. "Order them to wipe out everything within three days!!"

In the mountains 20 kilometers away from the railway, Fred and his party ambushed another Soviet army that entered the mountains to search. The weapons of these Soviet troops were only Mosin Nagants and a few light machine guns. They were overwhelmed by the powerful firepower of the German army and were quickly wiped out.

He pulled out the ID from a corpse and checked its serial number. The deputy company commander curled his lips in disdain. "These guys are just like the last batch. They are rookies who have just been formed. Don't they have mountain troops in the Soviet army? Why don't they send those troops over?"

According to the establishment, the Soviet army has a total of 19 mountain divisions: 6 divisions of the Kiev Special Military District (44th, 58th, 60th, 72nd, 96th, and 192nd Mountain Divisions), 1 division of the North Caucasus Military District (28th Mountain Division), and 7 divisions of the Lower Caucasus Military District (9th, 20th, 47th, 63rd, 76th, 77th, 138th Mountain Division), 3 detachments of the Central Asian Military Region (68th, 83rd, 194th Mountain Division), 1 detachment of the Far Eastern Military Region (101st Mountain Division) and the 9th Independent Army ( 30th Mountain Division).

Fred on the side couldn't help rolling his eyes after hearing this. "These rookies are so easy to deal with."

The deputy company commander chuckled. "These newbies from the old school came here. I feel that Stalin didn't take us seriously." In the past few days, they have eliminated more than 1,000 Soviet troops who entered the mountains. In addition, countless people were killed and injured by the mines they planted. number. But the Soviets still entered the mountains one after another to search for them, and they sent new troops that had just been established. These guys have no combat experience at all except how to shoot.

As a result, seeing that the fighting situation here was so bad, the superiors planned to send another company of paratroopers to support them.

"We have to move somewhere again." They have moved their camp four times in the past few days and are already more than 100 kilometers away from where they just landed. It can be considered a long journey.

Back at the camp, they simply packed up their supplies and equipment and set off again.

After walking for a while, everyone suddenly saw a black-skinned wild boar climbing up a tree in front of them.

"Oh, this guy is really big. He must weigh 450 pounds, right?"

"Kill him, just for a change." Just as everyone was about to kill the wild boar for a change, the wild boar turned its head when it heard the noise, staring at everyone with its eyes. The hooves began to dig at the ground.

Seeing this, Fred was not polite. He raised his FAL rifle, pointed it at the wild boar, and shot it.

The wild boar staggered after receiving this shot, its ferocity was completely aroused, and it sprinted towards everyone. This wild boar was not slow when it exploded, and it rushed forward in a few steps.

Fred fired twice, hitting the wild boar in the head, and the wild boar fell to the ground.
