In World War II in history, the Americans took the lead in creating Bazooka, which is considered to be one of the four key equipment to win World War II, but the Americans are very strange and refuse to increase Bazooka's firepower.

The caliber of Bazooka is 60 mm, and it has not been expanded, compared to the German iron fist, the caliber is getting bigger and bigger, and it is directly super-caliber.

The bazooka is loaded from behind, so how thick the tube is, the caliber of the rocket will be larger, and it is impossible to be thicker, while the German bazooka is loaded from the front, so that the caliber can exceed the tube, that is, it is super caliber.

The later tank nightmare is enough to penetrate more than 200 mm, even if it is blocked by the grille armor, it can burn through the enemy's tank armor.

In terms of rockets, Germany is indeed also brushing calibers.

Now, the battle against Moscow has gradually advanced, and the biggest battle in the European theater has slowly begun.

At sea, the battle is also going on.

Pick the island.

The cool breeze of the Pacific Ocean blows through the weeds and jungles of the sea, and this is just a small island in the middle of nowhere, with the occasional fisherman coming up. But recently, there are no more fishermen, and the fishermen have been ordered by the government not to go to the island again.

If you look at it from a distance, you can see black smoke coming out of this island, it is a newly built thermal power station, the power is not very large, the smoke coming out, in many cases is similar to cooking smoke, and the chimney also stands in the middle of the trees, which is inconspicuous.

Then, there were all sorts of loud explosions, roars, coming from the island, and it was clear that earthworks were going on there.

And recently, that sound has finally died down, because it's finished.

From the outside, there is no difference, just in the eastern part of the island, there is a natural channel, and the sea water flows down this channel until it reaches the inside of the island, and then enters the cave.

Inside the cave, there are electric lights hung up, which illuminates the cave very brightly, this is a natural cave, half seawater, half flat ground.

The area inside the cave is quite large, and on the flat ground, at this time there are already various mechanical equipment, some of which can be used to hoist torpedoes, some are used to overhaul equipment, and in a short period of time, a submarine cave has begun to take shape.

At this time, there was a rumbling sound in the waterway outside, the propeller driven by the electric motor was turning, and a large submarine slowly drove in, and only after the top was covered did it float up from under the water.

That huge body looks quite domineering.

"Crunch." The hatch at the top opened, and a sailor came out first, who came down from it with great excitement and shouted inside: "Come back, we are finally home!" ”

From now on, this will be their home.

There was a smell wafting in the distance, and they couldn't help it when they had eaten the compressed food inside the submarine for a month, and now they smelled this fresh delicacy.

A sailor came down from above, and the fifth, who looked older, looked at it all with his eyes blazing, his clothes still straight, and the rank of captain on his shoulders.

The rank of submariners is generally not high, generally speaking, a lieutenant or captain is already a captain, and very few can survive to a major.

This must be the captain.

"Wellenbrook, you're finally here." At this time, a person on the ground next to him greeted him, and this person's shoulder, also a captain.

"Moher, why are you so fast?" Willenbrook asked.

They were both submarine captains, had studied at the same submarine school, and then joined the combat unit together, and now with the continuous expansion of German submarines, both were captains.

"I encountered a suitable current." Moher said, "I came here yesterday, and I have already completed all the supplies, and when you come in, I will set off." ”

After coming from the base, crossing the Mediterranean Sea all the way, taking the Suez Canal, and circumnavigating most of the world, I finally came to the new submarine base set up by Germany on the island of Zeta, and it took a day to complete the replenishment, and now, after waiting for the waterway to get out of the way, I can set sail.

The cave is large enough to accommodate five or six submarines at the same time, but the passage in and out is not wide, and after the explosion and expansion of the sappers, it can only accommodate one submarine, so they must enter and exit in order.

"I envy you." Willenbrook said, "I want to go out immediately to find the Soviets' transports." ”

"Don't worry, there are many opportunities, once there is a situation, we will immediately send a telegram to inform you, this time our tactic is to cooperate with multiple submarines to fight, and now, several submarines have gone out."

After a few words of exchange, Mohel stepped into his submarine, and when he closed the hatch on the top, U-124 slowly sailed out of the cave.

There are a lot of supplies in the supply base here, and at this time, the entire submarine is stuffed, and the aisles are stacked with cans and fresh water.

The diesel engine made a rumbling sound, starting from the U-100, and the next new submarine of the new board number, have been equipped with AIP auxiliary cabins, because of the consumption of helium in the gas tank, so it will only be used in combat, in peacetime, it is the best choice to use the diesel engine directly.

In order to avoid exposing the base here, they were in a snorkel state, sailed out of the submarine cavern, sailed into the sea, and continued to drive forward for hundreds of nautical miles, so that the submarine base was not exposed.

However, they still did not sail.

In the past, submarines spent most of their time on the water, and they would dive when they encountered a situation, but German submarines were already mainly underwater sailing, and after going to sea, almost all of them were underwater.

No one will know that Germany has sent its submarine forces to the northern waters of the Pacific Ocean, and now there are more than a dozen submarines arriving here, and the follow-up is still coming, and the final deployment of submarines here will exceed hundreds, and they have only one goal, that is, to intercept all the merchant ships, so that the Soviets do not get half of the American supplies!

Tigers are afraid of wolves, and the bloodthirsty wolves make all the behemoths of nature shudder. Under their siege in turn, even the king of beasts could not be spared.

Forming small detachments of several submarines and launching underwater attacks on enemy warships and transport ships like wolves was the tactic that the German Navy was about to implement.

"Captain, a notification was received from U-107 that the transport fleet was spotted."
