In World War II in history, the Americans took the lead in creating Bazuka, which is considered to be one of the four key equipment to win World War II. However, the Americans were very strange and refused to increase Bazuka's firepower.

The caliber of Bazukka is 60 mm, and it has not been expanded. In contrast, the caliber of German iron fist is getting bigger and bigger, and it is directly super-caliber.

Bazukka is loaded from the back, so the thicker the tube is, the larger the caliber of the rocket must be, and it is impossible to be thicker. The German rocket launcher is loaded from the front, so that the diameter can exceed the tube, which is super-caliber.

The later tank nightmare can reach a depth of more than 200 mm. Even if it is blocked by grille armor, it can burn through the enemy's tank armor.

In terms of rockets, Germany is indeed caliber.

Now, the battle against Moscow has gradually advanced, and the largest battle on the European battlefield has slowly begun.

At sea, the battle is also going on.

Choose the island.

The cool sea breeze in the Pacific Ocean blows through the weeds and jungles by the sea. This is just a deserted island, with fishermen occasionally coming up. But recently, there are no more fishermen, and they are all under martial law. The fishermen have received orders from the government to not go to this island again.

If you look from the sea from afar, you can see black smoke coming out of this island. It is a thermal power station just built. The power is not very large. The smoke coming out is often similar to the smoke from cooking, and the chimneys stand in the woods, which are not conspicuous.

Then, there were all kinds of huge explosions and roars coming from the island, and it was obvious that earthwork was being carried out there.

And recently, this sound has finally disappeared because the construction has been completed.

From the outside, as before, there is no difference. Just in the east of the island, there is a natural canal. The sea water flows along the canal and flows into the island, and then enters the cave.

Inside the cave, electric lights were hung, making the cave extremely bright. This is a natural cave, half of which is sea water and half of which is flat ground.

The area inside the cave is quite large, and on the flat ground, there are already various mechanical equipment, some of which can be used to hoist torpedoes and some to inspect and repair equipment. In a short period of time, a submarine cave reservoir has taken shape.

At this time, a rustling sound came from the waterway outside. The propeller driven by the motor was rotating. A large submarine slowly drove in. After the top was blocked, it floated up from underwater.

The huge body looks quite domineering.

"Cruff." The hatch door at the top opened, and a sailor first came out of it. He got down from above with great excitement and shouted inside: "I'm back, we're finally home!"

From now on, this will be their home.

A scent came from afar. After eating compressed food inside the submarine for a month, they could not help it when they smelled the fresh delicacy.

A sailor came down from above, the fifth man who came out looked older, his eyes were bright and his clothes were still straight, and his shoulders were carrying the rank of captain.

The rank of submarine soldiers is generally not high. Generally speaking, lieutenants or captains are already captains, and very few can survive until majors.

The captain must have come out.

"Willenbrook, you have finally arrived." At this time, a man on the ground next to him greeted him. The man's shoulder was also a captain.

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

They were both captains of submarines. They once studied in the same submarine school, and then joined the combat troops together. Now, with the continuous expansion of German submarines, both of them are captains.

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

Come from the base, cross the Mediterranean, walk the Suez Canal, and circle around most of the earth, and finally arrive at the new submarine base set up by Germany on the Zezha Island. It took a day to complete the supply. Now, you can only wait for the waterway to move out and then you can sail.

The cave warehouse is very large and can accommodate five or six submarines at the same time, but the waterways entering and exiting are not wide. After the engineers explode and expand, they can only accommodate a submarine, so they must enter and exit in order.

"I really envy you." said Willenbrook, "I really want to go out to find the Soviet transport ship immediately."

"Don't worry, there are many opportunities. Once there is a situation, we will send you a telegram to notify you immediately. This time our tactic is to cooperate with multiple submarines. Now, several submarines have already gone out."

After a few words of exchange, Moher stepped into his submarine. After he closed the hatch on the top, the submarine u-124 slowly drove out of the cave.

There is a lot of stuff needed to be supplied in the supply base here. At this time, the entire submarine was stuffed, and cans and fresh water were piled up in the aisles.

The diesel engine made a rumbling sound. Starting from u-100, the next new hull submarines have been equipped with AIP auxiliary cabins. Since helium in the gas storage tank is consumed, it will only be used during combat. In normal times, 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 and drove out of the submarine cave, drove into the sea, and continued to move forward for hundreds of nautical miles, which was not considered to be exposed.

However, they still did not fly.

In the past, submarines were mostly sailing on water and would dive when they encountered situations. However, German submarines were already the main underwater acts, and after going to sea, almost all of them were underwater.

No one would know that Germany had sent its submarine troops to the northern Pacific Ocean. There were more than a dozen submarines arriving here, and the subsequent ones were still coming. In the end, more than hundreds of submarines were deployed here. Their only target was to intercept all merchant ships and prevent the Soviets from getting any US supplies!

Tigers are afraid of wolves, and the bloodthirsty wolf pack makes all the behemoths in nature shudder. Under their repeated siege, even the king of beasts will not be able to survive.

Grouping a team of multiple submarines and launching underwater attacks on enemy warships and transport ships like wolves. This is the tactic that the German Navy is about to implement.

"The captain, received a notice from u-107 and discovered the transport fleet."
