The xxi-2 submarine sounds like a modification of the xxi submarine, which seems reasonable. After all, the current xxi submarine is still a secret to the outside world. The only 2,000-ton submarine has subverted many people's understanding.

However, this model is just used to cover up the situation, just look at it a little bit. The so-called modified submarine has an underwater displacement of more than 6,000 tons.

This data alone is enough to stand out in the entire era. Once this submarine appears, it will rewrite the entire history of submarine warfare.

Almost all submarines need to be surfaced for ventilation, but this kind of submarine does not need it.

From the appearance, it is almost a synchronously enlarged xxi submarine. After all, the latter is also the main submarine built by Germany. It lengthens the water drop shape and has an underwater speed that exceeds the water speed. It is the correct submarine's appearance plan.

But the internal and ordinary submarines are a world of difference. They also have batteries, but the battery capacity is less than one-fifth of that of the xxi submarine, and it is only used to provide emergency power.

The rear of it, where the diesel engine was originally placed, has been replaced by a steam turbine, and is connected to the propeller at the rear through a reduction gear.

And in front, there is an atomic boiler, which can provide almost unlimited endurance with a terrible power of nuclear reactors.

In fact, even during World War II in history, Germany had already begun to develop nuclear reactors. At that time, it was just because it felt that nuclear bombs could not be successfully created, so it had to change its thinking and find something to do.

In this time and space, Germany's technology has made great progress. Driven by Cialek, a nuclear reactor test reactor has been in Syria, which has been operating safely for seven or eight years. In order to develop nuclear submarines, they have also built a special land simulation reactor. So far, the first generation of pressurized water reactors have been mature.

In order to ensure safety to the greatest extent, the pressure inside the nuclear reactor is not high and the power is not high, so that the submarine can only travel at a maximum speed of 15 knots, but it still has cross-generational significance.

It doesn't need to surface throughout the mission, it will be a ghost underwater that can appear anywhere!

Nuclear submarines are a system project, not just installing nuclear reactors on conventional submarines. The entire layout has been changed. There are also new systems, such as electrolyzing seawater to make oxygen and desalinating seawater through electricity. These are new requirements.

For ordinary submarines, fresh water is carried before departure, and oxygen is obtained by ventilation when floating. However, nuclear submarines need to be underwater for a long time, and everything has to be solved by themselves, relying on sufficient electricity.

In addition to these, Cialek also proposed some new ideas, such as laying sound silence tiles outside and using seven-blade large side inclined propellers. These proposals are very valuable and technicians are studying them. These new technologies have made the nuclear submarine still under test even though it has been launched for one or two years.

For example, a few months ago, the nuclear submarine was sent to the dock for a major change, cutting off the original three-blade propeller, replacing it with a new seven-blade propeller, and changing the gear ratio of the reducer. Through experiments, it was found that the underwater noise was indeed greatly reduced.

It can be said that current technology cannot discover this terrible nuclear submarine, an absolute deep cave in the ocean.

According to scientific principles, this nuclear submarine must undergo sufficient sea trials and be fully improved before it can be built in batches.

And now, the German Navy is eager to need such a big guy.

"It is expected that there will be several months from the time we cut off the American fleet in the Atlantic to when they choose the Pacific route. This time, it will be enough for our submarines to be deployed." Cialick said: "This time, it is time for our submarines to carry out brilliant combat."

"Yes." Hearing Dunitz's eyes, it was finally time for the submarine troops to step onto the main battlefield, let them go to the Bering Sea to show their skills! Especially, at that time, the nuclear submarine had completed the sea test and could conduct actual combat inspections.

After discussing the matter of the Navy, Cialick continued to put his eyes on the map.

Both the Northern and Central Lines have made great progress, while on the Southern Line and on the vast plains of Ukraine, German tank troops are galloping across the country.

After the battle in the Dubno-Lutsk-Rovno area ended, the German tank cluster was advancing towards Kiev, the capital of Ukraine.

Almost like history, Cialek is waiting for a large-scale siege in Kiev, which will continue to hit the confidence of the Soviets. Manstein is responsible for the South Road, and Cialek has no worries.

Cialek believed that news of the victory of the Kiev siege would arrive soon.

"The Romanian army has also completed the transfer recently. They plan to send troops to attack Aosad soon." Keitel said to Cialique.

Odessa, a city in southern Ukraine, the capital of Odessa Prefecture.

It is located 30 kilometers northeast of the Haikou where the Transnistrian River flows into the Black Sea. It is the largest port city and an important industrial, science, transportation, culture, education and tourism center along the Black Sea coast.

For now, it is an important port in southern Ukraine and one of the bases of the Black Sea Fleet. If Aosad is obtained, it will block the Soviet Union's passage of reinforcements from maritime transportation.

Although Germany has strong military strength, the area it spreads is too wide. Now it is better for the Romanian Legion to attack Aosade for Germany.

"We can't free up too much power now, we can only send about a regiment to assist the Romanian army in the attack." Keitel said: "The combat effectiveness of the Romanian army is definitely not comparable to our imperial army. It seems that the battle to attack Aosad may last for a period of time, or even more than a month."

"Yes, our ground forces are very nervous now. We cannot make any moves for the time being before encircling and annihilation of the defenders of Kiev and Uman, but we can dispatch the navy to enter the Black Sea and reinforce the ground forces."

The Black Sea is almost the inland sea of ​​the Soviet Union. Only through the Turkish Strait can one enter the Mediterranean. Now, the entire Mediterranean is controlled by Germany, and the passage of the Soviet Navy to go out is controlled tightly.

In this case, it is also impossible for the German Navy to enter the Black Sea and use the navy's firepower to reinforce ground combat.

"In order to avoid being attacked by the Soviet Navy aviation, I recommend continuing to use the Goethe-class aircraft carrier, which has three aircraft carriers and sixty carrier-based aircraft, which is enough to complete these tasks," said Raidel.

The precious Earl Zeppelin-class aircraft carrier should be fought on the ocean, and Redell does not want to suffer losses in the Black Sea.

Cialek nodded and was about to continue talking when he saw Goebbels walking in with a strange expression on his face.
