"I heard you came up with a complete set of new submarine combat plans in the prisoner-of-war camp?"

"Who said? We don't have submarines anymore!" Faced with Contini's inquiry, Denitz's first reaction was not to be happy, but to ask vigilantly. According to the Versailles Contract, Germany does not allow submarines to be retained, let alone explore new submarine tactics, so he was a little nervous.

"Of course I have my own information and intelligence channels. Mr. Dunkitz, to be honest, I know how to appreciate your tactics better than you old-fashioned senior executives." Contini smiled. "This tactic is vividly called the wolf pack tactics: during the operation, a few submarines were sent to hunt and regional patrol at sea in the predetermined waters. When the target was discovered, it was not in a hurry to launch an attack, but tracking, and constantly telling the target fleet to the headquarters. The headquarters assigned a wolf submarine to command the wolf pack to operate uniformly according to the distribution of submarines in the area... Attacks are usually initiated at night. Submarines in the wolf pack pass through the gaps or flanks of the opponent's frigate in secret, and use multiple submarines to launch attacks on the same target at the same time. This will increase the hit rate and achieve greater combat effectiveness than fighting alone..."

Denitz's face suddenly became cold: this was the core idea of ​​his tactics. He thought his thoughts really leaked the news, but he didn't know that the president on the other side was tying him!

"There are three key points in this tactic: First, there is a sufficient number of submarines, without scale, and even if you see prey, you cannot start; Second, you need a complete communication, command and support system. What determines the success or failure of a combat does not depend on each submarine, but on the command of the headquarters and the coordination of the on-site head wolf; Third, the submarine force must be capable of being well-trained - officers and soldiers must be able to endure loneliness, ships must have the ability to stay in the sea for a long time, and have strong enough attack capabilities." Contini smiled, "But I think there are still some flaws in this tactic or your idea, such as..."

He held his mouth at the right time.

"You said?" Dunitz asked anxiously. He is not the terrifying marshal and the doomsday leader. He is just a small torpedo boat captain - the future marshal. The king of submarines now does not have a submarine in his hand!

"I discussed it with General Sickett and decided to move your research institutions, personnel and related equipment and facilities in the Netherlands that are located in the Netherlands to secretly develop submarines to Italy - come to my United Shipyard, and I also acquired the Volken Shipyard. You must know what can be built there!"

At this time, Denitz suddenly realized: It turned out that the news leaked from Sickett, no wonder he was an army general and had a weak sense of confidentiality in the navy - how could he know that Sickett was just a scapegoat who took the blame?

"Your Excellency, you just said..."

"Where did I just talk about it? Oh, I mentioned the flaws." Contini smiled. This was his intentional act of sucking his appetite. "First, you have ignored the power of the plane - in the narrow Mediterranean, it may be reliable to simply use submarines. On the vast Atlantic Ocean, there are big problems with submarines that rely on pre-ambusting alone - there are fewer ambushings, too large surveillance range, and it is easy to be slipped away by ships. Too much ambushing will restrain too many troops, and the aircraft should be combined with the plane."

"If you want to fly..." Dunitz suddenly realized that the person in front of him was the young Italian air force theory authority? He must have a set of statements.

"At present, aircraft have very short air stagnation capabilities and are not outstanding in flight capabilities, but you have to face up to the development potential of the aircraft - this is much faster than the potential for submarines to develop. Currently, the speed of mainstream cargo ships is about 10 knots, so 12-14 knots is enough for submarines. In the future, mainstream cargo ships will speed up to 11-12 knots, and 14-15 knots are enough for submarines, but in the future, there will be aircraft with a cruise speed of 150 knots and a 6-8-hour space time. You can calculate how many sea surfaces can such a powerful aircraft monitor?"

Dunitz nodded. He didn't ask what the question is about where the plane took off - what is the sea floating airport used for?

"Secondly, you tend to develop multiple offshore and small submarines in the early stage. You think that the army is fast. My ideas are a bit different from yours. I tend to develop ocean-going, medium- and large submarines. You must be clear that what determines the victory of the submarine does not depend on the number of submarines, but on the number of torpedoes!"

"But you, the construction cycle of large and medium-sized submarines is long, which is higher than that of small submarines in terms of unit cost."

"There is a crucial problem of detention that should not be ignored. Although small submarines are cheap, their detention time is also short. They can only stay in the war zone for 15-20 days, or even shorter. Large submarines can fully undertake 40-50 days patrol missions. You might as well do an accurate calculation. To maintain the density and scale of long-distance sea areas, how many small submarines do you need to maintain, and how much does it take to replace them with large submarines?"

Dunitz nodded thoughtfully.

Shaoqing, Contini took Denitz into the chart room, turned on the light, and a huge model of the Atlantic Ocean sand table appeared in front of the two. Denitz took a breath of air conditioning - this was clearly a product that only the Navy Staff Department had. How could this kind of thing be in a company like United Group?

"My father is a naval colonel, so I have loved the ocean and the navy since I was a child, so I have this ship, this sand table, and this uniform." Then Denitz understood why the President had the rank of colonel of the Army, Navy and Air Force reserve, and it seemed that he was well-deserved.

Contini used a teaching stick to spot the British Isles: "The third flaw is that you tend to intercept merchant ships in the waters near Great Britain, because no matter what route the merchant ships take, they must go to the port. Close interception will help to wait and see, but I think this is impossible. There are two reasons: the first point is aircraft, and the aircraft poses a fatal threat to the submarine, so the range 300 or even 500 kilometers from the coast should not be easily accessible to submarines; secondly, the enemy will send escort troops with destroyers, frigates, and submarine hunting as the core, which is also a huge threat to the submarine. I think the most ideal interception point is here."

Dunitz looked over the instruction stick and found that Contini drew a huge arc circle around Azore - an arc circle about 1,000-1,200 kilometers away from Azore.

"There are few British aircraft here, and the seas are wide enough that the escort fleet will be severely weakened."

"But Azore?"

"This point is in the hands of Portugal... Do you think if we need it, can we build it as a headquarters for the North Atlantic submarine command of the front enemy? This is more reliable than being located in Berlin or Rome?"

"Boom", Dunitz felt that he was not in his mind, and he stuttered: "Portugal is a traditional British ally, and it is almost impossible to capture Azores from the Royal Navy!"

"Mr. Denitz, everything is done by man!" Contini smiled sly, "I can bet with you that if the Italian and German navy join forces in the future, there will be a way to take this place!"

"Did I come to the wrong place? This is not the Joint Group, this is the Joint Operations Command?"

"What I told you about is the future - at that time I wouldn't be just the president of the United Group, nor would you be just the captain of the torpedo boat, right?"

"Thank you for your encouragement!"

After discussing tactical ideas with Denitz in a wild and field-wide manner and gaining recognition from the other party, Contini talked about down-to-earth work: what submarines will be built next and how to use existing submarines for training.

Regarding submarines, the United Group now has a strong power. The Italian naval submarine design has three sources, namely the civilian plan designed by Ansaldo Company, the Otto Shipyard and the Adriatic Joint Shipyard (Grand United Shipyard) themselves; the Cavallini design plan and the Bernatis design plan, the latter two were led by the Italian Naval Engineering Department, and Cavallini and Bernatis themselves are Italian naval officers.

These three plans achieved the first results in 1925: Ansaldo's plan brought the Balila class submarine; Cavalrini's design became the Mameli class medium submarine; and Bernatis's design became the Fiela Mosca class and Pisani class.

At present, Ansaldo and United Shipyard are strategic partners of United Shipyard, so these plans are completely open to United Ship Group, and it is even a matter of one sentence to acquire and merger. The other two submarine plans are not difficult to get from the Navy Department. I heard that the president was going to mess with the submarines, and the Navy Department was so happy. Finally, there was a sucker who was willing to pay for us to play submarines. I had already presented the drawings and waited for United Ship Group to build them. As for whom the cause was later, the Navy didn't care at all. I still hoped that United Ship Group would take over the Dante at the end of the year. How dare I make the president unhappy now?

The Balila-class submarine is the first-class large ocean submarine of the Italian Navy, used to perform ocean-going missions, and adopts a full double-shell design: the surface displacement is 1,405 tons, and the underwater displacement is as high as 1,904 tons. The boat is 86.75 meters long, 7.8 meters wide, and the draft is 4.78 meters. It is equipped with two 4,000 horsepower diesel engines and two 2,000 horsepower motors, with a maximum surface speed of 17.5 knots and a maximum underwater speed of 8.9 knots. The maximum surface endurance is 7,050 nautical miles/8.5 knots, and an underwater endurance of 110 nautical miles/3 knots. It is equipped with 6 533mm torpedo tubes, a 120mm27-caliber deck cannon and 4 13.mm anti-aircraft machine guns.

After the intervention of United Group, the Balila-class that was about to be put into production was modified: Contini was very dissatisfied with the diesel engine of Franko Tosi used above. He believed that the excessive volume caused the submarine to be discharged at a high level and shortened the range. He asked to use the United Power diesel engine - a technology transplanted from Man Company, with a power of 3,750 horsepower, but the volume and weight were reduced by 11%, and the unit power and fuel consumption were reduced by 7%.
