Since United Group paid for the money, many other things had to be changed according to the president's requirements: for example, the 13.2mm anti-aircraft machine guns turned into 12.7mm joint machine guns, and the radio stations on them also became United Telecom products. In 1926, United Radio Company entered the field of wired telephones in addition to traditional radios and radios, so United Radio became independent from United Electric and became two subsidiaries, United Radio and United Communications. Collectively, United Telecom. Betty naturally became the head of this section and was the only woman among United Group executives. However, she is now married and has become much more mature, and no one has any remarks about this matter.

Originally, the development of Italian telecommunications could be carried out step by step. In this era, only government positions and wealthy people could use telephones. However, under the strong promotion of Contini, this demand was completely released - he promoted telephones in government agencies and schools like he last promoted radios. In addition, the newly built residences of the United Group - both the Leader's New Village and the high-end residential areas have installed telephones, and basically one unit per unit.

As a result, the number of telephones in cities such as Milan, Rome, Genoa has increased rapidly, from just a few hundred doors to thousands, and equipment updates are urgently needed. Therefore, the carrier telephone technology that appeared in 1918 (4-channel telephones are opened on a pair of copper wires), and the vertical and horizontal telephone switches (invented in Sweden) that appeared in 1923 were all introduced to Italy to take root. With the efforts of German and Italian engineers, "independent innovation" products will soon appear.

Whether there is a telephone in the apartment is the first sign that distinguishes United Real Estate's products from other residential buildings. The second sign is whether they are used with grand and shiny aluminum alloy doors and windows. The third sign is whether there are professional security and service personnel in the community. These value-added contents make United Real Estate's residential prices higher than other residential buildings and still favored by the middle class. It is said that United Real Estate will soon launch a fourth significant difference: preparing to build 10-12-story high-rise buildings and equipped with elevators.

It is precisely because of the investment and innovation of these work that United Real Estate has had a very good situation this year. Not only has its profits rise sharply, but it has also enhanced United Finance's market influence - most of the housing mortgage loans for these residential buildings were released through United Banks, which have improved the progress of various industries including glass, water pipes, paint, cables, etc. When the Joint Steel is put into production at the end of the year, the large-scale rebar and other construction steel used can be produced and sold by themselves, and has been praised by the president many times. It is said that it is expected to be rated as a Class A enterprise by the end of the year.

The German mercenary officers, including Denitz and others, have also settled in places like the Leader's New Village, which is nothing more secure. Their only feeling is that Italians will enjoy it - but living in it is quite comfortable.

However, Denitz is not in the mood to think about whether he lives well. He is attracted by this drawing. After careful examination, he asked: "Are you going to build a large number of such submarines?"

"It is impossible to build in large quantities, because the price is not expensive and the first construction is more than $3 million. Even if it is built in bulk, it is difficult to reduce the amount of $2 million. Unless we find more economical raw materials and equipment to manufacture, it is impossible to copy in batches - 5 such submarines are equivalent to one Caraciolo class. How many of those traditional naval generals do you think are willing to spend so much money on submarines?"

This made Denitz feel sad: Not only Italy, but Germany is almost the same. The surface fleet sent generals to develop their main warships regardless of their utmost, without even looking at the submarine.

"But don't worry, we have placed 4 orders, the first batch of two ships started to be built in October last year, and the other two ships will start to be built in the second half of next year - United Group is responsible for spending half of the money, so I have a lot of say. You have a lot of time to verify the use. I have two positionings for this submarine: First, he is the regional leader, acting as a command submarine; second, he is a supply supplement, acting as a cow submarine."

"dairy cow?"

"This batch will have a modification in the future, which will increase fuel, food, and torpedo carrying capacity to provide supplies to other small and medium-sized submarines, and will not perform combat missions themselves - only retain a very weak self-defense ability." Contini smiled, "I know that the German Navy usually uses merchant ships to disguise as supply ships, but in this process, it is full of risks and is easily discovered by the enemy, especially those that may hit enemy countries or even neutral countries at any time. If submarines provide supplies, it will not only be more hidden but also more flexible and convenient - in emergencies, submarine officers and soldiers can also achieve partial rotation!"

Dunitz said excitedly: "This is a genius idea. I will carefully consider how to use it in the new tactics, which means that our tactics will have more room for maneuver!"

"I personally think that the medium-sized submarine solution designed by Mr. Bernatis may be more suitable for large-scale batch construction. Of course, his current design is a bit too large, because of the power of the diesel engine..."

The surface displacement of this submarine is 1,060 tons, and the underwater displacement is about 1,250 tons. It is equipped with 2 100mm 47-caliber deck guns, 8 21-inch (533mm) torpedo launch tubes (bow 4, stern 4) and 4 13.2mm anti-aircraft machine guns. The torpedo carrying capacity is 12 (can be increased to 16 if necessary), and there are 300 shells and 3,000 machine gun bullets.

After Contini's intervention, he made more drastic modifications. The water surface displacement was cut from 1060 to 870 tons, the underwater displacement was 1040 tons, and two deck guns were cut off. The machine gun was replaced simultaneously as usual, and the ammunition carried was also reduced accordingly. When making these adjustments, Contini benchmarked the most famous Vii-class submarine in Germany, which was built the largest number of Vii-class submarines, but the Vii-class submarine had only 769 tons of water displacement. Relatively speaking, after adding these 100 tons of water displacement, the crew's cabin and maintenance system could be better used - Contini believes that this will help further enhance combat capabilities.

The power still uses the combination of 2 diesel engines + 2 electric motors. The single output power is nearly 1,500 horsepower. The battery pack is divided into 132 units and two four-blade propellers are propelled.

The design of this submarine is still being further improved, mainly to combine the opinions of the two naval experts. At present, the Italian Navy generally believes that the hull part of Cavallini's design plan is better. He has a saddle-shaped water tank and a cylindrical pressure-resistant boat hull with excellent performance. The hull is supported by a large number of cylindrical steel beams (reinforcement rings). Each steel beam is spaced about 500mm, and the steel plates are riveted on the steel beam (each steel plate overlaps with the adjacent steel plate). The hull is made of nickel steel, with the hull being 18mm thick, and the two ends are 16mm thick. It can withstand a maximum pressure of 60 kg/square mm. The outer hull is made of 7mm thick steel plates. Fuel and ballast water are stored between the inner and outer hulls. The entire hull is divided into 5 main parts and the control room.

Starting from the stern of the boat, the first compartment is the torpedo compartment of the stern (including the motor), followed by the engine compartment, the control room, the officer and the non-commissioned officer living area and the first battery compartment, and finally the bow torpedo compartment and the second battery compartment. Above the control room is the command tower, each watertight compartment can withstand 40 atmospheric water pressure. The reinforced watertight compartment can provide better safety, with a maximum designed dive depth of 140 meters.

After Contini's intervention, another requirement was added to the design: the main components of this submarine should be transported through railways.

"Railway? What does this mean?"

"The first is the need for combat, and the second is the need for production." Contini smiled. "There is no direct waterway between Germany and Italy. If you want to achieve cross-border dispatch of submarines, you must detour the far North Sea and the Mediterranean. I think it is uneconomical - it is better to transport submarine components and personnel through railways. It only takes 20 hours to get from Berlin to Rome. I think it will take less than 10 days to assemble a submarine with complete components - this is more convenient and safe than cross-sea dispatching; as for the second, it is the specific application of your wolf pack tactics in production!"

"The production and application of wolf pack tactics?" Dunitz was a little puzzled, "You mean?"

"It's very simple. If all the main components can be transported by railway, it means that as long as the final assembly process is at the beach, other production processes can be placed inland or even underground! After all, it is a minority for submarine manufacturing in harbors. If every industrial city can produce qualified submarine components, wouldn't it mean that there are docks and workshops everywhere in the country? It can not only speed up the production pace and improve efficiency - one is that a factory produces all components, and the other is that a factory is only responsible for producing 1-2

Components, which speed do you think is better? It is also beneficial for concealment and dispersion - in the past, to destroy submarine production, it was enough to destroy the docks and shipyards. Now it is not possible. It must destroy the production network covering the whole country, and at least destroy the key nodes. How easy is it?" Contini smiled, "So my attitude is very tough. Don't always tinker with multiple models to make things difficult for yourself. We should try every means to focus our advantages on one or two models, strengthen versatility, and simplify production requirements."

"Can the bureaucrats in the Admiralty listen to you?"

"They will listen." Contini made a gesture of counting money with his hands. "This submarine is now costing 1.5 million US dollars (1926 US dollars), and mass production can be reduced to 1.2-1.25 million US dollars. If I use my method to strengthen production, national or even cross-border cooperation, the cost may be reduced to 1 million US dollars. I told the bureaucrats of the Admiralty that if they want to build 200 ships in the future, I will pay half of the money! Isn't it just 100 million US dollars, I can afford it!"

"Oh my God, 200 ships!"

"Actually, I want to say 400 ships, but I'm really afraid of scaring them, so I shrank half of them first, and half of them see if I can make enough money." Contini smiled, "I suggest you design the wolf pack tactics based on the scale of 300 ships!"

"Of course it's OK, but CEO, why do you do this? Wouldn't it be better to keep $100 million for yourself?"

Contini smiled: "You definitely don't like to listen to lies. Telling the truth seems too rude. I will only say one thing: I just celebrated my 23rd birthday and entered my 24th year. Don't underestimate the ambition of a young man. He is now the president. Can you only be the president in your life?"
