Unlike the XXI submarine in another time and space, Germany directly evolved the bow part of the submarine to resemble the bow of the Chinese Type 033 conventional submarine in the 60s, instead of adopting the still sharp bow design of the XXI submarine. This also made the latest German submarine number jù for the first time appear on the surface speed is not as fast as the underwater speed, completely subverting the traditional submarine design concept of "a boat that can dive".

The same improvement in terms of reducing anti-aircraft gun armament, the number of Allied aircraft in the Atlantic Ocean is now not large, and in order to compromise the underwater quiet performance and underwater speed, this new submarine retains only a 40 mm caliber anti-aircraft gun with a limited firing range, which is also different from the XXI submarine in another time and space.

Another terrible change is still in the bow sonar system, because of Accardo's systematic weapons technology reserves as early as 1925, Germany has not taken a detour at all in many weapons design, and has also invested more manpower and material resources in the right direction for development and research, coupled with Germany's consistent leadership in science and technology, has created a large number of world-leading advanced electronic equipment, radar and sonar are part of it.

As a result, this new type of submarine, which has a relatively spacious interior, has been endowed with more and more advanced electronic equipment, and has become the true ancestor of a modern submarine. The sonar in the bow gives it the terrifying ability to launch torpedoes directly under water, and it is the first submarine in the world to launch torpedoes directly to attack surface targets without periscope-assisted aiming.

It is also equipped with a small, collapsible radar antenna that can search for enemy ships within 25 kilometers of the sea surface and alert aircraft within 75 kilometers of the sea. This achievement, combined with a maximum depth of 200 meters, makes this submarine the safest underwater killer that is technically almost impossible to sink today.

Of course, this is an integral part of the plan for the reorganization of the modern German navy, and in the future the German Navy will have three types of ships as the main force of the navy, one is an anti-submarine anti-aircraft missile destroyer and cruiser with escort as the main function, one is an aircraft carrier as the core of the fleet, and the other is an ocean-going submarine.

This direction of naval development, which has been proven correct, allowed the Germans to skip the gap between battleships that they had too late to catch up with in their own development, and directly pulled the world navy into the era of the air fleet with aircraft carriers as the core, and also made the originally weak German Navy leap into a world-class naval force, and then defeated the powerful Royal Navy of the British Empire.

Today's naval warfare has become unrecognizable, and the era of large naval ships and huge guns led by Britain has begun to gradually come to an end, and the era of the air fleet, pioneered by Germany, Japan, and the United States, which is a new naval power, has quietly unveiled itself and is unveiled in front of the naval commanders of various countries.

With radar and carrier-based aircraft as a means of reconnaissance, the navy has already possessed all-weather three-dimensional reconnaissance and discovery capabilities, and the powerful cannons in the previous naval battle mode can no longer threaten the modern aircraft carrier fleet because of the limitation of range, and the power of destroying the world has also become ineffective with the embarrassing situation of insufficient range, and Germany's attack on the British home fleet and the naval battle between the United States and Japan in the Pacific Ocean has proved that the aircraft carrier fleet is becoming more and more important in naval warfare, and the naval battle mode in which the aircraft carrier fleet fires in formation has begun to gradually decrease.

Of course, the madmen in the Tokyo base camp who clamored all day long to knock on the door of the West Coast of the United States with the main guns of battleships were obviously not included in the scope of the progress of the times. After all, the scene of sending the enemy to the bottom of the sea with naval artillery is really too lingering, so it is absolutely understandable for some people to hold the idea of the supremacy of naval artillery......

After all, not everyone is like Accardo, who can clearly see the direction of future weapons, and following the old experience of warfare is the best model that other world powers can choose. Every great power has its own experience and summary of the war, Germany lost World War I, prompting Germany to begin to reflect on its own experience, and the "Treaty of Versailles" lagged behind Germany's military science and technology for a period of time, which made Germany's scientific and technological development blind and inexperienced, so Accardo had the opportunity to intervene and change. As for the victorious powers, they are convinced of their experience and that they are in the right direction.

The entry of the Manchu Qing Dynasty provided them with corresponding war experience, and mounted archery was superior to firearms, and bravery was greater than science and technology, and they believed in it for two hundred years. So don't laugh at the fact that Japan still believed that battleships could defeat aircraft carriers in October 38, because they relied on artillery warships to rise, which has only been 30 years, and it is still a matter of course to learn from the previous experience of large ships and giant guns.

In addition to the fact that the combat mode of the Navy has changed, in fact the Luftwaffe has always been at the forefront of the world. Germany's original technology accumulation in aircraft engines was not advanced, and it was even a bit backward. Although Accardo made great efforts to make up for it in the era when he was in charge of the Wehrmacht's scientific research, he could only barely stay behind.

However, as the Luftwaffe gained an advantage on the front line and captured the engines of some aviation powers, in fact, Germany's technology accumulation has completely caught up with the world's first-class aero engine power, Britain, and it took half a year to thoroughly eat the British Rolls-Royce engine technology.

As a result, the German engines are more reliable, the output horsepower of the engines is also more powerful, and the Ta-152 fighter has flown a limit flight speed of 750 kilometers per hour in the real state, which has in fact surpassed the flight speed of Britain's latest secret weapon, the Meteor jet fighter, but the reliability is more than ten times stronger than its strongest opponent.

Who would have imagined that under the compulsion of the terrible performance superiority of the Luftwaffe, in less than two years (calculated from the beginning of the Spanish Civil War), the flight speed of the world's mainstream fighter jets has increased from about 300 kilometers per hour to the current general 550 kilometers in one breath?

During the German bombing of Britain, the Luftwaffe showed the world how easily the strategic air force could destroy a country's war potential under the protection of superior air supremacy, and the tactical air force that accompanied the German troops in the skies over the battlefield pointed out to everyone the essence of the battlefield support air force.

However, the real change of the plane is still in the real room of the Germans, and once this new type of aircraft appears in the sky, it is destined to be another earth-shaking change. At that time, mankind will enter a new era of aviation, both in speed and performance, will open a new chapter in history.

Of course, the change in the Army is even more exciting than the pursuit of faster, faster, faster Air Force equipment. At the same time as the commissioning ceremony of the Navy's first fuel cell submarine was being held, in the production workshop of the Krupp factory in Germany, the army's latest weapons and equipment, the first King Tiger tank, was carefully driven down the production line under the drive of skilled workers.

This is not just a tank was produced, a new type of tank began to enter service such a simple progress, the final production of the King Tiger tank was completed, marking the beginning of the army equipment to take its own steps in the field of scientific and technological strength, German equipment in the opponent in the armor thickness artillery power at this time, the first to achieve surpass, re-establish their own leadership in armored weapons.

Aside from the innovation and improvement of this King Tiger tank in armor and power system, it uses advanced equipment that is almost invisible on tanks in various countries, including the prototype of some advanced electronic equipment, which has proved that this tank is definitely a cross-era product in this time and space. The infrared night combat system and the shooting stability system can already see the shadow of the future main battle tank, and the German army's lead in armored vehicles is still unchallenged.

In addition to the new helicopter officially named the Nordic god "Odin", Germany's plan to create an air-ground integrated army combat mode is also steadily being implemented, and will eventually blossom in the near future and become a new combat mode for the army. This model will change the way the army fights in the future, and the German armored forces will introduce new rules of war before the opponent can adapt to it.

However, when it comes to the King Tiger tank, Germany's progress in another direction is more significant than the King Tiger tank itself. This is the famous helicopter manufacturer Frank Stoner, Krupp and the White Lanhua Group jointly launched the first mechanical control zhì automatic production line in human history, this production line allowed Germany to reduce the consumption of man-hours in the production of King Tiger tanks, improve the efficiency of workers, and finally achieve the production cost of King Tiger tanks to a lower level than Tiger tanks.

In the absence of computers, this kind of automated production workshop based on mechanical aspects, in fact, the automation process is not as high as imagined, but this can be said to be another leap forward in industrial civilization, which marks the beginning of Germany in the fast lane of industrial production capacity, the United States in this area of slight advantage is now being caught up by Germany, even surpassed.

Therefore, in Accardo's view, the real fatal improvement is the improvement of Germany's industrial base, the improvement of the energy environment of the Third Reich, and the success of the integration of industrial capabilities throughout Europe! Although these developments and enhancements will not immediately affect the army fighting bloody battles on the front line in a short period of time, one day, these things will become the cornerstone of the invincibility of the German army.
