The ultimate goal of naval warfare is to seize sea supremacy and block the enemy's sea exit and supply at sea.

In some materials on the Iron and Blood Network of later generations, it was introduced that in the Gulf War, the aircraft carrier formation was generally composed of 15-20 ships of different types.

When the aircraft carrier battle group is moving, the front of the water is frigates, destroyers and missile frigates; In the middle is the aircraft carrier; Behind are missile destroyers and missile cruisers; There are a variety of aircraft with different combat functions circling in the air; There are submarines under the water on alert.

This is because with aircraft carriers as the core, a combat group composed of multifunctional ships, aircraft, and their weapon systems will coordinate with each other to form an overall offensive and defensive capability against air, surface, underwater, and ground targets with a tight and large-depth patrol and detection network, a defense network, and a powerful attack capability. Its control radius of air and sea is more than 463 kilometers, and the radius of anti-submarine control is 278 kilometers.

Moreover, the main role of the aircraft carrier fleet in the Gulf War was to carry out interception and blockade at sea and cut off the enemy's economic and armament sources. The second is to ensure the maritime transportation and mobility of the multinational force. The third is to carry out electronic warfare and carry out electronic reconnaissance and suppression. Fourth, it is necessary to cooperate with the Air Force in carrying out strategic and tactical air strikes. The aircraft on the aircraft carrier can carry out strategic bombing and tactical bombing attacks on the enemy's military targets in turn, so that the enemy forces are in a situation where they are unable to fight back.

Fifth, it is to cover amphibious operations and ground operations, because the aircraft carrier battle group can cooperate with the air force and land force to carry out surprise attacks on the military positions of enemy troops; Moreover, the artillery fire on destroyers and cruisers can also simultaneously bombard shore defense targets; helicopter gunships destroyed enemy fortifications in depth; It also successfully cooperated with the army to carry out a strategic feint to contain the enemy's anti-boarding forces, thus effectively covering the landing force and the ground forces to carry out large-scale roundabout operations to divide the enemy's troops......

When Chen Yanlong read the encrypted telegram sent to him by Minister Pentrop, he couldn't help but think of how modern wars were fought in later generations, such as the three-in-one war of land, sea and air, and the lightning attack of the US aircraft carrier fleet and multinational forces in the Gulf War......

"What a pity! If only I had such a powerful aircraft carrier fleet now, then this naval battle in World War II would definitely be the final victory of the German army led by me! ”

After recalling the fighting style of modern warfare in later generations, Chen Yanlong also smiled helplessly and said to himself.

"But even without the advanced technology of later generations, I will win this World War II, especially the naval battle in the Mediterranean, and the naval battle in the Pacific! At the very least, the Japanese army and the US army, the two master and servant countries of later generations, must fight each other and lose their vitality! ”

Then Chen Yanlong also showed a trace of cold light and said resolutely.

Then he picked up the phone and called Speer.

"You immediately rush to make me 300 U-XXI submarines, and my group will first mobilize 200 million marks for you to use as manufacturing funds!"

"If the money is not enough, I will continue to transfer it to you! But I must make it within half a year, no matter what method you use, I have to finish it! ”

"And every week you have to report to me the latest progress in the construction of these U-XXI submarines, and the main VIIC submarines that we are using now, and I will find a way to sell them all to our client countries, the countries of the occupied and neutral zones, as well as to Southeast Asia, and Asia! Because I'm going to eliminate all these groups of submarines that are gradually falling behind! ”

As soon as the phone was connected, before Speer came back to his senses, Chen Yanlong finished speaking in one breath.

"Führer! Don't we already have quite a few ocean-going submarines of the I-400 series? Why is it necessary to be in such a hurry and at such a huge cost to build so many U-XXI submarines? ”

Speer looked puzzled.

"Everything is for the final victory of the war, and the U-XXI submarine is still a good submarine for us now, and it is also a powerful fighting machine, at least it has an underwater speed of more than 17 knots, and its water speed exceeds 15 knots."

At the same time, its large-capacity battery can also ensure that it can dive more than 300 nautical miles at a speed of 5 knots, and there are food refrigerators, showers and other living facilities on the boat that other German submarines do not have. As well as the fact that it is also equipped with hydraulic torpedo reloading equipment, which allows it to fire 18 torpedoes in 20 minutes. ”

"Finally, it is equipped with a new type of sonar equipment, which allows it to aim torpedoes without a periscope, increasing its precision attack efficiency!"

Regarding Speer's doubts, Chen Yanlong immediately replied.

"Anyway I say, you do! Carry out my manufacturing orders, complete my assigned production goals, and never let me down! ”

"Because of this war, we need more submarines to sink the enemy's transport fleet and escort fleet!"

Before Speer could respond, Chen Yanlong continued to add.
