The ultimate goal of naval battles is to seize sea control and block the enemy's sea routes and sea supplies.

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

When the aircraft carrier battle group is advancing, the front of the water is frigates, destroyers and missile frigates; the middle is aircraft carriers; the back is missile destroyers and missile cruisers; aircraft with various combat functions are hovering in the air; submarines are alert underwater.

Because this combat group consisting of multi-functional ships, aircraft and their weapon systems is coordinated with each other to form a strict large-depth patrol and detection network, defense network and powerful attack capabilities to deal with air, water, underwater and ground targets. Its control radius against air and sea is more than 463 kilometers, and the anti-submarine control radius is 278 kilometers.

Moreover, the main role of the aircraft carrier fleet in the Gulf War is to implement maritime interception and blockade, cut off the enemy's economy, and provide military supplies. The second is to ensure the maritime transportation and maneuver of multinational troops. The third is to carry out electronic warfare and implement electronic reconnaissance and suppression. The fourth is to cooperate with the air force to implement 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, leaving the enemy in a situation where they are unable to fight back.

Fifth, cover amphibious operations and ground operations, because the aircraft carrier battle group can cooperate with the air force and the army to assault the military positions of the enemy troops; and the artillery fire on destroyers and patrol ships can also bombard shore defense targets at the same time; armed helicopters destroy the enemy's deep defense fortifications; and successfully cooperate with the army to implement strategic feints, restraining the enemy's anti-boarding forces, thereby effectively covering the landing troops and ground troops to conduct large-scale detour division of enemy troops...

When Chen Yanlong read the encrypted telegram sent to him by Minister Bentrov, he couldn't help but think of how modern wars in later generations were fought, such as the war of land, sea and air trinity, and the lightning attacks on the Gulf War U.S. aircraft carrier fleet and multinational forces mentioned on Iron Blood...

"What a pity! It would be great if I had such a powerful aircraft carrier fleet now. Then this naval battle of World War II would definitely be the German army led by me to win the final victory!"

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

"But even without the advanced technology of later generations, I will still win this World War II, especially the naval battle in the Mediterranean and the Pacific naval battle! At least, the Japanese and US military, the two master and servant countries in later generations, must be greatly damaged by fighting each other!"

Then Chen Yanlong also showed a cold light and said firmly.

Then he picked up the phone and called Spel.

"You can make 300 U-XXI submarines for me immediately. My group will mobilize 200 million marks to be used as manufacturing funds!"

"If the money is not enough, I will continue to transfer it to you! But I must complete it within half a year, no matter what method you use, it must be done for me!"

"And every week you have to report to me the latest progress in the manufacturing of these U-XXI submarines. In addition, the main VIIC submarines we are using now will give me some solutions to our servant countries, countries that occupy and neutral areas, as well as Southeast Asia, and Asia! Because I want to eliminate all these gradually backward submarine groups!"

As soon as the phone was answered, Chen Yanlong finished speaking in one breath before Sper could come to his senses.

"First of the Year! Don't we already own a lot of I-400 series ocean submarines? Why do we still need to be so rush and cost so much to build so many U-XXI submarines?"

Sperl said in confusion.

"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 combat 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 submarines more than 300 nautical miles at a speed of 5 knots, and there are food refrigerators, shower equipment and other living facilities on the boat that other German submarines do not have. It is also equipped with hydraulic torpedo refilling equipment, allowing it to launch 18 torpedoes within 20 minutes."

"In the end, it is also equipped with new sonar equipment, so that it can aim the torpedo without a periscope, increasing its precise attack efficiency!"

Chen Yanlong immediately answered Sperer's doubts.

"Anyway, I say, you do it! Do not disappoint me if I implement my manufacturing orders and complete my designated production goals!"

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

Before Sper's response was met, Chen Yanlong continued to add.
