Upgrading a Level 1 naval base to a Level 2 naval base required 1,000 military merits and an hour's time!
After the completion of the Level 2 naval base, Yu Zhiqian found that there were many more options for ships that could be built!
This included the New Orleans-class heavy cruiser that he had just dispatched!
The ships that could be built in a Level 2 naval base were below 20,000 tons!
At this moment!
Yu Zhiqian roughly understood the relationship between the level of the naval base and the ship's weight.
He spent 2,000 military credits to upgrade the Level 2 naval base to a Level 3 naval base in eight hours!
As expected, after the completion of the Level 3 naval base, Yu Zhiqian realized that he could build naval ships that weighed less than 30,000 tons!
However, Yu Zhiqian was not interested in ships that weighed less than 30,000 tons!
He continued to level up, and the military points required doubled again, reaching 4,000 points. At the same time, he needed 24 hours!
One day later, Yu Zhiqian would spend 8,000 military credits to upgrade the Level 4 naval base to a Level 5 naval base. It would take 72 hours!
Five days had passed since the completion of the Level 5 naval base. It was now August 8th!
At the same time, Yu Zhiqian could now build warships that did not exceed 50,000 tons!
For example, the Iowa-class battleship!
The Iowa-class battleship had a displacement of 55,000 tons, and the standard displacement was 49,000 tons. Therefore, a Level 5 naval base could be built!
At the same time, Yu Zhiqian also discovered many aircraft carrier options!
After thinking for a long time, Yu Zhiqian did not choose to build an aircraft carrier!
They decided to wait, at least until 1940, when the battleships of the various countries were almost finished!
An aircraft carrier had a huge advantage over a battleship. Anyone who knew a little about military affairs would know this. The 70,000-ton Yamato was bitten to death by an aircraft carrier. The same was true of the war chariot country's Bisman. Therefore, in the later stages of World War II, the battle of the sea was fought with aircraft carriers!
However, it was only 1937, and no country had realized the importance of aircraft carriers. Yu Zhiqian would not take the initiative to release the concept of aircraft carriers fighting battleships!
This would consume most of the country's funds. After all, even the richest John Bull could only launch four battleships a year at most!
Because battleships had high requirements for the various performance of the shipyard, the cost was very expensive!
As for aircraft carriers? Because the carrier-based aircraft now used a piston-type engine, the requirements for the take-off and landing environment were not high. Therefore, a 10,000-ton freighter could be slightly modified into an aircraft carrier that could take off and land carrier-based aircraft!
In this case, even if it was the Japanese, as long as the number of aircraft carriers could keep up, they could continue to build aircraft carriers like dumplings! This was what the Japanese did in the later stages of World War II. They changed merchant ships into aircraft carriers!
Therefore, Yu Zhiqian did not intend to give up his advantage at this time!
He was prepared to continue playing with battleships, and he wanted to let the majority of the world see the power of battleships. He wanted to drag all countries into the tide of building battleships and delay the opponent's economic and technological tree as much as possible!
When the opponent's battleships were almost finished, he would continue to build aircraft carriers like dumplings!
At that time, the battleships that the enemy had spent a lot of manpower and resources to build would be a huge target in front of the aircraft carriers. They would have no place to cry!
Ever since 1937, the enemies in Yu Zhiqian's heart had never been just the Japanese!
The Japanese were not the only country that had suffered humiliation from planting flowers. Yu Zhiqian remembered this clearly!
Although some countries were now allies with Hua Zhong, Yu Zhiqian did not intend to let go of the things they had done in the past!
That was why Yu Zhiqian had resolutely ordered the firing of the cannons at the Shanghai port. At most, he would collect some interest!
Yu Zhiqian was prepared to pay back the countries he had invaded and plundered!
Furthermore, it was the same sentence that they had always said. The caliber was justice, and the range was the truth!
However, Yu Zhiqian had two choices now!
There were two types of battleships that could be built!
One was the Iowa-class battleship, which required 49,000 military credits. The military credits needed to build the battleship were equivalent to the displacement of the battleship!
The other choice was the Bisman-class battleship!
The two battleships were the pinnacle of the battleships of World War II. Together with the Yamato class, they were known as the three great battleships!
Compared to the Iowa-class battleships, the Bismann-class battleships had a smaller caliber. They were equipped with four 380mm main cannons, which were 52 times the diameter!
Apart from that, there were also six 150mm secondary cannons and eight 105mm anti-air cannons!
However, its armor protection was much higher than Iowa-class!
The speed was also about the same!
At the same time, Bismarck's defense against torpedoes was better. In terms of cost, Bismarck only needed 41,000 military merits, which was 8000 military merits lower than the Iowa-class!
