Zheng He's fleet, the largest treasure ship to the west, has a displacement close to that of an aircraft carrier?

The displacement of the largest treasure ship in Zheng He's voyage to the West is not close to that of the aircraft carrier. The current aircraft carrier is much larger than the wooden ship at that time, so the displacement of the aircraft carrier is three to five times that of the previous one. At that time, the wooden boat was about 45 feet long and 19 feet wide, which was equivalent to about1502,000 meters long and 63 meters wide. Under the technology at that time, such a ship was a huge ship, weighing more than 800 tons. In addition, its displacement is about 5,500 tons, but now the minimum displacement of the aircraft carrier is 55,000 tons.

During the reign of Emperor Chengzu of Ming Dynasty, eunuch Zheng He set out from Liujiagang with more than 200 ships, and more than 20,000 people sailed here together. During this voyage, Zheng He reached more than 30 regions and countries. It was a great thing that Zheng He's team could reach so many places when the technology was still very backward at that time. At that time, this voyage was the largest of all voyages in the world.

The ship led by Zheng He needs hundreds of people to drive, and a ship can sit close to 1000 people. But its raw material is wood, and the current aircraft carrier is made of steel and other materials, which makes the displacement of the ship more than 600 years ago far less than the current one, or even one-third or one-fifth of the current aircraft carrier.

However, such a great manufacturing industry at that time was also created by the wit and efforts of our great ancestors. This has made great contributions to our scientific and technological strength and laid the foundation for the later scientific and technological development. Now the success of the aircraft carrier is inseparable from that credit. ?
