Today, my mother took me to the city cultural center to visit the national defense education exhibition of space model aircraft.

As soon as I entered the exhibition hall, I was attracted by rows of space navigation models, including planes, warships, tanks and aircraft carriers! I can't wait to rush over. The first thing I saw was a warship named "Nanchang", which was the most powerful warship in the surrender war between China and Japan in War of Resistance against Japanese Aggression. President Mao Zedong personally wrote an inscription for it. Then I saw the world's first powered aircraft carrier, the "New uss enterprise", which can carry more than 90 planes, including fighters, tankers, reconnaissance planes and helicopters. I also saw China's first successful manned Shenzhou 5 spacecraft. Its success indicates that China's key technologies in spacecraft and rockets have been in the leading position in the world. ...

I read one by one and remember one by one. There are probably dozens of different types of Chinese and foreign space navigation models in different times. While visiting and understanding these aviation navigation models, I understand that science is constantly developing. As children of the new era, we should study hard and create more advanced national defense weapons to make our country and nation forever strong invincible.
