The high speed WWII battleship Iowa class has been a contemporary aircraft carrier with a maximum speed of around 33 knots Why is the speed set at 30+ knots?

There are two criteria for the speed of a warship, one is the maximum speed and the other is the economic speed. For military vessels, speed is a very important performance indicator, the faster the speed means that the faster the speed into the battle, the speed of warships in consideration of the fast and slow at the same time also need to balance the sustainable endurance, the carrier's maximum speed is set at 30 knots is to balance the speed and endurance of the choice between the carrier in the maximum speed is still able to maintain a minimum time-sensitive combat capability.

Replacing conventional carriers with high-speed models is certainly necessary, and Sun Tzu said that the speed of the soldier is precious!
