Have an idea. It is said that Yu Chao has a semi-submersible speedboat. I've seen it on some Military Day. It's a bit like a canoe for two or three people. People wear clothes to change water.

Germany invented this semi-submersible attack weapon during World War II and attacked it with torpedoes.

And it's not an artificially guided torpedo like Japan.

Theoretically, people can come back after torpedo attack.

However, such weapons, not to mention the trouble caused by machine failure.

1. In order to ride with people, the speed of semi-submersible weapons must give way to people. Why can't the fastest plane catch up with the fastest missile? It is because there are people in the plane that people's bodies can't bear it too fast.

2. In order to be miniaturized, semi-submersible weapons can't be loaded into high-power engines, and the oil load is also small. This determines that semi-submersible weapons have small operational radius and poor cruising ability. In this way, we can only undertake the task of offshore operations.

As you said, it should be carried by ship. However, when it is carried by a ship and attacked with a semi-submersible weapon at a slow speed, it is not as cost-effective as a ship or submarine directly launching missiles to attack enemy ships.

Due to such restrictions, semi-submersible weapons do not appear as offensive weapons on the battlefield, but as delivery weapons in infiltration operations. Carrying special forces into enemy lines to carry out sabotage activities.
