What if the swarm invades? Bug solution of swarm invasion

The more advanced the laser weapon, the more effective it is. The swarm uses natural heavy armor, so it is not afraid of missiles. They are afraid of high temperature, so they use lasers. It is suggested to use 30 frigates with 15 destroyers and 5 battleships for fleet configuration. Battleship is equipped with some defenses, which can effectively repel insects (insects like fighter planes). However, even if insects are driven away from the infected planet, they can no longer survive. Answering questions for the first time may be insufficient. If you are satisfied, please adopt it.
