Advice for Fighting Enemy in War

[gustn_toh]

I am playing my first game in Stellaris, and got attcked by neighbor. His army has 11 Battleships, 12 Cruisers, 17 Destroyers and 45 Corvettes, with the designs in the attached figures.

Do you have any advice on how I should redesign my fleet to fight this enemy? I have less battleships than him, but more of all other ships.

Search for the Best Battleship and Best Cruiser threads here. In general:
4 Long range Kinetics 2 Long range plasma/laser on the Battleships - as much armor as you can.
2 Long range Kinetic 2 Medium range plasma/laser on the Cruisers - as much armor as you can
Destroyers should be corvette killers - medium autocannon/.small kinetics - excess energy for higher dodge
Corvettes should be either 1 small kinetic - 2 small plasma/laser - excess energy for higher dodge
of Corvettes should be 1 torpedo - 1 small plasma/laser - excess energy for higher dodge (or maybe a 50:50 mix of the 2 corvette types)
