Ship Designs Guide
To beat bases you need really heavy frontal armour. I think any end-game weapon will work, but what I found worked for me was coilgun dreads with 160 armour and at least 1g combat acceleration. Start in short or high wall formation. You give each dread a different defensive module as a priority target, and keep accelerating. Your dreads get into range to shoot early, and build up a wall of shots that smash through PD and destroy the modules really fast.
You have less overkill because they’re all shooting at different targets. And the medium coil batteries finish off any surviving modules.
If there are no alien ships at the station at all, you’ll start in range of the defensive modules. So you’ll be going a little slow. Normally there’s a small defensive fleet that I deal with first however, and then start accelerating after they are dealt with.
If it’s a massive fleet, I just kill what I can and usually I can use the button up top to withdraw and either heal up or prepare to go again.
Example of a Ship
This is what I used. There are plenty of different designs and optimisations though. Some people swear by using the nose for PD with laser cannons and having more medium batteries. I personally think the small nose cannon is pretty useful as it hits really hard, and often your long range shots will miss anyway:
I used 8 of these to take on alien base with 4k fleet guarding it in 2046. First I turned all my ships around burning backwards from the station and dealt with the fleet, and only then dealt with the station. Lost 5 of them, but since it was my first time trying to attack the station I wanted my ships to be replaceable and not strain my resources.
