well, dock power supply and shield supply INSIDE of the planet core, and build inwards.
Then spawn a
wave of 20 of these things. If your docked satellite network (for looks and AMS!) and land based turrets can kill all of them, you are probably solid for nearly everything.
Make sure to have a mix of long range and short range weapons, and plenty of decoy missiles from maybe 1 block missile beams so the huge missile beams (your long range guns) can slip through point defense.
