Dark Fog farm, surrounding the polar region of a planet.

The 8 Holo Beacons are placed inside the containment zone, those will eventually be used as a landing zone for a planetary base. In front of each potential base is a Signal Tower that makes sure the base it is facing is permanently aggroed.  8 bases are planned on the planet, 2-3 more can land in the empty space near the pole, and them launching assaults are the most taxing on the defenses.

A set of 8 BABs is repeatedly duplicated along the border, collecting 54 types of drops (excluded: hydrogen, deuterium, hydrogen fuel rods, logs and plants, foundations)

All drops are funneled to a storage to be distributed by Logistic Bots.

It goes without saying you need to have the vertical conveyor upgrade for this setup to work.

A couple Logistic distributors are used to request the following: Laser turrets, Implosion Cannons, BABs, Missile Turrets, Gauss Turrets, Signal Towers, SR Plasma Turrets. All of those are funneled to a BAB making sure to replace any tower that gets destroyed. Only Laser Turrets, Implosion Cannons and Signal Towers are used in this particular setup, When i made the blueprint, my Enhanced Structure level in the tech tree was 24, it should work for lower levels but remain vigilant.

At the current level, the setup uses roughly 300 shells per minute, i have only made one input, you can choose which tier of shell you will use, the input prioritizes the highest tier first. The basic shell set should do the job on its own, and it only uses coal and copper as primaries.

When placing the blueprint, try to have 6100 logistic bots (31 stacks), otherwise you will never find which distributor doesn‘t have bots

I have also made a shield blueprint that would ensure roughly 77% of the planet is covered so no planetary base can land outside the polar circle:
