Gun, rocket, railgun and artillery turrets (and artillery wagons) keep themselves stocked with the best ammo in reach: construction robots bring it from the logistic network, and on space platforms the hub throws it across. Worse ammo is swapped for better automatically. Works with modded turrets and ammo; never uses nukes.

Furnaces, boilers, burner drills and inserters, locomotives, cars, heating towers, nuclear reactors and biochambers keep themselves fuelled: construction robots bring fuel from the logistic network (the hub on space platforms). Vehicles get the best fuel; machines get the most plentiful basic fuel and never your rocket or nuclear fuel.

Fire capsules of cargo between surfaces: up to space platforms in orbit, back down to the planet, and later across space to receivers on other planets. Each shot needs a capsule and a big charge of power. Circuit-controlled - and a capsule that lands on a full receiver, or on nothing at all, explodes and its cargo is lost. Inspired by the delivery cannon in Earendel's Space Exploration (an independent mod, not a port).
