My promethium ship. 32k tons.
Two ships run alternately to handle 30kspm.
It will turn around at about 550,000 km. At that time the operation is heaviest and UPS drops to about 35.

To improve UPS, I would like the next ship I create to have a steeper diagonal angle like yours.

That is awesome. I wondered if a wedge or pyramid would be optimal. Curious what is the capacity and how quickly is it filled by the wedge setup?

In terms of UPS optimization, I expect a sharp wedge shape is better. For UPS optimization, I try to minimize promethium take-up as much as possible. This is also why I want to make the angle steeper. Other than that, I slow down as I go deeper. And try not to read items on belts, as reading them lowers UPS.

I don't know the exact number, but a ship in its current form brings back about 1.8M promethium in one voyage.
=Promethium SP 2.16M

Top speed 290, cruise speed 150, weight 286tons, width26 tiles. (speed is heavily influenced by width of the ship)
The most interesting is crusher & resource system. It mostly use all sources, discard over board is possiblee, but very seldom. Well only thing thrown overboard regularly is used fuel cell.
The crasher system selects most needed items of three (iron ore, carbon, cubes) then assign 2 crushers to it. Next two crushers are used for next two items needed. OR next two crusher are used for first item if it is the only one missing thing. OR next two crushers are used for one item if only two items are missing.
Long story short, it tries always crush something which is needed (max of each 3 item is capped on 200 pcs) and use as many crushers as possible.

Also interesting system is, the crushers are fed from two sided, belt and hub. Each of them has his own system managing overflow /underflow.
Four collectors are of course set to gather resources in ratio 1:1:1, storing 13 pcs of each inside.
