Logistics ship

I don't know what possessed me but to, but I thought it would be cool to build a logistics ship to take over alot of the mining,refining, and grinding that alot of people put on their ships and run it closer to real life. It's still a work in progress smaller frigate is for scale. It's honestly around 300km long 3 landing pads for dropping off ore, 3 large hangers that are gonna have 2 large mining ships and a large grinding ship and has bobs ever 75km. It has 7 large cargo containers and think 7 large hydrogen tanks. It's not a front line fighter but it can hold long enough to bounce with 3 jump drives. It's sitting at 16.3 million kg empty and I'm trying to cut the weight but hard when you need to build a functional bridge
