Late-game hulls in Moon are a research plan, not a shopping list. Black Moon wants Shipyard 15, Graviton 3, Laser 20 and Hyperspace 10 before it'll even build; Battle Cruiser (Shipyard 8, Laser 12, Hyperspace 5) is the honest mid-game target. Pick the hull first, then work the tree backward. Free space strategy in your browser: https://moonsiege.com/?ref=1&src=snapie
