I think the categories need to be cleaned up a little. It seems kind of redundant to have
Categories: Spacecraft | Naval ships of Manticore | Royal Manticoran Navy | Havenite Military | Republic of Haven Navy | Ship Types
You could probably condense the national categories into Manticore and Haven.
Naval Ships of Manticore encompass just ships, while the Royal Manticoran Navy encompass ranks, technology, personnel, equipment, but we can use only one for each. It is the same logic for Havenite Military and Republic of Haven Navy.
