Its one of these modules that aren't optional, like the FSS. These come with every ship, existing ships got them retrofitted during the galactic maintenance.I would say it seemed odd I magically acquired the Suite. I guess it's priced in, and the Contact has it installed on your ship when you buy, but some part of me feels like it "ought" to be a module you buy that just doesn't consume a slot. Buy the module first then use it with Contacts as you find your desired systems, type of thing. As it stands it seems weird you could use the starter Sidey and make that into Johnny Appleseed without doing much else to stake a claim.
And staking a claim needs besides the funding some severe material backing or the system is free to claim after the claim failed due to lack of it. And the commander who staked this failed claim would have a cooldown period in which they are not allowed to claim another system.
