This is what CR said about the Redeemer and the new modular system:

For example: if you have purchased a Redeemer, then using the new system you would have a variety of new modules available to refit the ship, internal and external, to suit your play requirements. If you wanted to make it a Bounty Hunter ship, you could buy a “Stasis Chamber module” for the lower deck and you would be able to capture and store fugitives to be delivered for their bounties at your leisure. You could configure the upper deck to be outfitted with a “long range communication suite” allowing you to keep in touch with your “Infoagent” even when in deep space. Fed up of Bounty hunting? Swap in a larger cargo module in the lower deck to make that profitable run you have been planning for a while, or add the Explorer Module with deployable vehicle for some planetside recon.
