today I spent some time on Tribble, to figure out what the Fleet Kits from the Embassy and the Spire will be like starting with Season 9.
If you haven't had a Fleet Kit prior to Season 9, you may be sorry now. As it turned out, a pre-Season 9 Fleet Kits can be traded in and you get the same Fleet Kit back, but with 5 rare to very rare Kit Module. If you are going a to buy a Season 9 Fleet First, then you get it with just one Kit Module pre-equipped.
The following chart, let you what opportunities the Kits will give you. Please note, that the indicated Dilithium cost includes already the Dilithium discount from a T3 Dilithium Mine.
The Engineering, Science and Tactical Module represents a universal career-specific Module Slot, allowing you to slot any career-specific Module.
More info about the Kit revamp is available in the Season 9 Dev Blog #7.
