The "Red" resources give combat bonuses when mining star bases (and subsequent mining base upgrades) are constructed upon them.
I've had some trouble nailing down any timing effects of "Red" base creation (and upgrading).
Consider the scenario where one designs a 100 attack ship design and builds three of them, one each on consecutive turns. Call the turns N-1, N, and N+1. If one were to build a Red base (or upgrade) that added 5% on precisely Turn N, would the three ships of the same class be 100, 105, and 105? Or, would they show as 100, 100, and 105?
Would the attack values of each ship in the class remain as originally built? Or, would subsequent Red base upgrades or new red bases, or their loss, change the ship values in "real time"?
Also, do the Red base increases apply to defensive values?
(The same question applies to surveyed anomalies that add combat bonuses).
