I doubt that there will be a replay capability of tactical battles. Mainly because I really doubt that the computer actually "fights" the battle. In most games such as this, instant tactical combat is merely a calculation of various offensive and defensive factors, comparing weapon strenghts, ranges, defensive armor, shields, number of weapons, etc. I know there appears to be a battle fought quickly onscreen, so perhaps I am wrong here, but most games do it this way.

And yes, you can choose tactics and formations - I think you can find it on the "Fleets" screen.
