Hello,

 Maybe this could go in the bug report forum, but you can move the thread if it's a concrete misfunction of the game.

 Just created a big missile ship but it does not fire, at least, when I look at the fight, it just does nothing ...

 In order to test yourself :

 Load the game using the following saved game : BuggedBattle.sav
 Do the ship fight in the system of Kais, choose the tactic "Analyse post-op" (+25% xp).  By defaut, it proposes to put the ship of the hero + the big one (BigMissile) in position 1, and the 2 others in position 2.  The position one is for long range, good for missile.  The computer choosed the 70% increase in crit tactic.
 Then start the fight and look at it.
 During all the fight the big missile ship is always at long range, but it does not fire at all, no missile.
 Is it normal ?

Cheers

A known bug. Look here: http://steamcommunity.com/app/392110/discussions/0/1496741765125447113/

This needs an immediate hotfix, as it makes the game unplayable.

Seems recent, maybe a new bug which appeared with the last patch - devs will know the answer, and I hope to see a quick fix about, as the fix to solve the speed of the ships which seems also to be randomly broken.
