You can't see it, because you don't have high enough base intel, but the Galleon is simply evading all of your shots. The Large Ancient Macro Batteries you are employing only have 50% Accuracy. On top of that, they only have 5% Tracking. The Galleon you are firing upon has a final Evasion % of 61.4%. In combat, the chance to hit is the result from the following:

(Accuracy + Tracking) - Evasion

So, since your combined Accuracy + Tracking is lower than the enemy's Evasion, you are simply missing every single shot.
