Nobody else likes to address this, but the ships with their drives are still weapons. If you know where an enemy is (or where their planet, ships, etc are), you can simply jump a ship to that location. The ship won't survive, but you've introduced mass and energy where there previously was none... sending a bomb.

I'm brought back to that scene in one of the later Star Wars movies, where that one Jedi flagship went FTL into the middle of Kylo Ren's stupid mega-cruiser, destroying everything. Why hasn't that been used the entire time? Kamikaze attacks are still attacks.

We don't really have specifics on how the Clone memory logging and data transfer works, but if its anywhere near real time or FTL, then you can send an army of Cleons out to scout, find an enemy, relay that thought to a control center, and jump a bomb ship. You could even just jump a drive strapped to a load of garbage for that extra juicy mass with little extra cost. It's a green alternative to conventional warfare as you get to take out the trash.
