As mentioned in the header article, Big Heavy is looking to stress the inherent strengths of heavier combat ships (medium and large ships focusing on direct confrontation). Heavy combat ships have high-value activations that can get a lot done. For the amount of space they take up on the table, they can throw an awful lot of dice, and for the most part they can take a lot of punishment, especially if the enemy is unable to gang up on them to overheat their defense tokens. Heavy ships that are only taking one or two attacks each round are in most cases effectively immortal, especially with the right defensive tech; conversely, light combat ships taking one or two attacks each round are going to be destroyed if they can't get out of trouble and soon. A Big Heavy fleet is looking to quickly destroy heavy-hitting opposition that threatens its heavy ships and then hopes to spend the rest of the game casually gobbling up the less-threatening survivors.
