Page requires update - 1st wave of reinforcement had 2 destroyers, a number of battlecruisers and three battleships.
2nd wave was two cruisers (Nuker Alvum and Disintegrator Alvum) and two battleships (Domination Alvus and Spearhead Alvus). These spawned at the death of a BC from the previous wave when there were still two battleships (Alvus Controller and Swarm Preserver Alvus) still on grid.
