I too remember reading that somewhere. One Sovereign-class each cycle, and then a batch of Destroyers. That means there are still roughly 18,000 Reaper capital ships, with many more destroyers. The quarian fleet took out a Destroyer without sustaining any losses in the act, so they need not be included in the calculation of the number of fleets required.
