Due to the destructive potential of dreadnoughts, the Council races agreed at the Farixen Naval Conference to fix a ratio of dreadnought construction between themselves. At the top of pyramid is the peacekeeping turian fleet. Below the turians are the other Council races, currently the asari and the salarians. Council associate races are at the bottom. The human Systems Alliance is part of this last group.
The ratio of turian to Council to associate dreadnoughts is 5:3:1, for every dreadnought the humans are permitted to build, the asari have three, and the turians five.
