NOTES:
Known Sphere Of Operation: Dominion controlled space
Data Reliability: E for all models
Major Data Source: Cardassian Sector Intelligence
Less than 100 of these ships are known to have crossed into the Alpha Quadrant. However, these vessels appear to have been quite prevalent in Dominion controlled space within the Gamma Quadrant. Captured documents indicate that the Extinguisher class is no longer in production; however, over 600 of these ships are known to have been built. 16 Alphas, 3 Betas, 7 Deltas, 13 Epsilons and 69 Gammas have been destroyed. 6 Alphas, 1 Delta, 2 Epsilons and 11 Gammas have been captured. 4 Alphas, 3 Deltas, 1 Epsilon and 4 Gammas are listed as missing. 7 Alphas, 2 Betas, 2 Deltas, 11 Epsilons and 49 Gammas have been scrapped (including 30 that were damaged beyond repair in the attack on the Monac shipyards.) Unconfirmed reports indicate that 4 or more of these ships remain in the Alpha Quadrant.
