Ferrengi Dreadnaught

The Ferrengi Dreadnaught is the second most powerful Ferrengi vessel in the fictional TradeWars 2002 universe. It can only be acquired by attacking and capturing a Ferrengi ship. Evil-aligned players sometimes use the Dreadnaught as an invasion ship, since it is the most powerful photon-carrying ship besides the Imperial StarShip, which is only available to good-aligned players with a Federal Commission.
