The Dreadnaught Sabre was the flagship of the Krieg Pirates' armada.
The Dreadnaught Sabre was a very large galleon ship, almost triple the size of the ocean-going restaurant Baratie. It had the figurehead of a saber tooth tiger. After returning from the Grand Line, the flagship was in a total wreck, to the point of being compared to a ghost ship.
Serving as the flagship of Krieg Pirates, the Dreadnaught Sabre sailed into the Grand Line. It did not last very long, being attacked seven days after its journey by Dracule "Hawk-Eyes" Mihawk. The flagship barely survived while the rest of the forty-nine ships of the fleet sank due to a storm, and Krieg and his crew returned to East Blue, with the ship becoming a total wreck. Although Mihawk pursued and came along to slice through the ship "for fun," it eventually sunk, and the remains became a battlefield for the fight between Monkey D. Luffy and Krieg. Krieg had mentioned that he intended to sink the ship himself as it was an utter wreck, and replace it with the Baratie.
- "Dread naught" means 'fear nothing' and can refer to the predominant type of 20th-century battleship.
