Warship Design - Atomic Rockets

Delta-v is determined by the specific impulse (fuel efficiency) of the ship's engines and the percentage of the ship's mass that is fuel. Tonnage of the ship doesn't really matter here: it is a ratio thing. If the specific impulse is the same and the fuel percentage to total mass the same, any size ship will eventually reach the same final speed.
