Battleships can be up to 8 kilometres from prow to stern and displace billions of tons. Imperial battleships can have crews of anywhere between 25,000 to 3,000,000 or more depending on sources, including large numbers of Imperial Navy armsmen to defend against enemy boarding assaults. Although very powerful, battleships are very slow to manoeuvre and cannot react quickly to enemies that rapidly change course. Battleships are huge vessels, with colossal amounts of weapons and shields, and usually serve as the flagship for the Admiral of the Fleet, though this is not always necessarily the case.
