Capital ships may travel either by stargate or by using jump drives, which require another ship to create a "Cynosural Field" which the capital ship can then jump to. While this allows the capital ship to travel instantaneously, it requires a trusted second party (or an alternate account) to create the beacon. Jump drives also consume fuel (in contrast to stargates, which require nothing), drain the ship of its capacitor, leaving it nearly defenseless until it is recharged, and incur "jump fatigue", which prevents the pilot from jumping for progressively longer periods of time after each consecutive jump. Titans are also capable of allowing other ships to instantaneously travel by creating temporary bridges to cynosural fields. Black Ops battleships can create similar, but undetectable, bridges capable of transporting only specific types of stealth ships such as Stealth Bombers.
