Fleet Alert is a 5 players-event in which must defend a fleet starbase from a random enemy fleet. It can be accessed through the PvE queues and has a 30 minute cooldown.

During Shuttle Weekend Events, this mission is also available as 20 players-shuttle mission.


A fleet starbase is under attack from a randomly selected enemy faction. The team will have fifty seconds to read the briefing, then enemy ships will warp into the system. There are four waves, each consisting of two large groups of ships. The team has ten minutes to defeat all eight groups, after which a final "Siege Group" - led by a named dreadnought - will warp in. The team must destroy the siege group within three minutes to successfully complete the mission.


Mission Text[]

Long-range sensors show a hostile fleet approaching a starbase. Report there immediately and take up arms against the enemy!
