fleet hangars , store fleets (obviously) which are for taking planets defence then planets.

your MS can only be damaged by another MS , cannot be sabbed

glider squadron is your actual fleets

So fleets are only useful in wars?because we dont steal planets normally.Or do fleets have any advantage to do with normal gaming?

[TimeGap]

Fleets give a nice boost to the total power of the MS, and even when not in war, planet stealing is quite common, especially if you dont really have any big planets, always good to steal one if you happen to spy one better than a current planet
