An Angel Class space station is an enormous space station designed by the Alliance to orbit planets or hang in deep space.
They can house over a million people and work as bases for Star Command and civilian craft.
They are designed to have interior space docks that dozens of starships can inhabit at once so engineers can work on them without exposing themselves to the dangers of space.
They are usually named for months of the year and the Fleet they come under (E.g Station September White comes under the White Fleet.)
