this is a pack of flags from elite dangerous. it has a flag for all the larger powers (imperial, federation, alliance) and most of the ship manufacturers. the logos have been take from the wiki for these entities. most of the flags have transparent backgrounds and are meant to be placed on a ship rather then an actual flag but they are easy, if a bit tedious, to edit. simply drop one or all of the flags into Gamedata/Squad/Flags.
