All ships can participate in E4 but to start from the north (to open node or to clear with north route) you need a fleet with all green tag from E1/E2.

Otherwise all ships with all tags can start from south route (eg a mix of green/yellow/grey/no tag fleet), but if a ship with no tag starts here, she will be tagged yellow so she cannot go from north route nor go back to E1/E2/E3 to farm anymore.
