Crest/Banner of the Stars have english translations but you will need to google them as they predate novel updates by at least ten years. The Subjugation series by Fel is a great series with lots of space battle
Seikai no Monshou has a full official translation while Seikai no Senki only has translation of book 4
I know man still waiting for book 4 and 5 adaptation(tho it wont happen) I seriously need someone to translate the other volumes of senki.....
