If you are lucky enough to have a sub (I have 3, sadly they are all Goya so I can only use one at a time =/) you can use a sparkled sub around level 20-25ish to solo the map if you can get the stars to align and such. All ('all') you need to do is damage two of the boss node ships without taking any damage in return and a B-rank clear is yours. Might take a few tries but it is far cheaper and less time consuming than the BB+CV method.
