Seems to my recollection that there are several ToobYu vidz of corvettes "throwing" depth charges with a Y-gun, and the plates you speak of do go with the charge, sometimes separating as they fly... but I do not recall if the Y-guns themselves are in the vidz. Maybe a search on "depth charge attack" or something similar might yield results?
... and, of course, they don't know what a depth charge what a hedge hog what a squid is... lol
