And mini-torpedos have never appeared in any way, shape, or form in Star Trek Canon as far as I know.Picard wrote:Runabouts, shuttles and fighters fire smaller micro-torpedoes. Normal torpedoes are 2.1 x 0.8 meters if I remember correctly - in any case, large enough for average person to fit inside when sub-components are removed. That is bit too large for runabouts or fighters to pack anything more than one pair of them.
I'm well aware of what Star Fleet has done with the class 8 probe. You have to love proof that the UFP can make warp drives capable of reaching warp 9 and small enough to mount on torpedos without needed to remove any components.
