Would have blown the back half off the ship. The drone with 100# of HE is more believable.
Actually reviewing the article, the problem is DUMBKA is too stupid to know that the C-802 missle has nothing to do with a Silkworm...they claim it's in the "Silkworm" family when that is totally false. The C-802 is an Exocet/Harpoon knockoff.
Having said that, I am still waiting to see pics of the stricken vessel.
