Was a “harpoon” responsible for the damage?
It has been pointed out that if the tanker was hit above the waterline it could hardly be a torpedo and crew members reported something flying. It seems likely that the weapon was a submarine launched harpoon attack. The harpoon has recently been re-commissioned after successful trails.
“……typically if you shoot a Harpoon and it
hits above the waterline it’ll punch a hole
and blow up but it won’t sink a ship”.
