Several news organizations have posted stories--apparently sourced to
a single AP report attributing the comment to an Israeli
official--saying the device that hit the Israeli ship off Lebanon was
an Iranian-made C-102 missile, and that technical assistance was
provided directly by Iranian troops.

Now I've found a Jerusalem Post article saying the missile was an Iranian
supplied C-802 (not 102 as in the AP-derived articles). The attributed
source is Israeli Brig. Gen. Ido Nehushtan.

The C-802 designation is listed on fas.org, and seems plausible for the
mission.

FAS states that Iran was believed to have had dozens of this type procured
from China almost a decade ago, and to have been working on an indigenous
derivative more recently.

M 0.9, 120 km range, warhead 165 kg HE

Any better references out there?

That size warhead seems formidable in attacking a missile patrol boat. I'm
just assuming the Israeli warship was of that general class, as I think
they dominate the Israeli surface naval combatants list.
