Report on C-802 attack
From the blog In From the Cold. Interesting information unlikely to be made available elsewhere for a while.

Like your humble correspondent, the Israeli source is now retired (he spent more than twenty years in the IAF), but has a large number of contacts in Israel's military and intelligence establishment.

"We screwed up," is his blunt assessment of the attack on the Israeli vessel. He tells me that Hizballah operated the surveillance radar associated with the C802 for more than 24 hours before the missile was launched. The radar's signal was detected by Israeli SIGINT platforms, but somehow, the information was never relayed to the ships enforcing the blockade off the Lebanese coast. The corvette's anti-missile defenses were active as it patrolled off Beirut, but my source questioned whether the crew was fully prepared for the missile strike. "They weren't in the proper frame of mind for an attack," he complained. You can draw your own inferences about the ship's readiness posture from his statement.

A retired U.S. naval intel specialist believes the corvette had "up to 15 seconds of warning" between the time the missile was fired, and the moment it impacted the ship. That may not sound like much, but in an era of automated missile defenses, the crew still had a shot. Officially, the Israelis haven't revealed if the ship launched chaff, maneuvered, or attempted to engage the missile with its CIWS. From what I'm told, the missile struck a glancing blow to the large "helicopter" barn on the ship's stern, and bounced off, detonating in water nearby. The barn area was thoroughly scorched by a subsequent fire, and this is the area of the ship where the four crew members died. As we've noted previously, the ship was lucky that it didn't take a direct hit from the C802; the missile is more than capable of sinking much larger vessels.

The impact in the ship's helicopter "barn" is also signficant, since its rectangular shape provides the largest (and best) return for the missile's targeting radar.
and that raises another question: did the Hizballah gunners time their launch carefully, to coincide with a turn (when the barn would be most visible), or was the ship's captain attempting to maneuver after his missile warning system sounded, and inadvertently exposed the helicopter hangar, faciliting missile lock-on. If the terrorist gunners timed their launch for a predicted turn, then the corvette was probably being too predictable in its maneuvers. Additionally, there is also the possibility that the ship's position may have masked its Close-In Weapons System (CIWS), which can engage anti-ship missiles at ranges out to one mile. One more lesson learned the hard way.
