Has any Close-In Weapon System (CIWS) successfully intercepted and shot down a missile in combat? Surely they have had the chance to, for example Phalanx systems were deployed to Iraq and Afghanistan. But besides mortar shells, are there any confirmed successful intercepts against rockets and missiles?
Although both the Close-In Weapon System (CIWS), and its land-based counterpart Counter-Rocket, Artillery, and Mortar, (C-RAM) have both been deployed in combat zones, I can find no record of either system being used to defend against an actual attack by rockets or missiles.
There was an incident during the 1991 Gulf War where the Phalanx CIWS engaged what was believed to be an Iraqi Silkworm missile, but that turned out to be a false alarm.
(A few weeks earlier, HMS Gloucester had used a Sea Dart missile shoot down an Iraqi Silkworm missile that was targeting the battleship USS Missouri. This is believed to be the first successful missile vs. missile engagement at sea in combat).
