But the USS Gravely had to use its Close-In Weapon System (CIWS) for the first time since the US began intercepting the Houthi missiles late last year, which ultimately succeeded in downing the missile, officials said. The episode underscores the threat the Houthis continue to pose to US naval assets and commercial shipping in the Red Sea, despite multiple US and British strikes on Houthi infrastructure inside Yemen. Tom Karako, the director of the Missile Defense Project at the Center for Strategic and International Studies, said it was “concerning” that the Houthi missile managed to get so close to a US warship. Since January 11, the US has carried out multiple strikes inside Yemen against Houthi weapons depots, command and control nodes, and storage facilities, military officials have said. Officials have declined to detail what percentage of the Houthis’ weapons capabilities have been degraded by the strikes.
