The Saar-5 class has limited anti-missile capabilities. The Barak SAM is a vertical launch command to line of sight missile with the ability to engage two targets at once. There are 2 Sea Vulcan CIWS. The ships are also equipped with chaff dispensers and intercept receivers and jammers. Needless to say the CIWS need to be off when operating the helicopter or when friendly aircraft are near. There was no anticipation that there would be anti-shipping missiles in the Hizbollah OB.
