(The Elisra EW suit is actually a derivative of Lockheed Martin's F-16 I Sufa (Storm) self-protection suite ? itself a derivative of the Boeing F-15 I Ra'am (Thunder) self-protection suite. Elbit HeliCom command and control mission management system overlaid on a moving-map display (MMD)and integrated with the Elbit Integrated Helmet and Display Sight System (IHADSS)."
