No weapons were fired in defense of "Stark". The Phalanx CIWS remained in standby mode, Mark 36 SRBOC countermeasures were not armed until seconds before the missile hit. The attacking Exocet missiles and Mirage aircraft were in a blindspot of the STIR fire control director (Separate tracking and illumination Radar, part of the Mk 92 Guided Missile Fire Control System), and the Oto Melara Mk 75 76 mm/62 caliber naval gun, but in the clear for the MK 92 CAS (Combined Antenna System, primary search and tracking radar of the Mk 92 Guided Missile Fire Control System) and the Mk 13 Mod 4 single-arm launcher. The ship failed to maneuver to bring its Mk 75 to bear before the first missile hit.
