ian missile boats. An Egyptian positioned within the harbour at Port Said fired two missiles at the Israeli destroyer. ''Eilat''s radar did not reveal any suspicious activity or movements because the Egyptians launched the missiles from within the port. ''Eilats captain ordered evasive action when the missiles were detected, but the first missile hit the ship just above the waterline at 5:32 p.m. Two minutes later the second missile struck, causing additional casualties. While ''Eilat'' began to list heavily, the crew tended to the wounded and engaged in rescue and repair operations while waiting for additional ships of the Israeli Navy to come to their rescue. Approximately one hour later another Egyptian Komar-class missile boat from Port Said harbour fired two more Styx missiles at ''Eilat''. The third missile hit ''Eilat'' amidships, causing more damage and further fires, while the fourth went astray and crashed in the water nearby. ''Eilat'' sank about two minutes later. Out of a crew of 199, 47 were killed or missing and 90–100 were wounded.

throughout the world. Though not highly publicized at the time, the sinking had a considerable impact on the Israeli Navy. Israel started to develop plans for German-influenced ship designs better suited to missile combat, principally small and efficient boats armed with missiles, able to patrol Israeli shores and undertake offshore operations at high speed, while at the same time able to evade enemy tracking and missiles. The resulting focus on new, more agile, missile-armed boats (see '' Sa'ar 2-class missile boat'') would reap major benefits for the Israeli navy six years later during the Yom Kippur War
