According to Almog, the effect of the October (Yom Kippur) War in 1973 on Israel's navy was negligible. Assumptions and contingency plans formulated prior to the war proved accurate.
A coordinated surprise attack by the Egyptian and Syrian navies on 6 October 1973 left a heavily outnumbered Israeli Navy to fight simultaneously in two separate seas: the Mediterranean and the Red Sea. Within a few hours of the war's outbreak, the Israeli Navy responded by executing three separate offensive attacks—offshore Latakia, Syria; offshore Romani, northern Sinai; and inside Mersa T'lemet in the Gulf of Suez. These strikes were decisive and dictated the course of the war.
