Gulf of Suez
Israel responded with a counter-blockade of Egypt in the Gulf of Suez. The Israeli blockade was enforced by naval vessels based at Sharm el-Sheikh and the Sinai coast facing the Gulf of Suez. The Israeli blockade substantially damaged the Egyptian economy. According to historian Gammal Hammad, Egypt's principal ports, Alexandria and Port Safaga, remained open to shipping throughout the war. Throughout the war, the Israeli Navy enjoyed complete command of the seas both in the Mediterranean approaches and in the Gulf of Suez.
