On the eve of the Yom Kippur War, the Navy was perhaps more ready for combat than any other part of the IDF. When the war began, Navy ships and men were on full alert and at stations. Despite the fact that the Israel Navy was smaller in size than the enemy navies, it carried out successful attacks on enemy vessels and ports and prevented enemy craft and from attacking Israeli shores..

The following were some of the main battles of the war:

The first sea-to-sea missile battle in the history of naval warfare, which occurred at the entrance to the Syrian port of Latakia, during which 5 Syrian ships, including 3 missile boats, a mine layer and a gun boat, were sunk.

The battle of Port Said, during which an Israeli missile boat sank an Egyptian missile boat.

The battle of Damietta, in which an Israeli missile boat task force intercepted and sank four Egyptian missile boats.

In these battles, the Israeli Dabur (Hornet) missile boat was the main power of the Navy. In the battles of Marse Telemat, De Castro and Ras Arib, the Israel Navy attacked and destroyed enemy vessels. In addition, naval commandos were active in Ardaka.

After the war, the Navy extended its deployment of missile boats to Sharm-e-Sheik which enabled the Israel Navy to conduct operations further south. At the same time, the Navy was involved in intensive activities on the northern front due to the infiltration of terrorists and intensification of security patrols. For this purpose, the Navy acquired a new generation of submarines (Gal) – new missile boats built in Israeli shipyards, and Harpoon sea-to-sea missiles.

The period between the Yom Kippur and Peace for Galilee Wars (1973-1982) was one of increased terrorist activities against Israel. This required the Navy to find suitable solutions, based on intensive patrol operations along the coastline.
