The Israeli Navy (, Ḥeil HaYam HaYisraeli (English: The Israeli Sea Corps); ) is the naval warfare service arm of the Israel Defense Forces, operating primarily in the Mediterranean Sea theater as well as the Gulf of Eilat and the Red Sea theater. The current commander in chief of the Israeli Navy is Aluf David Sa'ar Salama. The Israeli Navy is believed to be responsible for maintaining Israel's offshore nuclear second strike capability. History The origins of the Israeli Navy lay in the founding of the Betar Naval Academy, a Jewish naval training school established in Civitavecchia, Italy, in 1934 by the Revisionist Zionist movement under the direction of Ze'ev Jabotinsky, The Academy trained cadets from all over Europe, Palestine and South Africa and produced some of the future commanders of the Israeli Navy. In September 1937, the training ship Sarah I visited Haifa and Tel Aviv as part of a Mediterranean tour. In 1938, encouraged by the Jewish Agency, Dr. Shlomo Bardin founded the Marine High School in Bosmat, the Technion's Junior Technical College. 1943 witnessed the founding of the Palyam, the naval branch of the Palmach, whose training was undertaken at the maritime school. The Jewish merchant marine was also raised, operating SS Tel-Aviv and cargo ships such as Atid. In 1942, eleven hundred Haganah volunteers joined the Royal Navy, mostly in technical roles (12 of them were officers by the nomination agreement of the Jewish Agency with the Royal Navy). A few reached sea service and combat service. Two of them served with the Fleet Air Arm (FAA), one of whom was Edmond Wilhelm Brillant and the other Zvi Avidror. With the end of the Second World War and the start of the Jewish insurgency in Mandatory Palestine, Palyam members took part in clandestine immigration activities, bringing Europe's Jews to Palestine, as well as commando actions against Royal Navy deportation ships. Royal Navy volunteers, meanwhile, rejoined the Haganah. During the last months of British Mandate in Palestine, the former Royal Navy volunteers started work on the captured clandestine immigration ships (known as the Fleet of Shadows) in Haifa harbor, salvaged a few and pressed them into service. These were to become the Navy's first ships and saw service in the 1948 Arab–Israeli War. At the outset of the 1948 war and with the founding of the IDF, the Israeli Navy consisted of four former Aliyah Bet ships
