The Israeli naval command had reached the conclusion by the early 1960s that their old Second World War-era destroyers, frigates and corvettes were obsolete and new ships and vessels were needed.[3]Yitzhak Shoshan, later to command the destroyer INS Eilat at the time of her sinking, surveyed the available torpedo boat designs and recommended the German Jaguar class.[4] The Israeli Navy asked Lürssen, the shipyard which built the Jaguar class, to modify the wooden Jaguar-class design by switching to steel construction, adding 2.4 metres (7 ft 10 in) to the length, and revising the internal compartmentalization.[5] Due to Arab League pressure on the German government, this plan was not continued and a new builder was sought.[6] The Israeli Navy discovered that the Cherbourg-based Constructions Mécaniques de Normandie owned by Félix Amiot had experience building patrol boats in cooperation with Lürssen and would build the boats, based upon the German designs and plans.[7] The engines were imported from Germany.[8] The project received the code name "Falling Leaves" (Hebrew: שלכת).[9] After the last 5 built were placed under embargo by the government of France, they were retrieved in the Cherbourg Project.
In the 1980s, one of the Sa'ar boats got stuck in the Coastal waters of Saudi Arabia. Saudi Arabian authorities allowed the Israeli navy to free the ship and to take it away.[11]
