On June 7, 1981, eight Israeli F-16 fighter jets, protected by six F-15 escorts, dropped 16 907-kg bombs on the nearly completed Osirak nuclear reactor at the Tuwaitha complex in Iraq. Israeli Prime Minister Menachem Begin and Defense Minister Ariel Sharon saw the reactor as central to Iraqi President Saddam Hussein's quest to build nuclear weapons, and they believed that it posed an existential threat to Israel.
