These operations were conducted to ensure Saddam Hussein was not smuggling his oil out of Iraq, in violation of United Nations sanctions against Iraq. The operations involved the stopping and boarding of any and all ships transiting the Persian Gulf, and the Strait of Hormuz, to search for oil, weapons, and certain fugitives from justice. The first submarine to take part in these operations was the USS Asheville (SSN-758), in March and April 2000.
