The war games, called Payambar-e Azam 3, were conducted by missile units of the IRGC's naval and air forces, Press TV quoted local Mehr and Fars news agencies as saying.
The war games came after IRGC Commander Major General Mohammad Ali Jafari said in late June that Tehran would impose controls on shipping in the strategic Strait of Hormuz if it was attacked.
The United States and its allies have accused Iran of trying to develop nuclear weapons under the cover of a civilian nuclear program. Iran has denied the U.S. charges and insists that its nuclear program is for peaceful purposes only.
The Bush administration said it focused on diplomacy to try to resolve Iran's nuclear issue, but has insisted it will take "no option off the table."
Some observers believe that it is still possible that the United States and Israel would attack Iranian targets for Tehran's suspicious nuclear programs.
