Iran has tested new Russian-built air defenses, as part of two-day war games off the Persian Gulf and Sea of Oman.
Iran's Revolutionary Guard commander, Brigadier General Hossein Salami, told state-run media that the military and air force are "enhancing the defensive capabilities." He said they test-fired their new Russian defense missile system called TOR-M1.
Russia completed delivery of the system last month.
Wednesday's test comes as the United States moves a second aircraft carrier to the Gulf. U.S. Defense Secretary Robert Gates said Friday the Bush administration is not planning to go to war with Iran.
The United States and other Western nations accuse Tehran of seeking nuclear weapons. But Iran maintains its nuclear program is solely for peaceful purposes.
