( CNN ) Iran blasted its mock-up of a U.S. aircraft carrier during naval drills on Wednesday , swarming the target with 100 speedboats armed with rockets , shoulder-launched missiles and mortars as well as striking it with cruise missiles , according to reports from Iran 's semi-official Fars News Agency . Iran said the aircraft carrier target was a full-size replica of the USS Nimitz . `` Iranian naval forces displayed their skills in targeting enemy vessels and destroyed a mock U.S. aircraft carrier during the Islamic Revolution Guards Corps Navy 's massive Payambar-e Azam 9 ( The Great Prophet 9 ) wargames in the Persian Gulf and the Strait of Hormuz , '' read a video caption on Fars ' website . When U.S. officials first learned of the existence of the mock carrier last year , one described it as more akin to a Hollywood set than an actual warship . But the symbolism is clear . Nimitz-class carriers are the centerpiece of U.S. naval forces , and the largest warships in the world . Mine-laying exercises were also part of the war games , according to the Fars report . Rear Adm. Ali Fadavi , commander of the Iranian naval forces , described that portion of the games as `` the most important concern of the Americans . '' `` We have the most advanced sea mines which can not be imagined by the Americans , '' he is quoted as saying in the Fars report . Brig . Gen. Hossein Salami , lieutenant commander of the Revolutionary Guard , said Iran was n't showing off all its capabilities during the games , according to a Fars report . `` We have capabilities which will remain covert and hidden before being used in action and we will merely use them in the battlefield , '' Salami said in the report . A U.S. Navy spokesman in Bahrain told the Associated Press that the United States `` was not concerned about this exercise . '' `` We 're quite confident of our naval forces ' ability to defend themselves , '' Cmdr . Kevin Stephens said . In 2014 : Iran says it built copy of captured U.S. drone .
