Iran showed off new missile and satellite technology on Monday, and told its enemies it had 'complete domination' of the entrance to the Gulf.

As part of Iran's annual revolution celebrations, a time traditionally marked by new technological and military advances, President Mahmoud Ahmadinejad unveiled locally-made satellites while a senior commander showed off mass produced missiles.

'We should reach a point where we will be able to provide our knowledge and technology in the aerospace field to other countries,' Ahmadinejad said in a speech, unveiling the satellites he said were for scientific purposes, and showing film of a satellite-carrier rocket.

In 2009, Iran launched a domestically-made satellite into orbit for the first time.

The Chief Commander of the Revolutionary Guards, Mohammad Ali Jafari, said the new mass-produced missile would be able to target enemies at sea.   

'Its speed is 3 times greater than the speed of sound and it cannot be traced and deactivated by enemies,' official news agency IRNA quoted Jafari as saying.   

Another Guards Commander, Ali Fadavi reiterated Iran's threat to close the Strait of Hormuz, the narrow channel through which 40% of the world's seaborne oil trade passes.

'The Persian Gulf and the Strait of Hormuz are under the complete domination of the Revolutionary Guards ... and it would be blocked in case of a threat,' he said, according to the semi-official Mehr news agency.

Foreign analysts say Iran would be reluctant to take such a drastic step as it would cut off its own oil exports.
