General Mohammad Ali Jafari, said last month that Iran's 1,200 mile plus missile range could cover "most of American interest and forces" within the region, so Iran did not need to extend it.
The country has one of the Middle East's largest missile programmes, including precision-guided missiles that could strike Israel.
It comes after France called for an "uncompromising" dialogue with the Islamic Republic about its ballistic missile programme.
However Iran has repeatedly said its missile programme is defensive and it will not negotiate on it.
The United States has accused Tehran of supplying Yemen's Houthi rebels with a missile that was fired into Saudi Arabia in July.
It has called on the United Nations to hold the country accountable for violating two UN Security Council resolutions.
Iran denied supplying Houthis with missiles and weapons.
In October the National Council of Resistance of Iran compiled a report showing Iran is developing weapons of mass destruction.
People's Mojahedin Organisation of Iran has been monitoring Iran's nuclear program since 1991.
It has accused the regime of continuing to bolster its capabilities, including working on "various stages of enrichment, weaponisation, warheads, and delivery systems".
The resistance has also said the Iranian military is hiding the country's program in a bid to trick weapons inspectors.
