Amir Hatami said the missile hit its target in the Saturday test after travelling 1,200 kilometres (745 miles).
Iranians visit a weaponry and military equipment exhibition in the capital Tehran on February 2, 2019.
Iran insists that its ballistic missile program was not part of the 2015 deal with the U.S., France, Britain, Germany, China and Russian Federation.
Iran has expanded its missile program, particularly its ballistic missiles, in defiance of opposition from the United States and expressions of concern by European countries. "They are wrong!

Israel will do everything possible to counter Tehran's hostile actions for the sake of the country's security as Iran has overtly demonstrated its intention to destroy Israel when unveiling its new cruise missile, Israeli Prime Minister Benjamin Netanyahu said on Sunday.

Iran carried out a failed attempt to launch a satellite into space on January 15, defying a warning from Trump.
France, one of the remaining parties in the Iran deal, condemned the attempted satellite launch and urged Iran to discontinue all ballistic missile tests, which violate United Nations resolutions.

That puts it in range of one of its biggest enemies, Israel.
Last week, Iran dismissed the pressure from France for talks, but said it had no plans to increase the range of the weapons.
Against a backdrop of USA warnings since the Trump administration pulled out of a deal on Iran's separate nuclear programme in May previous year, Tehran has continued to expand its missile programme. Iran will be forced to make a "strategic leap" if European or other countries try to limit its missile might, Brigadier General Hossein Salami, the second-in-command of the Islamic Revolutionary Guard Corps, has said.
