The new missile design has a range of 1,200 miles, according to a Reuters report. State broadcaster IRIB quoted an Iranian commander who stated that the country would not seek "permission" for future weapons tests.
“On the path to improve our country’s defensive capacity we will certainly not be the least affected by any threats and we won’t ask anyone’s permission,” Brigadier General Amir Hatami said.
State television added that the missile was Iran's most powerful ballistic missile yet.
“The weight of the Khorramshahr missile’s warhead has been announced to be 1,800 kg (4,000 lbs), ... making it Iran’s most powerful missile for defence and retaliation against any aggressive enemy,” IRIB reported.
Iran's last missile test was in February, an action that resulted in a new wave of sanctions from the Trump administration in July. At the time, President Trump tweeted that his administration would be less "kind" to Iran in the face of such tests.
The U.S. announced additional economic sanctions against Iran over its ballistic missile program and destabilizing actions in the region in July.
The latest test from Iran comes just weeks after North Korean tested its own ballistic missile, firing a missile that travelled over Japan and landed in the Pacific Ocean.
"Iran is playing with fire — they don't appreciate how ‘kind’ President Obama was to them. Not me!” Trump tweeted in February. The White House has yet to respond to this latest test.
