Over the weekend, the Islamic Republic of Iran test-fired two ballistic missiles into the Gulf of Oman, with one sinking a floating barge approximately 155 miles away, according to Fox News.
The first missile was fired on Saturday, but missed the target. A day later, a second attempt was made successfully.
The two short-range ballistic missiles originated from Islamic Revolutionary Guard Corps bases in Bandar-e-Jask, Iran.
"It's a concern based on the range and that one of the missiles worked," said a defense official.
Two years ago, Iran held a similar exercise destroying a large barge designed to look like an American aircraft carrier.
In February, Ali Akbar Velayati, advisor to Ayatollah Ali Khamenei, made it clear that Iran has no plans of slowing down its nuclear program. The aide to Iran's supreme leader ripped an "inexperienced" President Donald Trump and assured the world that his country would continue ballistic missile testing.
"This is not the first time that an inexperienced person has threatened Iran," Velayati said. "Iran is the strongest power in the region and has a lot of political, economic and military power ... America should be careful about making empty threats to Iran.
"Iran will continue to test its capabilities in ballistic missiles and Iran will not ask any country for permission in defending itself," he said.
