The move came after Qassem Soleimani, the head of Iran's Revolutionary Guards Corps' elite Quds Force, was assassinated in a US drone strike on January 3 outside Baghdad International Airport in Iraq.
Four members of the Iraqi Air Force were reportedly injured in the attack, which was attributed to Iran-backed Shiite militia.
Two Iraqi officials told AFP President Donald Trump warned that the United States would block the country's account at the Federal Reserve bank in NY, a step that would devastate the oil producer's economy.
The destruction didn't end there: heavy concrete blast walls were knocked over and shipping containers were smashed, their contents of bicycles, chairs and other furniture also destroyed.
The air base is one of the largest and biggest in the country but lacks sufficient surface-to-air defenses, as the U.S. did not build such structures on the base.
A spokesman for the US -led coalition in Iraq said no Americans were present at the base when the attack was launched.
"They won't say so publicly".
Lt Col Coleman recalled that by 10pm all staff in her care had taken cover.
The assault, soldiers said, went on for two hours.
"You see a white light like a shooting star and then a few seconds later it lands and explodes".
One missile landed on the tarmac of a parking and servicing area for Blackhawk helicopters helping to ferry equipment in the fight against militant Islamic State (IS) insurgents.
According to International Assesment and Strategy Centre, a US-based think tank, the S-300s are one of the most capable air defence systems now in service.
There was no immediate claim of responsibility for Sunday's rocket attacks, in which the Iraqi military said eight missiles wounded two Iraqi officers and two airmen. Military sources identified the wounded as Iraqi soldiers.
