The rockets landed on the outside fence of the base, the Iraqi military said.
Initial investigations showed attack aimed to strike Balad air base, north of Baghdad, but the rockets fell short and hit the village of al-Bu Asi just to the southeast, the security officials said.
The last attack on Balad air base was on March 15, when at least five rockets hit the base.
No group immediately claimed the attack, but armed groups that some Iraqi officials have said are backed by Iran have claimed similar incidents in the past.
