Quoting the Defence Minister Ali Shamkhani, the Tehran Times on Sunday said the rocket would be tested to keep the country prepared for an attack.
"A society which does not prepare itself for threats will meet the same fate as Saddam Hussein," Shamkhani was quoted by the daily as saying.
Iran has several times warned of a probable attack by the US or Israel and Shamkhani said Iran should be prepared for the worst-case scenario.
The minister rejected Israeli accusations that its missiles were a threat to Europe, saying Iran's military strategy was not a threat to any country and aimed solely at defensive purposes.
It tested the missile in June last year when it was delivered to the armed forces. The medium-range ballistic missile has a range of 1300km, meaning it could reach Israel.
Testing missiles is its legitimate right, Iran says.
