Mousavi added that the “wavelength” and intensity of missile launches will increase, with attacks broadening in scope, according to Iran International.
Iran will only launch missiles with warheads weighing over one ton, Islamic Revolutionary Guard Corps (IRGC) Aerospace Force commander Majid Mousavi said on Monday, according to Iranian opposition outlet Iran International.
To put this in perspective: At the outset of the current conflict with Iran, a missile weighing hundreds of kilograms but less than one ton completely destroyed a building in Tel Aviv.
Mousavi added that the “wavelength” and intensity of missile launches will increase, with attacks broadening in scope, according to Iran International.
Iran, though weakened by US and Israeli strikes, still has a powerful arsenal at its disposal, according to a Wall Street Journal report citing Martin Sampson, former UK defense adviser and leading Middle East military analyst.
These weapons include cruise missiles, cyber warfare, and mines, according to the WSJ, which quoted Sampson as saying that Iran “potentially has the ability to escalate much more broadly” with its current reserve.

Use of cluster munitions in Operation Roaring Lion, and in previous war with Iran
Iran has begun using cluster munitions in recent strikes, resulting in the killing and wounding of Israeli civilians. Cluster munitions are known to be highly destructive; Iran also used them against Israel in the 12-Day War in the summer of 2025.
According to an initial investigation, conducted during the 12-Day War following suspected use of cluster munitions, the missile split into several smaller bombs approximately seven kilometers above the ground, creating an eight-kilometer impact radius when they fell.
Each of the smaller bombs carried around two kilograms of explosives.
Mousavi did not clarify whether or not the heavier warheads would also contain cluster bombs, which can be made in a variety of weight ranges.
Despite Saturday spike in missile sirens, IDF affirms 75% of Iranian missile launchers destroyed
Although there was a spike in Iranian ballistic missile threat sirens on Saturday, sending millions of Israelis into their safe rooms and bomb shelters throughout the day, the IDF said that it had destroyed 75% of Iran’s missile launchers.
The 75% figure is a jump from 65% two days ago.
At the same time, IDF sources have not expressed any certainty about fully stopping Iranian missile fire in the near future.
