Majid Mousavi, IRGC Air and Space Force commander, declared that Iran will no longer launch missiles with warheads under one tonne. All future strikes will carry 1,000kg-plus warheads, with increased "intensity and frequency" of fire. Iran followed the announcement with its first missile wave under Mojtaba Khamenei's authority, claiming launches of one-tonne warheads at Ben Gurion Airport.
The shift from saturation to concentration is Iran's answer to CENTCOM's claimed 90% reduction in ballistic missile strikes from Day 1. Fewer launches, more destructive energy per strike. The doctrine change reflects both strategic adaptation and material constraint: Israeli strikes on 50 ammunition storage shelters across Iran on the same day, combined with ten days of sustained bombing of launch infrastructure, have depleted lighter missile stockpiles. The 109 drones and 9 ballistic missiles Iran launched at the UAE on Friday alone demonstrated that dispersed capacity survived the destruction of Central Command — but lighter munitions are finite, and the burn rate has been extraordinary.
Heavier warheads present a different problem for Israel's layered air defences. Arrow-3 and David's Sling intercept at altitude, where trajectory prediction is most reliable. A 1,000kg warhead carries greater kinetic energy on terminal descent, narrowing the interception window for lower-tier systems and increasing damage if interception fails. Whether the shift translates to greater impact depends on a variable the announcement cannot address: inventory. Iran's Kheibarshekan and Emad missiles can carry payloads in this range, but the number of one-tonne warheads available is unknown outside Tehran's planning cells. If stocks are deep, the doctrine functions as escalation. If they are shallow, the announcement dresses a final expenditure as strategy.
The IRGC Aerospace Force headquarters and drone command centre in Tehran were struck by the IDF hours before the announcement. That Iran could declare a new warhead doctrine and execute its first launches under it on the same day means either the shift was pre-planned before the headquarters fell, or the IRGC's devolution to 31 autonomous provincial commands provides sufficient redundant command capacity to absorb the loss of central headquarters and escalate simultaneously. The IRGC's pledge of "complete obedience" to Mojtaba Khamenei came the day before; this doctrine is the first operational expression of that pledge.
