Warheads
Conventional warhead types deployed on Iranian missiles and drones — from unitary blast warheads to cluster submunitions designed to maximise area damage.
A missile's destructive power is not determined by speed or range alone. Two missiles arriving at the same target at the same speed can produce entirely different damage footprints depending on the warhead fitted. Iran has invested heavily in diversifying warhead types across its arsenal, allowing commanders to select munitions matched to specific target sets: hardened bunkers, airfields, radar sites, troop concentrations, or civilian infrastructure.
Four primary warhead categories are documented in Iran's conventional arsenal. The same airframe can sometimes be fitted with different warhead types depending on the mission.
| Warhead Type | Description | Carried By | Damage Pattern |
|---|---|---|---|
|
Unitary HE
High Explosive | Single large explosive charge; primary effects are blast overpressure and fragmentation from the casing. | Emad, Ghadr, Sejjil, Kheibar Shekan, Khorramshahr-4, Paveh, Hoveyzeh | Single crater; blast radius 50–200 m depending on warhead mass; lethal fragmentation out to ~2× blast radius |
|
Cluster / Submunition
Area Effect | Warhead dispenser opens mid-flight or at altitude, releasing dozens to hundreds of smaller bomblets. Each bomblet creates its own blast and fragmentation zone. | Khorramshahr-4 (claimed); potentially fitted to other MRBMs on selected missions | Wide area coverage 500 m–1 km+ diameter; effective against dispersed targets, airfields, vehicle parks, radar arrays |
|
Blast-Fragmentation
Small HE | Small HE charge with pre-formed metal fragments embedded in or surrounding the warhead body. Designed for soft target lethality at low cost. | Shahed-136, Shahed-131, Shahed-238 | Limited blast radius ~10–20 m; fragmentation lethal to ~50 m; designed for soft targets and light structures |
|
Penetrator
Hard Target | Hardened steel or tungsten nose section designed to pierce reinforced concrete or earth-and-rock overhead cover before the main charge detonates inside the structure. | Potentially Fattah-1, Kheibar Shekan variants; assessed for use against hardened military facilities | Deep penetration into bunkers and hardened facilities; reduced external blast radius but targeted internal destruction |

Cluster munitions (also called submunition warheads) are particularly significant in the Iranian arsenal because they transform a single missile impact into an area-effect weapon, multiplying the damage footprint by an order of magnitude.
How They Work
- The missile's warhead section contains a dispenser loaded with dozens to hundreds of submunitions (bomblets)
- At a pre-programmed altitude or time-of-flight trigger, the dispenser opens and the submunitions are released into a ballistic spread pattern
- Submunitions disperse over an area of several hundred metres to several kilometres in diameter, depending on release altitude and warhead design
- Each submunition detonates individually on impact or via a proximity fuze, creating its own blast and fragmentation zone
- Some submunition designs include an anti-armour shaped charge in addition to blast-fragmentation effects
Why They Matter
- A single cluster-equipped Khorramshahr-4 could disperse submunitions across an area equivalent to 10–15 football pitches
- Effective against: airfields (cratering runways), military bases (disabling vehicles and equipment), troop concentrations, air defence radar arrays
- Harder for missile defence to fully neutralise — even a partially intercepted missile may release some submunitions before destruction
- Create a persistent post-strike threat from unexploded ordnance (UXO), which can render target areas unusable for days or weeks
- Force defenders to clear large areas before operations can resume, multiplying the operational impact beyond the initial strike

Legal Status
More than 100 nations have signed the Convention on Cluster Munitions (2008), which bans the use, production, transfer, and stockpiling of cluster munitions. Iran is Not a Signatory to this convention. Iran is therefore not legally bound by its prohibitions under international treaty law, although use of cluster munitions against civilian populations may still constitute a violation of customary international humanitarian law.
Warhead mass is the single most direct measure of destructive potential for unitary weapons. Bars are scaled to the Khorramshahr-4's estimated 1,500 kg warhead mass = 100%. A US Mk 82 general-purpose bomb (227 kg) is shown as a reference line.
Bars scaled to Khorramshahr-4 warhead mass (1,500 kg = 100%). Red = ballistic missiles, blue = cruise missiles, amber = drones, purple = hypersonic, gray = reference. Gray vertical line marks the Mk 82 bomb (227 kg) for orientation. Warhead mass figures are best-available open-source estimates and carry uncertainty.
Warhead mass equivalents — Mk 82 reference
Ratios are based on warhead mass only. Actual destructive effect also depends on fuzing, detonation altitude, target hardness, and whether warhead mass is pure explosive or includes casing. A missile arriving at Mach 9+ also imparts significant kinetic energy on top of explosive yield.
Iran has publicly claimed that the Khorramshahr-4 (Kheibar) can carry multiple warheads — a capability that, if genuine, would represent a significant escalation in the missile's threat profile.
MIRV (Multiple Independently-targetable Re-entry Vehicle) refers to a missile that carries several warheads, each of which can be guided to a different target after separation from the main bus. Iran has claimed this capability for the Khorramshahr-4, and state media has shown imagery of what appears to be a multi-warhead re-entry vehicle.
If true, a single Khorramshahr-4 launch could engage multiple separate aim points simultaneously, forcing missile defence systems to track and intercept multiple inbound objects from a single launch event.
Even a basic MRV (Multiple Re-entry Vehicle, without independent targeting) would complicate interception significantly: defenders would need to engage each re-entry vehicle separately, multiplying interceptor expenditure per missile fired.
Western intelligence and open-source assessments are divided on whether Iran has operationally deployed a true MIRV capability. The most conservative view is that Iran may have demonstrated a proof-of-concept but may not yet have an operationally reliable, accurate system. The most pessimistic view holds that limited MIRV capability exists and was used during True Promise operations.
