Iran's Ballistic Missile Arsenal

There's a photograph of an Iranian Scud missile from the war with Iraq. Painted on the side, in Persian and Arabic: "Death to America, Death to the Soviet Union, Death to Israel, Death to Saddam."

All four at once. That's... ambitious.

That missile wasn't even Iranian. Tehran bought its first thirty Scuds from Libya. They had no program. They had a shopping list.

So how do you get from buying thirty missiles off Gaddafi to whatever it is they have now?

That's the question. And here's the one I want you to hold onto: the United States Department of War said in September that America destroyed about ninety percent of Iran's industrial base for drones, ballistic missiles and naval capability. Ninety percent. So why, as of this month, are Israeli officials saying Iran's launcher force is nearly back to pre-war levels?

Nearly back? In months?

We'll get there. Start with the lineage. The Revolutionary Guard took those Libyan Scuds apart and reverse-engineered the components. That becomes the Shahab-one and Shahab-two — Scud-B and Scud-C lineage, liquid fuel, three hundred to five hundred kilometres.

And accurate to...?

Iran Watch puts the Shahab-one at roughly five hundred metres, the Shahab-two at seven hundred.

Seven hundred metres. So you're not hitting a building. You're hitting a neighbourhood.

Right, and that's the whole story in one number. The London Dialogue report from July this year puts it beautifully: a missile that lands within five hundred metres of its aim point is a weapon against cities. A missile that lands within thirty metres is a weapon against aircraft shelters, command bunkers, radars and runways.

Same rocket, completely different war.

And they call that shift the single most consequential change in Iranian capability of the past fifteen years. And it isn't a propulsion problem. It's guidance and control. Software, basically.

Okay, so where does the long-range stuff come from? Because Scuds don't reach Israel.

The Shahab-three. Thirteen hundred kilometres, liquid-fuelled. The US National Air and Space Intelligence Center says it's based on North Korea's No-Dong. Iranian officials dispute that. China supplied a whole missile system — the Tondar-sixty-nine — plus gyroscopes. Russia gave technical assistance and raw materials in the nineteen nineties.

So three countries helped build it.

And the early Shahab-three had a circular error probable of about three kilometres.

Three KILOMETRES? That's not a weapon, that's a weather event.

Which is why the interesting family is the other one. Solid fuel. The Fateh-one-ten, three hundred kilometres, about a hundred metres accuracy. Then Fateh-three-thirteen and Zolfaghar — Iran Watch lists both at ten to thirty metres.

From three kilometres to ten metres. Hang on, is that verified, or is that Tehran's brochure?

Good instinct, and the London Dialogue report flags exactly that. An accuracy figure might come from an Iranian claim, from outside modelling, from reading test footage, or from satellite imagery of an impact — and those are not equivalent in reliability. They refuse to publish numbers they can't source.

What about the hypersonic ones? The Fattah. That was everywhere in 2023.

The London Dialogue calls the marketed hypersonic performance a manufacturer's claim, not an assessed capability. Fabian Hinz of the IISS says the hypersonic label is dubious and obscures more than it illuminates.

Why? It does go that fast, doesn't it?

Everything does. Any missile with a fourteen-hundred-kilometre range comes down at three to four kilometres a second — Mach ten to thirteen. That's true of the Shahab-three, which they've had for twenty-five years. A property shared by every member of a category tells you nothing.

So "hypersonic" is just... physics with marketing.

The real innovation is the manoeuvring re-entry vehicle. The Fattah-one has a small rocket motor inside the warhead so it can jink on the way down. That's genuinely hard to intercept. And the Fattah-two? Iran Watch lists it as displayed. Not launched.

So the sanctions. Thirty years of them. What did they actually stop?

Not much, because the program was never really an import business after the eighties. It was reverse-engineering plus a procurement network — China remains a key jurisdiction for dual-use goods, and the US Treasury was still sanctioning transnational missile procurement networks as recently as November twenty twenty-five.

And now the loop. Ninety percent destroyed, but back to full strength?

Careful — two different things. Launchers, yes: Israel's Channel Sixteen reported on the fifteenth of October that the launcher force is back to at least four hundred, against four hundred and twenty before the war. Factories, no. The Foreign Policy Research Institute surveyed Parchin, Khojir and Shahroud by satellite on the fourteenth of October. Solid propellant production at both sites: not operational. Still strewn with rubble.

So they're not making new ones. They're assembling what was already in the warehouse.

The Wall Street Journal reported on the twenty-third that Iran has resumed limited production underground from stockpiled components. FPRI partly disagrees — they see no sign of underground assembly at Khojir specifically. And last Sunday, Iran's parliament made Mehrdad Akhlaghi defence minister. One of the founders of the missile program.

That's not a subtle signal.

Before the war: about twenty-five hundred ballistic missiles. Today, analysts tell the Journal the stockpile is somewhere between hundreds and thousands.

That range is doing a lot of work.

It's the honest answer. Nobody outside knows. What we do know is that a country that started by buying thirty missiles from Libya has spent forty years making itself impossible to disarm from the air.

Because the knowledge doesn't live in the buildings.

You can flatten a casting pit. You can't bomb a blueprint.
