The Wall Street Journal, citing US intelligence officials, reported on 10 April that Iran has preserved roughly half its ballistic missile and attack-drone stockpile. Defence Secretary Pete Hegseth called the programme 'functionally destroyed' a fortnight earlier.

Key takeaway

Washington's spies believe Iran can still hurt things; Washington's ministers do not say so.

The Wall Street Journal, citing US intelligence officials, reported on 10 April that Tehran has preserved roughly half its ballistic missile and attack-drone stockpile and retains "thousands of ballistic missiles"⁠¹. Defence Secretary Pete Hegseth had told reporters in late March that Iran's missile and drone programmes were "functionally destroyed", and Benjamin Netanyahu said last month that Iran had "no ability" to rebuild.

More than half of Iran's missile launchers have been destroyed, damaged, or buried by US and Israeli strikes, the same officials say, but Tehran can still repair them or dig the buried ones out. US intelligence believes Iran can reconstitute significant strike capability on a timeline measured in months, not years. This is single-provenance US-intelligence reporting relayed through one American paper.

The assessment arrives in the same week Washington has issued zero formal Iran presidential instruments across the full war and during the diplomatic window opened at Islamabad. Every declaration of completion in this war has been followed within days by an intelligence assessment that quietly contradicts it: Trump's "nuclear objective attained", Hegseth's "functionally destroyed", Netanyahu's "no ability". The public claim shrinks; the private estimate catches up.

Deep Analysis

In plain English

Defence Secretary Hegseth said Iran's missiles were 'functionally destroyed'. Israel's Netanyahu said Iran had 'no ability to rebuild'. The US intelligence community — the same officials whose analysis underlies both those claims — now says Iran has kept roughly half its missiles. This does not mean the strikes failed entirely: more than half of Iran's launch platforms (the vehicles and fixed sites from which missiles are fired) have been damaged or destroyed. But the missiles themselves, buried in dispersed underground sites, survived in much larger numbers than the public statements suggested.

Deep Analysis

Root Causes

Iran's missile survivability reflects two design choices made over 15 years of sanctions pressure. The IRGC Aerospace Force built geographically-dispersed underground storage — the buried launchers US officials acknowledge can be excavated — specifically anticipating an air campaign that could not sustain ground-level destruction of hardened sites.

The second factor is the Decentralised Mosaic Defence doctrine itself: by devolving launch authority to autonomous provincial units, Iran reduced the command-and-control concentration that would make a decapitation strike operationally effective. A 50% launcher loss with dispersed warhead survival is a designed outcome, not a failure.

Source Landscape

Israel

Primary parallel: In 2003, Colin Powell's UN presentation assessed Iraqi WMD capabilities as active and substantial; post-invasion inspections found nothing. The inverse pattern applies here: official declarations ('functionally destroyed', 'no ability to rebuild') are now being contradicted by the same intelligence community that produced them, within weeks of the original claims.

Counter-parallel: After the 2011 Libya intervention, Western assessments of Gaddafi's retained capability were broadly accurate — but the relevant precedent is the post-2014 period, when 'degraded' armed factions reconstituted faster than projected because dispersal protected assets that airstrikes could not reach.

Consensus view: RUSI's 'Command of the Reload' report (April 2026) and the Stimson Center both assessed that Iran's Decentralised Mosaic Defence doctrine — devolving launch authority to 31 autonomous provincial units — means targeting missile infrastructure does not map linearly onto capability degradation. Dispersed and buried stocks are survivable assets.

Counter-view: The Foundation for Defense of Democracies argues that intact stockpiles are strategically irrelevant if launcher attrition exceeds 50% — Iran cannot fire missiles it cannot mount, and the launcher rebuilding timeline is the binding constraint, not the warhead count.

Key tension: Whether Iran's residual capability is a deterrent that constrains US and Israeli military options, or a paper threat that cannot be operationalised within the ceasefire window.

This Event

Half of Iran's missiles survive, WSJ reports

The rhetoric-versus-reality gap is becoming the war's most consistent pattern, and every future strike calculus must assume Iranian retaliation capability rather than a degraded one.

Different Perspectives

United States (Joint Maritime Information Center)

The JMIC, the US-led naval reporting cell, rated the Hormuz threat "severe" in its 25 October advisory, as reported by gCaptain, and warned of possible renewed mining. Eight days earlier it found no substantiation for the Guards' mine claims, while US-facilitated transits ran at about 34 a day.

United Kingdom (CPS and Counter Terrorism Policing)

The CPS charged two men under the National Security Act 2023 over the RAF Fairford incident, and Counter Terrorism Policing said it believes the foreign intelligence service involved is Iran's, LBC reported. The case now runs through the courts; both men are charged, not convicted.

Aden and Yemen's recognised government

The Houthis told people to leave Aden airport, in the government-held south, before a missile fell there on 28 October, AFP reported, and police reported a second attack that afternoon. The fight between Riyadh and the Houthis is landing on the south's main civilian airport.

Qatar (mediators)

Qatar-led mediators put new terms to Iran this week, which an Iranian official called "ideas, not a proposal". Riyadh framed the Tehran meeting as support for Qatari and Pakistani mediation, keeping Doha at the centre of the indirect channel.

Korea Shipowners' Association

The association said the ships Iran listed were sub-chartered to an overseas oil company, not owned by Sinokor, carried no South Korean crew, and that Sinokor was unaware of the warning. South Korea's shipowners are contesting whose vessels the notice covers before it takes effect.

Kuwait (foreign ministry)

Kuwait summoned Iran's ambassador, Mohammad Toutounji, and handed him a protest note over the embassy's denial that its citizen took part in the alleged plot against Interior Minister Fahad Al-Yousef. Kuwait is answering through its courts and a diplomatic protest, citing international law and the UN Charter.
