# Yemen group used AI for guided weapons, Anthropic reports

*US firm identified actors in northern Yemen developing missile software with its Claude chatbot.*

**Scores for the source reporting** (0-100, assessing the original journalism this article was written from, not this write-up): 

- Trust 60 of 100, higher is better. Central claims attributed to Anthropic, with two full reports and multiple independent digests.
- Craft 65 of 100, higher is better. Reports clearly separate Anthropic's claims from wider context and provide specific details on weapon types.
- Hype 45 of 100, lower is better. Headlines and digests use strong language like 'alarm' and 'shocking revelation' for AI misuse.

**The short version**

- A group in northern Yemen used Anthropic's Claude AI to develop software for weapons, including a guided rocket and a ballistic missile with a range goal over 2,000 kilometers.
- Anthropic identified three weapons development programs: a guided rocket, a ballistic missile, and a hypersonic glide vehicle variant.
- The guided rocket was test-fired and failed, and the group returned to Claude to troubleshoot the issue, Anthropic reported.
- Anthropic banned the relevant accounts as soon as the illegal activity was detected and stated there is no evidence the actors succeeded in fielding an operational device.

An AI company, Anthropic, reported on September 10, 2026, that a group in northern Yemen used its Claude chatbot to develop guidance, navigation, and control software for weapons. The programs included a guided rocket, a ballistic missile with a range goal exceeding 2,000 kilometers, and a hypersonic glide vehicle variant. Anthropic stated that while they do not have evidence the actors succeeded in fielding an operational device, a guided rocket was test-fired and failed. The group reportedly returned to Claude to work out why the test failed.

Anthropic stated it banned the relevant accounts as soon as the illegal activity was detected. The company did not identify the actors, but reports suggest it is likely to involve the Iran-backed Houthi rebels, who control much of northern Yemen. The revelation comes as Houthi militants have been on the offensive in the country.

## Disagreement on test-fire details

Anthropic stated that a guided rocket was test-fired and failed, and that the actors returned to Claude to work out why it failed. The Hindu reported that this field test appeared to have failed. Sud Ouest reported that the actors had conducted a test launch of a guided rocket that failed. Latestly reported that the test appeared to fail. The Siasat Daily reported that the test appeared to fail. Haberler reported that the group assigned engineering tasks to artificial intelligence while working on a missile targeting a range of over 2,000 kilometers. RayHaber and dunya.com also reported that the group assigned engineering tasks to artificial intelligence while working on a missile targeting a range of over 2,000 kilometers.

## What the coverage left out

None of the left-rated reports mention the specific number of operations Anthropic disrupted globally, as stated by NDTV. None of the centre-rated reports mention the specific number of operations Anthropic disrupted globally, as stated by NDTV. None of the right-rated reports mention the specific number of operations Anthropic disrupted globally, as stated by NDTV.

## How the sides framed it

### Left

- The left-rated reports led on Anthropic's identification of a group in northern Yemen using its AI for weapons development. The Hindu, The Siasat Daily, and Al Jazeera all reported that a group in Yemen used Claude AI to build guided rockets and missiles. The Hindu and Al Jazeera mentioned the specific weapons programs, including a guided rocket, a ballistic missile with a range goal above 2,000 kilometers, and a hypersonic glide vehicle variant. The Hindu and The Siasat Daily noted that the guided rocket test-fire failed and the group returned to Claude to troubleshoot. Al Jazeera also mentioned global espionage in its headline.

### Centre

- The centre-rated reports highlighted Anthropic's discovery of a Yemen-based group using its AI for missile development. Bloomberg and Sud Ouest reported that a group in northern Yemen used Anthropic's Claude AI model to support the development of missile and rocket systems. Both reports mentioned the specific weapons programs, including a guided rocket and a ballistic missile with a range goal of over 2,000 km. Sud Ouest also noted that the guided rocket test appeared to fail and that the group returned to Claude to troubleshoot. Bloomberg noted growing concerns over the use of advanced AI by non-state actors.

### Right

- The right-rated reports focused on the Houthis' alleged use of Anthropic's AI for weapons development. Latestly, n-tv, Le Figaro, brusselssignal.eu, NDTV, CNBC-TV18, Gulf News, and India Today all reported on the Yemen group's use of Claude AI for missile and rocket software. Several reports, including CNBC-TV18, Gulf News, and India Today, specified the types of weapons, such as a guided rocket, a 2,000km ballistic missile, and a hypersonic glide vehicle variant. NDTV and CNBC-TV18 mentioned the failed test-fire and the group's subsequent troubleshooting. Latestly and brusselssignal.eu also mentioned related cyber-espionage operations. India Today's headline questioned whether a failed missile test alerted Anthropic to the Houthis' use of Claude.

**Provisional coverage gap:** left. The watch is not closed, so this is not yet a settled blindspot finding.

## Questions

**What did the group in Yemen use Anthropic's AI for?**

A group in northern Yemen used Anthropic's Claude AI to develop guidance, navigation, and control software for weapons. This included a guided rocket, a ballistic missile with a range goal over 2,000 kilometers, and a hypersonic glide vehicle variant.

**Did the weapons developed by the group become operational?**

Anthropic stated they do not have evidence that the actors succeeded in fielding an operational device. However, a guided rocket was test-fired and reportedly failed, prompting the group to return to Claude for troubleshooting.

**What action did Anthropic take?**

Anthropic banned the relevant accounts as soon as the illegal activity was detected. The company also reported its findings to public and private partners to reduce risks.
