Google Signs Secret Pentagon AI Deal, Director Quits

What did Google agree to with the Pentagon?

Google signed a classified agreement with the US Department of Defence allowing the Pentagon to deploy its Gemini AI models on secret military networks for "any lawful government purpose," according to IBTimes UK reporting on the deal. Google told Business Insider the agreement was an amendment to an existing contract.

The contract bars use of AI for autonomous weapons or domestic mass surveillance without human oversight. It also states that Google cannot "control or veto lawful government operational decision-making."

Reuters reported that such deals with major AI labs were worth up to $200 million each.

Who resigned over the deal?

René Mayrhofer, director of security for the Android platform, resigned from Google in protest. He announced his decision in an internal letter titled "Google's management has lost its moral compass," which he later made public.

Mayrhofer wrote that staying at the company had become "inevitably impossible" after the Pentagon contract. He said Google had begun supporting initiatives incompatible with the values that brought him to the company in 2017, and criticized what he described as a lack of transparency from leadership on AI and defence decisions, as reported by Veja.

How did Google DeepMind employees respond?

More than 600 employees signed an open letter to CEO Sundar Pichai demanding he reject the deal before it was signed. Signatories came from Google DeepMind, Cloud, and other divisions. More than 20 directors, senior directors, and vice presidents signed openly.

The letter warned that classified military AI work could cause "irreparable damage to Google's reputation, business, and role in the world." It read: "The only way to guarantee that Google does not become associated with such harms is to reject any classified workloads."

Andreas Kirsch, a senior research scientist at Google DeepMind, posted publicly that he was "speechless" and "incredibly ashamed." He said he had woken to a "worst-case version" of what employees had feared, and wrote: "I do not understand how this is 'doing the right thing,' and I think this violates 'don't be evil' quite clearly on many levels."

Sofia Liguori, an AI research engineer at Google DeepMind in the UK, told Bloomberg that the company's response to worker concerns had been to encourage staff to trust leadership, but that it was "all left very broad."

How did Google get here?

In February 2025, Google removed language from its AI principles pledging to avoid building weapons or surveillance technologies. DeepMind CEO Demis Hassabis co-authored a blog post citing "a global competition taking place for AI leadership" as the reason. Human Rights Watch and Amnesty International both condemned the reversal.

By December 2025, the Pentagon had launched GenAI.mil, a platform powered by Google's Gemini chatbot available to all defence personnel. In March 2026, Google deployed Gemini AI agents to the Pentagon's three-million-strong workforce at the unclassified level.

How does this compare to Project Maven?

The backlash echoes Google's 2018 Project Maven crisis, when roughly 4,000 employees signed a petition and several resigned over a Pentagon contract that used AI to analyse drone footage. Google abandoned that project.

The letter's organizers referenced that history directly: "Maven is not over. Workers are going to continue organizing against the weaponization of Google's AI technology until the company draws clear, enforceable lines."

Where does the broader industry stand?

OpenAI signed its own classified Pentagon deal after revising its "no military use" policy. Anthropic, by contrast, was labelled a "supply chain risk" by the Department of Defence after refusing to loosen its guardrails on autonomous weapons and surveillance.

Big Tech firms are on track to spend roughly $600 billion on AI infrastructure in 2026. The Pentagon's own AI budget hit $13.4 billion for the fiscal year.

The letter's organizers said they would keep pushing back against what they called the weaponization of Google's AI technology.
