Over 580 Google Staff Urge Pichai to Block Military AI Use

More than 580 Google employees signed an open letter this week asking CEO Sundar Pichai to prevent the Pentagon from using Google’s artificial intelligence tools for military purposes. The group called for an immediate moratorium on deploying Google AI for defense applications.

The letter was signed by engineers across the company, including more than 18 senior staff members listed as principals, directors and vice presidents. Signatories asked for greater transparency about existing defense contracts and for a permanent ethics board that includes employee representation to review future military partnerships.

The document requests clear, binding rules to stop use of Google technology in weapons that operate without meaningful human control. It asks Google to explicitly bar its tools from being used for autonomous targeting, surveillance that enables lethal action and other applications that could directly harm people.

The employees highlighted concerns about Google Cloud services and the company’s machine‑learning platforms that could be integrated into weapons systems. “We want to see AI benefit humanity; not to see it being used in inhumane or extremely harmful ways,” the letter reads.

Signers cited Google’s 2018 withdrawal from a Pentagon program that analyzed drone footage as a precedent for refusing defense work on ethical grounds. The letter asks company leaders to publish details of current defense-related contracts and to set binding limits so technical teams and ethics reviewers can vet potential military uses before agreements are signed.

The staff action follows a recent dispute between the Defense Department and an AI startup that ended after the company declined to remove contractual limits on domestic surveillance and fully autonomous weapons use. The department later labeled that company a supply-chain risk, and the White House directed federal agencies to phase out some of its tools; a federal judge temporarily blocked the ban in March.

Pentagon officials have described autonomous weapons as central to future operations. Chairman of the Joint Chiefs of Staff General Dan Caine called autonomous weapons a “key and essential part of everything we do” going forward, a phrasing employees cited as a sign military adoption of AI could expand rapidly.

Google has not publicly detailed how it will respond to the open letter. The appeal adds to ongoing internal pressure at the company over past and potential defense work, with employees seeking commitments that any new protections be binding rather than advisory.
