President Donald Trump has ordered the Department of Defense (DoD) to revise Directive 3000.09, the policy that governs the deployment and testing of autonomous weapons, by early September. The directive, first issued in 2012 and last updated in 2023, sets protocols for guided missiles, drones and other systems and requires human operators to maintain control over lethal decisions.

The new order arrives as the Trump administration accelerates the use of artificial intelligence (AI) in large‑scale military operations, including recent deployments in Venezuela and the ongoing conflict in Iran. In January, Defense Secretary Pete Hegseth released a memorandum urging the Pentagon to become an “AI‑first” warfighting force across all components. The memorandum highlights the potential of AI to analyze vast data sets and assist troops in target identification.

Senators have expressed concern that the rapid adoption of AI could erode established safety protocols. Representative Ruben Gallego (D‑AZ) sent a letter to Hegseth last week requesting more transparency about the update. “Once you allow AI to take humans out of the kill chain decision‑making process, it becomes easier to kill people, which means it’s easier for you to go to war,” Gallego said.

A DoD spokesperson told reporters that humans will remain integral to deploying automated weapons. “The Department operates in full compliance with all U.S. laws and established Department policies, such as ensuring a human is always in the loop for critical operational decisions,” the official said. The spokesperson added that Directive 3000.09 already requires a human operator to oversee autonomous capabilities.

The Senate’s version of this year’s National Defense Authorization Act (NDAA) has not yet reached the floor but contains provisions that would forbid the military from using AI to decide whether a nuclear weapon should be deployed, to track constitutionally protected groups or individuals in the United States, or to plan attacks without “appropriate levels of human judgment.” The bill also seeks to enshrine in law some of the testing protocols in Directive 3000.09, including a requirement that the DoD report incidents involving autonomous weapons and share details of AI safety testing with Congress.

Senator Kirsten Gillibrand (D‑NY), who helped draft portions of the NDAA, said the legislation is needed because “lethal decisions require a conscience, not just an algorithm.” Senator Mike Rounds (R‑SD) noted that the pace of AI innovation makes it difficult for policy to keep up, adding that lawmakers must consider what adversaries are developing.

Michael Horowitz, a former senior Pentagon official who updated Directive 3000.09 in 2022, told reporters that the document was designed to be adaptable to new technologies. He said he trusts the military will prioritize reliability in the weapons it deploys but sees the current moment as an opportunity for Congress to reinforce the centrality of human judgment.

The debate is underscored by recent incidents. During the early days of the Iran conflict, U.S. forces mistakenly struck an all‑girls school that had been labeled a military facility, reportedly due to outdated data. Reports indicate that AI systems such as Anthropic’s Claude and OpenAI’s ChatGPT were used to analyze targets and that Claude “helped orchestrate 1,000 attacks in the first 24 hours of Operation Epic Fury.” The incident has fueled calls for tighter oversight.

The Trump administration’s push for AI adoption is part of a broader effort to modernize the Pentagon. The January memorandum, coupled with the new directive order, signals a shift toward integrating AI more deeply into planning and execution. However, the Senate’s proposed NDAA provisions suggest that lawmakers are wary of relinquishing too much control to autonomous systems.

As the DoD works to finalize the updated Directive 3000.09, the outcome will likely shape the balance between technological innovation and human oversight in U.S. military operations. The Senate’s NDAA, if passed, would codify several safeguards, but its status remains uncertain. The next few weeks will see the Pentagon, Congress, and defense officials negotiate the scope of AI’s role in future warfare.

The current situation remains fluid. The DoD has not yet released a timeline for the updated directive beyond the early‑September deadline. The Senate’s NDAA provisions are still under consideration, and no definitive legislative action has been taken. Observers will be watching for how the administration and Congress reconcile the promise of AI with the need for human judgment in lethal decision‑making.
