Launched DoD Replicator autonomous systems program
Kathleen Hicks
Profile
Kathleen Hicks served as the 35th US Deputy Secretary of Defense from 2021 to 2025 — the first Senate-confirmed woman to hold the Pentagon’s number-two job. For developers watching AI move from labs into the physical world, she matters because she pulled the lever that turned the Pentagon from a slow, exquisite-platform buyer into something trying to act like a startup. That lever has a name: Replicator.
Announced in August 2023, Replicator is Hicks’s explicit answer to China’s manufacturing mass. The pitch: field “multiple thousands” of attritable, all-domain autonomous systems inside 18–24 months — cheap drones in the air, on the water, under it, on the ground — produced fast enough that losing them is a design feature, not a disaster. The Defense Innovation Unit runs execution; about $1B was committed across FY24–25. It’s the first time the Pentagon publicly bet the strategy on autonomy-at-scale instead of a handful of exquisite platforms, and it dragged companies like Anduril (see Palmer Luckey), Shield AI (see Brandon Tseng), and Skydio from outsiders to primes-in-waiting.
Hicks isn’t a Silicon Valley outsider airdropped in. She’s a career defense policy wonk — MIT PhD, CSIS senior fellow, Principal Deputy Under Secretary of Defense for Policy under Obama — who spent decades inside the machine before trying to retool it. That matters because Replicator’s hardest problem was never the tech; it was the acquisitions system. She pushed through the Political Declaration on Responsible Military Use of AI (60+ signatories) and tried to wire “human judgment over use of force” into autonomous-weapons doctrine before the systems arrived.
The results are genuinely mixed. By the August 2025 target, Congress and CSIS reported “hundreds,” not thousands, of systems delivered. Critics — including Mike Gallagher while in Congress — argued Replicator was opaque, rebadged existing programs, and moved slower than the rhetoric. After leaving DoD in January 2025, Hicks returned to CSIS. The initiative itself lives on, rebranded as the Defense Autonomous Warfare Group (DAWG), now looking at larger uncrewed systems. Whatever you think of the execution, she changed the Pentagon’s default: autonomy is now the strategy, not a side project.

Replicator delivery gap. The program promised “multiple thousands” of autonomous systems by August 2025. Congressional Research Service reporting and defense press coverage put the actual number at hundreds. Hicks’s defenders note the program intentionally relied on existing authorities and money rather than waiting for new appropriations; critics argue that accounting trick is why results came slowly.
Transparency and oversight. Lawmakers — notably former Rep. Mike Gallagher — repeatedly complained Congress and industry couldn’t tell what Replicator actually was, what was being bought, or how success would be measured. Hicks pointed to ~40 classified Hill briefings as evidence of engagement; critics called the public story thin.
Autonomous weapons ethics. As the official most publicly associated with fielding armed autonomous systems at scale, Hicks has drawn criticism from arms-control groups arguing the “human judgment” language in DoD Directive 3000.09 is too elastic. Her counter: the US is writing the rulebook other militaries will follow, and opting out cedes that to adversaries.
