Rylan Hamilton and Austin Gray are co-founders of Blue Water Autonomy, a venture-backed defense tech startup designing and building the next generation of autonomous ships for the U.S. Navy and beyond.

Hamilton began his career as a Surface Warfare Officer in the Navy before moving into robotics. He joined Kiva Systems (later Amazon Robotics), where he scaled warehouse automation from thousands to tens of thousands of robots, and went on to co-found a robotics company acquired by Shopify for hundreds of millions. Gray started as a Navy intelligence officer, later helped launch defense tech initiatives at MIT, and spent time in a Ukrainian drone factory before turning to maritime autonomy. Together, they founded Blue Water Autonomy to tackle one of America’s most pressing challenges: revitalizing shipbuilding and expanding the Navy’s fleet with cost-effective, autonomous vessels.

In this episode of Defense Tech Underground, we sit down with Rylan and Austin to explore how autonomy at sea is reshaping the future of maritime power. We cover:

This conversation highlights how two veterans turned robotics entrepreneurs are bringing private capital, Silicon Valley speed, and deep Navy experience to one of the hardest problems in defense: building ships faster, smarter, and more resilient.
