    015: Rylan Hamilton & Austin Gray – Blue Water Autonomy: Building the Navy’s Future Fleet

    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: Engineering autonomy – solving the hard problems of redundancy, endurance, and reliability in ocean-going ships without crews. The hybrid fleet vision – how unmanned vessels will complement destroyers, frigates, and carriers, carrying payloads without putting sailors at risk. Crawl, walk, run – why a phased approach to shipbuilding beats the Navy’s traditional “build once for 40 years” model. Dual-use opportunity – where autonomy at sea can extend to commercial sectors like tugs, ferries, and logistics, once regulatory barriers fall. Founder lessons – obsession, grit, and timing: why conviction matters, and what advice they’d give to future defense tech entrepreneurs. 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. This episode is hosted by Josh Pickering and Jeff Phaneuf.   Full Bios: Rylan Hamilton Rylan Hamilton is co-founder and CEO of Blue Water Autonomy. He served as a Surface Warfare Officer in the U.S. Navy before beginning a career in robotics at Kiva Systems, which was later acquired by Amazon to become Amazon Robotics. He co-founded 6 River Systems, a warehouse robotics company that scaled globally before being acquired by Shopify. Hamilton brings two decades of experience at the intersection of defense, robotics, and entrepreneurship to leading Blue Water Autonomy. Austin Gray Austin Gray is co-founder and President of Blue Water Autonomy. He began his career as a Navy intelligence officer, serving on aircraft carriers in the Middle East and South China Sea before earning his MBA at Harvard Business School. He co-founded and helped run the MIT–Harvard Defense Tech Initiative and worked in Ukraine’s drone sector before turning his focus to maritime autonomy.

    014: John Clark & Chris Moran – Lockheed Martin: Innovation with Purpose

    John Clark is Senior Vice President of Technology and Strategic Innovation at Lockheed Martin Skunk Works, the legendary advanced development program behind the U-2, SR-71, F-117, and F-35. Over his 27-year career, including 25 inside Skunk Works, he has led some of the most important innovations in aerospace and defense. Chris Moran is Vice President and General Manager of Lockheed Martin Ventures, the corporate venture arm investing in breakthrough startups across AI, autonomy, advanced manufacturing, power, and propulsion to bring critical technologies into Lockheed’s programs. In this episode of Defense Tech Underground, we sit down with John and Chris to explore how a century-old prime contractor sustains a culture of innovation while working alongside a new generation of defense tech startups. We cover: Skunk Works culture and the 14 rules – why they still matter today, and how Clark applied them in leading programs from the F-22 to modern autonomy efforts. Innovation with purpose – Lockheed’s philosophy of tying new technology directly to warfighter needs, from AI-tuned radar to layered defense systems. Lockheed Ventures – Moran’s view on “gaps and hedges,” the fund’s 90+ portfolio companies, and how primes and startups can create one-plus-one-equals-three outcomes. AI and open architectures – where generative AI, advanced autonomy, and spectrum convergence are reshaping design, manufacturing, and operations. The prime paradox – responding to critics who call primes slow and risk-averse, and why, in Clark’s words, “don’t believe the hype—innovation happens every day inside Lockheed.” This conversation highlights how the largest defense contractor in the world is leaning into venture capital, software-hardware convergence, and cultural lessons from Skunk Works to keep pace with evolving threats while partnering with startups. This episode is hosted by Josh Pickering and Andrew Couillard. Full Bios: John Clark John Clark is Senior Vice President, Technology and Strategic Innovation at Lockheed Martin, where he leads enterprise technology strategy and investment, including companywide digital and AI initiatives. He moved into the role after serving as Vice President and General Manager of Skunk Works from 2022 to early 2025. Earlier, Clark was Vice President of Engineering and Technology for Aeronautics and previously Vice President for ISR and Unmanned Systems at Skunk Works, roles that spanned portfolio leadership, systems integration, and multi-domain operations. Chris Moran Chris Moran is Executive Director and General Manager of Lockheed Martin Ventures, the company’s venture capital arm. He joined in 2016 after three decades in Silicon Valley, including senior executive roles at Applied Materials and eight years running Applied Ventures. He holds BS and MS degrees in mechanical engineering from MIT. Moran’s team invests across priority areas aligned with Lockheed Martin’s strategy. The fund size was doubled to $400M in 2022, and LM Ventures partners closely with internal engineering groups on adoption. He also engages with Stanford’s Hacking for Defense program.
