By bringing the expertise, technology, and business model of the 21st century’s most innovative companies to the defense industry, Anduril is changing how military systems are designed, built and sold. Anduril’s family of systems is powered by Lattice OS, an AI-powered operating system that turns thousands of data streams into a realtime, 3D command and control center. As the world enters an era of strategic competition, Anduril is committed to bringing cutting-edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years. ABOUT THE TEAM Anduril's Maritime Division is transforming American sea power to meet the defining national security challenges of our era and secure our future of maritime dominance. We are scaling at a historic pace, anchored by Arsenal-2, our new software-defined shipyard being built in Baltimore County, Maryland. It's part of a new $6.6 billion investment in America's submarine industrial base. Arsenal-2 is purpose-built to break long-standing industrial bottlenecks and scale production of critical components for the Navy's Virginia-class attack submarines to support fleet requirements. At the same time, it will build the industrial muscle to field our next-generation AUVs at scale. We aren't waiting for the new shipyard to be completed. The work on this transformation starts right now, with development inside our new 160,000 square foot Proto-Factory in Orange County, California, where the team is already laying the foundation. As the prototyping hub for Arsenal-2, this facility gives us a multi-year head start, proving out the advanced manufacturing methods, digital workflows, and quality systems that will scale across our broader shipyard network. In Anduril's Maritime Division, we are actively building America's next decisive advantage at sea—and this is the moment to join us.
