Anduril Introduces Seabed Sentry Undersea Sensor Network

Anduril is expanding its maritime capabilities with Seabed Sentry, AI-enabled, mobile, undersea sensor nodes networked together for persistent monitoring and real time communication. Seabed Sentry uses artificial intelligence to provide highly accurate, persistent autonomous awareness on the seafloor for commercial and military customers.

Surface and air vehicles can operate with clear lines of sight and reliable connectivity, but the ocean is vast and opaque, leaving current autonomous subsea sensing and communications technology operating slowly in silos. We need a network for real-time data exchange to reliably transmit information into action. Seabed Sentry fills connectivity and perception gaps, enabling maritime awareness and kill chains in ways not currently possible without high expense. With superior endurance lasting months to years, a depth rating exceeding 500 meters, a payload capacity of over 0.5 m³, and a modular, reusable design, Seabed Sentry is built to surpass existing seabed surveillance solutions. It offers operators greater flexibility and capability in even the most challenging underwater environments.

Unlike fixed seafloor surveillance systems—which are expensive to place and maintain—Seabed Sentry is a network of ‘cable-less’ deep-sea nodes that sense, process, and communicate critical subsea information at the edge in real time. Powered by the Lattice AI software platform and able to support several payload variations, Seabed Sentry can be deployed by AUVs to form a defense grid, supporting the protection of key maritime regions and infrastructure. It has an open systems architecture for rapid integration of first or third-party sensors and payloads customized to the commercial or defense missions including seabed survey, marine pattern of life building, port security, critical infrastructure protection, anti-submarine warfare, and anti-surface warfare. Seabed Sentry exclusively leverages Ultra Maritime’s Sea Spear, enabling long range sensing capabilities in the most remote underwater environments.

Seabed Sentry is powered by Anduril’s Lattice software platform and integrates with our Dive family of large and extra-large autonomous submarines, contributing to a comprehensive, intelligent network of maritime capabilities that enables operators to quickly sense, analyze and then respond across the undersea battlespace, at a fraction of the cost of legacy options.

To meet growing demand, Anduril has made significant investments in several production facilities, which can soon begin producing Seabed Sentry, providing customers with the scalable, affordable technology it urgently needs. Seabed Sentry is designed for re-use: it can be deployed to the seabed, act, then be recovered, cleaned, recharged and re-used, ultimately driving down operational costs and avoiding potential manufacturing and production delays.

Anduril is building the future of maritime dominance with autonomous systems that are smart, scalable, and affordable. As strategic competition intensifies, control of the seafloor—and everything above it—requires a new set of undersea systems. Seabed Sentry is built to meet this challenge. Together with Anduril’s existing maritime products, it delivers a comprehensive, software-defined solution for both defense and commercial missions.
