Technology: US-based Anduril launches AI-powered Seabed Sentry to transform subsea defense operations.

In a bold leap forward for autonomous maritime surveillance, Anduril Industries, a defense technology company based in the United States, has announced the expansion of its undersea capabilities with the launch of Seabed Sentry, a modular, AI-powered network of deep-sea sensor nodes designed for persistent, real-time monitoring of subsea environments. This cutting-edge system aims to revolutionize undersea awareness and communications for both military and commercial users by overcoming the longstanding limitations of current seabed monitoring technologies.

While surface and aerial platforms benefit from clear lines of sight and reliable communication links, the subsea domain remains a challenging frontier due to its vastness and opacity. Conventional subsea sensing systems often operate slowly and in isolation, unable to relay critical data in real time without significant infrastructure investments. Seabed Sentry addresses this challenge with a cable-less, AI-enabled solution that delivers unprecedented situational awareness and subsea connectivity at a fraction of the cost of legacy systems.

Built with superior endurance and adaptability, Seabed Sentry is rated for depths exceeding 500 meters and can operate autonomously for extended durations—ranging from months to even years. Its payload capacity of over 0.5 m³ supports a wide array of mission-specific sensor packages. The system is modular and reusable, reducing lifecycle costs by enabling recovery, cleaning, recharging, and redeployment.

Each Seabed Sentry node functions as an intelligent edge processor, using Anduril’s proprietary Lattice AI software platform to sense, process, and transmit critical data in real time. These mobile nodes can be deployed by Autonomous Underwater Vehicles (AUVs) to form dynamic defense grids that are highly responsive and scalable.

Designed with open systems architecture, Seabed Sentry supports seamless integration of both Anduril-native and third-party payloads. It can be rapidly customized for a variety of missions, including seabed surveys and marine life pattern monitoring, port and critical infrastructure protection, anti-submarine warfare (ASW) and anti-surface warfare (ASuW), underwater domain awareness, and maritime kill chain support. A key enabler of this capability is Ultra Maritime’s Sea Spear, integrated into Seabed Sentry to deliver long-range sensing capabilities in remote and contested underwater environments.

Seabed Sentry is part of a larger ecosystem that includes Anduril’s Dive family of large and extra-large autonomous submarines. Together, they create an interconnected network that enables operators to sense, analyze, and act across the undersea battlespace with unprecedented speed and efficiency.

As demand grows for scalable undersea surveillance solutions, Anduril has ramped up investments in production infrastructure to ensure timely delivery and deployment of Seabed Sentry units. These facilities will enable mass production, supporting urgent customer needs without the delays associated with bespoke manufacturing.

With the global strategic landscape shifting and maritime domains becoming increasingly contested, control over the seafloor—and the ability to monitor and secure key underwater infrastructure—has emerged as a critical priority. Seabed Sentry represents a fundamental shift in how nations can achieve persistent undersea dominance with smart, scalable, and cost-effective systems.

Through its innovative design and integration with broader autonomous systems, Seabed Sentry solidifies Anduril’s position at the forefront of next-generation maritime defense technology. As the race for undersea superiority intensifies, Seabed Sentry offers a robust and forward-looking solution for modern navies and commercial operators alike.
