Sentinel is our next-generation platform for sustained underwater presence — designed for missions that require continuous awareness, not just periodic visits. Built for the operational profiles where short-duration vehicles can't deliver the persistence missions demand.
Sentinel reflects a different design philosophy than conventional underwater platforms. Built around endurance, integration, modularity, and remote operation — the four characteristics that define the next generation of marine work.
Mission durations measured in weeks and months, not hours. Sentinel extends the operational tempo of marine work, reducing per-mission cost and enabling continuous data collection.
Built to operate alongside our broader platform family. Sentinel is part of an integrated fleet, designed for combined mission profiles rather than isolated deployments.
Modular payload configuration adapts the platform to the mission — different operations require different sensing, and Sentinel adapts rather than constrains.
Shore-based command-and-control infrastructure. Reduces logistical burden, enables faster response, and unlocks operating tempos that crewed assets cannot match.
Sentinel is in active development. We work with a small number of qualified partners on early deployment programs. If your mission profile demands persistent ocean presence, we'd like to talk.
