What we're building.

Liminal Stratum is developing a new class of unmanned weapon system engineered for the air-sea boundary. One platform. One unbroken mission thread. No domain handoff required.

Autonomous Cross-Domain Vehicle

The Autonomous Cross-Domain Vehicle is an unmanned weapon platform built to operate across the air-sea boundary in a single continuous mission. It launches aerially, crosses the water surface, and engages underwater — without requiring a separate platform or a handoff between systems at any point in the engagement.

Conventional systems treat the water surface as an endpoint. The Autonomous Cross-Domain Vehicle treats it as a waypoint.

The catalog is expanding. The Autonomous Cross-Domain Vehicle is the first system in a broader family of trans-medium platforms. Additional systems are in early-stage research and will be listed as development matures.
