SeaHive-5
swarm-strike at sea.
A fully autonomous unmanned surface vessel engineered for long-range maritime strike — deploys a swarm of FPV drones and a persistent relay UAV from a single forward platform.
Who we are
A defense studio for unmanned naval systems.
Depthon Systems develops autonomous surface and underwater platforms for military and special-operations users — from hull and autonomy stack to payload integration and field deployment.
Capabilities
From concept to combat-ready.
USV platform
Long-range autonomous surface vessel with modular hex-bay deck.
FPV swarm strike
Configurable swarm of strike drones launched from the deck mid-mission.
Autonomy stack
GNSS + INS hybrid guidance, anti-jam logic, encrypted mesh C2.
Mission integration
Payload integration, training and field support for end users.
Technology
Engineered for contested waters.
- Anti-jam navigation
GNSS + INS hybrid guidance with anti-jam waypoint logic for GNSS-denied transit.
- Encrypted mesh C2
Mesh-capable datalink keeps the swarm and relay UAV under positive control beyond the horizon.
- Low radar signature
Composite hull with low radar cross-section for covert forward deployment.
- Modular hex-bay deck
Reconfigurable launch cells host strike, relay or sensor payloads per mission.
Capability set
Six pillars of the SeaHive-5.
Swarm strike launch
Up to five FPV strike drones and one relay UAV launched from the hex-bay deck.
Autonomous navigation
Beyond-horizon transit and station-keeping with no operator in the loop.
Anti-jam guidance
Hybrid GNSS / inertial navigation with anti-jam waypoint logic.
Low radar signature
Composite hull and low-profile silhouette for covert forward deployment.
Encrypted datalink
Mesh-capable, encrypted C2 link across vessel, relay and strike drones.
Seakeeping
Operational up to Sea State 5; survivable through Sea State 4 transit.
SeaHive-5 — autonomous strike USV with FPV swarm.
SeaHive-5 is a fully autonomous unmanned surface vessel engineered for long-range maritime strike operations. Its modular hex-bay deck deploys a configurable swarm of up to five FPV strike drones and one persistent relay UAV, enabling beyond-horizon engagement at ranges up to 300 nautical miles from a single forward-deployed platform.

From the drawing board.
Autonomy is the new firepower.
We embed autonomy at every layer — hull, navigation, swarm release and on-board perception — so SeaHive-5 can transit, hold station and release effects in GNSS-denied, contested environments.
