One stack. From handheld to fully autonomous.

Ci4 builds maritime autonomy in three layers: the platforms that go to sea, the sensing and communications technologies that let them operate in contested waters, and the AI software that ties data, mission and decision into one system.

01. Platforms

TANDAV

SYS / 03 · AUTONOMOUS

Autonomous Underwater Vehicle

An efficient, modular AUV for longer-range autonomous missions. Same vision and sonar stack, same swappable payload architecture, fully autonomous operation.

DEPTH RATING: 300 m
ARCHITECTURE: Modular Payload
AUTONOMY: NEXUS AI

ECHO

SYS / 02 · NO DIVER

Agile Underwater Drone

A compact, agile 6-DOF underwater vehicle that runs the same vision and sonar stack without a diver in the water. Swappable payloads and a sub-10-minute setup.

DEPTH RATING: 300 m
MOBILITY: 6-DOF
SETUP: < 10 min

AquaScan

SYS / 01 · DIVER-CARRIED

Underwater Multi-Modal Observation

A diver-carried sensing unit that sees, enhances and analyses underwater in real time. Fused sonar, 4K imaging and onboard edge inference put a maritime AI vision suite in the operator's hands.

DEPTH RATING: IP68 / 75 m
ENCLOSURE: AL6061-T6
SENSING: Sonar + 4K + Edge AI

SURGE

SYS / 04 · SURFACE

Autonomous Surface Vessel · 6–12 m

A full-stack autonomous surface vessel built to swarm, host UxV docks and operate beyond line of sight. The AI doesn't just observe here, it operates the platform.

ENDURANCE: 750+ nm
LENGTH: 6–12 m
COMMS: BLOS x Edge AI

02. Technologies

COMINT

TECH · SIGNALS

Communications Intelligence

Detection, interception and direction-finding of communications signals across the maritime spectrum, integrated directly into the platform and mission picture.

Ku-Band SATCOM

TECH · CONNECTIVITY

Beyond-Line-of-Sight Communications

Ku-band satellite communications, including on-the-move terminals, that keep autonomous platforms linked to command well past the horizon and through contested coastal waters.

03. Software | NEXUS A.I.

NEXUS is the single autonomy and intelligence layer that connects sensor data, the mission, and the decisions in between. One stack runs across AquaScan, ECHO, TANDAV and SURGE, so capability built once is reused across the entire fleet, from handheld to fully autonomous.

DATA

Fuses sonar, imaging and RF into one real-time picture, processed at the edge.

MISSION

Plans, adapts and executes autonomous missions, including swarm coordination.
