Live Field Kinematics

Full-scale continuous extrusion attachment in tactical earth excavation

EXTRUSION CORE 400 mm Width
COMPACTION RATE >95% Proctor
85% - 95%
In-Situ Soil (ISRU)

Dramatically decreases reliance on imported materials and supply chains.

-90%
Supply Convoy Footprint

Replaces up to 60 concrete trucks with a single cassette transport vehicle.

0%
Portland Cement Required

Eliminates high-cost curing chemicals, additives, and precious potable water.

Standard 8T
Excavator Quick-Hitch

Interchangeable attachment directly deployed on existing engineering fleets.

Dual-Use Strategic Applications

One unified robotic architecture engineered for extreme front-line military survival and sustainable humanitarian shelter.

Hardening the Forward Edge in Contested Theaters

Modern loitering munitions, FPV suicide drones, and indirect artillery shatter traditional concrete barriers with lethal secondary spalling. CJC FORT provides continuous high-inertia soil monolithic domes and berms.

Drone & Indirect Fire Deflection:

Automated corbelled catenary domes provide direct overhead protection without complex formwork or vulnerable flat roof beams.

Lightening the Logistical Tether:

Eliminates up to 90% of cement convoy tonnage. A single tactical truck carrying sleeve cassettes replaces 60+ cement and gravel mixer trucks.

Force Preservation & Rapid Erection:

Reduces labor from a platoon of 30 soldiers digging for days down to 2 machine operators completing a bunker in 4–6 hours.
