    UWC(under water cache)

    The Underwater Cache (UWC) system is an advanced concealment technology designed to submerge inflatable boats and outboard engines to prevent any exposure of the team’s location during infiltration and maritime special missions.
    By forcing the air out of the boat’s compartments, the vessel is hidden beneath the surface near the objective area, effectively evading enemy coastal radar and visual surveillance while maintaining strict operational secrecy.
    Engineered for rapid response, the system utilizes compressed air cylinders to swiftly resurface the hull during emergency scenarios or upon mission completion, enabling immediate propulsion and swift extraction.

    Air Valve Adjustment + Venturi Kit Connection
    (Open Intercom Valve / Open Internal Hull Valve / Keep Stern Closed)
    04
    Deflation Procedure: Allow Air to Escape from the Stern First and Sink Gradually
    (Close the Valve and Secure the Cover Before Submersion)
    05
    Proceed with underwater concealment while ensuring that water does not enter the internal valves of the inflatable boat. (Close the Valve and Secure the Cover Before Submersion)
    06
    Manually Force Air Exhaustion to 80–90%
    07
    Completely Exhaust the Remaining Air Using the Venturi Kit
    (Remove the Venturi Kit only while it is operating, after confirming vacuum condition)
    08
    Move to the Concealment Location and Secure the Boat
    Key Features
    Rapid Deployment & Concealment- Automated Inflation: Fully inflates all compartments within 60 seconds using compressed air cylinders for immediate mission readiness.
    - Full Deflation System: Provides a dedicated Venturi Kit to achieve complete vacuum-level deflation after natural exhaustion, ensuring perfect underwater concealment.
    Optimized for Special Operations- Aerial & Underwater Deployment: Features a foldable floorboard structure, allowing for deployment from aircraft or surface vessels followed by underwater resurfacing.
    - Submersible Engine Bag: Includes a specialized bag that allows the outboard motor to remain mounted during concealment, saving critical time and increasing operational efficiency.
    Stability & Versatility- Multi-Purpose Operation: Designed for versatile use; modular floorboards can be installed on land or ship decks depending on mission requirements.
    - Enhanced Durability: Constructed with high-strength, abrasion-resistant materials engineered for extreme maritime environments and tactical demands.
