RAMPART 10 Slot Rugged 3U VPX Chassis
A Secure, Configurable CMOSS Mounted Form Factor (CMFF) Solution
The General Dynamics Rampart™ family of chassis is designed to enable the vision of a standards-based C5ISR ecosystem promoting system upgradability, modularity, reduced SWAP, improved logistics, and rapid capability evolution.
Supported by the broad availability of 3U OpenVPX™ payload capabilities, the Rampart chassis can support a wide range of mission configurations including Edge Computing, Networking, Communications, EW/ELINT, and beyond.
The modular, upgradable nature of 3U OpenVPX and standards-based architecture enable rapid system reconfiguration.

Features
Scalable
Providing 10 total 3U VPX module slots in a single Standard A-Kit Vehicle Envelope (SAVE) profile, the Rampart™ chassis maximizes the amount of C5ISR capability that can be delivered in SWAP constrained platforms. The chassis and mounting tray can be directly installed in the footprint of existing vehicle radio systems and use standards-based interfaces for broad platform compatibility.
Survivable
The chassis is designed to meet the rigorous Ground Mobile and Aviation requirements set forth in the Mounted Mission Command Environmental and Quality Specification (MMC EQC). Includes operation in +71C ambient conditions, immersion and wash down conditions, multiple 810G vibration and shock profiles, MIL-STD-461 EMI, and MIL-STD-1275 / MIL-STD-704 power environments.
Secure
The Rampart chassis features complete physical and electrical separation between two enclaves, including a contiguous isolation boundary across the backplane. These provisions ensure the chassis is positioned to support applications requiring security certification. The chassis supports operation as single, dual, or multi-domain system depending on switch slot population and configuration.
