CMOSS Mounted Form Factor (CMFF)

As a trusted partner to the U.S. Army and other ground forces for over two decades, Leonardo DRS has designed, developed, manufactured, and delivered 300,000+ tactical computing systems and displays providing soldiers with improved situational awareness and networking on the battlefield.

Today, our intimate knowledge of the combat and wheeled vehicle fleet, coupled with our systems engineering rigor to meet the most stringent military requirements uniquely qualifies Leonardo DRS to provide the next generation of combat mounted computing platforms.

The next-generation combat computing platform is a ruggedized, lightweight, open architecture hardware system called CMOSS Mounted Form Factor, or CMFF, enabling users to insert plug-and-play networked capability cards including Assured PNT (APNT), mission command applications, and multi-band software defined radios. The Army plans to eventually replace several current tactical vehicle-based hardware systems with CMFF, which also brings significant size, weight, and power savings. Leonardo DRS’ solution is a CMOSS compliant CMFF system that has integrated Mounted Mission Command Software, APNT, Secure Communications, Electronic Warfare (EW) and offensive over the air Cyber. The new design is a 7 Slot CMOSS Chassis that supports a single board computer, 3 Payloads, APNT, Switch and Power Supply capabilities.


C5ISR/EW Modular Open Suite of Standards (CMOSS)

CMOSS refers to a set of standards developed to promote modularity, interoperability, and flexibility in command, control, communications, computers, combat systems, intelligence, surveillance, and reconnaissance (C5ISR) and electronic warfare (EW) systems. CMOSS provides guidelines and specifications for designing and integrating hardware and software components in military systems, particularly those related to C5ISR and EW functions. By adhering to CMOSS standards, developers and manufacturers can create systems and components that are compatible with each other, regardless of the specific platform or vendor. The aim of CMOSS is to enable rapid and cost-effective development, deployment, and upgrading of C5ISR and EW capabilities by facilitating the interchangeability of components and promoting common interfaces and protocols. This standardization enhances interoperability among different military systems and ensures that they can effectively communicate and cooperate in joint operations.


CMOSS Mounted Form Factor (CMFF)

The U.S. Army has defined a suite of open architecture industry and Army standards to enable the reduction of C5ISR/EW system size, weight, and power – cooling (SWaP-C) and ensure commonality across multiple platforms by enabling the sharing of hardware and software components among multiple C5ISR and Integrated Electronic Warfare System (IEW&S) missions. In January 2021, the Army approved an Abbreviated – Capability Development Document (A-CDD) for C5ISR/EW Modular Open Suite of Standards (CMOSS) Mounted Form Factor (CMFF) to establish an initial set of Army requirements desired to develop and employ these standards in prototypes for operational assessment.

The CMFF A-CDD establishes requirements for a prototype that minimizes the need for platform specific integration and enables the fielding of evolutionary capabilities without the need for additional cabling or mounts, or upgrades to the CMFF chassis. This CMFF capability is governed by the CMFF Reference Architecture which is guided and derived from technical requirements found in the CMOSS Interoperability Requirements Specification (IRS), specifically including the Sensor Open System Architecture (SOSA), Future Airborne Capability Environment (FACE), Vehicular Integration for C4ISR/EW Interoperability (VICTORY), and the Modular Open RF Architecture (MORA).

CMFF also includes requirements from the Standardized A-Kit Vehicle Envelope (SAVE) and the Mounted Mission Command (MMC) Environmental Specifications documents.  These standards will enable CMFF to drastically improve the reliability, reusability, interoperability, and interchangeability of CMFF system components to include the chassis, payload cards, radio conditioning devices, radioheads, and key software modules. CMFF systems and their payload cards are planned to be simple and intuitive to install, operate, and maintain by Soldiers, and be resilient, reliable, and available to operate in all operational air and ground environments and against any enemy.



Open Standards

Leonardo DRS proven past performance credentials ensures dependable Mission Critical computing capabilities are delivered. Leonardo DRS fully understands these combat platforms and the Soldiers that operate them. We are the reliable path to low risk CMFF solutions.

DoD Tri-Service Modular Open Systems Approach (MOSA) Directive

In January 2019 U.S. Department of Defense (DoD) issued the “MOSA for our Weapon Systems is a Warfighting Imperative”  Tri-Service Memorandum, signed by the Secretaries of the Air Force, Army & Navy. The memo directed the inclusion of MOSA standards in all requirements, programming and development activities for future weapon system modifications and new start development programs to the maximum extent possible.

The Open Group SOSA Consortium

The SOSA approach establishes guidelines for Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance and Reconnaissance (C5ISR) systems. The objective is to allow flexibility in the selection and acquisition of sensors and subsystems that provide sensor data collection, processing, exploitation, communication, and related functions over the full life cycle of the C5ISR system.
