Description: The U.S. Army Capability Program Executive Command and Control Information Network (CPE C2IN), in strategic partnership with the Open Innovation Lab (OIL) at Aberdeen Proving Ground (APG), is pleased to announce an upcoming CMFF Chassis Plug Fest. This event is a collaborative technical demonstration focused on the Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, Reconnaissance (C5ISR) and Electronic Warfare (EW) Modular Open Suite of Standards (CMOSS) Mounted Form Factor (CMFF). It provides a unique laboratory environment for industry partners to validate the interoperability, standards-conformance, and mission-readiness of their CMFF-aligned hardware and software. Mission Purpose & Goals: The primary focus of this event is to identify additional Commercial or Non-Developmental CMFF aligned chassis, cards, and software applications that could provide immediate benefit to the Next Generation Command and Control (NGC2) ecosystem. This CMFF Plug fest will allow CMFF aligned chassis, Plug-In Cards (PICs) and software applications an opportunity to integrate with the Army's latest CMFF products, to advance the CMFF long term vision and ensure a robust, interoperable ecosystem for current and future payloads. Goal: COTS Readiness Evaluation Objective: Evaluate industry readiness to develop CMFF System of Systems for Ground and Aviation Platforms, including chassis, Plug-In Cards, Software, components and accessories, as a Commercial Off-The-Shelf (COTS) product lines. Goal: Advance NGC2 Integration Objective: Validate the integration of CMFF chassis and diverse payloads within the NGC2 technology stack to ensure seamless data flow across warfighting functions. Goal: Future-Proof Ecosystem Objective: Assess the ability of CMFF to support emerging payloads essential for NGC2, such as advanced processing, Artificial Intelligence (AI)/Machine Learning (ML) applications, and resilient communications. Goal: Standardized Interoperability Objective: Identify and resolve technical challenges related to Sensor Open System Architecture (SOSA) Application Programming Interfaces (APIs), Future Airborne Capability Environment (FACE) APIs, Vehicular Integration for C5ISR/EW Interoperability (VICTORY) data services, Modular Open Radio Frequency Architecture (MORA) interfaces, and network transport to ensure true "plug-and-play" capability. Event Details: Dates : 17 – 28 Aug 2026 Location : Open Innovation Lab (OIL), Aberdeen Proving Ground (APG), MD Format: Hands-on laboratory integration and structured test threads. Security: All participants must be US Citizens. Access to APG and the OIL facility will require valid Government-issued identification and prior security vetting. Who Should Participate: CPE C2IN encourages participation from industry partners currently developing or int…
