GUEST BLOG: enabling agile warfighter communications - CMOSS Mounted Form Factor (CMFF) Mounted Common Infrastructure (MCI) supports Ivy Mass. June 03, 2026 Deputy Product Manager, CMOSS Mounted Form Factor (CMFF), U.S. Army (Civ.), PM C2 Infrastructure. Modern military operations demand adaptable, interoperable, and resilient communications systems that keep pace with evolving mission requirements and technological advancements. At the recent U.S. Army Ivy Mass exercise conducted at Fort Carson (Colorado), the CMOSS Mounted Form Factor (CMFF) Mounted Common Infrastructure (MCI) demonstrated its vital role in delivering robust mission command-and-control capabilities. Developed and supported jointly by General Dynamics Mission Systems (GDMS) and Pacific Defense, CMFF showcased how modular open systems architectures, particularly the Sensor Open Systems Architecture, or SOSA initiative, are transforming tactical communications for the warfighter. What is Ivy Mass? Ivy Mass is a biennial dynamic division-level training exercise focused on operationalizing mission command and maneuvering across a wide range of combat and sustainment scenarios with 4th Infantry Division (4ID), held at Fort Carson, Colorado. Unlike traditional structured training lanes, Ivy Mass emphasizes free-range mission execution, enabling units to conduct attack, defense, joint fires employment (JFE), and logistics missions in a realistic and fluid operational environment. These complex scenarios require communications systems to be highly flexible, interoperable, and capable of integrating multiple subsystems seamlessly. CMFF MCI. CMFF MCI - a rugged, modular system built around the Army's C5ISR Modular Open Suite of Standards [CMOSS] - is a scalable, interoperable platform designed to host multiple communications and mission-command capabilities within a compact form factor suitable for mounting on tactical vehicles. At its core, CMFF integrates critical components such as positioning, navigation, and timing (PNT) devices; tactical communications; and software-defined systems. This integration enables commanders and soldiers to maintain real-time situational awareness, command and control, and effective communications across distributed units. Combined effort: GDMS and Pacific Defense. GDMS and Pacific Defense won the contract under the U.S. Department of Defense (DoD) MTA Rapid Prototype OTA acquisition vehicle to deliver the CMFF MCI. Initially developed through a rapid prototyping effort, CMFF leverages SOSA aligned principles to ruggedize and enhance the system, meeting rigorous operational standards. This approach enables rapid integration of diverse components and simplifies future upgrades. The open, modular design has been key to making CMFF MCI fully ready and capable for soldiers to use today. As prime vendors, GDMS and Pacific Defense delivered a comprehensive end-to-end solution, including system installation support, integration, hands-on training, and real-time troubleshooting, thereby ensuring CMFF MCI provides secure mission-tailored communications capabilities that directly support warfighter requirements. Enabling mission success with SOSA aligned principles. A key enabler of the CMFF's adaptability and interoperability is its foundation in the SOSA Technical Standard, which is a DoD-driven open architecture standard aimed at promoting modularity, scalability, and vendor interoperability across sensor and communications systems. CMFF MCI leverages SOSA aligned hardware and software standards to facilitate rapid integration of diverse components and subsystems. This open systems approach reduces vendor lock-in, shortens upgrade cycles, and simplifies logistics and sustainment, all critical factors in maintaining operational readiness in austere and rapidly changing environments. The SOSA approach's emphasis on common interfaces and modularity enabled CMFF MCI to leverage Silvus radios for beyond-line-of-sight communications, integrated PNT devices for precise location tracking, high dynamic range+ (HDR+) data links for high-bandwidth connectivity, and Lattice software for flexible network management, all within a single, ruggedized mounted chassis. Operational impact on Ivy Mass. During Ivy Mass, CMFF MCI proved indispensable in supporting the division's complex mission sets. Units operated across dispersed terrain, executing attack, defense, and sustainment missions that required continuous, reliable communications under dynamic conditions. CMFF's integration on 4ID's Joint Light Tactical Vehicles (JLTVs) enabled logistical support functions. Commanders from forward support companies (FSCs) leveraged the system to coordinate fuel resupply, maintenance, casualty evacuation, and battlefield circulation in real time. This capability ensured that maneuver units maintained momentum without disruption. Despite limited training time, soldiers rapidly developed confidence in operating the integrated CMFF communications suite through focused instruction on essential system functions and basic troubleshooting, enabling soldiers to maintain effective communication despite evolving mission requirements. During the exercise, on-site technical support ensured rapid resolution of integration issues, minimizing downtime and allowing soldiers to fully leverage CMFF's capabilities to sustain battlefield situational awareness. Future of command-and-control infrastructure. The success of CMFF MCI at Ivy Mass underscores the transformative power of modular open systems architectures like CMOSS and the SOSA approach in modernizing tactical communications. By enabling flexible integration of best-of-breed technologies from multiple vendors, these architectures foster innovation and resilience. Looking ahead, CMFF's scalable design means it can evolve along with emerging technologies, supporting future radio waveforms, cyberdefense capabilities, and networked sensors without costly system overhauls. This adaptability ensures that warfighters remain equipped with cutting-edge tools to maintain the battlefield advantage. Next-generation infrastructure. CMFF MCI, supported by GDMS and Pacific Defense, exemplifies next-generation tactical infrastructure. Its successful deployment at Ivy Mass demonstrates how modular open systems architectures, anchored in SOSA Technical Standard principles, enable agile, interoperable, and reliable communications that directly enhance warfighter effectiveness. As the Army continues to modernize its command-and-control systems, solutions like the CMFF MCI will play a pivotal role in delivering the operational flexibility and technical superiority that future conflicts demand. Ivy Mass was not just a test of systems; it was a proof point for the future of integrated, open architecture infrastructure solutions empowering soldiers at the point of need.

How General Dynamics Mission Systems champions Small Businesses. Suzanne Trinh from General Dynamics Mission Systems with Jack Macias from Pivot Manufacturing at WEST 2025. Pivot Manufacturing is a proud alumnus of the DOW Mentor-Protégé Program and one of its most valued small business partners. Every great mission needs the right team. At General Dynamics Mission Systems, that team extends far beyond the walls of one of the nation's premier defense contractors. It reaches into the heart of America's small business community, where innovation thrives, dreams are built and the future of national security is quietly being shaped. In honor of Small Business Day, General Dynamics Mission Systems, Inc. sat down with the General Dynamics Mission Systems Small Business Program manager, Suzanne Trinh, and Small Business Programs lead and senior supply chain analyst, Breonna Carver, to hear the story of a program that is strategic and breaking barriers so that domestic small business owner can thrive. More Than Compliance - It's a Strategic Priority For many, small business programs in defense contracting conjure images of paperwork and regulatory checkboxes. At General Dynamics Mission Systems, the reality is strikingly different. "Small business engagement isn't just a compliance requirement for us, it's a strategic priority that drives innovation and strengthens our supply chain," says Carver supply chain analyst. "When they succeed, we succeed, and more importantly, our warfighters get the best solutions possible." The small but mighty two-person team, responsible for everything from regulatory compliance and spend forecasting to hands-on mentorship and supplier matchmaking, operates with a sense of purpose that goes well beyond metrics. "Every small business behind every contract is someone's dream, someone's livelihood, someone's life work," Carver continued. "That is not lost on me, and I never take that responsibility lightly." Why Small Businesses? Because Innovation Lives There. General Dynamics Mission Systems partners with small businesses across a wide spectrum of capabilities - from cybersecurity and communications systems to highly specialized manufacturing. The reasons are both strategic and deeply human. Small businesses bring agility and innovation that complement company capabilities. They create a more resilient supply chain by diversifying the supplier base. They generate jobs and economic growth in communities across the country. And ultimately, they help General Dynamics Mission Systems deliver better solutions to the warfighters who depend on them. "We see small businesses not just as suppliers, but as strategic partners in our mission," said Small Business Programs manager, Trinh. UUVs and the Search for a Critical Supply Chain Partner Perhaps no story better illustrates the power of small business partnerships than what happened when General Dynamics Mission Systems faced a critical supply chain challenge for its unmanned underwater vehicles (UUVs). These sophisticated systems require highly specialized thermoformed plastic parts, a niche manufacturing capability possessed by very few suppliers. When the incumbent supplier exited the defense market, General Dynamics Mission Systems faced a serious situation: without those parts, the UUVs couldn't complete their missions. Over 18 months of diligent searching, prioritizing cybersecurity compliance alongside technical capability, the team identified multiple candidates from across the country. The contract was awarded to a small business. That small business is now a critical partner in national security - helping ensure that UUVs can perform mission-essential operations. "This story is a perfect example of why we invest in identifying and developing small business relationships before we're in crisis mode," Trinh shared. "Small businesses with niche, specialized capabilities can be mission-critical - and we never want to underestimate their impact." How General Dynamics Mission Systems Connects with Small Business Partners General Dynamics Mission Systems reaches small businesses through trade shows, industry events, matchmaking sessions and virtual outreach. "A trusted referral or warm introduction through one of our resource partners is far more effective than cold calls or unsolicited emails," Small Business Programs manager, Trinh explains. "When a resource partner says 'you need to talk to this company,' we listen. That context and credibility makes all the difference in starting a meaningful conversation." Key resource partners include: * APEX Accelerators - Compliance guidance and market research assistance * Small Business Administration (SBA) - Capital access, counseling and contracting support * Manufacturing Extension Partnership (MEP) Centers - Cybersecurity assessments, ISO support and workforce training * Project Spectrum - Defense Federal Acquisition Regulation Supplement (DFARS)/Cybersecurity Maturity Model Certification (CMMC) readiness tools and education * CMMC Partner Assurance Network (CPAN) - A newly launched initiative in partnership with Coalfire Federal, providing vetted CMMC readiness and assessment providers specifically organized to support suppliers in the company's network Breaking Down Barriers - So Small Businesses Can Succeed General Dynamics Mission Systems is candid about the challenges small businesses face: cybersecurity compliance requirements can feel overwhelming and knowing how to approach a large prime contractor is not always intuitive. But rather than leaving small businesses to navigate those challenges alone, General Dynamics Mission Systems leans in. Through education sessions, resource partner connections and programs like the Department of War (DOW) Mentor-Protégé Program - in which General Dynamics Mission Systems mentors one company at a time to ensure maximum focus and impact - the team actively invests in developing the next generation of defense suppliers. Support From The Top What truly sets the General Dynamics Mission Systems small business program apart is that support flows from the very top. General Dynamics Mission Systems president Chris Brady and vice president of Manufacturing and Supply Chain Troy Larson, along with the entire executive leadership team, are deeply committed to small business inclusion - making it a visible, embedded priority across the organization. "When executive leadership champions small business engagement, it changes everything," said Trinh. "It means resources are allocated, doors are opened internally and small business considerations are part of our strategic conversations - not an afterthought."
