Strategies for modernizing older, proprietary systems with modular, open components.

The future of military aviation isn't being written in a lab, it's unfolding in real time. The Lakota Connector Team (Airbus, L3Harris Technologies, Shield AI, and Parry Labs) will offer an unfiltered look at what it actually takes to answer an urgent call from the U.S. Government and rapidly develop an autonomous capability against an identified gap. This program is moving fast, and this panel puts you in a front-row seat as the team builds it. The Lakota Connector Team will pull back the curtain on one of the most compelling active examples of MOSA working exactly as intended. Hear directly from the leaders who assembled a multi-company team around a real and pressing operational need, divided scope according to genuine core competencies, and are now navigating the honest challenges of building a high-performing coalition at speed. The conversation will cover the full picture: rapidly modifying a proven commercial platform, applying the systems integration discipline required to unify multiple mission technology providers under one architecture, scaling an autonomy technology already operating across weapon systems and built to grow toward collaborative autonomy, and deploying an open C2 infrastructure designed from day one to plug into any command ecosystem from Marines to SOCOM to customers not yet in the room. This isn't a program brief. It's a live look at what open architecture delivers when the stakes are real, the timeline is compressed, and the work is still underway.

Senior leaders from the Tri-Service community and Office of the Secretary of War (OSW) share a high-level perspective on MOSA priorities, defense modernization, interoperability, and government–industry collaboration. The keynotes will highlight strategic direction, emerging opportunities, and the path forward for accelerating MOSA adoption across the defense enterprise.

This panel will discuss the practical implementation of MOSA principles to the space flight avionics industry. Experts from government and the commercial space sectors will address both the opportunities and challenges they see ahead with this approach. Traditional bespoke satellite systems are expensive, incur long development schedules, and not suited for reusability or sustainability. New mission profiles demand shorter design cycles at lower cost. Government space programs and industry manufacturers have moved towards modular systems, however the standardization and compatibility across systems and vendors remains a challenge. To enable these missions, space hardware needs to standardize designs for maximum interoperability and reuse. The commercial space market has shown a clear desire to adopt standards including VPX and VNX+ form factors and interfaces including PCIe and Ethernet, however these standards alone may not fully close the gap on providing truly modular and interoperable system components across vendors. The newly released SOSA Space Appendix aims to become the new standard interoperable hardware for space designs going forward.

How leading standards organizations are collaborating to create a more unified and interoperable ecosystem.

The Department of Defense is increasingly relying on the Modular Open Systems Approach (MOSA) to enable adaptable, interoperable systems across complex acquisition programs. While MOSA principles are well established in policy and guidance, applying them across real programs requires aligning digital engineering practices, system architectures, and data integration strategies across multiple organizations and technology environments. This panel will examine how MOSA is being implemented in practice across digital engineering, modeling and simulation, and operational system integration. Discussion will focus on how open standards, data architectures, and modular system design contribute to interoperability across system-of-systems environments. Topics will include the role of digital engineering in supporting MOSA implementation, approaches for integrating models and simulations with operational systems, and lessons learned when applying modular architectures across evolving defense programs. The discussion will also explore how data interoperability and architectural governance influence the long-term adaptability and sustainment of MOSA-based systems. Attendees will gain practical insight into how MOSA principles translate from policy into real system architectures, and what technical and organizational challenges must be addressed to achieve interoperability across complex defense ecosystems.

As defense and aerospace systems grow more software-defined and interconnected, cybersecurity can no longer be treated as a perimeter function. Modular Open Systems Approach (MOSA) offers a path toward building security directly into system architecture through strong partitioning, modular design, and controlled integration of components. This panel will examine how MOSA principles can improve system security by enabling isolation of critical functions, reducing attack surfaces, and allowing independent verification and certification of system components. Panelists will discuss how separation kernels, virtualization, and modular software frameworks allow safety-critical, security-critical, and general-purpose applications to coexist while maintaining strong boundaries between them. The discussion will also explore how modular architectures enable faster security patching, technology refresh, and algorithm upgrades without requiring full system redesign. Additional topics include securing heterogeneous compute platforms (CPU/GPU), managing supply-chain risk through component modularity, and enabling zero-trust architectural approaches in mission systems. Real-world examples from aerospace and defense programs will demonstrate how MOSA enables resilient systems that can adapt to evolving cyber threats while maintaining safety and certification requirements. Attendees will gain practical insights into how security can be designed into modular architectures from the start rather than added later as a reactive measure.

As combat operations increasingly encounter challenging conditions, the integration of Degraded Visual Environment (DVE) solutions and sensor fusion technologies has become pivotal to mission success and safety. This panel at the 2026 MOSA Summit will examine how open, modular approaches are driving innovation in DVE and sensor fusion, enabling systems to adapt rapidly and interoperate across platforms. Our distinguished moderator and expert panelists will share their experiences implementing open system principles to streamline sensor integration, enhance situational awareness, and meet the Modular Open Systems Approach (MOSA) mandate for conformance and interoperability. Panelists will discuss real-world applications—from military aviation to ground systems to commercial aviation—highlighting lessons learned, technical achievements, and remaining challenges in deploying DVE and sensor fusion capabilities. Through an interactive format, attendees will be encouraged to engage with the panelists, ask questions, and share perspectives. By the end of this session, participants will gain practical insights into adopting open architectures for DVE and sensor fusion, empowering them to accelerate innovation, improve verification processes, and ensure system resilience in complex operational environments.

A Modular Open Systems Approach (MOSA) is only as effective as the tools and frameworks used to specify and exercise it. The SOSA® Approach — built on business processes, proven technical practices, and a consensus-based open standard — gives Government the precision to better define their MOSA and enables Industry to better execute it. This panel brings together Government and Industry voices to explore how the SOSA Approach delivers real, tangible benefits to both sides of the acquisition relationship: reducing lifecycle costs, accelerating technology insertion, and enabling a competitive, interoperable supplier base. Attendees will leave with a clearer understanding of how to leverage the SOSA Technical Standard in their programs today.

As MOSA-aligned processing subsystems—driven by SOSA™, CMOSS, and FACE™ standards—become the norm, the focus must shift from physical interoperability to operational management. While modular hardware ensures components fit, it does not guarantee they behave coherently in complex, multi-vendor environments. This panel explores why standardized system management (software-defined interfaces, health monitoring, configuration, orchestration, and unified security) is critical to realizing the full potential of MOSA. Experts will discuss how standardized management reduces integration bottlenecks, accelerates capability insertion, and enables automated, real-time health diagnostics across high-performance computing subsystems. Without standardized management layers, we risk replacing "stove-piped" hardware with "stove-piped" management software. Join industry and government leaders as they define the path forward for unified, interoperable management frameworks that ensure system readiness, resilience, and true plug-and-play capability for the warfighter.Key Discussion Points: - Moving from physical standards (hardware) and reference system architectures to system-level implementation standards (management/software). - Standardizing health monitoring, network administration, configuration, orchestration, diagnostics, and security. - The role of MOSA in simplifying system management of multi-vendor subsystems.

Large Language Models (LLM) prompt volume has grown 80% this year, and now a full one-third of all consumers rely entirely on the AI summary. Agentic AI, capable of setting its own goals, making decisions, consuming resources, and executing tasks – is dominating trends and pushed heavily into the public and private sectors. But ask yourself: what do LLMs and agentic AIs have to say for certifying conformance in MOSA? How reliable are their claims? This panel will explore these questions. Our distinguished moderator and panelists are experts in applied MOSA standards and reference architectures. Using a structured rubric, we will evaluate the top 3 LLM responses against common conformance questions in the MOSA community. Then, we’ll compare and score those answers against expert testimony. The panel will present our experiences applying AI to evaluating conformance to open systems standards and give pointers for future applications. We share our findings and let you be the judge. A unique, eye-opening discussion not to be missed!

Radio frequency signals underpin communications, navigation, sensing, and other critical systems, yet they remain difficult to interpret with traditional tools. Most radio activity is viewed through spectrum analyzers that present two-dimensional slices of an inherently multidimensional domain. As new technologies like 5G, IoT, and satellite networks proliferate, these flat interfaces are increasingly inadequate for understanding dense and dynamic signal conditions. This session explores how AI-enhanced modeling reveals patterns, direction-finds emitters, and uncovers relationships that are difficult to detect through manual analysis. By fusing multiple measurements with contextual data, these approaches reconstruct richer representations of radio behavior, capturing congestion, interference, and network interactions across training and operational scenarios. As a result, anomalies and signal relationships can be identified far more quickly than through expert-driven analysis alone. We will examine how mixed-reality visualization translates these modeled datasets into immersive spatial views, allowing users to perceive emitters and networks within their natural three-dimensional context. Together, these approaches reduce cognitive burden, improve spectrum awareness, and enable more effective training, simulation, and mission rehearsal. Practical examples will illustrate how advanced spectrum analysis techniques and XR visualization improve decision-making in contested electromagnetic environments.

Modular Open Systems Approach (MOSA) is fundamentally transforming how the Department of War (DoW) designs, builds, and sustains its warfighting systems. Moving beyond a mere pursuit of efficiency, MOSA is now a primary driver of combat capability, enabling the DoW to out-innovate and defeat adversaries. This panel will examine how MOSA is being operationalized to deliver a direct competitive advantage to the warfighter. At its core, MOSA is the critical "enabling tissue" that allows the rapid transition of prototypes from labs to the front lines at a pace measured in weeks, not years. By enforcing open standards and ensuring interoperability, the DoW’s Acquisition Transformation Strategy (ATS) breaks historic vendor lock-in, drives down costs, and allows the U.S. military to integrate the best available technology from a diverse industrial base. As MOSA becomes a mandatory component of program planning, Program Managers are now required to develop comprehensive MOSA strategies. This panel will investigate how MOSA is being operationalized across the defense acquisition enterprise to accelerate modernization and interoperability. We will also examine how successful MOSA strategies are being tailored to integrate both technical and business imperatives across the defense acquisition enterprise.

Senior leaders from the Tri-Service community and Office of the Secretary of War (OSW) share a high-level perspective on MOSA priorities, defense modernization, interoperability, and government–industry collaboration.

Panelists will share practical insights on integrating MOSA into acquisition and sustainment strategies, managing technical and business tradeoffs, and aligning contracting, engineering, and program management communities. Grounded in Department policy and guidance, acquisition workforce MOSA implementation pain points data, including the MOSA Guidebook and coordinated IP guidance, the session will explore how MOSA is being scaled beyond compliance to enable interoperability, competition, and rapid technology insertion. Attendees will gain actionable perspectives on workforce readiness, enterprise implementation challenges, and opportunities for deeper government–industry collaboration to drive sustained, enterprise-wide MOSA success.

The Department of War (DoW) is accelerating its shift toward acquiring weapon systems and subsystems from commercial suppliers. Commercial firms are seen as rapid innovation leaders, manufacturing in higher quantities that generate lower costs while quickly discarding even recent 1- to 2-year-old technologies to stay competitive. Military firms design systems for obviously military purposes and interoperability, prioritizing smaller quantities, long term sustainment, military-grade hardening and military specific testing. This mismatch creates a structural challenge: How can the DoW continuously integrate new commercial capabilities into long lived military vehicles? This panel will explore the use of MOSA to allow that to happen, what will incentivize military and commercial suppliers to support it, and what the military can do within the acquisition process to accelerate it.

MOSA means many things to many stakeholders. We'd like to draw a few lines in the sand to return to first principles; why are we all "doing MOSA"? And ask the question, are the actions being taken in industry, and in DoW acquisition truly aligned to those principles?

The era of one-on-one electromagnetic warfare engagements is all but over. As adversaries enhance their electronic protection capabilities, modern battlefields increasingly rely on collaborative operations involving sensors, jammers, and decoys distributed across diverse platforms such as drones, aircraft, ships, ground vehicles, and dismounted soldiers. To enable the increasing level of collaboration required for battlefield dominance, electromagnetic warfare systems must feature standardized interfaces to streamline communication and interoperability across the battlespace. Without common interfaces built on open architecture and Modular Open Systems Approach (MOSA) principles, integrating and testing the multitude of systems and system configurations found on the battlefield will be too complex and costly to be practical. This panel will explore how existing and emerging MOSA and open standards are driving the future of collaborative electromagnetic warfare. Expert panelists will address key challenges, share their insights, and discuss opportunities to develop flexible, scalable, and interoperable solutions for tomorrow’s multidomain EMSO battlespace.

This panel addresses the Navy's urgent requirement for resilient navigation in GNSS-denied environments through Colvin Run Networks' FALCON Testing Open System Architecture (TOSA). Developed in support of Navy SSP's Multi-Service Advanced Capability Hypersonic Test Bed (MACH-TB), FALCON serves as a universal test harness for alternative PNT technologies. Panelists will show how FALCON applies MOSA standards to decouple sensor-specific logic from the navigation core behind stable, well-defined interfaces hosted on modular, heterogeneous hardware. This enables inertial, magnetic, optical, signals-of-opportunity, and emerging PNT payloads to be integrated and evaluated without reengineering core interfaces. The session highlights innovations engineered for the thermal and vibrational extremes of Mach 5+ flight: a real-time hybrid Kalman-ML estimator that pairs a rigorous Bayesian filter with learned bias correction; a deterministic edge runtime built for hard real-time execution on embedded compute platforms; resilient handling of out-of-order sensor delivery across a DDS data fabric; automated digital-twin generation; and edge-first telemetry visualization. Attendees will see how marrying open-architecture standards with ML-augmented fusion enables software- and hardware-in-the-loop evaluation against ground-truth datasets, reducing integration risk and accelerating flight-test readiness for hypersonic platforms.

The Department and the defense industrial base (DIB) face a range of challenges as they accelerate guided munitions production.
