MOSA for Defense & Warfare Summit 2026

The 3rd Annual MOSA for Defense & Warfare Summit will provide a forum for members of the DoW, Military Services, Industry, Academia, and other key stakeholders to discuss the warfighting imperative of implementing a modular open systems approach (MOSA) in the design, development, delivery, acquisition, and sustainment of modern defense systems.

Topics to be Covered

• Applications for MOSA: Space Systems
• Empowering the Next Generation of Air Dominance through MOSA
• Securing the Soldier's Future: Accelerating Warfighting Systems Modernization with MOSA
• Operationalizing Standards to Mandate MOSA and Achieve Joint Force Superiority
• Understanding the Role and Impact of Consortia in MOSA
• Strategic IP and the MOSA Imperative: Driving Competition and Agility for the Warfighter
• Leveraging MOSA to Revolutionize NAVAIR's Acquisition and Development of Warfighting Capabilities

Why You Should Attend this Year's Summit

$99.6 billion, representing approximately 26% of the Department's total investment funding ($384.3B), is requested for Major Defense Acquisition Programs (MDAPs) in FY 2026. Under U.S. law-specifically 10 U.S.C. § 4401 (formerly 2446a)-all MDAPs must be designed and developed using a Modular Open Systems Approach (MOSA) to the maximum extent practicable. This is no longer just a technical preference; it is a strategic mandate to counter rapidly modernizing adversaries. In his November 2025 memorandum, "Transforming the Warfighting Acquisition System," Secretary of War Pete Hegseth identified MOSA as a primary lever for "accelerating the speed of relevance." The Secretary has directed the Department to aggressively prioritize the delivery of modular systems to break vendor lock, foster competition, and ensure that the U.S. maintains a lethal technological edge through rapid, incremental upgrades. MOSA is the cornerstone of the Department's plan to prioritize adaptability, allowing for "plug-and-play" capability swaps in hours, not years, to accelerate innovation and lower life-cycle costs. This year's summit focuses on the operationalization of these mandates, providing you with the direct insights needed to navigate the new Warfighting Acquisition System (WAS) and the shift toward portfolio-based management

This year's MOSA for Defense & Warfare Summit brings together leaders from across the DoW, industry, and academia at the forefront of MOSA implementation. Attendees will gain insights into how these organizations are implementing this critical strategy and the resulting benefits.

The Summit will explore how MOSA is driving enhanced competition, innovation, interoperability, and cost-effective system design and delivery through open system development. By enabling easier and more cost-effective addition, removal, and replacement of components and subsystems, MOSA enhances program agility and reduces costs. This year's event will delve into MOSA's impact on key areas such as Space and Directed Energy. Attendees will also hear the role of Intellectual property laws play in MOSA and hear from the perspective of a Tri service panel. Connect with senior leaders and join the critical discussion around implementing open systems across the DoW.

The team specializes in the extensive research and development of our Summits' content and focus areas, and we will assemble the most respected minds in modular open systems approaches across the DoW, industry, and academia. Our non-partisan approach allows us to reach across all services and organizations to bring together a truly holistic group of decision makers and solution providers.
