Rapidly Advancing the Latest Technology and Innovations to the Warfighter

The Avionics Architecture Team (AAT), also known unofficially as the Open Architecture Engagement (OA) team, is comprised of experienced OA subject matter experts (SMEs) with focused OA and Modular Opens Systems Approach (MOSA) participation and resources. That includes Software and Hardware Open Systems Standards, Platform Integration and Modeling, Open Systems Management Plans (OSMP), as well as MOSA Guides and Strategies for Air, Ground and Sea Platforms. In addition, they provide customized training, tailored implementation and life cycle support when executing a MOSA.   

Collaborating with Joint Service OA experts, AAT also works with Industry and Academia in concert with integrators, module vendors, and related open standards groups and consortia. The AAT Open Architecture SMEs support Program Managers, IPT Leads, Engineers and Logistics. Several AAT members have also been embedded in identified Program Offices to help them meet their Open Architecture MOSA needs on cost, schedule and performance objectives.

Open Systems Management Plan – the Backbone of Modular Naval Capability

The Open Systems Management Plan (OSMP) serves as the blueprint for managing costs while continuously innovating; aligns Navy acquisition strategies with goals of cost optimization, increased competition, and long-term sustainability. Through its structured framework, the OSMP facilitates integration of modular solutions, and enables enhancement of system capabilities affordably while avoiding dependence on proprietary technologies. By adopting MOSA, warfighters gain adaptable, cutting-edge systems to evolve with their needs and challenges - to not only perform today but be ready for tomorrow’s mission.

Implementing a Modular Open Systems Approach in Department of Defense Programs

By the Office of the Under Secretary of Defense for Research and Engineering, this February 2025 document provides the Department of Defense (DOD) community, including Military Services, civilians, and DOD support contractors with information to help ensure programs incorporate a modular open systems approach (MOSA) as part of the defense acquisition program life cycle. The intended audience includes decision makers, program management offices (PMOs), program managers (PMs), and program lead systems engineers responsible for implementing and evaluating MOSA in defense programs.

Naval Modular Open Systems Approach Guidebook Version 1.0

“It is with great pride and anticipation that I present this Naval Guidebook for implementing a Modular Open System Approach (MOSA). The guidebook focuses on the operational imperative of designing flexibility into our products and business models and represents a significant step forward in our ongoing commitment to enhancing the flexibility, interoperability, and cost-effectiveness of our naval systems. As the Assistant Secretary of the Navy for Research, Development, and Acquisition (ASN-RDA), I have witnessed firsthand the transformative impact that MOSA can have on our naval capabilities.” – HON Nickolas H.
