The U.S. Navy is investing in Modular Open Systems Approach (MOSA) strategies to enhance systems engineering across naval operations, including air, surface, and subsurface systems. The Navy's MOSA guidebook, first released in January 2025, aims to bridge gaps between high-level policies and practical execution, with a second edition expected in early 2026.

The initiative seeks to improve response times to evolving operational environments by leveraging commercial technologies and diversifying the industrial base. MOSA is viewed as a strategic imperative to support procurement and modernization, enabling the Navy to adapt to new technologies and threats efficiently.
