Guidebook for Implementing Modular Open Systems Approaches (MOSA) in Weapon Systems
HQ AFMC/EN
11/07/2023
PDF
MOSA’s central tenet is that by requiring common standards and interfaces in its major platforms, components, weapons, and systems, future acquisitions of new capabilities and upgrades to legacy systems can be accomplished faster and at lower costs. MOSA can support greater competition, enhanced innovation, and more rapid technological refresh while reducing sustainment costs.
