What is the Modular Open Systems Approach (MOSA) Directive?
On January 7, 2019, the U.S. Department of Defense (DoD) issued a memo, signed by the Secretaries of the Army, Air Force, and Navy, mandating the use of the Modular Open Systems Approach (MOSA). The memo states that “MOSA supporting standards should be included in all requirements, programming and development activities for future weapon system modifications and new start development programs to the maximum extent possible.” This mandate for MOSA was even codified into a United States law (Title 10 U.S.C. 2446a.(b), Sec 805) that states all major defense acquisition programs (MDAP) are to be designed and developed using a MOSA open architecture.
The MOSA directive has accelerated the adoption of a variety of open standards, such as The Open Group Sensor Open Systems Architecture™ (SOSA) and the U.S. Army CCDC C5ISR Center’s C5ISR/EW Modular Open Suite of Standards (CMOSS), that have been adopted by the three military branches.
Adopting a MOSA open architecture offers a wide range of benefits:
- Interoperability: Common standards enable seamless sharing of information across domains and between machines
- Flexibility: Moving away from proprietary pinouts provides choice of best-in-class technology without vendor lock-in
- Simplicity: Interoperability makes it easier to add new functionality and upgrade or replace existing technology
- Investment Protection: Ability to choose parts from multiple vendors lowers life cycle management risks
- SWaP Optimization: Increased interoperability reduces the number of systems required to field new technology, which in turn eliminates clutter caused by redundant cabling and accessories
