Guest Blog: From Evangelism to Mandate: The Rise of MOSA

For many COTS [commercial off-the-shelf] vendors and VITA members, the Tri-Service Memo issued in January 2019 by the secretaries of the Army, Navy, and Air Force was the highest validation of several decades of their combined efforts.

The memorandum clearly stated that, going forward, modular open systems approach (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.”

Examples of MOSA standards include the Sensor Open Systems Architecture (SOSA) and CMOSS, both of which rely on OpenVPX hardware as their foundation.

For those individuals and companies who have worked together over the decades to further the activities of VITA and the VSO, this historic milestone can arguably be viewed as the point at which their collective efforts finally transitioned from evangelism to Department of Defense (DoD) mandate.

After years of working together to champion the performance, reliability, and cost benefits of COTS electronics, and the power of open architectures, that argument has emerged victorious.

Modular Open Systems Approach Solutions

Building on our years of experience and participation in the development of open standards, we design our range of semi-rugged to ultra-rugged solutions to bring the benefits of a Modular Open Systems Approach (MOSA) architecture to deployed ground, airborne, and naval platforms. Curtiss-Wright sets itself apart by leveraging proven components of our previously deployed, high-TRL designs and incorporating the latest rugged technology and cutting-edge capabilities. And, our hardware is manufactured through a trusted supply chain process and tested to the highest quality standards to minimize program risk.
