How a Modular Open Systems Approach (MOSA) Will Enable JADC2

November 02, 2021 | BY: David Jedynak

What is Joint All-Domain Command and Control (JADC2)?

Traditionally, tactical networks developed by each military branch have been unable to interface with one another, hindering the ability to share intelligence and quickly make decisions or issue commands based on said intelligence. To address this problem, the DoD has introduced a concept called Joint All-Domain Command and Control (JADC2).

JADC2 aims to connect sensors from the Army, Air Force, and Navy into a single cloud-like network that will enable swifter, more informed decision making. Each military branch is leading an effort to implement JADC2; for example, the Air Force is developing a network, dubbed the Advanced Battle Management System (ABMS), that will transmit its collected data across domains.


What is MOSA?

A Modular Open Systems Approach (MOSA) is not itself a technical standard. Rather, MOSA is an acquisition and design strategy that prioritizes the use of open standards-based technology for, as the Defense Standardization Program states, "designing an affordable and adaptable system."

The major push toward MOSA took place in 2019 when the U.S. DoD issued a memorandum with the subject "Modular Open Systems Approaches for our Weapon Systems is a Warfighting Imperative." The very first paragraph in the memo states, “Victory in future conflict will in part be determined by our ability to rapidly share information across domains. Sharing information from machine to machine requires common standards.”

The memo goes on to say that the Secretaries of the Air Force, Army, and Navy have reviewed the open standards that have been developed, demonstrated, and validated in their respective branches for the past several years. Deeming the continued use of such open standards "vital to our success," the memo mandates that MOSA supporting standards should be included in requirements for all weapons systems going forward.


How Will MOSA Enable JADC2?

One of the main benefits of leveraging common standards is that it ensures interoperability between systems, whether they're on the same platform, different platforms in the same combat team, or even across domains. This enhanced level of cross-platform communication is the goal behind JADC2. And, as the mandate for use of MOSA standards in all new defense programs has been codified into U.S. law (Title 10 U.S.C. 2446a.(b), Sec 805), it makes sense that MOSA supporting standards will undoubtedly play a key role in realizing the DoD's JADC2 vision.
