New CMOSS Chassis, Plug-in-Card Prototypes in Development for Army Vehicles

The U.S. Army has selected two companies to develop prototype chassis and plug-in-cards for aviation and ground vehicles. The selection is the Army's latest milestone accomplishment in an effort to feature Modular Open System Approach (MOSA) -aligned embedded computing systems across all of the new investments it makes in technology upgrades for new and legacy vehicles.

In a program update posted in September 2025, the Army selected General Dynamics Mission Systems and Pacific Defense as the lead developers for new C5ISR/EW Modular Open Suite of Standards (CMOSS) Mounted Form Factor prototypes. CMOSS is a set of standards developed by the U.S. Army to guide the design of embedded computing networks featured on Army vehicles.
