MOSA and JADC2 driving innovation in military vetronics applications
Vetronics systems today are increasingly focused on C4ISR [command, control, communications, computers, intelligence, surveillance, and reconnaissance], interoperability with other battlefield elements, and the capability to be optionally unmanned if necessary. They are also more likely to be built on open architectures as the U.S. Department of Defense (DoD) continues the push toward a modular open systems approach (MOSA) in upgrades and new designs.
