C4ISR systems are vital in delivering critical intelligence to military decision makers and operators for mission success. If the U.S. maintains current C4ISR investment levels, spending will reach $74.3 billion in 2024, according to a recent forecast report by Strategic Defense Intelligence. Unfortunately, many legacy C4ISR systems were built in stovepipes to fulfill a single mission requirement, leading to interoperability gaps in today’s technical, user-centric, and secure operational environments. Improvements need to be made when developing and fielding C4ISR systems.
