Northrop Grumman Corporation has submitted its proposal for the development and integration phase of the U.S. Marine Corps Common Aviation Command and Control System (CAC2S). The CAC2S provides a complete modernization of the Marine Air Command and Control System. CAC2S will replace dissimilar legacy systems with a common, open, modular, scalable design based on proven, high-technology readiness level hardware and software components. "In addition to meeting all CAC2S requirements, Northrop Grumman's best-value solution is a truly expeditionary package that can perform direct air support center functions while on the move," said Pat Camacho, vice president of integrated command, control, communications and intelligence systems for Northrop Grumman Information Systems. "All core electronics components are integrated on Humvee platforms and preconfigured with data and communications capability between the operations center and antenna hill". Northrop Grumman's cost-effective offering builds on and enhances the communications, processing and display functionality previously developed. It also integrates critical sensor and data communication capabilities including Link 16, the Composite Tracking Network and AN/TPS-59 and AN/TPS-63 radars. The system can scale up to the much larger Tactical Aviation Command and Control Center variant without additional core electronics equipment at the operations center. Northrop Grumman's innovative network design scales up to 216 workstations by using a series of fault-tolerant Ethernet circuits.
