enable commanders to see and un-derstand the battlefield so that they can make better and faster decisions. Citadel EBCS enables US, joint, and coalition interoperability while providing a suite of real-time battle planning aids and decision tools to effec-tively plan and execute the air and missile defence battle.

Why the Need for Citadel EBCS?Today’s air and missile defenders oper-ate against an ever improving, multi-dimensional threat in a highly com-plex and congested air battle-space where they are required to make rapid “life- or- death” engagement decisions, often based on only partial or ambigu-ous information. Citadel minimises this ambiguity by effectively networking all sensors and shooters into a holistic, system-of-systems AMD architecture which, for the first time, enables the commander and operators to benefit from a true SIAP.

As a result, with the Citadel system, commanders and operators can see

further, understand faster, react more quickly, and engage earlier with higher confidence while reducing the chances for fratricide and the wastage of limited interceptor inventory.

Interoperable and Affordable

Citadel is built on a modern, MOSA ar-chitecture using commercial standards that enables low cost and affordable systems integration.

Citadel EBCS builds upon US Standard C4I systems architecture, and may pro-vide nations that acquire the system interoperability with US and coalition forces. Other substan-tial benefits of Citadel include:

• Creates a modern, high speed, theater-wide C4I network to connect air and missile defence systems

• Performs critical battle manage-ment functions to optimise weapon system and sensor placement, to define the battlespace and to plan engagements

Up until recently, Air and Missile Defence (AMD) was character-ized by numerous stove piped,

disparate and cumbersome systems that provided only part of the bat-tlespace picture. Northrop Grumman has revolutionized the ability to fully in-tegrate AMD through its Citadel Enter-prise Battle Command System (Citadel EBCS), a Command, Control, Commu-nications, Computers, and Intelligence (C4I) system designed for Integrated Air and Missile Defence (IAMD). As the U.S. Army’s prime contractor for the In-tegrated Air and Missile Defence Battle Command System (IBCS), Northrop Grumman is leveraging its extensive develop-ment experience with IBCS to deliver Citadel EBCS to interna-tional customers as a robust, flexible, net-centric, Modular Open Systems Approach (MOSA)-based C4I system. Scalable and secure, Citadel EBCS affords low cost, low risk integration for an acquiring nation’s existing and future air and missile defence weapon systems. The Citadel system serves as a force multiplier by providing a common, Single Integrated Air Picture (SIAP) to

Force Structure AdvantagesThe Citadel EBCS MOSA and pub-lish/subscribe C4I network provides a significant force structure advan-tage by enabling the network to be both scalable and extensible. The flexibility afforded by the architec-ture eliminates proprietary stove-pipes and enables warfighters to easily and cost effectively upgrade their AMD systems architecture. By enabling component modernisa-tion without major system modifi-cations, Citadel EBCS will enable commanders and the warfighter to make more informed decisions faster and at significantly reduced cost.
