CEMA Solutions for Defence

CACI are partners across the UK and US national security and defence for communication command and control tools helping secure national interests across the electromagnetic spectrum. CACI is a global leader of Cyber Electromagnetic Activities and Command Control Communication and Intelligence (C3I) solutions; a core service and capability subject to continual research, development, test and evaluation to counter emerging threats and adversary capabilities.  We cohere mixed hardware and toolchains, reduce integration risk, and enable assured mission coordination through open-standard common services. 

What we do  

• Common Services & interoperability: All Domain Overhead Co-operative Operations Common Services (AOCO CS) let EMS nodes join the right networks regardless of CONOPS or service alignment 
• Open-standard alignment: designed and delivered against the JICD ecosystem 
• Development & O&M: build and sustain software-defined services, brokers/adapters, processors, and mission services 
• Integration playbooks: clear integration principles for onboarding new nodes and partner services 
• Secure sustainment: regression/integration testing, containerisation & deployments, diagnostics, security patching, and software refreshes 

Proven in Defence

CACI designed, delivered, and sustained AOCO Common Services –JICD-aligned, open-standard software that lets UK Government CEMA assets register, share capabilities/status, and interoperate across the electromagnetic spectrum. They established a disciplined SAFe delivery and O&M model with integration guidance, testing, containerised deployments, security patching, and onboarding support, reducing integration risk and accelerating reliable mission coordination. 

UK/US Governments – Delivering Effective Command and Control through Cyber Electromagnetic Activities (CEMA). 

Challenge

Robust CEMA systems are at the core of delivering a mission, sensing, deciding and effecting to increase lethality and survivability. Disparate and disconnected CEMA hardware and tool suites created integration gaps and communication breaks during complex missions, driving cost, risk, and reduced operational effectiveness. The customer needed a coherent, standards-aligned way to connect assets and coordinate CEMA tasks at pace and scale.

Solution

• Delivered Development and Operational Maintenance for AOCO Common Services, software-defined protocols and tools that let EMS nodes join relevant networks irrespective of CONOPS or service alignment 
• Built software-derived services aligned to the Joint Interface Control Document (JICD) to plan and coordinate CEMA missions and tasks 
• Deployed a 15-strong UK/US team (developers, engineers, delivery specialists) from CACI’s global CEMA & ISR operations 
• Engineered and maintained three core services: Registration, Capabilities, and Status (RCS) – under SAFe 
• Produced detailed integration guidance to accelerate onboarding of new nodes and services 
• Sustained the platform with software development, third-party onboarding support, diagnosis & resolution of performance issues, regression/integration testing, containerisation & deployment updates, and security patches/software refreshes 

Outcomes

• Reliable, responsive maintenance with continuous alignment to operational requirements 
• Improved interoperability across the JICD-aligned mission ecosystem 
• Seamless onboarding for partners and services via clear integration principles 
• Better control & coordination of assets, enhancing decision-making across the chain of command
