Introduction to C5ISR

What is C5ISR?

C5ISR stands for Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance and Reconnaissance. It reflects a belief that collecting, analyzing and distributing information in real-time are the keys to any mission, whether it's commanding soldiers, directing air traffic or safeguarding vast coastlines.

Integrated Systems

Raytheon specializes in linking different systems so that they operate as a coordinated whole. Our integrated systems include:

Command and Control (C2)

C2 networks support the flow of information, from planning to directing operations:


Analysts in every industry — from defense and law enforcement to financial and commercial services — are struggling to make sense of the enormous amounts of data at their disposal. Raytheon's analytics systems can take unstructured information, video and images from almost any source and turn them into relevant insights.


Raytheon's protected communications are aimed at serving the nimbler, tightly focused operations of today's changing military:

Data Encryption

A pioneer in technology for secure data, voice and other electronic communication, Raytheon is the leading developer and manufacturer of NSA-certified, high-reliability cryptographic microcircuits, ground units, and flight units for space communication. Our communications security devices include KIV-7 family of network link encryptors, advanced ASICs and cryptographic/acceleration equipment used in sensitive electronic messaging. Raytheon data encryption systems have achieved certification to the stringent CMMI Level 5 standard. Our quality systems have certification to the ISO 9001 international standard.
