Northrop Grumman Launches Portable System for CBRN Incident Monitoring and Assessment

LONDON, March 25, 2011 - Northrop Grumman Corporation (NYSE: NOC) has launched its new Integrated
Tactical Rapid Assessment of CBRN Environments (I-TRACE) system, a
man-portable capability for the monitoring of Chemical Biological
Radiological and Nuclear (CBRN) incidents and the collection and handling of
related data.

I-TRACE facilitates decision support and enhances situational awareness
and information sharing among emergency response organizations. The system
requires no specialist vehicle installation and can be rapidly deployed using
existing "blue light" emergency services vehicles. Access to all data and
situational awareness is achieved through a web portal which is controlled
using role-based authorized access.

"Command and control systems are critical to the successful management
and coordination of a CBRN event. I-TRACE brings together key information
assets to give users a common operational picture and provide emergency
responders with an integrated analysis and response capability to help
minimize the effect of CBRN attacks," said Paul Davison, vice president
Defence, Northrop Grumman Information Systems Europe.

The system provides a flexible, multi-layer solution and has a versatile
architecture and scalable configuration making it suitable for use in a wide
range of situations and environments. I-TRACE can be integrated with third
party meteorological, visual and CBRN sensors to provide situational
awareness of a CBRN incident to local and remote commanders, and other
interested parties at remote locations. In addition, the raw sensor data is
available to analysts for specialist analysis using existing analysis
software.
