LONDON, July 6 /PRNewswire/ --

Northrop Grumman Corporation (NYSE: NOC) held its third annual conference for
users of its Combat Electromagnetic Environment Simulator (CEESIM) systems for
the testing and evaluation of airborne, naval and land electronic warfare
systems. The conference has been established as a forum for constructive
dialogue with user groups aimed at keeping them updated about system
developments and identifying potential opportunities for improving system
performance and customer service.

More than 40 military and civilian personnel from the UK, German and Italian
user community were in attendance. A team of specialists in all aspects of
CEESIM engineering and support from Northrop Grumman Amherst Systems also joined
the conference. The conference was held in Peterborough in early June 2009.

Aircraft defensive aid systems are a vital part of the modern battlefield
environment and being able to test these electronic warfare systems in
accurately simulated combat conditions is critical to mission performance, said
John Stanfill, president of Northrop Grumman Amherst Systems. This conference
provides an opportunity for us to meet as an international user community with
the common goal of ensuring we have the best technology available to help
protect the warfighter. This is an important opportunity for us to hear directly
from frontline users about their operational experience and to learn where
system improvements could be made.

The Northrop Grumman CEESIM system is an industry-leading, advanced technology
simulator, which generates complex dynamic electromagnetic environments to
simulate true-to-war conditions, enabling military specialists to test and
evaluate the performance of advanced electronic warfare systems such as radar
warning receivers and electronic countermeasures and signals intelligence

The principal UK users of the CEESIM system are the Air Warfare Centre at RAF
Waddington, BAE Systems and Selex Sensors and Airborne Systems. International
users in attendance also included EADS Deutschland GmbH, Alenia Aeronautica
S.p.A. and Elettronica S.p.A.

Northrop Grumman's CEESIM is currently used to support a variety of
international aircraft including Typhoon, Tornado, Nimrod, Global Hawk, MRA-4,
Harrier, AWACS and Apache. The company was selected last year to supply CEESIM
systems for the A400M.

In addition to CEESIM, attendees were briefed on the Signal Measurement System,
the IR/EO based Realtime IR/EO Scene Simulator and the CEESIM-based Joint Threat
Emitter (JTE), a ground-based, electronic warfare system selected for use by the
U.S. Air Force for use on all their electronic warfare training ranges. JTE is
able to use any threat data developed on CEESIM systems. Along with product
briefings, product demonstrations were also given at a special half day session.

Northrop Grumman Amherst Systems produces deployable radio frequency (RF) and
infrared (IR) frequency simulators for use on test and training ranges at
military installations worldwide. Its RF and IR simulators test the world's most
advanced electronic warfare warning systems, infrared/ultraviolet missile
approach sensors and radar-warning receivers and jamming systems. These
simulators are in use internationally, not only in the UK, Germany, and Italy,
but also in Australia, Canada, Taiwan, Japan, Singapore, Korea, Saudi Arabia,
UAE, Israel, Sweden, Finland, Norway, France and other NATO countries.

Northrop Grumman Corporation is a leading global security company whose 120,000
employees provide innovative systems, products, and solutions in aerospace,
electronics, information systems, shipbuilding and technical services to
government and commercial customers worldwide.
