Northrop Grumman Holds CEESIM International Users' Conference in the UK

LONDON - April 18, 2008 - Northrop Grumman Corporation (NYSE:NOC) held its second annual conference for users of its Combat Electromagnetic Environment Simulator (CEESIM) systems. The conference aimed at keeping users updated on system developments and identifying potential opportunities for improving system performance and customer service.

More than 50 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 on April 16.

"Aircraft defensive aids 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 is an important opportunity for us to brief the user community on the latest capabilities of the system and to understand user requirements so that we can continually improve the quality of the system."

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 systems.

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 include EADS Deutschland GmbH and Alenia Aeronautica 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 has been selected to supply several CEESIM systems and expects future expansion potential for the A400M, ASTOR, JSF, C-130J and various helicopter programs.

In addition to CEESIM, attendees were briefed on 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.

Northrop Grumman Amherst Systems produces deployable radio frequency (RF) and infrared frequency (IF) 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 but also in such countries as Germany, Italy, Germany, Australia, Canada, Taiwan, Japan, Singapore, Korea, Saudi Arabia, UAE, Israel, Sweden, Finland, Norway, France, and other NATO countries.

Northrop Grumman in the UK operates from primary locations at: Fareham, Coventry, New Malden, Peterborough, RAF Waddington and Solihull providing avionics, communications, electronic warfare systems, marine navigation systems, robotics, C4ISR solutions and mission planning, IT systems and software development.

Northrop Grumman Corporation is a $32 billion global defense and technology company whose 122,000 employees provide innovative systems, products, and solutions in information and services, electronics, aerospace and shipbuilding to government and commercial customers worldwide.
