BUFFALO, N.Y., Dec. 1, 2011 (GLOBE NEWSWIRE) -- Northrop Grumman
Corporation (NYSE:NOC) today announced the delivery of Combat
Electromagnetic Environment Simulator (CEESIM) systems and a Signal
Measurement System (SMS) to Aselsan, the Turkish high technology
defense electronics company based in Ankara.

In three separate contract awards, Northrop Grumman was selected to
provide a CEESIM, an SMS and a Pulseman Portable CEESIM Simulator to
Aselsan's Radar, Electronic Warfare and Intelligence Systems Division
to support various electronic warfare (EW)-related programs within
Turkey. Aselsan provides EW equipment for use on ground-based, naval,
fixed and rotary-wing platforms.

"Together, CEESIM and SMS offer a complete end-to-end electronic
warfare testing solution by providing Aselsan the ability to generate a
highly realistic simulated environment while measuring how well the EW
equipment operates within that environment," said Joe Downie, president
of Northrop Grumman's Amherst Systems business unit.

"The Northrop Grumman CEESIM system is the most advanced radio
frequency (RF) simulator on the market today," noted Downie. CEESIM
generates complex dynamic electromagnetic environments that allow users
to test and evaluate the performance of advanced electronic warfare
systems including radar warning receivers, electronic countermeasure
systems and signal intelligence systems. CEESIM is fully reprogrammable
and is able to simulate EW/radar signals and communication signals.

The Signal Measurement System provides real-time RF measurement and
analysis of threat emitters and corresponding system-under-test jammer
responses for hardware-in-the-loop, installed system, and open-air
training range applications.

The CEESIM and SMS systems were delivered in early spring 2011,
followed by the delivery of the portable version of CEESIM in
September, bringing to seven the total installed base of RF simulators
in Turkey.
