for armed forces, police, special forces and security services. The
exhibition is at Riocentro, Rio de Janeiro 12-15 April. The Northrop Grumman
exhibit is at location B-40, Hall 4 and N-56b in Hall 3.

"We have a well established relationship with our customers Brazil and
our objective is to continue to work closely with them to provide long-term
capability solutions and help enhance national security," said Nolasco
DaCunha, vice president, Northrop Grumman Sperry Marine. "Our expertise in
the design, development and production of navigation and control systems,
radar systems and airborne surveillance is well matched to meeting the
region's growing defence and security requirements."

Northrop Grumman's Sperry Marine business unit will be displaying a range
of its latest generation marine navigation, ship control and coastal
surveillance radar solutions including the VisionMaster FT Integrated Bridge
and Platform Management System. The VisionMaster FT Total Watch
multi-function workstation will be on display including the warship
electronic chart display and information system (ECDIS). VisionMaster FT
provides a highly integrated fully networked suite of marine radar and
electronic charting systems designed to form the backbone of the modern
ship's integrated bridge.

Other capabilities which will be highlighted are the maritime domain
awareness coastal surveillance system, the SeaGuard XBCR x-band coherent
radar for small target detection and situational awareness, and the LFK-100
fibre optic gyrocompass, a solid-state, fully electronic, digital gyrocompass
system for integrated bridges.

AN/APG-68(V)9 mechanically scanned array radar for the F-16 multi-role
fighter aircraft.

Northrop Grumman's airborne surveillance capability will be highlighted
with a model of the combat-proven RQ-4 Global Hawk unmanned aircraft. Most
recently, Global Hawk has been providing vital aerial surveillance in support
of the earthquake and tsunami relief efforts in Japan, further demonstrating
its ability to provide vital support to national security and humanitarian
relief operations. Additionally, Global Hawk is supporting operations in
Afghanistan and Libya, where it is performing more sorties at a faster rate
and covering a wider than earlier test and evaluation results predicted.

The company's air traffic management ground to-air communications systems
