CHARLOTTESVILLE, Va., June 25, 2004 (PRIMEZONE) -- Northrop Grumman Corporation's (NYSE:NOC) Sperry Marine business unit has introduced an embedded training system designed to support onboard training for ships equipped with the Sperry Marine integrated bridge system.

The Integrated Bridge System Trainer (IBS-T) is an embedded simulator system that runs on the ship's installed equipment to provide realistic training for the ship's navigators and bridge watch team in all aspects of navigation, seamanship and ship handling, as well as navigation planning, watch briefings for port entries and departures and other planned piloting evolutions. Sperry Marine developed it in conjunction with Computer Sciences Corporation and Buffalo Computer Graphics.

The IBS-T can be used to run a wide range of scripted simulations on the ship's integrated bridge system, including radar displays, naval electronic chart display and information system and steering/control displays. Visual images of the scenario are projected onto a large screen at the front of the bridge for enhanced realism. Training can be conducted in port or at sea.

The IBS-T can be easily retrofitted on any of the more than 100 U.S. Navy ships and submarines currently equipped with the Sperry Marine IBS. It is also a planned capability for future Sperry Marine IBS installations and upgrades for CVN 68-, DDG 51- and CG 47-class ships. A portable version will be available for SSN 688-class submarines. The IBS-T will provide standardized training throughout the fleet, using the actual equipment installed on the ships.
