TEWKSBURY, Mass., March 12, 2008 /PRNewswire/ -- The Zumwalt program's National Team recently achieved a significant program milestone with several key software design reviews for the Zumwalt-class destroyer's Total Ship Computing Environment (TSCE), validating the maturity of the ship's open- architecture software.

The Zumwalt National Team is led by Raytheon Company (NYSE: RTN) and includes large industry partners such as BAE Systems and Lockheed Martin, as well as a consortium of small businesses. These industry partners work together with the U.S. Navy to ensure the highest level of program performance, technical quality and affordability.

TSCE comprises six releases of software, each adding mission capability and robustness to the ship's computing infrastructure. TSCE's modern, open architecture provides an affordable, cost-efficient platform for the reuse of more than 20 million lines of code from existing Navy programs.

"This is one of the largest, most sophisticated software efforts ever undertaken by Raytheon and the U.S. Navy -- one that will pay dividends in terms of capability and commonality for years to come," said Bob Martin, Raytheon Integrated Defense System's vice president and deputy of Seapower Capability Systems. "Each success matures the software and brings us closer to delivering extraordinary capabilities to the ships and warfighters of the Navy's fleet."

The current release of the TSCE software (Release 5), which adds 5 million delivered lines of code to the Zumwalt baseline, introduces surface warfare, integrated undersea warfare, information operations and general naval operations capabilities to the combat system and also provides the framework to support the ship's engineering control system. In addition, multi-mission engagement support is significantly enhanced with the addition of post-launch missile support for both Evolved SeaSparrow Missile and Standard Missile, as well as the full capabilities of the Close-in-Gun System and Advanced Gun System.

The reviews took place during a series of software technical meetings that included representatives from Raytheon Integrated Defense Systems, members of the Zumwalt national industry team and the U.S. Navy. The reviews included the sixth major software review for the Zumwalt program, an applications preliminary design review for Release 5 of the TSCE software, as well as critical design review of the Release 5 Total Ship Computing Environment Infrastructure. These successful software reviews verified that Raytheon and its teammates remain on schedule and on budget to deliver these critical capabilities to the Navy.

The Zumwalt Total Ship Computing Environment Infrastructure provides an open-architecture shipboard enterprise network allowing seamless integration of all on-board systems. It also gives the Navy increased ability to use standardized software and commercial-off-the-shelf hardware on a fleet-wide basis. TSCEI provides computer support for Zumwalt ship control, maintenance, logistics, training and other deployment functions. This level of integration and automation is unprecedented and is a primary driver for the 60 percent reduction in manning being implemented on the Zumwalt-class destroyer.

Under the Navy's DDG 1000 Detail Design and Integration contract awarded in 2005, Raytheon IDS serves as the prime mission systems equipment integrator for all electronic and combat systems for the Zumwalt-class destroyer program. Working with the Navy and a team of industry leaders, IDS is leading the effort to transform the Navy's ship requirements to reality.
