TEWKSBURY, Mass., Sept. 8, 2008 /PRNewswire/ -- Raytheon Company (NYSE: RTN) achieved another in a series of milestones for the Zumwalt-class destroyer program with the successful completion of the ship's Total Ship Computing Environment (TSCE) software Release 5 critical design review.

Zumwalt's TSCE is a modern, open systems architecture that provides a scalable platform for cost-efficient delivery of new mission capability, while capitalizing on reuse of millions of lines of code from existing Navy programs. The system delivers an unprecedented level of Mission Systems Integration and automation and is a primary driver for the 60 percent reduction in manning for the Zumwalt-class destroyer versus the requirement for today's Arleigh Burke-class destroyers.

"This success is another in our incremental 'build and test' methodology for this program - validating system maturity before advancing to the next development phase," said Raytheon Integrated Defense Systems' (IDS) Ed Geisler, vice president and program manager for the Zumwalt program. "As a result of this critical design review, more than 70 percent of the required Zumwalt software has entered the coding and unit test phase, and the program continues to be within budget and on schedule."

TSCE consists of six releases of software, each version adding new features and robustness to the ship's mission capabilities. Release 5 is composed of 30,000 software requirements that comprise 16 elements, 32 components and 126 software ensembles. This latest release will raise the total number of delivered lines of software code for Zumwalt to 5.9 million.

The Zumwalt-class will be the first in a family of surface combatant ships that provide unmatched capability to the U.S. Navy. The advanced technologies developed for the destroyer can be reused on future and modernized platforms. The benefits of Zumwalt's systems commonality are already being realized by the application of the Dual Band Radar on the new Ford-class aircraft carrier (CVN 78), as well as the application of the TSCE infrastructure for the USS Nimitz (CVN 68) and USS San Antonio (LPD 17) technology refresh efforts. The systems and software engineering approach used on Zumwalt has yielded an architecture that is well suited for capability enhancements to counter emerging threats, while providing affordable new capabilities that address future mission requirements such as sea-based ballistic missile defense.

Raytheon performs software work for the Zumwalt program at a number of IDS mission centers across the country, including IDS Headquarters, Tewksbury, Mass.; Seapower Capability Center, Portsmouth, R.I.; Surveillance and Sensors Center, Sudbury, Mass.; Expeditionary Warfare Center, San Diego, Calif.; as well as several other Raytheon facilities.

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.
