Raytheon, the chief systems integrator for the U.S. Navy's future Zumwalt-class destroyer, reports continued progress in building the ship.

"Progress on milestones continues for the three ships of the class, in labs, at test facilities and dockside at the shipyard -- it's an exciting and rewarding time for the program," said Raytheon's Kevin Peppe, vice president of Integrated Defense Systems' Seapower Capability Systems business area. "The collaboration between industry and the Navy has been outstanding, all moving forward with a common goal -- to bring this transformational ship class to life."

The Zumwalt-class destroyer (DDG 1000) will be 600 feet long and 80.7 feet in the beam. The first, being constructed by Bath Iron Works in Maine, is 90 percent complete. Two additional vessels are also under construction.

Raytheon said recent program milestones include the successful Test Readiness Review of the ship's computing software, release 7, which involved 550,000 lines of code built on a base of more than six million lines of code.

Also significant, the company said, was the production, delivery and integration of the ship's AN/SPY-3 Multi-Function Radar, which tracked air targets during testing using its various search and track modes.
