DDG 1000 Zumwalt-Class Destroyer Program Continues to Progress

The DDG 1000 Zumwalt-class destroyer program continues to progress, meeting key program milestones on the path to Initial Operational Capability (IOC).

As the prime mission systems integrator for the DDG 1000 ship class, Raytheon provides the multi-mission, integrated combat system capability for the program. Raytheon’s recent program milestones have advanced critical mission systems of the next-generation, multi-mission destroyer, from the radar and combat system, to onboard systems integration and crew training.

“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.”

Recent milestones include:

• Successful Test Readiness Review of Total Ship Computing Environment software, release 7. The 550,000 software lines of code – developed, integrated, tested, and delivered – build on the TSCE baseline of more than six million lines of code, and represent the first formal delivery to the ship that includes the combat system software as well as hull, mechanical, and electrical ship control functionality.
• A production AN/SPY-3 Multi-Function Radar successfully tracked air targets for the first time at Wallops Island, VA. The SPY-3 array, receiver/exciter and signal/data processor were controlled by the combat system of the Self Defense Test Ship, exercising various search and track modes, including the new volume search. The radar tracked targets of opportunity and displayed targets and data on the DDG 1000 Common Display System.
• Completion of the third session of instructor-led ship control systems training with members of the DDG 1000 pre-commissioning crew in Bath, Maine. More than 55 sailors have been trained on ship control systems to date; 85 sailors have attended TSCE operations training. Crew training continues, most recently with a session at Raytheon’s Portsmouth, R.I. facility – in the company’s Ship Mission Center, a realistic replica of the crew’s command center.
• Onsite at the shipyard, Raytheon’s Ship Integration and Test team of experts continue to support ongoing installation, integration and test in-line with construction progress to meet Hull Mechanical & Electrical milestones and prepare for ship activation.

Since inception, Raytheon has delivered seven software releases totaling more than 6.5M software lines of code and containing less than 1 defect per 10,000 lines of code, well less than industry standard. This is a testament to the design and development approaches employed, which mitigate risks and mature technologies through phased and incremental testing.

The first ship, the future USS Zumwalt (DDG 1000), is now more than 90 percent complete at the Bath Iron Works shipyard, Bath, Maine, and is supported by Raytheon’s Ship Integration and Test team onsite for ongoing system integration and testing. DDG 1001 and DDG 1002, also under construction at Bath, are now 78 and 8 percent complete respectively.
