Raytheon has secured a contract extension of $255m to engineer the mission system equipment for the US Navy’s third Zumwalt-class (DDG 1000) guided-missile destroyer, the USS Lyndon B Johnson (DDG-1002).

The latest contract comes with options, which if exercised can increase the value of the contract to a sum of $349m.

Work under the contract will be carried out by the company across its facilities in the US and Canada.

Around 40% of the work is to be done in Portsmouth, Rhode Island; 25% in Andover, Massachusetts; 18% in Marlboro, Massachusetts; 5% in Charlottesville, Virginia, another 5% in McKinney, Texas; 5% in Moorestown, New Jersey and last 2% to be done in Ontario, Canada.

"The third and the last Zumwalt destroyer will be incorporated with Raytheon engineered technologies."

The contract is expected to be completed by October 2019.

The third and the last Zumwalt destroyer will be incorporated with Raytheon engineered technologies, such as the total ship computing environment, electronic modular enclosure, integrated undersea warfare system, and the MK57 vertical launching system.

Additionally, the destroyer will feature an advanced gun system and an integrated power system.

Raytheon was previously contracted to deliver engineering services for Zumalt-class destroyers.

The company will serve as the prime mission systems equipment integrator for all electronic and combat systems for the programme.

The Naval Sea Systems Command, Washington, District Of Columbia will serve as the contracting activity.

In December, the US Navy’s first Zumwalt-class (DDG 1000) destroyer sailed out to sea from shipbuilder General Dynamics Bath Iron Works for the first time to begin its maiden sea trials.
