Raytheon to upgrade shipboard computers, networking and combat systems aboard Zumwalt-class destroyers

WASHINGTON- US Navy shipboard electronics experts ask Raytheon Technologies Corp. to upgrade computers and computer networking equipment aboard the Navy’s three Zumwalt-class land-attack destroyers (DDG 1000) in a potential $1.7 billion contract announced the last week.

Naval Sea Systems Command officials in Washington announced a $482.7 contract with the Raytheon Missiles & Defense segment in Tewksbury, Mass., for the activation of DDG 1000-class combat systems, as well as the maintenance and modernization of mission systems and the total infrastructure of the ships’ computing environment (TSCEi).

The three Zumwalt-class destroyers are multi-mission stealth ships that focus on land attack, with secondary roles of surface warfare, anti-aircraft warfare, and naval gunfire support. This contract includes options that could increase its value up to 1.7 billion dollars.

The contract includes one-time engineering services supporting the installation, integration, development, testing, remediation, maintenance and modernization of Zumwalt-class destroyer mission systems and mission systems.

The appellation destroyer is somewhat of a misnomer as Zumwalt-class ships are roughly the size of small World War II battleships.

Navy officials have separately reached out to industry to find companies that can help integrate future hypersonic weapons aboard Zumwalt-class destroyers: USS Zumwalt (DDG 1000), USS Michael Monsoor (DDG 1001 ) and USS Lyndon B. Johnson (DDG 1002).

Installing hypersonic weapons aboard these three ships is to be part of the Navy’s Conventional Prompt Strike project to launch attacks against targets around the world in less than an hour. The focus is on attacking high-value or ephemeral targets, with extremely fast hypersonic weapons, which can fly faster than five times the speed of sound.

Zumwalt-class destroyers have Integrated Electric Propulsion Systems (IEPs) that can send electricity from turbo-generators to electric drive motors or weapons, Total Ships Computing Environment Infrastructure (TSCEI ), automated fire-fighting systems and automated pipe rupture isolation. . The class is designed to require a smaller crew and to be less expensive to operate than comparable warships.

The Navy’s Conventional Fast Strike Weapon System platform-specific development and production project focuses on the system of systems architecture; subsystem, component, and test requirements; design analysis and design integration; system integration, verification and validation testing to support initial operational capability.

Under this contract, Raytheon will perform the work in Tewksbury, Mass. ; Portsmouth, RI; San Diego; Nashua, NH; Pascagoula, miss; and Fort Wayne, Ind., and is expected to be completed by April 2023.
