Raytheon Missiles & Defense (RMD) has secured a contract to provide engineering and other support services for the US Navy’s Zumwalt-class guided missile destroyers.

Value of the contract is estimated to be $483m and includes additional options across five years.

If all the contract options are exercised, the cumulative value will increase to approximately $1.68bn.

Under the firm-fixed-price contract, the company will support the three Zumwalt-class destroyers’ activation and introduction into the fleet.

RMD will also continue to develop other technology and warfare capabilities for the fleet.

RMD president Wes Kremer said: “This contract underscores our role as a systems integrator, which goes beyond offering customers weapons and radars.

“Our team provides Zumwalt destroyers extensive support, from engineering and cyber protection to software development and upgrades.”

The activation, sustainment and modernisation contract will also include several other support services, such as system upgrade and replacement and configuration management.

In addition, the company will provide design, integration, evaluation, tests, logistics development and other training system support for the warships.

Work is expected to complete by April next year, however, if all the options are exercised the contract will continue through April 2027.

The US Navy’s three Zumwalt-class destroyers are USS Zumwalt (DDG 1000), USS Michael Monsoor (DDG 1001) and USS Lyndon B Johnson (DDG 1002).

As a prime contractor, RMD is responsible for developing mission system and combat system equipment and other sensors and software for the vessels.

The first two warships are already in service, while the third DDG 1002 has recently completed builder’s trials, prior to its commissioning into the Navy.

Last year in December, the Zumwalt-class destroyers successfully achieved initial operational capability. This will be followed by inaugural fleet employment expected later this year.
