The US Navy has awarded a combined contract worth $2.5bn to six companies to install command, control, communications, computer, intelligence, surveillance and reconnaissance (C4ISR) and supporting systems globally.

The Naval Information Warfare Systems Command (NAVWAR) is the contracting activity for the indefinite-delivery, indefinite-quantity, multiple-award contract.

Huntington Ingalls Industries’ (HII) Technical Solutions division is among the six awardees. Other companies to have won a position on the contract include General Dynamics Information Technology, MC Dean, Prism Maritime, Serco, and VT Milcom.

Contract work will include decommissioning and modernisation of existing platforms, as well as installation design and installation of integrated C4ISR systems, programme and project management, engineering design, and industrial work.

In addition, the companies will be required to provide troubleshooting, operational verification, end-user training to support NAVWAR C4ISR maintenance, modernisation, and new system installation.

All selected companies will be able to compete for task orders during the ordering period, the US Department of Defence stated.

The contract will have a base period of five years and an option for extension for an additional five years.

Set to be completed by July 2024, the contract work will be performed at multiple locations across the world.

HII Technical Solutions Fleet Support group president Brad Mason said: “We are excited about this opportunity to continue supporting the Navy’s C4ISR programmes.

“Our highly skilled engineers and technicians have years of experience with installing and modernising these specialised and important warfighting systems. We are proud to support our service men and women defending our nation.”

In August last year, Science Applications International Corp (SAIC) was awarded a contract to produce and deliver integrated C4ISR, networks and support equipment for the US Navy.
