Overview

GCCS-J is a family of joint C2 software fielded across U.S. combatant commands, services and allied headquarters, providing force status, common operational picture and deliberate/crisis-action planning tools. Originally developed in the 1990s to replace the legacy WWMCCS system, it has been sustained and modernized over decades by multiple contractors, with Northrop Grumman among the companies supporting its continued operation and evolution toward more distributed, cloud-based joint C2 architectures.
