The U.S. Air Force awarded Kratos Defense and Security Solutions a $13.9 million modification to a previously issued contract for satellite command and control services.

Specifically, the deal calls for Kratos to provide control system consolidated production and sustainment.

“These services are required to sustain and provide post-production development for the current CCS-C [Command and Control System – Consolidated] system for telemetry, tracking and commanding of current and future military satellite communications satellites,” said a statement issued by the Pentagon on Jan. 2.

“This contract modification exercises an option period for mission activity and maneuver planning, telemetry processing, commanding, orbit and attitude management, resource management, space vehicle and ground system simulation, security, support planning and execution, training and testing. Satellite state-of-health operations include launch, early orbit, on-orbit, anomaly resolution, disposal and backup operations.”

Work will continue through Sept. 30, the end of the federal fiscal year. Kratos will provide the services in Colorado Springs, Colorado, as well as Vandenberg Air Force Base in California. The Military Satellite Communication System Directorate at the Space and Missile Systems Center at Peterson Air Force Base in Colorado awarded the contract.

Kratos (Nasdaq: KTOS) is based in University City and had $669 million in revenue in 2016, up from $657 million in 2015. Revenue figures for 2017 have not yet been released.
