Inmarsat Government has received a follow-on contract worth up to $578 million to provide satcom services to the Navy Military Sealift Command over a 10-year period. The  indefinite-delivery, indefinite quantity (IDIQ) contract announced Aug. 17 is a follow-on for the Next Generation Wideband (NGW) contract.

Defense Information Systems Agency (DISA) is the contracting authority.

Inmarsat has served the MSC for the past 10 years. The operator will maintain and operate commercial communications infrastructure, which includes satellite systems, teleport services and terrestrial services.

It will also upgrade the primary afloat network from Ku-band to the Global Xpress (GX) Ka-band system, paired with Inmarsat Elera’s enhanced L-band Airborne Intelligence, Surveillance and Reconnaissance (LAISR) service to provide a global back-up network.

“Inmarsat Government is very proud to have delivered robust, highly available, global satellite communications solutions to MSC over the last decade. We look forward to providing that same excellent service and a seamless transition as we deliver highly reliable commercial satellite communications solutions worldwide. Our team is committed to providing MSC with significant enhancements in satcom managed services including the coverage, reliability, resiliency and throughput, all managed end-to-end,” commented Susan Miller, CEO and president of Inmarsat Government.
