Inmarsat Government has been awarded a U.S. Navy Commercial Broadband Satellite Program (CBSP) Satellite Services Contract (CSSC II) for complex and worldwide, end-to-end, commercial satellite communications (SATCOM) services by the Defense Information Systems Agency (DISA) — the ceiling value of the award is $980 million over a 10-year period.

Under the contract, Inmarsat Government will deliver worldwide managed telecommunications services, including satellite capabilities, via Inmarsat Global Xpress Ka-band, as well as C-, Ku- and X-band frequencies, for mobile and fixed satellite services on crewed and uncrewed maritime, airborne and ground platforms. The company will also provide commercial teleport services; backhaul connectivity; monitoring and control; operations; information assurance and cybersecurity.
The CSSC II program is the follow-on to the CSSC contract where Inmarsat Government was the prime contractor, delivering proven, reliable connectivity between the Navy’s global fleet of shipboard terminals and shore-based telecommunications infrastructure.
Under the newly-awarded CSSC II contract, the company will provide end-to-end SATCOM services capable of supporting approximately 400 simultaneous full period, full duplex, simplex and simplex broadcast connections/modems between a designated point of presence and the end user terminal through the means of space and terrestrial connectivity. Solution benefits include:
- Global network infrastructure – A complete, efficient, scalable and resilient in-place solution that is compliant with Information Assurance requirements and includes redundant commercial teleports and a global Multiple Protocol Label Switching (MPLS) terrestrial backhaul network for reach back to designated points of presence.
- Resilient space segment and interoperability with MILSATCOM – Required user terminal data throughput and quality of service requirements to include global Military Ka augmentation and Arctic services on Inmarsat’s forthcoming Highly Elliptical Orbit (HEO) GX10A/B satellites.
- Cybersecurity – Inmarsat Government has a proven track record of providing comprehensive cybersecurity services, including the ability to respond to vulnerabilities and incidents in accordance with the Risk Management Framework, by evaluating the holistic nature of the risk factors, incidents, and mitigation techniques.
Susan Miller, Chief Executive Officer, Inmarsat Government, said, “Inmarsat Government is proud to be selected as the end-to-end SATCOM provider under the U.S. Navy CSSC II contract.
