IN Brief:
- Viasat subsidiary Inmarsat Government has received an initial $42 million MECS2 task order for US Marine Corps connectivity.
- The seven-year contract has a ceiling of up to $307 million and combines satellite capacity with terrestrial network services.
- Connectivity will span L, Ku, and Ka bands and multiple orbital architectures, supported by network and cybersecurity operations.
Viasat has received an initial $42 million task order to provide managed multi-orbit satellite communications for the US Marine Corps under a seven-year contract with a ceiling of up to $307 million.
The Marine Enterprise Commercial Satcom Satellite Services contract, known as MECS2, was awarded through Viasat subsidiary Inmarsat Government by the US Space Force Commercial Satellite Communications Office. It establishes a framework through which the Marine Corps can obtain global satellite connectivity, terrestrial transport, network management, terminal support, and associated cybersecurity services.
Viasat says the service will combine L, Ku, and Ka-band satellite capacity using spacecraft and networks supplied by the company and partner operators. The architecture is intended to span several orbital regimes rather than tying deployed users to one constellation or frequency band.
Different satellite layers offer different trade-offs in coverage, latency, capacity, terminal requirements, and resilience. Geostationary spacecraft provide broad and established service areas, while low and medium Earth orbit networks introduce other options for latency and coverage. Combining them under a managed architecture allows traffic to be routed according to operational availability without requiring individual users to manage each commercial network independently.
The initial task order includes access to Viasat’s global Ka-band infrastructure and ViaSat-3 capacity alongside partner services. The company will also provide terrestrial connectivity carrying data from the tactical edge back towards the Marine Corps Enterprise Network.
That makes MECS2 a network integration requirement as well as a purchase of satellite capacity. Spacecraft, gateways, terrestrial links, user terminals, network-management systems, and security controls all have to function as one service from the perspective of the deployed unit.
Operational support forms another part of the package. Viasat will provide continuous network and security operations centre coverage, including bandwidth management, terminal inventory management, performance monitoring, and cybersecurity functions.
Those services become more important as the number of available communications paths increases. A multi-orbit architecture offers resilience only if the network can identify degraded links, allocate capacity, manage terminal configurations, and shift traffic without creating unacceptable interruption or new security weaknesses.
The Marine Corps presents a particularly demanding communications environment because formations operate across ships, aircraft, land units, and temporary expeditionary sites. Terminals may move frequently, work with limited local technical support, and have to maintain connectivity across widely dispersed units.
A managed service moves some of that complexity away from the deployed user and towards the network provider. Viasat must therefore manage not only bandwidth but also the interfaces between commercial satellite systems, terrestrial infrastructure, user equipment, and Marine Corps networks.
That model reflects a broader shift in military satellite communications. Defence users are increasingly combining sovereign military systems with commercial capacity instead of treating the two as separate communications environments. Commercial networks can provide bandwidth, geographic reach, and additional routing options, while military systems retain capabilities and controls tailored to defence requirements.
The integration challenge is maintaining consistent management and security across those layers. Commercial constellations differ in terminal design, coverage, control systems, and commercial operating models, while military users expect communications to remain available under conditions that can include interference, cyber attack, damaged infrastructure, or rapidly changing deployments.
Viasat enters MECS2 with an existing government communications business rather than as a new defence supplier. Inmarsat Government has supplied managed satellite services to US agencies for years, while the wider Viasat group combines spacecraft, terminals, tactical networking, and terrestrial infrastructure.
The use of the Space Force’s commercial satellite office as the contracting route also allows demand to be organised across established government acquisition mechanisms while Marine Corps users place task orders against their own requirements.
The $307 million figure is a ceiling rather than committed revenue. The initial $42 million order represents work actually placed at this stage, with further value dependent on Marine Corps use of the seven-year contract.
Future task orders will therefore provide the clearest measure of programme scale. The technical framework is already defined around several bands and orbital layers, integrated with terrestrial transport, terminal support, and continuous network and security operations. The remaining question is how extensively that architecture is used as the Marines expand distributed and expeditionary communications.
