NATO C2 Communications Built for Allied Interoperability

One platform to connect every radio, network, and operator across the Alliance

C2 Comms for NATO Countries

NATO fights as one force. Its communications must work the same way.

REDCOM Sigma connects disparate Allied radio systems, IP networks, SATCOM, MANET, PTT applications, and operator devices through one unified C2 platform. We don’t lock customers into a proprietary ecosystem, and there’s no need to replace existing equipment.

Built, Tested, and Ready to Deploy

REDCOM demonstrated Sigma XRI-400 at NATO CWIX 2024 using NATO’s operational test infrastructure. The demonstration connected IP, 5G, VHF, UHF, RTP, and SIP-based systems, proving Sigma’s ability to bridge different communications technologies in a coalition environment. NATO uses CWIX to test and de-risk C2 systems before they are needed in live operations.

CWIX Demonstrated

Evaluated during NATO’s premier annual interoperability exercise at the Joint Force Training Centre in Bydgoszcz, Poland.

JITC Tested

REDCOM Sigma has completed cybersecurity and interoperability testing through the Joint Interoperability Test Command.

Operationally Proven

Sigma has been selected for tactical network modernization programs supporting the U.S. Army and U.S. Air Force and is deployed across military and government environments.

Available Today

Sigma is a deployable, commercial-off-the-shelf platform. Allied forces do not need to wait for a developmental program before addressing current interoperability gaps.

REDCOM Closes the Allied Communications Gap

NATO’s 32 member nations bring different radios, waveforms, networks, procurement cycles, and modernization timelines to the fight. REDCOM Sigma closes that gap by connecting the systems nations already field while providing a flexible path toward future NATO requirements.

Lighter, Faster, More Connected

Built for Every Allied Deployment

REDCOM builds tactical communications products around the real needs of the warfighter: mobility, simplicity, resilience, and interoperability. From radio bridging and command-post control to PTT on the devices operators already carry, every REDCOM solution works together to deliver one connected C2 environment across the mission.

REDCOM Sigma XRI

Sigma XRI connects disparate radio nets, IP endpoints, SATCOM, and MANET talk groups through a compact, purpose-built platform. Deploy it in a pack, mount it in a vehicle, add it to an existing tactical computing system, or install the XRI-PCIe card in a compatible computer or server.

REDCOM STRIKE

STRIKE is an entire command post in one ruggedized laptop. It supports radios, ATAK devices, SATCOM, MANET, and 4G/5G connections while providing the computing power to run additional mission applications, including a TAK server.

Sigma Client

Sigma Client extends interoperable communications to Windows, Android, and ATAK devices. Operators can monitor multiple channels, communicate across radio and IP networks, establish talk groups, stream live video, and coordinate without carrying another dedicated radio interface.

Sigma C2 Console

The browser-based Sigma C2 Console gives operators a live view of the tactical communications environment. Radio nets, talk groups, SIP endpoints, and other connections can be monitored and patched together through a simple drag-and-drop interface.

Frequently Asked Questions

Get clear answers to common questions about NATO tactical communications, Allied interoperability, and how REDCOM Sigma connects disparate systems at the tactical edge.

What is NATO tactical communications interoperability?

NATO tactical communications interoperability is the ability of Allied and partner forces to communicate and exchange information across different national radio systems, networks, applications, and command structures. It allows multinational forces to coordinate as one operational element even when they use equipment from different manufacturers.

Does REDCOM Sigma require NATO nations to replace their radios?

No. Sigma is designed to connect existing and next-generation communications equipment. It is agnostic to radio manufacturer, waveform, encryption, frequency, and transport path, allowing nations to retain fielded equipment while improving coalition interoperability.

Is REDCOM Sigma aligned with NATO’s Federated Mission Networking framework?

Yes. REDCOM Sigma is designed to align with FMN’s interoperability goals and evolving Spiral specifications by connecting disparate Allied radios, networks, and applications through a standards-based, vendor-agnostic C2 platform. FMN is a framework, not a certification program, so Sigma is not described as “FMN certified” or “approved.” Instead, its alignment is shown through its design and interoperability testing at NATO CWIX and other exercises.

Can REDCOM Sigma operate in DDIL environments?

Yes. Sigma can operate as a standalone C2 platform without continuous cloud access, higher-echelon infrastructure, or a persistent SATCOM connection. This allows units to maintain local communications when primary network paths are disrupted.

Where can REDCOM Sigma be deployed?

Sigma can run on REDCOM purpose-built hardware, third-party tactical computing platforms, compatible servers, virtualized infrastructure, and cloud environments.

Has REDCOM demonstrated interoperability with NATO?

Yes. REDCOM demonstrated Sigma at NATO CWIX, where we connected multiple IP, radio, and cellular communications technologies using NATO test infrastructure.
