5 steps to promote interoperability in military communication systems

‍

In August 2005, during Hurricane Katrina in the US, emergency responders and national leaders struggled to react effectively due to incompatible military communication systems.

Similar issues were observed during NATO’s 2023 Coalition Warrior Interoperability Exercise, where senior military and civilian leaders identified the operational challenges posed by incompatible military communication systems among allied forces.

Additionally, during exercises at the JMRC, the US brigade commander and battalion commanders from other nations struggled with differing interpretations of a tactical task like "seize”, leading to operational friction.

As military operations grow increasingly complex across multiple domains, the need for seamless communication among forces has never been more critical. Read on to understand why interoperability serves as the backbone for coordination and military communication systems.

Why interoperability is critical in modern military communication systems

After the collapse of the World Trade Center towers in 2001, the lack of radio interoperability between New York City's police and fire departments led to tragic consequences. Police officers were ordered to evacuate, but fire and rescue personnel did not receive the same warning, resulting in several deaths.

Interoperability is the ability of diverse systems, platforms, and forces to seamlessly communicate and collaborate, regardless of their origin or design. It ensures that personnel, equipment, and technology from different branches or allied forces can operate together effectively, even under challenging operational conditions.

Key benefits

1. Enhanced coordination during joint missions

Bridge the gap between disparate forces, enabling better synchronization during joint missions. Effective communication protocols reduce risks of miscoordination.

For example, during multinational decisive action training environments, units often experience delays due to poor airspace and ground operation coordination. The support cells request unnecessary clearances or fail to pre-clear areas for artillery and rotary-wing positions.

Compatible military communication systems and military chat platforms can eliminate such procedural gaps, ensuring that land, air, and naval units can exchange critical updates without delays.

2. Reduced response times during critical operations

Streamline communication between units, minimizing delays in relaying mission-critical information. Faster coordination results in quicker decision-making, improving outcomes in high-stakes scenarios.

Incompatible military communication systems force multinational units to redistribute equipment and personnel to share information effectively.

A lack of standardized reporting systems delays operational updates and impedes real-time situational awareness.

The Gulf War highlighted the value of timely communication, with satellite systems ensuring swift coordination and reducing delays.

3. Improved situational awareness through real-time data sharing

Share intelligence and operational data in real time. Enable commanders to make informed decisions on tracking enemy movements and assessing battlefield conditions.

However, over-classification of intelligence data limits effective sharing between US and multinational units in joint intelligence environments.

Integrated command and control systems enable military forces to share real-time intelligence, ensuring situational awareness across all units. This was critical in NATO-led operations in Afghanistan.

Impact of interoperability

For military operations spanning multiple domains – land, sea, air, cyber, and space, interoperability ensures seamless integration of systems and forces. It helps provide:

A comprehensive view of available assets: Understand the resources across all domains for strategic planning.
A unified response to global threats: Ensure coordinated action against shared challenges.

During multinational exercises, differences in doctrinal terminology, such as the US’ "zone reconnaissance" versus NATO’s "area search," can create confusion and misalign task execution with the commander's intent. Interoperable military communication systems ensure consistent communication, reducing misunderstandings.

Challenges in achieving interoperability in military communication systems

After the destruction of Hurricane Katrina in 2005, emergency personnel used written messages dropped from helicopters due to the complete breakdown of radio systems. A lack of resilience in communication systems can cripple emergency response efforts.

However, military operations demand seamless communication across forces, but achieving interoperability comes with significant challenges:

1. Technological disparities

Legacy systems struggle to integrate with modern platforms. For example, older radio networks may not align with advanced digital systems, leading to delays during joint missions.

Inadequate infrastructure in remote areas exacerbates technological challenges.

2. Lack of standardization

Without a unified standard, forces rely on fragmented systems that hinder coordination.

For example, variations in protocols, encryption algorithms and communication formats between allied forces result in fragmented systems that delay real-time decision-making and create operational inefficiencies.

3. Cybersecurity concerns

Open communication channels increase vulnerabilities, exposing systems to data breaches and unauthorized access. To secure data exchange and protect classified information, you need a unified encrypted messaging platform.

4. Cultural and operational differences

Disparities in cultural differences lead to misunderstandings and inefficiencies during joint missions.

For example, varying protocols for reporting can delay critical actions. Differences in terminology and operational approaches can also lead to miscommunication.

Core components of an interoperable military communication system

Effective military communication systems ensure forces can operate cohesively across domains and nations. Here are the essential components of an interoperable military communication system:

1. Unified communication frameworks

Ensure all forces across nations, branches, and domains operate on a common platform. By integrating diverse communication systems, you can collaborate effectively.

For example, NATO's Federated Mission Networking (FMN) initiative aims to standardize platforms and ensure interoperability among allied forces during joint operations.

By establishing unified communication standards, emergency responders can share critical information in real-time, reducing errors during incident recovery.

2. Secure and encrypted channels

Proprietary systems hinder secure communication due to compatibility issues.

Implementing robust encryption protocols can help protect classified data during joint missions. Adopting open standards and compatible equipment helps overcome limitations, ensuring secure data exchange.

For example, Rocket.Chat’s air-gapped communication suite ensures data confidentiality in classified networks like NIPRNet.

3. Real-time data sharing

Sharing intelligence promptly across domains enables quick decision-making and strengthens mission outcomes.

Tools, such as Oracle Data Integrator (ODI), Apache NIFI, Talend, and so on, integrate live feeds and operational data to ensure forces stay informed and synchronized.

4. Scalability for multi-domain operations

Scalable systems ensure uninterrupted communication across diverse operational landscapes.

Interoperable platforms, tested in NATO’s CWIX, showcased the ability to enhance readiness for evolving mission requirements. These frameworks enable seamless communication across allied forces.

Additionally, the ESSOR project enabled cross-border communication among European armed forces.

5. Redundancy and resilience

Backup communication systems ensure operational continuity during disruptions, natural disasters, and infrastructure failures.

Even if your primary networks fail, you can collaborate securely via secondary and tertiary communication pathways.

5 steps to achieve interoperability in military communication systems

Achieving interoperability in military communication systems requires a strategic approach that addresses technical, operational, and security challenges.

The following five steps enable you to enhance collaboration and optimize mission readiness:

1. Conduct comprehensive assessments

Evaluate current communication systems to pinpoint compatibility gaps and performance issues. Regular assessments help ensure your systems’ readiness for multi-domain operations.

The European Secure Software-defined Radio (ESSOR) project achieved a significant milestone in March 2022 by successfully testing interoperability among radios from different European manufacturers.

With ESSOR, armies from different member states can communicate on the battlefield using their own radios, breaking the old paradigm of radios from different manufacturers not being able to exchange voice communication or data.

2. Adopt standardized protocols

The Public Safety Architecture Framework (PSAF) provides a structured approach for emergency responders to understand the technical requirements for interoperable systems. It emphasizes the importance of standardization, ensuring seamless communication and coordination.

Similarly, military forces can benefit from globally recognized protocols like NATO Federated Mission Networking (FMN), which establish unified communication standards.

Adopting such protocols enables effective collaboration between allied forces and minimizes delays.
