The Indian Air Force (IAF) is developing a Unified Situational Awareness System (USAS), centred around the indigenous VAYULINK tactical data-link ecosystem, to create a secure, real-time network connecting airborne and ground units.

This initiative reinforces India’s move toward self-reliant defence technologies and addresses critical communication gaps that once led to operational vulnerabilities.

Addressing A Critical Operational Gap

The impetus for developing VAYULINK came after the 2019 accidental downing of an IAF Mi-17 V5, caused by coordination and identification failures. In response, the IAF initiated an in-house R&D program to strengthen friendly force visibility, prevent fratricide, and ensure seamless coordination across armed service branches. The system marks a decisive step toward reducing dependence on imported data-link solutions.

Indigenous And Secure Tactical Data Link

VAYULINK functions as an ad-hoc, encrypted tactical data link, connecting combat aircraft, helicopters, unmanned platforms, and ground units under a unified communication grid. Unlike conventional radio-based systems, it leverages the Indian Regional Navigation Satellite System (IRNSS/NAVIC) to enable jam-proof, uninterrupted data exchange even under degraded signal conditions.

Real-Time Fratricide Prevention And Target Identification

A key purpose of VAYULINK is preventing friendly fire incidents by continuously sharing exact positional data of all friendly formations—airborne, vehicular, or infantry-level—on a common display interface. Pilots can now discern friend from foe even during fast-paced, complex missions in cluttered battle zones, particularly along India’s northern and western borders.

Enhanced Situational Awareness And Decision Support

The USAS powered by VAYULINK integrates feeds from multiple sensors and platforms across the joint battlefield network, offering a single composite picture to commanders. Real-time position, threat, and environmental data enable faster and more informed decision-making, significantly improving operational readiness and mission success rates.

All-Weather And Safety-Enhanced Operations

Beyond combat functions, VAYULINK enhances operational safety by providing live weather updates and terrain data for pilots, ensuring safe navigation in adverse environments. Its collision avoidance feature identifies nearby aircraft positions, reducing the risk of mid-air incidents during formation flying or congested airspace operations.

Multi-Force Applicability And Interoperability

While conceptualised and developed by the IAF, VAYULINK’s compatibility extends to the Indian Army and Navy, reinforcing joint force integration. The Army employs a variant known as the “Trishul Link,” reflecting the common architecture being adopted across services for seamless interconnectivity during joint operations or disaster-response missions.

Overcoming Older System Limitations

Unlike legacy Identification Friend or Foe (IFF) systems limited by radar and line-of-sight constraints, VAYULINK enables beyond-line-of-sight communication, ensuring continuous tracking even in mountainous, forested, or jammed environments. This extends the IAF’s situational coverage deep into the battlefield with minimal reliance on ground radar assets.

Development Progress And Deployment Status

Developed under the leadership of Wing Commander Vishal Mishra, a serving IAF helicopter pilot, VAYULINK was first unveiled at Aero India 2023. Following successful field evaluations, trial deployments in forward bases across the Northern and Western sectors have validated its performance in real-world conditions, including high-altitude and electronic warfare-prone zones.

Atmanirbhar Bharat And Future Inductions

VAYULINK’s hardware and chip-level integration were executed entirely in India, advancing the nation’s Atmanirbharta (self-reliance) vision in critical defence communication technologies. The system has entered the procurement and mass-production phase, with plans for full-scale induction across all IAF and tri-service platforms positioned in forward operational theatres.

Once widely deployed, VAYULINK will form the backbone of India’s secure, indigenous network-centric warfare infrastructure, ensuring information superiority and operational safety in modern multi-domain combat.
