Indian Air Force Prolongs TRS-2245 Radar Service Life with Strategic Spares Procurement

The Indian Air Force (IAF) has taken a significant step in maintaining its legacy TRS-2245 Master-T long-range surveillance radar fleet by procuring essential spares. This move underscores the IAF's commitment to extending the service life of its ageing radar systems, ensuring continued air-defence network coverage.

A recent tender floated by the IAF for TRS-2245 spares indicates that the procurement is focused on supporting the radar's existing electronic, power-management, and subsystems. The tender lists several critical components, including the TRMIC card, circuit breaker, flowmeter, valve modulation box, CPU card, valve, and contactor. Notably, the list does not include major components, suggesting that the IAF is not planning a major upgrade.

The IAF's continued procurement of TRS-2245 components is not an isolated incident. The service has sought spares for the radar through earlier tenders, including procurement activity in 2025 and 2022. This indicates that the IAF recognizes the importance of maintaining older air-defence assets while inducting newer systems.

The TRS-2245 Master-T is a tactical 3D long-range air-surveillance radar originally developed by Thomson-CSF (now Thales). Open-source technical references describe it as a mobile S-band radar, suited for long-range surveillance and tracking, including in heavily contested electronic environments. The radar provides 360-degree coverage with a maximum detection range of around 440 km, while a specialized channel can support tracking of ballistic targets at ranges of up to 350 km.

India acquired the Master-T system in the early 2000s, with the radar entering IAF service around 2004-05. The continued presence of the TRS-2245 in procurement records over two decades later highlights the importance of maintaining older air-defence assets. For the IAF, replacing a radar is not simply a matter of purchasing a new sensor. A command-and-control existing architecture, communications, operator training, spares, and infrastructure all have to be considered.

The IAF's decision to prolong the TRS-2245 radar service life through strategic spares procurement demonstrates its commitment to maximizing the value of its existing assets. By continuing to support the ageing radar fleet, the IAF can ensure continued air-defence network coverage and maintain its air-surveillance capabilities.

The IAF's approach to maintaining its air-defence assets is a testament to its ability to adapt and evolve in a rapidly changing security environment. By prolonging the service life of its TRS-2245 radar, the IAF can continue to provide effective air-surveillance capabilities, supporting its national security objectives.

In conclusion, the Indian Air Force's decision to prolong the TRS-2245 radar service life through strategic spares procurement is a significant step in maintaining its air-defence capabilities. By continuing to support its ageing radar fleet, the IAF can ensure continued air-defence network coverage and maintain its air-surveillance capabilities, supporting its national security objectives.
