The Defence Research and Development Organisation's (DRDO) Defence Electronics Applications Laboratory (DEAL) has made significant strides in promoting interoperability between the Army, Navy, and Air Force radios. The laboratory has developed the new Indian Radio Software Architecture (IRSA) 2.0 standard, designed to enable seamless communication across services with improved technology and communication needs.
IRSA 2.0 builds on the success of IRSA 1.0, which was released in October this year. The original standard marked India's first software architecture standard for its military Software Defined Radios (SDR). The DRDO and Integrated Defence Staff (IDS) released IRSA 1.0 on October 6, 2025, which defines common interfaces, application programming interfaces, execution environments, and mechanisms for waveform portability across radio hardware.
The development of IRSA 2.0 is a result of a tri-service effort, with the DRDO's DEAL factoring in the requirements of the Army, Navy, and Air Force. The standard is set to be rolled out imminently and is expected to promote radio interoperability for the forces. The value of such a standard lies in enabling radio interoperability at the software-architecture level, rather than designing new radios for each of the Services.

Explore Carbon Fiber →Software-defined radios are particularly well-placed to exploit this kind of standardisation, as their capabilities are defined more by the software and waveforms that run on them rather than the underlying radio hardware. IRSA creates a framework that allows for radio certification and conformance to a common standard, as well as waveform portability. The DRDO has stated that the architecture is designed to be evolutionary and accommodate future technology and communication needs.
A common standard implies that domestic industry can build different radio products that meet the national standard. At the same time, the military can retain greater control over the software environment and certification than might be possible otherwise. Modern platforms such as fighter aircraft, warships, formations, and unmanned systems can carry a range of different radios and communication systems. However, if the systems are not interoperable, the ability to operate effectively is undermined.
In addition to its national security benefits, IRSA also has industrial importance. The original DRDO standard was developed with the tri-service, industry, academia, and research organisations, with the goal of fostering India's domestic SDR industry. The standard also aims to enable India to export IRSA-conformant radios.
The development of IRSA 2.0 is a significant milestone in India's journey towards promoting interoperability between its military services. The standard has the potential to revolutionise the way India's armed forces communicate, and its impact will be felt across the country's defence ecosystem. As the DRDO continues to develop and refine IRSA 2.0, it is clear that the future of India's military communications is looking brighter than ever before.
