Tata Advanced Systems Limited (TASL), in partnership with Spanish engineering major Indra, has successfully developed and commissioned a state-of-the-art 3D Air Surveillance Radar (3D-ASR) for the Indian Navy. The radar, designated Lanza-N, was installed aboard an Indian Navy warship following rigorous sea trials.
This marks the first time such a next-generation naval surveillance radar has been produced and integrated in India, with TASL becoming the first domestic company to demonstrate this capability. Company officials highlighted that the achievement represents a major milestone in India’s quest for defence self-reliance, featuring significant localisation in assembly and system integration.
The radar was tested against a variety of aerial and naval platforms, proving its ability to detect drones, supersonic fighter jets, anti-radiation missiles, and surface vessels with high accuracy. Officials said the system has been seamlessly integrated with the warship’s combat and surveillance architecture.
To sustain production, TASL has established a dedicated radar assembly, integration, and testing facility at its Karnataka plant, which will accelerate future deliveries.
Sukaran Singh, CEO and MD of TASL, said the collaboration reflects a long-term commitment to building India’s radar manufacturing ecosystem. “By leveraging local supply chains and technical expertise, we are developing advanced defence technologies that strengthen India’s maritime capabilities,” he noted.
Ana Buendia, Head of Indra’s Naval Business Unit, underlined that the project goes beyond radar supply. “We have worked with TASL to establish a radar factory in Bengaluru, enabling faster production and closer support for the Indian Navy,” she said.
The Lanza-N radar, one of the most advanced long-range three-dimensional tactical surveillance systems, is being deployed outside Spain for the first time. Its induction marks a critical step in enhancing the Indian Navy’s maritime domain awareness and operational readiness.
