TASL Makes Advanced 3D Air Surveillance Radars under ToT from Indra For Indian Navy

Tata Advanced Systems Limited, in collaboration with Indra, successfully delivered and commissioned the first 3D-ASR, Lanza-N, aboard an Indian Navy warship. With this, Tata Advanced Systems becomes the first Indian company to demonstrate the capability to build and integrate next-generation naval surveillance radar systems. This achievement also marks a key milestone in India’s pursuit of defence self-reliance, with significant localisation in system integration and assembly.

The radar has been seamlessly integrated with all systems of this Indian Navy warship. Its acceptance and induction followed rigorous sea trials, during which various naval and aerial platforms were deployed to test performance across a range of radar cross-sections. To support ongoing production, a radar assembly, integration and testing facility has already been established at Tata Advanced Systems’ facility in Karnataka, which will accelerate deliveries.

Chief executive officer & managing director, Tata Advanced Systems, Sukaran Singh said, “Our collaboration with Indra reflects a shared commitment to strengthening radar manufacturing capabilities in India. By leveraging on-ground synergies, technical expertise, and a robust local supply chain, we are building a strong ecosystem for advanced defence technologies.”

Head of Indra’s Naval Business Unit Ana Buendía said, “This project goes far beyond the delivery and deployment of radars for a large number of vessels. It has also enabled us to establish a significant collaboration with Tata Advanced Systems, with whom we have worked to establish a radar factory in Bengaluru. This now provides us with local support to produce systems more efficiently and offer closer service to the client.”

Indra’s Lanza-N is one of the most advanced long-range, three-dimensional tactical surveillance system capable of detecting friendly and hostile air and surface targets within a particular coverage space. The radar is highly effective in detecting various types of drones, supersonic fighters, and anti-radiation missiles as well as all types of naval platforms. This is the first time that a Lanza-N radar would be operational outside Spain.
