Tata Advanced Systems Ltd. (TASL), in collaboration with Spanish defence technology firm Indra, has delivered India’s first Lanza-N 3D Air Surveillance Radar (3D-ASR) to the Indian Navy. Installed on a frontline warship, the system has successfully completed sea trials and been fully integrated with shipboard command and control platforms. The radar represents a significant stride toward India’s defence self-reliance, enhancing maritime surveillance and early-warning capabilities. With a dedicated assembly and testing facility established in Karnataka, this development underscores India’s ambition to localise advanced defence technologies while boosting operational readiness across naval fleets.
A New Era in Naval Surveillance
The induction of the Lanza-N 3D radar marks a turning point in India’s naval modernisation efforts. Developed by Indra and manufactured under TASL’s leadership, the radar can detect and track a wide spectrum of aerial and surface threats — from drones and supersonic aircraft to anti-radiation missiles and naval vessels. Its design is optimised for maritime environments, allowing consistent performance under challenging conditions such as high humidity, salt corrosion, and extreme coastal temperatures.
Indigenous Manufacturing and Technology Transfer
The project is not merely about deployment but also about building long-term indigenous capacity. TASL has set up a state-of-the-art radar assembly, integration, and testing facility in Karnataka to support future production. This initiative aligns with the government’s Atmanirbhar Bharat programme, reducing dependence on imports for critical defence technology while nurturing a local ecosystem of suppliers, skilled engineers, and advanced electronics.
Deployment and Operational Readiness
The radar has already undergone extensive sea trials, validating its compatibility with onboard systems across multiple platforms. According to defence officials, the system will now be deployed on destroyers, frigates, and aircraft carriers in phased rollouts. By enabling real-time tracking and early warning, the radar strengthens India’s ability to monitor threats across strategic waterways, enhancing situational awareness and improving naval response times.
Strategic and Economic Significance
This delivery offers multiple advantages for India. Strategically, it improves maritime security amid rising geopolitical tensions in the Indian Ocean region. Economically, it positions TASL as a serious player in the global defence radar market while opening doors for future exports. The localisation of advanced systems also creates long-term cost savings in maintenance, spare parts, and lifecycle support.
Challenges and Next Steps
Despite the achievement, challenges remain. Ensuring consistency in local supply chains, maintaining stringent quality standards, and keeping pace with evolving stealth and electronic warfare technologies will require ongoing research and development. Scaling production to cover the Navy’s full operational requirements while balancing cost and delivery timelines will also test TASL’s industrial capacity.
Outlook
The successful delivery of the Lanza-N radar demonstrates how strategic partnerships, combined with local industrial capabilities, can transform India’s defence landscape. With further deployments planned, the Indian Navy is poised to gain a decisive edge in maritime surveillance and threat detection. More broadly, this development reflects India’s steady transition from being a major importer of defence systems to an emerging hub of indigenous innovation and manufacturing.
