Tata Advanced Systems and Spanish Defence firm Deliver India's First Indigenous Lanza-N 3D Naval Radar

Bengaluru / New Delhi, 11 September 2025 : In a major breakthrough for India’s defence industry, Tata Advanced Systems Ltd (TASL), in partnership with Spanish defence firm Indra, has successfully manufactured, delivered, and commissioned the Lanza-N 3D Air Surveillance Radar (3D-ASR) on an Indian Navy warship. This marks the first time such a system has been built and integrated in India, placing TASL at the forefront of advanced naval radar manufacturing.

What Makes the Lanza-N Radar Special

• Three-Dimensional Long-Range Coverage: The radar provides detection and tracking in range, azimuth, and elevation, enabling early warning against aircraft, drones, missiles, and naval vessels.

• L-Band Operation with Pencil-Beam Scanning: Designed for high accuracy, the radar uses advanced beam-forming techniques and monopulse tracking for precise target location.

• Robust Against Electronic Warfare: Equipped with strong counter-jamming and clutter suppression features, it maintains performance in contested environments.

• High Range Capability: The radar has an instrumented detection range of up to 254 nautical miles, providing extended situational awareness.

• Integrated IFF/SSR: Includes secondary surveillance radar functions with multiple identification modes, allowing clear friend-or-foe classification.

• Rugged Naval Adaptation: Engineered for tropical maritime conditions, it withstands high temperatures, humidity, vibration, and salt exposure.

• Scalable & Modular Design: Suitable for frigates, destroyers, and aircraft carriers, the radar can be configured for different naval platforms.

Production and Localisation

Under a 2020 contract, 23 radars are to be supplied: three fully built in Spain, and 20 more assembled and integrated in India. To support this, TASL has established a dedicated radar assembly, integration, and testing facility in Karnataka. The facility will not only accelerate deliveries but also enable long-term servicing and upgrades.

This makes it the first time the Lanza-N system is operational outside Spain, underscoring India’s growing role in advanced defence manufacturing.

Strategic Significance

• Boost to Atmanirbhar Bharat: By indigenously assembling and integrating next-generation surveillance radars, India moves closer to self-reliance in high-end defence systems.

• Stronger Maritime Shield: Once deployed across multiple classes of warships, the radar will enhance India’s air and surface surveillance envelope in the Indian Ocean Region.

• Technology Transfer Advantage: Local assembly and testing ensure India gains technical know-how, creating a skilled workforce and reducing reliance on foreign suppliers.

• Operational Readiness: Local support ensures faster maintenance, lower lifecycle costs, and greater availability of naval assets.

Expert Views

Sukaran Singh, CEO & MD of TASL, called the achievement a “major leap in India’s ability to produce advanced radars indigenously,” highlighting the role of local supply chains and technical collaboration.

Ana Buendia, Head of Indra’s Naval Business Unit, noted that the project is not limited to radar deliveries. “It has also enabled us to build a radar factory in Bengaluru with TASL, ensuring closer service support for the Indian Navy.”

The successful commissioning of the Lanza-N on an Indian Navy vessel is a powerful signal of India’s determination to build, integrate, and sustain next-generation defence systems at home. With the rest of the radar deliveries scheduled in phases, the Navy is set to gain a decisive surveillance edge in protecting India’s maritime interests.
