In a major boost to India’s naval air defence capabilities, the Indian Navy has commissioned its first Tata-made Lanza-N 3D Air Surveillance Radar. The radar, a naval variant of Spanish firm Indra’s Lanza 3D system, was built and integrated by Tata Advanced Systems Limited (TASL) under a USD 145-million deal signed in 2020. This marks a significant milestone in India’s defence indigenisation and self-reliance drive.
About the Lanza-N Radar
The Lanza-N radar is among the world’s most advanced long-range air defence and anti-missile radars.
Key Features
- Range: Detects aircraft from 9 km to 474 km
- Altitude coverage: Up to 100,000 feet
- Rotation speed: Completes one full rotation in 10 seconds, ensuring continuous situational awareness
- Adaptation: Specifically modified for high humidity and extreme heat of the Indian Ocean Region
The radar provides early warning against enemy aircraft, drones, and missiles, thereby strengthening India’s maritime security and defence readiness.
The India-Spain Radar Deal
- Year of agreement: 2020
- Value: Approx. USD 145 million
Scope
- 3 radars fully delivered by Indra (Spain)
- 20 additional radars’ core systems provided for local integration by TASL over a decade
- Integration: TASL has set up a dedicated assembly, integration, and testing facility in Karnataka to accelerate production.
- This arrangement ensures technology transfer, localisation, and skill development in India’s defence manufacturing sector.
Indigenous Manufacturing and Sea Trials
- The first radar has been seamlessly integrated with an Indian Navy warship.
- Underwent rigorous sea trials, involving multiple naval and aerial platforms
- Validated performance across different radar cross-sections and threat scenarios
Confirmed compatibility with all ship systems
With this, TASL becomes the first Indian company to build and integrate next-generation naval surveillance radars domestically.
Strategic Significance
