India’s TASL and Spain’s Indra Commission 3D-ASR Lanza-N: A Naval Technology Milestone on INS Mysore

In a major boost to India’s naval capabilities, the Indian Navy has successfully commissioned the first 3D Air Surveillance Radar (3D-ASR) – Lanza-N on the warship INS Mysore. This cutting-edge radar system is a collaborative development between India’s Tata Advanced Systems Limited (TASL) and the Spanish defence technology giant Indra. The commissioning, completed in 2025 after rigorous sea trials, marks a significant milestone in maritime defence technology and India’s push for indigenisation and strategic partnerships.

The Lanza-N Radar: A Technological Marvel

The Lanza-N radar is a naval variant of Indra’s highly advanced Lanza 3D radar. It provides long-range, three-dimensional tactical surveillance capabilities that are crucial for detecting and tracking both friendly and hostile air and surface targets. Designed to function reliably in the high humidity and extreme heat conditions of the Indian Ocean Region, the radar enhances the Indian Navy’s ability to detect a wide array of aerial threats, including drones, supersonic fighters, and anti-radiation missiles. It completes a full rotation every 10 seconds, offering real-time, continuous situational awareness.

Strategic Significance and Operational Integration

The radar system boasts seamless integration with all shipboard systems on INS Mysore, ensuring optimal operational efficiency. The successful integration and commissioning followed extensive sea trials, involving diverse naval and aerial platforms to assess its performance across a spectrum of radar cross-sections.

The project underlines India’s growing self-reliance in defence technology through collaboration with international leaders. TASL has also set up a radar assembly, integration, and testing facility in Karnataka, which will expedite the production and deployment of subsequent radar units across the Indian Navy’s fleet — including frigates, destroyers, and aircraft carriers.

India-Spain Defence Collaboration

This partnership with Spain’s Indra exemplifies a model of international defence collaboration combined with local manufacturing expertise. As Ana Buendía, Head of Indra’s Naval Business Unit, emphasized, the project transcends mere product delivery, establishing a long-term radar manufacturing and support ecosystem in India. This collaboration ensures not only advanced technology transfer but also strategic autonomy and economic benefits.

Future Prospects

The commissioning of the Lanza-N radar aboard INS Mysore is the beginning of a broader rollout expected over the next decade. With the local assembly and integration facility operational, the Indian Navy is well-positioned to maintain cutting-edge situational awareness capabilities vital for safeguarding maritime interests and enhancing regional security.
