India Unveils First Indigenous 3D Naval Radar with Global Collaboration

In a major boost to India’s naval modernisation, Tata Advanced Systems Limited (TASL) and Spanish defence company Indra have successfully delivered the country’s first indigenously produced 3D naval air surveillance radar. The system, named Lanza-N, has now been deployed on an Indian Navy warship, signalling a new era of homegrown maritime technology.

The radar has been designed to track multiple aerial and surface threats simultaneously, including advanced aircraft, drones, missiles, and stealth platforms. According to defence officials, the system underwent extensive sea trials before being cleared for full operational use.

Strengthening Aatmanirbhar Bharat in Defence

The radar is being assembled and tested at a newly established facility in Karnataka, ensuring that future units will be largely produced in India. This not only enhances the Navy’s combat readiness but also cuts down reliance on overseas suppliers for critical sensor technology.

A senior official from TASL noted that the programme represents more than technology transfer: “It’s about building long-term capability within India’s defence ecosystem, from design and integration to maintenance and upgrades.”

Why the Lanza-N Radar Matters

• Operational Superiority: The radar can detect and classify threats at long ranges, giving naval commanders crucial decision-making time.
• Strategic Security: Its deployment strengthens maritime domain awareness across the Indian Ocean Region, where evolving threats demand faster and smarter responses.
• Industrial Growth: The Karnataka facility will generate new skilled jobs and nurture a local supply chain for advanced electronics and defence components.
• First Outside Spain: India becomes the first nation beyond Spain to operationalise the Lanza-N system, reflecting strong trust and collaboration with Indra.

The Road Ahead

The Indian Navy is expected to commission additional radars in coming years as part of a broader upgrade to its sensor network. With TASL and Indra pushing for deeper localisation, India is on track to transform its maritime surveillance infrastructure and emerge as a global player in naval technology development.
