Market Overview & Growth Potential
Current Landscape
India's radar and sonar systems market sits at an inflection point, driven by a dual growth engine: government-led defence modernisation and expanding civilian applications in meteorology, aviation, and coastal security. According to Expert Market Research (2025 data), the India radar market reached approximately USD 1.22 billion in 2025 and is projected to grow at a CAGR of 4.30% through 2035 to reach USD 1.86 billion. In the broader surveillance radar segment, the trajectory is even steeper—Mobility Foresights (2025 data) projects the India surveillance radar market growing from USD 4.8 billion to USD 8.2 billion by 2032, a CAGR of 8.0%.
The sonar systems segment mirrors this trend, with the global sonar market projected to grow from USD 4.58 billion in 2025 to USD 6.15 billion by 2030, according to a ResearchAndMarkets report (2026 data). India is emerging as a significant driver of this growth, with the Defence Research and Development Organisation (DRDO) investing heavily in indigenous sonar capabilities for the Indian Navy.
