• This helps in :
  1. Detecting enemy submarines
  2. Understanding underwater terrain for naval operations
  3. Strengthening anti-submarine warfare capabilities

5. Strategic Intelligence During Missile Tests

• INS Dhruv can be deployed near missile test zones (in international waters) to :
  • Observe missile launches of other countries
  • Collect telemetry and radar data
  • Analyse performance of foreign missile systems

This provides India with critical insights into adversaries’ capabilities.

6. Enhancing Space and Satellite Monitoring

• The ship is also capable of tracking satellites and space-based assets, expanding its role beyond maritime operations.
• This contributes to :
  1. Space situational awareness
  2. Monitoring of satellite launches and movements
