New Delhi: India is rapidly strengthening its maritime defence with the development of the DRDO Anti-Torpedo Torpedo (ATT) system, a next-generation underwater shield designed to neutralise enemy torpedoes before impact.
The Defence Research and Development Organisation (DRDO) is combining advanced systems like Maareech and SMART to build a multi-layered defence for the Indian Navy. This initiative is crucial as underwater threats from adversarial submarines are increasing in the Indian Ocean region.
What is the DRDO ATT System
The Anti-Torpedo Torpedo (ATT) is a “hard-kill” defence system.

It is designed to detect, track, and destroy incoming torpedoes before they hit ships or submarines.
- It directly intercepts enemy torpedoes mid-water
- Uses advanced sensors and guidance systems
- Provides last-line defence for naval platforms
Unlike traditional systems, ATT does not just confuse the enemy—it physically destroys the threat.
Soft-Kill vs Hard-Kill: Understanding the Difference
DRDO is developing a two-layer defence strategy:
1. Soft-Kill System – Maareech
- Already inducted in the Indian Navy
- Detects incoming torpedoes
- Launches decoys to mislead enemy torpedoes
This system reduces the chances of a direct hit by confusing enemy guidance systems.
2. Hard-Kill System – ATT
- Still under development
- Physically destroys incoming torpedoes
- Acts as a final protective shield
Together, these systems create a highly effective layered defence mechanism.
What is the Role of SMART System in Anti-Submarine Warfare
Another major component is the SMART (Supersonic Missile Assisted Release of Torpedo) system.
- Launches a torpedo using a supersonic missile
- Engages enemy submarines from long distances
- Operates at speeds up to Mach 2.5
- Can strike targets hundreds of kilometres away
SMART significantly enhances India’s anti-submarine warfare (ASW) capability by allowing fast and long-range response.
Why DRDO ATT System is Important for India
The development of ATT comes at a time when underwater threats are increasing globally.
Key Reasons:
- Growing submarine presence in the Indian Ocean
- Need to protect aircraft carriers and warships
- Increasing importance of underwater warfare
- Requirement for indigenous defence technologies
India’s naval platforms, including submarines and surface ships, rely heavily on torpedoes for both attack and defence.
How DRDO is Boosting Indigenous Naval Power
DRDO’s work in underwater weapons is led by specialised labs like the Naval Science and Technological Laboratory (NSTL), which focuses on torpedoes and related systems.
Key Developments:
- Indigenous torpedoes like Varunastra
- Advanced torpedo defence systems
- Integration of missile and torpedo technologies
This aligns with India’s Atmanirbhar Bharat (self-reliant India) mission in defence manufacturing.
What is the Impact of DRDO ATT System on Indian Navy
The ATT shield will significantly enhance the survivability of:
- Aircraft carriers
- Destroyers and frigates
- Nuclear and conventional submarines
It ensures that even if an enemy torpedo is launched, the ship has multiple chances to survive.
Future Outlook
DRDO is actively working to integrate ATT with existing naval systems. Once deployed:
- India will join a select group of nations with advanced torpedo defence
- Naval platforms will have layered protection
- Underwater warfare capabilities will improve significantly
The combination of Maareech + ATT + SMART will create a comprehensive underwater defence ecosystem.
