The Anti-Torpedo Torpedo (ATT) is a "hard-kill" countermeasure system
designed to intercept and destroy incoming enemy torpedoes before they reach
their target. While the Defence Research and Development Organisation (DRDO)
has successfully inducted "soft-kill" systems like Maareech, it is also
actively researching and developing ATT technologies to provide a more
definitive defence for the Indian Navy's frontline warships and submarines.
DRDO continues to bolster India's naval defences through cutting-edge
anti-torpedo technologies, addressing the persistent underwater threats posed
by adversarial submarines. Central to these efforts are the Maareech Advanced
Torpedo Defence System (ATDS) and the Supersonic Missile-Assisted Release of
Torpedo (SMART) system, both designed to safeguard frontline warships and
extend anti-submarine warfare (ASW) capabilities.
Maareech represents a fully indigenous solution developed by DRDO's Naval
Science and Technological Laboratory (NSTL) and Naval Platforms (NP) groups.
This ship-launched system excels in detecting, locating, and neutralising
incoming torpedoes through a sophisticated array of sensors and decoy
mechanisms. By deploying acoustic decoys, it confuses and diverts enemy
torpedoes away from vessels, providing a critical layer of protection in
high-threat maritime environments.
Induction of Maareech into the Indian Navy marks a significant milestone, with
deployments now underway across all major frontline warships. Successful
trials have validated its reliability, integrating seamlessly with existing
naval combat systems. This advancement reduces reliance on foreign imports,
aligning with India's Atmanirbhar Bharat initiative in defence manufacturing.
Complementing Maareech is the SMART system, a revolutionary canister-launched
supersonic missile that dramatically extends the reach of lightweight
torpedoes. Unlike conventional torpedoes limited to 20-40 kilometres, SMART
propels its payload over hundreds of kilometres, enabling strikes against
submerged threats from stand-off distances. This capability transforms naval
tactics, allowing ships to engage enemy submarines without entering their
torpedo envelope.
The SMART system's architecture includes a booster rocket for supersonic
flight, followed by a parachute-retarded release of the torpedo at the target
zone. DRDO has conducted multiple successful flight tests, culminating in
precision deployments over the Bay of Bengal. These trials demonstrate the
system's accuracy, with the torpedo achieving terminal guidance via advanced
sonar homing.
Comparison: Soft-Kill Vs Hard-Kill
| Feature | Soft-Kill (e.g., Maareech) | Hard-Kill (ATT) |
|---|---|---|
| Method | Diversion via Jammers/Decoys | Physical Interception |
| Success Rate | Depends on "fooling" the Torpedo | High, as it neutralises the threat |
| DRDO Status | Fully Inducted (June 2020) | Under Research/Development |
Beyond defence, these technologies enhance offensive ASW operations. Paired
with systems like the Varunastra heavyweight torpedo—a DRDO-developed,
wire-guided weapon with a 40-kilometre range and multi-speed capabilities—they
form a comprehensive underwater arsenal. Varunastra, already inducted,
features pump-jet propulsion for stealth and a 90-kilogram warhead optimised
for deep strikes.
DRDO is also advancing the Electric Heavyweight Torpedo (EHWT), a
next-generation swimmer-delivery vehicle for covert submarine operations. This
electrically propelled torpedo promises superior endurance and reduced
acoustic signatures compared to legacy designs, bolstering the Indian Navy's
deep-strike potential against high-value targets.
These developments underscore DRDO's prowess in underwater acoustics, sensor
fusion, and propulsion technologies. Collaborative efforts with public sector
undertakings like Bharat Dynamics Limited (BDL) ensure scalable production,
while integration with platforms such as the INS Vikrant aircraft carrier
amplifies strategic deterrence in the Indian Ocean Region.
Challenges persist, including countering advanced acoustic-homing torpedoes
from adversaries like China and Pakistan. DRDO addresses these through ongoing
R&D in AI-driven threat classification and multi-static sonar networks.
Future iterations may incorporate hypersonic elements or unmanned underwater
vehicles (UUVs) for layered defence.
In essence, Maareech and SMART exemplify India's leap towards self-reliance in
naval warfare, fortifying maritime security amid rising regional tensions. As
testing progresses, these systems will equip the Navy to dominate contested
waters, deterring aggression and projecting power effectively.
