Varunastra is an indigenous heavyweight anti-submarine torpedo designed to be launched from ships.

It was developed by the Naval Science and Technological Laboratory.

According to the Ministry of Defence, the weapon possesses advanced manoeuvring capabilities and can engage enemy submarines at long ranges.

12. What Is a Torpedo?

A torpedo is an underwater weapon designed to travel through water towards a target.

Torpedoes are used in naval warfare, particularly against submarines and, depending on the weapon, surface vessels.

They are distinct from missiles that normally travel through the air for most of their flight.

13. What Is a Heavyweight Torpedo?

Heavyweight torpedoes are a category of relatively large underwater weapons used for naval combat missions.

They are designed for demanding operational requirements, including engagements against submarines.

Varunastra is specifically identified in the official announcement as a ship-launched heavyweight anti-submarine torpedo.

14. Ship-Launched Versus Submarine-Launched Weapons

A ship-launched torpedo is deployed from a surface warship, while a submarine-launched torpedo is deployed from a submarine.

The October 2026 contract identifies Varunastra as a ship-launched system.

Students should not change the platform designation when answering examination questions about this specific announcement.

15. What Is Anti-Submarine Warfare?

Anti-Submarine Warfare, abbreviated ASW, refers to operations intended to detect, track, deter or engage hostile submarines.

It may involve surface warships, aircraft, helicopters, underwater sensors and specialised weapons.

Submarines can be difficult to locate because they operate underwater and may use techniques intended to reduce detection.

16. Importance of Varunastra for the Indian Navy

Varunastra is intended to strengthen the Indian Navy's capability to engage hostile submarines.

The Ministry of Defence highlighted the weapon's manoeuvrability and long-range engagement capability.

Such weapons form part of a wider anti-submarine warfare system that also requires detection, tracking, targeting and operational coordination.
