The Indian Navy has conducted user trials of the extended range anti-submarine rocket (ERASR) from anti-submarine warfare corvette INS Kavaratti.

As disclosed, the trials were carried out from June 23, 2025, to July 07, 2025. DRDO’s Armament Research & Development Establishment (ARDE), Pune, in association with High Energy Materials Research Laboratory and Naval Science & Technological Laboratory, has designed and developed ERASR for the indigenous rocket launcher (IRL) of Indian naval ships.

ERASR is used to combat submarines and is fired from onboard IRL. It has a twin-rocket motor configuration to meet a wide spectrum of range requirements with high accuracy and consistency. The ERASR uses an indigenously developed electronic time fuze.

A total of 17 ERASRs were successfully tested and evaluated at different ranges, according to the Indian Navy. All the specified objectives of the trials, such as range performance, electronic time fuze functioning and warhead functioning, were successfully demonstrated.

Bharat Dynamics , Hyderabad and Solar Defence & Aerospace, Nagpur, are the production partners for ERASR rockets.

With the successful completion of user trials, the Indian Navy is expected to induct the ERASR system soon.

INS Kavaratti is an indigenously built anti-submarine warfare (ASW) stealth corvette under Project 28 (Kamorta class). It was commissioned into the navy in 2020.

These vessels have 109 metres and 2,500 tons, built by Indian Garden Reach Shipbuilding and Engineering (GRSE) in Kolkata. They are armed with a range of indigenously developed weapons and sensors, including “a medium-range gun, torpedo tube launchers, rocket launchers and a close-in weapon system”. They can also carry an anti-submarine warfare helicopter, which provides forward presence.
