In a significant achievement for India’s indigenous defence capabilities, user trials of the Extended Range Anti-Submarine Rocket (ERASR) were successfully conducted from Indian Naval Ship (INS) Kavaratti between June 23 and July 7, 2025. Developed by the Armament Research & Development Establishment (ARDE), Pune, a DRDO lab, in collaboration with High Energy Materials Research Laboratory (HEMRL) and Naval Science & Technological Laboratory (NSTL), the ERASR system is poised to strengthen the Indian Navy’s underwater warfare arsenal.
Indigenous Innovation for Naval Dominance
The ERASR is a fully indigenous anti-submarine rocket designed for deployment from the Indigenous Rocket Launcher (IRL) systems fitted on Indian Naval ships. It has a twin-rocket motor configuration, enabling it to engage submarine targets at various ranges with exceptional accuracy and consistency.
A key highlight of the ERASR is its indigenously developed Electronic Time Fuze, which enhances its precision and reliability. The system has been rigorously tested for range performance, fuze activation, and warhead functionality.
Trial Results and Operational Readiness
During the extensive trials, 17 ERASR rockets were launched and successfully evaluated at multiple range configurations. All critical performance parameters, including timing, accuracy, and detonation reliability, were met or exceeded. With these successful trials, the Indian Navy is now expected to induct the ERASR system into active service, significantly boosting its anti-submarine warfare (ASW) capabilities.
Public–Private Partnership in Defence Manufacturing
The production of ERASR rockets will be undertaken by:
-
Bharat Dynamics Limited (BDL), Hyderabad
-
Solar Defence & Aerospace Limited, Nagpur
These partnerships reflect the growing strength of India’s defence industrial base and the increasing role of private industry in delivering cutting-edge strategic weapon systems.
Leaders Laud the Milestone
Raksha Mantri Shri Rajnath Singh congratulated DRDO, Indian Navy, and industry partners for the successful development and testing of ERASR. He noted that its induction would “significantly enhance the Indian Navy’s striking power and operational flexibility in ASW operations.”
Dr. Samir V. Kamat, Secretary, Department of Defence R&D and Chairman, DRDO, also praised the scientific teams behind the innovation, underlining its role in achieving self-reliance in defence technology.
The ERASR system not only reinforces India’s resolve to equip its naval forces with state-of-the-art, home-grown weapons, but also marks a crucial step in transforming the Indian Navy into a future-ready blue water force.
