India successfully conducted user trials of its indigenous Extended Range Anti‑Submarine Rocket (ERASR) from INS Kavaratti in July 2025. The trials mark a milestone in developing home‑grown anti‑submarine warfare capabilities.
What is ERASR?
- ERASR is a next‑generation underwater weapon designed by the Defence Research and Development Organisation (DRDO) to neutralise enemy submarines and torpedoes.
- The rocket employs a twin‑motor propulsion system, allowing it to operate in two modes: a short‑range motor for nearby threats and a long‑range motor for targets farther away.
- It uses a locally developed electronic time fuze that ensures precise detonation at the desired depth and improves safety.
Features and significance
- Range and precision: Capable of engaging underwater threats at different ranges with high accuracy.
- Indigenous design: All components, including warheads and fuzes, are developed in India, boosting self‑reliance and reducing import dependence.
- User‑friendly launcher: The rocket is compatible with indigenous launchers installed on frontline warships like the Kamorta‑class corvettes.
- Strategic value: Enhances the Indian Navy’s anti‑submarine warfare capability, a key requirement for protecting naval assets in the Indian Ocean Region.
