Local production

India has several local versions of the RGB-60. An indigenous version by HAPP and Tiruchi was reported in 2010.^[2] In 2012 a version of the RGB-60 was provided to the Indian Navy by Ammunition Factory Khadki with a strike range of 1,500 m.^[3] In 2023, a new YDB-60 fuse was delivered.^[4]

Extended Range Anti-Submarine Rocket (ERASR)

This section is an excerpt from Projects of DRDO § Extended Range Anti-Submarine Rocket (ERASR).[edit]

In 2020s, the Extended Range Anti-Submarine Rocket (ERASR) was developed by India's Defence Research and Development Organisation (DRDO) with Armament Research and Development Establishment (ARDE) as the nodal development agency as an extended range variant of existing RGB-60 rocket. Other establishment's under DRDO including High Energy Materials Research Laboratory (HEMRL) and Naval Science & Technological Laboratory (NSTL) were also involved in the project. ERASR has twin motor propulsion system which can fire the rocket in short range and long range mode to achieve a distance of 500–8,900 m (1,600–29,200 ft). The rocket was successfully test fired from INS Chennai (D65) on 3 April 2023.^[5][6]

Between 27 June and 3 July 2025, the Indian Navy completed the user trials of ERASR from the Indigenous Rocket Launchers (IRL) onboard INS Kavaratti (P31). A total of 17 rockets were successfully fired at different ranges during the trials. Each of the objective of the trials, including warhead functioning, electronic time fuze operation, and range performance, were effectively demonstrated. In this development, Bharat Dynamics Limited and Solar Defence & Aerospace Limited are the production partners of the rocket system. The Navy is also expected to induct the ERASR System soon.^[7]
