Extended Range Anti-Submarine Rocket (ER-ASR)

• The Defence Research and Development Organisation's (DRDO) Pune-based facilities created the Extended Range Anti Submarine Rocket (ER-ASR), which was successfully test-fired for the first time from the Navy's INS Chennai.
  • According to DRDO officials, the rocket is intended to replace the current Russian-made Rocket Guided Bombs (RGBs).
• The ER-ASR was created with the intention of detecting submarines at certain depths.

Key Features

• The rocket system will be used in anti-submarine operations and will be launched from an indigenous rocket launcher installed onboard several Indian naval ships.
• It is made up of two motor propulsion systems that can launch the rocket in Short Range and Long Range modes to achieve various range capabilities.
• Depending on the tactical mission requirements, ER-ASR can be launched in a single or salvo mode.

Performance

• The performance of the rocket system was assessed during the initial tests from the Navy's guided missile destroyer INS Chennai at a short range of 2.7 kilometres and in long-range mode at 8.5 kilometres.
• The underwater explosion impact of the missile was observed by the onboard sonar equipment.

Significance

• Steps towards Atma Birbhar Bharta: The first successful test from the ship, according to DRDO officials, is a step towards improving the Indian Navy's capacity for anti-submarine warfare and towards reaching "Atma Nirbharta" in defence.
• Import Substitution: According to DRDO officials, the ER-ASR was created to replace the ship-mounted RGB rockets of existing Russian provenance. The ER-ASR can attain a range of nearly eight kilometres, whilst the RGB has a range of only five kilometres.
