  1. BrahMos

The issue in news

BRAHMOS, the supersonic cruise missile was successfully test fired from Indian Navy’s indigenously-built stealth destroyer INS Chennai, hitting a target in the Arabian Sea.


Main points

  • BRAHMOS as a prime strike weapon will ensure the warship’s invincibility by engaging naval surface targets at long ranges, thus making the destroyer another lethal platform of Indian Navy.
  • BrahMos Aerospace, an India-Russia joint venture, produces the supersonic cruise missile that can be launched from submarines, ships, aircraft, or from land platforms.
  • In the last few weeks, India has test fired a number of missiles including a new version of the surface-to-surface supersonic cruise missile BrahMos and anti-radiation missile Rudram-1.
  • The original 290-km range BrahMos has already been deployed in Ladakh as well as Arunachal Pradesh during the ongoing military confrontation with China.
  • The armed forces have already inducted the 290-km range land and warship-based versions of the BrahMos missiles, which fly almost three times the speed of sound at Mach 2.8, over the last decade



The issue in news

The indigenously developed laser-guided version of the Anti-Tank Guided Missile (ATGM) was successfully test fired by the Defence Research and Development Organisation (DRDO) on two separate occasions recently.


Main points

  • ATGMs are missile systems that can strike and neutralise armoured vehicles such as tanks.
  • While Indian Army mainly uses various imported anti-tank guided missiles, the DRDO has been working on ATGMs that can be launched from different platforms as part of the Integrated Guided Missile Development Programme.
  • The indigenously developed low weight, fire and forget Man Portable Anti-Tank Guided Missile (MPATGM) was successfully in September last year.
  • In February 2018, ATGM Nag was successfully tested in desert conditions. All these systems, which are mainly used by infantry units of the Army, are in their various stages of development.
  • In the meantime, the government said in December 2019 that it has procured Anti-Tank Spike Missiles from Israel along with the allied systems to meet operational requirements of the Indian Army.

Important Info:

How are laser-guided ATGMs different?

  • The laser-guided ATGM, which was successfully tested recently on September 22 and later on October 1, mainly differs in one aspect from other ATGMS developed till date.
  • This ATGM — which is yet to receive an operational name — is designed to be fired from tanks. With its range limited to 1.5 to 5 kilometers, it locks and tracks the targets with the help of laser designation to ensure precision in striking the target.
  • The missile uses a ‘tandem’ High Explosive Anti-Tank (HEAT) warhead. The term tandem refers to the missiles using more than one detonation in order to effectively penetrate the protective armours
