FACTS FOR PRELIMS

Ballistic Missile Defence System

  1. The Indian Ballistic Missile Defence Programme is an initiative to develop and deploy a multi-layered ballistic missile defence system to protect from ballistic missile attacks.
  2. Introduced in light of the ballistic missile threat from mainly Pakistan, it is a double-tiered system consisting of two land and sea-based interceptor missiles, namely- a) The Prithvi Air Defence (PAD) missile for high altitude interception b) The Advanced Air Defence (AAD) Missile for lower altitude interception.
  3. The two-tiered shield should be able to intercept any incoming missile launched from 5,000 kilometres away. The system also includes an overlapping network of early warning and tracking radars, as well as command and control post.

 

Prithvi Air Defence (PAD) or Pradyumna Ballistic Missile Interceptor

i)It is an anti-ballistic missile developed to intercept incoming ballistic missiles outside the atmosphere (exo-atmospheric). Based on the Prithvi missile, PAD is a two-stage missile with a maximum interception altitude of 80 km.

ii)The first stage is a Solid fuelled motor while the second stage is Liquid fuelled.

 

Advanced Air Defence (AAD) or Ashwin Ballistic Missile Interceptor

i)It is an anti-ballistic missile designed to intercept incoming ballistic missiles in the endo-atmosphere at an altitude of 30 km (19 mi).

ii) AAD is a single-stage, solid-fuelled missile.
