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.

Introduced in light of the ballistic missile threat from mainly Pakistan, it is a double-tiered system consisting of two interceptor missiles, namely the Prithvi Air Defence (PAD) missile for high altitude interception, and the Advanced Air Defence (AAD) Missile for lower altitude interception.

The two-tiered shield should be able to intercept any incoming missile launched 5,000 kilometres away
