Details about present test
The Defence Research and Development Organisation (DRDO) successfully carried out a test of an interceptor missile, further validating the reliability of the under-development, two-layered Ballistic Missile Defence (BMD) in shooting down enemy missiles.

Defence sources said the endo-atmospheric missile, which can intercept missiles at ranges of 15-30 km, was launched. from the Abdul Kalam Island off the Odisha coast in response to an incoming missile which was launched from the Integrated Test Range (ITR) in Chandipur. The missile intercepted the incoming missile at an altitude of 15 km. 

Details of earlier test
Last month, the DRDO carried out a successful test of the exo-atmospheric interceptor missile destroying the target outside the earth’s atmosphere at an altitude of over 85 km.

Indian Ballistic Missile Defence Programme  
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 land and sea-based interceptor missiles, namely the Prithvi Air Defence (PAD) missile for high altitude interception (for exo-atmospheric range), and the Advanced Air Defence (AAD) Missile for lower altitude interception (for endo-atmospheric range). The two-tiered shield should be able to intercept any incoming missile launched 5,000 kilometres away. The system also includes an overlapping network of early warning and tracking radars, as well as command and control posts. 

The PAD was tested in November 2006, followed by the AAD in December 2007. With the test of the PAD missile, India became the fourth country to have successfully developed an anti-ballistic missile system, after United States, Russia, and Israel. The system has undergone several tests but system is yet to be officially commissioned.DRDO expects to have shield ready for deployment by 2022.
