The PAD missile has the secondary stage of the Prithvi missile and can reach altitude of . During the test, the target missile was intercepted at a altitude.Prithvi Mission Milestone in Missile Defence . On 6 December 2007, the Advanced Air Defence (AAD) missile system was tested successfully. This missile is an endo-atmospheric interceptor with an altitude of . First reported in 2009, the Defence Research and Development Organisation (DRDO) is developing a new Prithvi interceptor missile code-named PDV. The PDV is designed to take out the target missile at altitudes above . The first PDV was successfully test fired on 27 April 2014. On 15 May 2016, India successfully launched AAD renamed Ashwin from Abdul Kalam Island off the coast of Odisha. As of 8 January 2020, the BMD programme has been completed and the Indian Air Force and the DRDO are awaiting government's final approval before the system is deployed to protect New Delhi and then Mumbai. After these two cities, it will be deployed in other major cities and regions. PAD and PDV are designed for mid-course interception, while AAD is for terminal phase interception. India had previously planned to acquire NASAMS-II but the Indian Air Force instead is now seeking a domestic alternative (potentially the land-based VL-SRSAM).
