India's two-layered anti-missile shield is ready for induction, and deployment for defence of the national capital, DRDO chief V.K. Saraswat has said in a television interview to The Indian Express editor-in-chief Shekhar Gupta. The system, which comprises an exo-atmospheric interceptor PAD and endo-atmospheric interceptor AAD (in photo) has often been put on-par with the Patriot PAC-3 by the DRDO leadership.The DRDO began testing its anti-missile system in November 2006 with an unannounced test (I remember being in Egypt at the time, and reading about it online from a cyber cafe in Aswan).
