9 PAD/ AAD BALLISTIC MISSILE DEFENSE (BMD) SYSTEM
The Indian BMD program raised eyebrows when it was first announced and has come a long way since. It has been successfully tested against a short range ballistic missile and is reportedly deployable at short notice to protect major cities. Two interceptor missiles, the PAD (Prithvi Air Defence)and the AAD (Advanced Air Defence) along with the Green Pine radar form the core of this system. The PAD is an exo-atmospheric interceptor with a ceiling of over 80 km and a range of over 2000 km. It is used to intercept ballistic missiles which are travelling outside the Earth’s atmosphere. The AAD is an endo-atmospheric interceptor with a range of 250+ km and a ceiling of 30 km. It’s used to intercept short range ballistic missiles. Both these missiles initially guided by an Inertial Navigation System (INS) and have an active radar seeker for homing in on the target.
