Hey guys India is also pursuing its Ballistic Missile Defense programme, it has conducted succesfully an Exo-atmospheric interceptor test and is ready to conduct an Endo-atmospheric test in December this year.

NEW DELHI: In the first week of December, the country plans to unleash a new "interceptor" missile to "kill" an incoming "hostile" missile over the Bay of Bengal.
During the test, a Prithvi missile, modified to "mimic" a hostile ballistic missile with a 300-1,000 km range, will first be fired from the Balasore interim test range in Orissa.
The incoming missile will then be tracked by long-range tracking radars (LRTRs), developed with Israeli help and is a part of the automated command and control network. LRTRs in turn will convey the "threat" to the "endo" (taking the "enemy" missile at an 15-20 km altitude above the earth) missile battery in far away Wheeler Island.
Finally, the interceptor missile will blast off with a roar to eventually destroy the "enemy" missile in fireworks over the Bay of Bengal. The new "endo" missile has been dubbed AAD (advanced air defence), while the "exo" missile was called PAD (Prithvi air defence).
"The endgame this time will be technologically more complex than the exo test because of atmospheric disturbances and other factors. AAD, in fact, will be slightly better than PAC-3 in terms of range and altitude of interception," said DRDO chief controller, R&D, V K Saraswat. In the next phase, defence scientists plan to test PAD and AAD together in an integrated mode. But before you think that India now finally has some sort of a missile defence shield to guard against Pakistani and Chinese nuclear-capable missiles, hold your breath. Such a capability is still several years away.
For one, BMD capabilities are very complex. For another, they require huge investments. Given its size, India would require a large overlapping network of early-warning sensors, command posts and anti-missile land and sea-based missile batteries.
A missile launched from Pakistan, after all, can reach India in barely 5 to 7 minutes. But yes, it can be said India is now finally on its way to join the US, Russia and Israel in the very exclusive BMD club.
"The system will have to be tested for a variety of flight envelopes. We will have to undertake 5-6 trials over the next 2-3 years to validate the complete spectrum of engagement. Only after that can the production and operationalization phase commence," said Saraswat. The 10-metre tall PAD missile was designed by taking Prithvi's propulsion system and adding a second stage to it to ensure it goes up to a height of about 80 km.
The 7-metre tall AAD interceptor, in turn, is a new single-stage missile, powered by solid propellant, with terminal homing seekers and inertial navigation system. It will be able to reach an altitude of almost 30 km.
Interestingly, the crucial LRTRs used in the tests are based on the two Israeli Green Pine early-warning and fire control radars imported by India in 2001-2002.
"But we have upgraded LRTR, which is 30-40% better in target classification and identification. It can prioritize the incoming threats and track 200 targets simultaneously," said Saraswat.
LRTR has a detection range of 600 km and is capable of tracking intermediate range ballistic missiles, with velocities up to 5,000 metre per second. Incidentally, a ballistic missile can be targeted at all the three points in its parabolic trajectory — boost or launch phase, mid-course in space or terminal phase during atmospheric descent.
DRDO, on its part, has designed the BMD system, which will be upgraded in the coming years, to intercept an incoming missile at both the "second mid-course and terminal phases".
