India to test missile defence shield once again in August

It's a no-brainer that with two long, unresolved borders with nuclear-armed China and Pakistan, India needs to develop an effective missile defence shield as soon as possible. The good news is that India is planning another test of its fledgling ballistic missile defence (BMD) system next month.
BMD systems, however, are incredibly complex. They have to detect, classify, track and then hit a fast-incoming hostile missile with interceptors or anti-missile missiles with virtual pinpoint accuracy, all within a matter of minutes. No one, after all, wants nukes to leak through the so-called shield. And if there are multiple enemy missiles, it becomes all the more formidable.
Even the BMD systems of US, Russia and Israel are yet to be proven in actual conflict. The US, of course, has spent billions of dollars on its missile defence systems like Patriot Advanced Capability-3, Aegis BMD-3 and THAAD (terminal high-altitude area defence) system, the last of which was tested as recently as Tuesday.
But DRDO remains upbeat about its seemingly unrealistic claim that Phase-I of its two-tier BMD system, designed to track and destroy hostile missiles both inside (endo) and outside (exo) the earth's atmosphere, will be "ready for deployment'' as early as 2012.
Phase-I is designed to intercept enemy missiles with a 2,000-km range, while Phase-II is meant to tackle 5,000-km range missiles, as reported by TOI earlier. While Phase-I interceptors fly at 4.5 Mach high-supersonic speeds, Phase-II ones will have hypersonic speeds of 6-7 Mach.
"The next test is going to be conducted in August during which we will try to intercept a missile at an altitude of 15-20 km,'' DRDO chief V K Saraswat told reporters here on Thursday.
This will be the fifth test of the Phase-I BMD system. The first three tests, in November 2006, December 2007 and March 2009, when the enemy missiles were `killed' at altitudes of 48-km, 15-km and 80-km respectively, were successful. But the fourth, on March 15 this year, had flopped.
"The anti-missile system is a two-tiered one, where you first launch the target (enemy) missile and then you launch the hit missile. Since the target was not launched as planned (on March 15), the anti-missile system did not trigger,'' explained Saraswat.
This may well be true but DRDO has a long way to go before it can boast of successfully deploying an effective missile shield, with overlapping networks of advanced early-warning and tracking radars, fail-safe command and control posts, and robust land and sea-based interceptor missile batteries.
DRDO is yet to test Phase-I in an integrated mode, with both the two-stage exo and single-stage endo interceptors together, to first engage outside the atmosphere and then intercept the `leakers' inside to ensure the required near 100% kill probability.
Capable of handling multiple targets, the BMD system will have to be repeatedly tested for a variety of flight envelopes before it go in for production and subsequent deployment.

LCA's Naval version prepares to roll out

India's first indigenous Naval Light Combat Aircraft, the LCA (Navy) NP1 is scheduled to roll out from the Hindustan Aeronautics Limited (HAL) Aircraft Research and Design Centre (ARDC) design hangar on July 6.The Defence Ministry has said that the aircraft will be an important milestone for the prestigious Naval Program of Aeronautical Development Agency (ADA), Bangalore.The Chief of The Naval Staff Admiral Nirmal Verma would be the Chief Guest at the function.'Roll-Out' is a significant milestone when the aircraft is brought out of the build hangar, where the aircraft is actually assembled part by part, ready for the phase of systems integration tests leading to Ground runs, taxi trials and flight.Once the ground based tests are completed, the NP1 is expected to fly by the end of this year and the NP2 is likely to fly by the end of 2011.The aircraft, with state of the art technologies and punch, is designed to operate from the future Indigenous aircraft carriers the Navy…

Intercontinental ballistic missiles well within reach

Advanced Systems Laboratory (ASL) is the deceptively bland name that obscures from public view the Defence Research & Development  Organisation’s (DRDO’s) most glamorous laboratory. At the DRDO missile complex here in Hyderabad, ASL develops the ballistic missiles that, in the ultimate nuclear nightmare, will carry Indian nuclear weapons to targets — thousands of kilometres away. Foreign collaboration is seeping into many areas of R&D, but ASL’s technological domain — the realm of strategic ballistic missiles — is something that no country parts with, for love or for money. No foreigner would ever set foot in ASL.
But Business Standard has been allowed an exclusive visit. The erudite, soft-spoken director of ASL, Dr V G Sekharan, describes the technologies that were developed for the DRDO’s new, 5,000-kilometre range Agni-5 missile, which was tested flawlessly in April. He reveals nothing except restraint stood between India and an intercontinental ballistic missile (ICBM) that…

GSLV Mark III with crew module launched successfully

India successfully launched its biggest ever rocket on Thursday, including an unmanned capsule which could one day send astronauts into space, the latest accomplishment of its ramped-up space programme.
The rocket, designed to carry heavier communication and other satellites into higher orbit, blasted off from Sriharikota in Andhra Pradesh.
On Twitter, Prime Minister Narendra Modi hailed the test mission as "yet another triumph of (the) brilliance and hard work of our scientists."
"This was a very significant day in the history of (the) Indian space programme," Indian Space Research Organisation (ISRO) chairman KS Radhakrishnan said from mission control as fellow scientists clapped and cheered.
ISRO scientists have been riding high since an Indian spacecraft successfully reached Mars in September on a shoe-string budget, winning Asia's race to the Red Planet and sparking an outpouring of national pride.
Although India has successfully launched lighter satellit…
