More hi-tech than Agni, Astra to take flight this year

After being in the doldrums for quite some time, India's first beyond visual range (BVR) air-to-air missile Astra is now finally set to take flight. Defence scientists, in fact, hope to integrate the missile with a fighter jet for full-scale tests later this year.

In terms of sheer technology, the 80-km-range Astra is more complex than even the nuclear-capable Agni series of strategic ballistic missiles. And that is primarily the reason it has remained largely restricted to the drawing board stage till now.

But now, in the wake of closure of the Integrated Guided Missile Development Programme (IGMDP) in December 2007, after a quarter of a century of hits and misses, defence scientists are basically focusing on Astra and four other missile systems.

The other four are the 700-km range K-15 submarine-launched ballistic missile, the 290-km BrahMos supersonic and hypersonic cruise missiles, the 3,500-km range Agni-III ballistic missile and the long-range surface-to-air missile system being jointly developed with Israel.

"Astra is a very complex missile. We have completed the tests of its navigation, control, airframe, propulsion and other sub-systems. Now, we want to integrate it with a mother aircraft for flight trials," DRDO chief controller Prahlada said. "We have identified three fighters - MiG-29, Jaguar and Tejas Light Combat Aircraft - for integration. But we will have to test it 20 to 50 times, covering the entire flight envelope, before it can become operational," he added.

India requires BVR missiles, fired by fighters to destroy enemy aircraft at ranges beyond 40 km, since the days of dog fights are virtually over now. Being extremely complex, only a few countries like US, Russia, France and Israel have managed to develop BVR missiles till now.

The Indian Sukhoi-30MKIs and Mirage-2000s, for instance, are armed with expensive BVR missiles of French and Russian origin like the "Matra Super 530D" and "AA-12 Adder". India, incidentally, is also importing the Israeli Python and Derby air-to-air missiles.

It was in March 2004 that the government approved the Rs 1,000-crore project to develop Astra, with a 80-km "head-on range", after DRDO conducted test-firing of three prototypes from the Chandipur-on-Sea test range in May 2003. But DRDO will not be able to meet the 2009 deadline for delivery of the Astra missile to IAF. It will only be possible by 2012 or so.

But once operational, scientists hold the single-stage solid-fuelled Astra will be cheaper and advanced than contemporary BVR missiles, capable of engaging and destroying highly-manoeuvreble supersonic aerial targets.

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…
