DRDO completes upgrade of MiG-27 for IAF

India has successfully completed the upgrade programmes on the Indian Air Force's (IAF) MiG-27 ground attack fighter aircraft.

The Defence Research and Development Organisation (DRDO) carried out the avionics upgrades on the fighter aircraft.

Initiated in 2002 through a tri-partite Memorandum of Understanding (MoU) between Defence Avionics Research Establishment (DARE), Hindustan Aeronautics Limited (HAL) and IAF, the upgraded MiG-27 aircraft obtained the Initial Operational Clearance in June 2006, which led to the subsequent formation of operational squadrons, DRDO officials said here today.

In the upgraded MiG-27s, the avionics system is built around a modular mission computer termed Core Avionics Computer (CAC).

"These functional modules are powering the mission computers on Jaguar and Su-30 MKI aircraft as well," sources said.

The upgraded ground attack fighters are equipped with Inertial Navigation and Global Positioning System (INGPS) providing accurate navigation during aircraft sorties.

To provide more accuracy to the aircraft's weapon systems, accurate ranging sensors such as Laser Designator Pod (LDP) and Laser Ranger and Marked Target Seeker (LRMTS) have been integrated in it also, they said.

To improve situational awareness of the pilot during air combat, a digital map generator has been integrated along with a digital video recording system, which helps in mission analysis and debrief support.

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…
