INS Vikramaditya - some amazing facts to be known

INS Vikramaditya - Brave as the Sun
Type: Aircraft Carrier to serve India for 40 years
Origin: Russia, commissioned in 1987
Original Name: Admiral Gorshkov
Capacity: 45,000-tonne aircraft carrier.
  • The carrier was purchased by India on January 20, 2004 after years of negotiations at a final price of $ 2.35 Billion in 2010.
  • The 284 metre-long and 60-metre-high INS Vikramaditya has a displacement of 45,000 tons, and an endurance of 13,500 nautical miles (25,000 km) at a cruising speed of 18 knots.
  • When delivered, the INS Vikramaditya will be a 90-per cent new ship and will remain in service for 40 years.
  • The futuristic missile defence system that was supposed to be fitted on the Vikramaditya, called the Long Range Surface to Air Missile (LR-SAM).
  • A fleet of MiG-29K naval fighters designated for INS Vikramaditya have already arrived. The on-board arrester wire of the carrier has been designed to support the MiGs and indigenous naval version of the Light Combat Aircraft.
What is LR-SAM Technology being jointly developed by India and Israel?

LR-SAM is a missile, fired from a warship to shoot down an incoming anti-ship missiles at ranges out to 70 kilometres. Israel Aerospace Industries (IAI), Israel is developing the LR-SAM in partnership with the Defence R&D Organisation (DRDO), India.
The LR-SAM is made especially deadly by its two-pulse rocket motor. The first pulse propels the missile towards the incoming target; while a ship-borne radar tracks the enemy missile continuously, transmitting course corrections to the LR-SAM. When the LR-SAM is near the target, its seeker locks onto the target, taking on the job of guidance. Simultaneously, the rocket motor fires its second pulse, imparting to the LR-SAM a high velocity that leaves the target with little time to manoeuvre. The LR-SAM has both front and rear steering, which allows it to manoeuvre sharply, remaining locked onto even a twisting and turning target.
A ground-based version of the LR-SAM is simultaneously being developed for the Indian Air Force (IAF), which is desperately short of air defence systems.
To Add:
  • Russia is the only country with which India has a long-term programme of military-technical cooperation till 2020.
  • Fifth Generation Fighter Aircraft (FGFA), is also being jointly designed and developed by India and Russia.
