The real range of AGNI 5 is 8000 KM as attested by the chinese and Bharat Karnad

Agni-5 IRBM is expected to be fired a second time tomorrow from Wheeler on a depressed trajectory into the Indian Ocean. There are some important issues to consider about this missile. While itll eventually be an all-composite (kevlar) system, the unit to be launched Sunday, Sept 15, retains an all-steel first stage including rocket motor, with the second stage, casing, motor and all being composite. While head of DRDO, Avinash Chander, has talked of canisterizing Agnis, including Agni-5, this second launch will be a straight-up launch to collect more data on various aspects of the missile system in flight and to be reassured that the very successful first launch in April-2012 was not a fluke! Moreover, while ASL, Hyderabad, has a lots of experience with the 1 metre dia missile system (on Agni-2 & 3), A-5 is 2 metre dia missile configured to reach 8,000 kms and carry 3-7 MIRVed warheads to extend its reach to ICBM range. Thumbs up for A-5!
The problem is we have only nuclear bums tested and they weigh like a donkeys payload.
simulated thermonuclear warheads fool no one.So with this donkey payload the range is 5500km only.
