Recently, on 29th July 2012, a developmental flight test was carried out from Integrated Test Range (ITR), Chandipur with 25 new components and subsystems produced in India substituting those made from Russia. In this test, except for one subsystem, all other subsystems and components have performed to the requirement.
Malfunction of one subsystem resulted in increase in velocity of the missile, crossing the limit and leading to aborting the mission. The defect has been rectified after analysis. Further development flight tests will be conducted as a measure of self-reliance.
This information was given by Defence Minister Shri AK Antony in a written reply to Shri Anil Desai in Rajya Sabha today.
