Centre gives new life to Agni-III
Rahul Datta | New Delhi
The Government has given the go-ahead to the Defence Research and Development Organisation (DRDO) scientists
to conduct at least two tests of the Agni-III intermediate range ballistic missile in late August.
The nod for the two tests,
likely to be conducted in quick succession at a gap of two or three days, came on Wednesday when the DRDO brass met Defence Minister Pranab Mukherjee.
The Minister was also apprised of the plausible cause of the snag which afflicted the maiden test firing of the missile on Sunday last, sources said here on Thursday.
The scientists said they were ready for further tests of the missile capable of hitting a target at a distance of 3,500 kms and with the capacity to carry conventional and nuclear warheads up to one tonne. .....

The DRDO also briefed the Minister about the plausible cause of the snag and
assured him that they would be able to rectify the snags for the forthcoming launches. The tests would be two-stage even as the DRDO was ready with a three-stage missile test, sources said.
The cause of the snag as reported to the Minister was that the Sunday test was carried for the two-stage missile with a booster but without changing the composition of the propellant.
It means that the propellant used for this test was similar to that used for Agni-II which has a range of hitting a target at 2,000 kms.
However, if the objective is to hit a target beyond 2,000 kms, the chemical specifications of the solid fuel propellant have to be changed to give additional thrust to the missile, they said.
Explaining further, they said the Agni-III, most probably, developed a snag as the booster of the missile, used to ignite the missile was not compatible with the second stage of hitting the target. This phenomenon occurred due to design failure as the diameter of the missile was increased to store more propellant without changing its composition technically known as specific impulse composition, sources said.
