First test launch :-
On 19 April 2012 the Agni V was successfully test-fired by DRDO from Wheeler Island off the coast of Odisha.The test launch was made from the Launch Complex 4 of the Integrated Test Range (ITR) at Wheeler Island using a rail mobile launcher. The flight time lasted 20 minutes and the third stage fired the re-entry vehicle into the atmosphere at an altitude of 100 kilometres (62 mi). The missile re-entry vehicle subsequently impacted the pre-designated target point more than 5,000 kilometres (3,100 mi) away in the Indian Ocean. The director of the test range, S.P. Das, informed BBC that all test parameters were met. According to news reports the Agni-V was able to hit the target nearly at pin-point accuracy, within a few metres of the designated target point.
Second test launch:-
On September 15, 2013 India conducted a second test flight of Agni-V from the Wheeler Island off Odisha coast. The missile was test-fired from a mobile launcher from Launch Complex 4 of the Integrated Test Range (ITR). The flight duration was little over 20 minutes and hit the pre-designed target in the Indian Ocean with an accuracy of a few metres.
Third test launch:-
On 31 January 2015, India conducted a third successful test flight of the Agni-V from the Wheeler Island facility. The test used a canisterised version of the missile, mounted over a Tatra truck . The Integrated Test Range Director, M. V. K. V. Prasad, "The missile, witnessed a flawless 'auto launch' and detailed results will be known after all data is retrieved from different radars and network systems."
Fourth test launch:-
On 26 December 2016, a fourth test of the missile was successfully conducted from complex 4 of Wheeler Island, Odisha at 11.05 IST. This was the second canisterised test of the missile and will now pave way for user trials of the missile by the Strategic Forces Command (SFC).
Fifth test launch:-
On 18 January 2018, a fifth test of the missile was successfully conducted from the Wheeler Island facility, Odisha at 09.53 IST. This was the third consecutive canisterised test of the missile on a road mobile launcher and the first in its final operational configuration. The missile covered a distance of 4,900 km in 19 minutes.
Sixth test launch:-
On 3 June 2018, a sixth test launch of Agni-V was successfully conducted from Abdul kalam Island. It was the sixth missile test since 2012 and was a “precision launch”. The Indian Ministry of defence stated that the radars, electro-tracking stations, and telemetry stations tracked the vehicle throughout the course.
MIRVs :-
Agni-V is expected to feature Multiple Independently Targetable reentry Vehicle (MIRVs) with each missile being capable of carrying 2–10 separate nuclear warheads. Each warhead can be assigned to a different target, separated by hundreds of kilometres; alternatively, two or more warheads can be assigned to one target. MIRVs ensure a credible second strike capability even with few missiles. According to DRDO sources,an MIRV payload would be significantly heavier, since it would consist of several nuclear warheads, each of them weighting about 400 kilogrammes. A 5-warhead MIRV, therefore, would weigh two tonnes.
