Agni-VI

Agni-VI is an intercontinental ballistic missile being developed by the Defence Research and Development Organisation (DRDO) for the use of the Indian Armed Forces
Agni-VI will be a three-stage intercontinental ballistic missile, which is in the hardware development phase, after its design phase was completed. Agni VI is expected to have Multiple Independently Targetable Re-entry Warheads as well as Maneuverable Reentry Vehicle (MaRV). And these maneuverable warheads will give Agni VI an extended range exact figure of which is currently classified. It will be taller than its predecessor Agni V, and is expected to be flight tested by 2017
Till 2009, it was reported that the Government of India had not considered the development of an ICBM with a range of 10,000 km or above. Speculations of an ongoing program for a longer range ICBM resurfaced in 2011. Some reports claimed that the ICBM is already named "Surya" and code named AGNI-VI
In October 2011, a report published by The Pioneer raised doubts about DRDO's ability to independently develop the "seeker technology" (guidance technology) eligible for ICBMs, that could enable the missile to traverse long distances in excess of 10,000 km. The same report also asserted Russia's willingness to provide India with help in the field of "seeker technology". The authenticity of the pioneer report is disputed by at least one foreign newspaper, with the counter-claim that the involvement of Russia is probably inflated out of proportion, because if the report about Russian involvement is true, Russia may be suspected of violating the Missile Technology Control Regime
The SLBM version of missile will arm the Arihant class submarines of the Indian Navy. DRDO revealed in 2012 that it is also in the process of developing another variant of Agni-VI missile. This will be a submarine-launched solid-fuel missile with a maximum range of 6,000 kilometres and a payload of one tonne
