Not really, Please look up on Agni a bit, the Agni 2 and AT ranges was always underreported, true range being told by some biographies, and the Agni 3 is a new platform altogather to develope a new generation of missiles, in that sense Agni 3 with 2 stage is the precedeeser of the full fledged ICBM Agni 4 with a third stage, the Agni 3 already has more than 5k range [mentioned in host of interviews], it was tested in dampened trajectory, something of which you can make out if you see the launch pictures.

Range is a non issue for India, but this Sagarika range is a bit puzzling, lets wait for whats actually cooking. 700 kms doesnt cuts the ice or is enough to do the job…

I have done plenty of ‘looking up’ on Agni.
