If to be believed what chaiwaal posts in some forums, they quote this range.....i don't remember which forum it was, he had done calculations of range of Nirbhay missile with some Russian gas turbine engine....He says if at all Nirbahy is 1500kg-2000kg class missile then the range willbe 2500km - 3000km based on the fuel consumption of the Gas turbine engine when the payload is 1 ton...he also states that Sub launched will around 1000km -1500km with one ton payload....
IS that Russian engine thing came from Chor guptas blog?
Because GTRE already developed a mini kaveri for powering UCAVs and Cruise missiles.Its called LAgu Shakti Engine with 400Kgf thrust.
For people wondering what this 400Kgf in terms of newtons,400 kilogram-force = 3922.66 newton i.e ~4KN.
For a comparitive purpose Tomahawk BlockII using F107-WR-402 with a thrust of 3.1KN has a 2500km range and weight ~1600kg carrying 450kg warhead.
Given the Indians obsession with more and more payload carrying capability, LaguShakti with 4KN can easily carry 1tonne to ranges in excess of 2500km with all up weight of little over 2300kg.
IF the actual reports are true, the Nirbhay initially will sport 2 varriants one with 300-500kg wahread and 1000km range and second one with above mentioned details.
And while coming to PRahaar, Saraswath said that it reach a peak altitude of 35km ~5kms more than the normal AAD ceiling.This means Prahaar will rise to 35kms with speeds of MAch 4 and then follows a parabolic path towards the target. IF my assumptions are right, then atleast 3/4th of its flight will be a powered flight when a range of 150km+ is considered.
Anyways,since the tech is our own and not borrowed from any other country, we can bringout as many derivatives as we wish for.Maybe an AShM for small ships of corvettee size?
( ooops for some countries their capital ships like destroyers are of similar size like our modern corvettees)
