Personally, i would rather we develop our own 500 km subsonic missile. Taurus is freaking expensive, too expensive for the huge number of targets we'll have to engage if we have to fight both china and Pak. What we need is an inexpensive subsonic missile with a range of 500km, with similar warhead capability as the Nirbhay which should be it's larger cousin, They should just scale down the current Nirbhay down to a smaller missile and you get a mini Nirbhay with the same 24 warhead capability and low weight. For the likes of our enemies, we'll need huge stock, a mini Nirbhay missile inventory of around 3000 missiles and another 2000 normal Nirbhays.
Nirbhay would have a range of around 1000km, weight is expected to be around 1200 to 1500 kg and is expected to be able to deploy 24 types of warheads. I am sure they have been working hard to keep the weight as well as the design as stealthy as possible. It should be fairly easily to take the same well researched design and turn it into a smaller cousin weighing around 700 to 900 kg with a range of around 500 km. the smaller missile should be easily deployable from the Mirage, FGFA, MKI, mig-29, LCA mk 2, Jaguars and off course MRCA.
