Re: Indian Missiles News & Discussions - 17 Dec 2018

The fact that we are now flight testing HSTDV, means atleast basic technical hurdles have been crossed and there is political approval (and funding). So now all we have to do is increase the pace of testing, while our babus do their usual thing. Delaying discussion over chai biscoot.. Can't really ...
