all I know is that military heavyweights such as US, China Rusia look down on supersonic missiles such as CX-1 and Brahmos, except after they evolve into sth hypersonic (such as > 5mach).
This is because they are almost useless and not a real threat to other big boys with advanced AESA radar-equipped destroyers supported by AWACS, drones, sats, ... a full range of pre-warning systems.
That's why the US, Chinese and Russian navies prefer advanced low-flying "assasins"- sub-sonic missiles in general, and export supersonic ones.
Nonetheless for countries like India missiles such as Brahmos are still the "god"... the "god" prior to the arrival of the
"super troll of the year CX-1" of course
CX-1 and brahmos are in general comparable on paper, due to their common ancestor - we all know who that is.
However, between these two, I'd buy CX-1 anytime of a day, cuz more reliable, more mature, more quality and likely even cheaper, lighter, even with better paint! and ... i've never heard of anything good from Made-in-India even with TOT by Russia. Actually the only thing that coming from India that can fly is the holy cow, as far as I am aware.
and BTW, another thing perhaps even more important : Brahmos uses GPS - needs permissions from both Ruskies and the Yankees when it really matters, while CX-1 is Beidou- guided.
