AVATAR is an even longer way off!
I agree that it IS...but you must agree TO the basic fact that AVTAR is not a missile, and its even more complex than what you think of missiles because it is single-stage REUSABLE Rocket plane capable of horizontal takeoff and landing. If DRDO has quasi perfected a Scramjet for that, then it speaks volume for your answers to be delivered. Because single-stage REUSABLE rocketplane capable of horizontal takeoff and landing is a complex technology akin to space shuttle, missiles are not that complex to maneuver.
BTW, in a BrahMos-II, wouldn't the Mach number of the flow into the scramjet exceed Mach 2? Just asking!

Yeah, I know of these two limits. However, my initial guess is that a scramjet for the BrahMos-II should be designed so as to accomodate flows at least upto Mach 3+ into the combustion chamber. I'll verify this figure when I find some time, but the scramjet certainly needs to be designed for input Mach numbers > 2. Incidently, I know what AVATAR is (or what it is protrayed to be) and it's more than a couple of decades away, or even much further than that, given the streneous work ethics at DRDO!
BTW, your statement If DRDO has quasi perfected a Scramjet for that.... doesn't mean that what is most likely a proof-of-principle experiment on scramjets by DRDO comes anywhere close to perfecting a working and reliable scramjet for the Brahmos-II let alone the AVATAR! Incidently FYI the precise flight envelope of the AVATAR hasn't been finalized.
