I Googled around and found some images. I see what you are saying. Yes - absolutely, Nirbhay will have lower RCS than these previous THK designs. Its interesting that THK Blk IV, which has loitering capability was first tested only in 2002. If Nirbhay already has it, it means we have made several generational leaps and caught up within a decade of Khan. Not bad at all!
Thanks for letting me know. I've moved the image of the older Tomahawk in my earlier post to imageshack.
Regarding loitering, I found something very interesting regarding the "Quick Strike Tomahawk" or QST and its loitering capability:
[Speculation] What if the SDRE scientists tested a S-shaped set of waypoints within a short range, as if testing obstacle avoidance, in the very first flight test and the onboard navigation computer had a "does not compute" moment? Unspeakable's Google Earth picture above does show that the navigational error originated at the knee point in the route. Perhaps that knee point was not a neat single change in orientation but a more complex obstacle-avoidance route. Although I would think that the problem in the extract above would've been simulated and resolved, it's still possible if the waypoints were updated midflight and the route had to be autonomously computed by the onboard navigation computer.
