Akash Prime is in production.The original akash is also ramjet based right?
According to your description. Akash NG seems to be more advanced than Akash P. Yet both missiles are in testing simultaneously, and Akash P has never been ordered. It looks like Akash NG will be ready as well by the time Akash P is ready. So Akash P may never be ordered.
Hence my question. Why is akash P being developed in the first place?




















. That's because Ramjet needs to feed air to sustain its power, while dual-pulse missiles like Akash-NG carry oxidiser within their propellant grain, hence can be lofted to much higher altitudes where air-density is really thin. So, that's why theoretically MRSAM/Akash-NG has twice the range of Akash/P while having half of its weight.
