Well we have to wait for that to be sure. Test will begin this year. If either you or me is correct , both will be good news lol.
The astra mk2 model which you posted if it is to scale , then the position of fins don't match, neither the tapering of the nose cone nor the length of the fore section.

If you noticed, NGARM and Astra mk1 kind of look same so.........

Also this one with grid/lattice fins is interesting, it will be funny if it ends up being a air to air missile ( Astra mk2 ? ) rather than a air to ground missile which I am guessing.
