(1) Currently there are no Air to Surface missiles that are even Supersonic, so it is not possible that they may become hypersonic.
(2) Even Surface to Surface missiles barring Oniks/Brahmos is Supersonic.
So we are left with
(1) Surface to Air Missiles that are Supersonic - SM3, PAC 3, S-400, Arrow 3
(2) Air to Air missiles that are supersonic
(3) Re entry vehicles of IRBMs, ICBMs
Ergo, which missiles will be replaced by Hypersonic missiles ?
