The photos and launch video clearly indicate it is the K15 Sagarika a variant of Shourya.
Some news report inadvertently spill out the true range of this missile (not the oft quoted 700km reports) as 1500 km.
Pallav Bagla NDTV mentions seeing teh missile trajectory whereby it goes up and down and up again. Its the classical porpoise maneuver that this hypersonic Cruise Missile is capable of doing.
My observations:
1. This missile test was done for the classic hypersonic CM where missile stayed in atmosphere all the way. Range was 700Km.
2. One can clearly see the booster separation just few seconds after liftoff.
3. See the small boats near launch point, compare it with missile length of ~ 10 meters.
As I have shown earlier the missile can also fly ballistic and resume CM on re-entry with minimal re-entry load, and that range is well in excess of 700km (pure CM ) range, expected to be at least 1900 km.
See page 14 and 15 of this PPT that I shared with some friends couple of years ago.
