This whole Shourya saga is creating some confusion
what i understand reading all these articles is that
a ballistic missile leaves the atmosphere,re enters then descends towards the target
but
in case of Shourya it reaches 40-50km at Mach 6,then it does not leaves the atmosphere but moves or "cruises"
towards the target burning own fuel then it descends towards the target at hypersonic speed and it can do maneuvers in the descend phase and also correct it's trajectory by Ring laser gyroscope and terminal guidance unlike normal ballistic missile thus making it more accurate.

Well even Agni has guidance and correction package as it descends before or after it re-enters atmosphere.
What Shaurya does is unusual/tricky maneuver, in being able to sustain its relatively long flight below 100 km atmosphere enveloping earth surface. Prithvi did this all these years without leaving atmosphere, as its apogee was ~85 km, and its mid section wings and tail fins allowed it to maneuver as it came down, even fly horizontally at ~ 20 km altitude before diving steeply to hit target at high infliction angle.
From Ajai Shukla's interview of Saraswat, Shaurya also try to emulate a similar flight, instead of flying high to 80 km altitude it did a gradual climb to ~ 40 km and flew almost horizontally in that rarefied atmosphere, making use of the body lift, and losing potential energy to sustain hypersonic regime speed most of the way down.
With Shukla's article what is not clear yet is if Shourya is a classical BM and is also capable of performing aero-ballistic trajectory, or if Shourya is a a dedicated aero-ballistic missile incapable of classical BM flight ! And we will positively know which one of the two it, when burn duration of the second stage is known.
That got me stumped too.
What is shown in DefExpo is the same article that rolled past Raj Path on 26 Jan, and that missile is simply a dummy model where the nose cone is cheaply rivited with a L plate the outer container can be clearly seen. {same as BrahMos demo missile in earlier Rd parade and Aero-India shows}. I had mentioned the RD parade nose shape issue with a distinguished India Forum member too.
Bottom line, we will know once we get more high res pics of future flight test, and confirmation of second stage burn time.

Quote:also the nose cone of Shourya in the November 12, 2008 test and the nose cone shown in the defexpo 2010 seems to be different can anyone tell about that.
