And this is excerpts on A2-AT from by missile page that was previously posted on BR.



Sorry I have been so busy I have not yet hosted my material somewhere else for greater public good.



Recent reports suggest 1.3 meter diameter. And I think this missile was secretly tested in early 2010, and with Ballistic Glide RV. Let us see the actual dimension when the fat lady sings tomorrow.

Some more excerpts from above article of mine:

Agni-IIAT Configuration

----------------- Agni-IIAT Stage 1 --------- Agni-IIAT Stage 2 --------- PBV/HAM --------- RV



Number of Engines ---------------- 1 --------- 1 --------- NA ---------

(Number of Segments)1 --------- (3) --------- (1) --------- NA ---------

Each segment contain one grain of composite solid rocket fuel.



From the higher resolution photo it is clear to me that

1. the second stage is 1 m diameter composite, that is almost identical with Agni-II second stage, composite case, higher enegry fuel and flex nozzle.
2. Booster is a 2 segment construction, instead of my anticipation of 3 segments. (see those thick weld like lines in the middle of stage). fewer segments make is cheaper.
3. Booster also has flex nozzle for good control force availability in all speed range. Something that Agni-II with no flex nozzle and fins did not have, and would have limited its ability to be launched in rough weather conditions (windy weather).
4. Inter-stage is closed (as against vented in earlier design). One can see orifice for retro rocket at the top edge of booster stage. patc
5. The RV has many conformal antennas (patch and slot antennas) and apertures that speaks of all intelligence and sensors on the RV and mission computer. All teh way from range safety, instrumentation, multi sensor fusion (looking at ground below) during hypersonic glide/terminal manuver.
6. From the picture the RV looks different from Agni-III RV.
7. Lack of fins makes it suitable for canisteried packaging, that provides protection from unauthorized access, transportation elements, controlled passivated gas environment for longer fuel shelf like and reliability, as well as ability to make many cheap decoys.
