OK. So it looks like AD-1 or AD-2 missile could be based on Shaurya SSM. Shaurya SSM is 6.2 tons and 10 meters long. The poster below lists SLS capability as "launching articles of up to 7 tons weight" and a loading mechanism: "highly accurate 10 meter long article guiding mechanism". Another poster on the blog (source linked below) shows diagram of the loading mechanism in action.
Shaurya SSM has a lesser throw weight at 1 ton compared to 2.5 tons for Agni-1 (both at 700 km range). Agni-1 booster used on the PDV Mk-II missile used for anti-satellite test was later confirmed capable of taking out targets upto altitudes of 1200 km. Which means AD-1/2 missile is not going to be able to fly to those altitudes. But it still might be capable of reaching lower parts of the LEO (Low Earth Orbit), thereby giving AD-1/2 missile limited ASAT capability.
The satellite pics show 4 SLS being fitted onto the DRDO ship. So maybe they plan to test out AD-1/2 missile capablities against a salvo of ICBM-trajectory mimicking missiles?
What about the radar?
@porky_kicker do you know the range of that Dual Panel Long Range-MFR being installed on that ship? Is it comparable to LRTR Mk-II? Is LRTR Mk-II even operational?

As an aside, in the Prasun Sengupta blog post I linked above, he misinterprets the posters of the company that manufactures DRDO designed missile launchers. In the last poster on SLS, three different launchers are shown. One is SLS, then Akash (possibly NG variant) and then the Tilter-cum-Launcher (ADV MkII launcher). He then proceeds to explain how SLS has a "variant" to launch the Akash NG. Earlier he calls SLS a "universal" launcher.
Earlier, when I used to read his blog, I thought he must have some sort of insider information or something. But looks like not only is he quite clueless, but also very poor at basic comprehension.
