As I said previously MLPGM has been tested twice atleast.

From lakysha drone ( video available on YouTube delhi defence review )
From mirach drone ( pic available in trishul blog )
I shared what I knew about it. Not disputing anything you say. Given your assertion about the tests, I did try to look it up. Landed up with this piece from Bharat Rakshak. It's a piece from Dr. V.K. Saraswat's presentation in 2014 (maybe it was tested after 2014). It does mention that MMW seeker based PGM is under testing. However, dosen't say that missile launched PGM is tested or testing.... just says that it's possible to bunch it up in Prithvi missile.

Open source evidence points to atleast 2 test-fires from drones ( mirach , Lakshya ) , there maybe more .

Range I don't know , will depend on the release altitude.
So, then we really have a non strategic cheap armed drone program ?

Lakshya is a target drone and its relatively cheap.. ok I confused the munition with SANT
If you are talking about using Lakshya as an armed drone. It's already tested for that.
"Lakshya Weapon Delivery Configuration is also developed for weapon delivery at known Coordinates. The tow bodies in Lakshya-2 Weapon Delivery Configuration carry High Energy Weapon Payload. Ballistic, Unguided weapon delivery is achieved using Cotntinuosly Computed Release Point (CCRP). 9 Lakshya Weapon Delivery sorties have been completed with 16 weapons (4 Live) dropped."

DRDO initiated the development of Self healing materials along with some other advanced materials such as Stealth materials, Sensor materials and other smart materials.



This link explains the basics of Self healing materials

As per my understanding it's a Drone launched PGM, not a MLPGM. MLPGM would be stacked/bunched up inside the body of the missile and seeded in the target area, in the terminal phase of the missile.
For me, the pic represents a PGM test but not a MLPGM test.

Look like they just change the manned turret on Arjun with an unmanned one. Moving crew in thick armoured capsule in front. But there is only one hatch. Look more like a recently upgraded chalanger 2 front.

Ground clearance looks pathetic for such an arrangement. no crew escape hatch underneath.

Compared to T 14 Armata. Since this tank aspired to be similar.

Better ground clearance + crew escape option from beneath.

The test would broadly fall under the MLPGM program. But what was tested and proven was control and guidance algorithm of the munition with mathematical model of seeker. As can be seen in the pic, I still stand by what I said previously. It is a PGM, not a MLPGM.
It's a PGM launched from a UAV, not a missile.
There is a difference between validating a sub-system and validating the system itself.
Let's agree to leave it here.
