DRDO and PSU news and discussion

[Dessert Storm]

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.

 

[Shashank Nayak]

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 ?

The discussion was about Missile Launched Precision Guided Munitions, not 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."

LAKSHYA-2 | Defence Research and Development Organisation - DRDO|GoI

Advanced Pilot less Target Aircraft - Lakshya-2 is an advanced version of Lakshya-1. It is a target for weapon systems like radar guided and heat seeking Surface to Air missiles, Air to Air missiles. It has a Scoring systems capable of calculating the miss distance of the weapon accurately. This...

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

Self-Healing Composites for Aerospace Applications

In such composite sciences, recent advances have thrust self-healing materials into the limelight. Such innovations could pave the way for many applications , especially in the aerospace sector. In aerospace applications, self-healing composites are likely to be an significant component...

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.

Probable frontal profile of under development NGMBT.

Probable frontal profile of under development NGMBT.

Is crew in front ? I see only one hatch. No Hard kill APS, no screen to protect gun and electronics etc. RCWS is over gun mantlet lol , any specifications about this.

 

[Swiftfarts]

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.

 

[Swiftfarts]

So i made a mistake RCWS is in back , not on mantlet. crew is still in turret. Basically Arjun Mk2.

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.

Look like Koreans have transferred there tank turret design.
