And they had shown Brahmos-2 hypersonic variant scale model in 2013 Defexpo. Seven years have passed and still Dr Mishra is saying that it will take another 2-3 years for a high supersonic Brahmos and 4-6 years for a hypersonic variant .
Back then in 2013 the understanding was that Brahmos 2 will have Russian engine (the one on Zircon missile). However, now that HSDTV scramjet has been tested successfully by DRDO (it will take another 4-5 years to be matured to be put in a missile), the current plan (as revealed in the Shiv Aroor interview) is Brahmos 2 will fly using indigenous engine.

I guarantee you it won't. Indigenous engine will be nothing but russian tech transfer under the table.

Why would we put our scramjet engine in a missile developed by a company that is 49.5% owned by Russia?
Instead, DRDO will build another missile based on that scramjet engine completely in-house. If Russians don't like sharing their crown jewels, why should we?

Zircon has undergone many successful user trails both from a Tu22M3 and surface vessels. The latest launch was from Admiral Gorshkov.

We could have gone for some initial nos of Zircon to maintain that qualitative edge before our own scramjet is ready and available for use.

So yesterday's missile test firings were a coordinated exercise between IAF and IN.

The Brahmos ALCM hit the retired INS Cannanore shortly after she was hit by a Uran missile from INS Kora .

The Su-30 had taken off from Halwara airbase . The Pakistanis are surely feeling the heat . Im the Dim and his brown panted masters must be quaking in their boots.

Shilka weapon system

Adavanced l70 developed by bel

This new weapon system sports a new electro-optical firing control system, offering a computerized fire control. It also has a day/night vision mode, automatic target tracking, as well as a muzzle velocity radar.

The gunner behind controlling it now has a video display, which controls all of the firing operations. The gun carriage is upgraded to have a state-of-the-art electric drive, with a 10 hour-operation battery. Except this, Bharat Electronics Limited also developed a computerized simulator to train new gunners, by using video output of the computer connected to the video display.

Air Sterilization Unit (ASU) for Submarines by DRDO.
I believe it is part of the submarine onboard scrubber system , not a standalone system.

I once posted the pic of the same being used in Indian nuclear submarines .

Generally if the scrubber fails and the submarine is not able to surface , everyone's life will be at risk more or less.

It is a critical life support system needed to keep the onboard air fit for breathing by removing CO2 and CO.

It's basically a system for removal of bacteria and viruses from air. It is compatible with air ducting already in place. Has spin-off applications in bunkers, hospitals, theatres, malls etc.

Different missiles have been labelled as MLPGM over the years. Has caused lots of confusion.

Has there been any test of this missile? What is its maximum range? 10 km will be more than enough.
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.

Hmm
In light of this maybe it is a standalone system and to be fitted as a additional safeguard because a submerged submarine especially a nuclear one already has a close circuit air circulation system with a highly efficient filtration ( scrubber ) system.

For a long time DRDO was working separately on radar absorbing materials and frequency selective surfaces ( FSS ) for application in stealth aircrafts.

Recently they have started working on combined radar absorbing material and FSS. It allows the new stealth material to allow the transmission of the desired frequency band from the enclosed radiating modules while at the same time out of band frequencies incident on the material are absorbed.

Long story short the material can be used to make coverings ( eg nose cone , T/R aperture etc ) of onboard transmitters which will allow the specific frequency band of the transmitter to pass through while at the same time act as a radar absorbing material for other frequencies coming from external sources like hostile radars etc.

@Arihant Roy
Last I heard of in June 2020.
1. IIR and MMW seeker miniaturised.
2. Control surfaces miniaturised.
3. Grid/Lattice Fins to be used.
4. High speed data link under development.
5. No tests conducted as of now.
6. Probable earliest test date is late 2021.
7. Range would be similar to SANT.
*Open source.
