What is the status of SANT?

Any flight trials so far?

 

[Bhadra]

Just a humble request . Please don't humiliate yourself considering that you think IIR is old tech.
Which ground launched fire and forget ATGM of 4km range has MMW seeker ?

Asking question on my question... ??

Ok no one has made it. Does that mean DRDO should not make it ?? Do the things work like that with DRDO??

For your satisfaction[

"A passive imaging infrared (IIR) homing seeker guides the missile to the target after its launch in all lighting conditions. The missile can be optionally offered with a millimetre wave active radar seeker. ""

Nag Anti-Tank Guided Missile - Army Technology

Nag is a third-generation, fire-and-forget, anti-tank guided missile developed by India’s state-owned Defence Research and Development Organisation (DRDO) to support…

The unibody biomimetic design with advance release technology is a lethal combination for surveillance missions".

Can "a unibody biomimetic design with advanced release technology" be a hexacopter or a quadcopter?
Hmm....makes me wonder
And then there is the stealth conundrum.

 

[Bleh]

Ok let's pretend you're actually interested in facts.

What is the time of flight of the missle for 4000 m ?

Varies from model to model. This series have max speed of max 250m/s, so minimum about 15sec.

Can a tank and fired at 4000m go behind a mound before the the time of flight and become invisible..

Not from a top-attack ATGM.

If yes. then what does the seeker do ?

Anything without top-attack or not being laser-guided from drones will miss.

Second question - after firing the missile there is a dust storm between the missile and tank. Now how does the seeker keeps a track of the tank... ??

Such magical dust storm (more practically smokescreen) can effectively block laser or visually targetting missiles & reduce heat signature of targets.
All top-attacks have best chance of maintaining lock.

NO, it is not a BVR air battle and there are no stnad off ranges involved.

The function of Ground lauched ATGM is to be able to engage a target at maximum range of Identification, acquisition and tragetting and retain that ability till the target is at minimum range.

NAG is basically a Recce and Support Mech Infantry battalion weapon primary used in Defensive operations. Thus it has tactical requirements under which minimum range becomes crucial. IF NAMICA falls back from forward zones to defense line behind a minefield and is not able to engage a tank charging on defenses at 400m away then DRDO might store those missile at MetCalf House.

The weapon to cover the dead zone of NAG is 84mm Carl Gustav which has an effective range of 350m against a moving target,,

NAG initially had a minimum range of 700m and they claim that it has now been brought down to 500m.

I do not think that should be acceptable unless it comes down to 200m. I do not know the GSQR though.

All of it is incorrect... This is not 1970. Range of engagement is higher. Loitering drone-munitions on the verge of recognising enemy armour by themselves whittle any need of user guidance.
Similar to the AI of pilot's HMS system.

 

[Indx TechStyle]

Members better keep their discretion in mind while debating. Argue in technical terms or don't argue at all, especially with ad hominem and strawman arguments.

Kakrapar Atomic Plant-3 achieves criticality.

Prime Minister Narendra Modi on Wednesday congratulated nuclear scientists for achieving criticality of Kakrapar Atomic Power Plant-3 calling it a 'trailblazer for future achievements.' The 700-MW pressurised heavy water reactor has been indegienously designed and is a shining example of the efforts of the Make in India initiative, added PM Modi.

Commissioning of Kakrapar Unit 4 likely by 2021.

Last year, Union Minister Jitendra Singh had announced that India will commission one nuclear reactor every year from 2020. "We will commission one nuclear reactor every year from 2020. Kakrapar-3 should be commissioned in 2020," Jitendra Singh told reporters back in December.

A senior official said the fourth unit of the Kakrapar power station would likely to be commissioned by 2021. The Nuclear Power Corporation of India Ltd (NPCIL) has 22 reactors across India and is the only agency to operate such plants. The Department of Atomic Energy (DAE) is responsible for overseeing atomic energy policy in India.

Kakrapar Atomic Power Station

Kakrapar Atomic Power Station or KAPS is a nuclear power station situated near the city of Vyara in Gujarat. The atomic power plant consists of two 220 MW pressurised water reactor with heavy water as moderator (PHWR). KAPS-1 went critical on 3 September 1992 shortly after which it began commercial electricity production the following year. KAPS-2 attained criticality in September 2018. The construction of units 3 and 4 started in November 2010 with KAPS-3 achieving criticality in 2020.

Who are you kidding?.. I literally caught you lying through your teeth several times, for both vintage tech & foreign maal.

Only a few days ago it happened again. Sharing again if anybody had not seen it yet.

The South African version weighs about 20 kg and this Iron piece is about 40 kgs.. ammunition still has to be imported..

Uncle this is not 1970, all information is available on this new thing called Internet... Think before you lie.
(Quoting the rest he has misinformed.)

Compared to Denel NTW-20 rifle on which it was based on.

Not from a top-attack ATGM. Anything without top-attack or not being laser-guided from drones will miss.

Missile will carry out top attack when it is able to continuously acquire image of the targets. IIR is no search and Seek. It is running to a locked on image...

Such magical dust storm (more practically smokescreen) can effectively block laser or visually targetting missiles & reduce heat signature of targets.
All top-attacks have best chance of maintaining lock.

In the battle field where there will be say minimum 14 -15 tanks advancing with similar numbers of other vehicle on a terrain where a single jeep kicks up unimaginable dust . if there is no dust storm and one gets a clear line of sight - that would be rather magical..

That. however does not diminish importance of any technology.. those are unmitigated features of the battle space..

What is the point... I do not know what vintage of system you quoted and from where .. bothe are dead weight and not in use by the Army... 20-30 kg AMR is a dead weight...

But if the point is is that I am a lier so be it... how does that matter to you .. you certainly are not a certification agent.. nor an authorized moral arbitrator...

Your quoting that Ram Kahni has no relevance to this thread.. and the subject... the fact remain you guys are hood winking on the current topic including you..

I had asked another question if the OFB makes that ammunition which you coolly ran away from.. Now I have caught you SOB is a game I do not play..

This is not 1980. If you don't fully comprehend how modern tech works, then do not make expert comments. Ask.

Modern IIRs are smart enough to evade flares & identify heated tanks against hot desert sand (this was what SPIKE failed to do in desert trials, NAG took several years of work to meet this requirement).
Top-attacks don't ruch straight at the target. Smart weapons can even reacquire targets & AI tech is reaching that level where loitering ammunitions, launched in the enemy's general direction, can acquire & engage targets on its own.

In the battle field where there will be say minimum 14 -15 tanks advancing with similar numbers of other vehicle on a terrain where a single jeep kicks up unimaginable dust . if there is no dust storm and one gets a clear line of sight - that would be rather magical..

Like this?.. Yeah no problem.
Line of sight of direct fire weapons may be hindered, but top-attacks & loitering ones will look at it from an angle the camera is. And as you see they're pretty visible from here.

I had asked another question if the OFB makes that ammunition which you coolly ran away from.

OFB's incapacity part was not a lie. Nothing to rebutt there... But the 20kg - 40kg was a massive false claim.
Nothing personal against you, but some people might have believed your words to be true. So I had to interfere & let them know that you can't be trusted as an honest source of information.

We are talking of the problem of acquired image at lock on which the seeker then continuously keeps acquiring and comparing to maintain flight path. You are trying to take me to flares and what not /.. Nag or Spike failed because the seeker was unable to maintain lock on on the target due whatever reason..
I painted the same scenarios in different context and you are simply hood winking me ...

A real-time image processor with fast and efficient algorithms is installed next to the guidance section to provide automatic target detection and tracking capabilities. The digital autopilot offers guidance, stability and control for the missile during the flight.
There is no camera angle scene here which you are trying to peddle/

Top attack capability is the ability of the missile to change the course of trajectory at terminal phase and make the missile land vertically within the limits of lighting condition and traceability of target with in seekers angle of visiblity.

Rest all you mentined is called "throwing names". I assure you, hoodwinking is worst character trait than lying..

Like this?.. Yeah no problem.

The weapon acquired during Kargil was proven useless. OFB made many versions and was rejected by Army. It now exist with BSF mounted on a modified stand on BOPs and is more than 100 kgs overall. soit has now become 100 kgs.. so what ??

Truth or lie is immaterial. The massage was coveyed and who cares for you. I am not giving any exam to you . Am I ??

 

[utubekhiladi]

No it isn't. But it's not a true SALCOM either, but has that option to handle such cases like he mentioned above.

could you plz explain to me in detail

 

[Chinmoy]

Tilter cum " launcher " is even more interesting

Yeah. Best for container based system.

The "whatever reason" is maintaining IIR lock on heat target with the landscape all around it being of same temp. is hard for a sensor.
The flares were mentioned to explain the decision mating capability of the guidance softwares in modern ATGMs vis-a-vis you incorrect assumptions that they home in straight at the target.

You sir, should work on your comprehensive skills beside acquiring basic knowledge on these tech (not addressing the rest, they're all wrong & you'll find the data on internet).

And about calling out your lie... as i said, I only had to make sure other people knew that you are not a trustworthy source & your claims can be 100% false. Or they might believe those to be true. Couldn't let that happen.

could you plz explain to me in detail

Manual command to line of sight or MCLOS are the older but jam-proof wireguided missiles, which are basically flown to the target by the operators.

Semi-automatic command to line of sight or SACLOS is the case where you laze the target & the missile homes in.

NAG is Fire&Forget but IRguided ATGM need as heat signature to track-while-maneuvering & home in to.

BUT if a dug-in tank was waiting all night with its engine off, or is driven under the midday sun of Thar, then its metal body would be of the same temp as the ground around it... So the missile's guidance system have trouble holding lock on it. In such situation laser-guidance has been opted for to guide the missile to the designated target.

Is not ideal. As it will unfortunately be direct attack & guiding lasers from operator can be blocked by dust or APS smokescreen. Meaning unlike loitering or maneuvering F&F warheads that may reacquire the target while maintaining level flight around it.

Hopefully it's just an alternative option. I'm not sure yet.

are u saying nag have both IR and laser seeker? i m now more confused.

Not NAG, but it might be optionally mounted in Helina's version called Dhruvastra... for versatility.

Follow-up.

It's easier to hide behind smoke or topography from direct attack mode:

Much harder to give from top-attack ones that'll dive in from high angles, but must be F&F with something to track:

If the Missile is going to be fired at direct attack mode, then older wire-guided is actually the better option, what a skilled operator can actually turn & bypass that smoke or silhouette... Unjammable too.

Beside that, best long-range option is loitering munitions where you launch the ATGM in enemy's direction & chick off. It glides towards them while taking secondary guidance from battlefield surveillance radars. Based on that it identifies the target signature from various angles & swoops in to engage. Very hard to detect launch (because of long range) & offers no warning to the sensors on the target tank or helo.

But AI needs improvement. It's still experimental tech.
