Kh-31P is an AShM which is RAMJET powered and make use of liquid fuel. Due to its engine its going to be heavy. As @NeXoft007 mentioned, with 60 kg warhead its no way going to be of 140kg overall weight. But if we have to compare something contemporary, it could be compared with AGM-88 in case of warhead. It too have a warhead of 66 kg. But it does have a longer range of 150 km as compared with NG-ARM at 100 km.
So it should weight less then AGM-88 in common sense. But unless and untill we get the dimension of it or any official source on its weight, it would be a speculation.

Any official spec poster quoting the range of NG-ARM as 100km? Sorry, I am not aware of it, but it seems the range of 100km came out after someone said its similar to Astra months back.

We have novator k-100 missile

Not quiet sure. Actually as per what had been published in DRDO publication, its range is 60 Km and it weighs around 140 kg. No mention of warhead had been made thou.

Is NG Arm a missile or a glide bomb? Glide bomb can strike only ground targets while missiles can even strike AWACS.

I was watching an interview of ex commander of western air command.

He said with s-400 and novator missiles we can deal with Pakistan.

This was last year.

Its an AGM. It could only target AWACS only if fired from enough elevation. But theoretically it can't be used against an AWACS. We need AAM for that.

Could be a typo error, but NG-ARM is 1.5m longer than Astra (Pic 1) and it has 60kg warhead (Pic 2). Astra itself weighs 154kg, its impossible NG-ARM would weight 140kg when its longer and have a much heavier warhead than Astra BVRAAM.

Its quiet logical. But there is one more aspect to it. ASTRA is an AAM, so does need a heavier engine and more fuel to provide thrust. But NG-ARM being a AGM, could do away with a less powerful engine and less fuel. It would not need to carry on some drastic G maneuver only some small path correction while maintaining its slant path. So keeping all these in mind, 600kg too seems to be too much. something around 250 to 300 is more logical IMO.

BTW you have any info on its engine?

An air to ground missile only needs to glide or fire small motor. There is a requirement of powerful motor for BVRAAM missile as it has to stay afloat without losing altitude, chase, maneuver to catch enemy aircraft. BVRAAM needs big and heavy motor with lots of fuel while NG-ARM doesn't need it

So it's like an undisclosed procurement and a surprise for Pakis like Styx during 1971

Right.

This interview was recorded in July or June 16.

The topic was single engine jet deal and dwindling squadron numbers and how can air force manage the threats with current technology and jets.

He said as per mmrca we had to buy 126 jets but we are settling down for only 36.
He said it's a mockery of the tender and gormint should buy about 60 more rafales so that maintenance is worthy.
Buy another 100 of jets single engine jet or whatever,and buy some 200 tejas's.

That will boost indigenous industry as well as the airforce ability to conduct operations.

He also mentioned Tejas at best is a point defence platform,given its very small combat radius and dismally small payload but the program is necessary for local military industry.

One thing he mentioned is what I really admire that he mentioned that air force if supported by a strong and sustainable supply line can click 6 sorties per aircraft per day.And ultimately sortie rates is all what matters.

He talked like a proper visionary.Like adding a strong network based communication and command,addition of long range vectors, opening up ALG,addition of force multipliers such as AWACS and tankers and heavy transport aircraft,using a more offensive strategy to gain upper hand in any conflict.

Isn't 60 km less. Even glide bombs are able to cover larger distances at appropriate release hieght with a bulkier body. And why is it called nagarm? What's the next generation part in it?

 

[Adioz]

Someone please help me out here.
If NGARM is indeed an air-to-ground missile, then why does it need a dual-pulse propulsion? Why does it need to maneuver at the end of its flight? A ground target is not likely to evade is it?

How it would do any last minute adjustment if it has to? And moreover battlefield TAR and FCR are mobile unit.

Glide bombs are stand off weapons which are used against stationary targets. ARM are standoff weapons which are used against stationary as well as mobile RADAR unit.

 

[Adioz]

It has a passive seeker and would take two minutes to reach its target. The target stops emitting when it moves, so the seeker would not be able to home in on the target, unless it has an active seeker as well. Also, how long would it take for a FCR to move? If it takes more than 2 minutes, its not going to be able to move before the missile reaches it. What am I missing here?

Adioz , one of the problems with SEAD is that when you launch a missile towards someone's RADAR is that they can and will detect the launch, the time interval is dependent on enemy's sophistication.
Two approaches;
Loitering weapons, e.g.- HAROP and Harpy, loiter in their area of operation, so when a RADAR scoots 10 or 20 kms and starts emitting again, you are already in the vicinity, percentage of a kill increases.
Such systems are not reusable and costly.
Other approach is that you fire something really fast, H in american HARM stands for high speed. It is faster than their AAMs. You will note that DRDO didn't put a dual pulse motor in Astra, even when a fighter is much faster, many reasons for that.
A dual pulse motor not only adds manuevarility, it also adds to whatever velocity you are carrying from the initial solid motor burn. An anti radiation missile will need to catch up to a radar before it scoots.
It will be easier to target stationary arrays, especially if the reports of an IIR in addition to a passive array for EM radiation detection is true. It seems RADAR arrays heat up quite nicely, so even when they stop emmiting, they will still be visible on IR.

@Amrk already pointed out the tech aspect. One more point is, we could have both active as ell as passive RADAR in an AGM. Now whether NGARM would have a active one in it or just IR along with Passive RADAR is to see. But without a sure shot terminal guidance, it is not good enough for moving targets.

One more thing. TAR or FCR do have minimum maneuverability with their RADARS propping up. So the best way out fro them is to shut down the RADAR and deploy ECM.
