DRDO's design should at least be based on basic physics. If you do a Google search, you will know that the air resistance in the supersonic stage is mainly Wave Drag, and DRDO's design greatly increases Wave Drag.

This is the second mistake. The main reason for the lift generated by this type of American missile is the Double-Cone design. The four wings are only used to control the direction. The DRDO missile generates lift by adding four huge wings.
If the US LRHW and this Indian missile can be considered HGV then all these missiles with Double-Cone design can be considered HGV
DF-16
DF15B
Like I said, it is not the same missile as the Indian one. They generate lift differently and have different drag. The LRHW relies on the body to generate lift, while the DRDO missile uses wings. The Indian one has much greater drag.
I am convinced our laal gamchha dhari friend from Han Pradesh will keep shifting his goalposts. Now he’s comparing MaRVs to HGVs, throwing around physics jargon. Yet ironically, he seems to miss the fundamental principles of missile physics and trajectory dynamics that set HGVs apart.
It’s like that scene from the movie where Supreme Leader Aladeen insists, “The missile must be pointy!”. And the other guy's words couldn't convince him because Aladeen's own flawed conviction.
hybrid flight vehicle like sagarika are called boost-cruise type , slightly different to regular HBGV flight vehicle but also falls under same category.
The difference is while in flight, this can maintain same altitude in flight while never having to leave the atmosphere. this means compared to a heavy and larger ICBM/IRBM/SICBM delivering payload in a depressed trajectory , the Sagarika RCS will be way smaller as well as not lose altitude gradually. This way it mimics a cruise flight. Sagarika also can enter in a glide trajectory and it can do the skip and hop to go much further. Major caveat being while the 800km and 1900km ranges were based on payload weight, actual missile will be able to cover same range bracket with same warhead by trajectory shaping as per mission requirement. The nook delivery mechanism has provision for likely 2 warhead config, one in a tactical role, the other is to take out whole base like Kirana Hills..

What excuse are you going to use for the upcoming Dhvani and LRHASM now? Dhvani, which has a similar shape as DF17 but somehow I expect you to use your wing physics there as well
In Han world the incoming projectile is fake, it's always a day of rest for air defence systems. If only the Chinese children working in dildo factories got a similar level of rest, maybe they can go to school and eventually make China achieve decent AD systems.

If that's what you're talking about, if this can be achieved in India, then it is definitely an HGV, but it only exists on the drawing board now.
Are you the same Chinese guy who laughed at our aircraft carrier design saying that it does not have bibulous bulge (in this forum? Or was it another person?
Oh here comes the concern trolling "Can India do it?". Good luck underestimating Indian missiles. I hope your generals also have similar thought process like you, it will make things a bit easier for us.
Depends on flight profile on the re-entry vehicle of these chinese missiles.
Conical hgvs/ pseudo-hgv like US LRHW, BM-O4, have a flight profile more similar to a hgv than to a traditional Marv, modern conical re-entry vehicles can be made to fly similar to an hgv you don't need a design with flat bottom like envisioned in traditional HGV's, though they still don't generate as much lift/ can't glide as far as traditional hgv( though modifications like fins can be added to somewhat deal with that) but do offer lot more volume in similar length article.
So ultimately depends on what is prioritised, range, volume etc what requirement is, if you can achieve "desired range" with a concial design with less lift( they will still generate lots of lift and even shock waves to ride on,because of their speed ) then the extra volume is benificial.
You have very rigid understanding of systems and their performance, the the lines between categories are lot more blurred.
You can make a rocket powered hypersonic cruise missile, Don't neccesarly need scramjet for it, though rocket motor is a lot less efficient method of propulsion compared to scramjet, but still possible, with "allegedly" some real life examples in service.
K-15 and Shaurya have lift generating fixed trapezoidal fins. It has a much higher lift to drag ratio than the RV of DF15B and DF16.
And if consider these RV as HGV, then this is also a HGV.

So there is an idea that the dia is not 2m in that pic, but greater than that possibly. Lets see.

Vro our chinese friend does not yet know how and why a high beta double conical rv with blunt leading edge nose tip is useful in terms of its flow field and flight characteristics. Read below
One of the big reason why even Agni 1, a mere 700km ballistic missile if used today in any battlefield would give absolute nightmare time to any existing western or eastern modern AD system. They will be able to track it, but will not be able to engage it successfully 9 out of 10 times. And it does not feature the control surface we see in the much longer range cousin. Further future variant as control law & guidance algo improved moved onto conical shell structure for greater speed & acceleration.

Vast majority of Chinese ballistic missiles also don't even come close to the accuracy of Prithvi or Agni from 1980s!!! Admittedly, we used western electronics for the guidance system during those times, but even then, achieving a CEP of 10-50 m is no mean feat, something their missiles even now don't do.
@_Anonymous_ we were speaking about racism in the West the actual racism is in Han land where they think they are inherently superior than everyone else. "India is racially inferior so of course it will never achieve HGV and the missiles it has now are inferior and crude" - the thought process of our resident Han
. If China has this attitude then it doesn't bode well for them, US always overestimate it's enemies which is why they're good at fighting conventional wars.

Our chinese wuamo have gone to the extent to claim, pralay is just cheap ballastic missiles lol,
Now straight up compared LRHW with DF-15B, yeah the US Navy & army spend millions of dollars to just to develop advance Marv, which they already possess for decades
The problem with the Han is they're deeply insecure about us & absolutely paranoid. They seek to validate us at every turn because of the aforementioned factors & are puzzled we don't seek their validation, getting abusive when we ignore them.@_Anonymous_ we were speaking about racism in the West the actual racism is in Han land where they think they are inherently superior than everyone else.

I've tried telling Wumaos for some reason the west has held great fascination for Indians & has captured their imagination like no other place on earth.
When Indians haven't moved en masse to a Japan or a Singapore or a Hong Kong when it is was under British rule , what makes the Han think we give a damn to whatever milestones they cross technologically speaking or however advanced China becomes as a nation ?
We just do back of the envelope calculations & in practically all such cases it turns out we can match them in 5-10 years & in some cases 15 years . That's the extent of their advancement over us.
This answer triggers them like no other for in their minds India = Paxtan = Vietnam = backward aka need Han handholding without which we can't accomplish anything .
You don't have discussions in good faith with a Han or an *censored*. Just kick his a r s e & move along. Don't waste your time. I'd have done so myself , in my own fashion but the administration here wants a "fair " deal for everyone who's an agenda to phuck us which is the reason we don't get along.
"The hypersonic glide missile is in a much more advanced stage. We have done one development trial, and we expect that in the next two to three years, we will complete all the development trials, and then it will be inducted," the DRDO chief said.
"In hypersonic cruise missiles, we have recently proven scramjet propulsion for more than 1000 seconds, which is a major breakthrough. We hope the government will sanction a program to convert this scramjet propulsion into a hypersonic cruise missile weapon system. I estimate that it will take about five to seven years before it can be inducted," he added.
