Yes it can't definitely be reused, but can it not be reverse engineered, or at least studied?
Varthaman's R-73 seeker seemed to have suffered similar damages other missiles had suffered due to the crash, still in one piece.

Chinese already have access to r73, r77 directly bought from Russia for their own su30 copies.

What chinese wanted to copy was pythons tech.

That's what I am asking... if it were instead a Tejas firing a Derby and Pakis retrieved the seeker later on, would China be copying it right now?
Is it possible that those Aim-120 remains are being studied in some DRDO lab as we speak?

They posted in a really long time, but damn! ISRO is already deploying GaN-based TRMs
https://mark20x.blogspot.com/2019/09/chandrayaan-2-gan-based-dfsar-and-more.html
ISRO's Space Application Centre (SAC) has been quite successful in development of GaN-Based synthetic-aperture radars, for example- NISAR dual-band SAR satellite which is being jointly developed by ISRO and NASA is going to feature SAC-developed S-band SAR module. NISAR's S-band SAR module uses GaN-based TRMs developed in India. NASA will provide L-band SAR. Both L and S band modules of NISAR will share a unfurlable reflector of 12 meter diameter.

The answer will definitely surprise you all.

But importantly for the first time lifts veil over one the previously unknown capabilities of one of the most closely guarded projects by DRDO about which very little info exists in the public domain.

Nobody till now had a closest knowledge regarding the presence of control surfaces on the said missile. Infact I am yet to come across a long range SLBM of 3500+ km range possessing control surfaces anywhere else across the world. But feel free to correct me if I am wrong.

In a previous post sometime back I had commented on the said missiles certain distinct and unique capabilities which are not to be seen in other SLBMs of its class and range.

@Chinmoy

Should also answer your queries to me regarding the said system to some extent.

If missile doesn't hit the target and falls on ground the seeker is still likely to be very damaged because the missile is very fast so impact even on ground could destroy delicate electronics.

In some rare case if seeker is intact they will ofcourse study it and try to reverse engineer it.

Regarding aim 120 c5 which su30 jammed. We already have seekers which are equivalent or even better. Technology wise aim class has not muchbti tech us. We are already researching into gan aesa based next gen seekers and eccm.

The answer I am sure, has taken all of you by complete surprise. This completely changed, atleast my own old perception on the said SLBM.

Importantly lifts veil over one of the previously unknown capabilities of one of the most closely guarded projects by DRDO about which very little info exists in the public domain.

Nobody till now had the slightest knowledge regarding the presence of control surfaces on the said missile. Infact I am yet to come across a long range operational SLBM of 3500+ km range possessing control surfaces anywhere else across the world. But feel free to correct me if I am wrong.

In a previous post sometime back I had commented on the distinct and unique capabilities of the concerned SLBM which are not to be seen in other operational SLBMs of its class and range elsewhere around the world.

Now having confirmed the presence of control surfaces aka aerodynamic fins , the next big question is the the location of the fins on the SLBM. Is it in the rear section or midsection or fore section or a combination of the above ?

I think I have an idea but for the time being I won't reveal it , you all can discuss amongst yourselves if you all want to do so.

Note : the concerned control surfaces are made of titanium.

Kindly don't post the pics elsewhere

Control surface on slbm !!

Either this missile is very very precise or it's range is understated.

 

[porky_kicker]

The most sophisticated parts of missile are seeker and propulsion. When you fire a Sam / aam both systems are heavily used and suffer damage.

Not mush use of enemy.

Reverse engineering of a complex system is quite impossible , and the end product is 99% of the time sub optimal than the original product.

We are far ahead in technology than we ourselves credit for. We have a small GaN foundry already set up . DRDO is chief has mentioned fast progress in GaN based air to air seeker and eccm in previous videos.

Nobody interested in this ?

Seriously guys ?

This is a huge deal breaker

No current weapon system in the Indian inventory has the capability to defeat porky deeply buried and hardened WMD sites short of nukes.

Porky SPD uses NATO standardized build plans procured from US to build its WMD underground sites , overground structures are triple reinforced concrete slabs with layers of steel bar mesh , steel slabs and reactive explosives inbetween to defeat overhead strikes , nothing to say of the underground portions which have above same construction with layers of rock and soil above and below it along with massive concrete supporting bulkworks.

This multistage warhead system is our answer to porky deeply buried hardened structures conventionally. The rocket propelled follow on penetrator will be the hallmark if developed successfully. The rocket on the follow on penetrator will fire when the precursor shaped charged blasts through the first few layers of defence and punch through further defences inorder to reach the underground cavern whereby the sensors will activate and detonate the main charge at the rear of the penetrator. Literally icing on the cake.

Follow on penetrator is made of specially hardened materials to resist deformation when punching through layers of rock. A special alloy of tungsten carbide is being trialled .

Note : I know many will say brahmos has the capability to hit deeply buried underground sites. No it doesn't.

Note the warheads on brahmos and you will have your answer if yet undecided.

What you mean by deal breaker? Was there a deal under which we were not supposed to have such tech.?
Can we penetrate Paki underground nuke sites now?

Aerodynamic control for a SLBM would be very unusual, for the booster atleast. It's a tight squeeze in the launch tube anyway. Might make sense for the RV section, but very odd for booster.

I believe we mostly use flexible nozzle, jet vane, and fluid injection tech, since vernier thrusters are mostly liquid fuel motor oriented.

AAD with jet vanes and steering fins

PSLV main motor nozzle with ring of injectors near the outside of the throat.

PSLV side strap-on booster flex nozzle with actuator arm

NASA used the same flex nozzle thrust vectoring on the space shuttle SRBs, developed on peacekeeper/minuteman.

Aerodynamic control surfaces (especially the ones in your pic) on an RV is a regression from reaction control thrusters. Besides, those control surfaces don't even look optimized for hypersonic flight. They are gonna require RV to slow down significantly.
MARVs have around since 1960s and none of them has control surfaces like the ones in the pic.
The only place where those fins could have been used is the first stage. Even in that case, thrust vectoring is a far better alternative. Didn't you notice the trend atw no Agni-X missile after Agni-2 has aerodynamic control surface anywhere on its body?

Being pedantic here, but deliberately slowing down an RV is desirable in some cases, for example, Pershing RV had to have velocity below ~3kmps to allow the mapping radar to work, otherwise plasma around nose cone wouldn't allow rf signals. But that's mostly for tactical and short range BMs.

And how's that connected to my request not to post it in other forums ?

And thanks for reminding me that this is a public forum , I totally missed that fact all these years.

 

[porky_kicker]

DRDO could very well in the immediate future starting recruiting from here.

Definitely will save them a lot of trouble and money on CFD , FEA etc studies and stimulations to figure out if something is feasible in hypersonic regime or whatever etc.

When talented people are available here who can do the same by simply looking at pictures.

Now I can see the reason why older and other members started their own closed groups.

True, there are mainly two reasons to develop a MaRV -

1. You want accuracy, so the RV is gonna make a lot of course corrections post-separation. To do that you want the RV to maneuver around.
2. You want to evade ABM defenses. - More maneuvering

same coin, different faces. Modern slender-conical RV equipped with high-performance heat shield can do both. The difference in the performance of heat shields of older Agni-1/2 and new Agni-5 is noticeable when you see differences in their respective reentry vehicles.

And how's that connected to my request not to post it in other forums ?

And thanks for reminding me that this is a public forum , I totally missed that fact all these years.

Moot argument. Making a request to not to propagate the stuff shared in a public forum is absurd.

Now, this is just plain pathetic. You asked where those fins would go, you got your answer. Not my problem if you don't like it.
PS. If that's the final configuration of those fins, they are fixed control surfaces and definitely not going on the reentry vehicle.
