Now believe what u want to....drdo plans to confuse enemy to death untill horny chacha leaks the actual range

Qrsam burns it's motor till end game , it's radar and command control is optimised to have higher sskp than range and operating quickly while on the move. Vlsrsam is being designed for vertical launch operation for large area defence ,plus range of vlsrsam is more than qrsam even though it's lighter owing to the fact that it don't have to be extremely maneuverable for the role of general purpose ad missile

TBH, I still don't find the logic behind the so called differences.

QRSAM has a bigger warhead so it must be more lethal than VL-SRSAM but VL-SRSAM has a directional warhead so ultimately the end resuls become same.

And how're you going to optimize radar when two missiles have the exact same radar!? Yup, QRSAM uses the same 178mm Ku-band radar of Astra and VL-SRSAM. This is the sole reason why they had to taper down QRSAM's 225mm diameter body to fit that 178mm seeker.

Earlier I used to think that Akash-NG and QRSAM are redundant. But as some members pointed out about its range, QRSAM and VLSRSAM became redundant. And now after this 80km range of Akash-NG, the MRSAMs became redundant.

Qrsam is launched at angle for faster response, i don't have details on vlsrsam radar ,then I can comment properly but both have definitely some difference

Isn't the vlsrsam for the navy and qrsam for the army ? And vlsrsam has tvc vanes and the sr Sam does not ?

 

[Lonewolf]

Isn't the vlsrsam for the navy and qrsam for the army ?

Vlsrsam for Air force is also being developed

 

[patriots]

Let me jump in


1. Akash with 25-30 km range ,is for airforce bases , other statistical important places , mostly in stationary condition, means missile will be placed there like pechora ....

2.aakash prime or akash s with 3okm+ range rumour, will have better capability due to an aesa seeker , but role remain s same , also there was news that akash prime will be good in mountainous region. Also 360 protection
3.qrsam is for army , basically to protect the moving infantry or armour s , range almost same as akash but akash is a heavy missile ,can cover higher altitude,but qrsam can fire in move .
4. Vlsrsam ,it's for navy , it's a vertical lunched missile , it will replace Barak 1 .range 15 km

5. Mrsam / lrsam ....mrsam called in iaf and ia as they will get higher range missile s , iaf already got s400
Lrsam called in navy ...
6.mpdms - it is for man portable operation , also vehicle mounted ones .range 6 km
So all missile s are different , they have different characteristics , different roles

Muse on this if you want, FCR range almost 3 time the missile range given by bel poster lol

Actually the range of the missile is a lie
No one tell you the actual Range it's +_ x% of the range that we get in brochures

 

[Lonewolf]

Why mostly production partner understate the range ??

 

[porky_kicker]

Why mostly production partner understate the range ??

No idea

Afaik production agencies get info on a need to know basis , afaik infact they are mostly clueless most of the time , if you see interviews of some drdo officials they are mostly clueless on specs, especially of systems of which they are not associated with

Afaik those working in def sector operate in need to know basis or will raise suspicion , True in any critical sector where secrecy is Important -> compartmentalization

And possibly misinformation fed to them , bec as production agencies it's not their business to know op parameters unless it's deemed so

Yes, especially true incase of AAMs
Imo though for what its worth for SAMs one can arrive at a loose estimate

1. Akash is for both IA & IAF, IN QRSAM project failed.
2. Akash prime or akash s is further improvement of Akash maily with seeker & improved electronics & c&c.
Who told you akash having aesa seeker ?
3. QRSAM for army, becz akash don't meet 3sec reaction time req.
4. VLSAM range greater than 20km, maybe upto 40km, it is similar to essm with lesser range.
5. Barak 8 with different names, range 70km. speed mach2.
QWho told you akash having aesa seeker ?

 

[johnj]

Muse on this if you want, FCR range almost 3 time the missile range given by bel poster lol

FCR range always greater than max missile range.
2m2 is only good for targeting fighter jets. helios.
FYI- akash max range 30km, its fcr range greater than 60km
Maybe BEL confused with akash s with ng or a new version with rocket motor.
May be new FCR comes with 150km range for 1m2[not sure]

Surveillance radar range is generally 3 times or so missile range, maybe more

As for FCR, afaik generally range more or less proportional to max missile range, though always on the greater side like margin of upto 50% more,

Here literally 3 times more

As for Akash radar, from brochure range is given as 2- 80 km for 2m2 rcs
It is a multifunction radar so above range is for tracking or surveillance/search ?

Anyways let's see

Rf seeker

Yup, it was always bound to be a dual pulse motor. This is the only reason they ditched ramjet in this variant.
I just used "etc" in place of Akash-NG

We have mastered this dual pulse motor technology, it'll keep sowing in more and more designs

what is PSD??

 

[Lonewarrior]

what is PSD??

Pulse Separation Device.
This black thingy in between two different types of grains -

It is the only technological advancement that makes a single pulse rocket a dual (or multiple if you keep staking multiple PSDs) pulse rocket. It must be strong enough to prevent the I grain from igniting II grain but at the same time it must be fragile enough to not disrupt the burn of II grain.
