The thing under blue tarpolinis swift and u can briefly see tapas at .18

Red arrow: Tapas
Blue arrow: Swift (undercover)

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

This needs to be made as a mini-sticky post for reference.

Rf seeker

What ??
The Question is - Who told you akash having aesa seeker ?
OR Who told you akash having aesa active radio frequency seeker ?
OR Who told you akash having active electronically scanned array active radio frequency seeker ?
active electronically scanned array active radio frequency seeker= aesa active rf seeker.

 

[johnj]

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

BEL confused with Akash s/prime with ng.

Is that an AESA seeker!?

 

[Roland55]

Is that an AESA seeker!?

This is it.

BTW, where IR version

 

[Lonewarrior]

This is it.

BTW, where IR version

Yup, that's why I asked, that's not an AESA. You never (except Captor E) mount an AESA on a gimbal.

As for IR one, it'll take some time. We have already developed an IIR seeker for our MANPADs it's just a matter of months before we scale it up for AAM.

 

[jai jaganath]

AFAIK it has been tested why not inducted if not 1000s atleast 100s

 

[flanker99]

This could affect iaf awacs availability in future.

Why not? Makes sense to do so atleast in missiles where it needs to course correct at extreme angles.

A320ceo family aircraft formerly belonging to Air India being used for FTB, AWACS and SIGINT are different from the a320neo of Indigo and Go First. The Air India aircraft use CFM-56 Engines which face no spare parts issues, unlike the Pratt and Whitney engines used on the Indigo and Go First ones, which are newer and facing supply chain issues. Even the A320neo of Air India and Vistara using CFM LEAP-1 Engines are not facing such issues.
CEO=Current Engine Option
NEO=New Engine Option

I think it would too, especially since these missiles will have to take an indirect path to the target.

Because of two reasons
1. AESA radars arrays are extremely heavy compared to a simple slotted antenna so you now need more powerful servos for gimbal in already constrained SWaP availability.

2. BVR-AAM missiles are usually fired from quite a good stand-off distance if not beyond visual range, so this requirement of extreme radar angle doesn't matter much. This extreme radar angle only plays useful role in close range heat seeking missiles where you would fire it in high off-boresight.

The typical cone of 90° offered by both mechanically steered radar and AESA is more than adequate for long ranged AAMs.

I too, am curious about that. Hardware weight and complexity notwithstanding, it would be a no-brainer.

Nope. I agree for the point about BVR missiles, but this was about SAMs. They do need to often take an indirect path to target, and will really benefit from gimbal.
