DRDO QRSAM and SPYDER Air Defence Systems

Could you explain the organization of air defence brigades,squadrons,regiments and batteries?

Barak battery = 4 launchers (with 8 missiles each), 1 CP, 1 multi-fuction GaN radar.
IAF: 2 batteries make a squadron.
IA: 8 batteries make a regiment.

SPYDER-SR battery = 6 launchers (with 4 missiles each), 1 CP, 1 multi-fuction GaAs radar.
IAF: 2 batteries make a squadron.

Akash battery = 4 launchers (with 3 missiles each), 1 CP, 1 BSR (MS), 1 FCR (PESA).
IAF: 2 batteries make a squadron.
IA: 6 batteries make a regiment. Regiment has regiment level surveillance radar and CP.

QRSAM battery = 16 launchers (with 6 missiles each), 5 CP, 1 BSR, 4 FCR. All GaN radars.
Each battery has 4 firing units. Each unit = 4 launchers, 1 CP, 1 FCR.
IA: 3 batteries make a regiment. 1 regiment has a regiment level surveillance radar and a CP.
IAF: None as of now.

NASAMS II battery = 12 launchers (with 6 missiles each), 4 CP, 8 multi-fuction GaAs radars.
Each battery has 4 firing units. Each unit = 3 launchers, 1 CP, 2 radars.
Dunno how many batteries IAF plans to buy.
Not designed for use by IA.

S-400 battery (Russian composition) = 4-6 launchers (with 4 LR missiles or 16 MR missiles or a combination), 1 CP, 1 BSR (optional), 1 FCR.
1 battalion = 2 batteries. Has a battalion level surveillance radar and CP.
1 regiment = 2 battalions.
IAF will obviously not follow this system. You can say 1 battalion = 1 squadron. So IAF will have a total of 10 squadrons.

Excellent clarity.
We know that 8 akash squadrons serve with IAF with 7 more stalled in acquisition process.Army has 2 regiments and doesnt want more..focusing on qrsam.

How many mrsam are iaf and ia procuring?

Qrsam is 8 regiments requirement for army.
Spyder was reported to be 18 squadrons bought for the air force ,1500 missiles of MR version.But pics so far are of 4 missile carrying SR version,and an airforce oficial said 3 squadrons are inducted..4rth ongoing.Whats going on?

The army ordered 2 regiments of Akash-1. But this missile couldn't meet the requirements of SRSAM. SRSAM is a separate requirement independent from QRSAM, it is meant to protect static targets within enemy territory. IA wants 4 regiments, and these were supposed to be fulfilled by SPYDER SR. But DRDO came out with Akash-1S, with a seeker, so now this seeker based Akash will fulfill the remaining 4 regiments. IA will soon be placing an order for 2 regiments of Akash-1S. It's also possible SPYDER SR will be inducted for 2 regiments instead of giving all 4 to Akash.

18 batteries for the IAF and 40 batteries for the IA.

Qrsam is 8 regiments requirement for army.

It was supposed to be 3 regiments of SPYDER SR and 5 regiments of QRSAM, but now it looks like everything's gonna be QRSAM. I believe IA is still pushing for simultaneous deliveries for quicker induction, but I think that won't go anywhere due to the superiority of the QRSAM over SPYDER SR.

I think it's the SPYDER SR, not MR. At first I thought we chose the SR launcher mated to the EL/M 2084, which qualified it to be MR equivalent, but I am now seeing pics of the EL/M 2106, which is designed for the SR and not MR.

You can see TATA and Tata's logo on the truck, making this the Indian version.

The radar is EL/M 2106. So it looks like the IAF's SPYDER is the SR and not MR.

An addition to post 44. I mentioned SPYDER SR has a separate CP and multi-function radar. But on the Indian version, the CP and radar are on a single truck, as you can see in the image above. This is an India-specific design. Not sure if it's a safe design choice though, considering the radar is the primary target of the enemy. A successful hit will kill the personnel in the CP as well.
 
  • Informative
Reactions: Austerlitz
He got it wrong on multiple counts here.
  • Astra-VL is for the navy requirement of 11 systems.
  • Astra VL is not equal to QRSAM. Different requirement. Different designs although they share parts.
  • How is it going to EO sensors again ? :rolleyes:
 
To be fair H. K. Rout is a very reliable source. But sure mistakes do happen.
Once he reported Barak 8 failed looking at its trajectory. But it was going for a low flying kill.

Also, QRSAM is Tank buster apparently. :LOL:
