Akash Surface-to-air Missile

[harsh]

You have to look at the flight mechanism of both these missiles. Akash does make use of RAMJET engine which means it does consume much more fuel then Aster rocket engine. This in turn means more fuel for more distance means much more weight then Aster30.

This also means more acceleration after ramjet starts.
35 to 40 km version is coming soon as aakash 2.

That means our missile consumes more fuel goes less speed and range that of aster 30 which is almost 30-40% less weight and 50% more speed.....

At 1/10th the cost.

cursory check on wiki:

France has spent €4.1bn at 2010 prices on 10 SAMP/T launchers, 375 Aster 30 missiles and 200 Aster 15 missiles - "Projet de loi de finances pour 2013 : Défense : équipement des forces" (in French). Senate of France. 22 November 2012. Retrieved 2013-11-07.

vs.

The Indian Air Force (IAF) has ordered an additional 750 Akash medium-range surface-to-air missiles (SAMs) from state-run defence behemoth Bharat Electronics Ltd (BEL) at a cost of Rs.42.79 billion ($925 million), it was announced in Bangalore on Tuesday. - IANS, Bangalore | Updated: Feb 02, 2010 16:09 IST - http://www.hindustantimes.com/india...-akash-sams/story-64d5JQejA3LGa5NJGbnVtL.html

You would have gotten 0.75 Euro for 1 USD in 2010.

Periods are comparable.

To get to that cost you have got to use a different tech route. And the choosen tech still gives you 88% Pk for first shot and 98% of a volley of 2.

Mass plays a vital role in its range and speed. Lower mass does mean it could travel lot more then anything with higher mass. Another thing is you have to take into consideration the amount of thrust produced by both the engines in accordance to their weight for speed.

Moreover Aster is a two stage missile unlike Akash, which is single stage, which further enhance its range and speed after launch. And please do note that it could attain a speed of Mach 4 but nowhere it is mentioned that it does sustain that speed throughout its flight time. As for Akash, it do sustain the speed of Mach 2.5 till interception.

Why can't we use astra missile as surface-to-missile? Because it has range of 100km with mach 4 speed.
And why can't we use R-37 missile motor for SAM because it has speed of mach 6 and range of 150-400 km ?

 

[Kunal Biswas]

They are working on NG version, This will be much of a QRSAM than a MRSAM ..

 

[Raj Malhotra]

We are developing the following missiles, which can be used as SAMs:-

Astra-1,2 for range upto 20km (Competing against imported Spyder)

QRSAM for range upto 30km (Competing against imported Spyder, Maitri, Barak-8)

Akash NG for range upto 50km (Competing against imported Barak-8)

AAD for range of 100km (Competing against imported Barak-8, Barak-8 with Booster and S-400)

Un-named SAM for a range of 300km (Competing against imported Barak-8, Barak-8 with Booster and S-400)

 

[Kunal Biswas]

Indegnious systems are not at all competing with any foreign contenders ..

Only foreign contenders are competing with each others ..

 

[HariPrasad-1]

i think instead of implementing the AKASH as our primary SAM in the coming years it is much more feasible to put AAD as primary one cuz it is much more agile,maneuverable,quick and has higher range......it is also in the same weight if not less than the akash....

It is heavier than akash by one and half time.

Astra is an AAM and if you want to convert it to SAM with same performance, then you can't keep its weight to current 150kg. You have to add additional stage with it to provide it with required thrust to attain altitude. Then it would be a multistaged heavier SAM.
For the same obvious reason you cant compare R-73, an AAM with SAM. Engine alone is not responsible to provide required thrust for speed. You have to take care of the whole dynamics and working principle.

 

[G10]

Does this come under fire and forget category.

 

[tejas warrior]

Let the seeker of ASTRA get fully indigennised, you well get hell lot of next generation SAM & AAM coming quickly.

I don't know why people are under-estimating the current Akash. There is hardly anything to change in it for the foreseeable future.

You have a cheap SAM plus
that has a fuller ceiling plus
a fuller slant range plus
the radar that sees very very low at the very far end range of the SAM plus
ability to manage a large number of bogies plus
thrust right till the end plus
great development potential plus
a radar that is effective against LO targets plus
gives you overlapping SAM killing fields.

Imagine shooting a high flying target that can go at only Mach 2, a low flying target that cannot surpass Mach 1 and presenting this challenge every few kilometers, both in ingress route and egress route.

The only thing I would change rather add, is a VHF radar of about 500 km range and that's it.

And may be an optical+IR channel.

See,, we developed this missile 8 years ago and started development 3 decades ago. We do not need this shitty range of 27 KM. By this time, a new faster and more accurate and longer range version should have came in. It has not. I remember the news of 2010 or 11 when it was said that mk2 is coming in next 2 years. It has not came in. Imagine if we would have an Akash faster, more accurate and longer range today, we could have deterred enemies better.

 

[Kunal Biswas]

The requirements are made by People in service not by General mass, Akash SAM like any other program has seen change in its specs in its development time ..

Besides, The requirement for Akash NG is also prepared by IAF which is also of similar range but more advance in terms of electronics ..

I do not know that but when Akash MK2 was conceived, it was with 10 KM longer range, ability to operate on greater profile, faster and more accurate. With the passage of a decade, we can certainly expect the above said additional features.

 

[Kunal Biswas]

“Future improvement of the project is on, and it is being done along with the DRDO . Certain new generation radars and indigenous missile seekers are introduced for Akash system. There are various such improvements, but it is still in the development phase,” he added.

Stating that the range will be marginally higher, Sharma said, “I will not be able to share specific parameters at this stage, but definitely it will be an improved version of the existing (one).”

================

It will be Marginally higher to meet QRSAM requirement ..

Can you please elaborate this?

 

[Kunal Biswas]

Quick reaction SAM are meant to provide cover for mech units, Their range should be no less than 15kms and not more than 50kms, Their are 8-10 regt planned and first 6-8 will be raised with foreign SAMs and later 2-3 with Akash NG sams ..

Why not all with Akash NG?.............
