That info is from Wiki :wink:

btw you forgot to put 00s on your price. It is 300k, 400k and 700k for AIM-120 variants not 3k-7k.

Yes Sir - Unfortunately I'm not that lucky to get more official data, as I'm not working any of these beautiful projects.. But I figured since the article originally mentioned that it is comparable to Aim 120 and MICA, I'd contribute some open source info for the users...I can also ADD mica but haven't had the time to compile that yet..I had also compared Javelin and NAG in the similar manner, along with M1A1 Abrams and ARJUN MBT but never uploaded it as I'm not sure whether the BF user community would want Wiki information..
Btw you are right John, I did chop off the 00's in the K. That would make a big difference for both the users and the producers, yikes :oops:

Again Thanks all for getting this up on BR..
Gagan - Thanks for posting the JPG img..
Rahul for the suggestion and
John - for the correction
Good team work all

Add MICA to your table as next revision. And good job at the comparison.

Rahul M · **Posted:** 02 Nov 2009 06:58 am

good job craig. one suggestion would be that since you are already putting in some hard work, put in some more and convert all data to same units. if you use metre for dimensions for one, use it for the other as well, if range is expressed in km for astra do the same for AMRAAM, not miles (and so on).

one little note : DRDO is not the manufacturer, it is the developer of the astra. I guess DRDL is the lab responsible. production, as and when that happens is likely to be carried out at BDL.

also, why compare nag to javelin, that's apples and oranges, completely different class of missiles.

Found this 2001 mod report (topic 8.30)
It mentions reduction of weight from 16.5 kg to 10.5 kg.

Also this 2009 article mentions

Quote:

The indigenous rocket launcher, developed by DRDO’s Armament Research and Development Establishment is said to be about 50 per cent lighter than the 14 kg Carl Gustav Mark-II launcher presently in service with the Infantry.

The barrel of the weapon has been designed and developed using hybrid-composite technology, used for the first time in the country. The barrel, which is this weapon’s, largest and prime component is made from carbon-epoxy lined with steel. The lighter weapon weight results in reduced fatigue, enhanced mobility and ammunition carrying capacity, thereby improving combat efficiency.

hypersonic reusable missile system sounds good, but i am thinking why waste that much fuel to return back to reload.

the purpose must be entirely different.. may be tech demonstrator for space vehicle, rather.

btw, NASA is returning back to capsule mode to moon and beyond.. surprising indeed since their tiles kept crashing their reusable vehicles. Russians must have a good laugh, a little cold though.

but, it should point to the fact, that how much use we can put this technology ahead!?

Rahul M · **Posted:** 02 Nov 2009 12:45 pm

thanks a lot vipin !!

so this means a clone of the carl gustav with the metal parts replaced by composite ones bringing down weight considerably. sounds like a very good idea !

I think if a cannister carries multiple missiles or warhead (let)....it will just be a drone fling at hypersonic speeds...and also returning drone may return with some information....I am just willing to say that it will do all that a drone can...!!!

with that in mind...it will be good to have the cannister back...!!!

Sounds too iffy to me, may be better to use the kinetic energy to smack something really hard deep in enemy territory instead.

recoverable means different and not necessarily reusable. ... and an ICBM!.. why recover?

its more than iffy.

may return with some information

we can get it from hi-speed networks, dedicated satellites, radars and videos, etc.

Reusable doesn't necessarily mean returnable systems. We in the Rocketry field use the term reusable when we can recover a burnt-out stage and restack or reload it. Maybe 'Reusable' hypersonic missile refers to something whose solid booster stage may be recovered and reused. That's the max limit I can think for a "reusable missile" as anything more will probably make it something similar to a drone.

Saik, considering the Russians built a shuttle clone with tiles when they could least afford it I am sure the Americans already :rotfl:

Especially considering it was never really used for anything productive.

SaiK · **Posted:** 02 Nov 2009 05:49 pm

me thinking, other than the boost phase, the mid-course could be easily returned since, the "G" can start at any re-entry point.. could deliver the mission, rotate around for a while and collect intel, then return if necessary.. but do we need such sophistications?

I don't know how our good fellow Gagan upload the JPEG image, as i've been trying to convert this doc to jpeg, but for somereason, it won't convert and neither would it let me upload.
Hopefully if it's not too much work and if may ask, Gagan could you please delete the current jpeg img and replace it with the one associated in this file. (this one contains corrections highlighted by Rahul and I have added MICA as Ramana suggested.
Hate to be a pain. Thanks all again very much.

Gagan - Did you save the .doc as a pdf and then save it as a jpeg and uploaded the file?

Agni-II test deferred

Quote:

Sources at the integrated test range (ITR) in Chandipur here on Wednesday said the test, to be undertaken by the army with logistic support from the DRDO, has been postponed owing to "some technical snags in the pneumatic system of the missile".

PAD seeker a joint development between DRDO and Russia

Thanks Austin garu. Any idea how much DRDO really picked up from this joint project? The Russians seemed to have not parted with much on ramjet tech. wrt Brahmos.

Brahmos is a joint/co-development with each party bringing in its expertise into the project and commercially too there was sharing involved.

Project AD was a DRDO project to develop BMD system , instead of reinventing the wheel , DRDO just bought the technology of the shelf where ever possible and improvised upon it , so they went for Israel , French,Indian and Russian systems and just developed and tailored it further to our needs. That was the smart thing to do and hence DRDO managed to achieve this feat is less than a decades time.

tejas · **Joined:** 30 Mar 2008 11:17 pm **Posts:** 88

No arguments here. BMD is one area where DRDO really comes out smelling like a rose. I for one don't care how DRDO gets the technology as long as it is truly indigenously available. Acquisition of French and Israeli radars and their indigenous improvement/production for the BMD program being a case in point.

Seeker tech. is closely guarded and is obviously an absolute must for India's tactical missile programs to be truly independent. We must obtain this tech. by any means possible.

Army warms up to Akash missile

Quote:

The IAF’s order last year for two Akash squadrons — dismissed by sceptics as a face-saving burial for the Akash programme — has just been doubled with a fresh IAF order for 16 more launchers that will be stationed in northeast India. And now, Business Standard has accessed even better news for the Akash programme: the Indian Army is considering ordering several Akash squadrons for its ground forces.

AKAASH can easily be integrated in the SAM launcher of naval ships without any modifications.

SaiK · **Posted:** 07 Nov 2009 03:10 am

Akash range can be increased too.. slowly matching up to chasing and killing chinese su30s and paki f16s flying at >50km ceil.. with next gen going scramjet with ++ range. A 80km operational range would be fantastic.

Austin · **Posted:** 07 Nov 2009 03:33 am

This is really good news for Akash , hope this provides the necessary impetus to develop a longer range Akash mk2 and the IAF takes interest in the program.

vavinash · **Joined:** 27 Sep 2008 04:36 pm **Posts:** 450

Where would akash Mk-2 fit in with MR-SAM? But I like the Idea of tank columns being embedded with T-72 based Akash.

vina · **Joined:** 11 May 2005 01:26 am **Posts:** 1137

Hmm. Army comes crawling back to DRDO for Akash SAMS on tank chassis aye ?. It looks like the Natashas have been bitch slapped . What with the Arjun and now Akash and soon Nag to be fielded.

Me thinks that the Kvadrat upgrade has been a dismal failure and the Russian Natashas have nothing comparable to offer and you cant go to the Frech and Isrealis for a tank based system, because they essentially dont have one. So basically the Army shot itself in the foot on that. There is no way they could have procured a western system without watering down specs and based on which they were rejecting the Akash for a long time. And now that the Akash team has come up with the goods, there is no way they could go back to watering down specs!. Nice way to have the nuts caught in the vice aye ?.

I am willing to bet that the Army will come back with more orders for the Arjun as well once the 124 have been integrated and proven.Once an internal constitunecy has been built to support the Arjun , you cant reject it any more on the "logistics" argument and once Arjun starts blowing away the T-90 tin cans in exercises and dissimilar engagements in the training grounds, the Natashas will get bitch slapped there as well..

All in all, nice.

Too late. Done. 2008 article:

IISC develops technology for increasing range of missiles

Indigenous technology to increase range of Indian missiles by a third new

May, 2008:

Quote:

Bangalore: Very soon Indian missiles will fly lighter and longer thanks to an innovative technology developed by the prestigious Indian Institute of Science (IISc) here. Scientists have confirmed that a layer of chromium coating, applied to the nose of a missile, has the potential of increasing its range by atleast a third.

According to reports, scientists at the Department of Aerospace Engineering and Department of Inorganic and Physical Chemistry of the IISc have successfully demonstrated the potential of the coating to increase the range of a missile by atleast 30 per cent without adding fuel.

According to the project's lead scientist, Professor KPJ Reddy, Department of Aerospace Engineering, the chromium coating reduces the aerodynamic drag encountered by a missile or a space vehicle by up to 47 per cent.

''As the chromium coating evaporates with the enormous frictional heat generated during hypersonic flight, it reacts with the oxygen atoms present in the atmosphere and produces chromium oxide,''Reddy said. ''This reaction is exothermic, that is producing more heat, thereby decreasing the density of the air around the nose of the missile. As the pressure reduces, so does the drag force, which in turn enables the missile to increase its range.''

The nose of a missile, conventionally blunted in order to reduce heating, increases the drag. This considerably reduces the range. ''Large amounts of fuel are needed to compensate for the drag and to give the vehicle thrust,'' said Reddy. ''With this technology, we increase the range without using additional fuel.''

The scientist confirmed that the technology would be used not only for application on missiles, but also on space vehicles. He said that a patent application for the technology, which was invented six months ago, had already been accepted.

^^^ Insufficient..

Those chrome coatings work at temperatures created on ballistic missiles upon rentry. There is no specific mention of the technology been introduced or tested on any of our missiles, let alone akash.

But overall positive signs from Army. That is good for DRDO and indigenous industry

SaiK · **Posted:** 07 Nov 2009 01:17 pm

but the chrome? tech should improve on the drag at greater than escape velocity, right?

its only a suggestive technology aspect for lean mean ones in the future. lets hope they get this into production..

Rahul M · **Posted:** 07 Nov 2009 01:20 pm

escape velocity ? :shock:
