Talk:Agni (missile)

Thanks
Folks, Thanks for up-keeping this Agni missile family page. This page rocks.

As some may recall that I put a fair bulk of the initial content to Agni missiles by making available into public domain the then Agni missile content from www.Bharat-Rakshak.com (latest BR version at http://www.bharat-rakshak.com/MISSILES/Agni.html)

I will later add more content with some more new information.

Thanks & Best Regards

 * Pls note that prior formatting introduced an error. The Agni-II missile speed cant be 7-8km/sec because that will make it an ICBM.


 * Speed of a missile and its range is a strict physical relationship. Please see the paper I published in the latest Indian Defense Review, Indian Long Range Strategic Missiles- Agni-III (PDF). This article has range vs speed relationship in a graph.


 * The earlier quoted reference was mistunderstood. That article mentioned 7-8km/sec speed for the Reenetry vehicle.


 * Best regards

 * Oops I forgot to signoff previou spost with my signature Vishwakarma 21:59, 8 April 2007 (UTC)


 * BTW Rocket Ballistic simulation for Agni-II rocket configuration on this page clearly establish that the Agni-II missile delivers 5Km/sec equivalent velocity for a 1000Kg payload and for 6km/sec for a 500Kg payload.


 * Cheers

Agni II
The Agni II section reads like someone's personal essay. 195.197.240.134 (talk) 13:47, 7 February 2008 (UTC)

Then percived threat by pakistan as Impetus for developement
I feel the blatant deletion of sub-section (Preface: Evolving Indian Security Environment) without discussion on this page is unwarranted and against WP:MOS will be eager to hear comments from Noorkhanuk85. cheers! OlkhichaAppa (talk) 09:42, 19 February 2008 (UTC) Please re-add if otherwise. OlkhichaAppa (talk) —Preceding comment was added at 02:50, 6 March 2008 (UTC)
 * I believe Noorkhanuk85 did not contribute for last 20 days - towards resolution of the dispute. Hence I am removing the neutrality tag.

I think this tag is unwarranted since the article is essentially about Indian missile programme. So I fail to understand how can it represent the worldwide view? OlkhichaAppa (talk) 02:48, 6 March 2008 (UTC)

This article claims that the maneuvering RV of Agni is not merely "advanced," but superior to Western or possibly Soviet RVs. Yet, Indian development of MRV apparently took place in the 80's or possibly early 90's, as per the article itself. The US developed MRVs in the early- to mid-60's, starting with ASSET testing the basic vehicle layout and construction. (See: Heppenheimer, NASA SP-4221, Chapter 1.) Next, The G. L. Martin Co.'s PRIME actually demonstrated extreme crossranges, in a trajectory identical to an actual ICBM launch. Pershing II actually deployed a "smart" warhead, with movable fins actuated autonomously by an onboard seeker head... in 1983. This is all in addition to civilian programs for maneuvering re-entry bodies (i.e. the Apollo capsule, Space Shuttle, CRV), and any Soviet work.

The West then abandoned MRVs. Highly-accurate rocket motors, combined with worldwide intelligence in the form of high-accuracy geodesy and frequently-updated atmospheric models, negated the need for terminal correction. Meanwhile, ballistic missile defenses were countered by the deployment of large, reliable ICBM forces. Combined with a reasonable number and sophistication in decoys, maneuvering RVs became costly, weighty, and unnecessary. For the highest precision, the West turned to cruise missiles, with CEPs of a few yards.

And yet, this article claims MRVs are an Indian invention, not an Indian attempt to catch up to the West. It is this article that is the invention. —Preceding unsigned comment added by 128.8.238.186 (talk) 19:38, 23 March 2008 (UTC)
 * I agree. A lot of the content has been blatantly ripped off Bharat-Rakshak.com, a clearly non neutral source. I doubt the Indian government would claim to have invented reentry vehicles. Also the Indian government has never disclosed the exact details of the reentry vehicle except for admitting that a reentry vehicle has been developed. The rest is pure speculation and hyperbole. Information about the reentry vehicles does not exist in the public domain. The information that is not from official news sources in this article and the information without references must be removed.Andy anno (talk) 03:20, 15 May 2008 (UTC)
 * I have changed the content of the agni RV Mk2 to reflect the fact that the agni RV is better than only the first generation RV's developed by the US and the soviets and that it is more a single maneuverable payload as opposed to the first generation Indian as well as western(note that the P5 developed the first generation of missiles soon after WWII) which were just passive payloads on top of rockets.Andy anno (talk) 05:40, 15 May 2008 (UTC)

Range
Why is it that the range in the infobox and article of the missiles don't match? For example the infobox shows the range of Agni II as 3300-4800 km (ICBM class) while it is stated in the first part of the article as 2500 km (MRBM class)? Something's wrong here, and can somebody with knowledge on the subject please clarify? Thanks S3000  ☎  10:30, 27 March 2008 (UTC)
 * The standard range of agni II with a 1 ton warhead is reported to be 2500km. Also Agni V will not be designed to be of the ICBM class unless a lower capacity warhead is used since the drdo is targeting a range of 5000km officially not 6000km as it was stated in the article earlier inspite of the references showing it at 5000km. Andy anno (talk) 02:49, 15 May 2008 (UTC)

Agni-V ?
Well I've been looking at all the ref for the Agni-V, but when I look at it I see nothing stating that the Agni-IV is being called the Agni-V or anything about them skipping Agni-IV. In fact, ref 28 (the apparent closest to date ref article), still says there is an Agni-IV instead and not an Agni-V. Even ref 24 which is suppose to say that Agni-V was Agni-IV doesn't have a single thing about this. I'm no expert on this stuff, but when I read all the refs, it seems like they are developing 2 separate missiles that have equal range for some odd reason. Could someone clear this up, or at least add refs that clearly states that they are in fact the same missile. Spitfire8520 (talk) 10:08, 30 June 2008 (UTC)

Yes, the Agni-IV is skipped. There was a statement from DRDO regarding this. And that report stated that the next missile is going to be the Agni-V. The Agni-V (Earlier Agni-III plus, Agni-IV) was said to be in the range of 5000 km or 6000 km. We can assume that it is a single missile and its range may not be 5000km as stated but 6000km. For political reasoning the range will always be 5000km. Regarding another missile that they are supposedly developing to be tested this year end/2009 starting may be a version of Agni-III with longer range (may be a lower payload). After Agni-V based on threat perceptions a missile will be developed and that is said to have a range of 10,000 km. This may be the Surya (Anyway missiles with ranges of 6000-10000 km is not required because it is ocean b/w the U.S and India. Surya will be eventually developed just to make sure that there is no discrimination against India in any negotiations and India is not sidelined for not having ICBM.Chanakyathegreat (talk) 13:05, 3 September 2008 (UTC)

Separate articles
Separate articles need to be created for each and every Agni and from the presented article links can be provided to those Agni pages. There are so many Agni's and it's difficult to handle all in one page.

Distance
Hey, should there be a map showing the distance of each agni missile, a map like this picture here?Deavenger (talk) 02:25, 5 March 2009 (UTC)


 * There should. I had created the above image in order that it could be used on this page - in case of Agni-I, it may be difficult, due to the small range. However, I dont see why it should be a problem for the Agni-II and Agni-V... I'll try and create a similar image for these missiles if I can.


 * If anyone else would like to take the baton, I used Google earth to get an approximate distance, created circles of that size on paint, and put it over the blank map image, afterwards painstakingly erasing the unneccessary part of the circle by taking parts of the map and placing it over the area. Took me an hour and a half to make the whole image.  Sniperz 11 @CS 07:58, 5 March 2009 (UTC)


 * P.S.... given that Agni II is 2500 km, and agni-V is 5000 km, we can use this image on the respective pages since the circles are 3000,3500 and 4000 km, which is pretty close to the required ranges.  Sniperz 11 @CS 08:00, 5 March 2009 (UTC)

China?
Why does this article state distances from Chinese cities? Relations between China and India are presently friendly and I don't believe this article should reflect otherwise. GSMR (talk) 20:48, 20 July 2009 (UTC)

Velocity of Agni Missiles?
Hi, congrats and many thanks for presenting this information and of course the references. It has been great reading about India's Missile capability and going by the performance data and specifications, it seems that Agni and Prithvi are far better and more important than our BrahMos. Anyway, there seems to be some problem with the velocity specification (the current page shows a 5-6 km/s). Is this right? I know for a fact that Agni does not do hypersonic yet and a speed of 5 km/s translates into about Mach 15!!

Pcsrao (talk) 06:18, 5 March 2010 (UTC) yes you are right, i have updated it. with citation. you can have a look. -- D ℬig XЯay  01:25, 20 October 2011 (UTC)

C.E.P.
"most accurate strategic ballistic missiles of its range class in the world" Based on the statement that these missiles get their terminal guidance from GPS. Wouldn't the US and ICBM capable NATO allies have the same capability? —Preceding unsigned comment added by 67.176.151.116 (talk) 06:38, 9 October 2010 (UTC)

pictures?
hey could you put a picture of the Agni III missile on here there's plenty of them online and there have been many news reports showing the actual missile it self — Preceding unsigned comment added by Buklaodord (talk • contribs) 05:38, 3 January 2011 (UTC)

Added sections to the article and various citations
Added verious sections to the article and various citations from news papers to support the text and uncited figures. also replaced a dead yahoo news citationa with a same working Deccan herald news site .-- D ℬig XЯay  00:18, 20 October 2011 (UTC)
