Indian Missile News And Discussion - Arun_S - 03-23-2010 Pk of interception is higher when missile is approaching re-entry. The azimuthal accuracy from Radars is weaker compared to range accuracy. And launch a ABM that later requires wide correction makes it infeasible. So once radar sensor fusion is able to arrive at a solution that predicts missile in time space such that it fits into the relatively small kill box envelop (as determined at the moment when ABM is launched), then one can launch the interceptor. Hopefully with above one can see that mid course interception may not be most effective. Unless there is a grid of radars on the way with high accuracy and the trajectory can be more accurately determined before the missile reaches Apogee. As Indian sensors improve and grid becomes denser, mid-course interception will be closer to reality. Indian Missile News And Discussion - ramana - 03-24-2010 The book "Lightning Bolts" has a section on the merits of reaction jets manuvering vs flaps and says that the former is more challenging. Further flaps are simpler and adequate in the lower atmosphere. Agni RV uses reaction jets. Indian Missile News And Discussion - sai_k - 03-24-2010 good read http://issuu.com/a4press/docs/arms-2010-1 Indian Missile News And Discussion - ramana - 03-24-2010 Awesome find SaiK! Very descriptive. Indian Missile News And Discussion - Guest - 03-25-2010 Arun_S and ankit-s, This is the graphic of the Bulava missile. 1. Notice how the MIRV bus orients the RV in the correct direction for re-entry, well into the ascent phase itself. 2. The RV nose tip points downwards when in storage in the missile as shown in the graphic! Arun_S, could you explain the process in detail and do a similar animation for the Agni series and include deployment of RVs and decoys.

At least the article is factual.

Indian Missile News And Discussion - vasu_ray - 03-25-2010 while land launched Ashwin protects key cities and installations, aircraft mounted ones having longer ranges can increase the size of the protection bubble and also be redeployed quickly Another observation is, there seems to be lot of similarities between reaction jets on Agni RV with the ones seen on space based interceptors, anyways, if long range radars are an issue for accurate mid course interception, isn't that an issue for ASAT weapons as well? unrelated to the above, similar to wind tunnels simulating mach nos, can the atmospheric reentry conditions be used to simulate the blast wave of a nuclear explosion with reentry speed modulating Kt (albeit with no radioactivity)? Indian Missile News And Discussion - sai_k - 03-25-2010 An aam question: On the MIRV, Let us assume we have multiple targets that are really spread apart - one perhaps near our border and the farthest one as far as one of the RVs can reach. What would be the min and max ranges we could cover with the configuration in our best interest of thoughts? If I say for A3/4 (6000km range,1.5T load, 6 MIRVs) can I hit one of the target at as close as 800-1000kms, while the rest may be at various distances? Thanks Indian Missile News And Discussion - sanforkom - 03-25-2010 hi everyone..this is my first post on this forum.i really admire works of shri arun vishwakarma( arun s ) in the field of missiles.........ive learned a lot from your posts........... sir i have a question though it may seem quite naive.........though we have icbm capability , do we really have a true icbm......does surya really exists........

[/quote] Thats a graphic depicted by a journalist/reporter.Dont take it as granted as official release. Not even in my worst nightmare,no country will put out its launch sequence and seperation of warheads. Even if DRDO folks say, that A-3 1st stage gets seperated here and then blah blah..... its only a media wash,but not the actuals. How it works is,folks working on the same missile (different components and sub systems) will have no idea about the actual specifications...unless the project lead speaks out. Stage integration experts work on the related designs to seperate that particular stage at a particular instant(say after 2 min of burn time or altitude,......) the whole key rests with the final integration design team that writes codes to control all stage releases and trajectory corrections,..... It is only them who knows the optimal values and actual schematics. Rest assured, the less the public knows about these actuals,the much better the nation can keep the adversary at a guestimate work(high level of uncertainity).

[/quote] Nothing is naive.Infact every thing is apparantly naive to everyone cause the knowledge is an ocean and cant be swim across by any single person. Regarding your question: What is in your mind,when talking about true ICBM capability? It is just the definition varies for different nations according to their self geographies and doctrines. India does have an ICBM in its arsenal(to be inducted)in the name of A-III.However,not being a purpose designed but a modified,the ranges are simulation based. Having said that,India is readying an ICBM relevant to its doctrine in the name of A-V. But,if u have a R-36/Topol-M or something something else in your mind--they might see the light only after the end of this decade.

Thanks [/quote] No way to figure that out unless on has the deep inside track. The number depends on max fuel carried by the RV. For pure ballistic RV that spread can be few tens of miles. For hypersonic maneuvering RV it is a different story and depends on full range ballistic range of missile and the maneuvering RV design. For Agni-III+ class missile carrying 3 petals of Agni-II type (not exactly the same RV but similar) that relative RV dispersion can be many hundred miles (> 1000 km possible).

[/quote] Your name and post sounds like SBM, are you SBM? Indian Missile News And Discussion - sanforkom - 03-26-2010 Arun S SBM ........... no sir i am not ( if its someone u know )...........otherwise i didn't understand what it means ( SBM ).........kindly explain...... Indian Missile News And Discussion - sanforkom - 03-26-2010 Chandragupta , Arun S What i meant by true icbm was like topol m , Satan or peacemaker types............not A3 or future A5..........i wanted to know about surya if it really exists.........ive read somewhere that we have changed name of surya 1 to agni 5 to limit the eyebrows raised....and regarding our nuclear doctrine of minimal credible deterrence and no first use policy........i dont think that it doesn't allow us to go for true icbms.........or does it Indian Missile News And Discussion - sai_k - 03-26-2010 Arun_S, thanks for the answers. Is it plausible to think of having couple of petals falling off the second stage for covering nearer distances on the same flower mission? Indian Missile News And Discussion - Arun_S - 03-26-2010 [size="2"]sai_k: No. [/size] [size="2"]Dr sanjay: ICBM is one that can go to another continent and then there are others that can go to all continents. And it depends on where in the continent it is launched to reach the other continent. Then there is the other question if that vehicle can carry only a rose flower to that distance or carry a usable 100 kg conventional explosive or a 2000 kg strategic payload. IMVHO it is a moot point to compare Indian missile that carry rose flower, or stones to long range with those that carry light weight, high yield TN warhead to long range. Apple to orange comparison !
