from the pioneer edit.'Circular Error Probable' of the missile is less than 20 m,
That kind of qualifies this missile for use with conventional munitions.
Not really, with conventional warheads you need to have cep of 5 m or less unless you are talking about MOAB/FOAB/GFOAB.Quote:'Circular Error Probable' of the missile is less than 20 m,

The program proposes converting existing Trident II missiles into conventional weapons, by fitting them with modified Mk4 reentry vehicles equipped with improved a reentry guidance and control systems. This modification is predicted to reduce the CEP (Circular error probable) of the current of a Trident II warhead from 90m to just 10m. No explosive is required since the reentry vehicle's mass and hypersonic impact velocity (13,000 mph) provide sufficient mechanical energy and "effect".
Didnt Putin say that any Russian detection of US ICBM launch would invite automatic nuclear retaliation ? (without waiting to see if the warheads were conventional or not). I thought the program was sent into deep freeze mode after that.Gerard wrote:The Pentagon has proposed "Prompt Global Strike"

Maybe this time the flight parameters were close to nominal and it was a stressing trajectory. So why bother. The other two tests can be user trials na?Arun_S wrote: One question that begs answer is why DRDO changed its position that Agni-III needs 3 more tested before being operational in Dec-2007, TO "no-more test and ready for operational"??
They did not. They compensated for the total error with the Mega tonnage high yield weapons. and that too in th beginning they chose big city counter value targets.ramdas wrote:Of course, Cartosat and IRNSS will help make more accurate maps for targeting purposes. But, I feel it is wrong to say that without these, the maps cannot be made. After all, how did the USSR/China make such maps in the 70's ?
Against cities yes they are meaningful. Against military targets at long distance, questionable.Arunji,
Are you implying that right now, Agni II, Agni III etc are meaningless as they cannot be targeted ?
Accepting complexities in acheving accuracy laid out by you, there are other options besides GPS.Arun_S wrote:BM requires knowing the exact launcher and target position in 3 dimension.
There is zameen Aasmaan Ka differnce between 20m accuracy and 500m accuracy. .............
Use of strategic weapons using unkills GPS as nav tool aboard RV is destined for condom failure when you don't want it to fail. Because unkill gets the launch keys to your use/efficacy of your N weapons/missiles. (the pin to make the condom fail)
And from G. Madhavan Nair via PIB :….. The independent, indigenously developed IRNSS is expected to provide an absolute position accuracy of better than 20 meter over India and the region extending to about 1,500 to 2,000 km around it. ……..
The entire IRNSS system will be under Indian control.
There are two aspects to the accuracy of a counter-force BM. One is knowing accurately the coordinates of the target. The other is the accuracy of the INS itself onboard the BM with error-correcting feed from a positioning system like GPS, GLONASS etc. For the former, we need Cartosat and the latter IRNSS.arun wrote:Accepting complexities in acheving accuracy laid out by you, there are other options besides GPS.

FOR A STRONGER INDIA: Agni programme director and Advanced Systems Laboratory director Avinash Chander (centre), with his colleagues, displays a model of Agni-V at a press meet in Hyderabad on Friday.
Arun Hats off to you and your brilliant work , you saw this much before any one thought this ever existedArun_S wrote:…… And now Dr Tessy Thomas would be the first woman scientist in the country to become Project Director for developing upgraded versions of the 2,000 kilometre range nuclear capable surface to surface Agni-II missile.
Thomas is presently the Associate Project Director of the 3,000 kilometre range Agni-III missile project.
BTW Agni-IIAT was first predicted on BR by your sincerely, purely by the dint of sluthwork and Rocksim. No other analyst has got a wiff of it as yet.
BTW Look at this photo on BR's Agni-IIAT section, Do you see by now the familiar women's face?
Bangalore (PTI) A team from the Indian Institute of Science (IISC) here has developed a innovative technology for increasing the range of Agni type of missiles without additional cost.
The team headed by Prof K P J Reddy from the department of Aerospace Engineering, IISC, achieved the feat by reducing the drag of the missile encountered during its flight, an IISC release said here on Monday.
The drag is the main phenomenon which dictates the range of the missile for a given amount of fuel as the thrust generated by the rocket engine must compensate for the drag encountered by the missile in its path.
Existing techniques for reducing the drag force involve addition of an aerospike at the nose the missile or blowing a supersonic gas jet from the missile nose tip.
Implementation of these techniques involves major modification to the missile structure and hence cannot be applied to existing missiles which are in stockpile.
The new technology developed by Prof Reddy's group involves a radically different technique in the sense that no additional device or power was required for hypersonic flight.
The technique is to coat the nose portion of the missile with a thin layer of material such as chromium. This metal evaporates due to heating of the missile nose during its hypersonic flight and the evaporated metal particles in atomic form react exothermically with oxygen atoms surrounding the body to release additional heat into the air in front of the missile.
I think the IISc should have kept this secret for a while. instead of blurting out Loudly the exact method like coating etc.bala wrote:IISC develops technology for increasing range of missiles

Whats this long range cruise missile?According to Dr Saraswat, India was also developing a ''long endurance,'' long range cruise missile that will fly at high subsonic speeds. Subsonic cruise missiles enable delivery of payloads at low cost and are generally difficult to detect because of their ability to fly at low altitudes.
explicit mention?He also said that depending on existing or emerging threats the need may arise for a 10,000 km range missile in the future. These are generally referred to as the 'Surya' class of missiles and will constitute India's inter-continental ballistic missile capability.
are they planning to use pop out prop fans?According to Dr Saraswat, India was also developing a ''long endurance,'' long range cruise missile that will fly at high subsonic speeds.
