Indian Missile Technology Discussion
Re: Indian Missile Technology Discussion
He is being sarcastic.
Re: Indian Missile Technology Discussion
Perhaps Arun garu can clarify this for me but I am at a loss to see the advantage of having a liquid fuel interceptor ( PAD) rather than a solid fuel one (AAD, PAC-3, THAAD, S300, Arrow2). With the Prithvi production line being shut down what gives?
Grasshopper awaits enlightenment from the master BTW Arun garu, I usually read each of your posts three times to make sure I didn't miss anything the first two times.
Your article on Shourya was, as usual, oustanding. I only hope a laser inertial confinement facility can be built to confirm functioning of our TN weapons as outright testing, I fear, will be politically/economically impossible for quite some time.

Re: Indian Missile Technology Discussion
BrahMos II missile has 2013 date.
The GenNext BrahMos II hypersonic missile is likely to be ready by 2013, according to BrahMos Aerospace Private Limited's chief executive and managing director A Shivthanu Pillai.
The Defence Research and Development Organisation's (DRDO) chief controller of research and development was speaking to reporters after his lecture at the Vishwakarma Institute of Technology (VIT) in the city on Tuesday.
Pillai said BrahMos Aerospace has started working on an advanced version of the missile to prepare India for creating a defence system for cruise missiles (DDM ?)
Future wars will be fought with minimum manpower, but with high-powered weapons. "It will be network-centric and fought with intelligent systems," he said.Cyber warfare and robotic systems will dominate the battlefield, he added.

While cruise missiles defense system is largly pivitoed on an effective CM detection system; in terms of CM interceptor, the best type of interceptor propulsion for the purpose is RAM jet, thus a Akash type solid fueled ramjet or BrahMos style liquid fuel ramjet are equally competent.
Re: Indian Missile Technology Discussion
Arun,
wot is the relativity between CM and typical RV`s of a BM in terms of dodging capabilities?
The life of a cruise missile itself is entirely dependent on the level it was being detected/tracked , where as an RV is 180 deg diff to the above equation.

Re: Indian Missile Technology Discussion
RV and CM are not manned crafts with radars to be able to detect an incoming interceptor and start dodging maneuvers. They are unmanned robos that are trying to flying a pre-programmed trajectory.jaladipc wrote:Arun,

The more zig zagged pre-programmed trajectory they try to follow the lesser is the range and accuracy from its INS system, apart from impact on RF signature.
In the case of a subsonic CM, dodging doesn't pay against an interceptor that is 2 times its own speed.
Re: Indian Missile Technology Discussion
I wonder why DRDO is not focussing on building Ramjet propulsion based long range SAM , when its inherent advantage in dealing with Air Breathing type vehical is apparent.Arun_S wrote:the best type of interceptor propulstion for the purpose is RAM jet, thus a Akash type solid fuelled ramjet or BrahMos style liquide fuel ramjet are equally competent.
Instead for next generation of Naval and Airforce SAM we went the Israel route and opted for Barak-8 which has all solid fuel propulsion.
Naval SAM in our context will be mostly dealing with Air breathing type targets on the higher threshold supersonic missile and advanced combat aircraft , for which a ramjet propulsion with its inherent advantage in weight/volume and powered all the way flight would have been of good advantage.
I would have expected DRDO to build upon Akash success and go for a long range variant for a Naval/Airforce variant.
The only reason I can think of why we could have opted for Israel route for Barak-8 is perhaps some good ABM capability that would come with it , but could AAD have served better then on Naval ships ?
Re: Indian Missile Technology Discussion
Austin, Try to find out how much of the Brahmos is being built in India.
Re: Indian Missile Technology Discussion
Austin,
there is a trade off between solid fueled ramjet and all solid rocket propulsion systems.
while the former has a disadvantage in terms of weight and range for the similar sized rocket propulsion system.and cost itself is another issue.
If people are OK with these tradeoffs then ramjets can actually rule the world right from SAM`s, CM`s and AAM`s
U can see why meteor is costing a life hell no less than 1 million Euro while the similar capabilities embedded on simple rocket fueled Astra like system will cost as simple as 160K?

Then how do you consider the CM`s and some BM`s with conformal sensors all over its body to detect an incoming interceptor and dodge in the last millisecond, then again follow its predetermined trajectory/path?Arun_S wrote:RV and CM are not manned crafts with radars to be able to detect an incoming interceptor and start dodging maneuvers.

Re: Indian Missile Technology Discussion
I donno how gud is it to mention the name of the person ,
but a chanakya in DRDO himself mentioned that the later variants of Awill incorporate these conformal array of sensors on all three stages.Taking no chance from an incoming interceptor being a boost/mid/terminal phase interception.Or be it be an laser kill.the system itself will incorporate RWR`s,LWR`s, and IRWR`s and highly robust processor to do everything possible to get the missile into a safe trajectory to hit the same pre-destined location.And he did mentioned that the chanakyas themself are considering high volume missile(means highest possible range)to hit a target which is atmost 3/4 the range the missile can travel giving no chance to mid-phase interception.and the Avariant has already built in boot phase interception deflectors(donno wot he meant )
So considering the tech we are incorporating into a desi mizzile, think abt the enemy himself who already started producing ICBM`sa way back.is our interceptors can consider a smooth way ahead?

does this mean Akash will be also costly compared with Solid rocket SAMs or something specific to Meteor.Austin,

did you even wonder why we feel the warmth of brahmos?
no one is pointing to its price ,while a high level trading is happening between its price and its lethality together with its accuracy.If you want the best system, then you have to put more money on it-----no matter wot.......
Re: Indian Missile Technology Discussion
People are becoming so arrogant while talking about Brahmos-2
Not to mention brahmos-2 will cost our lives.and the deployment of such system in above modest numbers is like taking a grant from unkil.And its range is highly limited in regarding to the liquid H2 onboard.
People has to discount a lot while considering a scramjet based vehicle.fueling is a way risky than the normal liquid fuels(just becos H2 tops the lost of highly inflammables)And that too we have to work on it in cryo stage.enhanced costs.
I some how feel like fielding a hypersonic bomber(unmanned) is far better than fielding a hypersonic cruise missile.At least we can recover the cost in relaunching the bomber again and again.We as yindoos have to give value to each and every paise...isnt it?

Re: Indian Missile Technology Discussion
Merits of RAM jet notwithstanding at the end of the day it is an air breathing missile, hence there are limitations on the max altitude these missiles can operate in; and that is why Arun's emphasis on RAM jet powered SAM's against CM's and UAV/manned aircraft.
Re: Indian Missile Technology Discussion
I am not sure if ramjet will cost any thing more or any thing less than a solid propulsion system.
I think is designing is a challenge when developing such ramject system , but I am not sure of production cost is any thing more than a solid fuel missile.
It is the electronics that goes into the missile that makes it costly.
The whole USP of Akash was a SAM which was to be cost effective and can be mass produced.

Re: Indian Missile Technology Discussion
Both the Shourya/Sagarika and Nuclear deterrent articles IMHO were extrememly well written and informative. I think the take home message must be that if the next GOI does not quickly build ICFs to guarantee reliability of lightweight TNs, the action must be considered nothing short of treason.
We cannot wait 20 yrs. until the the 3rd stage of our nuclear program frees us from the cluthches of the NSG. Moreover, once 4th generation ( fissionless) TNs arrive, I fear Unkil will force us into a FMCT and permanent nuclear inferiority/servitude.
P.S. A tiny nitpick/query. The wt of the TN bum next to its diagram says ~ 270 kg. Just below the diagram the wt is listed as ~340 kg. Which is the correct figure ?

Re: Indian Missile Technology Discussion
The target audience is Indian policymakers, political analysts, strategists, GoI bureaucracy and military. For foreign audience it strives to convey Indian objective, posture and viewpoint.
For the Shourya article the target audience is Indian and foriegn political analysts, strategists and military.

Insightful article. Highly educational to an layman like yours truly. Thank you
Could you do a follow up on the article on these lines, atleast for BR consumption.
1. Minimum no. of nukes required using only proven design under the three risk scenario in the article
2. Minimum no. of nukes required using both proven & high confidence designs
3. Fissile Material stockpile to be maintain to bulk up nuke inventory from one risk scenario to another in the short to medium term assuming that we are maintaining a weapon stockpile for low risk scenario only.
Point 1 & 2, the minimum required taking into consideration the number likely to be destroyed in a first strike.

Re: Indian Missile Technology Discussion
There is still controversy brewing regarding the 2nd Brahmos missile test.
Is it fair to deduce the following?
1) Brahmos did hit the target at 50Km range
2) Army thinks that Brahmos technicians probably cheated (for example entered the exact location of the target, instead of letting the missile software id the target among a clutter of buildings)
3) There seems to be a controversy as to what exactly is the level of intelligence in the system (confusion in target discrimination capability)
4) Army wants a magic solution, and DRDO wants to sell what is already available, with promise of future improvements

Re: Indian Missile Technology Discussion
Indian region may have that number of satellites visible at one point in time, (Moscow time 23:59:10 24/11/2008) as indicated in the picture. This availability will change as the satellites geometry changes with the orbital motion of the satellites. These are not geo stationary communication satellites that will remain fixed in space from an earth based reference frame.Austin wrote:GLONASS Coverage

This partial availability of satellites is only because the glonass constellation is not completely deployed yet.
As the full Glonass constellation is put into orbit, availability over India and other regions of the world will increase, both in satellite count and also over periods of time.
As with GPS, you need at least 4 Glonass Satellites to get a good position fix.
Re: Indian Missile Technology Discussion
Sarang is right!
They have more coverage on the area of threat/interest.
We kind loose out on that

Re: Indian Missile Technology Discussion
Yup. GLONASS shows full coverage for all areas with lesser coverage in Indian Subcontinent, Middle East and South Pacific region. The colors are a little misleading--lighter color means more coverage.
