India does not have an ICBM programme

[Justin Joseph]

I dont need any education from kinetic, he seems know less than me about rockets bcoz he said that Rocket can change to ICBM just get a bit sofeware modifying. I am reading wiki, but in wiki artcle, there are so many defference between ICBM and rockets.

Wiki master, if ur knowledge is limited to the searching in wiki then i got the answer why ur post always lacks info and full of trolls.

I think we should wait a man who know well about space tech and missile tech to answer me. Maybe "faithfulguy" can answer it, it seems he knows lots about ICBM.[/I]

you can trust my opinion, I did aerospace engg for 2 years before I dropped to pursue engg in IT.

Also I am involved in various researches related to Astrophysics, Aerospace and Computers.

Let me explain clearly. A rocket can be converted into an ICBM. There is no difficulty in it. In fact all the missiles you see are nothing but a warhead attached to a single or multi staged propulsion system. The only difference lies in their course and re-entry mechanism.

Also re-entry is same for all types of ballistic missiles. So if Agni III was successful, the same re-entry mechanism would work on an ICBM too.

The tech you pasted

"After launching a ICBM may release several independent warheads, and penetration aids such as metallic-coated balloons, aluminum chaff, and full-scale warhead decoys. And I aslo suggest you read some article about ICBM. Launching ICBM is a very easy phase, but make the ICBM hit the target authenticitily is far difficult than just launching a rockets."

independent warheads = MIRV
penetration aids such as metallic-coated balloons, aluminum chaff, and full-scale warhead decoys = used to reduce rcs, provide countermeasure to aerial missiles

None of the ballistic missiles are 100% accurate, they all have 0 propulsion when they enter the atmosphere. Their direction can change while re-entry depending upon various factors. This is because ballistic missiles unlike cruise missiles are catapulted using their boosted stages, once the missile gains momentum, the engines are switched off and used stages are dropped off the missile.

None of the things stated above are different for rockets, except for the fact that their are propelled at a different angle to put them into orbit. The same rocket with its payload replaced by the re-entry warhead becomes a missile when launched at different angle.

So much of wiki searching to prove us wrong, the opposite would have put your doubts to rest.

Thank you for your post, this is called reasonable answer, I think you should teach some of your indian fellow like that guys who said "Rockets can be change to ICBM with a bit software modifying." how to talk reasonablly.
Back to the topic, I got your point. With my knowledge about ICBM and space tech I cant find any wrong in your answer. And maybe some others will talking about these with you later, and I will notice this thread and find a result for me.

I think you should see eyes doctor, bcoz you are blind. I am sure I talked reasonablly but you are trolling here. And if your knowledge is limited to troll then I got that why your post always like shi@t in any other thread.

Trying to run away again from replying? Where did you got the info on your post that ICBM has to be armed with MIRV, maneuverable RV, decoy? You don't even know the meaning of ICBM. lol

You are just pretending not to understand something which is very clear! Indian rocket reaches the Moon which is 384,403 kilometres away from the Earth. We put satellites into Geosynchronous orbit which is 36000 km away. Our Agni-III can carry 2500 kg payloads to 3500 km away. Now every people with little common sense will understand that whether India can build ICBM or not. If you say, 'I will never believe that', thats something upto you.

Hold on, I don't concur, and you don't deserve all those thanks. Your geosynchronous orbit value is off by 6x10^3 Km. I have provided the calc below for proof:

Centripetal Force of satellite=mrw^2

Force on satellite acting from earth's center=GMm/r^2

Since the Force 2 is acting perpendicular along a tangent line of the circular orbit, we can say force no. 2 IS the satellite's centripetal force.

Hence, F1=F2.

Hence, GMm/r^2=mrw^2

In this sense, the mass of the satellite cancels out.

w=angular velocity, in radians sec^-1. Since there are 86,400 secs in a day, there are 2π/86,400 radians in a sec, canceling gives us π/43,200.

Now, GM/r^2=r(π/43,200)^2

Hence, 43,200^2GM/π^2=r^3

Solving for r, that is distance from center of earth to the satellite, it gives us ~42x10^3 KM. Since you're speaking of orbits, it's always given from a point source, that is, the whole mass of something is taken at a single point, the center of earth in this case.

No, I think you're just not worth his time. FTR, he never said ICBM's had to me armed with MIRVs. FTR, law of physics may be twisted around between Indian and Russia. E.g. USA uses imperial units whereas the Brits use the more modernized and international "Systeme de'international," or simply, "S.I Units."

I think he was talking about geo-stationary orbit. It's a commonly confused term.

PS: I am new to this website.

There was no need to do the maths, it is common knowledge that geo synchronous orbit is ~42k km.

 

[jha]

well according to him the similarity between ICBM and SLV is only that both fly off to sky...

 

[BelligerentPacifist]

"Agni-III design is frozen...it is the same missile but it is five metres longer and one tonne heavier.

...Agni-III...is 17 metres long, has a diameter of two metres and a launch weight of 50 tonnes. It can carry payloads weighing 1.5 tonnes.

... rocket motors - two metres in diameter, with about 30 tonnes of solid propellants in the first stage and nine tonnes in the second stage.

The numbers don't add up. The first 17m weigh 50t while a third stage 5m long will weigh only 1t!

Than all those guys who thanked me must be fools and you are the only only who understand this!

You deserve this sign '!'. OK for your sake, I bring the Geo orbit from 36000 km to 42000 km. Whats the difference? What it has to do with topic?Is it makes any difference about building an ICBM from GSLV? What you put are all 7/8th grade physics.

 

[lockh33d]

I think he was talking about geo-stationary orbit. It's a commonly confused term.

Actually it doesn't matter which term he uses, my calc proves true for both cases, considering the fact that the plane of orbit incorporates the center of earth as the center of orbit. He just needs to know that in physics, that point-point distance is the one we talk about, not surface-point.

Yes, you can fool the majority but you can't fool me. It has everything to the topic, because ICBM's have the power to be used as delivery systems to out space, and place goods in geosynchronous orbit.

Lastly, if you can't understand 7th/8th grade physics, what can you understand ?

 

[Kinetic]

No, I think you're just not worth his time. FTR, he never said ICBM's had to me armed with MIRVs. FTR, law of physics may be twisted around between Indian and Russia. E.g.

You pretend to be from US but can't read English read all the post multiple-time until you understand them. Don't waste our time.

Do you ever heard about GTO? and its differences with Geosynchronous orbit? lol

 

[moody]

There was no need to do the maths, it is common knowledge that geo synchronous orbit is ~42k km.

Geo synchronous orbit(GSO) is 35,700 KM exact.

While Geo stationary transfer orbit (GTO) is an elliptical path with apogee at 36000 km and Perigee of few hundred kilometers.
