Agni & Prithvi Ballistic Missiles : News & Discussions

Is the facility expansion to handle all these and hiring of talent pool, not happening at good enough pace?
I mean technology maturity wise it takes some time before it is ready for application, then again another long period to be satisfied with similarity between expected result & delivered result. Hence so much test go on. First crmc stage was the slim A4 2nd stage K4 first stage then A5 2nd stage. Then many static firing to gather data , pressure thrust inner temp isp various matrices. Then gradually scale up via prime, , full composite K4 A5 etc. You can see step by step progress and maturity.
 
Yes.
India has boosted fission weapon design.
The. deuterium bit produces more neutrons for higher percentage of fission.
Not much explosive energy.
The reflectors and shielding parts are heavy. Which are used to reflect the neutron back into the fissile materials.
However I am not sure why you say pure fission warhead is lighter than boosted fission?
Usually it's the other way round?
Depends on yield chachu. Of course 200 kiloton boosted fission will be much bigger in weight than 12-15 kiloton pure fission. Despite having deterium and other elements to boost the yield, more plutonium and plastic explosives are needed for a boosted fission design of a higher yield.

Radiochemical analysis of the test site ground zero is the most accurate way of determining whether the design was successful; the results and details of this test is secret as it can reveal some clues about the design. Fortunately, BARC and later PK Iyengar (who was initially skeptical about our fusion test) saw the results of this test and concluded our fusion weapon worked. So we likely have hydrogen bombs which can be scaled up to 200 kilotons if needed. Anything beyond that, highly unlikely to have been developed. And if it is, it needs testing to show it works. Otherwise, scaling up a proven design is not hard, the Yanks deployed a whopping 25 megaton warhead which was scaled up version of the 15 megaton moster they blew up in Castle Bravo.

Actually not like that. As the technology base go, we are in a transition period across multiple technical domain. In electronics package, wiring, pcb, additive mfg of the internal mounting brackets racks, material side, high energy propellant, crmc, al alloys, insulation cover rubber sheet bonding material, ablative coating, material for control surfaces, uhtcc coating for the same, safety arming , fuzing, new gen obc, small thruster, small miniaturised DACS & RCS all are going across different make versions. hence lots of test are actually static and ground level tests. The campaigns 1 2 3 etc most are tested in STF ground level. Actual flight tests are high cost affair so only after satisfying many data point does a project move into flight test phase.
Today critical systems flight test will happen once every 2 years due to so many projects. Earlier in the 1990s it was only A1 A2 and prithvis. Now there are so many strategic systems and comes with all aspect ie canisterisation, health monitoring, high level NDT NDE, heavy vehicle, rail system, support vehicle, deployment on naval side all these things are huge workload.

Dhvani is too wide to have its own fairing.

This must be the Agni 5 variant you are talking about.

No cou nary make megaton range bombs anymore. It's wasteful as most of the energy goes upwards and causes no destruction.

A5 mk2 juice that makes it go brrrr to a very long distance. Very sad people can not recognise. :sleep::cry:

anyway , comeback king ? :sneaky:;) we shall see :censored::devilish:

K-15 programme was a revealation as far as novel propellants are concerned. It all went up from there even for our Agni series;)

During those days the solid fuel used gave about ~ 226 s Isp, hence much lower thrust. Today the current make fuel is around 254 s and the upcoming NG is more. So bound to have improvement. Not surprising to see a conventional use solid fuel BM is unveiled. This was unthinkable even in the last decade.

Yup world is shifting towards 400-500 kiloton nukes for most uses but China for whatever reason apparently still deploys a whopping 5 megaton nuke. Shows their mentality. Even USA has a max deployed yield of 1 megaton now and that's mainly for bunker busting purpose.

On topic. Since delivery platform accuracy has increased, the need for building large nuclear weapons destroying large areas isn't there anymore.
Countries can select and target specific enemy territory for nuclear weapons,

How about your two Abbus , Israel and Russia?
At least we have one abbu.

Israelis are interesting they tested only once. Seems like they got warhead designs from Frencies for other yields. They probably don't have megaton range nooks. Russians rely on 700 kiloton weapons iirc, they have some megaton range weapons deployed too. Their Poseidon has 6-10 megaton nuke. BTW they aren't our abbu cuz we don't need money and shyt from them. We pay them good money for whatever we want, so theyre more like you're local trader lol. Can't say the same about relations between you and China, where money flows only one way, other way something else flows 🙂🤭.

I think Cheenis will still use megaton range because while their ICBM are accurate their HGV are not, their 2021 HGV test missed target by 40 km. So theyre gonna deploy megaton range nukes on their HGV but that means speed will be less as payload will be heavier. Our scientists in 1980s knew we had only 12-15 kiloton nukes so they made Prithvis highly accurate, it had less than 50 m CEP way back then itself (albeit we used western chips like Intel on the guidance package). BTW what's the CEP of your missiles Ghauri Shaheen Ababeel? I haven't seen figures for their CEP anywhere.

Megaton bombs (1-10 M typically) are still useful for using in EMP configuration, as they cover very large area, so much numbers are not required, and if target is nearby your borders there is always risk of spillover to country who launches these.

Nooks as emp !
Imagination running hard. At least think about the fallout part.

ps: it seems we have managed to miniaturise the deliverable payload into 1:4 ratio quite a while ago, like 10 years+ ago. Which and what yield I do not know or tell. if its from the 2000-2010 vintage then ...

If its detonated outside the atmosphere then fallout cannot be produced. It's mainly produced when it's detonated at or close to surface afaik.

Also sir what do you mean by 1:4 ratio and 2000-2010 vintage?
 
300-400 kiloton weapons can also create strong EMP effects.
Depends what one's target is, Big brothers are bigger in Area also, thus they need more energy per SQ meter. Being a lazy person I'm just gonna reproduce relevant text from Wikipedia:

Weapon yield

Typical nuclear weapon yields used during Cold War planning for EMP attacks were in the range of 1 to 10 Mt (4.2 to 41.8 PJ).[35]: 39  This is roughly 50 to 500 times the size of the Hiroshima and Nagasaki bombs. Physicists have testified at United States Congressional hearings that weapons with yields of 10 kt (42 TJ) or less can produce a large EMP.

The EMP at a fixed distance from an explosion increases at most as the square root of the yield (see the illustration to the right). This means that although a 10 kt (42 TJ) weapon has only 0.7% of the energy release of the 1.44 Mt (6.0 PJ) Starfish Prime test, the EMP will be at least 8% as powerful. Since the E1 component of nuclear EMP depends on the prompt gamma-ray output, which was only 0.1% of yield in Starfish Prime but can be 0.5% of yield in low-yield pure nuclear fission weapons, a 10 kt (42 TJ) bomb can easily be 5 * 8%=40% as powerful as the 1.44 Mt (6.0 PJ) Starfish Prime at producing EMP.

The total prompt gamma-ray energy in a fission explosion is 3.5% of the yield, but in a 10 kt (42 TJ) detonation the triggering explosive around the bomb core absorbs about 85% of the prompt gamma rays, so the output is only about 0.5% of the yield. In the thermonuclear Starfish Prime the fission yield was less than 100% and the thicker outer casing absorbed about 95% of the prompt gamma rays from the pusher around the fusion stage. Thermonuclear weapons are also less efficient at producing EMP because the first stage can pre-ionize the air[37] which becomes conductive and hence rapidly shorts out the Compton currents generated by the fusion stage. Hence, small pure fission weapons with thin cases are far more efficient at causing EMP than most megaton bombs.[citation needed]

This analysis, however, only applies to the fast E1 and E2 components of nuclear EMP. The geomagnetic storm-like E3 component of nuclear EMP is more closely proportional to the total energy yield of the weapon.



By the way Early test conducted by USSR used 300 KT Nuke.

I think workable solutions for NEMPs are already available with Big-3 at least. If enemy can be brought down to it's knees by exploding nuke/s at thermosphere, it is much better then air/ ground burst.

Real imagination may look like this : If these can be used as ASAT for taking down LEO satellites in bunch in some specific cases (I think that these satellites have excellent EMI/EMP withstanding capacity, so may be nigh impossible).
