Nuclear competition among China, India, Pakistan could escalate

WASHINGTON: Small increments of stockpile growth and multiple warhead missiles will ratchet up a triangular nuclear competition among China, India and Pakistan , a new book has said while warning that there are no realistic prospects for banning such arsenal.

With China beginning its long-awaited deployment of the DF-5B intercontinental ballistic missile, India and Pakistan are likely to respond by placing multiple warheads atop some of their missiles, the book titled 'The ..

Firstly, DF-5B is an aged liquid-propel missile. The deployment of this weapon is making political sense rather than military sense;
Secondly, unless India and Pakistan start new round of nuclear tests for minimizing warhead, it is pointless to talk about MIRV.

It is saying China started the arms race in Asia .what is political about it?

India's Next Ambitious Programme upcoming AGNI VI , which is currently approved with design to deliver more than 10 war heads and is expected to have MIRV [Multiple Independent Re-entry Vehicles] and MaRV [Maneuverable Re-entry Vehicle]

The Agni VI will be sleeker than the Agni - V with will have Four stage Solid fuelled engine.

The missile design has been completed and DRDO is in the hardware realisation phase.

Last I heard after successful launch of Agni V in 2013, that Jessy Thomas (Missile Woman of India) will be leading the development of MIRV Technology herself.

Is anybody aware of the current position we are in?, for the development of MIRV and MaRV techonologies

IMO the mirv'd missile is ready , testing will be a political decision to deliver the biggest bang for the buck. The multi satellite launches are a testament.

The multi satellite launches are a testament of only part of it!
You will need a new small size nuclear core first, then a new minimized re-entry vehicle with all new developed electrical components and heat-proof material. Each of them need lots of work to do.
As the beginning, start nuclear test again.

The satellite launch is technically more difficult than the missile. Imo the missile work was done long before satellite launches.

India’s Defence Research and Development Organisation (DRDO) is reportedly validating technologies that will help India deploy multiple independently targeted reentry vehicles (MIRV) warheads on its missiles.

The DRDO has confirmed it has made significant progress over the past few years in developing an indigenous technology for the single-rocket-multiple-warhead system, and DRDO expects this ultimate war machine will be ready in another three to four years (2018-19).

Scientists of the organisation claim the guidance system will have a high degree of accuracy to offset even a small circular error of probability or a negligible deviation from the intended target.

Agni 6 is three stage not 4 & SLBM version has third stage in nose fairing

I have reference from wikipedia which says.. A6 to have range between 8000 - 12000 kms

yes but with less payload probably same as agni 5 & 5000 km range with 3tn payload

Opposing to what you believe, missile technology is always difficult than launching a satellite because
1. missile is generally required to launch in short notice while satellite launch can get weeks or even months prepare time;
2. Missile maybe required to launch in any weather condition while satellite launch can wait for good days;
3. Missile may be stored years after being assembled while satellite rocket only waits months;
4. Missile requires lot higher speed than Satellite rocket in case of enemy attack in ascending stage.

The reason that missile work was done long before satellite launches is lot easer to simplify a missile to satellite rocket than designing a missile on the basis of satellite rocket.

Reentry vehicle with heat-shield is there in the nuclear-capable Agni-III also. IMO the key technology to realise with MIRV is deploying multiple war-heads from the booster vehicle with precision timing.
In case of MaRV, though, additional requirement will be self-propelled war-heads with inertial navigation.

Are we currently signatory to any treaty which curtails it? In my humble view, there was some sort of non-weaponization-of-space agreement we signed with US when Obama was in India. I think it indirectly targets MIRV type weapons as space weapons as they are of exo-atmospheric nature. Maybe there are finer clauses even within MTCR which would impose additional restrictions on us, if not about testing then about giving missile tech to other nations. So we should do this test and pass on whatever tech we intend to pass on to Vietnam and Argentina before we get into MTCR.

India, as a nation, does not vote on national security issues. That is not a card one can play, unlike the minority card. Take the example of 26/11 attacks in 2008. People still voted for Congress in 2009, both in central government and in state assembly. We should test as soon as it's ready without wasting a moment for political reasons.

India’s Defence Research and Development Organisation (DRDO) is reportedly validating technologies that will help India deploy multiple independently targeted reentry vehicles (MIRV) warheads on its missiles.

The DRDO has confirmed it has made significant progress over the past few years in developing an indigenous technology for the single-rocket-multiple-warhead system

We already have that system, that is what we use to launch multiple satellites through just a single rocket. The tech is there, they are probably just validating it, or maybe that is done too. No agency reveals what its working on unless it is already done. "We are working on.." usually means "we have successfully completed" in diplomatic parlance. It's a message to the other powers, more than the domestic audience.

With a 3 ton MIRV warhead, the range of Agni 6 will be 5000 km. However, with MaRV, the self-propelled warheads can potentially travel 1000 km further, making the effective range 6000 km.

Hypothetically, one could build a system, where after re-entry, each munition would act like a standoff weapon, and glide towards its target, with its course being guided by GPS. Terminal velocity of an aerodynamic projectile could go well over 200 kmph.

That is what MaRVs are supposed to be; China perfected it in 2006.

No, the heat-shield for returning satellite or warhead is consuming the heat by burning off itself. It is just like the ice, when you touch the ice with your hand, the ice will melt and turn your hand to cold at the meantime. So, here, the burning rate and weight are the key for heat-shield.

When you are replacing the single warhead with MIRV, you generally will need a smaller and lighter warhead, which will require a lighter and thinner heat-shield. So you will have to develop a new heat-proof material which will be not only lighter but burn at a lot slower rate.

That only prove your navigation capability. MIRV needs lot more than that.

The tech is there, they are probably just validating it, or maybe that is done too. No agency reveals what its working on unless it is already done..

MIRV is not kind of weapon you can test in the lab for every single subject.
The critical part of experiment need to be done in real launch. So, as soon as you do it, others will know

It is not the case. Even decades old technique of covering the US Space Shuttle with Silica Tiles worked and the shuttle returned unburnt. For MIRV, SHARP materials (there are quite a few) capable of withstanding 3600° C at Mach 11 are used. Even Ceramics are good heat-shields. Heat-shields for warheads are minor issues; main is deployment and homing.
