The RV is same as A3. So its already flight qualified.
All those rectangles are patch antennas for telemetry.
The conical Third Stage is the grey/white portion with flag.
The copper/rust colored section is the adapter section or payload interface section which has the mission computer etc

See the raised band above the flag from the white section running aft is the conduit cover that protects the cabling. Its also called the cable raceway.

The RV is quite compact. Some of you might want to scale it with the avg height of people in the background but adjust for camera angle etc. If the body weighs 1.5 tonne then it sure packs a lot of weight for error correction or to go a long way!

Amazing the RV has a patch antenna on the nose.
Most likely an ablation sensor?

Bet all the folks are running hot expert opinion on that picture!!!
India is serious in releasing the picture.

Singha,depressed trajectory missiles aboard Soviet subs were of great concern to the US during the Cold War.,especially those from Soviet subs which had lesser ranges and were deployed closer to the US coastline.However,there was no accurate confirmation about this and later on the Soviets deployed their advanced LR ICBMs aboard Delta and Typhoon class subs safe and secure from their "bastions" in their Arctic bases.India having the capability of launching depressed trajectory BMs would complicate the task of BMD and be a real moodspolier to the enemy.

Both Agni III and V have a diameter of two metres, making them capable of carrying several warheads known as Multiple Independently Targeted Re-entry Vehicles (MIRV). (Agni I and II have a diameter of one metre and the first stage of the Agni IV has a diameter of 1.2 metres.)

Firing MIRVs requires what is known as a “Post Boost Control Vehicle,” a manoeuvrable platform that sits atop the rocket and holds the warheads. After the missile has lofted it into a ballistic trajectory, the platform must be able to release each warhead with the orientation and velocity needed to reach its target.

As India's Polar Satellite Launch Vehicle (PSLV) has already demonstrated the ability to put multiple satellites into orbit in the course of a single launch, developing a Post Boost Control Vehicle should be technologically straightforward. However, developing compact nuclear warheads could be a significant hurdle in acquiring MIRV capability. Published information on U.S. systems suggests that each re-entry vehicle will need to weigh less than 500 kg. First generation missile-borne nuclear warheads typically weigh twice as much.

So, from the article, it seems we have the MIRV tech ready and waiting in the missiles but do not have the maal which would be used for MIRV??

What sort of yield is the unitary warhead supposed to be packin? 150-200 kt fbf? Major political/security talks taking place with the US on the 19th.

Thinking more about the patch antennas, it looks they are for monitoring the aero loads during ascent. All those patches will get burnt up during re-entry.

sum, They first want to proof the AIII payload. Next they will proof the other versions once the basic configuration is proofed. Ideally they need two flights at max Q and max heating for the RV for statistics purposes. ie four successful consecutive flights.

If you re-read the ReDiff article I think they want to go one beyond MIRV to MARVs whenever the A5 is proofed for that role. The MARVs or rather BGRVs will defeat/challenge ABM systems.

Several things are happening at the same time.

PRC under pressure from all sides - South China Sea, India border (border exercise), US pacific ocean deployment
India testing its final version of ICBM for China and


Pakistan under pressure to yield in Af Pak and also resume talks and trade with India.


PRC preparing for a short border conflict in AP with India
Pakistan trying to support PRC with battle readiness in Siachen,


This may explain the avalanche in the ammo dump at the base camp of Siachen

CEP trident 1 is 400 m.. trident 2 is 100m..

50M for a 5000km + range is extremely impressive..

Ramana sir, RV is not same as A3. This RV is much leaner, i mean the L/D ratio. They simple brought down the second stage of A3 removing the inter stage gap and used that height of the gap + part of A3 RV height to build conical third stage. So RV is much leaner. Intention is clear. It is a MaRV.

All this makes me wonder if this version of Agni 5 will be deployed. It makes no sense to put a unitary warhead on a big expensive strategic missile , which will be a second strike capability and hence take out the max number of targets with whatever missiles survived a first strike.

So, I do think, this is an R&D missile at this stage that will get "operationalized" or even if it does , it will be in very limited numbers.

The "conical frustum" 3rd stage looks funny. I am not sure if that is so, or it is just the interstage tapering to fit a unitary warhead. The big enchilada , "full service missile" will have a conventional cylindrical 3rd stage, with a big enough base to house a payload adapter of a diameter large enough to house an MIRV bus and possibly housing 8 to 10 warheads.

Now that goes back to the basic question of fizzile or not at Pokhran II with the thermo-nuclear weapon. We will see to that question in the next versions of Agni V. If it has a MIRV bus with multiple warheads, the answer would be very clear.

This and the Arihant are serious warnings at PRC. A BTW, the Agni III and V series are totally "Shakinah" looking. They are true Submarine /Canister launch capable missiles (with minor modifications, bulk of missile being largely common for both land and sea versions).

Please explain the above.

In the whole buildup to Agni launch in media articles, 'China' as the target is being given way too much prominence. Not a diplomatically astute thing to do.

Assuming Indian TN is a no go, you can have following options or developments thereof.

French FBF warhead MR-41 - about 700 kg for 500 kt
Brits Bomb - 1800lb with an ‘unboosted fission’ warhead! ....Two core-boosted devices - Orange Herald (Large) and Orange Herald (Small) - had been drawn up....The small version had a target weight of 2000 lb Orange Herald (Small) achieved a satisfactory yield of 700 kilotons and the (Large) was never fired."
Amrikhan Zombie bomb not warhead - 1690 kt for 3450 kgs
Amrikhan Physics package - "Swan device had a yield of 15 kilotons, weighed 105 lb (47.6 kg)". My personal favourite to screw up everything.
Soviet RDS-6S (product 205K) warhead - 1800 kg for 400 kt carried atop an RSS (S-30)
SDRE warhead - 200 kt for 800 kg+

Hun tussi dasso, tvannu ki chaida?

Best of luck DRDO.

This foreplay is getting too much for me.

Navigational pods of strategic missiles are getting upgraded regularly. So what we hear from open source on CEP of various strategic missiles like Trident are old/obsolete values.

Similarly 50m CEP listed for Agni 5 are notional values. Real achievements may not be revealed.

On our stand on accuracy: We are mostly at par with the Superpower and trying to close the gap if any left.

CEP of Conventional Trident is listed as 10m a decade ago.

Along with depressed trajectory and MaRV, an ABM system encountering such combination will have a tough time in finding out missile's impact point. Instead of firing two interceptor missiles against a target( if that is the norm) it has to fire several interceptors and interceptors loose energy fast in encountering such system degrading further their Pk.

Doing a rough scaling of the A-V and taking along hard look at the Arihant,it appears that the A-V is approx 2m jn diameter.The ATV-1 has a hull diameter of around 14-15m,which is wide enough to accommodate two rows of silos which can accommodate an A-V diameter missile.The length of the A-V is a determining factor,as if it is larger than the hull of the ATV-1,a small hump may have to be fitted to the larger ATVs to accommodate the extra length of the missile.An approx. 1m difference is evident in the ATV-1s hull abaft the sail,meant to accommodate the 4 silos for the K-15s or single K series BM.The large "turtleback",as seen on the PLANs Jin class SSBMs,which carry 12 JL-2 SSBMs, may not be neccessary on an SSBM with an A-V ICBM.The hump could be smaller and less pronounced.

2 years back I had a talk with a retired missile scientist who worked with the prithvi. Doubts that the thermonuke detonation was a success. Says India will eventually have to test especially with the growing pakistani and chinese arsenal. Said it could happen as early as late 2012. I have my doubts though especially given the fact that we have so many nuclear projects on the table and are bound by a few international agreements.

Read together with (from the same report)
Quote:
V.K. Saraswat, Scientific Adviser to the Defence Minister, told The Hindu, the launch will mark a “historic day.” “Agni-V is a game-changer and a technological marvel. It is a weapon which can perform multiple functions.” It could be used for anti-satellite capability, for putting micro and nano satellites in orbit and carry multiple warheads.

Dr. Saraswat said it was comparable to the missiles of this class developed by the U.S., France, Russia and China.
To understand the true capability of A5, look up the details of any comparable missile in the same weight and size class.

Quote:
He said the performance of the systems during the phase three and four tests had been good and satisfactory.
What phase 3 and 4? Did A4 have a MaRV or am I reading too much?
