5 Variant till date. 3 are operational and 2 are under development trial. One is in design stage.

I meant. How many Agni 1, Agni 2,Agni 3 annually are manufactured by DRDO ??

"The test firing was a total success. The missile travelled its full range," M V K V Prasad, the director of Integrated Test Range, said.
India today successfully test-fired its nuclear—capable strategic missile Agni—IV, with a strike range of about 4000 km, from a test range off the Odisha coast.

“The test firing was a total success. The missile travelled its full range,” M V K V Prasad, the director of Integrated Test Range, told PTI.

It was test launched from the launch complex—4 of the ITR at Wheeler Island, at about 10:52 AM, defence sources said.

A high performance on—board computer with distributed avionics architecture, a high speed reliable communication bus and a fully digital control system were used to control and guide the missile to the target, the sources said.

“It is equipped with modern and compact avionics to provide high level of reliability,” a DRDO official said.

“The state—of—the—art Ring Laser Gyros based high accuracy INS (INS) and Micro Navigation System (MINGS) complementing each other in redundant mode have been incorporated into the missile system in guidance mode,” the sources said.

The sophisticated missile is lighter in weight and has two stages of solid propulsion. The payload, with a re—entry heat shield can withstand temperature of more than 3000 degree Celsius, a defence scientist said.

The missile is undergoing developmental trials by the DRDO.This is the third development trial of Agni—IV missile by the DRDO.

Radars and electro—optical systems along the coast of Odisha have been positioned for tracking and monitoring all the parameters of the missile.

Two Indian naval ships were anchored near the target area to witness the final event.

The last trial of the missile was carried out successfully on September 19, 2012 from the same base.

But that need higher budget allocation.


DRDO is planning to employ 500 more scientist in next 1 year.

What is present budget allocation?Now engineers in DRDO is about 7000-8000 range .We need to increase in to at least 20000-25000 range within few years.Even ISRO has 16000 engineers.

DRDO has 50 laboratories under it so its about 160 engineers per lab,Not bad,is it?
From where did you get the data for ISRO?

We actually need more engineers in field of metallurgy,lasers,semiconductors,silicon chips e.t.c.........

More so considering the fact that DRDO has 50+ labs by different names for different purposes.

5% of defense Budget and 1% of total spending on defense R & D of world. US spends more than 10% of defense budget and China 20%. Chinese defense budget being 3 times of India, Indian R & D spending is 1/12 times that of China i.e 8.3 %.

Aerodynamics also.

I read it in article when the ISRO chairman address IIST in valiyamala.

More over we must increase our budget for R&D.must be increase to 10% of defense budget.

Ignore China they are competing US .So they may spend like that.We dont need to race with others.But what we make with our small resources, we must do it excellent way .Our DRDO a commendable job with this small resources.

If we want to indiginized our defense products, We must increase defense budget in R & D.

 

[SrNair]

If we want to indiginized our defense products, We must increase defense budget.

.you are right.Defense budget for R&D.And for that we need to increase caliber of our economy.

For Accuracy, 2 or More system work in redundant mode to offset error.

Can you please elaborate Point No 9?

All Composite A V is in making.

Higher Thrust to Weight Ratio
On October 8, 2010, Director-General of the Defense Research and Development Organisation (DRDO) V.K. Saraswat said that Agni-II Plus, a modified version of the Agni-II strategic missile, has a higher range, higher performance, with respect to the thrust and weight ratio than Agni-II, which has a range of 2,000 km.


Extra Fuel
The missile is now rumored to carry extra fuel and a high altitude motor in its re-entry vehicle (RV) to allow for greater range or terminal maneuvering.

The reference to "special weapons" and on-board thrusters in an Indian Express report probably allude to a maneuvering or extended range warhead.

....................


Analysis
Speaking to the press on November 16, 2011, a day after the first successful second test of the missile, DRDO Chief VK Saraswat compared the Agni-IV to the US Pershing missile.

Some of the salient features of the Pershing-II missile that has now been retired were

1. Kevlar (composite) rocket motor, which the Agni-IV does have.
2. A maneuvering re-entry warhead, which the Agni-IV is rumored to have.

The Pershing-II missile used radar co-relation terminal guidance. A small radar placed ahead of the warhead was switched on during terminal phase and used to obtain a picture of the target area that was compared with stored imagery uploaded before launch. The delta computed from the co-relation was used to update the inertial navigation system in the missile. The warhead would then maneuvered using its fins to refine the trajectory. As a result, the missile could achieve a CEP of 30m.

In case of a failure of the radar co-relation system, the warhead relied solely on its inertial navigation system.

Here are some thoughts

1. No fins are visible on the Agni-IV warhead so any terminal maneuvering would rely on a small rocket motor fitted with a flex nozzle. According to rumors, Agni-IV has just that.
2. Theoretically, India could obtain radar imagery of targets in China and Pakistan using its RISAT satellite.
3. Without terminal guidance, Agni-IV could not possibly be as accurate as DRDO has been hinting it is.

The question is, does Agni-IV use terminal guidance? What is the nature of the terminal guidance used? Is the MINGS used for terminal guidance? DRDO has said Agni-IV's RINGS and MINGS operate in tandem and complement each other in a redundant mode. Which sounds like the terminal guidance on the Pershing-II missile.

Any terminal guidance like the one employed on the Pershing-II missile would need to be tested on a land target. Interestingly, no DRDO missile has ever been tested on a land target.

I thought we spend 6% of our defence budget on R and D......

5.2 percent of defence budget is spend on R & D to be exact
defence minister wants to raise this cap by another 2 percent to around 7
china sepnds 20 percent of its defence budget on R&D while USA sepnds around 16 percent

Broadsword: DRDO chief wants 7% of defence budget for R&D
