Agni-IV test-flight a ‘stupendous success'


A4_ii__837169e.jpg



The test-flight of Agni-IV, India's most advanced long-range missile was “a stupendous success” on Tuesday, with the missile covering a range of more than 3,000 km in 20 minutes of fluent flight.

This was the longest range mission flown by the Defence Research and Development Organisation (DRDO) so far. Agni-IV, capable of carrying nuclear warheads, was earlier called Agni-II Prime. The first flight of Agni-II Prime in December 2010 was a failure.

As the Sun shone on the tiny Wheeler Island, off the Odisha coast, Agni-IV lifted off majestically at 9 a.m. from a specially designed truck, accelerated to a height of 900 km, sliced across a distance of 3,000 km and accurately reached the targeted area in the Bay of Bengal. As it plunged into the atmosphere, its re-entry systems withstood a searing 3,000 degrees Celsius. Several radars and electro-optical systems along the Odisha coast tracked the vehicle.

The two-stage Agni-IV, which weighs 17 tonnes and is 20 metres long, carried an 800-kg payload of conventional explosives. However, it is designed to carry a 1,000-kg payload.

In this mission, the DRDO used a host of new technologies for the first time. Agni-IV “has opened a new era” for India in the class of long-range missiles to carry strategic [nuclear] warheads for the armed forces and “provides a fantastic deterrence,” DRDO missile technologists asserted. “Strategically, it can cover the whole area on the other side of the border [China],” they explained.

V.K. Saraswat, Scientific Adviser to the Defence Minister, called it “one of the most stupendous missions.”

The launch had put India in “a different league” because “the kind of technologies we used in this flight are different from those we had developed in the 1980s and 1990s.”

Dr. Saraswat, who is also the DRDO Director-General, said: “I will say that India does not need any foreign assistance for surface-to-surface missiles of this class.”

yes it is, as you remember it was said Agni V test is depend on success of prime after looking it's accelerated height range seems to me as 5000+.

Yes yesterday i watch some where in TV (ETV news Odiya)that range is about 6000km but try to google every where it's written 3500 km.:yahoo:
 
from Agni 3 missiles and beyond use better RV's and better navigation systems the technology has significantly progressed from the original 80s' and 90's

i think that next year we should test all of the Agni missiles to certify there credibility

Normally, a missile wouldn't go beyond 250-300 kms height during its journey... The extra height was given just to check and validate the precision levels by giving it a skewed(stretched parabola) flight path...

the confusion stems from the fact that it's range is touted as 3000KMs, but it's not clear if the missile itself travelled the full 3000kms during the test.
So, whether the missile can travel 3000kms+ when given a 'normal' trajectory to it or inspite of being given such a height, it travelled 3000kms so it can practically travel much larger distances of ~4-5000 kms is the issue.

Another important factor is, the missile can carry a payload of 1000kgs but was given only 800kg during the test... so the payload is another factor here...

IMO : it is the latter case.... and when you factor in full payload weight it will have an effective punch within 3500kms range is how it should be interpreted.
 
I'm curious. Whenever a country tests its ballistic missiles, the test will be detected by satelittes and radars around the world since the missile has to travel out into the atmosphere, is that correct?

Thanks

Yes it is possible but only through dedicated surveillance sats only... and i think drdo would have had done their calculations before ....

What is dedicated survelliane sat?

What about radar installation around the world, don't they pick up an object that shoot that high ino the atmosphere?

This means that the speed of the missile is 3000000 / 1200 = 2500m / sec. which is about 7.5 TIMES faster than the speed of sound i.e 330 m / sec.

WoW what a great success !!!

Looks like a missile made by Rajni Kant industries !

It means a satellite which has been assigned only surveillance role...

Yes, through a chain of radar installations around the trajectory, the flight details like speed/ height / other stats can be collected. IMO this is what DRDO does to validate flight parameters for a missile...

It is no doubt a great success but such speeds are common for missiles of large ranges.... some russian/chinese missiles have been known to touch speeds of 13000 km/hr speed in terminal phases... ie. ~3500 m/s ie 11 Mach

ps. It will be extremely difficult for a quick reaction missile to touch such high speeds in short time. That is why it becomes impractical to design a terminal phase ABM shield for ICBMs...

I heard US/NORAD have the capability to pick up every single launch by every single country.

Anyways its before every launch the neighbors are informed, the area where the warhead is expected to fall is 'sanitized' and I think even IATA is notified so that airlines passing through the area can take necessary precautions.

You are over stretching here ...
I think the range of the missile as quoted here is scalar i.e 3000KM.
The actual distance traveled by the missile , first going up through the atmosphere and then down is much larger than 3000KM.

Either the paper mis quoted the time and distance of flight, or there is some thing else wrong here ...
