Agni-IV and Agni-III launch, September 2012

[Bheeshma]

Agni-III is heavier due to maraging steel while the A-4 is a new gen missile with composite motor casing. A-4 technologies will be used in A-5 not A-3. A-3 is simply stop gap. Like A-1 was rushed into service and will be replaced by Shaurya. The A-4 went to 3000+ km despite have a very steep trajectory. Clearly shows the real range is higher. TSS already mentioned 4000 km range though he left out the payload.
PS: Calcutta to Beijing is <3500 km.

Agni III is the first step towards SLBMs. Agni II and Agni IV form the "sleek" missile component. DRDO plans on developing both classes of missiles in future versions.

Agni III's weight is not due to the difference in engines, but fuel loads. We are talking about a 2.5 ton payload compared to a 1 ton payload on Agni IV. Engines have extremely high thrust to weights. A marginally heavier engine does not equate to a 30 ton difference.

Also, every single missile of the Agni series has been crucial and not a stop gap to any other missile.

Agni I is being replaced by the Shaurya only because Agni I is old and obsolete. Agni III will give birth to our first SLBM, the K-4. Agni V is our first near ICBM missile.

Agni VI or VII may be used as a second class of missiles for our SLBM program and the other being a full fledged ICBM. This time will tell.

 

[Bheeshma]

Agni-III will be the base but K-4/5 etc will include the composite case and tech from A-4/5 as weight is an important criteria for SLBM's. A-5 is an evolution of A-3 like A-4 is an evolution of A-ii (legacy). But that does not change the fact that A-4's range is 4000 km. Agreed it cannot throw 2.5 tonne but a single maneuvering RV should not weigh more than 500 kg.

Yeah, ok. It doesn't mean much of anything though.

P2P, please tell me why, A4 is burning extra fuel at tax payers expense and achiving same thing which can be deplicated by A3 without going that height?

 

[sayareakd]

IMHO A1 & A2 are same tech, A3 was new missile they smartly give it A3 name. A4 is new tech & A5 is our ICBM. Again DRDO played it smartly, with range, name and all the mis information about it. Final result not much noise is made by any one except China.
What will be interesting in this test of A4 would be range and altitude. It has already gone pass 3k, hope this time it touch 4k, to show Panda we mean business.

Payload.

Can you compare GSLV to PSLV?

 

[Apollyon]

Agni-IV for ASAT and delivering single MaRV warhead.
Agni-III/V for delivering MIRV/multiple MaRV.

Long range strategic missile Agni-IV test-fired

Balasore (Odisha): India on Wednesday test-fired its nuclear-capable strategic missile Agni-IV with a strike range of about 4000 km from a test range off Odisha coast.

It was test launched with the help of a mobile launcher from launch complex-4 of ITR at Wheeler Island, about 100 km from Balasore, at about 1145 hours, Defence sources said.

A high performance on-board computer with distributed avionics architecture and high speed reliable communication bus and a full Digital Control System were used to control and guide the missile to the target.



"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 (RINS) 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 country's premier Defence Research and Development Organisation.

The last trial of the missile, carried out on November 15, 2011 from the same base was successful.

NEW DELHI - India test-fired its second-longest-range missile on Wednesday, a defence official said, two days after Pakistan announced its own missile test.
The two-stage Agni-IV blasted off from the eastern state of Orissa in the third test for the missile, which was first launched in 2010 in a flight marred by technical problems. Its second test last November was declared a success.
"The Agni-IV was tested for its full range of 4,000 kilometres (2,480 miles) and it was a success," Defence Research and Development Organisation (DRDO) spokesman Ravi Gupta told AFP on Wednesday.
Pakistan, which has fought three wars with arch-rival India since their 1947 independence, test-fired a nuclear-capable cruise missile on Monday with "stealth features".
DRDO spokesman Gupta insisted India's test was not "country-specific".
"None of our missiles are country-specific. We are a peaceful nation which has never attacked any country in thousands of years," the DRDO spokesman added.
India unveiled its 5,000-kilometre range Agni-V in April, which was seen as a massive boost to its regional power aspirations and one that narrows -- albeit slightly -- the huge gap with China's missile systems.
The Agni-V left India knocking at the door of a select club of nations with inter-continental ballistic missiles (ICBMs), which have a minimum range of 5,500 kilometers.
Currently only the five permanent members of the UN Security Council -- Britain, China, France, Russia and the United States -- possess a declared ICBM capability.
China and India fought a brief but bloody war in 1962 over a border dispute that remains unresolved despite several rounds of talks between Asia's two most militarily-powerful nations.
Agni, which means "fire" in Sanskrit, is the name given to a series of rockets the DRDO developed as part of its ambitious integrated guided missile development project launched in 1983.
While the shorter-range Agnis I and II were mainly developed with traditional rival Pakistan in mind, later versions with longer range reflect the shift in India's focus towards China.

Agni IV is a 2500Km missile. Agni III is a 3500Km+ missile and is meant to carry a very large payload, maybe even MIRVs once ready.

Agni IV is something like a Agni II Mk2 with better guidance and maybe a little better range.

P2P please check this news article

India on Wednesday successfully test-fired nuclear weapons capable Agni-IV for its full range of 4,000 km from the Wheeler Island, off the Odisha coast.

The missile lifted off from a road mobile launcher at 11.48 a.m. and after zooming to an altitude of over 800 km, it re-entered the atmosphere and impacted near the pre-designated target in the Indian Ocean with remarkable degree of accuracy following a 20-minute flight.

Carrying a payload of explosives weighing a tonne, the missile re-entered the atmosphere and withstood searing temperatures of more than 3,000°C.

The developmental trial of the long range ballistic weapon system was conducted by missile technologists of the Defence Research and Development Organisation (DRDO), which designed and developed it.

Talking The Hindu from Wheeler Island, Scientific Advisor to the Defence Minister V.K. Saraswat said " we had an excellent launch". He said the two-stage solid-propelled missile performed as per the normal parameters right from the lift-off till the terminal event when it impacted the target point with a "two-digit" accuracy. He said the data showed that the missile followed pre-determined path with an accuracy of less than 100m. Two naval ships located down range recorded the trajectory of the missile and the terminal phase and transmitted the data in real time. He said the success of the mission reinforced the robustness of the design and various subsystems.

Dr. Saraswat said Agni-IV would be inducted into the services next year after undertaking one more developmental trial. He said, "The mission confirms reliability and robustness of the missile. It demonstrates India's missile technology has become highly mature and we can now design any missile for any mission, depending on the threat profile. Technologically, today we are at par with the best in the world. We have complete industrial infrastructure which helped us to realise Agni-IV".

He said the series of successful missions — Agni-V, followed by Agni-I, Agni-II, Prithvi-II and Agni-IV now showed that these missiles could be launched on demand in a very short time.

Avinash Chander, Chief Controller (Missiles and Strategic Systems), DRDO said Agni-IV was tested in its full operational scenario and the missile fully proved itself in all respects. He said the deliverable road mobile launcher configuration was also validated in this mission. Observing that it was one of the lightest long-range missiles of its class, he said it would be a potent addition to the strategic forces.

Tessy Thomas, Project Director for Agni-IV, said it was an excellent flight and met all the parameters up to the final event. It was a text-book launch for the second consecutive Agni-IV mission, she added.

Meanwhile, the Strategic Force Command personnel will launch nuclear weapons capable Agni-III surface-to-surface ballistic missile on September 21, 2012 as part user training.

[p2prada]

Yeah. I noticed. I also noticed there was lesser altitude, which means lower reentry speed.

Congrats to our scientists.

Agni IV is a 2500Km missile. Agni III is a 3500Km+ missile and is meant to carry a very large payload, maybe even MIRVs once ready.

Agni IV is something like a Agni II Mk2 with better guidance and maybe a little better range.

Ok. Let's add another 500Km to it.

But don't compare it to the Agni III. This is a different class of missile meant for carrying a different class of weapons.

Btw, this article has a mistake. It says Agni IV has a RLG, but it actually has an optic nav.

It's not a right comparison. Different flight trajectories can be used to achieve different objectives during reentry. Even warheads can be ejected at different trajectories from the same missile using MIRVs.

For eg: Shaurya can follow three completely different trajectories and flight patterns to achieve entirely different objectives and can extend the missiles range from 700Km to 2000Km depending on the trajectory.

I explained the same even for BVR missiles where a Aim-120D can have a 120Km range or a 180Km range depending on the trajectory of it's flight.

So, if an Agni III re-entered after a 300km altitude then it was trying to accomplish something different compared to Agni's 900Km altitude.

Btw, if you did not notice in that simulation in the first picture, Agni III achieved a range of 1300Km, not 3500Km.

Yeah, ok. It doesn't mean much of anything though.

In the two videos, Agni III accomplishes a greater range with a much larger payload and uses a combination of high kinetic energy and gravitational acceleration to propel the warhead faster compared to Agni IV's reliance on only potential energy.

The extra altitude only reinforces the belief that is is less superior to the Agni III. But then it accomplishes an entirely different objective by allowing greater re-entry speeds that if it followed Agni IIIs trajectory. So, like I said, different trajectories for different objectives.

You can assume the Agni III took a shorter amount of time too.

Payload.

Can you compare GSLV to PSLV?

Yeah. I noticed. I also noticed there was lesser altitude, which means lower reentry speed.

sir never say die attitude

you can have great future in law

 

[Bheeshma]

LoL He is still clutching at straws. Anyway so TSS was right 4000 km was for 1 tonne payload. With a smaller payload the range can go to 4500 km easily.

first test was for 3k this one is for 4k i think it can reach 5.5k.
