HYDERABAD: In a major technological breakthrough that will drastically reduce the weight of missiles and enable them to reach longer ranges with heavier payloads, DRDO scientists have developed composite rocket motor casings.

Only the United States, Russia and a European consortium have achieved a similar feat. Faced with denial of advanced technology by the Missile Technology Control Regime, the scientists from DRDO’s Advanced Systems Laboratory, Hyderabad, developed it in four years.

ASL Director Avinash Chander told The Hindu here on Friday: “This is a major breakthrough, which provides us the key technology to go into longer missions with lighter weight.” The first large composite motor with carbon filament winding was realised after it was subjected to “full qualification and static tests.”
Metallic casings

Most of the missiles today had metallic rocket motor casings made of maraging steel or other varieties of steel. With weight being a critical factor, the trend world over was to move over to composite carbon filament wound motors. “Our aim is to have as low a weight as possible,” Mr. Chander said.

Pointing to the advantages of CRMC (composite rocket motor casing), he said they would reduce the weight of a rocket casing by 40 per cent, enabling the missile to take heavier payloads. The payload equivalent to the weight reduced could go up or the range of the missile could be increased. Or a combination of both could also be achieved.

Other major benefits include cost reduction by half compared to metallic casings, better performance and long storage due to non-corrosive nature of the material. The flight trial of a missile with the CRMC would “happen shortly.” K. Jayaraman, Director (composites), ASL, said the development of the CRMC in four years by the ASL was much shorter compared to the development of similar technology elsewhere in the world.
Agni programme

Mr. Chander, who is also the programme director of Agni, said Agni-III was built with a lot of potential to take higher payloads. The same missile could reach ranges of more than 5,000 km with minor modifications in the system.

Recently USAF F-16 hit an BM with a AIM-9x. Solutions are already moving from land based to other forms. It is would naive to think BM cannot be intercepted in the future.

NCADE seeker equipped AIM-9X missile concept is for the time being a bull ****... Knowing where the missile is getting lauched from, getting in way on top and shoting the BM in boast phase .... Give me a break.

Range of AIM-9X --- 20km tops, yes , so the missile loaded F-16 should be in 50km range for interception... Should know when someone is going to lauch and from where it is going to be lauched from...

In a tactical environment no chance for such detection and preception. Its only a conceptional validation. Boast phase intercept without prior information of BM lauch site and available Fighter in nearby location is Bull ****...

A boost phase interception from more than 200 kms in real senario is right now impossible considering flight time required by the Intercept missile, You might even need to lauch the interceptor before the missile is launched.

BM will enter the atmosphere when your missile will even travel 200 kms..


GUESS when someone is lauching a BM...

I agree that in future BMs will be intercepted with more accuracy but it will only increase the BM technology evolution and will create more threat than the ABM systems will be able to handle.

I would not like to carry this childish discussion.
You called the pakistani missiles as rain, I gave a suitable reply.
At the end of the day, we have something that can stop
missiles from inflicting any damage to the people of our country. Period.

Excellent news, this is result of years of hard work in some of the complex technologies and that's what finally paid off. It is most interesting to feel that within very short span of time, DRDO has been coming up with some of the cutting edge missile technologies. Now this particuler news has raise my confindence in DRDO by 400%. DRDO, you have made my day.

Ashwin: New Surface-to-Surface Missile In The Offing?




Dated 12/12/2007

Two successful interceptor missile tests carried out by Indian scientists as part of the country's ballistic missile defence program in the first week of December has led to development of a new surface-to-surface missile that could be possibly named as 'Ashvin'.

The endo-atmospheric interceptor missile AAD, the missile used to engage the approaching 'enemy' missile at a height of around 15 kms from the surface of the earth could be used as a surface-to-surface missile in the days ahead.

The AAD, which is 7.5 mts long and has a solid rocket propeller with siliconised carbon jet vanes, has a range of over 150 kms and could achieve a maximum velocity of 1400 m/s.

The USP of this AAD is its high precision INS system, faster on board computer with advanced technologies like RF seeker, agility and the capability to launch the missile in any direction in autonomous mode.

The December tests have validated that the AAD could also be used as an Extended Range Surface-to-Air Missile, beside being used as a ballistic missile interceptor.

Dr V K Saraswat, who is the team leader of the ballistic defence programme, was also involved with the development of the India's first surface-to-surface missile Prithvi I and Pritnvi II (Dhanush).

"The AAD could be used to target aircraft," Dr. Saraswat said, adding that its successful launch has opened up a 'new era' with the development of supersonic interceptor missiles that can be used for defence against Cruise missiles.

He said that the AAD part of the missile defence programme is completely independent from surface-to-surface missile programme and that it is purely a spin off of the entire project.

Prithvi I is India's first indigenously developed tactical surface-to-surface short-range ballistic missile (SRBM) developed under the Integrated Guided Missile Development Program and has already been inducted into the Army.

The single stage liquid-fuelled Prithvi I with maximum warhead mounting capability of 1000 kg has a range of 150 km. It has an accuracy of 10- 50 metres, while the AAD is precise to 0.5 mts.

Prithvi II (Dhanush) is the Air Force version of 250 kms range and capacity to carry a payload of 500kg, while Prithvi III is the naval version of 350 km range with a payload of 500 kgs.

Defending the idea of having a ballistic defence program, Dr. Saraswat said that threats of ballistic missile exists along with the proliferation of these threats, and added since India has a no first use policy, it becomes inevitable to protect the country from any future missile attack.

"The program shows the defensive position of the country and not an offensive position," he added.

India develops missile shield, can protect two cities
India has developed missile defence shield which can be put in place at short notice to protect at least two cities, bringing the country on par with an elite group of few nations.

The shield, developed by DRDO, has been tested successfully and an incoming ballistic missile with
the range of up to 2,000 kms can be destroyed. The system is to be upgraded to the range of 5,000 kms by 2016.

"The Ballistic Missile Defence shield is now mature...We are ready to put phase one in place and it can be put in very short time," DRDO chief VK Saraswat told PTI in an interview.

He said the shield, as part of phase one of the programme, can be put in place at two places in the country, where the infrastructure is available.

However, the two places have not yet been identified and the selection will be made at the political level.

The DRDO used variants of Prithvi missiles as simulated targets and successfully intercepted missiles in test-firings.

"We have carried out six successful launches and demonstrated the capability for 2,000 km targets...We have demonstrated it in two layers that is endo-atmospheric (inside the Earth's atmosphere) and exo-atmospheric (outside the Earth's atmosphere)," Saraswat said.

He said all the elements such as long-range radars and tracking devices, real-time datalink and mission control system required for the missile system have been "realised" successfully.

Under the phase two of the project, the premier defence research agency would upgrade the system to handle ballistic missiles with range of 5,000 km. This phase is expected to be ready by 2016.

The system required for phase-II of the project is being developed, he said, adding that for this purpose, ships are being built from where the target missiles would be launched.

The DRDO chief said the phase two of the project is expected to be completed by 2016.

Talking about the advancement of the system, Saraswat said the missile defence shield has been "automated" to an extent where human intervention would be required only if the mission has to be aborted.

The DRDO chief said the Indian missile defence system is comparable with the US Patriot 3 system, which was successfully used during the 1990 Gulf War against Iraq.

As part of its efforts to protect itself from enemy missiles, India is developing this two-tier BMD which can intercept enemy missiles at altitudes of 80 km and 150 km.

The DRDO is thinking of intercepting the missiles at higher altitudes as it would give it more response time in case the first attempt is a miss and the second layer of the system can be put into action.

The system was first test-fired in November 2006 elevating India into the elite club of countries to have successfully developed an Anti-ballistic missile system, after United States, Russia and Israel.

Pakistan needs to counter this

 

[parkland]

this is just the baby defence. this year we will see pdv killing a missile at 150 km and ad1 and ad 2 at 250 km. and then will come midcourse and asat. great going india.

 

[AUSTERLITZ]

Same thread on indian def.

 

[and 3 others]

this is the field we should master and have to master jhakk maar k, a lot depends on these shields of how much of India will be left after a possible ww3. even an achievement of 80% is a great success and the scientists confirmed that it takes two AAD and 2 PAD to intercept incoming missiles with 99.5% accuracy its expensive but definitely worth it.

 

[jawaddar]

Don't you think that missile defence shield can be saturated by firing more missiles to the same target.

 

[Jackdaws]

Instead of wasting dough on white elephants; India should hire more cops and try and solve crime within city limits. No one is launching ballistic missiles.
