Pune Based DRDO Lab Makes Most Powerful Conventional Explosive

http://pib.nic.in/release/release.asp?relid=67872

Move over RDX! That's passé for the needs of the Indian Armed Forces. The DRDO is developing a powerful explosive, - the CL-20, that can substantially reduce the weight and size of the warhead while packing much more punch. In fact, the RDX is not the standard explosive in use with the Indian Armed Forces; the warheads are mostly packed with HMX, FOX-7 or amorphous Boron.

Scientists at the Pune-based High Energy Materials Research Laboratory (HEMRL) have already synthesized adequate quantity of CL-20 in the laboratory. "It is the most powerful non-nuclear explosive yet known to man," says Dr. AK Sikder, Joint Director, HEMRL, who heads the High Energy Materials Division. The compound, 'Indian CL-20' or ICL-20, was indigenously synthesized in the HEMRL laboratory using inverse technology, he added. "The HEMRL has taken India to an elite club of countries with advanced capabilities in the field of Energetic Materials," said Shri Manish Bhardwaj, a senior Scientist with the HEMRL. In fact, the CL-20 is such a fascination for the HEMRL that a larger-than-life size model of the compound occupies the pride of place as one enters the portals of the main building of the DRDO's premier lab in Pune.

CL-20, so named after the China Lake facility of the Naval Air Weapons Station in California, US, was first synthesized by Dr. Arnold Nielson in 1987. CL-20, or Octa-Nitro-Cubane, is a Nitramine class of explosive 15 times as powerful as HMX, His/Her Majesty Explosive or High Melting Explosive or Octogen. The HMX itself is more than four times as potent as the Research Developed Explosive or Royal Demolition Explosive or Cyclonite or Hexogen, commonly known as RDX.

"CL-20 offers the only option within the next 10-15 years to meet the requirements of the Indian Armed Forces for Futuristic Weapons," said Dr. Sikder. "CL-20 -based Shaped Charges significantly improve the penetration over armours," he said, adding that it could be used in the bomb for the 120-mm main gun mounted on the MBT-Arjun. "But the costs of mass production of ICL-20 are still prohibitive," said Dr. Sikder. Compared to Rs.750 per kilogram it takes to produce RDX in the factory today, the HMX is worth about Rs.6,000 per kg while a kilogram of CL-20 costs a whopping Rs.70,000 per kg.

"We have a tie up with industry partner for intermediate commercial exploitation of ICL-20," said Dr. A. Subhananda Rao, Director, HEMRL. About 100 kgs of ICL-20 has been produced by HEMRL in collaboration with the Premier Explosives Limited (PEL). The CL-20, which looks like limestone or grainy talcum powder, is being manufactured by the PEL factory at Peddakanlukur village in Nalgonda district of Andhra Pradesh. The Rs.60 crores Hyderabad-based company bagged the DRDO's Defence Technology Absorption Award, 2007 worth Rs.Ten Lakhs, presented by Prime Minister Dr. Manmohan Singh on May 12, 2008, their most prestigious award, claimed company sources.

"The advantage with the CL-20 is its Reduced Sensitivity," said Dr. Sikder, enabling easy handling and transportation of the lethal weaponry. In fact, the HEMRL is concentrating on the Reduced Shock Sensitivity (RSS) explosives, such as RSS-RDX, which costs about Rs.1,500-2,000 per kg, and RSS-HMX. "There is a whole array of low sensitivity material or Insensitive Munitions we are working on," said Dr. Rao. "The world around there is a lot of R&D being pumped into what are called the Green Explosives, as also the advanced Insensitive Munitions (IM) and RSS explosives," added Dr. Sikder, which reduces the chances of mishap and loss to M4, - Men, Money, Materials and Machines.

Push for artillery modernisation, OFB proposes Bofors upgrade

Tehelka - India's Independent Weekly News Magazine


The Indian Army's artillery modernisation programme got a push forward as the Ordnance Factory Board (OFB) has proposed to indigenously upgrade the 155 mm FH 77B Bofors gun purchased 24 years ago.

The Bofors artillery guns, which helped India in the Kargil conflict of 2000, have been awaiting the upgradation for over 10 years now. Since 1995 the army has been planning to upgrade the 410 guns, purchased in 1986 from the now-defunct Swedish firm AB Bofors. The upgraded versions will have a better range.

"The government has received a proposal from the OFB to undertake upgradation of the 155mm Bofors guns"¦ OFB submitted a bid, which is under evaluation at the Ministry of Defence," said Minister of State for Defence MM Pallam Raju in the Lok Sabha on Monday.

In 2008, the Defence Ministry had invited proposals for the upgradation of the FH 77B guns from 39 calibre to 45 calibre. However the upgrade was delayed after being hit by a string of corruption scandals. Almost a year after its purchase, Bofors ran into what is now considered a historic controversy with alleged involvement of middlemen. Since then, the company has been blacklisted, and the deal looked at with suspicion.

"The blacklisting has delayed the upgradation as the OEM (original equipment manufacturer) Bofors (now owned by British BAE Systems) could not be asked for the the same," said an Indian Army official, requesting anonymity because he is not authorised to speak to the media.

The Indian Army's artillery modernisation programme has repeatedly been mired in controversies with gun majors coming under the scanner for corruption.

In 2009, Singapore Technologies Kinetics was selected for field trials of ultra-light howitzers after 10 months of evaluation, which would help the army counter the Chinese threat in the mountainous Himalayan region. However, the firm was blacklisted after its name figured in a corruption case investigated by the Central Bureau of Investigation (CBI).

Following the scam, the government cancelled the trials in the Rs 2,900 crore order for 140 ultra-light howitzers. The army is now purchasing the guns from the US through direct sales.

The Singaporean firm was also a contender for the Rs 8,000 crore order for 400 units of the 155 mm/52-calibre towed artillery guns, as well as the indigenous manufacture of another 1,100 howitzers through transfer of technology. However, by 2004, after multiple firing trials, India's towed artillery competition managed to end up without any competitors left standing. All three platforms -- Bofors FH-77 B05, Soltam TIG 2002 and Denel G5/2000 -- failed to meet India's accuracy specifications for the 2003 trials, but all three improved their guns to compete again in 2004. Reports say that Soltam fell out of the race after its barrel burst during field trials, while South Africa's Denel was sidelined in 2004 and then eliminated in 2005, after the Indian government accused the manufacturer of corruption in another defence deal.

I'd like some more info on this CL-20. What is its small volume expansion? What is its sensitivity? What is its oxidizer-fuel ratio? And what are the potential capabilities of using this in weapons systems?

Here's something I found on another website for CL-20- apparently, it's not just an explosive, it's an ingredient in solid, smokeless rocket propellants as well.

One of the most active areas of solid propellant research is the development of high-energy, minimum-signature propellant using CL-20 (China Lake compound #20), C6H6N6(NO2)6, which has 14% higher energy per mass and 20% higher energy density than HMX. The CL-20 is non-polluting: acid free, solid particulates free, and lead free. It is also smoke free and has only a faint shock diamond pattern that is visible in the otherwise transparent exhaust. Without the bright flame and dense smoke trail produced by the burning of aluminized fuels, these smokeless CL-20 all but eliminate the risk of giving away the positions from which the missiles are fired. The CL-20 based propellant is shock-insensitive (hazard class 1.3) as opposed to current HMX smokeless propellants which are highly detonable (hazard class 1.1). CL-20 is considered a breakthrough in solid rocket propellant technology but has yet to see widespread use.

DRDO to Develop New Generation EW System


India Defence Online, New Delhi — India will soon have its very own radar-based electronic warfare system (EWS) to enable the Armed Forces with a decisive edge in futuristic warfare. The State-owned Defence Research and Development Organisation (DRDO) has initiated the development of the radar based EWS which will be ready by 2013.

According to the DRDO, the radar-based EWS will be ready in three years along with test-ranges in the Indian states of Karnataka and Andhra Pradesh.

The cost of each testing range is roughly $45 million. As for the EWS systems, they would use electromagnetic spectrum for attack, protection and warfare support to destroy the combat capabilities of the enemy. Currently, a prototype EWS has been integrated with MiG-27 fighter for test flight. According to the plan, the EWS will be integrated with MiG-29, Jaguar, Sukhoi-MKI-30 of the Indian Air Force (IAF) and the indigenous Light Combat Aircraft (LCA) Tejas by 2011.

As for the testing ranges being envisaged by the DRDO for the EWS, the Chitradurga aeronautical test range at the DRDO's 4,000-acre campus in Karnataka and will be used for communication-based EWS. As for the non-communication EWS, the Tandur range in Andhra Pradesh will be used. These testing ranges will be operational by 2012.

Speaking at a conference, DRDO Chief Controller Dr.Prahlada said that the main aim is to develop the fourth-generation EWS by 2012. He added that the need for EWS is imperative in a modern era of warfare. The fourth-generation EWS is being developed by the state-run Defence Avionics Research Establishment (DARE) and Defence Electronics Research Laboratory (DERL).

DRDO working on New rocket system for coastal Security

BY: PTI

The DRDO is currently testing a new short-range coastal security rocket system for deployment on shore and on board ships to target rogue boats such as those used by terrorists to carry out the Mumbai attacks.

The DRDO's Chandipur-based Proof and Experimental Establishment (PXE) is testing the 4-km range 140mm rockets that can accurately target the smaller boats and sink them, according to S Sundaresh, Chief Controller of Research and Development (Armament and Combat Engineering) of the premier defence research agency.

Developed in collaboration with the Ordnance Factory Board (OFB) and Navy's Directorate General of Naval Armament and Inspection, the rockets' development and likely production are being fast-tracked following the 26/11 terror strikes, he said.

PXE Director Major General P Mathur said the coastal security weapon comes with a launcher and 12 rockets that can be fired simultaneously to rain the warhead over the intended target.

"This is cost-effective weapon system. But it is now in the developmental stage. OFB is the production agency," Mathur said.

The remote operated rocket system is an indigenous development that emerged out of the confluence of the minds from the OFB, DRDO and the Navy, who would be the users of the weapon.

"It has been proposed to deploy these rockets all along the 7,516-km-long coastline of ours including the island territories. We expect the weapon system to go into production within months from now," a Navy officer associated with the project said.

"Apart from being deployed on the shore, the rocket system can be mounted on ships too," he added.

To acquire targets, the user will have to visually identify the rogue or enemy boats and then use his remote control to fire the rocket barrage on them.

Though the three defence agencies were already working on the rocket system project even before the 26/11 attack, the weapon has now become "a hot property" and there is a sense of urgency to get it operational, Navy officials added.

Forces to get most potent non-nuke bomb yet

NEW DELHI: Indian armed forces may soon have the most powerful non-nuclear explosive, CL-20, which is 15 times as powerful as HMX or Octogen. HMX itself is four times as potent as RDX — the explosive often used by terrorists to unleash mayhem. The High Energy Materials Research Lab (HEMRL) of DRDO in Pune is developing the nitroamine explosive CL-20, which takes its name from the China Lake facility in California, where it was first synthesised in 1987. The Indian version of the explosive is called ICL-20.

"We have already synthesised adequate quantity of ICL-20 in the lab. CL-20 offers the best option to meet the requirements of armed forces for futuristic weapons within next 10-15 years," said A K Sikder, joint director of HEMRL.

Lab director A Subhananda Rao said, "We have a tie-up with an industry partner for commercial exploitation of ICL-20." So far, around 100 kg of ICL-20 has been produced by HEMRL in collaboration with Premier Explosives Ltd (PEL) at the latter's factory at Peddakanlukur in Andhra Pradesh's Nalgonda district.

ICL-20 can be used to substantially reduce the size and weight of the warhead on a missile, bomb or some other delivery system. "The advantage of CL-20 is its reduced sensitivity," said Sikder, which enables "easy handling and transportation of lethal weaponry"

CL-20 will significantly improve penetration and could be used in bombs for the 120-mm main gun mounted on indigenous main battle tank Arjun.

Sikder said while the manufacturing cost of RDX was Rs750/kg and that of HMX about Rs6,000/kg, a kg of CL-20 would cost a whopping Rs70,000 to make. The explosive looks like limestone or grainy talcum powder and has the advantage of reduced sensitivity, which would enable easy handling, transportation and air dropping.

India's Defence Information and Communications Projects Closed to Foreign Vendors
Def-Com-2010




International vendors will be kept out the defence information, communication technology (ICT) and net centric project areas in India as the government would like to keep this sector exclusively for Indian companies.


Going by the observation of Indian minister of state for defence, Mr. Pallam Raju at the DEFCOM 2010 conference in New Delhi, it appears that projects in the information and communications sector will be given to Indian public and private companies only. The minister noted, "there should be no requirement of looking over our shoulders to foreign OEMs and technology providers (in the defence ICT sphere). Our industry is mature enough to take on this task with indigenous resources & efforts. I am sure that our industry will be able to take this challenge which will be very assuring to the Armed Forces in their endeavour for modernization".

An endeavour has to be made by Indian Industry to focus on core technologies and be geared up to provide life time support to equipment and upgradation of technologies, he said.

The Indian Industry has productionised quality equipment and security procedures of international standards which qualify them for assuming greater responsibility in defence production. In order to synergise and enhance the national competence in producing globally competitive defence equipment without time and cost over-runs, the government is exploring all viable initiatives such as formation of consortia, joint ventures and public-private partnerships.

The Defence Procurement Procedures are evolving and a definite role for the Indian Industry in Defence Procurement is emerging concurrently with the role of Defence Public Sector Undertakings (DPSUs).

The Tactical Communication System project of the Indian Army is well on the way after some initial delays. This project provides the Indian Industry an excellent opportunity to seek its share of defence production, the Minister added.

BEML exploring foray into helicopter, small aircraft assembly

BANGALORE: Public Sector Undertaking BEML is exploring the possibility of venturing into the business of assembly of helicopters and small aircraft.

"When you are in aerospace (business), it (assembly of helicopters and small aircraft) can't be out of your radar," Chairman and Managing Director of the Bangalore-headquartered Mini-Ratna company under the Ministry of Defence V R S Natarajan said.

"We are looking at the possibility," he said. BEML Ltd has made a set of landing gears for helicopters of Hindustan Aeronautics Limited and expecting orders, he said, adding, the company is already supplying some body parts of fighter aircraft.

BEML is now setting up a facility for fabricating titanium metal, aluminium and composites - things used in manufacture of helicopters.

To start with, the company is seeking to position itself as a "single-point" for products for ground-support, and those related to hydraulics, lift and ladder and also strengthen its business of manufacturing of aero-plane parts.

If indeed BEML finally decides to assemble helicopters and small aircraft, it could be sometime during 2011-12 to 2016-17 timeframe.

Natarajan said it's too premature to discuss this initiative as the proposal is only being explored now but he was clear that he saw assembly of helicopters and small aircraft a logical step forward for BEML.

"Ultimate objective is to move towards that only," he said.

He said the BEML has acquired 25-acres in a special economic zone at Devenahally on Bangalore outskirts, where it would design, manufacture and roll out aero and space products.

Aerospace products business is expected to contribute close to Rs ten crore to the overall turnover of BEML in the current financial year but in the next three years, this segment is projected to grow to Rs 100 crore.

The company is also in discussion with Indian Space Research Organisation for supplying components for its space programmes.

BSNL seeks 5k cr more to build defence network

NEW DELHI: BSNL has overshot its budget for building an alternate communication networks for the armed forces by a huge 50% and will soon seek an additional funding of Rs 5,354.55 crore from the Centre, executives familiar with the development told ET.

This is in addition to the Rs 9,175.16 crore that the company has already been awarded fr this project. The telecom ministry within the next couple of days will move a cabinet note seeking a 50% hike in the budget for this project, executives linked with the project added. In December 2009, the Union Cabinet, had approved the Rs 9,175-crore plan to build an alternate optic fibre cable (OFC) network for the defence services paving the way for the auction of third generation spectrum to be held this year. BSNL has not provided any explanation so far for overshooting its budget.

The armed forces will move their communication requirements to this network to be built by BSNL, thus freeing airwaves for commercial telephony Rs The armed forces had vacated 3G frequencies in August 2010 after it they had been assured by the Centre that the telecoms department would keep its side of the bargain in rolling out this alternate network as scheduled.

This enabled the telecoms department to allot 3G bandwidth to the winners of the auction on Sept 1, paving the way for consumers to enjoy high-end services such as video calling, interactive gaming and high-speed internet using phones by the end of the calendar year. MP Birla Group company Vindhya Telelink had earlier this year bagged a Rs 7,582-cr contract from BSNL to build an OFC network for the armed forces.

CVRDE to make gearbox for aircraft

CHENNAI: The Combat Vehicles Research and Development Establishment (CVRDE) has been entrusted with the task of developing gearbox for the Advanced Medium Combat Aircraft (AMCA), a fifth generation aircraft, P Sivakumar, CVRDE director, said here on Wednesday.


He added that the Aircraft Mounted Accessory Gearbox (AMAGB), developed by CVRDE for Light Combat Aircraft, Tejas, has received the "type approval" from the Centre for Military Airworthiness and Certification (CEMILAC).

The approval certificate was handed over by K Tamilmani, chief executive of CEILAC, to Sivakumar on December 4.

Sivakumar said Indian Navy has approached the CVRDE for gearboxes for its submarines, being developed indigenously.

AMCA is an ambitious project to indigenously design and develop a fifth generation aircraft undertaken by Aeronautical Development Agency (ADA) in Bangalore. It is expected to be readied by 2017.

Giving details about the AMAGB, CVRDE scientists Chandrasekaran and Ganesan said the AMAGB is critical Line Replacement Unit (LRU) for the LCA, Tejas, and forms a very important part of Secondary Power System.

The gearbox casings are made of magnesium alloy and weighs 38 kg. It has a maximum power transmission capability of 185 kW at a rated speed of 16810 rpm.

The AMAGB operates in two modes - starter mode and accessory mode. In starter mode, it aids in starting the engine through Jet Fuel Starter (JFS) whereas in accessory mode, it drives accessories, namely, two hydraulic pumps and an Integrated Drive Generator (IDG). These accessories in turn generate hydraulic and electrical power required for the aircraft.

On why it took 17 years to develop the engine, Sivakumar said the work was started in 1993 and the gearbox was ready by 1999 and was certified for use in aircraft the same year.

Further tests were held after this, he added.
