 DRDO’s Chandigarh lab to develop advanced e-fuses for munitions

Chandigarh, October 27
In a radical departure from conventional mechanical fuses for various kinds of service ordnance and warheads, the Defence Research and Development Organisation (DRDO) is developing advanced electronic fuses for enhancing the lethality, safety, commonality and reliability of munitions.

The fuse is a very critical sub-system of ammunition and warheads which make them function at the right place and at the right time after launch. At the same time, it keeps them safe while in storage, handling or transportation.

Conventional fuses are mostly mechanical and pyrotechnic-based and their designs are based on chemical delays. Primary explosive-based initiators have inherent issues of inconsistency and safety due to their high sensitivity to heat, shock, friction and humidity and are susceptible to ageing. Consequently, there are associated reliability and safety issues. Moreover, conventional fuses are heavy, bigger in size and costly.

Advanced electronic fuses based on highly accurate and precise electronic timers and micro-electro-mechanical system (MEMS)-based sensors and initiators will not only enhance safety, accuracy and reliability but also be cheaper than their older-generation counterparts.

It is estimated that about five million such fuses will be required in the next five years by the Indian armed forces.

The project is being undertaken by DRDO’s Terminal Ballistics Research Laboratory (TBRL) at Chandigarh in collaboration with academia and industries.

TBRL Director Dr Manjit Singh said that the project is highly challenging in which many critical technologies like shock-mitigating materials, MEMS sensors capable of sustaining hyper acceleration, mini and micro detonators, secondary explosive-based initiators, ultra high energy density power sources etc would have to be developed in the next two to three years.

A comprehensive roadmap to achieve the goals in the given time frame has been chalked out and a dedicated team of about 20 scientists is working exclusively on this programme under project director Pravendra Kumar.

Dr Manjit Singh added that the adoption of these new technologies would not only enhance the safety but also increase the reliability due to reduction in the number of moving parts required for arming the fuse.

Why the change

    Conventional fuses are mostly mechanical and pyrotechnic-based and their designs are based on chemical delays
    Primary explosive-based initiators have inherent issues of inconsistency and safety due to their high sensitivity to heat, shock, friction and humidity. These are susceptible to ageing
    Conventional fuses are heavy, bigger in size and costly
Lull at border, but J-K villagers look for contingency plans

Jammu/Rajpura, October 27
The guns have fallen silent. “Really?” asks Sewa Ram staring vacuously in the Lalyal Camp in Kanachak sector, barely 8km from border with Pakistan. A two-day lull in heavy firing has made him even bitter: what will happen to his paddy crop? And will he get enough food for his family?

The respite from firing, apparently a result of back-channel diplomacy between India and Pakistan, is showing the cracks in the contingency plans meant for border villages.

Ever since Sewa Ram’s family was shifted along with scores of others to the Camp after the 1971 war, he has seen only worse. “We were in the Chhamb area in Pakistan then. After some agreement between the two sides, we were taken to Lalyal Camp. Indian troops never fired on us when we were on the other side. And now, we seem to be nowhere men,” says Sewa Ram. He is one of the over 40,000 villagers who live close to the 198-km long International Border alone from Kathua district to Akhnoor sub-division in Jammu district. According to the administration, around 300 villages are located close to the Zero Line from Kathua to Poonch district

Over the years these villagers have had only assurances of “contingency plans” that the government has announced for the border villages in case the border skirmishes get too hot. “We manage everything on our own when Pakistani troops fire mortars. We have not been able to harvest our paddy crop and our children are facing starvations while this government is making tall claims,” he says.

Villagers in Balakote, Drati, Ramlutta, Swala, Deri, Dabbi, Basooni, Goulad, Tain, uppar Chajala and Sabra Gali say they have been facing hardships since August, but the district administration has remained a mute spectator.

Rangers use heavy weapons

Jammu: Pakistani forces have fired 82 mm mortars on hapless villagers. These mortars with a range of 5 km cause widespread damage. Villagers, including children in Suchetgarh Kulian in Samba and RS Pura sectors, have borne the brunt of firing since October 17. “In total violation of Geneva conventions, the Pak Rangers have used 82 mm mortars, 60 mm mortars and heavy machinegun fire on forward Indian villages”, said a senior BSF officer. He said the BSF has used similar weapons only at military targets.

Amid bullets, the flower power

Rajpura: Amid flying bullets and mortar fire, the sight of marigolds surprises you. Grown by a graduate farmer and his family in Garkhal, a village that sits on Zero Line in the Akhnoor sector, these flowers will show you how passion for something you love can overcome fears of a surrounding strife. “Mortars do fall in my farmland,” says Kewal Krishan Sharma, 51. Despite bullets flying over our heads, I and my family take immense pleasure in cultivating marigolds,” says Sharma.

Congo army says it captured rebel stronghold; peacekeeper killed

(Reuters) - Government forces said they captured the rebel stronghold of Rutshuru on Sunday in a third day of fierce fighting in eastern Democratic Republic of Congo in which one U.N. peacekeeper was killed and another injured.

Following two months of relative calm in the region, fighting flared on Friday after peace talks in neighbouring Uganda broke down when M23 rebels demanded a full amnesty for their leaders. President Joseph Kabila last week ruled out a blanket pardon.
Three days of victories by government forces have raised the prospect that the army could defeat Congo's most important rebel group, ending a 20-month uprising which has displaced tens of thousands of people.

Army spokesman Colonel Olivier Hamuli told U.N. radio Okapi on Sunday that government forces had recaptured Rutshuru, some 70 km (43 miles) north of Goma, the largest city in eastern Congo. Rutshuru had been taken by the rebels just over a year ago and was serving as a regional base.

The army, which is attacking the rebel enclave in north Kivu province from the north and south, took the town of Kiwanja earlier on Sunday, a day after wresting the strategic outpost of Kibumba on the Rwandan border.

"We are consolidating the zones we have conquered," Hamuli had earlier told Reuters. He refused to discuss rebel requests for a return to peace talks in Kampala, saying: "We will continue to do our jobs as soldiers."

M23 said in a statement on Sunday it had withdrawn its troops from Kiwanja, accusing the army of sending in fighters in civilian clothing to try to draw U.N. troops into the conflict.

M23 threatened to withdraw its delegation from the stalled peace talks in Kampala unless there was an immediate end to hostilities. It said it would then launch a large-scale counter-offensive.

The U.N. mission in Congo (MONUSCO) said the Tanzanian peacekeeper was killed during fighting with M23 in Kiwanja.

"The soldier died while protecting the people of Kiwanja," Martin Kobler, the head of MONUSCO, said in a statement. The previous round of clashes between the army and rebels in late August killed at least two Tanzanian peacekeepers.


Rwanda, which denies U.N. experts' allegations that it supports the rebels, said on Friday that Congolese army shells had landed in its territory, raising fears of a regional conflict.

Congo's army, supported by a new U.N. intervention brigade, scored its first victories against the rebel movement, which has been fighting for nearly two years, in late August, forcing the rebels away from Goma.

The U.N. brigade has a tough new mandate to eliminate armed groups in the eastern provinces, though it has not been involved in the past three days of fighting.

The support of the brigade and the weakening of the rebels has fuelled belief that Congo's army - notoriously disorganised, undisciplined and under-supplied - could defeat M23.

Army sources told Reuters reporters in Goma that M23 had been weakened by desertions, with some 40 rebels taking advantage of a corridor created by the government troops to allow then to flee rebel lines.

M23 began in early 2012 as a mutiny by soldiers demanding the government implement the terms of a 2009 peace deal signed with a previous Rwanda-backed rebel group, many of whose members had been integrated into the army.

Army spokesman Hamuli said some M23 fighters had fled towards the Rwandan border in the face of the army advance.

"There are small pockets of M23 resistance in the hills near Rwanda," he said. "We think Rwanda has to prove its good faith and oblige M23 to disarm, or disarm them itself."
