Chandigarh, May 28
Moving on the ground at velocity equal to three times the speed of sound sounds incredible, but this is just what the Terminal Ballistics Research Laboratory (TBRL) in Chandigarh has achieved.

Referred to as the Rail Track Rocket Sled (RTRS), the facility is designed to evaluate the design and ballistic parameters of aerospace components, including warheads and nose cones of missiles, simulate missile interception, analyse the performance of munitions and test structural integrity.

The facility, recently upgraded at a cost of about Rs 100 crore, consists of a 4 km-long track comprising five parallel precision-laid seamless rails giving widths of different gauges. Aerodynamic sledges made of aluminum and powered by rockets or jet engines are used as test beds on which the components to be tested are mounted. The rails can withstand a load of 10 tonne.

“The length of the rail track has been increased from 2 to 4 km and the speed limits enhanced from 1,800 kmph to 3,600 kmph, which is about Mach 3. Where simulation of missile interception involving an incoming enemy missile and a killer missile is concerned, the relative velocity can be as high as Mach 5,” Dr PK Khosla, group head at the TBRL said.

“With the RTRS, we can evaluate some parameters which are not possible with static or actual airborne trials because in that case the projectile disintegrates or is non recoverable,” he added.

For example, while testing a particular type of bomb on RTRS recently, it was found that it was an imperfect crew that was resulting in deviations. In actual trails, it would not have been possible to detect the errant screw. TBRL Director Dr Manjit Singh said: “The facility is based on the concept of Captive Flight Testing, which affords us the recovery of the tested items for their post test analysis. Besides missile components and bombs, RTRS will be useful in testing advanced fuses, parachutes and unmanned aerial vehicles, etc.”

 INS Vikrant moved to scrapyard
Tribune News Service

Mumbai, May 28
Indian Museum Ship Vikrant, the country’s first aircraft carrier decommissioned and turned into a floating museum before being destined for the scrapyard, was moved to a ship-breaking yard today, according to naval officials here.

A tugboat towed Vikrant away from the naval docks at 9.45 am and relocated it at the ship-breaking yard off South Mumbai a few hours later. The ship has been sold to a private company, IB Commercial Private Ltd, for Rs 60 cr which will break the ship for scrap. The Supreme Court is hearing a petition against the disposal of Vikrant as scrap.

The proposal to sell of Vikrant as scrap has come in for severe criticism. The Shiv Sena and BJP are demanding that the Maharashtra Government find the funds to turn Vikrant into a maritime museum.
Army holds first-ever conclave on leadership

The first-ever Army Commanders’ Conclave at the Shimla-based Army Training Command (ARTRAC) saw several former heads of the command get together earlier this month for a five-day brainstorming session on military leadership and the prerequisite for future military commanders.

Two former Army Chiefs, General JJ Singh and General Deepak Kapoor, who had earlier headed the ARTRAC, along with Lieutenant Generals AS Kalkat, the command’s founding GOC-in-C, SK Sharma, Vijay Oberoi, HB Kala, K Nagaraj, KS Jamwal, ML Naidu, BS Jaswal, AS Lamba and the incumbent GOC-in-C, Lt Gen Sanjeev Madhok were among a host of senior officers who attended the event. During the conclave, a number of pertinent issues, especially on training and leadership, were discussed. These will be further analysed and deliberated upon for inclusion in the training curriculum based on their merit. The conclave gave an opportunity to tap the wealth of knowledge, wisdom and experience of the old guard and given the rapid societal, technological and institutional transformations, review training methods will enable the Army to institute mechanisms for further refinement of leadership development.

Lt Gen Hooda to head Northern Command

Lt Gen Deependra Singh Hooda will assume charge as the General Officer Commanding-in-Chief, Northern Command at Udhampur, on June 1. He will take over from Lt Gen Sanjiv Chachra who will hang up his boots by the end of this month. Commissioned in 4/4 Gorkha Rifles, Lt Gen Hood had earlier served as the GOC 16 Corps at Nagrota which is part of the same Command. Highly experienced in counter insurgency operations, he had commanded 57 Mountain Division in the east and also served as the Chief logistics officer of the United Nations Mission in Asmara (Ethiopia). He is an alumnus of the Canadian Forces Command and Staff College.

COAS and Gorkha link

When Lt Gen Dalbir Singh Suhag takes over as the Chief of Army Staff (COAS) on August 1, he would be the first officer to have been commissioned into a Gorkha Regiment to hold the Army’s top appointment. Lt Gen Dalbir Singh, currently the Vice Chief of Army Staff, was commissioned into the Fourth Battalion of the Fifth Gorkha Rifles in 1974. In the Army’s history, two chiefs, Sam Manekshaw (1969-73) and Gen GG Bewoor (1973-75), have been associated with the Gorkha Brigade, but both were commissioned in other regiments pre-Independence.

Featherweights turn 28

The IAF’s only heavy lift helicopter outfit, 126 Helicopter Flight, turned 28 this month. The unit, known as the Featherweights, was raised at Chandigarh on May 15, 1986. Equipped with the Soviet-origin Mi-26, the world’s largest helicopter, the unit has been undertaking regular sorties to the northern sector to airlift vital equipment, vehicles, artillery guns and earth moving equipment in support of military operations.

Akash supersonic missiles test-fired successfully

Balasore (Odisha), May 28
The Defence Research and Development Organisation (DRDO) today successfully test-fired the Akash air defence missiles off the coast of Balasore in Odisha.

Three Akash missiles were launched from the Integrated Test Range (ITR) at Chandipur, on tow body target of Lakshya pilotless target aircraft moving at "low altitude for boundary" and ripple mode missions.

"The missiles intercepted the fast moving and manoeuvring small RCS (radar cross section) targets within small interval of five seconds in ripple mode," said Ravi Kumar Gupta, Director, Directorate of Public Interface, DRDO.

Indian Air Force Test Fires Akash Missile in Ripple Mode

BALASORE (ODISHA): Indian Air Force (IAF) personnel for the first time successfully test fired surface-to-air nuclear capable supersonic missile Akash in ripple mode from the Integrated Test Range (ITR) off the Odisha coast on Wednesday.

Defence sources said three Akash missiles were launched from the test range at Chandipur on tow body released from Lakshya pilot-less target aircraft (PTA) moving at ‘low altitude far boundary’. The missiles successfully intercepted the fast moving and maneuvering small targets within small interval of five seconds in ripple mode.

While the DRDO provided all logistic supports, IAF teams operated the deliverable Akash missile system including targets. The missiles were successfully guided by multi-function phased array radar developed by Electronics and Radar Development Establishment (LRDE), a DRDO Lab and produced by Bharat Electronics Limited (BEL).

Akash is a medium-range surface-to-air missile and it can reach targets 25 km away. The 5.8-metre-long sleek missile has a launch weight of 720 kg and can carry a warhead of 50 kg. It is a mobile multi-directional, multi-target point / area defence system which can simultaneously engage several air targets in a fully autonomous mode of operation.

The hardware and software integration of the weapon system elements permits automated management of air defence functions such as programmable surveillance, target detection, target acquisition, tracking, identification, threat evaluation, prioritization, assignment and engagement.

 A defence official said all the radars, command control centers and launchers are integrated to achieve these  functionalities. The system is designed to enable integration with other air defence command and control networks through secure communication links. The system is also provided with advanced features at various levels.

The missile has been developed by Defence Research and Development Laboratory (DRDL) along with 13 other DRDO Laboratories and produced by Bharat Dynamics Limited. Its launcher is developed by R&DE (Engrs), a DRDO lab and produced by Tata Power and L&T.

Scientific Advisor to Raksha Mantri (SA to RM) Avinash Chander congratulated all the teams from DRDO, production agencies and IAF for successfully organizing the event and fulfilling the mission objectives of the evaluation tests on deliverable equipment.

He also stated that various industries across the country were engaged in production of Akash subsystems of military grade/aerospace quality systems and had emerged successfully in meeting the stringent requirements.

Two squadrons of Akash missile system have been already inducted in to IAF and the system is in continuous production and induction. IAF had placed order for eight squadrons of Akash missile system. Later, Indian Army placed an order for two regiments of Akash missile system.

The total production orders placed by both the services (IAF and Indian Army) for Akash missile system approximately amounts to Rs 23,000 Crore. Already missile systems worth Rs 3500 Crore were delivered to the services. The weapon system is cost effective relative to equivalent systems in the global market.
Army chief briefs PM on security situation
Army Chief Gen Bikram Singh on Wednesday met Prime Minister Narendra Modi and is believed to have briefed him on the prevailing security situation in the country.

The Army Chief, who is also the Chairman, Chiefs of Staffs Committee, met the Prime Minister for around 15 minutes and is understood to have discussed the security scenario in the region as well.

The Army chief and the IAF chief also held separate meetings with Defence Minister Arun Jaitley and briefed him on the various issues faced by them.
The Army chief made a 40-minute presentation to the Defence Minister on various issues including the situation along the borders with China and Pakistan, the militancy situation in Jammu and Kashmir and the northeast, Defence Ministry officials said.

He is also understood to have briefed Jaitley on the critical requirements of the force in terms of equipment and its priority areas in the present scenario.

The status of the new 17 Strike Corps being raised along the border with China is also understood to have come up during the presentation given by the outgoing Army chief.

The Army is facing shortage of critical equipment such as artillery guns and its procurement cases including acquisition of 145 Ultra Light Howitzers, 197 light utility helicopters and several types of air defence weaponry are stuck due to one reason or the other.

IAF Chief Arup Raha briefed the Defence Minister on the operational preparedness of the force and the support required by it from the Government for strengthening its capabilities.

The 126 Rafale combat aircraft deal is also understood to have come up for discussion during the briefing. The deal has been stuck for the last two years and in view of the delays in getting new planes, the IAF has been forced to continue operating its vintage MiG-series aircraft, which have been frequently meeting with accidents.

Navy chief Admiral Robin Dhowan is expected to brief the Minister next week.
