DRDO Says Arjun MkII Version Tanks Are Ready For Trials

Within a year of the government approving a project for an upgraded indigenous main battle tank (MBT), India's defence research agency has readied a Mark II version that will undergo summer and winter trials this year.

The defence ministry had last May given its nod to the Defence Research and Development Organisation (DRDO) to develop the Arjun MkII MBT which would have enhanced features over the first lot of 124 tanks that have been delivered to the army over the last two years.

'The Arjun MkII tanks will go for summer trials this year and later for winter trials at the end of 2011,' a defence ministry official said here Monday.

The army is already operating two regiments of Arjun tanks in the western sector and has placed an order for an additional 124 - two regiments - of the 58-tonne tanks from the Avadi-based manufacturer, Heavy Vehicles Factory.

The army gained confidence in operating the Arjun tanks, despite the initial hesitation, after the first two regiments were pitted against the Russian-built T-90 MBTs early last year in comparative trials in the desert terrain.

The Arjuns, army officers said, had outsmarted the T-90s in all the parameters set for the trials and had prompted the army top brass to admit that the tank was one of the best they had operated.

The Arjun MkII will have about a dozen changes from the first lot, being armed with missile firing capability through a laser homing device.

Though the missile system had been tested on the MkI version of the tank about five years ago, it did not form part of the final design of the initial 124 delivered to the army, and nor will it be mounted on the second lot of 124, ministry officials said.

The system, they said, would have a range of about eight kms, within which it could destroy enemy tanks after homing on to the target using a laser.

Other modifications include better explosive-reactive armour for the tank to protect it from enemy missiles and rockets, improving the sighting facility to provide it a wider view of the battlefield, including night vision capability, and a better communication system.

DRDO Tests K-15 SLBM

The DRDO has rescheduled the test-firing of submarine launched ballistic missile ( SLBM) K-15 to January 31. It was supposed to be test-fired from an underwater platform off the Vishakhapatnam coast on January 20.

"The test was first scheduled on January 16, but was postponed to January 20. Now it has again been rescheduled to January 31 due to delay in arrangements. It is a coordinated exercise of both land and Navy personnel," a source said.

"India can join the league of five nations, Russia, US, France, Britain and China, with the successful launch of the K-15 missile. These countries already possess advanced missiles that can be launched from a submarine," sources said.
The indigenously developed K-15 or the B-05 missile are 10 metres in length, one metre in diameter and weighs ten tonnes with a strike range of around 700 km.

This missile uses solid propellant and carries a conventional payload of about 500 kg to one tone and also be fitted with a tactical nuclear warhead. "The missile is ready for the test. But preparation is on for locating the Pontoon (replica of a submarine) inside the sea. The tracking machineries and technical equipment have been shifted from the integrated test range to Vishakhapatnam," the source added.

The K-15 missile has been tested at least six times and is in serial production. The missile was initially test-fired under the name of Sagarika project. While its launching was recorded partial success twice, the rest were claimed as "successful trials" by the DRDO.

The missile, which can be compared with the Tomahawk missile of US, is India's response to Pakistan's Babur missile. The source further said that the Navy has reportedly been insisting for the test of K-15's cruise variant as it is hard to be obstructed and has pinpoint accuracy.

"Cruise missiles are more difficult to detect and hence less vulnerable to anti-missile defence, which can track and destroy ballistic missiles with comparative ease," a defence scientist said. "Besides, the K-15 missile, India has another missile which can also be launched from a submarine. In a joint collaboration with Russia, a submarine-launched version of BrahMos cruise missile has been developed," he added.

DRDO Says Arjun Mark-II Will be completed by July 2011

The phase one production of Arjun Mark-II will be completed by July 2011 and phase two production with 93 new improvements will be completed by June 2012, said P Sivakumar, Director of Combat Vehicle Research and Development Establishment, a wing of the DRDO.

In Phase-I, 45 tanks will roll out with 56 upgrades, including the missile firing capability and the enhanced night vision, and in Phase-II, the remaining 79 tanks, with all the 93 improvements, will come off the assembly line. “By 2013-14, the first batch of 30 tanks will reach the ground,” Sivakumar told Express.

Addressing a seminar at Anna University, Sivakumar also mentioned the need for defence establishments to reduce the weight of combat vehicles like tanks. “Material sciences and nanotechnology play a significant role in this change. At present Arjun tanks weigh 60 tonnes. But there may be a demand to reduce the weight to 50 tonnes to improve mobility. This can be achieved to some extent by applying nanotechnology in reducing the thickness of armors while retaining their strength,” he said.

The DRDO research and innovation center at IIT-Madras Research Park will try to work and address such needs by collaborating with educational institutions, Sivakumar said.

“The center will become operational by July and we look to pool in resources from students of IIT-M and Anna University to conduct futuristic research at this centre, different from projects going on in the regular DRDO labs,” he said.

The focus of this research centre, according to Sivakumar, will be on developing the suspension technology. “India is a leader in hydropneumatic suspension technology and we are looking to broaden the scope further through this centre,” he said.

DRDO Official Sees Good Export Potential For Tejas Fighter Jets

DRDO said there could be a good export market for Tejas, the country's first indigenously built supersonic fighter aircraft, if the Centre okayed it.

Speaking to The Hindu recently, he said the DRDO had already received enquiries for Tejas from various countries.

The plane was given Initial Operating Clearance (IOC) only recently by Defence Minister A. K. Antony. The Light Combat Aircraft (LCA) was the star attraction at the recently conducted Aero India air show in Bangalore, in which 45 countries took part.

Saying India was among very few countries in the world capable of producing fighter planes, Mr. Selvamurthy said that third world countries, developing countries and even some of the developed countries were markets for Tejas.

Since the production cost, research and development cost of the Tejas was relatively low compared to the other fighter aircraft, India could sell the Tejas at a lower price.

Since the production models were doing extremely well, there wouldn't be any problem in obtaining Final Operating Clearance (FCA) for the fighter aircraft, he said.

In line with the requirements of the Indian Air Force, the process of fine tuning Tejas, including flight envelope, flight manoeuvrability, payload integration and other issues have been taken up.

The fighter plane is expected to get the Final Operating Clearance in the first quarter of 2012, the official said.

Production completed

Mr. Selvamurthy said out of 40 Tejas aircraft ordered by the Indian Air Force (IAF), the Hindustan Aeronautical Limited (HAL) had already completed production of 10. It had already been figured in the inventory of IAF. Another 20 aircraft would be completed after the Final Operating Clearance is given.

It is expected that an order might be received for a large number of aircraft in 2012. HAL had also geared up its capacity building facilities, including assembly line and others.

It planned to increase the capacity to increase the number of aircrafts built in a year to meet the growing demand.

The distinguished scientist said the cost of aircraft, which stood around Rs.130 crore, was expected to come down once the HAL started large-scale production of Tejas.

The country had been placed in comfortable position as far as Tejas was concerned as it was not depended upon anybody for lifecycle support, maintenance cost and others because of the indigenous technology.

DRDO Says Kaveri Engine Can Power Combat Drones 80 KN OF Thrust Available Now

DRDO officials say the Kaveri aero-engine, which incidentally is over 22 years in the making by now with a sanctioned cost of Rs 2,893 crore, can power unmanned combat aerial vehicles (UCAVs) because they "do not require the kind of higher thrust" needed for the indigenous Tejas LCA (light combat aircraft).

" Nine prototypes of Kaveri engine and four prototypes of Kaveri Core (Kabini) engines have been developed with over 2,000 hours of testing...the engine is proven with almost 80 kilonewtons (kN) of thrust now, which is enough for our UCAVs (Tejas requires 90 kN)," said an official.

This comes even as DRDO has now begun preliminary work on developing stealth UCAVs, under the secretive 'autonomous unmanned research aircraft' programme. This UCAV will weigh less than 15 tonnes, fly at altitudes of 30,000 feet and fire missiles and bombs with precision, as earlier reported by TOI.

DRDO has also come up with a modified Kaveri version, by "designing a free-power turbine to generate shaft power", for propulsion of warships. The Navy, as per DRDO, has shown "a lot of interest" in the engine which has a 12 MW power output.
"With Kaveri, we have proven several gas turbine technologies for a variety of applications. Indian Railways is also interested in knowing whether Kaveri can be used for powering trains," said the official.

DRDO is now also trying to tie up with French company Snecma to jointly develop the "90kN thrust class of upgraded Kaveri engines" for the future requirements of IAF. But the fact remains that the Kaveri project's dismal performance has forced India to ink a $822 million contract for 99 General Electric's F-414 engines, with an option to go for another 49 engines at a later stage, to power the Tejas Mark-II version.

While the first 20 Tejas will be powered by GE-404 engines, the next six Mark-II squadrons (16-18 jets in each) will have the new more powerful GE F-414 engines. Under the LCA project, which itself has been 28 years in the making with an almost 3,000% jump in overall developmental costs, IAF hopes to have its first two fully-operational Tejas squadrons based at the Sulur airbase (Tamil Nadu) by 2015 now.
