India to have a sharper eye in the sky soon

Bangalore: After successfully demonstrating the Akashdeep aerostat system, the Defence Research and Development Organisation (DRDO) will develop a bigger and better aerostat system with additional payload. DRDO chief controller, R&D (Aerospace & Services Interaction) Dr Prahlada told that the new aerostat system will be bigger in size compared to the medium-range Akashdeep.
India's new eye in the sky can carry out surveillance up to a radius of 450-500kms and is being developed based on the feedback from the Air Force and the Army received during the Aero India 2011. The new system will be used by the army and paramilitary forces.
Dr Prahlada said paramilitary forces have showed interest in the aerostat which can be used for surveillance activities in the Maoist-infested areas.
The aerostat system, to be developed by the Agra based by Aerial Delivery Research and Development Establishment (ADRDE), will be equipped with a wide range of payloads. It can carry out surveillance during night and in low-visibility condition and also intercept a variety of communication.
The aerostats gimbals, with 360 degree azimuth freedom, can carry out steering, scanning and tracking with high precision.
Defence experts say the deployment of aerostats at the borders along with the Airborne Early Warning & Control System (AEW&C) will redefine the battle surveillance capabilities as armed forces can neutralise attacks from adversaries well in advance.
In addition to the aerostat, India's indigenous Airborne Early Warning & Control System (AEW&C) which is being built on a modified Embraer EMB-145 aircraft in Brazil will be brought to India in August, said Prahlada.
The modified aircraft will be integrated with Active-Array Antenna Unit, mission systems, radar, etc by the Bangalore- based Centre for Airborne Systems (CABS).
"Following the integration the first flight is expected to take place in January next year," he added.

DRDO Augments Air Defence by Developing Interceptor Missile with 5,000 Kilometer Range
Posted on:May 17, 2011

After having proven its ballistic missile defence capability with its indigenously developed interceptor missile in the endo-atmospheric and exo-atmospsheric zone, India has announced that it has begun work on superior air defence systems that can bring down hostile incoming missiles at a distance of 5,000 kilometers. This project will be the second phase of the Ballistic Missile Defence (BMD) system being developed by India and it is in the initial design and testing stage.

The air-defence system is being developed by state-run Defence Research and Development Organization (DRDO) which is in the first phase where the BMD system can intercept an incoming aerial threat 2,000 kilometers away. The BMD system which can ward off missiles at a distance of 5,000 kilometers will be the second phase of the same project undertaken by DRDO.

According to DRDO, the need for collaboration with any foreign country maybe considered to compliment the process of developing such a critical BMD system if it augurs well for India and its development process. DRDO top brass added that the BMD system was not an R&D project but a concrete and decisive project to show indigenous capabilities. India is also involved in the development of the Long Range Tracking Radar (LRTR) for the BMD systems and it will have 80 per cent indigenous components for the 2nd phase of the BMD project.

In March this year, trials to develop a full-fledged, multi-layer ballistic missile defence system were successfully carried out. The trial consisted of firing an interceptor missile to destroy the incoming hostile ballistic missile at an altitude of 16 kilometers. The interceptor boasted new technologies such as directional warhead, fiber-optic gyroscopes and a radio-frequency seeker that guided the interceptor to attack the incoming enemy missile. As of now, these advanced systems are ready for integration into the air defence assets of the country which will establish a reliable ballistic missile shield.

According to DRDO Chief Dr.V.K Saraswat, the Phase 2 of the BMD system programme will require longer range radars and new hypersonic interceptor missiles flying at Mach 6 or 7 with greater stealth and capacity to act against ballistic missile defence counter measures. In other words, there will be greater interception at high altitudes wherein the system will manage multiple attacks.

The BMD system developed by DRDO will be executed in two phases under a capability-based deployment plan. The first phase will entail the development and deployment of a system for defense against missiles with less than 2,000 kilometer range. In the second phase, system capability will be upgraded to defend against missiles with 5,000 kilometer ranges where it can additionally deploy more maneuvers. The first phase is to be deployed by 2012 and second phase system by 2016.

Ajai Shukla: Indigenising defence - the 70:30 fallacy

Defence indigenisation has long been more a Ministry of Defence (MoD) slogan than reality. Defence Minister A K Antony pays regular lip service to reversing the 70:30 ratio: reducing the foreign component of Indian defence from 70 per cent to 30 per cent. In practice, indigenisation has been, with apologies to Greta Garbo, an illusion, wrapped in a fallacy, cloaked in deception.

The empirical reality of "indigenisation" is evident in the Indian Navy, the only service that pursues indigenisation systematically (the Indian Air Force and the Army talk the talk but oppose indigenisation in practice, demanding aircraft, tanks and guns now, not ten years down the line). The navy takes justifiable pride in building most of its warships in Indian shipyards, but a closer examination reveals that indigenisation is only skin-deep. Defence shipyards have developed the crucial skills needed for designing and constructing sophisticated warships, and for harmonising myriad sensors and weapons into an integrated battle management system. But there is little headway in indigenising the multiplicity of components and systems that are the vital innards of a battleship.

Consequently, India's four defence shipyards – the flagship Mazagon Dock Ltd, Mumbai (MDL); Garden Reach Shipbuilders & Engineers, Kolkata (GRSE); Goa Shipyard Ltd (GSL); and the newly acquired Hindustan Shipyard Ltd, Visakhapatnam (HSL) – must necessarily look overseas for the engines, gas turbines, propulsion systems, gearboxes, generators, hydraulic systems, air-conditioning and countless other systems, which add up to the bulk of the cost of modern warships.

These are all lost opportunities for India's private sector companies, which could be building these systems as their route into the lucrative business of defence production. Examine the figures. From the navy's budget of Rs 21,000 crore this year (all figures rounded off), almost 60 per cent, or Rs 12,000 crore, is earmarked for capital expenditure. Of this, Rs 4,000 crore will be disbursed directly to foreign shipyards that are constructing Indian warships, while Rs 8,000 crore will be paid to Indian shipyards. On the face of it, that would appear like a healthy 66 per cent indigenisation rate, close to Mr Antony's target.

Unfortunately, only a small share of this goes to the Indian shipbuilder. MDL retains just 25 per cent of the cost of each warship it produces, with 75 per cent being paid to foreign suppliers for the systems mentioned above. GRSE pays out 65 per cent and GSL remits 55 per cent abroad, not because they are better at indigenising but because their vessels use lower-end technology that is available in India.

The shocking statistic is that India has a 100 per cent indigenisation rate in jungle boots, blankets and similar low-tech equipment. But in critical technologies, we import 85 per cent of our needs. And in warship-grade and aerospace-grade components, we have indigenised just 5 per cent of our requirement; 95 per cent still comes from abroad. An example is Hindustan Aeronautics Ltd's Dhruv helicopter, designed and integrated in India, but 90 per cent foreign in physical content.

This regrettable situation exists largely because the MoD, particularly its Department of Defence Production (DDP), has failed to coordinate and sponsor the development of indigenous capability. Warship builders still import even warship- grade steel, the toughened alloy that comprises the basic structure of a modern battleship. This is not because the technology is beyond us. Years ago, India's public sector metallurgical establishments – the Defence Metallurgical Research Laboratory; Mishra Dhatu Nigam; and Steel Authority of India Ltd – developed and manufactured warship-grade steel (termed D 40S), which has been used in the navy's reputed Shivalik class frigates. But cross-ministerial coordination is needed to produce the relatively small volumes required for warship programmes while remaining profitable for both steel makers and shipyards. Essar Steel had offered to produce warship steel, subject to some conditions. But the MoD has preferred to continue reliance on import.

In 2003 the navy addressed the lack of depth in indigenisation with a "15 Year Indigenisation Plan", which was subsequently revised up to 2022. This forecasts the warship programme's requirement of equipment and systems, hoping for import substitution by bringing in the private sector. A similar initiative last year, broadened to all three services, was the DRDO's "Technology Perspective & Capability Roadmap", which details the technologies that the military requires and urges the private sector "to offer firm commitments in partnering the MoD in developing contemporary and future technologies as well as productionalising [sic] equipment required by the Armed Forces".

But these useful baseline documents are only a starting point for an indigenisation thrust. Private sector corporations that are interested in defence production would still require handholding and funding for their initially non-productive R&D. The funding is available – each year the MoD has been earmarking some Rs 2,000 crore for "Make" procedure projects, without a single rupee having ever been paid out – but nobody in the MoD has taken clear ownership of such an initiative.

It is time for the defence ministry to step up to the plate. They have already identified 61 critical technologies – especially materials and components that can be used across a broad range of sub-systems and systems – that India badly needs for developing higher technological capabilities. A nationally synergised effort is needed, which must also explore obtaining specific technologies through the offset route.

We have learnt how to swim at the deep end of the pool, developing the complex abilities needed to design and integrate warships, aircraft and tanks, without developing the broader research and industrial ecosystem that sustains a defence industrial base. It is time to deepen and broaden indigenisation, by developing the materials, components and sub-systems that will not only substitute defence imports, but also provide technological "trickle down" to energise the national industrial base.
