In January 2007, after several months of intense negotiations, India and Israel signed a US$330 million deal to co-develop an all new generation of the Barak SAM, which was to be known as the Barak II. It has also been called Barak 8. They have worked out an agreement to develop and produce the long-range Barak air defence system for both the Indian and the Israeli militaries. The initial co-development funding is about US$350 million, of which IAI will finance 50 per cent. The venture is a tripartite one, between the DRDO, the Indian Navy, and IAI. The missile is referred to as the LRSAM in Indian Government literature, and will have a range of 70 km (43 mi).

The new missile, which will be based on the original Barak, is expected to feature a more advanced seeker, alongside range extensions (up to 70 km) that will move it closer to medium range naval systems like the RIM-162 Evolved Sea Sparrow or even the SM-2 Standard. The joint development offer was first made by Israel during Indian Navy Chief Admiral Arun Prakash’s visit to Tel Aviv in 2004. Israel successfully tested its improved Barak II missile on July 30, 2009. The radar system provides 360 degree coverage and the missiles can take down an incoming missile as close as 500 meters away from the ship. Each Barak system (missile container, radar, computers and installation) costs about $24 million. In November 2009 Israel signed a $1.1 billion contract to supply an upgraded tactical Barak-8 air defence system to India.

The dual pulse rocket motor for the SAM was developed by DRDO, and the prototypes were supplied to IAI for integration with IAI systems to develop the complete missile.The other variant of the LRSAM will be fielded by the Indian Air Force. Along with the Akash SAM, the LRSAM fills a longer range requirement and both types will complement each other. Each unit of the MR-SAM, would consist of a command and control center, with an acquisition radar, a guidance radar, and 3 launchers with eight missiles each. A 4-year, US$300 million System Design & Development phase to develop unique system elements and an initial tranche of the land-based missiles is estimated. The radars, C2 centers, TEL’s and missiles will be co-developed by Israel and India. In turn, IAI and its Israeli partners have agreed to transfer all relevant technologies and manufacturing capabilities to India allowing India to manufacture the LRSAM systems locally as well as support them.

In May 2010, the Barak-II missile was successfully test fired at an electronic target and met its initial objectives. The second test of the missile is to be held in India later this year. “More than 70 per cent of the content in the missile being developed with Israel would be indigenous.” DRDO chief V. K. Saraswat told The Economic Times.

Development and tests of the long-range anti-air / anti-missile

“In January 2006, India and Israel signed a $350m agreement to co-develop a new generation long-range surface-to-air missile (LR-SAM) for Indian Navy ships.”

Rafael Advanced Defence Systems and Elta Systems, a wholly owned subsidiary of IAI, were subcontracted for the Barak-8 joint development programme. Rafael provides missile interceptors, while Elta is responsible for the radar system.

The first test of Barak-8 missile took place in Israel in May 2010. The next test is planned to be conducted in Israel in 2012. The weapon qualification programme will involve eight test firings conducted in Israel and India prior to entry into service.

Components of the missile system, including the four-plane MF-STAR radars and shipboard electronic modules were delivered to India for final assembly.

Naval Barak-8 missiles will be installed on the three Project 15A Kolkata Class guided-missile destroyers under construction at the Mazagon shipyard in India. Delivery of the first frigate is scheduled for 2012, and Barak-8 missiles aboard the frigate are expected to become operational in 2013.

Four Project 15B Kolkata Class destroyers will also be armed with extended range surface-to-air missiles (ER-SAM). The extended-range missile can strike targets within the range of 100km

MF-STAR radar used on the jointly developed naval defence system

The MF-STAR radar will provide mid-course guidance updates for the missile initially after the launch from the ship. MF-STAR is a multifunction surveillance track and guidance radar for modern naval ships.

The radar uses multibeam, pulse Doppler and electronic counter-counter measures (ECCM) techniques to detect fast moving and low-RCS targets, even in complex environments / conditions and jamming environments.

The radar system provides 360° degree coverage and allows interception of incoming missile as close as 500m away from the ship. During the terminal phase, the second motor will be fired and active radar seeker will be activated to home on to the target.

Propulsion of the Israeli / Indian surface-to-air missiles

Propulsion power for the missile will be provided by a dual pulse rocket motor developed by DRDO. The prototypes were delivered to IAI for final assembly, along with other systems to produce the complete missile.

The rocket motor provides high manoeuvrability at target interception range throughout the wide envelope of the missile.

Naval barak

Naval Barak-8 is a long-range anti-air and anti-missile naval defence system being developed jointly by Israel Aerospace Industries (IAI) and the Defence Research & Development Organisation (DRDO) of India. Surface-to-air missiles (SAM) can counter attack aircraft, UAVs and incoming anti-ship missiles. The missile is expected to enter service with the Indian Navy in 2013.

In January 2006, India and Israel signed a $350m agreement to co-develop a new generation long-range surface-to-air missile (LR-SAM) for Indian Navy ships.

In April 2009, Israel signed a $1.1bn contract to deliver an upgraded Barak-8 air defence system to India. Deliveries are expected to be concluded by 2017.

The DRDO Nishant is an Unmanned Aerial Vehicle (UAV) developed by India’s ADE (Aeronautical Development Establishment) a branch of DRDO for the Indian Armed Forces. The Nishant UAV is primarily tasked with intelligence gathering over enemy territory and also forreconnaissance, training, surveillance, target designation, artillery fire correction, damage assessment, ELINT and SIGINT. The UAV has an endurance of 4 h 30 min. Nishant has completed development phase and user trials.

The 380 kg (840 lb) Nishant UAV requires rail-launching from a hydro-pneumatic launcher and recovered by a Parachute System. Launches at a velocity of 45 m/s are carried out in 0.6 second with 100 kW power and subsequent launches can be carried out in intervals of 20 minutes. The Mobile Hydro-Pneumatic Launcher (MHPL) system mounted on a Tatra truck weighs 14,000 kg (31,000 lb) and boasts of a life cycle of 1000 launches before requiring overhaul. Nishant is one of the few UAVs in the world in its weight-class capable of being catapult-launched and recovered by using parachute, thus eliminating the need for a runway as in case of conventional take-off and landing with wheels.

Development

To meet the Army’s operational requirement of an RPV it was decided in September 1988 that the Defence Research and Development Organisation would undertake the indigenous development of the UAV. The General Staff Qualitative Requirement (GSQR) was finalised by the Army in May 1990. The Nishant RPV made its first test flight in 1995. In July 1999, for the first time the Indian army deployed its new Nishant UAV system in the fight against guerilla forces backed by Pakistan in Kashmir. Nishant, which had been developed for battlefield surveillance and reconnaissance needs of the Indian Army, was test flown again in early 2002. The indigenous Unmanned Air Vehicle (UAV) Nishant developed by ADE,DRDO had completed its 100th flight by June 15, 2002. The Indian Army has placed an order for 12 Nishant UAVs along with ground support systems. Nishant Unmanned Aerial Vehicle (UAV) developed by DRDO for Indian Army was successfully flight tested near Kolar on 20 June 2008. Nishant has completed development phase and user trials. The present flight tests are pre confirmatory trials before induction into services.

Test flight

On Sunday 5 April 2009 DRDO launched a test flight of the Nishant UAV. The main goal was to test the performance of the Wankel engine used on the UAV. An abandoned World War II runway at a village near Kolar played host to the first ever flight of this indigenous rotary engine-powered UAV. The flight took off on early Sunday morning and climbed to an altitude of 1.8 km (5,900 ft) effortlessly before cruising for a duration of 35 minutes. The air vehicle was recovered safely at the intended place at a dried-up lake, after a total flight duration of 40 min. The engine, a Wankel rotary type, was the developmental project of the DRDO and was jointly designed and developed by NAL, a CSIR laboratory, VRDE, Ahmednagar and ADE, Bangalore. The provisional flight clearance for the first indigenous prototype engine was given by the certifying agency, RCMA. The engine was cleared for flight after rigorous ground endurance test runs. The Wankel engine weighs about 30 kg (70 lb), and this engine type is known for its high power-to-weight ratio in a single rotor category.

DRDO was satisfied with the test results. The performance of the engine during the flight met the requirements of the first flight of a engine in the air vehicle. This 55 hp indigenous engine is expected to replace the present imported engine of Nishant. The critical core engine, including the special cylinder composite nickel–silicon carbide coating and special aluminium alloy castings, was designed and developed by NAL. VRDE developed engine peripherals such as the ignition and fuel systems and ADE developed flight testing. The reconnaissance UAV, which has completed its user trials with the Indian Army, is expected to be handed over to the army shortly.

Nishant UAV again underwent crucial confirmatory user trials at Pokhran in April 2010. The trials began April 20 and were supposed to last for one week. A senior Army official at Pokhran said the trials are moving forward in a very satisfactory manner. “We are checking three crucial parameters: video quality, tracking ability and fall of gunshot [missed distance after firing]. These input performances are critical to our operations in the forward areas,” the official said. DRDO has delivered the first four UAVs to the Indian Army at a cost of 800 million INR ($17.9 million).

According to the Times Of India, two UAVs crash-landed in Jaisalmer district near the India-Pak border due to change in wind direction on Apr 28th and Apr 30th. Confirming the news, a DRDO official said, “The user trials were going on and during the flight there were some technical snags owing to which the craft was landed using parachutes.” He said, “But the landing was done safely and no one was hurt in the process. Though before our officials could reach to get the craft back, villagers damaged the aircraft and took away some equipment.”

On 3rd Feb 2011 Nishant UAV has successfully completed confirmatory trials conducted by the Indian Army at Pokhran, Rajasthan
