BOEING P-8I NEPTUNE [K65298] 03The Boeing P-8 Poseidon (ALSO modified as neptune for indian navy) (formerly the Multimission Maritime Aircraft or MMA) is a military aircraft currently being developed for the United States Navy (USN). The aircraft is being developed by Boeing Defense, Space & Security, modified from the 737-800.

The P-8 is intended to conduct anti-submarine warfare (ASW) and shipping interdiction and to engage in an electronic intelligence (ELINT) role. This will involve carrying torpedoes, depth charges, SLAM-ER anti-ship missiles, and other weapons. It will also be able to drop and monitor sonobuoys. It is designed to operate in conjunction with the Broad Area Maritime Surveillance unmanned aerial vehicle. The P-8 has also been ordered by the Indian Navy.

Boeing approached the U.S. Air Force in 2010 about replacing the E-8C Joint STARS fleet with a modified version of the P-8 at the same cost Northrop Grumman proposed for re-engining and upgrading the E-8s. The proposed version is named P-8 Airborne Ground Surveillance (AGS) and would integrate an active electronically scanned array (AESA) radar, and have ground moving target indicator (GMTI) and synthetic aperture radar (SAR) capabilities.

The main distinguishing feature of the P-8 AGS is pod-mounted radar, fixed to the lower centerline of the fuselage; the pod is lowered so the engine nacelles do not interrupt the radar’s line of sight. Two aft ventral fins on lower aft provide stability for the aircraft. The P-8 AGS also uses the P-8A’s Raytheon AN/APY-10 multi-mission surface search radar.Boeing has campaigned for a fleet of P-8 AGS aircraft instead of re-engining the E-8s. The Air Force’s Analysis of Alternatives (AoA) of the JSTARS platform began in March 2010 to review options for performing the JSTARS mission. An initial decision on the AOA was expected in September 2011

The P-8 is a militarized version of the 737-800 with 737-900-based wings. The airframe uses a 737-800-based fuselage that is similar to but longer than the 737-700-based C-40 Clipper. The P-8 has a strengthened fuselage and 767-400ER-style raked wingtips, instead of the blended winglets available on 737NG variants. The five operator stations (two Naval Flight Officers plus three enlisted Aviation Warfare Operators/Naval Aircrewman) are mounted in a sideways row, along the port side of the cabin. None of these crew stations have windows. One observer window is located on each side of the forward cabin.

The P-8 features the Raytheon APY-10 multi-mission surface search radar.[29] The P-8I will feature an international version of the APY-10. A short bomb bay for torpedoes and other stores opens behind the wing. The aircraft also includes six additional body fuel tanks for extended range from Marshall Aerospace; three of the tanks are located in the forward cargo compartment and three in the rear. In-flight refueling is via a receptacle on top of the forward fuselage, just aft of the cockpit.

In U.S. service, the Poseidon will be complemented by the Broad Area Maritime Surveillance UAV system, which will provide continuous surveillance. The system is expected to enter service around 2010. Around 40 UAVs based on the RQ-4 Global Hawk will be used in the program. Because of the cancellation of Lockheed Martin’s Aerial Common Sensorproject, Boeing will propose a signals intelligence variant of the P-8 to service the requirement for the U.S. Navy.

INDIA

In January 2008, Boeing proposed the P-8I, a customized export variant of the P-8A, for the Indian Navy. On 4 January 2009, India’sMinistry of Defence signed an agreement with Boeing for the supply of eight P-8Is at a total cost of US$2.1 billion. These aircraft would replace Indian Navy’s aging Tupolev Tu-142M maritime surveillance turboprops. Each aircraft has an average cost of about US$220 million. The deal makes India the first international customer of the P-8, and also marks Boeing’s first military sale to India. In October 2010, India’s Defence Acquisition Council of the Ministry of Defence approved the purchase of four additional P-8Is. In March 2011, it was reported that India was to order four additional P-8s from Boeing later in the year. India plans to order another 12 P-8Is at a later time.

The Data Link II communications technology for the P-8I was received by Boeing from Bharat Electronics Limited in April 2010. The communications system will enable exchange of tactical data and messages between Indian Navy aircraft, ships and shore establishments. Boeing will install the system during P-8I final assembly. The IFF, system from BEL was also handed over to Boeing for integration with P-8I in December 2010.

Flight testing of P-8Is began in July 2012, with deliveries planned to start in 2013. The first P-8I was handed over to an Indian naval team at the Boeing facility at Seattle on 19 December 2012. The Indian Navy is to fly it to India along with the second and third aircraft after they handed over in May and June of next year.

Indian Navy has 8 P-8I aircraft on order; deliveries began in December 2012.

   The Sukhoi/HAL Fifth Generation Fighter Aircraft (FGFA) is a fifth-generation fighter being developed by India and Russia. It is a derivative project from the PAK FA (T-50 is the prototype) being developed for the Indian Air Force (FGFA is the official designation for the Indian version).

Two separate prototypes will be developed, one by Russia and a separate one by India. According to HAL chairman A.K. Baweja (speaking shortly after the India-Russia Inter-Governmental Committee meeting on 18 September 2008), the Russian version of the aircraft will be a single-seater, the Indian version will be a twin seater, analogous to the Su-30MKI which is a twin seat variant of the baseline Su-27. The plane is scheduled to enter series production in 2019.

Development

India will eventually spend over $25 billion to induct 166 PAK FA and 48 FGFA advanced stealth fighter aircraft. This will be in addition to the huge investments to be made in co-developing FGFA, as with the infrastructure required to base, operate and maintain such jets in India. IAF’s Air Chief Marshal Naik said that the FGFA will be a swing-role fighter with advanced avionics, super cruise, stealth to increase survivability, enhanced lethality, 360 degree situational awareness, smart weapons, data-links, high-end mission computers and the like. Along with 126 medium multi-role combat aircraft, which India plans to acquire, 270 Sukhoi-30MKIs contracted from Russia, and 220 indigenous Tejas Light Combat Aircraft, the FGFA will be the mainstay of India’s air combat fleet for the foreseeable future. This, in addition to the remaining 50 odd Mirage 2000 fighters, 61 MIG-29 SMT, and the 125 MIG-21 Bison operational till 2017, will help the IAF to reach the sanctioned strength of 44 squadrons.

The joint-venture borrows heavily from the success of the Brahmos project. Russia and India had agreed in early 2007 to jointly study and develop a Fifth Generation Fighter Aircraft Programme (FGFA). On October 27, 2007, Asia Times quoted Sukhoi’s director, Mikhail Pogosyan, “We will share the funding, engineering and intellectual property in a 50-50 proportion.” The Indian version, according to the deal, will be different from the Russian version and specific to Indian requirements. While the Russian version will be a single-pilot fighter, the Indian variant will have single and twin-seat configuration based on its operational doctrine which calls for greater radius of combat operations. The wings and control surfaces need to be reworked for the FGFA. Although, development work has yet to begin, the Russian side has expressed optimism that a test article will be ready for its maiden flight by 2009, one year after PAK FA scheduled maiden flight and induction into service by 2015.

By February 2009, as per Sukhoi General Director Mikhail Pogosyan, India will initially get the same PAK FA fighter of Russia and the only difference will be the software.

In 2011, it was reported that IAF will induct 148 single seat as well as 66 dual seat variants of the FGFA. IAF plans to induct the first lot of aircraft by 2017.

Design

Although there is no reliable information about the PAK FA and FGFA specifications yet, it is known from interviews with people in the Russian Air Force that it will be stealthy, have the ability to supercruise, be outfitted with the next generation of air-to-air, air-to-surface, and air-to-ship missiles, and incorporate an AESA radar. The FGFA will use on its first flights 2 Saturn 117S engines (about 14.5 ton thrust each). The 117S is an advanced version of the AL-31F, but built with the experience gained in the AL-41F program. The AL-41F powered the Mikoyan MFI fighter (Mikoyan Project 1.44). Later versions of the PAK FA will use a completely new engine (17.5 ton thrust each), developed by NPO Saturn or FGUP MMPP Salyut.

Three Russian companies will compete to provide the engines with the final version to be delivered in 2015-2016.

HAL negotiated successfully to get a 25 per cent share of design and development work in the FGFA programme. HAL’s work share will include critical software including the mission computer, navigation systems, most of the cockpit displays, the counter measure dispensing (CMD) systems and modifying Sukhoi’s single-seat prototype into the twin-seat fighter as per the requirement of the Indian Air Force (IAF).

Russian expertise in titanium structures will be complemented by India’s experience in composites like in the fuselage. A total of 500 aircraft are planned with option for further aircraft. Russian Air Force will have 200 single seated and 50 twin-seated PAK FAs while Indian Air Force will get 166 single seated and 48 twin-seated FGFAs. At this stage, the Sukhoi holding is expected to carry out 80% of the work involved. Under the project terms, single-seat fighters will be assembled in Russia, while Hindustan Aeronautics will assemble two-seaters.

According to HAL chairman A.K. Baweja on 16 September 2008, HAL will be contributing largely to composites, cockpits and avionics. HAL is working to enter into a joint development mechanism with Russia for the evolution of the FGFA engine as an upward derivative of the AL-37. Speaking to Flight magazine, United Aircraft chief Mikhail Pogosyan said India is giving engineering inputs covering latest airframe design, Hi-Tech software development and other systems.

PAK FA and FGFA

The difference between PAK FA and the FGFA will be similar to that between Su-30M and Su-30MKI. Su-30M is a standard Russian version of a plane, whereas the Su-30MKI (MKI stands for “Modernizirovannyi Kommercheskiy Indiski” meaning “Modernized Commercial India”) was jointly-developed with India’s Hindustan Aeronautics Limited for the Indian Air Force. The Su-30MKI includes 2.5D Thrust Vectoring Control (TVC) and canards. It is equipped with a multi-national avionics complex sourced from India, Israel, Russia and France. Further the FGFA will be predominantly using weapons of Indian origin such as Astra, a Beyond Visual Range missile (BVR) being developed by India, although in keeping with the Russian BVR doctrine of using a vast variety of different missiles for versatility and unpredictability to countermeasures, it can be expected to have compatibility with many different missile types. Ashok Baweja stated that “The Indian FGFA is significantly different from the Russian PAK FA because a second pilot means the addition of another dimension, development of wings and control surfaces.”

The FGFA may also include systems developed by third parties.

The completed joint Indian/Russian versions of the single seat or two seat fighters will differ from the current flying prototypes through the addition of stealth, supercruise, sensors, networking, and combat avionics for a total of 43 improvements.

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 Indian naval designers have been working on cutting edge ships of the future. CNN-IBN caught up with naval experts at the President’s Fleet Review to find out what the Indian navy fleet will look like, 10 years from now. The Indian Navy will have a three hulled ship or the Trimaran virtually invisible to the enemy radar because of its stealth design. Its deck gun and missiles have been concealed in every respect.

KN Vaidyanathan, DG, Naval Design, said, “Stealth means reduced radar cross section, reduced underwater noise as well as reduced infrared signature apart from other electric signatures.”

“We are also going to use multi-function radars, already our destroyers and new gen frigates are going to have multi-function radars and they are using the vertical launch systems,” he added.

The Trimaran concept design follows in the wake of the Navy’s first stealth design, the Project 17 Shivalik class ships, two of which are now at sea with a third on the way.

But the Navy is banking on the Shivalik’s successor, the Project 17 Alfa stealth vessel, which will have missile silos flush with the deck and torpedo launchers blending along the sides of the vessel. There will also be a concealed hangar for a Kamov helicopter. Naval designers admit that US concepts have influenced some of their ideas.

“If you look at the LCS design of the US Navy, they are moving on the seaframe concept and mission modularity.The idea is to have a basic seaframe for the platform and have a mission module so that you can have role changes for the ship and there can be a quick turnaround of roles,” Vaidyanathan said.

With an eye on the future, the Navy is moving towards modular construction and may even participate in Britain’s Global Combat Ship project where individual navies can use a common low cost platform to fit their own weapons and systems.

The INS Vishal will follow her sister, the INS Vikrant, into Indian Navy service in the next decade and sport a higher displacement and flat-top flightdeck.

The INS Vishal (“Immense”) is the second of two new indigenous Indian Navy carrier designs currently under construction (2012). The INS Vishal is following the INS Vikrant into service to which the latter is expected to be commissioned sometime after 2017 due to ongoing project delays. Prior to these two endeavors, the Indian Navy relied largely on existing foreign types of British or Soviet/Russian origin refitted for Indian Navy use and, as such, these new carrier developments will stand as a huge symbol of national pride. The INS Vishal project is headed by the Naval Design Bureau with the vessel requirements expected to be finalized by the end of 2012.For years. the Indian Navy made use of two ex-British Royal Navy carriers under the local names of INS Vikrant (R11) and INS Viraat (R22) though these aging systems eventually passed their prime by the end of the 1980s and thought was given towards their formal retirement. A new indigenous initiative was announced in 1989 intended to stock the Indian Navy with a homegrown solution under the “Air Defence Ships” (ADS) project. Construction would consist of two 28,000 ton vessels centered on the launching and recovery of the British BAe Sea Harrier Vertical Take-Off and Landing (VTOL) strike aircraft. However, economic hardship struck the Indian nation and the project fell to naught.In 1999, the economic troubles had subsided to which the indigenous carrier initiative was brought to light once more. By this time, the Sea Harrier stable had grown thin to under a dozen aircraft and a more flexible aircraft carrier solution was directed under the new “Indigenous Aircraft Carrier” initiative. The class would include the initial 40,000 ton INS Vikrant (not to be confused with the original R11) and her sister, the 65,000 ton INS Vishal. Both would be capable of launching the newer Mikoyan MiG-29K Fulcrum navy fighters and navalized helicopters as required. The Vikrant was assigned a STOBAR configuration (Short Take-Off But Arrested Recovery) to which a “ski jump” ramp was affixed to the bow end of the ship for the required short-take off requirement. The Vishal, however, would be drastically different in scope and function, being of the CATOBAR configuration (Catapult-Assisted Take-Off But Arrested Recovery) – in essence a “flat top” deck more in line with American Navy offerings. This particular configuration would now make it possible to launch heavier and dimensionally larger mission-minded fixed-wing aircraft such as Airborne Early Warning (AEW) types and give the Indian Navy a considerable edge in the South Asian-Pacific Theater – particularly against the likes of China and Pakistan.Design plans were drawn up in 2001 to which funding was secured in 2003 and construction of the Vishal began in 2012 (continuing today). At the end of the project, the Vishal will be a conventionally-powered aircraft carrier fitted with 4 x General Electric LM2500+ series gas turbine engines delivering to two shafts. Top speed will be 28 knots in ideal conditions with a range out to 7,500 nautical miles. Dimensions include a running length of 860 feet with a 200 foot beam and 28 foot draught. The crew complement is expected to be 1,400 officers, sailors, service personnel, airmen and mechanics.The bread and butter of the Vishal carrier will be its air wing comprised of 29 fixed-wing aircraft and 10 rotary-wing helicopters. The primary mount is expected to be the Russian Mikoyan MiG-29K Fulcrum, the navalized form of the successful land-based lightweight fighter. These will be supplemented or replaced by the indigenous delta-winged HAL Tejas aircraft (navalized). However, the Indian Navy is also interested in stocking heavier aircraft such as the Sukhoi Su-33, Boeing F/A-18 Hornet or French Dassault Rafale (the Rafale in particular has just been selected by the Indian Air Force to replace its stock of outdated Mikoyan MiG-21 Fishbed fighters). The Grumman E-2 Hawkeye has been mentioned for the fixed-wing AEW role as has a modified AEW version of the Boeing V-22 Osprey tilt-rotor helicopter. Helicopter types expected include the Russian Kamov Ka-31 series (Airborne Early Warning (AEW)) or the British Westland Sea King (Anti-Submarine Warfare (ASW)) – both navalized for operations at sea/over water.The vessel will be defended by a network of 4 x 76mm Otobreda guns, surface-to-air missile launchers and a Close-In Weapon System (CIWS) such as the 20mm American “Phalanx”. A selex RAN-40L L-band early warning radar (EWR) will be part of the extensive and advanced sensor and processing system.At this writing (2012), the arrival of the INS Vishal is still some time away as the Indian Navy commits to other higher profile requirements. The launch date for the vessel is tentatively scheduled for sometime in 2017 with sea trials to be undertaken in 2020 and formal commissioning in 2022. Sources indicate that the commissioning year is closer to 2025 due to the ambitious nature of the program and much thought given to finding local solutions without foreign assistance. This will push existing carriers such as the INS Viraat into service beyond 2014. The INS Vikramaditya – a converted ex-Soviet/Russian Kiev-class carrier – is scheduled to be commissioned at the end of 2012 as a more viable, modernized solution for the Indian Navy until the arrival of the INS Vikrant and INS Vishal.

The HAL Rudra (Devanagari: रुद्र, “The God Of The Tempest”) aka ALH-WSI is an armed version of HAL Dhruv. Rudra is equipped with Forward Looking Infra Red and Thermal Imaging Sights Interface, a 20 mm turret gun, 70 mm rocket pods, Anti-tank guided missiles and Air-to-Air Missiles.

Design

The version is equipped with SAAB supplied Integrated Defensive Aids Suite (IDAS) with Electronic Warfare self-protection which is fully integrated into the modern glass cockpit.

ALH-WSI has undergone integration trial for armament and electro-optical systems.

A final round of weapon firing trials is scheduled in September 2011, starting with its 20-mm turret gun, followed by trials of its 70mm rockets and MBDA Mistral air-to-air missiles in November.

Initial Operational Clearance (IOC) is expected by late 2012 with deliveries of the production helicopters starting on or before 2013.

As per the initial orders, close to 70 Rudras are to be supplied to Indian armed forces. “It has comfortably-exceeded the payload and performance requirements at 6 km height. It has integrated sensors, weapons and electronic warfare suite using an upgraded version of the glass cockpit used in the Mk-III. The cockpit avionics is a state-of-the-art technology when it comes to helicopters. The sensors include stabilised day and night cameras, Infra-Red imaging, as well as laser ranging and designation,” sources said.

                                             AVATAR (Sanskrit: अवतार) (from “Aerobic Vehicle for Hypersonic Aerospace TrAnspoRtation”) is a single-stage reusablespaceplane capable of horizontal takeoff and landing, being developed by India’s Defense Research and Development Organizationalong with Indian Space Research Organization and other research institutions; it could be used for cheaper military and civiliansatellite launches.

When operational, it is planned to be capable of delivering a payload weighing up to 1,000 kg to low earth orbit. It would be the cheapest way to deliver material to space at about US$67/kg. Each craft is expected to withstand 100 launches.

Concept

The idea is to develop a hyperplane vehicle that can take off from conventional airfields, collect air in the atmosphere on the way up, liquefy it, separate oxygen and store it on board for subsequent flight beyond the atmosphere. The AVATAR RLV was first announced in May 1998 at the Aero India 98 exhibition held at Bangalore. It is planned to be the size of a MiG-25 fighter and would be capable of delivering a 500 kg to 1,000 kg payload to low earth orbit at very low cost for an estimated vehicle life of 100 launches.

AVATAR is proposed to weigh only 25 tonnes in which 60 per cent of mass will be liquid hydrogen fuel. The oxygen required by the vehicle for combustion is collected from the atmosphere, thus reducing the need to carry oxygen during launch. AVATAR is said to be capable of entering into a 100-km orbit in a single stage and launching satellites weighing up to one tonne.

Operation

AVATAR RLV-TSTO

AVATAR would take off horizontally like a conventional airplane from a conventional airstrip using turbo-ramjet engines that burn air and hydrogen. Once at a cruising altitude, the vehicle would use scramjet propulsion to accelerate from Mach 4 to Mach 8. During this cruising phase, an on-board system would collect air from the atmosphere, from which liquid oxygen would be separated and stored. The liquid oxygen collected then would be used in the final flight phase when the rocket engine burns the collected liquid oxygen and the carried hydrogen to attain orbit. The vehicle would be designed to permit at least a hundred re-entries into the atmosphere.

Dr. M R Suresh, a senior ISRO official, stated that, “The dream of making a vehicle which can take off from a runway like an aircraft, and to return to the runway after deploying the spacecraft in the desired orbit (or Single-stage-to-orbit or SSTO) can be fulfilled only by the availability of more advanced high strength but low density materials so that the structural mass of the vehicle could be reduced considerably from the present levels. The advent of nano-technology could play a deciding factor in developing such exotic materials. However, the material technology available today can realize a Two Stage To Orbit (TSTO) vehicle only and the configuration of the vehicle which is being considered. However, the before realizing the RLV-TSTO it is important to perfect many critical technologies pertaining to hypersonic reentry vehicles. Hence a technology demonstrator vehicle (RLV-TD) is being developed.”

Development

AVATAR is being developed by India’s Defense Research and Development Organization. Air Commodore Raghavan Gopalaswami, former chief of Bharat Dynamics Ltd, Hyderabad, is heading the project. He coined the name and made the presentation on the space plane at the global conference on propulsion at Salt Lake City (USA) on July 10, 2001. Gopalaswami said the idea for AVATAR originated from the work published by the RAND Corporation of the United States in 1987.

AVATAR is currently in the prototype testing stage and an initial development budget of only $5 million is allocated. Along with DRDO team development of critical technology components were undertaken by as many as 23 academic institutions (Indian Institutes of Technology, Indian Institute of Science et al.) along with ISRO in India. Both the scramjet engine concept and the liquid oxygen collection process have already undergone successful tests at DRDO and at the IISC. DRDO has approved further testing of the liquid oxygen process and assigned a team to conduct a detailed review of the vehicle’s design.

Currently DRDO plans to build and fly a scaled-down version of AVATAR, weighing just 3 tonnes at takeoff. The project is headed byVikram Sarabhai Space Centre in Thiruvananthapuram. The mini AVATAR is to be built by a Hyderabad-based private company called CIM Technologies, project completion data is still not finalized. The prototype will be launched using the PSLV and will demonstrate all technologies used in AVATAR including oxygen collection. The aerodynamics characterization of the RLV-TD was done by National Aerospace Laboratories. The AVATAR design has already been patented in India and applications for registration of the design have been filed in patent offices in the United States, Germany, Russia and China.

Overview

The KALI is not a laser weapon as commonly believed. It emits powerful pulses of electrons (Relativistic Electron Beams- REB). Other components in the machine down the line convert the electron energy into EM Radiation, which can be adjusted to x-ray (as Flash X-Rays) or microwave (High Power Microwave) frequencies.

This has fueled hopes that the KALI could, one day be used in a High-Power Microwave gun, which could destroy incoming missiles and aircraft through soft-kill (destroying the electronic circuitry on the missile). However, weaponising such a system has many obstacles to overcome.

History

The KALI project was first mooted in 1985 by the then Director of the BARC, Dr. R. Chidambaram. Work on the Project began in 1989, being developed by the Accelerators & Pulse Power Division of the BARC. (Dr. Chidambaram was also the Scientific advisor the Prime Minister, and the Chairman of the Atomic Energy Commission). DRDO is also involved with this project. It was initially developed for industrial applications, although defence applications became clearer later.

The first accelerators had a power of ~0.4GW, which increased as later versions were developed. These were the KALI 80, KALI 200, KALI 1000, KALI 5000 and KALI 10000.

The KALI-5000 was commissioned for use in late 2004.

Design

The KALI series (KALI 80, KALI 200, KALI 1000, KALI 5000 and KALI 10000) of accelerators are described as “Single Shot Pulsed Gigawatt Electron Accelerators”. They are single shot devices, using water filled capacitors to build the charge energy. The discharge is in the range of 1GW. Initially starting with 0.4GW power, present accelerators are able to reach 40GW. Pulse time is about 60 ns.

The Microwave radiations emitted by the KALI-5000 are in the 3–5 GHz Range

The KALI-5000 is a pulsed accelerator of 1 MeV electron energy, 50-100 ns pulse time, 40kA Current and 40 GW Power level. The system is quite bulky as well, with the KALI-5000 weighing 10 tons, and the KALI-10000, weighing 26 tons. They are also very power hungry, and require a cooling tank of 12,000 liters of oil. Recharging time is also too long to make it a viable weapon in its present form.

Applications

The KALI has been put to various uses by the DRDO. The DRDO was involved in configuring the KALI for their use.

The X-rays emitted are being used in Ballistics research as an illuminator for ultrahigh speed photography by the Defence Ballistics Research Institute (DBRL) in Chandigarh. The Microwave emissions are used for EM Research.

The microwave-producing version of Kali has also been used by the DRDO scientists for testing the vulnerability of the electronic systems of the Light Combat Aircraft (LCA), which was then under development.

It has also helped in designing electrostatic shields to “harden” the LCA and missiles from microwave attack by the enemy as well as protecting satellites against deadly Electromagnetic Impulses (EMI) generated by nuclear weapons and other cosmic disturbances, which “fry” and destroy electronic circuits. Electronic components currently used in missiles can withstand fields of approx. 300 V/cm, while the fields in case of EMI attack reach thousands of V/cm.

As a Weapon

The KALI’s potential for a military role as a beam weapon has made it, in the eyes of China a threat. However, weaponisation of the KALI will take some time. The system is still under development, and efforts are being made to make it more compact, as well as improve its recharge time, which, at the present, makes it only a single use system.

There are also issues with creating a complete system, which would require development of many more components. There have been reports of placing the weaponized KALI in an Il-76 aircraft as an airborne defence system. There is also speculation of using the KALI as an Anti-satellite weapon and as a space-based weapon system, although it is unlikely that they would be implemented, given India’s stance on those issues.
