Wheelers Island - The testing ground for India's missiles

Wheelers Island - The base for India's missile arsenal 



A tiny island off the Orissa coast in the middle of the vast Bay of Bengal, the testing ground for Indian military might, a place which has transformed into a world class missile range complex.  The island is the base for India’s mystical ‘Integrated Guided Missile Development Program (IGMDP)’. An Island measuring around 2 kilometers in length and occupying more than 400 acres of land, the "Wheeler’s Island" is where India’s ambitious missile programs have taken course. It was in the early 1990’s that a team of leading scientists from DRDO started with the work of setting up a futuristic test range for supporting the nation’s ballistic missile program.


The team was headed by the ‘Missile of India’, APJ Abdul Kalam a distinguished scientist under whom, India’s missile program had reached newer heights. The team also consisted of the celebrated missile scientists V K Saraswat and S K Salwan. With a need for dedicated military test range, the team zeroed in on a 160 square kilometer land mass close to the Proof and Experimental Establishment (PXE) at Chandipur. But to setup a base at the desired location, the government was required to vacate nearly 130 villages with a consolidated population of well over 100000 people.



The government faced a strong opposition from the villagers to relocate from the villages and in 1995 the government decided to drop the idea of setting up a base in Chandipur and thus began the grueling search for alternative locations with very minimal habitation and far away from any traces of human establishments.  An able team led by V K Sarawat and S K Salwan was putting in charge of locating the land which be isolated but yet be easily accessible for development and logistical supplies. 


The team initially concentrated on setting up a test base at Pokran test range, which has served as an integral test range for Indian forces. But this was soon rejected considering the effect to the safety of the range. The team then began a long and grueling search for a desolate Island along the Eastern coast. DRDO then sought the help of Navy which came with hydrographic maps of the islands across the Eastern coast. The team then soon set its sight on a group of desolate islands close to ITR, Chandipur. The Islands were in fact Shoals composed mainly of washed sands, sand pebbles giving the opt environment for a test range. The six islands were spread across the vast ocean and were around 70 kilometers from Chandipur.
  

Armed with the accurate hydrograpic maps courtesy of the Indian navy and with a directional compass and minimal knowledge about the exact location of the islands, the range team comprising of S K Salwan and V K Saraswat, set off in the search of the desolate islands after hiring a fishing boat from Dhamra port. The group of Islands on the map were designated as Long Wheeler, Coconut Wheeler and Small Wheeler. The search for the islands was extremely and continued for a while until the team concluded that the islands were lost in eternity, the 'Wheeler Island' was just not traceable. It was then the team consulted the local fishermen who were accustomed to the vast ocean.  



The local fishermen, the real navigator of these turbulent seas directed the team to an island they called 'Chandrachud'. Former president ‘APJ Kalam’ has fond memory of the discovery of ‘Chandrachud’ and recalls the day saying “By the time ‘Chandrachud’ was discovered, it was late in the evening. The boatman refused to move at night and the team had to stay in the boat and spent the whole night counting the stars”. The determined efforts of the range team had paid off and but the search for ‘the Wheelers’ continued, the team then consulted the navy to reconfirm the bearings of the land-mass, the hydrographers had termed as six islands. The team was elated to know that they in fact had landed on the mysterious ‘Small Wheeler Island’.


An experienced team from DRDO then shortly began the survey of the Islands for setting up the much required and ambitious test range. The primary concern for the team was the erosion of the fine sand the island was based on, the team then forwarded the proposal of setting up a fully fledged test and research range at the islands. The government cleared the project thus paving way for India’s exclusive missile range. To avoid the concern of erosion, DRDO built a vast seawall along the island peripherals. Without a dedicated logistical solution the construction of a base was proved out to be an uphill task for the DRDO. Plans of setting up a dedicated airbase were discussed initially but were later dropped considering the hostile environment prevailing around the range. The main logistical support to the islands is the shipping lane which takes care of all the hardware required for successful completion of missions.



The island is the theatre of action for the DRDO scientists who have propelled India to new heights with the latest missiles technologies. The Wheeler base is now known an integral part of all strategic missile programs of India and also has witnessed the launch of conventional missiles. The first missile to be fired from the range is the Agni-I and Agni-II. The missile testing range has now evolved to a world class missile testing facility. The base has witnessed the development and launch of Agni I-V, Prithvi missiles, the AAD program, Nirbhay cruise missile, the mighty BrahMos, Nag Anti-tank missiles, Akash and Trishul Surface to Air Missiles (SAM).

The base has 4 Launch Complexes (LC) which serve as the nerve center for all launch campaigns mounted by DRDO. The main launch site for the strategic missiles is the LC-IV, which was established recently to test long range ICBM’s and IRBM’s. India’s ambitious interceptor program, AAD has also been test fired from the Wheelers base. The base has the latest tracking systems, the base is equipped with state-of-the-art surveillance radars. The base also employs the latest Electro-optical tracking system, S-band tracking radar, C-band tracking radar and telemetry band systems. For closely monitoring the launch programs the base has the latest range computer, meteorological systems and to attain safe launches also has the most advanced safety system.




The facility is the result of India determination to master the latest missile technology. DRDO has set a massive step forward to make India ‘Missile import free’ by 2020 and has promised to make India a leading exporter in missile technology. India today has some of the deadliest and accurate missile system in its arsenal and the ‘Wheelers base’ has been a key part of every mission. India’s most celebrated missile scientists be it, ‘The missile men of India’ “APJ Abdul Kalam”, ‘The missile women of India’ “Tessy Thomas’ or V K Saraswat have their own share of stories to be narrated about the base. India is gearing up for testing an salvo of newest missile technologies and ‘Wheelers Island’ will be the launch site, DRDO will propel India’s strategic capabilities to greater heights in the coming years.





Suggestions for the betterment of DRDO, an able organisation powering the dreams of Indian forces


  •     “The  need for advanced air defense systems”. Indian army currently deploys 2K12 ‘Kub’, 9K33 OSA, 9K35 Sterla-10, ZSu-23-4M and ZSu-23-2 air defense systems. These systems were acquired from the Russians in the late 70’s and 80’s  and are fielded in the front lines to guard against any aerial threats but these systems  have limited capabilities. Akash SAM systems promise to be a very reliable air defense system, but Akash is a missile system and air defense guns are the need of the hour. Hence DRDO should consider deploying long range air defense guns at the earliest.              


  •     “Empowering the mechanized forces of army “. Indian army’s mainstay battle tanks the T-72 lack night fighting solutions thus making them blind in the night and providing a crucial edge for the enemy. The tanks are yet to receive thermal imaging systems which can allow the tanks to be all weather and night time capable tank. The home grown Dhanush artillery guns have completed their user trials and India currently uses the aged Bofors. Thus DRDO should constitute a parallel line to ramp up production capability. India is looking forward to acquire howitzers shortly from BAE, DRDO should use this opportunity to empower our home grown artillery guns.   



  •      “A reliable assault rifle is the need of the hour for our forces “. INSAS program has been plagued by problems which have been highlighted several times. F-INSAS had promised a solution for this, but the program has been scrapped now. Private companies in collaboration with foreign players will now be developing a reliable BMS. And the forces now look forward for a weapon system that guarantees firing power and accuracy. DRDO should provide an all weather and reliable weapon for the forces.



  •   “A reliable afterburner engine for the futuristic program”. The ambitious GTRE developed GTX-35 VS Kaveri engine program has been scrapped after spending more than 2000 cr. Not just the money but the work power and the R&D involved in the project were immense and we hope this will be implemented in the futuristic projects GTRE will develop in the years to come. Can the knowledge gained when developing ‘Kaveri’ be used to develop more advanced afterburner engines for the ambitious AMCA and unmanned projects of India? Developing afterburner engines is a very demanding field and very few countries have mastered this, it would be really proud to see India on this list.


  •  “Attracting and igniting young minds”. DRDO is the key for Indian forces call for modernization. Working and developing for the nation is a dream for many but very few realize the opportunities available. India has one of the brightest and intellectual mass, if DRDO can attract the younger population R&D of the nation has a very promising future. DRDO can start a student program wherein students are selected from reputed colleges and institution. Choosing interested people right from a young age and training them in a particular field is the key. Implementing this program right at schools can bring wonders.


  •     “Impetus for a more robust missile program”. India has a very advanced missile program and the accuracy of Indian missiles is said to be one of the best in the world. PAD and AAD have proved their capability but India requires a more advanced defence shield. DRDO should fast track the development of anti-radiation missile. These missiles can disable the radar and communication facilities of the enemy. With America being vocal about India acquiring these systems, DRDO can utilize the assistance of US wherever possible. The LR-Cruise missile of India, Nirbhay has a long way to go from here. Air launched and Submarine launched version is yet to be rolled out and cruise missiles are an important part of the arsenal, DRDO should expedite the development of the Nirbhay. INS Arihant has reached its advanced test phase, with this the second strike capability of India has taken wings. But the current K-12 and K-4 have limited range. DRDO should thus constitute work on developing a robust SLBM which has an extended range of 5000+ km thus taking the second strike capability of India to new heights. Light weight torpedos are needed for the soon to be inducted submarines and thus work on this field is crucial. The BVR Astra also will be a key since our arch rivals are fielding aircraft with BVRM capability, Astra has reached it’s advanced test phase and has to be integrated on our fighters at an expedited pace.


  •      “Developing advanced eyes in the sky, radar’s”. Radars are a key part in protecting the sterility of our skies, clubbed with our air defence systems these are true nightmares for the hostile forces. DRDO has to look at indigenously developing radar’s for all the wings. India has a tie-up with ELTA and other European firms for developing more advanced radar’s.  Israel has already provided India with Greenpine radar system for AESA radars. These radars are crucial for fighter jets and have extremely low probability of intercept and high jamming resistance and thus can help in easily detecting targets in the air. DRDO should concentrate on tweaking these radars for increased range. Developing Aerostats and AWACS are crucial to keep tab of enemy activities across our borders.



  •  “Ready for tomorrow’s challenge through a futuristic approach”. India has to implement a futuristic approach for tackling hostile forces. DRDO should start implementing futuristic programs, drones and robots which can help keep tab on activities throughout the battlefield will be a key addition to the force. The UAV fleet of India is yet to evolve to its best capability, armed drones can help weed out threats effectively with no causalities. India now also has the chance to work with US on drones and this can be a game changer. DRDO has been developing battle oriented robots, these robots have been used for an array of activities. DRDO can now concentrate on notching up the work and using these robots to replace front-line forces specially for breaching buildings and counter-insurgency operations. Stealth is one more field DRDO is yet to attain hold in, with hostile nations ramping up their air defence capability a aircraft or drone invisible to the radar’s will be an added addition. 


  •     “Cyber warfare a worrying concern”. The battle’s in the future will be fought sitting in front of a console rather than the traditional weaponry warfare. Cyber warfare is an issue that has been a worrying concern for nations, the recent hacking of Defence officials is an example of the threat. Enemies sitting thousands of kilometer away can easily strike right at the heart of our nation if proper precautions and protocols aren’t in place. Even if the nation is blinded for a minute the loss is unimaginable but id the same is done to inflict damage in many fields the loss may exponentially multiply. Thus an advanced cyber warfare authority is the need of the hour.


  • “The best working environment at DRDO”. Lastly coming to the DRDO itself. We all have heard the amount of work that goes behind every single project. The amount of R&D, innovation and dedication put in to a project is immense. It is crucial that the work environment at DRDO itself is maintained at its best.  The employees have to be actively involved in HR development and self development programs. The government should also concentrate on providing the employees with the best possible amenities that can always guarantee a secured and fulfilling work environment. DRDO should also concentrate on identifying the best workers of the lot and awarding them timely, this will not help the individual work more aggressively but will also cultivate a positive race within the organization thus igniting minds and taking the reach of the organization to newer heights. 

The cruise missile arsenal of India

BrahMos and Nirbhay cruise missiles - Striking the enemy at their hearts 


As the name defines these missiles basically cruise to deliver their payload to a designated target and decimate the intended target. Cruise missiles are usually powered by jet engine, Scramjet and Ramjet being the latest technology. Cruise missiles are extremely cost effective and clubbed with its speed and unique capabilities can cause havoc our enemy territory. The unique capability of the cruise missiles is its ability to employ low hugging trajectory and terrain hugging abilities thus making it extremely difficult to be detected. Cruise missiles are classified based on the speed they can attain during the powered phase of the flight, subsonic cruise missiles travel at a speed lesser than the speed of sound approximately at around 0.8 mach. Subsonic cruise missiles are the most cost effective delivery system with ‘Tomahawk and Klub’ being the best examples.

Supersonic missiles travel approximately at around 2-3 mach i.e. covers almost a kilometer/second during its powered phase of the flight. BrahMos jointly developed by India and Russia is the only versatile Supersonic cruise missile. Even though other cruise missile systems attain supersonic speeds it is restricted only to the terminal phase of the flight. Medium range cruise missiles are preferred over long range missiles, owing to the operational cost.  Hypersonic missiles are still under development and can attain speeds up to 5-6 mach. Incidentally BrahMos Aerospace will be fielding its BrahMos – II, a hypersonic cruise missile capable of attaining speeds up to 7 mach by 2017.   

 
BrahMos - The fastest cruise missile


India has the fastest and the deadliest cruise missile in its arsenal, BrahMos. BrahMos jointly developed by India and Russia is currently the fastest cruise missile in service. BrahMos Aerospace a private company which works independently off the political circles was setup by India and Russia to develop the most reliable delivery systems. BrahMos is a portmanteau of the rivers Indian and Russian rivers Brahmaputra and Moskva. The ‘missile man’ of India APJ Abdul Kalam and the then Russian deputy defense minister N V Mikhailov were instrumental in conceiving BrahMos and worked relentlessly to forge a reliable space for the joint development of latest aerospace technologies.



A joint venture was signed between Defence Research and Development Organisation (DRDO) and Russia NPO Mashinostroyenia. The project took baby steps with India securing 50.5 % share and Russia holding 49.5% share, and the company was finally setup through an Inter-Governmental agreement at Delhi on 12th February 1998. Russian government and Indian government pitched in US $123 and US $127 million respectively for the project. The aim was to develop a deadly medium-range strike missile that would feature superior stealth and delivery systems compared to the western missile systems. After working out key details BrahMos was decided to be developed around Russia’s proven Oniks system.

DRDO and NPOM worked closely to freeze a technologically advanced missile system and to effectively cut the cost throughout the process to reduce the burden on both the states. DRDO developed state-of-the-art navigational systems, mission software’s and mobile launchers for the missile system. NPOM started development of Ramjet engine which could power the system to supersonic speeds. In the October, 1999 BrahMos Aerospace came out with a two stage missile system powered by ramjet engine. With Russia being a signatory to the MTCR the range of the missile was restricted to 290 Km.

The Ramjet engine of the missile is powered by NPOM developed a two stage engine. The first stage of the engine is powered by solid propellant and the first stage propels the missile to supersonic speeds and during the cruise phase the second stage by powered by a liquid propellant kicks in helping the missile attains speed up to 3 mach making it the fastest cruise missile in the world. The missile can carry conventional warheads weighing 300 kg. The missile’s strike capability is enhanced due to the enormous kinetic energy it packs which is multiplied by its speed and weight.

BrahMos was test fired from Integrated Test Range (ITR), Chandipur on 12th June 2001 in VTL configuration. Repeated configuration and validation tests followed over the course of ten years, the missile system evolved with every test. BrahMos was fired from INS Ranvir in VTL configuration on 18th December 2008. The missile was thus successfully launched from two of its planned platforms and was then cleared for user trials by Indian forces. In 2010 Indian Army and Indian navy started their user configuration and validation tests and the system was tested without any hindrance in a campaign that lasted for almost two months. It was during this campaign BrahMos attained an astonishing 3.2 mach velocity thus becoming the fastest cruise missile in terminal phases.   

The development and success with BrahMos has been a never ending process, the missile has evolved over the years and is now currently in Block III configuration. Till date 35 validation and configuration tests have been carried out. The BrahMos team attained another milestone when the Submarine-launched version was fired from a submerged pontoon from off the Visakhapatnam. BrahMos-A the air launched version is expected to be test fired shortly from an IAF Su-30. Two Su-30 haven been refurbished by Sukhoi for carrying the missile, the system will be 2-3 meters shorter compared to the conventional missile and has been developed with special materials to drastically reduce the weight of the system. BrahMos – M a smaller variant of the BrahMos – A is also being designed to be fired from other jets. BrahMos has made head way in developing BrahMos – II, a hypersonic missile system which is slated to be test fired by 2018.

Indian navy has deployed BrahMos on its destroyers and frigates. The latest Kolkata and Visakhapatnam class destroyers have been equipped with two 8-cell BrahMos launchers which can house the land attack and anti ship variants.  Frigates have been armed with land attack BrahMos VLS systems. The army has deployed four regiments of the BrahMos and each regiment contains about six launch batteries and at least 90 missiles. Indian Air Force (IAF) has placed an order for 200 air launched version of the BrahMos.

 Nirbhay – Made in India


The home grown Nirbhay, is a multi-platform all weather cruise missile. The missile can carry a maximum payload of one tonne and can strike targets up to 1000 km. Nirbhay is a two-stage missile system with loitering capability. Equipped with the state-of-the-art ring-laser gyroscope the missile has pin point accuracy and can strike targets minimal collateral damages. Nirbhay is also capable of flying at extremely low altitude and with its terrain hugging technology the missile can fly at tree levels thus avoiding any contact with radar systems. This helps in reducing the reaction time of the enemies.

The first stage of Nirbhay is powered by a ramjet engine which propels the missile to high altitude and the second stage is powered by a gas turbine engine which helps in attaining better maneuverability at the  terminal powered phase of the flight. Once the missile attains its cruise phase the missile is powered by the gas turbines and winglets which help in maneuvering and strike the designated target.  The missile is based on fire and forget system which cannot be jammed by any of the latest systems. Powered by a gas turbine engine and the winglet the missile has the unique capability of hovering over the target just before striking. The missile is equipped with inertial guidance system which relies on ISRO's IRNSS satellite system.

Nirbhay is capable of carrying both nuclear and conventional warheads. Initially Nirbhay will be launched from a mobile launcher which has been developed by Tata. Further development will guarantee the launch of Nirbhay from Aerial and Naval platforms. The missile will supplement BrahMos with its extended range. The first test of the missile took place in February 2013, the test was a partial success as the missile was destroyed half way to its target after it showed diversion in its trajectory. The missile was again tested in October 2014, the missile delivered the package to the designated target flying flawlessly through the skies. Nirbhay is expected to enter service in less than three years. India also has the Exocet and Harpoon missiles in its arsenal.
