    The Second Foundation

    The first pic shows that the inboard pylons don't support AAMs. That means the max number BVRAAMs that the Tejas can carry is two. That seems incorrect but I have no information otherwise.

    The second pic shows a dual rack for the outer pylon but I thought the outer pylon was rated for 150kg.

    Uttam AESA integrated with an LSP bird and tested on ground. Will go into flight testing into coming months.

    Initial performance comparable to Elta 2032.
    Looking forward.
    that performance roughly translates to range of 65-76 km (based on available materials on EL-M-2032) and pretty much the performance of Kopyo on Bison. im curious if anyone doing module counting on Uttam yet X3. I assume some 400-500 TRM's

    Uttam and hopefully indigenous engine would be the great step on Indian aviation industry.

    TRMs counting is just a little part of the game. incoming signal treatment is -at least- as important (aswell as TRMs in itself, power, cooling power etc.)

    We have already built and integrated a twin rack to carry the Derby - that was integrated into the Sea Harrier upgrade. A variant of that I think will be used in the Tejas to enable it to carry 4 BVRs.

    Thanks for the update sir.
    Are any pictures available sir of this dual rack?

    And can you pls ask your sources in the Navy about the status MiG-29 that aborted takeoff and caught fire at INS Hansa?
    Is it being repaired and brought to flight worthy status or is it a total write off?

    Interview with ADA Director Dr Girish Deodhare, Aeromag magazine from DefExpo 2018

    Tejas Mk1 being readied for Air to Air Refueling contact and fuel transfer trials. FOC expected by July 2018. Also confirmed that Tejas Mk2 is in the works and will be a bigger and heavier jet with more payload, fuel as well as improved aerodynamics.

    The Light Combat Aircraft Tejas is all set to commence its Air-to-Air Refuelling (AAR) flight trials. Aeronautical Development Agency has been carrying out various tests regarding the AAR for the past few months which have been successful. But, the process is a challenging one, and hence, it is very much important to make it flawless. All the simulated ground tests have been successfully completed as Tejas was refuelled by placing it at various attitudes. The technical integration for AAR has been
    completed and the trials were commenced on the ground. We expect to make Tejas ready for air-to-air refuelling by the end of April. Once Tejas achieves the operational aerial refuelling it will help the fighter to extend its flight duration considerably, says Dr. Girish S Deodhare, Programme Director (Combat Aircraft) and Director, Aeronautical Development Agency (ADA). Dr. Deodhare speaks with Aeromag about the latest updates on the LCA programme.

    -Could you share the latest developments on the LCA Tejas programme?

    The LCA Tejas programme is having a very fast progression. Currently, we are focusing on increasing the flying rate of the Mk1 aircraft to 60 flights every month. We expect to get the Final Operational Clearance (FOC) for the Mk 1 by June-July 2018.

    Most of the tasks for the FOC are in the final stage and the rest will be completed soon. Some of the tasks under focus are the completion of integration of all FOC weapons including flight envelope expansion with the Derby BVR missiles. The software fine tuning for complete carefree manoeuvring is also in progress.
    Hindustan Aeronautics Limited (HAL) and ADA are working together to speed up the FOC activities. The experienced IAF/ IN pilots of National Flight Test Centre (NFTC), who have been involved in flight testing the aircraft from day one, are continuously improving the flight capabilities with their inputs and suggestions.

    Another important task we are working on now is the Air-to-Air Refuelling (AAR) of Tejas. We have been carrying out various tests regarding the AAR for the past few months and have been successful. But, the process is a challenging one, and hence, it is important to make it flawless. The technical integration for AAR has been completed and the trials have been commenced on the ground after initial carriage flight trials. All the simulated ground tests have been successfully completed as Tejas was refuelled by placing it at various attitudes on the ground. This was to monitor the pressure at which the fuel is pumped into the aircraft. The aerial refuelling must be done without taking much time. We are very much careful about even minute things that should be considered during the process. We expect to make Tejas ready for air-to-air refuelling by the end of April.
    Once Tejas achieves the operational aerial refuelling capability, it will help the fighter to extend its flight duration and endurance considerably.

    Last year in December, HAL has confirmed the order of 83 aircrafts of Mk 1A configuration in addition to the earlier 40 aircrafts. From the 124th aircraft onwards, LCA Mk II will enter service. It will be a bigger aircraft with a higher capacity engine, higher range and payload capacity, improved aerodynamics etc. The Mk II project is in the detail design stage. We have received the approval to prove unmanned technologies like auto take-off and landing on LCA for future uses. The unmanned version will sport Flush Air Data Systems technology for stealth feature. The design of the front also will be modified. The project will begin immediately after receiving the FOC for Mark 1.

    -Could you elaborate on the plans to upgrade the weapons capability and advanced technologies of LCA Tejas? What is the future roadmap for LCA Tejas?

    We are planning to enhance the combat capabilities of the Mk 1A by integrating new weapons. Tejas has already completed precision bombing with laser-guided 1,000lb bombs and unguided bombs. The integration of Rafael’s Derby fire-and-forget missile will be completed soon, and it will serve as the Tejas’ initial medium range air-to-air armament. The integration of Active Electronically Scanning Array (AESA) radar is underway, and it is expected to be done soon. The AESA radar will improve air-to-air superiority and strike missions and to achieve long detection ranges and multi-target tracking capabilities. The Mk II is being designed to sport an array of upgraded weapons system along with all sensors and will be capable of carrying all futuristic indigenous weapons. The major thrust of the aircraft will be its ability to carry missiles like Astra and BrahMos. It will have Software Defined Radios (SDR) and all equipment to wage electronic warfare. The Mark II will be much superior in terms of its combat capabilities and will belong to the Medium weight class.

    -Kindly share your thoughts on increasing the annual production of LCA Tejas to meet the requirements of IAF.

    ADA is helping HAL in every possible way to increase the production of LCA Tejas. In fact, we conduct coordination meetings every day to discuss on accelerating the project and secure the FOC at the earliest. Meetings are also held with members of LCA Squadron to get suggestions from them regarding what should be improved in terms of design. HAL has opened its new assembly line and it will increase the rate of production.

    In the case of MK II, it will be easier for HAL to manufacture it as ADA is making a production-friendly design for the aircraft. We are leveraging the experience got from the Mk 1 and Mk 1A. Now, the designers are familiar with the production processes and they know its challenges. Hence, we are focusing on a design for manufacture for the Mk II. Also, it will make the maintenance process easy.

    -Are there any further plans to promote the Make in India programme of the Central Government through the absolute indigenisation of more vital components of Tejas?

    The indigenisation of the components of LCA Tejas is one the major thrusts at present. The production of Tejas is closely on the line of promoting the government’s Make in India programme. Initially, the idea was to develop a new light combat aircraft indigenously to prove the technology. Hence, in the beginning we had to rely mostly on proven imported components. But now, more than 60% of the LRUs of Tejas are indigenously made. We are also aggressively encouraging the vendors/developers who are ready to take up the development of the components. For the Mk II, we will provide completely upgraded Flight Control Systems, avionics, sensors etc. of which the indigenous development has already started.

    -Tejas is acclaimed as the lightest and smallest multi-role supersonic fighter aircraft. How does Tejas outweigh its rivals in this segment?

    LCA Tejas is the smallest and lightest Multi- Role Supersonic Fighter Aircraft of its class. This highly manoeuvrable combat aircraft is designed for specific roles. Tejas is often compared to JAS 39 Gripen of Sweden, Pakistan’s JF-17 Thunder etc. Every aircraft is built for a specific purpose. Hence, it is not easy to compare them with each other and reach on a conclusion on the better one. But, taking into consideration Tejas’s far superiority in terms of avionics, digital flight control systems, advanced digital cockpit and manoeuvrability, it is competitive enough to lock horns with any of the multirole aircrafts in its class.

    -During the recent visit to India, Singapore’s defence minister Ng Eng Hen has flown Light Combat Aircraft Tejas and called it an “impressive flight”. How do you assess this achievement of Tejas regarding its export plans?

    It was a prestigious moment for LCA Tejas. Ng Eng, The Defence Minister of Singapore, who took a half-an-hour flight in the rear cockpit of fighter in the skies of Kalaikunda airbase in West Bengal, has become the first civilian foreigner to fly Tejas. Two Tejas aircrafts were flown in from Bengaluru to Kalaikunda airbase for displaying them to the Singapore Defence Minister and he was ready to go on a sortie in Tejas. The IAF was completely confident about Tejas’ safety and capabilities, and it has promoted Tejas’s image. Many countries like Singapore, Sri Lanka, Turkmenistan have shown interest in Tejas. Singapore has come forward to show interest in the trainer version of Tejas for training purpose of air force personnel.

    -The Naval Version of LCA for operation from Aircraft Carriers has successfully completed its test flight. What are the latest updates on this project?

    The naval version of Tejas has completely mastered the ski jump, take-off from aircraft carriers, even at night time also. But, the arrested landing of the aircraft is still a challenge to be overcome. The hook for the arrested landing has been integrated and we are now progressing towards demonstration of arrested landing. We expect to prove Carrier Compatibility of Tejas by the end of the year.

    -Kindly shed more light onto the Advanced Medium Combat Aircraft project of ADA.

    The Advanced Medium Combat Aircraft (AMCA) is a 5th generation fighter concept. The feasibility study of the AMCA has been completed and a feasible configuration has been evolved. The design of AMCA will meet the requirements specified by the IAF. The AMCA will feature a twin-engine and single seat layout. It will have inherent stealth mode and will be able to carry advanced weapons. Initially it is planned to build two Next Generation Technology Demonstrators (NGTD). These will leverage the existing technology of the LCA to achieve the target of first flight within five years.

    -What are the vision, goals and priorities you have set for the Aeronautical Development Agency (ADA) during your term as the Director? What are the new initiatives?

    These are exciting times for aerospace industry. ADA is fully confident about developing the optimal design for aircrafts that will bolster the Indian defence sector.

    When we started the LCA programme the most often heard question was “Can you make an aircraft?”. But, we have proved the capabilities by presenting a fully operational LCA Tejas. Now the question is “How long will it take to make an aircraft?”. We are backing the HAL in the production of Tejas by providing maintenance-friendly design and essential upgradations.

    Our focus is currently on the LCA Mark II, along with giving equal importance to the production of Mark 1A. The development of AMCA is another priority.
    A lot of youngsters have joined ADA’s design team. We are focusing on transferring the rich experience of our senior designers to the younger generation to make them capable to take up the projects efficiently in future. ADA is also promoting the involvement of women scientists and more than 40% of the designers are women. The government policies are giving a huge impetus to aerospace industry in India. With the support of the government, we are confident to take the industry to further heights.

    IAF pushes for faster production of Tejas after Exercise Gagan Shakti

    The Indian Air Force’s pan-India exercise Gagan Shakti-2018, for practising war-time drills witnessed the IAF pushing the limits of its every fighter aircraft, including the Tejas, which entailed conducting six sorties per day on all of them, totalling to about 9,000 sorties.

    For the Tejas, this is a good development as the IAF usually sticks to around three sorties per day on every Tejas. However, the Tejas was not without problems and had developed snags during the exercise, top IAF officials said on Tuesday. Nevertheless, the IAF has expressed happiness with the performance of the Tejas Light Combat Aircraft (LCA) and is looking towards faster production of them, explained the officials.

    A senior IAF official dealing with Gagan Shakti, which was conducted between April 8 and 22, explained that fighter aircraft, including the Tejas, Sukhoi-30 and MiG-29, undertook ‘surge operations’. These operations mean generating maximum number of sorties in a 24-hours cycle. “We have carried out our trials and we will be able to generate six sorties per Tejas per day for all the eight Tejas,” said the official, adding that these number of sorties were conducted on every Tejas during the exercise. The six sorties per day for the fighters was done on days when it didn’t have missions such as long distance. The Tejas was used during the exercise to check its efficiency in operations such as ground attack and other strike missions. “We are happy with the performance of the Tejas and are looking forward to the faster production of them,” said another senior official.

    The Tejas, however, also faced different types of snags during the exercise. “These were routine snags. But we were able to recover from the snags we encountered. They didn’t affect the operation of the Tejas,” said an officia,l adding that the snags were not a nagging problem. The exercise was a major employment of the Tejas by the IAF, which conducted more than 11,000 sorties on over 1100 aircraft, including combat, transport and helicopters. Out of this, 9,000 sorties were conducted by fighter aircraft. “This was a peacetime exercise and we generated large number of sorties. During war, we will generate higher number of sorties than what we did during the exercise,” said an official.

    This is the state despite the IAF having only 31 fighter squadrons when it needs 42 to tackle the collusive threat of Pakistan and China. It conducted offensive and defensive operations along both the western and eastern fronts. “We tried to maximise what we can do with our current capability,” said an official, adding that with more number of fighters the IAF’s capabilities will rise. The IAF, earlier this month, had issued a Request for Information, stating its intent to procure 110 new fighters. Officials added that the high serviceability (80%) of the aircraft was possible during the exercise due to a dedicated maintenance team. “The Air Headquarters was also monitoring the situation and we had people checking from where spares can be made available. So we ensured that the aircraft serviceability didn’t go down,” explained an official. “The logistics stamina of the IAF and the ability to sustain continuous operations through day and night was put through a rigorous assessment,” said another official.
    This is the kind of media we have. Pathetic.

    Tejas entered service a year ago, there are just 8 in service, obviously there will be some initial teething troubles. But the media is trying to dig and find some sensational story about how the Tejas developed snags (as though other jets don't). The IAF is happy with the jet, wants more to be inducted quickly, but the talk is about "snags".

    They won't talk much about how it is participating in such a large scale exercise for the very first time, what missions it carried out, how it generated 6 sorties in a day, showing that its turn-around time is as good as any other fighter that has been in service longer and had its kinks ironed out.
