    Why Tejas Mk2 (MWF) Will Be Important

    Written by: Vipul Dave
    Date: February 12, 2019


    Indian CRPF convoy hit by Pakistan trained terrorist with huge explosive killing more than 40 Jawans. India warned retaliation and preparation of air raid begun. India struck LET terrorist camp with laser guided bombs and eliminated hundreds of Terrorists, their trainers, ISI people and Pakistani Military officers and JEM commanders including family members of JEM chief Masood Azahar. .

    Once again Indian Airforce Choose 4 decade old Mirage 2000 for the mission inspite of having state of art planes like Sukhoi MKIs, Mig 29 etc. This shows how important the plane is. It is very much relevant even today with upgrades in electronic inspite of new fighters entering the service. India used the same plane in bombing Kargil height inspite of having MKIs, Jaguars and Mig 29s. This shows How important the plane is.

    The question here is what makes Mirage 2000 so special. Why it is a weapon of Choice of Indian army even after 4 decades. What after Mirage 2000 and its substitute once Mirage 2000 retires. These questions needs consideration.

    Mirage 2000 is a medium weight fighter with Maximum takeoff weight of over 17 tons and payload of over 5 tons. It is upgraded with state of art electronics and one of the best BVR Mica. It has a high Instantaneous turn rate to fire missile first in case of conflict. It has a highly reliable engine and top speed in excess of Mach 1.8. All this makes it a weapon of choice for Indian air force. Now what next after Mirage 2000?

    Actually, when India floated a tender of MMRCA tender, they wanted something like Mirage 2000 . When India made Tejas, India wanted to build something like Mirage 2000 and they build in many qualities of Mirage 2000 in Tejas. However, Tejas, because of its small size and comparatively low powered engine could not become a MMRCA like Mirage 2000 and Indian air force wanted something bigger and better. HAL and DRDO offered Tejas Mk2 with higher thrust engine and bigger in size Tejas Mk2. After many speculations published and contradictory reports surfaced, Tejas Mk2’s design was finally revealed before Aero India 2019. It is a highly impressive design meeting so many requirements of Medium Multi Role Combat Aircraft (MMRCA).

    [​IMG]

    Design and Specification:

    Tejas Mk2 also known as Medium Weight Fighter (MWF) looks very much similar to Tejas Mk1. However the main differences are prolonged fuselage. The overall length of Tejas Mk2 is 14.7 meter from increased from 13.2 meter in Tejas Mk1. While studying the aerodynamics and its constrains in Tejas Mk1, it was observed that it was unable to comply to Area ruling because of short length. So it was decided to take care of this concern of Tejas Mk1 by increasing the length. Other aerodynamic issues such as elevating canopy, redesigning pylon, putting short range missile on wing tip etc is freezed in Mk2 design. All this will reduce aerodynamic drag and will improve transonic acceleration by a very good margin.

    The constrains of limited seven hand points in Mk1 is addressed very satisfactorily by providing 11 hand points . The payload of 3.8 tons is increased to 6.5 tons. All concerns of Mk1 are not only addressed but user Indian air force's expectations are surpassed.

    Another noticeable change is addition of canards for handling at low speed and short take off etc. In my opinion, these changes are made so that designers may not have to work very hard on naval LCA Mk2 and Air force MWF may relatively easily be converted into naval Tejas Mk2.

    Another big issue which is addressed is increasing fuel capacity from 2.5 tons to 3.3 ton which will give it a big boost in ferry range and combat radios. Supersonic fuel tanks are also developed. It offers a big fuel capacity with minimum addition of drag. This will further add to range and mission capability to carry out operation in large geographical area.

    The another most important change will be the replacement of current GE 404 engine with higher power GE 414 IN6 engine. Tejas Mk2 will have GE 414 IN6 engine with some 60 KN + dry and 98 KN wet thrust engine which will give Tejas Mk2 and ability to carry more load and faster speed. It will be a fully home grown plane with American engine which may be replaced by K10 in future.

    Tejas Mk2 is not a stealth but it is designed for very Low RCS. Its “Y” duct intake conceals engine totally. There has been a lots of simulation to put canard on right place. External body in now more than 90% made of composite material giving it low weight low RCS and low weight. RAM paint developed for AMCA shall find its application in TEJAS Mk2 to further add to its stealth character.

    After building huge inventory of heavy category fighter like SU 30 MKI and developing light weight Tejas MK1, Entire focus of India is now centered on acquiring medium weight fighter like Rafale or other MMRCA. Tejas Mk2 is a surprising sweet option which has emerged for Indian air force.

    Radar, Infrared track and search system and electronic warfare:

    This area is also got a big boost. New Uttam AESA radar will have much higher range than current MMR and it will virtually be Jam proof. It will replace Israeli ELTA 2052 radar in Tejas Mk2. BEL has started work on development of Infrared track and search system which will go into Tejas Mk2. This will give Tejas a great capability to see enemy even without putting its AESA radar on to keep its presence secrete. An Israeli company is already short listed to co-develop electronic warfare suite. Same suite for Mig 29 is already been developed. Development of EW suite for Tejas Mk2 is unlikely to face any challenge. Missile approach warning system is already been developed which will go into Mk2. Sensor fusion is a gray area and yet much clarification has not come.

    Weapons:

    Tejas Mk2 will come with huge weapon load of 6.5 tons. Designers have already surpassed all expectation of IAF by providing 11 hand points and some of them may be used with multiple hangers carrying two missile of each one. This is a combination of huge payload and huge number of hand point will give this plane an extraordinary flexibility to carry any sort of mission with missiles or bombs and strike a target far away.

    During exercise Gagan Shakti, Tejas proved its ability to bomb targets with high Precision. Bombing and its accuracy is already been proved and it is a proven capability of Tejas Mk1 which will go into Tejas Mk2. It has Impressed Indian air force winning lots of admiration from senior IAF officers. India has already developed glide bomb of 100 KM range with which enemy positions can be attacked from far away. India’s own smart area airfield weapon can strike runways from 100 km away and make runways useless.

    R 73 and derby missiles are already tested from Tejas Mk1. Python was also tested from Tejas Mk1 but it was found a bit unsuitable. Home grown Astra Mk1 with 80 KM range is already been tested and integrated with Sukhoi 30 MKI. This will go into Mk1 as well as Mk2. There are in talks with France to integrate Meteor with Tejas. France is ready to do that provided the Radar is Indian and not Israeli. With arrival of desi Uttam AESA radar, the way to integrate Meteor will clear. Meanwhile India has done few successful tests of her indigenous solid fuel duct ramjet engine missile which will have about 130 to 150 KM rage some 30 KM lesser than meteor. If either of the two goes into Tejas Mk2, they will be more than a match for enemies of India for decades to come. Meanwhile Israel has offered I derby, the upgraded version of Debby. India is already using Mica of France on Mirage 2000. So India has a great flexibility and multiple options to integrate missile and other weapons on Tejas Mk2 like no other nation has with options of Russian, Israeli, European, French and Indian weapons.

    DRDO has already tested anti-radiation missile with more than 100 KM range so as SAAW. This will give Tejas MK2 an additional punch which its competitors are lacking. Tejas will have enviously high weapon choices not available to any of the plane of its class. It will simply outsmart any other plane in the area of weapons.

    BVR and WVR engagements:

    Tejas with more powerful engine, improved aerodynamic will be much faster though not as fast as Russian planes like Sukhoi 30, Sukhoi 57 and Mig 29 but will outmatch most and its competitors and match F 16 in speed. With low wing loading and higher thrust to weight ratio, Tejas Mk2 will be a great dog fighter which will outmatch all its competitors including F 16 exclusive of Chinese Sukhoi 30s and Sukhoi 35s. However, here is a catch. Tejas with a very small frontal RCS of 0.1 Sq m to 0.2 Sq. meter and top class AESAS radar will see them first and will shoot them with either Meteor, SFDR, Atsra or derby which are very long range missiles.

    Against its Pakistani counterparts like JF 17 block 3 or F16, Tejas Mk2 will be more than a match. With very low Frontal RCS and powerful Radar like either ELTA 2052 or Uttam, it will be able to see these planes more than 100 KM away which shall be atleast 30 KH higher than those planes can see Tejas Mk2 even with AESA radar Installed on them. Tejas Mk2 will lock and shoot JF 17 or F 16 from a distance of more than 120 KM either with METERO or India’s own Solid fuel duct ramjet missile with ultra-long range. With state of art infrared track search system, Tejas Mk2 will be able to track these planes even without using its AESA radars.

    In within visible range face off, Tejas Mk2 will easily be able to defeat F 16 with higher T/W ratio, Low wing loading and Canard combo which will give it a great maneuverability. It will have no problem in shooting down F 16 with R 73. Even Mig 21 did it recently. JF 17 does not count and it is futile to compare both the planes.

    Conclusion:

    Tejas Mk2 is an upgraded version of Tejas MK1 . All shortcomings of Tejas Mk1 are addresses in Tejas Mk2. It will have a very high ferry range, combat radios and a very decent payload. It is designed for High maneuverability unlike some bomb trucks. Tejas Mk2 can do 9/-3.5 g with high AOA. It will have the option to integrate ultra-long range missiles such as METEOR and home grown SFDR . With AESA and ultra long range missile combo, it will have first shoot capability against virtually all planes except few like F 22, F 35 and will match Gripen, Rafale and EFT. This will be a most suitable plane for most of the missions like air raid, BVR combat, Close combat, Close air support, Ground attack etc. With light weight, better aerodynamic, top class weapon and great ground attack capability, this plane will undoubtedly pack a big punch in a single machine. Though this is a single engine plane, it will have the capability of being MMRCA and it will match and even surpass the capability of some contenders of MMRCA like F 16, Mig 35 and Gripen C/D and will match Gripen E in capability. So this is a desi MMRCA at low cost.

    Indian airforce which has a great passion for foreign plane has found a new love for this plane in recent time after Tejas Mk1 got FOC. They are ordering Tejas Mk1 in big numbers who used to refuse to consider an order beyond 40. Now they are planning 123 Tejas Mk1 and planning to induct more than 200 Tejas Mk2. Indian navy is also seriously considering to induct Tejas Mk2 with more powerful engine which we shall discuss some in future. The reason is that the capability offered by Tejas Mk2 is irresistible. Tejas Mk2 is a true multirole fighter which has satisfied and surpassed all expectations of Indian air force’s medium weight fighter plane at a very reasonable cost. It has won the heart and mind of Indian air force and Indian air force is unable to resist the capability it has offered.

    I genuinely hope we get tejas mk2 and Amca on time and it reaches a satisfactory level of technology, the other key is how quickly can we develop k10 engine, though I would also like hal to work on a fifth gen light weight fighter.

    The philosophy behind MWF is to build a better Mirage. It should do all which mirage does and more.

    I'm wondering if its better to that MWF is a variant of LCA or MWF is developed from LCA.
    Mk1 & 1A are more of light interceptors and ground attack aircrafts like Gripen or Jaguar while Mk2 is more of a fighter like F-16, J10B or Mirage 2000.
    I guess MWF Tejas Mk2 should have a separate page on Wikipedia. Should it?

    One word response is never helpful.

    Could you elaborate for yes or no?

    This can be achieved if HAL delegate FOC version production lines to private sector while concentrate its energies on MK2 development. They can't be Jack of all trades. They need to involve private sector in big way.

    we are behind from china & we have to do something , hal & drdo are not performing up-to level. i think we should take few planes from fgffa doesn't matter they are how much good or not and increase our AMCA speed we need result .

    IAF need 5 gen planes at right time , we dont have time for HAL experiments or researches , they have to perform otherwise govt will dis mental them .

    IAF & NAVY need numbers & quality at right time .

    of topic :: but our hyper sonic missile program is also getting late

    Not a long time ago (in 2013) an article quoting an American Expert appeared in some magazine under title " India missile arsenal is having DUD missiles". In a short period of time we operationalized and inducted many state of art missiles with very advance technology. The path India took is totally different from the path took by china. Instead of copying and producing substandard weapons, India took a long and tiresome way of developing research facility and design weapons suitable for Indian conditions. We developed Tejas after a long hard work after many failures and criticism. Finally it succeeded in impressing Indian air force. Not only Airforce is now more than willing to induct it, Indian airforce has now developed a great interest in MWF as well.
    We can not simply compare ourselves with china like many people do.
    Kota Harinarayan had rightly said that Tejas is an advance plane and China can not make a similar one.
    Tejas Mk2 will come with lots of goodies which are available in some leading planes of the world such as Rafale, Gripen, EFT etc like IRST, AESA, highly advance EW suite, top class missiles etc. Now china will say that they too have developed it much ahead but their all systems are substandard not capable of giving the required performance. We show that in air raid. Chinese Radars and air defense systems could not stop Indian air raid.
    One can not have the Idea of plane simply seeing them flying. Only war decides how good they are. Just wait for few more years and you will see that India has surged much ahead of China and many other countries.

    My question is about india security and safety & yes till now we are not giving our focus to our defence . ok i will buy your all arguments but tell me and see how capable we are for 2 front policy right now .

    I am not against the R&D but on the name of R&D can we put our safety on risk . No we cant we need 5th gen planes within 3 to 5 years , as you know china has already inducted J20,SU35,S 400 & We are just following.

    What will be answer for them .

    We should buy few planes from fgfa & rest from our own AMCA we need something to counter china.
    China is working on hyper-sonic missile while our bramosh -2 joint venture with Russia is not taking place.


    Our iaf need seriously some advance war planes to counter su35, j20 .


    Think about future & act now .
