    We will be lucky if the LCA can carry 1 twin arm for ECM pod and a missile.

    LCA Tejas absolutely on right trajectory and getting better

    Basic functionality to understand, Tejas was / is built to replace Mig-21 for point defence and interception purposes. Not as an forward strike force or deep strike force fighter.

    Coming on to the fact that will Tejas be obsolete by the time Mk.2 enters service ? Answer is NO. Even though Raptors entered service with USAF has U.S. replaced its entire fleet of 4th Generation Planes with Raptors ? NO. F-15 & F-16 are still getting much needed upgrades and life of F-16 is extended upto 2048.

    Even though Russia has developed PAK-FA why are they inducting more Su-35’s ?

    It is a fact that IAF is suffering from a depleting squadron strength as Mig-21 and Mig-27 are retired and Mig-29 and Jaguars will also retire by end of next decade. To keep up the squadron strength, India has now Su-30s coupled with Rafales and next IAF will have AMCA and Su-57. Tejas will also fit in this role, but it does not mean that it is a less potent aircraft and is inducted only to keep a numerical strength.

    Tejas was built to replace Mig-21 for point defence and interception purposes so it does not necessarily becomes obsolete as fifth generation fighters have entered service. India is actively working on fifth generation projects like PAK-FA and AMCA which will hopefully enter Indian service by 2030.

    Tejas is also developed by keeping adversaries at bay. Now no PAF aircraft except F-16 Bk.52 is as technologically advanced and potent as Tejas Mk.1 & Mk.1A. The newer F-16 Bk.52 with PAF is as advanced as Tejas while Tejas edges out the older F-16 Bk.30 of PAF which is being upgraded now. Leaving that PAF operates now obsolete upgraded Mirages , technologically inferior JF-17 and F-7 ( Chinese Mig-21 )


    The Latest updates of Tejas MK2 is in good mode and on speed track ::

    - Avionics architecture has been finalized.
    - New cockpit with bigger size (6”x8”) displays designs completed.
    - Configuration of Active Phased Array based Unified Electronic Warfare Suite (UEWS) finalized
    - The number of elements that can be incorporated with the existing geometry for the Antenna Array unit of AESA Radar has been finalized and performance parameters like range and Effective Radiated Power (ERP) computed.
    - Night Vision Goggle (NVG) compatible L E D lights for Navigation lights and Taxi / Landing Lights are being developed. -
    Engineering models have been developed. Performance is being evaluated.
    - Conformal antenna developed for V/UHF
    - Unified Pylon Interface Computer (UPIC) fixed in place of individual Pylon Interface Boxes
    - GE-F414 engine for LCA AF Mk2 and a contract was signed with GE, USA in September 2012 and due for delivery by 2019.
    - Canopy reshaping, outer cowl modification, actuator fairing extension and supersonic pylons have resulted in approx 20 counts (8%) drag reduction in supersonic regimes.


    Trials to offload one hydraulic system to reduce the load on JFS during starting completed. This will help in cold weather high altitude operations.

    Liquid Cooling System configurations, separate for Uttam AESA and UEWS have been finalized. However not sure if Mk.2 still will have Uttam radar or will got with Israel.

    The closest competitors of LCA Tejas Mk.2 are J-10C , JF-17 Bk.3 and F-16 Block 70 along with Saab Gripen-E in single engine category. Tejas Mk.2 in its features will be far more superior to JF-17 Bk.3 as Bk.3 will host those technologies which are already available with Mk.1 and Mk.1A like HMD/S or AESA Radar among others. Bk.3 is not going to offer significant stealth features like Mk.2.

    Tejas Mk.1 can give tough competition to J 10B and is slightly inferior to J10C. Tejas Mk2 with better aerodynamics and more stealth features, can catch up with J10C. Tejas Mk.2 will be a 4++ gen aircraft with tactical strike, air reconnaissance, air defense, and maritime roles which is enough for a light fighter and it can continue upto 2055 till it becomes obsolete.

    This means India need not pour billions of dollars for other 4++ gen aircraft, instead can utilize MK.2 until 2055.

    Comparing to its competitor GRIPEN-E, F-16, Tejas Mk-2 will be equally potent or even better and can definitely be the backbone of light category aircrafts of the IAF.

    Being small and having 45% composite body itself is a stealth feature.

    THE only stealth feature that can be considered r to reduce IR & maximize composite body.....

    Its a excellent rough sketch to show some difference in Mk1 to Mk2. There more than what meets the eye. MK2 is commonly believed to be developed only for navy, but that be wrong. A better through research will give you the following result.
    1. Mk2 is being developed by joint input provided by Navy & IAF both. (repeat including IAF)
    2. post 2024, when MK1A production order finishes, it will continue with mk2 production, for both navy & IAF
    3. Engine will be more powerful GE414 for better thrust (99 has already been ordered), till more powerful kaveri substitute don't fullfill vacuum.
    Expected changes
    • Length increase by 1 meter
    • Head cone, expected to point downwards, for better vision.
    • Wings be bigger.
    • Wings expected to be delta wings like Mk1A but chopped wider delta wing - for better lift
    • This also allow wingtip sensors, suites & missiles, lacking in mk1
    • MK2 Air Inlet be larger & more spaced away than Mk1 as can be seen in sketch.
    • Landing gear to be modified & strengthened for Naval use
    • Also notice difference in landing gear Vs Air inlet - this shows it will have a lot better internal fuel carrying capacity - freeing Mk1A almost permanent fuel droptanks pylons.
    • Thicker midsection also allows more space to integrate pods or more space to attach pods.
    • All these above mean Mk2 will have atleast 2 more hardpoints (wingtip) & 2 hardpoints more free (currently used by fuel droptanks)
    • Mk2 might only use single centerline droptank

    The above is based on hinted & unofficial disclosure, so actual output can be quite different.
    But everyone seems to point project is heading in right direction & on time for 2024 production.

    Compared to it's size , the landing gears of Tejas looks highly over engineered .
