For one, the MKI has a very powerful large aperture antenna. The first radar version gives the MKI a first look capability on LCA irrespective of the RCS difference. That's because the RCS difference isn't very significant.
The French claimed MKIs had superior situational awareness against Rafales and Mirage-2000s with the same radar during exercises. 100NMI according to the French.
The phase 1 upgrade which is already happening will double that already overwhelming capability.
The phase 2 AESA upgrade will quadruple that capability. So while the LCA will be looking for a MKI at a 100-150Km distance due to antenna size limitations in a normal non-electronic environment, the MKI will be looking at LCA class fighters from a greater height and distance of 400 - 500Km and with a theoretical shoot to kill range of 100 - 300Km vs LCA's theoretical kill range of 50 Km.
By the time Su-30 gets 300 Km BVRs . LCA too will get stealth external weapon bays like it is being done on Super hornet evolution and Silent Eagle program for f-15.
Then the RCs of a fully loaded tejas with six air to air BVrs will be just 0.3 sq meters, No ASEA radar will detect a 0.3 sq meter RCs target at any distance greater than 60 or 70 Kms . So tejas will still have the lower RCS advantage over any SU-30 type no matter how longer a BVR it carries and how powerful a radar is mounted on them,
it is just basic physics , it won't vanish any time soon, Not certainly till the ennd of Su-30s and Tejas service life span,
. For your Info even the PAKFA is supposed to have the 0.5 sq meter RCS with it's BVR missiles in it's internal bomb bay.
Tejas has a kill range of 50 Km only in your Phd thesis. Go to Wiki and check out what are the missiles that will be eligible for tejas and see their range, Leave Akash mk-1 and Mk-2. ADA chief himself has stated on the record that Tejas mk-2 will have the interface to fire meteor 120 Km range BVR just like Grippen.
In a dense electronic environment the MKI's radar capability won't be significantly diminished due to the higher ratings of the radar. On the other hand the LCA's radar capability will be diminished. Apart from that's its EW suite won't be able to keep up against MKI's ECM capability for two reasons. One the MKIs EW suite is simply far far more advanced than what is being planned for LCA. Second, the MKI simply delivers much more power and hence is more useful at longer distances. So all electronic advantages lie with MKI.
There will be three tejas mk-2 in air for every SU-30 in air if you compare the latest lifecycle costs, SO a single Su-30 jamming suite will have to suppress all three tejas radars simultaneously , never going to happen in real time, especially with latest ASEA radars.
Also much bigger emissions from SU-30 will give a trackable targeting co ords from much longer distances for long range radar homing missiles, SO higher power radar has advantages and disadvantages at the same time.
In terms of aircraft capability, the MKI has greater speed, greater altitude options, greater turn rates, roll rates , greater climb rates, overall greater maneuverability and overall greater combat sustainability and survivability.
Meaning, MKI can outturn, outrun and outclimb LCA on any day. At the same time it can sustain combat operations 4-5 times longer. A sustained dog fight time limit is 5 minutes for LCA, it is 25 minutes for MKI. The MKI has far more fuel to burn and burns it less slowly during cruise flight.
give the specs with source before tumbling out with stats, For your info LCA mk-2 will have an engine more powerful with no significant weight addition massively improving it's TWR vis a vis any fighter on the planet.
the heavier engines on Su-30 will have to support the massive dead empty weight of Su-30s which are built for long range, heavy fuel load, heavy weapon load requirements, with significant momentum penalties
not a rosy proposition when you face a high TWR low weight , fighter with very low wing loading along with lower fuel load and weapon load specs.
Especially in close combat for the same cost one SU-30 has to duel with 3 tejas fighters the odds are not as rosy as you suggest.
A regular MKI mission can go on for 3-4 hours while LCA needs to land back in 40 minutes on internal fuel. MKI currently does not carry any external fuel, but with external fuel, the LCA can manage a one hour 10 minute mission at most. If you compare fuel loads, LCA can fly a little over 1 hour with around 5 tonnes of fuel while MKI can stay in the air for 3.5 hours with 9.5 tonnes of fuel. It has a lot to do with drag and payload. MKI can carry a larger payload and still better the LCA any day.
LCA was built with very low wing loading , high TWR, close combat interception of heavy dead weight long range fighters like SU-30. So it is meaningless to compare the flight times of both tejas and Su-30.
In close combat tejas will carry out missions in 300 km around border area along with ops over domestic air space, so no time on station penalties, here,
Technically, there is no chance at all. On paper, a MKI can be beaten by the LCA class only if the pilot makes a heinous mistake.
Or people like you post such incorrect stuff to mislead gullible Su-30 pilots lulling them to complacency.
truth is opposite big fighters won't fare as mighty as their specs when confronted with more in number nimble state of the art low RCS , high TWR, low wing loading fighters like tejas in close combat ,
There is something called visual stealth that you have completely forgotten, as well
The difference between Rafale and LCA isn't as overwhelming, but Rafale's A2G capability and EW suite is simply outstanding and incomparable to LCA's. In certain respects even MKI is currently deficient in some capabilities the Rafale brings in.
Exactly that is why it is a waste of money to pour 20 billion dollars on the rafale. while for the same price we can get about 600 or 700 tejas mk-2 fighters, making the skies of India a sentinel .
EW suits evolve over time and will be added in MLUs nothing specific to airframe though.
As for crash rate, nearly 200 MKIs or more are already operational with 4 crashes. 0 LCAs are operational with 0 crashes. Moot.
While it is disappointing that the Mig-21s are being pushed beyond their limits, however the comparison is moot. LCA doesn't exist while 200+ Mig-21s do. The LCA is years away from being combat ready.
With age comes experience. How many pilots exist in India today with over 1000-2000 hours on Tejas? Tell me. You can guess what all our top and experience pilots are flying today. Some of our best pilots are on the Mig-21 and Jaguar squadrons. The LCA is just a baby. A new pilot, no matter how experienced will still be learning to fly the LCA. If you look at LCA's development schedule, IOC and FOC are just the start for IAF. The 40 LCAs will still undergo 5 years of test flying within the IAF. It will be 5 years after induction that ADA will be withdrawn from the project and IAF will be given free lease on the aircraft. Meaning until 2020 IAF will only be flying mostly test sorties on basic MK1 fighters while waiting for MK2 version. Flying the aircraft as a death machine will start years later.
As an example, JF-17 was given IOC in 2006, it has still not achieved FOC. It should receive FOC either this year end of early next year, whenever they receive the Block 2 that is. As of today they have three squadrons and all three are trainer and conversion squadrons. Only the earliest pilots and only a handful of jets are combat capable as of today. That's 6 years after induction. It won't be any different for LCA too. By the time LCA is ready for actual combat missions, Mig-21s will be long gone.
LCAs won't be of much use against China. Mostly MKIs and Rafales in that area, all the top air force stations in the area belong to MKIs and Rafales. It is doubtful whether LCAs will even be placed in the North-East. As of today, the permanent home base for the 2 MK1 squadrons will be Sulur in Tamil Nadu. Mk2s, we are inducting only 4 squadrons. So two squadrons each in two AFS in the western border supporting the 5 Jaguar squadrons, all of which are placed in the west like Punjab(2), Maharashtra(1) and UP(2). Mig-27s will be gone before MK1s are fully inducted and replaced with Rafales.
