SameerPlus assuming the late arrival of the Kaveri, an unfortunate fair assumption, the US which will have the say since it will be making the engine will be influencial which may lead countries away from the LCA buy, but the LCA is made for domestic consumption, if we could sell we surely would but we just do not have the capacity at the moment for export
SameerI think that there was interest but let us face it, the IAF needs the LCA quickly and I doubt that HAL can chum out enough LCAs for export.
SameerIndia has been making advanced metal alloys for centuries, we do date back 5000 years you know, if anyone has ay other comment from their x ray vision, please post it here, we will be more than happy to end all this bs once and for all
A great thread
1) We now know that the LCA is not as delayed as some clowns love claiming, articles to proove it
2) INdia can make advanced metal alloys
3) The radar is similar in size to the Gripen
4) The LCA aerodynamics are optimised to beat the M2000, the benchmark of the designers and its delatas, which are cranked produce different vortices than a Viggen!!!!!!
Keep em comming
SameerMan o Man. I did not know Indians are so insecure. Thanks to Arthur and others, these Indians are actually spending their own time to dig up proofs and references. All I have to do is just say “LCA is a failure” or “LCA’s nose cone is too small to fit decent sized radar” or some metallurgical issue related to India or something similar and just sit back and relax, all the information will be handed to me on platter.
This is an aviation forum, we might as well discuss, now this thread can be used as good propaganda tool and as reference, I bet that the same people will ask the exact same questions in a few weeks and post the same articles. I say bring them on, every time they have tried to create something, they have failed miserably and then they jump to another issue, from nose, they loose, then comes metal, now I do not know what it will be but it just goes to show, changing arguments everyday is a sure sign of defeat and/or ignorance.
Sameerand seahawk absolutely the block 60 is 4.5gen, it can surely hold its own vs Typhoon, Rafale, MKIs etc, a fat bird but 4.5th gen non the less.
SameerAs per my prof composites are the future, some debate otherwise, we will have to wait and see if such a design philosophy bears fruit, r&D involves risk, but so far the LCA composites are holding well and the ADA scientists are happy about it, we can give u a source for that too. 🙂
SameerNot really, the Gripen de=oes not seem to have a problem with the American engine , surely it will be a strategic blow, the Kaveri will come, question is when and that is the problem.
This thread is really turning out great, everything that certain fanboy haters have accused us of has been proven with official sources, I wish that all those other speculation threads would do the same someday and that the same critical people would open their mouth in those forums. Keep on asking quesitons, we will keep on posting open source info that you will never be able to come up with for your own country aka J-10 or FC-1 fanboys. But the J-10 is a beautiful bird though, I give it the thumbs up, the LCA, ahh needs a better paint job.
SameerSameer, posting adresses of Indian metal companies doesn’t mean diddly squat if we don’t know what sorts of metals they work with or produce. If they produce aviation-related alloys they’re interesting, but somehow that’s not the idea i get from a company called Saru Smelting Pvt. Ltd.
EDIT – Thanks for the latter one, it nicely nullifies this post.
This is INdia for you, all open to public, it may be corrupt but its democratic
SameerI love my Govt, all is in the open no need to speculate

SameerI think calling the LCA a 4.5 generation fighter is a bit too positive.
It will have better avionics than the Su-30mki due to vetrivale!
It will carry all the modern missiles the IAF has
It will have decent EW and post 2010, note I said that post 2010, it will have an AESA making it 4.5 gen
SameerSaru Smelting Private Limited
Meerut Uttar Pradesh
India
One company that has been operating for years in such a field as metal alloys
SameerSeahawk that is actually more of an interesting theory rather than the nose too small ones, the LCA chose the composite route because we had experience in the field as pointed out on the last page and wanted to make the ploane as light as possible, Harry and others can help with your theory but an interesting one, I am afraid I do not know myself hoow much experience we had in such things in the mid to late 80s when pklans were being drawn up.
SameerIndia obviously lags behind the US, Russia etc, daa, its newer to the field and needs to play catch up, hence you cannot expect it to have F-22 style fighters being made right now, the next plane, aka MCA will be a more important yardstick to see where the Indian aviation industry has gone. The J-10 and company has just started to enter service and will serve for the next 25 years, so will the LCA, itsnot like when the LCA enters service in a few yrs, all it will be facing will be F-22s! The LCA can become quite a potent 4.5gen fighter especially when it comes to avionics and its eventual AESA radar post 2010. The LCA is only ment to hold its own vs J-10s, F-16 clock 50s etc, we are a developing country playing catch p after all, such things as Russian engine Su-30mki tech transfers etc help, collaboration for the PAK fa will also help, I wonder if the Rusians would have asked for Indian collaboration i we did not even have the engineers to help them out,they would have just told us to help fund the project and get cheaper planes later.
