Why cannot we produce the radome indigenously, is there no way we can produce a quartz part. We need at least 120 radome.
Sorry for the late reply.
But first 120 is not a very great number. Cobham type orders can never be generated here in India.
Then there is the additional question of priority to be solved. An aircraft has many different Radomes - datalink, radar, satcom, jammer and some other radome may be taking priority. This is especially important for 'The Untouchables' like LCA. One wrong move and the user will make it an izzat-o-gairat issue. Then there is the additional need keep making radomes for LCA because, as it is, LCA is getting ready for third Radar (MMR-Indian, MMR-Hybrid, 2052, Uttam in future) all with different radome permutations and combinations. On top of that there is similar radome work to be done on other several aircarft upgrades (Jags, probably even Mig-27, Dorniers waghera) and missiles (Akash, Brahmos, Nag waghera). So its not exactly easy either.
BTW even the Kevlar radome takes time while at the same time, given the right resources even the Quartz or freq. selective radome tech should not be an impossible thing to achieve. In the ultimate analysis most tough engineering R&D is essentially a rigorous step by step process of elimination, selection and integration. FSS radomes are a wishlist for AMCA and they will come eventually in Indian make. NAL has apparently done some work in this regard and the following link

Then at times there are considerations like not having to re-invent the wheel.
Unfortunately, if you are relying on foreigners with a large product package, they will of course abuse our order to make you further dependent on them.
So whenever one part of the GoI says that we should not re-invent the wheel and import, that part must normally be queried as to why the wishlist came in at an inopportune time and what plan is there to avoid getting green-mailed.
