Isn't it? Why do you think TATA is so fast in producing Sikorsky helicopter parts? Because of proper transfer on know how! Why is was bharat forge suddenly capable of building howitzers? Because they took over a foreign company including their know how. Why are we dependent on the Israelis for A2G modes of a 4th gen puls doppler radar? Because we lack the know how! Why do we struggle with developing a subsonic cruise missile, when we get know how of Russia for super and even hypersonic cruise missiles? Because we lack the know how! Why did the Chinese needed so much help from the Ukraine to get their carrier running and navalise their fighters? Because they lacked the know how!
Also ToT is not = ToT! ToT of assembly BARS radar kits or replacing some parts of in with parts produced in India, is not the same as getting full ToT of a modern AESA radar from Thales or Euroradar. The level critical ToT we had in the past was minimal, especially in the Mig years. The MKI deal was the first one, that actually made a difference and still we didn't get critical radar or engine techs, which is exactly what this deal was about to change. The failures of HAL and later GTRE to develop indigenous radars and embarrassment of Kaveri engine, should tell you were we stand on critical technology, just as the fact that our contribution to joint developments is so low. If we remain in the naive world of, we can do it alone, we will waste another 2 decades to achieve, what the world has today. We need input of foreign know how, the one way or the other and that's also why we inplemented the offset policies, why we changed policies to get foreign vendors in JVs with Indian once, or why we want to make India to a production hub for foreign arms and techs. To push Indias industry ahead with the know how we gather and the MMRCA with the highest offset and ToT requirement, was the biggest chance to get to these critical techs on our terms, rather than beg foreigners again like in the LCA development, when our industry failed with their developments.
And now look at AMCA, we already search for a foreign engine supplier, not even a partner for an indigenous engine development, so we already have given up that hope. IRST / optronics know how was possible trough MMRCA, just as TVC or latest avionics and EW capabilities. The only other choice to get the same is, as we recently heared, by GTRE getting into a JV with Klimov for TVC, which again is ToT, or as we did it with the LCA nose and refuelling probe, just import them and licence produce them "under ToT".
