I was under the impression that these planes would either augment or replace the existing IN squadrons. Wait, if these are exclusively for the 3rd carrier, then why do people keep discussing whether SH or Rafale will fit in the lifts of INS Vikrant? Further, this doesn't make sense even more now. Consider this, even if the 3rd mythical carrier were to start construction tomorrow, it won't be ready for another decade. Then some years for trials. So you can safely rule out commissioning of another carrier for atleast 15 to 20 years. Why would you buy planes for that now? decade and a half earlier? Deep down everyone here knows that for now, a 65000 ton catobar nuclear carrier is "India ki aukat ke bahar". Most probably it would be another 40k - 45k stobar carrier. TEDBF would work fine on that.
Sure, but the money comes from the same govt. 5 billion or so for another batch of rafale will suck GOI dry. The tender might be released at the same time, but it won't move forward with same speed. Everyone realises that naval aircraft acquisition isn't a priority even for the navy itself, forget the govt. Submarines, Minesweepers, and other vessels are navy's priorities right now.
