I can list 20 scredrivergiri operations, you list 10 examples where Pvt sector invested billion+ of own money (pre 2014, afterwards they have been forced and incentivised to innovate) for cutting edge tech.
Its easy to blame DRDO/HAL for delays, but most of the blame lies with how democracy works (which is worth the advantages).
Now you raise an issue of 'how Democracy works'. You should be able to answer it yourself that the governments at the head of democracy is bad place to undertake complex projects.
In the case of military & defence, the efficiency of private sector & gov sector depends on government.
In our case, most of the issue lies in GoI, not R&D or manufacturing sector, if gov give a little money to develop 4.5 gen fighter jet engine, no private sector consider working on it. Also corruption is an issue.
Since governments are the main buyers of weapons, private sector need real pre orders & large orders to justify setting up production unit, after that comes r&d, and innovations.
Most of the delay caused by GoI, from sanctions to fund allocations, plus lobbies.
IAF asking for 150~200 EU [reliable & sanction free & not a mig 21 replacement] jets since 2000, now 2022, & when GoI going to fill that hole ? same goes to Awacs, tankers, drones etc. From 1st page of lca mk2 -Tejas Mk2 First Flight
-The Tejas Mk.2 is scheduled to make its first flight in 2014, with full-rate production to follow two years later & GE wanted India to agree to pay liabilities in case the IAF used the engine to power aircraft carrying nuclear weapons and one of these aircraft crashed in Pakistan. I seen GoI rushing to buy weapons during & after war then goes cold.
