turning out to be an excellent Holi !
Typical production run at the minimum is 5-years. Manufacturers won’t do anything shorter and will adjust rates/year accordingly. Users would want them ASAP. Government would need to find adequate funds spread over several years.
With a substantial order of 201 units, there will be 3rd and 4th final assembly lines by private manufacturer along with two lines at HAL. More Tier-1 suppliers of major subassemblies and Tier-2/3 would be required. I would say at least 7-year production run post 2025.
Post Mk2, there would also be pretty big market for Mk.1 MLU. Part of the ecosystem would be continue to be utilized for those major upgrades/overhauls.
there were some excellent posts on Tejas assembly lines, with capacity and expected timeline for completion. anyone can help me locate those ?
Given the 2025 production start date for Mk2, one would expect that for the first couple of years Mk1 & Mk2 production would take place simultaneously, with the smaller capacity Mk1 lines moving to Mk2 first as Mk1 production goes down and moves to Mk2. similarly, starting 2030-32 we might expect AMCA production to slowly supplant Mk2 lines. by 2035 Mk2 production should be coming to an end, but lines may still remain open for exports(if any), making up in-service losses of IAF sqn's and MLU. One would expect a MLU at around 2035 using tech from AMCA project.
