Then this article is right?
Maybe extended to roll out by 2025
Production from 2028.
Anyways same was the plan before too..
Mk2 production following Mk1A isn't it?
Question is will 2-3 years enough for mk2 flight testing?
Don't get too worried about the specifics. Any effective warfighting capability will happen only around 2035. The same with AMCA, it will take until 2045 to get enough jets and trained pilots. Any delay will compensate in other aspects, like introduction of other technologies that were not planned on the initial roll-out, including software-unlocks that open up expected combat capabilities.
Yeah, 2-3 years is enough as long as they don't screw it up. The alternative is they will brag about how it's the world's best tested aircraft, just like the F-35. Even Arjun and ATAGS are now the world's best tested tank and artillery gun.
My personal date since many years has always been 2030 and looks like ADA is gonna meet my expectations. That's the best you can expect too. AMCA too, it's 9 years from first flight, without incident. Even though they used to claim 2032, my date has always been 2035. So if they get it flying in 2026, 2035 is the earliest possible date to achieve IOC. So that's at least around 2040 and beyond for FOC and a new engine. That takes us to 2045 to get warfighting capabilities.
So you're worried about first flight and IOC, but the IAF is more interested in FOC + 2 squadrons. Delays in the former can be made up by higher production speed for the latter.
