And LCA wasn't mated with the astra when it was ordered. That's how orders have been placed because you can integrate the weapons before the production starts. Re-iterate your last point can't understand what you wrote.
Did you even read what I wrote? Dhruv's first accident was 3 years after it's introduction in 2002. In the case of prachand, the helicopter has been operational for nearly 3 years and hasn't had any incidents or complaints unlike the LUH so *for now* the LCH prachand doesn't contain any issues.
Army and IAF has been operating both the LCH and LUH since 2022 but gave the orders for only the LCH because the LUH still has issues that need to be fixed. This re-iterates that yes *for now* the LCH doesn't have any issues.
